The increase in enrollment in education and higher education institutions, the increase in the use of the Internet as well as the emergence of technology in educational systems have led to the aggregation of large amounts of student data at educational institutions (schools, colleges, and universities), which makes it vital to use data mining methods to improve the educational settings.
Although educational institutions collect an enormous amount of student data, this data is utilized to produce basic insights and is not used for decisions to improve the educational settings.
To get essential benefits from the data, powerful techniques are required to extract the useful knowledge which is valuable and significant for the decision and policy makers.

Data is the Fuel of Organizations: Opportunities and Challenges in AfghanistanAbdul Rahman Sherzad
A car without fuel cannot be driven; a mobile, a laptop or a PC without power cannot be used; a website without feeding won't have any visitors; likewise, an organization without data will not stand and cannot be survived.
The data quickly becoming one of the most important resources for any country, company, or organizations. It is the data that enables organizations to explain the past and guess the future through data science and business intelligence tools.
This presentation demonstrates how the Kankor data can be used as a resource in the context of Afghanistan, particularly, the candidates’ names that organizations in Afghanistan do not use for anything.

Education is one of the main pillars and key concerns for each society in general. In developing countries, in particular in Afghanistan, we observe a remarkable increase in enrollment in education and higher education institutions, but most of the students don't have proper access to their scores. For instance, while Kankor result is announced the vast amounts of traffic the visitors generate make the website completely down and inaccessible. Another example, There is no efficient method to access the university scores in particular for students from other provinces. Last but not least, Diploma and certification verification is a lengthy and complicated process, when graduated students apply for jobs and scholarships inside or outside of Afghanistan they are asked to provide their certificate and diploma. One of the solutions can be verification of the graduation documents through SMS.
In Herat Innovation Lab 2015, Education group members under the mentorship of Abdul Rahman Sherzad chose this social and educational domain problem and within three days they designed and developed a prototype solution that enable students to access i.e. Kankor Scores Result, University Scores Result, Faculties Announcements and Events, and Certificate/Diploma Verification via SMS, Mobile and Web Applications effectively and efficiently.
This paper introduces the competency models for Operations Manager, User Interface
Designer, and Application Developers. It will serve as a guide for Information Systems students
to identify which among the three of the offered tracks would be most suited for them to pursue
according to their knowledge, skills, values and interests. The Holland’s RIASEC model and the
Values Search model of Bronwyn and Holt were utilized to determine the most dominant interest
and most dominant values of the industry computing experts. Survey assessment forms were sent
to IT Operations Manager, User Interface Designer, and Application Developer. Most dominant
values and interests of industry computing experts were determined as well as the knowledge
and skills which are mostly required by the industry in their particular area. Based on the result
of the survey, it shows that application developer and user interface designer have a closely

Data Mining Techniques for School Failure and Dropout SystemKumar Goud
Abstract: Data mining techniques are applied to predict college failure and bum of the student. This is method uses real data on middle-school students for prediction of failure and drop out. It implements white-box classification strategies, like induction rules and decision trees or call trees. Call tree could be a call support tool that uses tree-like graph or a model of call and their possible consequences. A call tree is a flowchart-like structure in which internal node represents a "test" on an attribute. Attribute is the real information of students that is collected from college in middle or pedagogy, each branch represents the outcome of the test and each leaf node represents a class label. The paths from root to leaf represent classification rules and it consists of three kinds of nodes which incorporates call node, likelihood node and finish node. It is specifically used in call analysis. Using this technique to boost their correctness for predicting which students might fail or dropout (idler) by first, using all the accessible attributes next, choosing the most effective attributes. Attribute choice is done by using WEKA tool.

Predicting student performance in higher education using multi-regression modelsTELKOMNIKA JOURNAL
Supporting the goal of higher education to produce graduation who will be a professional leader is a crucial. Most of universities implement intelligent information system (IIS) to support in achieving their vision and mission. One of the features of IIS is student performance prediction. By implementing data mining model in IIS, this feature could precisely predict the student’ grade for their enrolled subjects. Moreover, it can recognize at-risk students and allow top educational management to take educative interventions in order to succeed academically. In this research, multi-regression model was proposed to build model for every student. In our model, learning management system (LMS) activity logs were computed. Based on the testing result on big students datasets, courses, and activities indicates that these models could improve the accuracy of prediction model by over 15%.
Clustering Students of Computer in Terms of Level of ProgrammingEditor IJCATR
Educational data mining (EDM) is one of the applications of data mining. In educational data mining, there are two key domains, i.e. student domain and faculty domain. Different type of research work has been done in both domains.
In existing system the faculty performance has calculated on the basis of two parameters i.e. Student feedback and the result of student in that subject. In existing system we define two approaches one is multiple classifier approach and the other is a single classifier approach and comparing them, for relative evaluation of faculty performance using data mining
Techniques. In multiple classifier approach K-nearest neighbor (KNN) is used in first step and Rule based classification is used in the second step of classification while in single classifier approach only KNN is used in both steps of classification.
But in proposed system, I will analyse the faculty performance using 4 parameters i.e., student complaint about faculty, Student review feedback for faculty, students feedback, and students result etc.
For this proposed system I will be going to use opinion mining technique for analyzing performance of faculty and calculating score of each faculty.
Educational Data Mining is used to predict the future learning behavior of the student. It is still a research topic for the researcher who wants do better result from the prediction of the student. The results of all these techniques help the teachers, management, and administrator to draft new rules and policy for the improvement of the educational standards and hence overall results and student retention. Taking this point in mind work has been done to find the slow learner in a High School class and then provide timely help to them for improving their overall result. There are lots of techniques of data mining are available for use but we are selecting only those techniques which are mostly used by different research for their result prediction like J48, REPTree, Naive Bayes, SMO, Multilayer Perceptron. On the collected dataset Multilayer Perception classification algorithm gives 87.43% accuracy when using whole dataset as training dataset and SMO and J48 gives 69.00% accuracy when using 10-fold cross validation algorithm.
THE USE OF COMPUTER-BASED LEARNING ASSESSMENT FOR PROFESSIONAL COURSES: A STR...IAEME Publication
Background/Objectives: While the increase in classroom technology, it is necessary to examine how assessment is administered through technology. The purpose of this study is to understand how students and faculty are perceived and examine the effectiveness of the computer-based assessment in professional education courses (Educational Technology) at Northern Iloilo Polytechnic State College, Iloilo, Philippines. Methods: The research design utilized in this study is mixed-method research. A computer-based assessment was utilized to assess students' performance in educational technology. This instrument was validated, and pilot tested to establish reliability. Each campus of NIPSC selected ten students of 70 as respondents during Academic Year 2016-2017. Frequency count, mean, standard deviation, and Wilcoxon signed-rank test were statistical tools used for data analyses. Findings: The study's finding showed a high score of students in the posttest ensured better performance of the students in educational technology. The increase in the posttest per performance level of the students was due to an accurate measure of what they have learned in educational technology. The majority of students users agreed that online assessment was fasters than the paper and pencil form. Also, users agreed that online assessment is contemporary and more systematic. They also stated that online assessment is consistent with the teaching style, but they are less anxious. Furthermore, according to faculty and students, ninety percent (90%) believed that computer-based assessment accurately measures what they are teaching and what they learned in school, respectively. Novelty: With the current situation that the education system is in new normal, computer-based learning is important in flexible learning. And assessment using technology is a great help to both faculty and students. Thus, state universities and colleges (SUCs) should adopt this innovation to help teaching and learning.

This paper highlights important issues of higher education system such as predicting student’s academic performance. This is trivial to study predominantly from the point of view of the institutional administration, management, different stakeholder, faculty, students as well as parents. For making analysis on the student data we selected algorithms like Decision Tree, Naive Bayes, Random Forest, PART and Bayes Network with three most important techniques such as 10-fold cross-validation, percentage split (74%) and training set. After performing analysis on different metrics (Time to build Classifier, Mean Absolute Error, Root Mean Squared Error, Relative Absolute Error, Root Relative Squared Error, Precision, Recall, F-Measure, ROC Area) by different data mining algorithm, we are able to find which algorithm is performing better than other on the student dataset in hand, so that we are able to make a guideline for future improvement in student performance in education. According to analysis of student dataset we found that Random Forest algorithm gave the best result as compared to another algorithm with Recall value approximately equal to one. The analysis of different data mini g algorithm gave an in-depth awareness about how these algorithms predict student the performance of different student and enhance their skill.
THE RATIONALE AND FRAMEWORK FOR EVALUATING THE ICT USE IN TEACHER EDUCATION D...DrGavisiddappa Angadi
This study investigated that the quantity of computer and ICT use in teacher education institutions is less and it is mainly focused on the learning of ICT skills which takes optimum time computers are used. The framework is then improved towards a new framework that can be effectively used to evaluate information and communication technology use in pre-service teacher education. In this study the independent variables are derived from computer use within the institution, some other extraneous factor may have impact on the results. Those factors may be computer use at home, friends home and cyber or internet centers by the respondents. The study concludes that the reality rhetoric gap of the impact of ICTs in teacher education institutions be evaluated from periodically to ensure that the quality with program objectives are met. The result shows that there is an urgent need to conduct intensive training to all the teacher educators in the colleges of education. The curriculum developers should develop global content for serving the local needs and make it to available to all the colleges of education online as well as offline content or blended learning modules. Several factors have been cited as responsible for low quantity of computer use in colleges of education. Some of these factors are; attitude towards new technologies, poor management, lack of local content serving local needs, shortage of equipments.
Data mining in higher education university student dropout case studyIJDKP
In this paper, we apply different data mining approaches for the purpose of examining and predicting students’ dropouts through their university programs. For the subject of the study we select a total of 1290 records of computer science students Graduated from ALAQSA University between 2005 and 2011. The
collected data included student study history and transcript for courses taught in the first two years of
computer science major in addition to student GPA , high school average , and class label of (yes ,No) to
indicate whether the student graduated from the chosen major or not. In order to classify and predict
dropout students, different classifiers have been trained on our data sets including Decision Tree (DT),
Naive Bayes (NB). These methods were tested using 10-fold cross validation. The accuracy of DT, and NlB
classifiers were 98.14% and 96.86% respectively. The study also includes discovering hidden relationships
between student dropout status and enrolment persistence by mining a frequent cases using FP-growth
algorithm.
This study aims to examine factors influencing aspects such as teacher's personality, student's behavior, environmental which has influence student's affective and cognitive. The data were obtained using methods: interview and questionnaire. The random participant has been chosen for interviewed and population has been used for the questionnaire.

This presentation explains and solves problems such as Factorial, Fibonacci, Greatest Common Divisor, Binary Search, and Traversing Directory and Sub-Directories in both recursion and iteration.
In summary, there are similarities between recursion and iteration. Hence, any problems that can be solved with iterations can be solved with recursions and vice versa.
In SQL, the ORDER BY keyword is used to sort the result-set in ascending (ASC) or descending (DESC) order by some specified column/columns.
It works great for most of the cases. However, for alphanumeric data, it may not return the result-set that you will be expecting.
This presentation explains how this can be addressed using different techniques.
In PHP, variable variables take the value of one variable, and treat that as the name of another variable.
Variable variables are just variables whose names can be programmatically set and accessed. Hence, they are also called dynamic variable names.
Cross joins are used to return every combination of rows from two and more than two tables. Cross Joins are sometimes called a Cartesian product. This presentation illustrates cross join examples and applications in real life.
Secure web programming plus end users' awareness are the last line of defense against attacks targeted at the corporate systems, particularly web applications, in the era of world-wide web.
Most web application attacks occur through Cross Site Scripting (XSS), and SQL Injection. On the other hand, most web application vulnerabilities arise from weak coding with failure to properly validate users' input, and failure to properly sanitize output while displaying the data to the visitors.
The literature also confirms the following web application weaknesses in 2010: 26% improper output handling, 22% improper input handling, and 15% insufficient authentication, and others.

Database Automation with MySQL Triggers and Event SchedulersAbdul Rahman Sherzad
This advanced training seminar on "Database Automation using MySQL Triggers and Event Schedulers" is dedicated to the Computer Science graduates and students of both public and private universities.
In this seminar we are going to look in depth at MySQL Triggers and Event Schedulers– powerful features supported by most popular commercial and open source relational database systems.
The Triggers are powerful tools for protecting the integrity of the data in the databases, logging and auditing of the changes on data, business logic, perform calculations, run further SQL commands, etc.
The Events are very useful to automate some database operations such as optimizing database tables, cleaning up logs, archiving data, or generate complex reports during off-peak time, etc.
The participants will learn about the true concept, implementation and application of MySQL Triggers and Event Schedulers with real life examples and scenarios.
They will also learn how to use the database triggers and event schedulers in many real cases to automate database tasks - such as optimizing database tables, cleaning up logs, archiving data, or generate complex reports during off-peak time.
This seminar is presented by Abdul Rahman Sherzad lecturer at Computer Science faculty of Herat University, and PhD Student at Technical University of Berlin, Germany at Hariwa Institute of Higher Education, Herat, Afghanistan.
Innovation Labs (iLabs) is a social innovation program covering a series of conferences. One the one hand, the goal is to bring social and technology experts together for the networking purpose. On the other hand, the motivation is to harness technology to solve the most challenging social and environmental problems and to build tech-based systems.
This presentation looks into the existing web structure and services of all Afghan universities, not only to evaluate the entire infrastructure but also to systematically analyze the gaps and design challenges of web platforms and services as a means of communication and collaboration among various stakeholders including the Ministry of Higher Education, its subsidiaries, students and other related audience.
The presentation finds that the environment for necessary ICT infrastructure and services is up to the expected required standard to provide access to various online resources and systems. The next important finding is the increasing demand by students to access information online rather than the existing traditional paper-based systems. Another very important finding is related to the non-existence of a formal managerial oversight to all the online resources and thus has resulted to a very poor quality of content, outdated information and the services that don't meet the expected needs and challenges.

In addition, Virtual Keyboard used for the following subjects: Foreign Character Sets, Touchscreen, Bypass Key Loggers, etc.
With Unicode you can program and accomplish many funny, cool and useful programs and tools as for instance, Abjad Calculator, Bubble Text Generator to write letters in circle, Flip Text Generator to write letters upside down, Google Transliteration to convert English names to Persian/Arabic, etc...
This presentation explores and discusses the practical and useful of Regular Expressions covering username validation, complex and strong password validation, password strength checker, email validation, and finally image file extension validation.
Regular Expressions (Regex) is powerful and convenient to use for string manipulation i.e. matching and validation, extracting and capturing, modifying and substitution, etc. This presentation covers Regular Expression with real world examples and demos.
All in all, Regular Expression is worth learning!!!
Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.

6. Educational Data Mining
It is an emerging discipline to develop methods for
exploring the data that come from educational
settings to better understand students and the
settings which they learn in.
6
7. EMD Application
EDM is useful in many different areas including
• Providing feedback for supporting instructors,
• Detecting undesirable student behaviors,
• identifying at-risk students,
• increasing graduation rates,
• effectively evaluating institutional performance,
• recommending the right courses for the students,
• and helping students in Major selection.

8. 1. Does Afghanistan
Education Systems
need EMD?
In the context of Afghanistan,
◦ there are large amounts of data
available for mining purposes in the
education domain,
◦ but the methods that the educational
institutions use to store and produce
their data only enable them to achieve
basic insights.
2. What are the EDM
Applicability in
Afghanistan
Education Systems?

NOTE: The above-mentioned calculations indicate (only) marks data. Of course there are
different entities exist in the university and school systems i.e. teachers, students, students
dependents, subjects, activities, classes, etc.
Public High school students facts
# of students years of study # of subjects (average) exams (mid and final) Total Records
~ 1,000,000 3 15 2 90,000,000
Public High school graduates/year facts
# of students years of study # of subjects (average) exams (mid and final) Total Records
~ 200,000 3 15 2 18,000,000
10. Storage of schools data in Afghanistan (scenario)

# of students Storage/student Total Storage (MB) Total Storage (GB) Total Storage (TB)
~ 1,000,000 2 MB 2,000,000 MB 2,000 GB 2 TB
11. The Problem
Inappropriate choice of Major
◦ students are not offered
specialized studies at high
schools,
◦ family literacy rates are low so
parents cannot help students
with choosing a career,
◦ high schools lack basic career
counseling services,
◦ and there are no academic
advisory organizations outside
educational institutions to
guide the students on this
critical career decision.
11
NOTE: The data shows one-third of the students admitted into Herat
public university could not continue higher education studies!
12. EDM Application I:
Major prediction
12
In Afghanistan, there are no academic advisory
organizations to guide the Kankor candidates on
choosing proper fields of study.
• Design a classification model to predict/recommend proper
Major to high school graduates prior attending the Kankor.
In Afghanistan, students are not offered specialized
studies.
• Design a learning model to automate student placement into
sciences or social sciences while specialized studies is offered at
school level.
13. EDM Application II:
Support student at
risk of attrition and
failure
13
In Afghanistan, most of the students have no
knowledge of the requirements and
prerequisites of the offered fields of study,
and select randomly.
◦ The results are poor performance or high rates
of dropout in higher education.
14. Challenges prevent the applicability
of EDM in Afghanistan
• Lack of data availability and accessibility!
• Lack of experts in the domain of Data Mining and
Educational Data Mining!
