Student's Patterns of Interaction with a Mathematics Intelligent Tutor: Learn...IJITE
Purpose: The purpose of this paper is to determine potential identifiers of students’ academic success in foundation mathematics course by analyzing the data logs of an intelligent tutor.
Design/ methodology/approach: A cross-sectional study design was used. A sample of 58 records was extracted from the data-logs of the intelligent tutor, ALEKS. This data was triangulated with the data collected from surveys. Two-step clustering, correlation and regression analysis, Chi-square analysis and paired sample t-tests were applied to address the research questions.
Findings: The data-logs of ALEKS include information about number of topics practiced and number of topics mastered by each student. Prior knowledge and derived attribute, which is the ratio of number of topics mastered to number of topics practiced(denoted by the variable m top in this paper) are found to be predictors of final marks in the foundation mathematics course with = 42%.
Students were asked to report their preferred way of selecting topics as either sequential or random. Results of paired sample t-test demonstrated that the students who selected topics in a sequential manner were able to retain their mastery of learning after the summative assessment whereas the students who chose topics randomly were not able to retain their mastery of learning.
Originality and value: This research has established three indicators of academic success in the course of foundation mathematics which is delivered using the intelligent tutor ALEKS. Instructors can monitor students’ progress and detect students at-risk who are not able to attain desired pace of learning and guide them to choose the correct sequence of topics.
This was a field research (literature review and exploration) with descriptive quantitative approach. This study aims: (1) to develop a model (scheme) to assess mathematical power, (2) to test the validity of instruments of mathematical power assessment, and (3) to developa valid and reliable test and non-test instrument prototypes as a mathematical power measurement. The research instruments consist of 4 items of essay test, 20 sheets of observation on investigative activities, and 20 items of questionnaires. Validity test was conducted through constructions built up from 3 aspects of mathematical power ability. Result of instrument analysis showed that: (1) the r of instrument test = 0.947, meaning that the instrument is reliable, (2) the r of activity observation sheets = 0.912, meaning that the instrument is reliable, and (3) the r of questionnaires = 0.770, meaning that the questionnaire is reliable on 0.05 significance level. This study concludes: (a) the steps in the model (scheme) of mathematical power assessment may be used as a reference for assessing mathematical power, (b) test and non-test instruments are valid and reliable, and (c) prototypes of test and non-test instruments may be used as a measurement in mathematical power assessment.
Educational Data Mining is used to find interesting patterns from the data taken from
educational settings to improve teaching and learning. Assessing student’s ability and performance with
EDM methods in e-learning environment for math education in school level in India has not been
identified in our literature review. Our method is a novel approach in providing quality math education
with assessments indicating the knowledge level of a student in each lesson. This paper illustrates how
Learning Curve – an EDM visualization method is used to compare rural and urban students’ progress
in learning mathematics in an e-learning environment. The experiment is conducted in two different
schools in Tamil Nadu, India. After practicing the problems the students attended the test and their
interaction data are collected and analyzed their performance in different aspects: Knowledge
component level, time taken to solve a problem, error rate. This work studies the student actions for
identifying learning progress. The results show that the learning curve method is much helpful to the
teachers to visualize the students’ performance in granular level which is not possible manually. Also it
helps the students in knowing about their skill level when they complete each unit.

Method used for development using four phases: Design, Construction, Testing, Evaluation and Revision. The criteria used to assess the quality of the learning device refer to the material quality criteria namely: validity, practicality, effectiveness. Subject of trials in this research are 25 students of XI IPA-4 and 25 students of XI IPA-2. Two indicators of this study are metacognitive skills and problem solving. Metacognitive skills are: prediction skills, planning skills, monitoring skills, and evaluation skills. Indicators of problem solving are: understanding the problem, devising a plan, carrying out the plan, and looking back. The data are collected by giving Tests and questionnaires, and through observations. The research instruments are: questionnaire of validation for teaching materials, student questionnaire responses to instructional materials, observation sheet activities of learners, observation sheets of learning implementation and learning management observation sheet. The result of this research is metacognitive skills-based teaching materials are succeeded (fulfilling the criteria of valid, practical, and effective) to emerge students mathematical problem-solving.
This research was conducted due to the importance value of mathematics for early childhood and the fact some researches showed the early childhood education (ECE) teachers' low level of basic mathematical knowledge, especially the one related to childhood developmental stages. The participants of this research were 35 ECE teachers from one of the cities in West Java province with teaching experience approximately ten years. In this research, 30 minutes was given to the participants to solve 20 questions, which tested teachers' knowledge related to verbal counting sequence, counting, the ordinal number of words, addition/subtraction, divisions of sets, written number symbols, and words. Besides, the interview was conducted to get more indepth information from the participants. The quantitative descriptive analysis was used to identify the frequency, percentage, mean value, and standard deviation. The result of the research showed that ECE teachers had limited knowledge of children's mathematical development. It was revealed by the result of the mean value of the teachers’ responses, which were only 33% correct answers and 16% no idea answers. This result can become input for the stakeholders to hold a professional development program which aims to increase the quality of ECE teachers related to mathematical development activity.
A learning program not only aims to make students understand and master what and how things happen, but also provide an understanding of why it happened. Thus, a lesson that emphasizes problem-solving becomes very important to teach. One form of learning that emphasizes the problem solving is to apply systematic approach to problem solving. This is a guide to perform an action that serves to assist a person in solving a problem. Problem solving steps based on systematic approach to problem solving consists of four stages, namely problem analysis, problem solving process planning, calculation operations, and checking answers and interpretation of results. This study is a classroom action research that aims to see the inceasing of student learning outcomes after applied systematic approach to problem solving. The subject of this research is 25 students of class VIIIA MTs Salafiyah Syafi'iyah Tebuireng Jombang. Instruments in this study is a matter of student learning outcomes on the material wake up space. This research was conducted in two cycles because in the second cycle has reached the indicator of success that students achieve the minimal clarity of at least 75%. The results showed that student learning outcomes in the first cycle reached 36% classical completeness, and in the second cycle of classical completeness of 84%. This shows that the application of systematic approach to problem solving can increase student learning outcomes.

STUDENTS’PATTERNS OF INTERACTION WITH A MATHEMATICS INTELLIGENT TUTOR:LEARNIN...IJITE
Purpose: The purpose of this paper is to determine potential identifiers of students’ academic success in
foundation mathematics course by analyzing the data logs of an intelligent tutor.
Design/ methodology/approach: A cross-sectional study design was used. A sample of 58 records was
extracted from the data-logs of the intelligent tutor, ALEKS. This data was triangulated with the data
collected from surveys. Two-step clustering, correlation and regression analysis, Chi-square analysis and
paired sample t-tests were applied to address the research questions.
Findings: The data-logs of ALEKS include information about number of topics practiced and number of
topics mastered by each student. Prior knowledge and derived attribute, which is the ratio of number of
topics mastered to number of topics practiced(denoted by the variable m top in this paper) are found to be
predictors of final marks in the foundation mathematics course with
= 42%.
Students were asked to report their preferred way of selecting topics as either sequential or random.
Results of paired sample t-test demonstrated that the students who selected topics in a sequential manner
were able to retain their mastery of learning after the summative assessment whereas the students who
chose topics randomly were not able to retain their mastery of learning.
Originality and value: This research has established three indicators of academic success in the course of
foundation mathematics which is delivered using the intelligent tutor ALEKS. Instructors can monitor
students’ progress and detect students at-risk who are not able to attain desired pace of learning and guide
them to choose the correct sequence of topics.

The aim of the study was to determine the concepts that primary school
fourth-grade students reveal with their mind maps related to four operations
(addition, subtraction, multiplication, division) and to compare the mind map
and achievement test scores. In the study, a mixed method was used in which
quantitative and qualitative data were collected and presented together. The
study was carried out with a total of 14 students. There were eight girls and
six boys, who studying in the fourth-grade of a primary school in Menteşe
district of Muğla, in the spring semester of the 2019-2020 academic year. In
the research, mind maps created for four operations and success test were
used as data collection tools. The data collection process was carried out
simultaneously. In the analysis of the data, qualitative data were transformed
into the quantitative analysis, and quantitative analyzes were made. Concepts
in mind maps created for four operations were subjected to qualitative
analysis and photos were added as evidence. As a result of the research, it
was determined that the majority of the students adopted the concepts of
addition, subtraction, multiplication, and division. Besides, it was revealed
that there was a high-level positive relationship between the scores of the
students obtained from the achievement test and the scores from the mind
maps they created. The evaluation made using the mind map for primary
school fourth-grade students is more advantageous than the achievement test
in terms of determining the conceptual understanding.
Smart Curriculum Mapping and Its Role in Outcome-based EducationAlAtfat
Educational development processes are essential for successful academic performance in educational and
technical environments. Teachers and students also need a model and guidelines required for effective
learning. Without effective curriculum mapping, the institutions cannot accurately estimate outcomes and
maximize potential performance on resources. A matrix depicts the relationship between student learning
outcomes (SOs) and topics on the curricular map. The need to earn satisfying produce of education and
achieve considerable progress in the visibility of education equity in completing professional duties is a
primary motivation for learning the curriculum. One of the most effective strategies to increase overall
teaching effectiveness, involvement, or curricular interaction is curriculum development. The mapping
connects all disciplines to academic outcomes and displays well-planned teaches. An excellent example
of a curriculum should be well-prepared and purposefully encourage expertise acquisition. This paper
describes a set of range standards and recommendations for this technique and challenges that affect
curricular map construction. As a result, this strategy will increase the overall performance of education
and the quality of the curriculum.

Problem-based learning is generally done with face-to-face interaction. This learning process, however, has not provided a lot of time for learners to find limitless and timeless information and learning resources. It still depends on the teacher as a source of information. Students are very dependent on the presence of lecturers during face-to-face interaction. This research aims to develop a Problem-based Blended Learning (PB2L) model to support student to improve their creative thinking skills. The method used in this research was R&D with ASSURE development model. Product validation was done through an expert’s assessment by using the expert’s validation sheet. The practicality of the product is tested with limited trials with college lecturers and some students with questionnaires and interviews. Product effectiveness was seen by implementing limited development testing to a particular class with a one group pretest-posttest design and the result was analyzed by using a Paired-Samples T-Test. The result of this research is a Problem-based Blended Learning (PB2L) valid, practical and effectively improves students' creative thinking abilities. The effectiveness of the learning model was also proven on the basis of Paired-Samples T-Test of students’ pretest and posttest with sig. (2-tailed) 0.000. This learning gives students the opportunity to think systematically by beginning by criticizing the interesting contextual problems and ending with meaningful reflection with adequate learning resources both in face-to-face and online interaction.

A Novel Method for Prevention of Bandwidth Distributed Denial of Service AttacksIJERD Editor
Distributed Denial of Service (DDoS) Attacks became a massive threat to the Internet. Traditional
Architecture of internet is vulnerable to the attacks like DDoS. Attacker primarily acquire his army of Zombies,
then that army will be instructed by the Attacker that when to start an attack and on whom the attack should be
done. In this paper, different techniques which are used to perform DDoS Attacks, Tools that were used to
perform Attacks and Countermeasures in order to detect the attackers and eliminate the Bandwidth Distributed
Denial of Service attacks (B-DDoS) are reviewed. DDoS Attacks were done by using various Flooding
techniques which are used in DDoS attack.
The main purpose of this paper is to design an architecture which can reduce the Bandwidth
Distributed Denial of service Attack and make the victim site or server available for the normal users by
eliminating the zombie machines. Our Primary focus of this paper is to dispute how normal machines are
turning into zombies (Bots), how attack is been initiated, DDoS attack procedure and how an organization can
save their server from being a DDoS victim. In order to present this we implemented a simulated environment
with Cisco switches, Routers, Firewall, some virtual machines and some Attack tools to display a real DDoS
attack. By using Time scheduling, Resource Limiting, System log, Access Control List and some Modular
policy Framework we stopped the attack and identified the Attacker (Bot) machines
Hearing loss is one of the most common human impairments. It is estimated that by year 2015 more
than 700 million people will suffer mild deafness. Most can be helped by hearing aid devices depending on the
severity of their hearing loss. This paper describes the implementation and characterization details of a dual
channel transmitter front end (TFE) for digital hearing aid (DHA) applications that use novel micro
electromechanical- systems (MEMS) audio transducers and ultra-low power-scalable analog-to-digital
converters (ADCs), which enable a very-low form factor, energy-efficient implementation for next-generation
DHA. The contribution of the design is the implementation of the dual channel MEMS microphones and powerscalable
ADC system.
Influence of tensile behaviour of slab on the structural Behaviour of shear c...IJERD Editor
-A composite beam is composed of a steel beam and a slab connected by means of shear connectors
like studs installed on the top flange of the steel beam to form a structure behaving monolithically. This study
analyzes the effects of the tensile behavior of the slab on the structural behavior of the shear connection like slip
stiffness and maximum shear force in composite beams subjected to hogging moment. The results show that the
shear studs located in the crack-concentration zones due to large hogging moments sustain significantly smaller
shear force and slip stiffness than the other zones. Moreover, the reduction of the slip stiffness in the shear
connection appears also to be closely related to the change in the tensile strain of rebar according to the increase
of the load. Further experimental and analytical studies shall be conducted considering variables such as the
reinforcement ratio and the arrangement of shear connectors to achieve efficient design of the shear connection
in composite beams subjected to hogging moment.
Gold prospecting using Remote Sensing ‘A case study of Sudan’IJERD Editor
Gold has been extracted from northeast Africa for more than 5000 years, and this may be the first
place where the metal was extracted. The Arabian-Nubian Shield (ANS) is an exposure of Precambrian
crystalline rocks on the flanks of the Red Sea. The crystalline rocks are mostly Neoproterozoic in age. ANS
includes the nations of Israel, Jordan. Egypt, Saudi Arabia, Sudan, Eritrea, Ethiopia, Yemen, and Somalia.
Arabian Nubian Shield Consists of juvenile continental crest that formed between 900 550 Ma, when intra
oceanic arc welded together along ophiolite decorated arc. Primary Au mineralization probably developed in
association with the growth of intra oceanic arc and evolution of back arc. Multiple episodes of deformation
have obscured the primary metallogenic setting, but at least some of the deposits preserve evidence that they
originate as sea floor massive sulphide deposits.
The Red Sea Hills Region is a vast span of rugged, harsh and inhospitable sector of the Earth with
inimical moon-like terrain, nevertheless since ancient times it is famed to be an abode of gold and was a major
source of wealth for the Pharaohs of ancient Egypt. The Pharaohs old workings have been periodically
rediscovered through time. Recent endeavours by the Geological Research Authority of Sudan led to the
discovery of a score of occurrences with gold and massive sulphide mineralizations. In the nineties of the
previous century the Geological Research Authority of Sudan (GRAS) in cooperation with BRGM utilized
satellite data of Landsat TM using spectral ratio technique to map possible mineralized zones in the Red Sea
Hills of Sudan. The outcome of the study mapped a gossan type gold mineralization. Band ratio technique was
applied to Arbaat area and a signature of alteration zone was detected. The alteration zones are commonly
associated with mineralization. The alteration zones are commonly associated with mineralization. A filed check
confirmed the existence of stock work of gold bearing quartz in the alteration zone. Another type of gold
mineralization that was discovered using remote sensing is the gold associated with metachert in the Atmur
Desert.
Reducing Corrosion Rate by Welding DesignIJERD Editor
The paper addresses the importance of welding design to prevent corrosion at steel. Welding is
used to join pipe, profiles at bridges, spindle, and a lot more part of engineering construction. The
problems happened associated with welding are common issues in these fields, especially corrosion.
Corrosion can be reduced with many methods, they are painting, controlling humidity, and also good
welding design. In the research, it can be found that reducing residual stress on the welding can be
solved in corrosion rate reduction problem.
Preheating on 500oC and 600oC give better condition to reduce corosion rate than condition after
preheating 400oC. For all welding groove type, material with 500oC and 600oC preheating after 14 days
corrosion test is 0,5%-0,69% lost. Material with 400oC preheating after 14 days corrosion test is 0,57%-0,76%
lost.
Welding groove also influence corrosion rate. X and V type welding groove give better condition to reduce
corrosion rate than use 1/2V and 1/2 X welding groove. After 14 days corrosion test, the samples with
X welding groove type is 0,5%-0,57% lost. The samples with V welding groove after 14 days corrosion test is
0,51%-0,59% lost. The samples with 1/2V and 1/2X welding groove after 14 days corrosion test is 0,58%-
0,71% lost.

Active Power Exchange in Distributed Power-Flow Controller (DPFC) At Third Ha...IJERD Editor
This paper presents a component within the flexible ac-transmission system (FACTS) family, called
distributed power-flow controller (DPFC). The DPFC is derived from the unified power-flow controller (UPFC)
with an eliminated common dc link. The DPFC has the same control capabilities as the UPFC, which comprise
the adjustment of the line impedance, the transmission angle, and the bus voltage. The active power exchange
between the shunt and series converters, which is through the common dc link in the UPFC, is now through the
transmission lines at the third-harmonic frequency. DPFC multiple small-size single-phase converters which
reduces the cost of equipment, no voltage isolation between phases, increases redundancy and there by
reliability increases. The principle and analysis of the DPFC are presented in this paper and the corresponding
simulation results that are carried out on a scaled prototype are also shown.
Mitigation of Voltage Sag/Swell with Fuzzy Control Reduced Rating DVRIJERD Editor
Power quality has been an issue that is becoming increasingly pivotal in industrial electricity
consumers point of view in recent times. Modern industries employ Sensitive power electronic equipments,
control devices and non-linear loads as part of automated processes to increase energy efficiency and
productivity. Voltage disturbances are the most common power quality problem due to this the use of a large
numbers of sophisticated and sensitive electronic equipment in industrial systems is increased. This paper
discusses the design and simulation of dynamic voltage restorer for improvement of power quality and
reduce the harmonics distortion of sensitive loads. Power quality problem is occurring at non-standard
voltage, current and frequency. Electronic devices are very sensitive loads. In power system voltage sag,
swell, flicker and harmonics are some of the problem to the sensitive load. The compensation capability
of a DVR depends primarily on the maximum voltage injection ability and the amount of stored
energy available within the restorer. This device is connected in series with the distribution feeder at
medium voltage. A fuzzy logic control is used to produce the gate pulses for control circuit of DVR and the
circuit is simulated by using MATLAB/SIMULINK software.
Study on the Fused Deposition Modelling In Additive ManufacturingIJERD Editor
Additive manufacturing process, also popularly known as 3-D printing, is a process where a product
is created in a succession of layers. It is based on a novel materials incremental manufacturing philosophy.
Unlike conventional manufacturing processes where material is removed from a given work price to derive the
final shape of a product, 3-D printing develops the product from scratch thus obviating the necessity to cut away
materials. This prevents wastage of raw materials. Commonly used raw materials for the process are ABS
plastic, PLA and nylon. Recently the use of gold, bronze and wood has also been implemented. The complexity
factor of this process is 0% as in any object of any shape and size can be manufactured.

Secure Image Transmission for Cloud Storage System Using Hybrid SchemeIJERD Editor
- Data over the cloud is transferred or transmitted between servers and users. Privacy of that
data is very important as it belongs to personal information. If data get hacked by the hacker, can be
used to defame a person’s social data. Sometimes delay are held during data transmission. i.e. Mobile
communication, bandwidth is low. Hence compression algorithms are proposed for fast and efficient
transmission, encryption is used for security purposes and blurring is used by providing additional
layers of security. These algorithms are hybridized for having a robust and efficient security and
transmission over cloud storage system.
Application of Buckley-Leverett Equation in Modeling the Radius of Invasion i...IJERD Editor
A thorough review of existing literature indicates that the Buckley-Leverett equation only analyzes
waterflood practices directly without any adjustments on real reservoir scenarios. By doing so, quite a number
of errors are introduced into these analyses. Also, for most waterflood scenarios, a radial investigation is more
appropriate than a simplified linear system. This study investigates the adoption of the Buckley-Leverett
equation to estimate the radius invasion of the displacing fluid during waterflooding. The model is also adopted
for a Microbial flood and a comparative analysis is conducted for both waterflooding and microbial flooding.
Results shown from the analysis doesn’t only records a success in determining the radial distance of the leading
edge of water during the flooding process, but also gives a clearer understanding of the applicability of
microbes to enhance oil production through in-situ production of bio-products like bio surfactans, biogenic
gases, bio acids etc.
Gesture Gaming on the World Wide Web Using an Ordinary Web CameraIJERD Editor
- Gesture gaming is a method by which users having a laptop/pc/x-box play games using natural or
bodily gestures. This paper presents a way of playing free flash games on the internet using an ordinary webcam
with the help of open source technologies. Emphasis in human activity recognition is given on the pose
estimation and the consistency in the pose of the player. These are estimated with the help of an ordinary web
camera having different resolutions from VGA to 20mps. Our work involved giving a 10 second documentary to
the user on how to play a particular game using gestures and what are the various kinds of gestures that can be
performed in front of the system. The initial inputs of the RGB values for the gesture component is obtained by
instructing the user to place his component in a red box in about 10 seconds after the short documentary before
the game is finished. Later the system opens the concerned game on the internet on popular flash game sites like
miniclip, games arcade, GameStop etc and loads the game clicking at various places and brings the state to a
place where the user is to perform only gestures to start playing the game. At any point of time the user can call
off the game by hitting the esc key and the program will release all of the controls and return to the desktop. It
was noted that the results obtained using an ordinary webcam matched that of the Kinect and the users could
relive the gaming experience of the free flash games on the net. Therefore effective in game advertising could
also be achieved thus resulting in a disruptive growth to the advertising firms.
Hardware Analysis of Resonant Frequency Converter Using Isolated Circuits And...IJERD Editor
-LLC resonant frequency converter is basically a combo of series as well as parallel resonant ckt. For
LCC resonant converter it is associated with a disadvantage that, though it has two resonant frequencies, the
lower resonant frequency is in ZCS region[5]. For this application, we are not able to design the converter
working at this resonant frequency. LLC resonant converter existed for a very long time but because of
unknown characteristic of this converter it was used as a series resonant converter with basically a passive

series resonant tank of Lr and Cr converter acts very similar to Series Resonant Converter. The benefit of LLC
resonant converter is narrow switching frequency range with light load[6] . Basically, the control ckt plays a
very imp. role and hence 555 Timer used here provides a perfect square wave as the control ckt provides no
slew rate which makes the square wave really strong and impenetrable. The dead band circuit provides the
exclusive dead band in micro seconds so as to avoid the simultaneous firing of two pairs of IGBT’s where one
pair switches off and the other on for a slightest period of time. Hence, the isolator ckt here is associated with
each and every ckt used because it acts as a driver and an isolation to each of the IGBT is provided with one
exclusive transformer supply[3]. The IGBT’s are fired using the appropriate signal using the previous boards
and hence at last a high frequency rectifier ckt with a filtering capacitor is used to get an exact dc
waveform .The basic goal of this particular analysis is to observe the wave forms and characteristics of
converters with differently positioned passive elements in the form of tank circuits.

“MS-Extractor: An Innovative Approach to Extract Microsatellites on „Y‟ Chrom...IJERD Editor
Simple Sequence Repeats (SSR), also known as Microsatellites, have been extensively used as
molecular markers due to their abundance and high degree of polymorphism. The nucleotide sequences of
polymorphic forms of the same gene should be 99.9% identical. So, Microsatellites extraction from the Gene is
crucial. However, Microsatellites repeat count is compared, if they differ largely, he has some disorder. The Y
chromosome likely contains 50 to 60 genes that provide instructions for making proteins. Because only males
have the Y chromosome, the genes on this chromosome tend to be involved in male sex determination and
development. Several Microsatellite Extractors exist and they fail to extract microsatellites on large data sets of
giga bytes and tera bytes in size. The proposed tool “MS-Extractor: An Innovative Approach to extract
Microsatellites on „Y‟ Chromosome” can extract both Perfect as well as Imperfect Microsatellites from large
data sets of human genome „Y‟. The proposed system uses string matching with sliding window approach to
locate Microsatellites and extracts them.
Importance of Measurements in Smart GridIJERD Editor
- The need to get reliable supply, independence from fossil fuels, and capability to provide clean
energy at a fixed and lower cost, the existing power grid structure is transforming into Smart Grid. The
development of a smart energy distribution grid is a current goal of many nations. A Smart Grid should have
new capabilities such as self-healing, high reliability, energy management, and real-time pricing. This new era
of smart future grid will lead to major changes in existing technologies at generation, transmission and
distribution levels. The incorporation of renewable energy resources and distribution generators in the existing
grid will increase the complexity, optimization problems and instability of the system. This will lead to a
paradigm shift in the instrumentation and control requirements for Smart Grids for high quality, stable and
reliable electricity supply of power. The monitoring of the grid system state and stability relies on the
availability of reliable measurement of data. In this paper the measurement areas that highlight new
measurement challenges, development of the Smart Meters and the critical parameters of electric energy to be
monitored for improving the reliability of power systems has been discussed.
Study of Macro level Properties of SCC using GGBS and Lime stone powderIJERD Editor
One of the major environmental concerns is the disposal of the waste materials and utilization of
industrial by products. Lime stone quarries will produce millions of tons waste dust powder every year. Having
considerable high degree of fineness in comparision to cement this material may be utilized as a partial
replacement to cement. For this purpose an experiment is conducted to investigate the possibility of using lime
stone powder in the production of SCC with combined use GGBS and how it affects the fresh and mechanical
properties of SCC. First SCC is made by replacing cement with GGBS in percentages like 10, 20, 30, 40, 50 and
by taking the optimum mix with GGBS lime stone powder is blended to mix in percentages like 5, 10, 15, 20 as
a partial replacement to cement. Test results shows that the SCC mix with combination of 30% GGBS and 15%
limestone powder gives maximum compressive strength and fresh properties are also in the limits prescribed by
the EFNARC.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

The Effect of Information and Communication Technology Application on
Graph Theory Education
Morteza Gorzinnezhad
PhD Scholar, Teachers University, Sari-Iran 2013
Abstract:- In order to study the effect of information and communication technology on math learning from
two classes of mathematics, students in Mazandaran teachers' university (Dr. Shariati Campus, Sari,
Mazandaran, Iran),one class was selected as an experimental group and the other as a control group. The graph
subject in the lesson discrete mathematics was taught to the experimental group by using NEWGRAPH
educational software that is a kind of dynamic interactive software and the same subject was taught to the
control group without this software. At the beginning of this course, a pretest was applied and at the end of it, a
post test was held. The results of using unilateral covariance analysis indicated that the experimental group' s
scores were better than those of the control group in the significance level p<0.05.This research, also, is going
to answer the following questions: To teach mathematics, should teaching totally be done by using modern
technology and/ or combination of the other teaching methods, and which strategies can we use except or better
than technology?
Keywords:- information and communication technology, educational software, math learning
I. INTRODUCTION
Different methods have been used in math education during history. Most of researches about the role
of technology in math education frequently have been dealt with general advantages of technology. In this
paper, some advantages of technology combination in math education and especially two important advantages
such as visualization and feedback, while using computer are studied. Some of the teaching patterns which can
be adopted regarding to the advantages of technology combination without using technology will be represented
according to the result of quantitative and qualitative analysis. In order to use technology in math education
comprehensively and its new and different application, Kimmins states the role of technology to help the
development of mathematical skills and concept in problem solving, growing mathematical arguments and
relationships. [1]Also, Aminifar suggests different application of information education communication
technology which can help math education as fast feedback providers for students and tools of accurate and fast
visual presentation of mathematical forms in order to use these forms by students and opportunity to show their
effects. Then, he introduces educational technology as a help for those calculations that cannot be done by hand
and their main objective is not calculation skills. [2]
Although, different aspects of information technology have been emphasized frequently, teachers
should guide and support students. The use of technology in math class should not lead to technical confusion
and limitation. Students should use the tool to facilitate the creation of mathematical objects, to make
mathematical exercises on the objects possible and to provide an absolute reason of those exercises'
consequences.[3]
One of the most important advantages of using computer in math education is multiple representation
and feedback by using computer.
Multiple representation and visualization by using computer: the role of technology in math education
and multiple representation and visualization by using computer have been focused by different researchers.
Valinejad et al have emphasized the significance of visualization in math education. They believe an image is
more valuable than one thousand words, thus, they stipulate the role of visualization-based education in
accurate, fast and explicit questioned concepts.[4]
Mathematical tendency subjects as cognitive tools can reduce tasks through doing less important
components, therefore, strengthen high-order thinking and hypothesis testing and create high degree of
mathematical and cognitive fidelity which is provided with technology while making representation. Multiple
representations of math objects can strengthen the relationship among different math concepts and deepen
students' learning.
Serpil et al define visualization as an act in which one makes bilateral representation between internal
structures and some external factors. An act of visualization consists of any imagination of object or events by
an external source.

Similarly, visualization can have a structure depend on some external media such as objects or events.
Also, visualization is translation and transfer from out to mind. It is a useful method and powerful source for
students to do Mathematics. This method is beyond different thinking methods in Mathematics that results from
predicative and linguistic logic thinking, symbolic and traditional use of old algebra.
Visualization approach prepares students to study math objects that are group of abstract structures and
concepts in different perspectives. [5]Visualization is processes, data, organizational structures, places,
sequences, generalizations, theories, emotions and attitudes. Visualization methods range changes from
emphasizing diagram in text by coloring to create a completed diagram and nonverbal presentation.[6]
It is said that for example scientific Visualizations in classes are providing information with new methods for
acceleration students' perceptions. These Visualizations may include simulating a scientific rule for new
classification of information that clarify scientific explanation elements or a new method for organizing data
(for example, using colors as heat index). Visualizations use theoretical symbols of color, sing and sound to
help students to recognize elements to perceive its results. Also, the acts similar to reality of simulation that
sometimes can be used for hypotheses testing and problem solving are useful. [7]Visualization causes
perceptions of different events even by a glance.[8]
Conception of visualization may differ from related observation. For instance, when the teacher draws
an incomplete circle on the board that is not a circle, because the circle is not drawn completely. Of course for
one who knows a circle is a set of points at page they are in the same distance from center, the image on the
board is enough to make understanding for the teacher is speaking about " Mathematical circle ". Yet, for the
student who knows nothing about circle concept previously, the image on the board may have other meanings,
so visual imaginations are enough to convince oneself absolutely, if one have enough knowledge about
something which is shown [9] .The advantages of using Visualization and multiple representation in math
education can realize better by computer.
Even though in some mathematical subjects, visualization and intuition is not possible without using
computer and educational software. Computer is the main tool for mathematical research and application.
Computer software can provide mathematical objects Visualization easily. If there is no such visualization and
presentation, learning will become even harder [10], above subjects that emphasize the significance of mental
Visualization and imagination by using computer.
II. COMPUTER FEEDBACK
Computer feedback and interaction and dealing with Mathematical subjects by using computer have
strong effect on students' learning. Feed back is a reaction to students' learning behavior and includes verbal and
nonverbal reaction’ for example’ mentioning. Attracting attention and proposing are next steps [11].
Computer is used to extend human mental abilities. Computers are flexible and can provide feedback
according to learner's speed and ability. Also, they can implement these teaching methods which have been
presented by human mind proficiently i.e., give feedback to learner's errors results in his/her learning. So
Computer software should be presented to different learners.
Computer can expand the size of teaching aid tools [12].It is said that representing feedback to
students in order to make him/her aware of his/her errors in problem solving results in correcting incorrect
knowledge that the student has in his/her mind. Students retain the correct and incorrect information which use
to solve problem in their mind [13]. Seemingly, correcting Student's incorrect mental knowledge through on
time and accurate feedback is an appropriate method for successful and creative students in math education is
important, too. Although, receiving feedback from peers and the teacher can be effective, but the interaction
characteristic of learning environments based on computer facilitates students' self-awareness about
misunderstanding and lack of knowledge among the same-age learners and correct their previous knowledge,
also [14].
Computer feedback kinds are classified as follows:
Knowledge of result (KR) means a kind of feedback which states whether a solution is correct or not?
For strong students, knowledge of possible result is minimum feedback.
Knowledge of correct result (KCR) that present correct solution. This method is suggested for students
with little previous knowledge, low ability, many errors and relative simple learning objectives.
Answer until correct (AUC), asks students try to find correct Answer. This method has been
recognized for students with sufficient abilities to exercise and to do valuable complicated works.
Instruction-based elaboration (IBE) includes an interpretation of correct solution, local errors
correction or representation of main guide [11].

Technological environment are designed purposefully to develop interaction, experiment, further
observation, correction and implementation. Hypothesis are active components which are used to make relation
and improve arguments, therefore, it is necessary to apply proper educational technology according to right
educational principles [3].
This research is going to determine the effect of technology on math learning. The most popular
applied technology in math learning is educational software, so, in this research, NEW GRAPH educational
software that is kind of dynamic interactive software is used as a technological tool. The graph subject of
discrete Mathematics in math undergraduate (that less research is done about educational software technology
in this lesson than other math branches) is taught as a math subject, too. The main hypothesis and question of
this research are as follows:
Hypothesis: the use of NEW GRAPH educational software has effect on students' conceptual
perception.
Question No.1: what kinds of suggestions can be presented for teaching without educational software
according to this research?
Question No.2: whether graph theory is taught by using only educational software or the combination of other
educational methods is necessary?
III. RESEARCH METHODOLOGY
Research method and design: From statistical society of undergraduate students of Mazandaran
teachers' university, one class was selected as an experimental group and the other as a control group. In this
research, available sampling method is used. Independent variable is the use of educational software that is
applied for experimental group. Research design is pretest-post test design with control group (unequal control
group design) [15].
In this research, quantitative and qualitative methods are used. Qualitative method includes interview,
open-answer questionnaire, class observation, study students' journals, study of outlines of graph subject in
discrete mathematics in comparison with the mentioned subjects regarding to this in mathematical principles
and standards book at universities.
Quantitative method indicates covariance analysis of numerical results of written scores average of
lessons that are prerequisites of discrete mathematics and post test scores are related to teach subjects to both
groups after the course.
The researcher made tests consisting of pretest and post test. The content validity of the tests is
confirmed by several math professors and experts. To study the reliability of pretest and post test questions,
these tests are implemented in a class except the control and experiment groups after 20 days. Final coefficients
for pretest and post test are 0.91 and 0.93 respectively.
Implementation: The two groups are taught a graph subject two sessions in a week and for four weeks.
The graph subject of discrete mathematics in undergraduate includes concepts like definition, order, size and
degree of graph, regular, complete and empty graph, road and cycle of graph, connected graph, Oiler and
Hamilton graph, tree and matrix and theorems including "sum of vertices degrees is even", "the number of odd
vertices is even", "there is a direction between every two vertices of a tree precisely" and other theorems and
different definitions. In teaching both groups, it is attempted to use proper educational methods to increase
conceptual perception. The same teaching method has implemented for both groups according to educational
theories.
IV. DISCUSSION AND RESULTS
Result of study and hypothesis of research: The hypothesis of research was "the use of NEW GRAPH
educational software has effect on students' conceptual perception." In order to study hypothesis of research,
covariance analysis method is used. This method studies the effects of one or several independent variables on a
dependent variable and on accompanied variable as an effective variable on dependent variable.

Levin test has shown the homogeneity of variances in both experiment and control group. The
evaluation of balance zero hypothesis between every accompanied variables and independent variable has

shown F related to balance of educational background is not significant (F=0.071, p>0.05), then balance zero
hypothesis is adopted for educational background and independent variable.
Also, F related to pretest scores is not significant (F=0.021, p>o.o5), then zero balance hypothesis of pretest
scores with independent variable is adopted and so covariance analysis is used.
Table 2 .covariance analysis calculations in brief is seen in the table 2,
The significant level of independent variable is equal to 0.015 (p>0.05). Since the significance levels
of educational background score and pretest score are 0.606 and 0.712 respectively and both are more than 0.05,
therefore, these two variables have not much effect on dependent variable (post test scores). It is said that the
two above variables did not affect post test scores and only the use of educational software in experimental
group increased post test scores. Thus, the research hypothesis is confirmed and it can be said that the use of
NEWGRAPH educational software has effect on students' conceptual perception of graph theory.
Answer to research questions: what kinds of suggestions can be presented for teaching without
educational software according to this research? To use technology and its advantages can bring some teaching
strategies to us, if we don't use technology, the ideas are resulted from the use of it can be used. The advantages
of the use of computer in math education which are stated by students are feedback speed and dynamism. Here,
how to combine these advantages in education without using computer is propounded.
Feedback: the advantages if using computer which are mentioned by students in their interviews were
the fast feedback they received from computer. Seemingly, if it is possible to represent sufficient feedback to
students, we can use this advantage of computer without using it in the class. To do this, we can put students
into groups and ask them to give feedback to their friends' errors in problem solving and if they couldn't judge
the solution which is used by them they can depend on teachers. The teacher guides their discussion in order to
prevent them from doing wrong.
If problem solutions are proposed by Seanfeld and Polia is implemented accurately and completely,
correctness or incorrectness of answer can be checked by student himself or herself. For example Seanfeld
considers sources, strategies and control and beliefs systems as necessary aspects of problem solving and
interprets control as a tool to examine the correctness or incorrectness of the applied procedure. Problem
solving steps stated by Polia include problem understanding, planning, plan implementation and regression. In
addition to emphasize control solution in each four steps, Polia states answer in the regression step that
checking is seemed to give feedback to students in each step, especially the last step partially but not as accurate
and fast as computer or even peers and teacher [14,16].
Speed: to consider classes indicates that calculations which have not much effect on understanding the
related problems and subjects are much time consuming. Of course these solutions are not useless completely,
but rather to time spend on them, they are not efficient. This situation has been experienced by researchers in
classes and other professors' discussions who confirm this subject. If there is no computer, we can put students
into groups. In this method, each group can answer a problem and present its result in class which increase
learning in addition to students' learning speed, activities and involvements in groups. Computer is superior to
human because of speed and accuracy in all of its application. We can form an idea of this advantage partially
and reduce students' tiredness of energy consumption for repeating procedures by eliminating unnecessary
calculations in the class.
For instance, drawing forms is one of the problem solutions and at least form an idea to represent a
solution in graph subject. We can present more forms than those are in textbooks currently in order to students
don't spend time on drawing forms or about permutation and combination calculations which are used in graph

subject, we can give some example of solution of this subject to recall what students learnt before and use those
answers that have been prepared before and use calculator.
Dynamism: the form of applied software indicates that students could move created vertices and or
sides easily and observe their changes. Dynamism in research about dynamic geometry software is a proper
method to learn geometric subjects and graph is described as geometry regardless of size. It will use this proper
educational method as dynamic representation. This research results confirm students' deep learning for
teaching graph as a dynamic subject. Those students who have drawn graph by hand and have taught the
transposition of vertices and sides of graph subject have described the graph as more fantastic subject with more
application in addition to learning attractiveness in comparison with the students in control group. Although to
teach graph subject in class dynamically without computer is hard, but we can use dynamic advantage of graph
in teaching. For example, we ask student draw different forms of a graph and state adjacency matrix and other
features students learn graphs with different forms but the same features such as adjacency matrix and the
number of vertices, sides and vertices degrees are considered as one graph.
Whether graph theory is taught by using only educational software or the combination of other
educational methods is necessary?
According to this research result, not only educational software should use to teach, but also other educational
methods like class question and answer, lecture problem solving without computer and other proper methods
should use.
Research results indicate that students' post test scores in experimental group is better from students'
post test scores in control group significantly. Interview with students and class observations clarified that
students could not understand the process solution completely or some of them expect teacher or other
classmates to describe them orally. There are students with different learning styles characteristics in classes.
Huang et al express a kind of grouping students and different learning styles by students:
Independent students prefer educational materials in proportion to their individual speed and study and
tend to individual work rather than work with other students on lesson projects.
Dependent learners consider their teacher and peer as guide authority and prefer an authority tell them how to
solve problems.
Competitive learners try to play role better than their peers and receive confirmation for their educational
knowledge.
Collaborative learners, acquire knowledge through participation and Collaboration.
Avoidant learners do not participate in class activities and discussions motivationally.
Participant learners are interested in class activities and discussions and desired to take part in class
activity as much as possible. They are exited strongly to meet professor's expectation and prefer to give lecture
in small group discussions and group projects.[17]
To use only educational technology without combining with other teaching and learning methods can
not satisfy students with different learning styles and cannot cause their better learning. To use different
teaching methods in class can help student's learning with different abilities.
Give students alone with computer even equipped with most advanced educational software is not a wise
educational method. Human and social communications rule over classes that are expressed under the title of
communication standard in university mathematical principles and standards, it is an important feature that will
be destroyed by using technology only.
The educational materials and subjects, especially social and moral characteristics that are learnt by
students from their peers and teacher never can be substitute by any kind of technology.
It can be said that although computer has features that are necessary in math education, but they are not
useful in this educational research and prevent from class discussion and exchanging views. To use computer,
we should consider it not only as a factor of success but also we should consider educational environments and
the most important thing is their proportion to students' literacy and skill.
Therefore, classes with different educational conditions and students with different educational
backgrounds require different methods to use technology and education and to use technology is not the only
factor of success and if we don't consider other conditions and factors maybe it obstacle other proper
educational methods.
V. CONCLUSION
Speed in proportion to each student's learning and fast learning without using computer and dynamic
mathematical forms which facilitate visualization and make multiple representations of mathematical subjects
possible are the advantages of teaching with software such as feedback and students' interactions with computer.
We should take into account advantages and disadvantages of using technology and try to minimize
disadvantages and emphasize the advantages. In this research, some advantages of a kind of dynamic interaction

are taken into account which is an appropriate technology in math education and some suggestion and strategies
are presented to use and emphasize these advantages while we don't use technology. Researches about using
other technologies in math education will clarify more aspects of technology effects.
