It summarizes key aspects of van Hiele's theory, including the 5 levels of geometric thinking and 5 levels of study. The proposed courseware aims to assess students' current visualization level, provide level-appropriate content through games and activities, and improve students' spatial reasoning abilities. Details are provided about how the courseware interface was developed, including login procedures, a main menu, and rooms targeting different skills.
Assessing Elementary Pre-service Teachers' Knowledge for Teaching Geometryinventionjournals
Invoking the first three van Hiele levels of geometric thought, pre-service elementary teachers (N = 52) were assessed on their content and pedagogical geometry knowledge as well as their spatial visualization skills. The pre-service teachers’ first and second level responses to the geometry test items indicated a severe deficit in their geometric understanding. By not demonstrating geometric thought at the third van Hiele level, these teachers lacked the skills to competently teach students in grades 1 through 8.
Conceptions and Reasonings of Beninese Learners in Solving Physics Problems I...inventionjournals
In this work, we describe the modes of reasoning of the learners in order to resolve two types of problems and involving the object "acceleration" in a scientific context and the object "rapidity" in an empirical context or everyday life. These learners are young Beninese students with a scientific G.C.E.A.Level and who have been trained according to the competency approach by qualified teachers with at least five years of experience and with course materials authorized by the inspection directorate education and secondary education. From the different analyzes (lexical and sequential), it emerges that in the resolution of these problems, the concepts, rules and formulas mobilized by these learners appear as concepts and theorems-in-act (Vergnaud, 1994) Categorized profiles and according to the contexts of investigation. Different modes of reasoning stem from their distances from the design intended for the object of investigation. If, according to Rey, Defrance and Kahn (2006) and Carette (2009), reasonings and conceptions are indispensable to be competent, it seems to us that the didactic choices prescribed by the actors of the Beninese education system in the implementation of this new approach will allow Difficult to achieve the objectives of the change of approach.

The study aimed at investigating the levels of geometrical thinking among students receiving blended learning in Jordan. The study sample consisted of (104) students/teachers of open education systems in Jordan for the 2015-2016 academic year. In order to answer the questions of study, the researcher developed a scale of geometric thinking, it is validity and reliability has been verified. The results of the study showed a low level of geometrical thinking among students receiving blended learning. The percentage of students in the first level (visual) (51%), the percentage of students in the second level (descriptive) (15%), and the percentage of students in the third level (logical) (3%). Also it showed differences in the levels of geometric thinking between males and females in favor of males, as well as differences in the level of geometrical thinking between students from the scientific stream and students from the literary stream in favor of scientific stream. In the light of the results of the study, the researcher recommends that pre-service teachers should be trained on programs contains geometrical thinking at open learning universities.

The aim of this study was to determine whether Van Hiele’s 5 phase-based tangrams activities could help to foster creativity among Grade Three primary school students.
This document discusses a study that examined whether the poor English proficiency of English second language (ESL) teacher students affected the progress of ESL learners during support lessons. The study analyzed errors in portfolios of teacher students enrolled in an Advanced Certificate in Education program at the University of South Africa. The results showed similarities between the errors of teacher students and learners, suggesting the teachers' limited English skills may have negatively impacted learners' English acquisition. However, the document notes other factors could also influence learners and more research is needed.
Making scientific concepts explicit through explanations simulations of a hig...Lazar Stosic
There is a current research interest into high-leverage teaching practices which are geared towards making concepts explicit to learners. Explanations are a common practice in science education for sharing and constructing meaning with students. However, current studies insufficiently articulate a framework for understanding pre-service teachers’ explanations; neither do they assess the practical criteria for development. This article documents various criteria for pre-service science teachers’ explanations as related to the cognitive science literature and their assessment in the context of an instrument designed for teacher education. A rubric was constructed which organized structural and supportive elements into three levels. A validation process is described, and its application in teacher education programs to detect possible patterns and changes in pre-service science teachers’ explanations. The results show the explanation strengths of pre-service teachers working with examples, graphs and images. However, difficulties were found in using and improving analogies, metaphors, and models, and also approaching mis-conceptions as a learning opportunity. Theoretical and practical issues are discussed from a cognitive perspective. We conclude that the signaling implications of using rubrics sensitive to progress-monitoring during teacher education for high-leverage teaching practices give opportunities to simulate and rehearse practices that are highly conducive to learning.

A scenario based learning of electrical circuitsAlexander Decker
This document presents a framework for teaching electrical circuits using scenario-based learning. The framework consists of 5 activities where student teams use simulation software to explore series, parallel, and combination circuits. Through guided discovery and discussion, students learn the concepts of voltage, current, and resistance in different circuit types. The goal is for students to develop problem-solving skills and gain a conceptual understanding of electrical principles. Assessment involves discussion as students compare their predictions and findings. The scenario is designed using constructivist and cooperative learning principles to actively engage students in building knowledge through hands-on exploration and peer collaboration.
This document discusses frameworks for children's mathematical thinking and the importance of experiences in developing conceptual understanding of mathematics. It argues that experiences should illustrate concepts in multiple contexts to build representations and connections. Concrete materials can help students understand concepts but must be closely linked to the intended concept. The teacher's role is to provide engaging experiences that emphasize conceptual understanding and a positive attitude towards math.
This document summarizes research on how students' level of interest and enjoyment in a topic impacts their approach to learning. The research found that students were more likely to adopt a deep approach, actively trying to understand the material, when they had a high level of interest and enjoyment in the topic. Conversely, students tended to take a surface approach, focusing only on memorization, when they had little interest or enjoyment. While previous research established that assessment requirements influence a student's approach, this study suggests interest and enjoyment are also important factors that can determine whether a student utilizes a deep or surface learning approach. The findings highlight the need for educators to consider how to engage student interest in order to encourage deep learning.
This document describes best practices in technical education used at Mount Zion College of Engineering & Technology. It discusses how the college uses Bloom's revised taxonomy as a framework to develop specific, measurable learning objectives aligned with cognitive levels and knowledge dimensions. Teachers create lesson plans and learning activities mapped to the taxonomy to systematically facilitate student learning. Assessment is also designed based on the taxonomy to evaluate if students achieved the objectives. The methods section provides an example mapping of an objective, activities, and assessment to the taxonomy table to illustrate how it ensures proper alignment of the educational components.
The document proposes an adaptive e-learning system based on learner's learning styles diversity. It discusses motivations for such a system given individual differences in learning styles. The research methodology involves studying learning styles models like MBTI, developing a model with adaptation features, and conducting a case study to analyze learner preferences. The proposed system would adapt course presentation and materials to match a learner's personality type as identified by the MBTI model.
This document discusses approaches to mathematics curriculum as suggested by the National Curriculum Framework (NCF) and Kerala Curriculum Framework (KCF). It outlines three levels of mathematics taught in schools: daily life calculations, concepts for higher education, and more complex theoretical ideas. The document also examines why students find mathematics difficult and why it is important to learn. It proposes teaching mathematics in a way that makes it enjoyable and helps students think logically and communicate numerically. The goal is for students to understand fundamental concepts and have confidence in their mathematical abilities.
This document presents a thesis that examines the correlation between pupils' interest, study habits, and their achievement in mathematics. It begins with an introduction that establishes the importance of mathematics and discusses the Philippines' poor performance in international mathematics assessments. The theoretical framework discusses theories related to mathematics learning and motivation. The study aims to determine the relationship between pupils' interest, study habits, and their mathematics achievement. It will survey grade 4-6 pupils to understand their levels of interest, study habits, and mathematics achievement. The study seeks to provide insights to help improve mathematics performance and education quality.

This study investigated gender differences in mathematics performance among dyslexic and dyscalculic learners in junior secondary schools in Sokoto State, Nigeria. A sample of 827 students, including 423 males and 404 females, was given pre- and post-tests to measure mathematics achievement before and after a 12-week remedial instruction program. The results showed that the experimental groups who received the remedial instruction improved their mean test scores by 54.49%, while the control groups who did not receive the instruction only improved by 0.3%. The findings indicated that the remedial program was effective for dyslexic and dyscalculic students and that there was no significant gender difference in academic performance on the pre
This document discusses a study that examined the effects of an Experiential Cooperative Concept Mapping (ECCM) instructional approach on secondary school students' motivation to learn physics in Nyeri County, Kenya. The study used a quasi-experimental research design involving 513 students from 12 schools. Students in the experimental groups were taught using ECCM, while the control groups used Regular Teaching Methods. Results from pre- and post-tests using a Student Motivation Questionnaire found that students taught with ECCM had significantly higher motivation to learn physics compared to those taught with regular methods. The researchers recommend using ECCM to address low student motivation in physics.
The document discusses the importance of setting goals for small business success. It states that having a clear vision and goals is essential, as less than 1% of adults have clearly stated goals yet those who do earn up to 10 times more. It recommends business owners first develop a vision for their desired future business size and offerings. They should then set specific, measurable goals to achieve that vision, and break big goals into smaller, weekly or daily tasks. Having accountability partners and visualizing success daily can help goal achievement.

The Management Operation System Technique (MOST) invented in 1961, replaces PERT and
CPM on construction projects and in program management. Since its inception, MOST has gained
popularity and is now widely used in both large and small construction projects. Its use has been
equally effective on projects ranging from several thousand dollars to $193 million so far. It is a
combination of several traditional and modern planning techniques like bar chart, Gantt chart, CPM
and PERT. The advantages of these have been extracted and disadvantages have been eliminated. Few
of the advantages are: it is very helpful for repetitive works in both real and infrastructure projects and
uses backward integration which helps in knowing the ground realities very easily. It gives the project
manager visibility and identifies potential trouble areas requiring management action. This paper deals
with application of MOST for construction activities of a 25 Kms Road project and drawing of MOST
schedules. In the end the limitations of MOST are mentioned
Comparing: Routing Protocols on Basis of sleep modeIJMER
The architecture of ad hoc wireless network consists of mobile nodes for communication
without the use of fixed-position routers. The communication between them takes place without
centralized control. Routing is a very crucial issue, so to deal with this routing algorithms must deliver
the packet in significant delay. There are different protocols for handling the mobile environment like
AODV, DSR and OLSR. But this paper will focus on performance of AODV and OLSR routing protocols.
The performance of these protocols is analyzed on two metrics: time and throughput
GPS cycle slips detection and repair through various signal combinationsIJMER
This document discusses methods for detecting and repairing GPS cycle slips. It examines using various combinations of GPS signals as test quantities for detection, including carrier phase observations alone and in combination with pseudorange observations. It finds that graphical detection works for larger slips but statistical tests are superior for detecting smaller slips. For repairing slips, it evaluates using time differences of the original carrier phases and finds that all methods can be used except averaging all data for the first and second differences due to low accuracy. The overall goal is to detect and repair cycle slips to improve positioning accuracy from carrier phase observations.
Implementation of High Throughput Radix-16 FFT ProcessorIJMER
The extension of radix-4 algorithm to radix-16 to achieve the high throughput of 2.59 giga-samples/s for WPAN’s.We are also reformulating radix-16 algorithm to achieve low-complexity and
low area cost and high performance. Radix-16 FFT is obtained by cascaded the radix -4 butterfly
units. It facilitates low-complexity realization of radix-16 butterfly operation and high operation speed
due to its optimized pipelined structure. Besides, a new three-stage multiplier for twiddle factor
multiplication is also proposed, which has lower area and power consumption than conventional
complex multipliers
Stress Analysis of Precast Prestressed Concrete Beams during LiftingIJMER
The use of long span prestressed beams in bridge construction is very common. Even if the
sections are economical the erection of the beam still poses a challenge in construction. Not much work
has been done in the analysis of stress and deflection at erection stage. This paper deals with the
behavior of precast prestressed beams during lifting. Since the spans of these beams are large, it may
fail due to cracking during erection. In this paper a detailed 3-dimensional Finite Element Analysis of 2
prestressed beam sections was done with incorporating the effect of initial imperfections and prestress.
Results were obtained for both prestressed beam and non-prestressed beam and were compared with
Moen’s formulae. To include the effect of prestressing cables in the beam new additional formulae were
introduced and used in combination with the Moen’s. The results obtained were approximately validated
with the Finite Element Analysis results. It is seen that the prestressing cables have a significant effect
on the behavior of a beam during lifting. For a prestressed beam the overhang length should be kept
minimum for safe erection which is opposite in the case of a normal beam.
Hybrid Photovoltaic and thermoelectric systems more effectively converts solar energy into electrical energy. Two sources of energy are used one of the energy is solar,that converts radiant light into electrical energy and heat energy which will convert heat into electricity.Photovoltaic cells and thermoelectric modules are used to capture and convert the energy into electricity.Furthermore solar-thermoelectric hybrid system is environmental friendly and has no harmful emissions.Solar-thermoelectric hybrid system increases the overall reliability without sacrificing the quality of power generated.In this paper an overview of the previous research and development of technological advancement in the solar-thermoelectric hybrid systems is presented.
The document proposes and analyzes a two-layer photonic crystal fiber with a Borosilicate crown glass core and different air hole diameters in the inner and outer cladding layers to achieve a flat chromatic dispersion. Simulations using the scalar effective index method show that the proposed Borosilicate crown glass fiber can achieve nearly zero and flat dispersion across a wide wavelength range, comparable to silica-based photonic crystal fibers. Key parameters varied in the simulations include the inner and outer cladding air hole diameters and pitch to optimize the dispersion characteristics.
The document proposes a new optimized design for a binary coded decimal (BCD) adder using reversible logic gates. It summarizes the basic definitions of reversible logic and describes commonly used reversible gates like CNOT, Toffoli, Peres, TR, and MTSG gates. It then presents the conventional design of a BCD adder and proposes a new design using MTSG gates that has lower quantum cost, fewer gates, and less delay compared to existing designs. The proposed 4-bit reversible BCD adder requires only 10 gates and has a quantum cost of 40.
Implementation of Wide Band Frequency Synthesizer Base on DFS (Digital Frequ...IJMER
Wide Band Frequency Synthesizer has become essential components in wireless communication
systems. They are used as frequency synthesizers with precise and convenient digital control in both traditional
electronics, such as televisions and AM/FM radios, and modern consumer products among which cellular
mobile phone is a striking example.
IC fabrication technology advances have made monolithic integration possible. More and more
electronic devices can be put on the same chip to reduce the number of external components and then the costs.
Therefore, on a single chip we can accomplish many functions for which we might need to make several chips
work together a few years ago. A monolithic wide-band PLL is of great interests to wireless communication
applications due to both its low cost and convenience to switch between different communication standards.
The focus of this work is to implement a wide-band Frequency Synthesizer using as few as possible building
blocks and also as simple as possible structure.
This document summarizes a journal article about using wireless sensor networks in intelligent transportation systems. It discusses how wireless sensor networks can be used to obtain information about traffic conditions from spatially distributed sensors. This allows for more effective management of traffic. It then provides details about the design of sensor nodes, including subsystems for data collection, processing, communication, and power. Sensor nodes are designed to balance requirements like processing power, low power consumption, cost, and security. Wireless sensor networks have potential applications in monitoring traffic flow, parking lots, and traffic intersections.

Geochemistry and Genesis of Kammatturu Iron Ores of Devagiri Formation, Sandu...IJMER
The Greenstone belts of Karnataka are enriched in BIFs in Dharwar craton, where Iron
formations are confined to the basin shelf, clearly separated from the deeper-water iron formation that
accumulated at the basin margin and flanking the marine basin. Geochemical data procured in terms of
major, trace and REE are plotted in various diagrams to interpret the genesis of BIFs. Al2O3, Fe2O3 (T),
TiO2, CaO, and SiO2 abundances and ratios show a wide variation. Ni, Co, Zr, Sc, V, Rb, Sr, U, Th,
ΣREE, La, Ce and Eu anomalies and their binary relationships indicate that wherever the terrigenous
component has increased, the concentration of elements of felsic such as Zr and Hf has gone up. Elevated
concentrations of Ni, Co and Sc are contributed by chlorite and other components characteristic of basic
volcanic debris. The data suggest that these formations were generated by chemical and clastic

Non linear analysis of Robot Gun Support Structure using Equivalent Dynamic A...IJMER
Robot guns are being increasingly employed in automotive manufacturing to replace
risky jobs and also to increase productivity. Using a single robot for a single operation proves to be
expensive. Hence for cost optimization, multiple guns are mounted on a single robot and multiple
operations are performed. Robot Gun structure is an efficient way in which multiple welds can be done
simultaneously. However mounting several weld guns on a single structure induces a variety of
dynamic loads, especially during movement of the robot arm as it maneuvers to reach the weld
locations. The primary idea employed in this paper, is to model those dynamic loads as equivalent G
force loads in FEA. This approach will be on the conservative side, and will be saving time and
subsequently cost efficient. The approach of the paper is towards creating a standard operating
procedure when it comes to analysis of such structures, with emphasis on deploying various technical
aspects of FEA such as Non Linear Geometry, Multipoint Constraint Contact Algorithm, Multizone
meshing .

Material Parameter and Effect of Thermal Load on Functionally Graded CylindersIJMER
The present study investigates the creep in a thick-walled composite cylinders made
up of aluminum/aluminum alloy matrix and reinforced with silicon carbide particles. The distribution
of SiCp is assumed to be either uniform or decreasing linearly from the inner to the outer radius of
the cylinder. The creep behavior of the cylinder has been described by threshold stress based creep
law with a stress exponent of 5. The composite cylinders are subjected to internal pressure which is
applied gradually and steady state condition of stress is assumed. The creep parameters required to
be used in creep law, are extracted by conducting regression analysis on the available experimental
results. The mathematical models have been developed to describe steady state creep in the composite
cylinder by using von-Mises criterion. Regression analysis is used to obtain the creep parameters
required in the study. The basic equilibrium equation of the cylinder and other constitutive equations
have been solved to obtain creep stresses in the cylinder. The effect of varying particle size, particle
content and temperature on the stresses in the composite cylinder has been analyzed. The study
revealed that the stress distributions in the cylinder do not vary significantly for various combinations
of particle size, particle content and operating temperature except for slight variation observed for
varying particle content. Functionally Graded Materials (FGMs) emerged and led to the development
of superior heat resistant materials.

How does your privacy program stack up against your peers? What challenges are privacy teams tackling and prioritizing in 2024?
In the fifth annual Global Privacy Benchmarks Survey, we asked over 1,800 global privacy professionals and business executives to share their perspectives on the current state of privacy inside and outside of their organizations. This year’s report focused on emerging areas of importance for privacy and compliance professionals, including considerations and implications of Artificial Intelligence (AI) technologies, building brand trust, and different approaches for achieving higher privacy competence scores.
See how organizational priorities and strategic approaches to data security and privacy are evolving around the globe.
This webinar will review:
- The top 10 privacy insights from the fifth annual Global Privacy Benchmarks Survey
- The top challenges for privacy leaders, practitioners, and organizations in 2024

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
Cosa hanno in comune un mattoncino Lego e la backdoor XZ?Speck&Tech
ABSTRACT: A prima vista, un mattoncino Lego e la backdoor XZ potrebbero avere in comune il fatto di essere entrambi blocchi di costruzione, o dipendenze di progetti creativi e software. La realtà è che un mattoncino Lego e il caso della backdoor XZ hanno molto di più di tutto ciò in comune.

the passwords to rooms that are appropriate to their levels. Explanations for each game are as follows.
As displayed in Fig. 5, „Find the same Shape‟ is a
game that provides cards with objects that can be seen in
the surroundings and the learner must find the same shape.
When learners see a notebook, they search for a rectangular
shape. If the learners see a mountain or shellfish, they
search for a triangular shape. If they see a ball, they will
recognize it as a circular shape. Thus, learners are tested on
their ability to distinguish between different shapes.

2.3 Diagnosis of the Learner’s Level
As shown in Fig. 3, a level test is presented with
20 questions; and, when the presented numbers are clicked,
the next question is presented. When the correct answer is
clicked, the score increases. The level of the learner is
decided depending on this score.
Fig. 5 Find the same Shape Game
As displayed in Fig. 6, „Capture the Shape‟ is a
game where shapes have to be recognized although the
cards have been divided into upper and lower parts and
moved from left to right during a short amount of time. In
this game, as the shapes pass by, the learners have to guess
the shapes. This, then, contributes to helping learners
visually recognize various shapes.

As shown in Fig. 4, depending on the diagnostic
test results, passwords that can take learners to the Room of
