Factors Affecting Failing the Programming Skill Examination of Computing Students
Статья научная
This descriptive study utilized a validated instrument to determine the factors that affect failing a programming skill examination. Through this finding, the study attempted to provide solutions to address the concerns of the students. The top three reasons why students failed the programming skill examination were the insufficient time dedicated to programming courses, self-inefficacy in programming, and unmatched question-time allotment. Overall, respondents attributed their failed mark in programming skill examination to question-related factors. This was confirmed through the use of regression analysis. Hence, it was concluded that students failed the programming skill examination because the perceived ability of the students in the programming skill examination did not correspond with the degree of difficulty of the programming skill examination questions. Further, the null hypothesis stating that student-related concerns do not predict the number of times the programming skill examination would be taken was partially rejected. Hence, it was recommended that the programming skill examination questions be calibrated based on the ability of the students. Future research directions were also presented.

The Malaysian university students faced various obstacles and had unmet needs when it is no longer an option to carry out virtual learning during the COVID-19 pandemic. These challenges faced by students call into question their actual use behaviour and true acceptance of the virtual learning environment (VLE). Thus, this study investigated the students’ actual use behaviour of VLEs, the factors that influence the actual use behaviour, the moderating effect of network connectivity on this relationship, and challenges faced by students while using this technology. The Technology Acceptance Model (TAM) and the Unified Theory Acceptance and Use of Technology 2 (UTAUT2) model were used as the theoretical basis of this study. An online survey was conducted among the International Medical University (IMU) students. The finding surmised that most of the students have adopted the VLE during the pandemic. The findings further revealed that factors such as hedonic motivation, perceived usefulness and perceived ease of use positively affect actual use behaviour, while network connectivity has no significant moderating effect on the relationship between the dimensions of the VLE and actual use behaviour. The key challenges include high cost associated with the VLE usage, and the students find the VLE is not entertaining or enjoyable. These results indicate that students will be inclined to accept the technology if there is high hedonic motivation, perceived usefulness, and perceived ease of use. Universities should focus on enhancing these factors to increase the acceptance of this technology among students, as VLEs have untapped potential for distance learning.

Factors that Impact on Rural and Remote Students’ Participation in Higher Education
Статья
This paper aims to explore the factors that impact on rural and remote students’ participation in higher education at university. The findings indicated that the students were familiar only with university scholarships, tertiary preparation program, and head start. Before admission, most students required information on pathways to university, admission requirements, scholarships, and range of courses and after admission they required information on academic support, tutorial assistance, library and IT services. This paper also suggests that universities need to evaluate the effectiveness of the services they offer to both attract and support rural and remote students to University if participation rates are to be raised.

Fault Repairing Strategy Selector for Service-Oriented Architecture
Статья научная
The success of a service oriented computing significantly depends on its reliability and availability. To achieve better reliability and availability, any fault of the service oriented computing has to be properly handled. Low performance on handling the service fault becomes the most proliferated challenge on fault handling approaches. In this paper, a priority based fault handling strategy selection approach for fault recovery of SOA (Service Oriented Architecture) is proposed using priority selector and fault handler. This approach starts from fault detection method and select the first priority level strategies promptly and if fault could not be handled by first highest level then fault handler selects the second level or intermediate priority level for average performance. As a final in the worst case, least level strategies are applied to resolve the faulty situation. Through experiment, the correctness of the proposed algorithm and the efficiency of the approach are proved. This approach results better performance and high rate of fault repairing.

Fault Tolerant ALU using Parity Preserving Reversible Logic Gates
Статья научная
Demand of reliable computing has been a major concern since the dawn of the electronic digital computer age. Reliable computing has various applications not only in the field of military, aerospace and communication but even contemporary commercial applications to fulfill today's automated life style. The tremendous growth in fabrication from small scale integration (SSI) to giant scale integration (GSI) is facing power dissipation as one of the main barriers. To overcome this barrier, researchers need to enter into the reversible logic domain. Making a reversible circuit robust or fault tolerant is much more difficult than a conventional logic circuit. Fault tolerance can be achieved in a system by using parity bits. The main aim of this paper is to come up with a new fault tolerant ALU design based on parity preserving reversible logic gates with improved quantum cost and power overhead as compare to existing fault tolerance based ALU designs. The most stringent requirement for fault tolerant ALU is in real time control system where faulty computation jeopardizes human life or other catastrophic effects.Implentation of proposed design is done using Xilinx ISE design suit 14.2 tool and its performance over existing ALU designs is qualitatively analyzed.

Favorable Trail Detection using ACO-Bellman Algorithm in VANETs
Статья научная
Vehicular ad hoc networks (VANETs) are the networks, which configured themselves, where the nodes are moving vehicles. These provide the communications required to deploy Intelligent Transportation Systems (ITS). A major dispute in VANETs is distribution of efficient and computable information because during communication nodes may leave or join the network dynamically. There is no guarantee about node availability at any given time, which leads to traffic problem, congestion problem. Therefore trailing the favorable path is a challengeable issue. Multiple routing algorithms have been developed for routing solution. In this paper the swarm-based algorithm has been presented, which helps to find out the optimal route using Bellman Ford algorithm. Ant colonization searches out the path using pheromones level. Higher the pheromone count of a route gives the optimal choice of path that can be used for packet delivery. Bellman Ford Algorithm optimizes the paths found by Ant Colony Optimization (ACO) by comparing the distance of source to all the nodes of network or cost given to the networks.

Статья научная
Teaching and learning Methodologies in technical and engineering education has high impact on attainment of Graduate attributes. Studies have proved that class room teaching with mere usage of Black board (BB) and audio visual presentations doesn't effectively involve the student completely in learning. Also evaluation and assessment with midterm exams and end term exams may not give the complete picture of student learning progress. In fact in today's outcome based education the attainment of course learning outcomes require student centered teaching learning procedures and a continuous evaluation procedure. In this paper Focus question based Inquiry based learning an active teaching learning procedure also student centered is discussed. Also how this method is used for continuous assessment is also explained.

As the English language and information and communication technology (ICT) enhance global interconnection, demands on educating the young generation with English language skills and technological competence increase exponentially. As the successor of education, pre-service English teachers need to be trained with technological pedagogical content knowledge (TPACK). This study aims to develop an instructional model oriented to pre-service English teachers' (PST) TPACK. This is design-based research carried out in three stages: informed exploration, enactment, and evaluation. This study employed a multiphase mixed method. A qualitative design was done in the informed exploration stage, and an explanatory sequential mixed design was used for the evaluation stage. Nine PSTs, three lecturers, and 4 experts were invited as the participants of this study. The qualitative data were analyzed thematically on NVIVO software while the quantitative data were analyzed using descriptive statistic calculation. The results showed that the PSTs need an instructional model that facilitates student agency, learning agency, self-reliance, innovation, and cooperation. An instructional model called Inquiry-based, technology-saturated, and flipped instructional model (INSTALL) was developed. The expert validation result showed that the products of this development study were in the “Very Good” category. The results of the expert judgment indicated that INSTALL could be utilized to enhance the PSTs’ TPACK by blending inquiry-based learning and technology-saturated flipped instruction.

Framework for software code reviews and inspections in a classroom environment
Статья научная
Code reviews and inspections have the purpose to ensure that the code has sufficient quality to be released. It is generally seen as an economical way of finding errors, increase team productivity and sharing technical and product knowledge among team members. This approach is traditionally adopted in software development companies, but their practices may be useful in other contexts, such as in the process of learning software engineering. In this sense, this study proposes an innovative framework for conducting code reviews in a Computer Science course. The proposed framework can be applied in any object-oriented program language, and it is sufficiently concise to be applied in the classroom, namely in a 90-minute session in which all students are invited to collaborate in this process. The findings suggest that code reviews in an academic context can help students to strategically reflect about the performed work, enhance their soft skills, and increase their ability to work in groups. On the other hand, as the main challenges, the findings reveal that students typically don’t have previous experience in performing inspections and it can become difficult to perform a complete inspection in a classroom session.

Free Open Source Software in Electronics Engineering Education: A Survey
Статья научная
Since the last two decades, much attention has been paid to Electronics Engineering (EE) education in India. Various commercial software tools and simulator such as mathematical application packages, electronics CAD tools, learning management systems, multimedia tools and general purpose tools supports EE education. Traditionally, proprietary software packages such as OrCAD Pspice, MATLAB, LabView, Multisim and others too are widely practiced and well integrated in electronics engineering curricula of various Universities nationwide. In today’s market, there are plenty of software tools and packages; however, most of them are expensive. The high cost of standard commercial packages is often hardship for students and faculties. Selecting various appropriate tools for academic use is considered as one of the key challenges in EE education. Over recent years, an alternative trend based on Free Open Source Software (FOSS) has gained momentum in higher education due to several benefits such as cost, license management flexibility, access to source code, security and stability etc. Presently, a plethora of open source software tools and resource related to EE can be deployed in teaching and learning process of EE education. In this communication, a short exposition of Free Open Source Software useful in electronics engineering education and research is presented. A brief outlook of FOSS packages, their web addresses and major highlights are also presented. The overall aim of this paper is to create awareness among instructors and students to impart active and self learning using FOSS.

Clustering of educational data was performed in the space of two parameters using the K-Means method. Students who are characterized by grades in certain types of activities were used as objects of clustering. Software for fuzzy data clustering is implemented in the Python language in the Google Colab cloud service. The obtained clusters are described by fuzzy Gaussian membership functions, which allowed to reliably determine the membership of each object to a certain cluster, even if the clusters do not have clear boundaries. Due to clustering, the most important characteristics of the educational process for a certain task are obtained, that is, this is how Data Manning tasks are solved. Fuzzy membership functions implemented using the scikit-fuzzy library. The developed program can also be used for educational purposes, as it allows a better understanding of the principles of cluster analysis and fuzzy logic. The correctness of the work of the developed program was confirmed during the processing of test educational data. The determination of the number of clusters was performed by software, taking into account the intra-cluster and inter-cluster distances, as well as the shape of the clusters. Automated selection of the number of clusters and cluster boundaries allows to reduce data processing time. The developed clustering tools are designed to increase the efficiency of system analysis of quality education.

Fuzzy Intelligent System for Student Software Project Evaluation
Статья научная
Developing software projects allows students to put knowledge into practice and gain teamwork skills. However, assessing student performance in project-oriented courses poses significant challenges, particularly as class sizes increase. This paper introduces a fuzzy intelligent system designed to evaluate academic software projects using an object-oriented programming and design course as an example. Our methodology involved conducting a survey of student project teams (n=31) and faculty (n=3) to identify key evaluation parameters and their applicable ranges. The critical criteria—clean code, use of inheritance, and functionality—were represented as fuzzy variables with corresponding fuzzy sets. We collaborated with three experts, including one professor and two course instructors, to define a set of fuzzy rules for a fuzzy inference system. This system processes the input criteria to produce a quantifiable measure of project success. Our fuzzy intelligent system demonstrated promising results in automating project evaluation, standardizing assessments, and reducing subjective bias in manual grading. The key findings show that the system effectively manages the increasing instructor workload, provides consistent and transparent evaluations, and offers timely and accurate feedback to students.

Fuzzy Latent Semantic Query Expansion Model for Enhancing Information Retrieval
Статья научная
One natural and successful technique to have retrieved documents that is relevant to users' intention is by expanding the original query with other words that best capture the goal of users. However, no matter the means implored on the clustered document while expanding the user queries, only a concept driven document clustering technique has better capacity to spawn results with conceptual relevance to the users' goal. Therefore, this research extends the Concept Based Thesaurus Network document clustering techniques by using the Latent Semantic Analysis tool to identify the Best Fit Concept Based Document Cluster in the network. The Fuzzy Latent Semantic Query Expansion Model process achieved a better precision and recall rate values on experimentation and evaluations when compared with some existing information retrieval approaches.
