DEVELOPMENT AND DEPLOYMENT OF A NETWORK-BASED COMPUTER-ASSISTED LEARNING SYSTEM FOR AN ELECTRONICS LABORATORY
Abstract
The rapid advancement of information and communication technology has significantly transformed teaching and learning processes, particularly in technical and engineering education. This study focuses on the development and deployment of a network-based computer-assisted learning (CAL) system designed to enhance teaching and practical learning activities in an electronics laboratory. The system integrates networked computers, instructional software, and interactive learning resources to support real-time instruction, simulations, assessments, and collaborative learning among students. A modular system architecture was adopted, incorporating a client–server model that enables centralized content management, efficient resource sharing, and effective monitoring of student activities. The development process involved system analysis, design, implementation, and testing phases, using appropriate programming tools and networking technologies. The deployed system was evaluated based on usability, accessibility, instructional effectiveness, and user satisfaction through feedback from students and instructors. Findings indicate that the network-based CAL system improved students’ understanding of electronic concepts, increased engagement during laboratory sessions, and enhanced instructors’ ability to manage and deliver practical lessons effectively. The study concludes that the adoption of network-based computer-assisted learning systems can significantly improve the quality of electronics laboratory instruction and recommends wider implementation in technical and tertiary institutions to promote effective and technology-driven learning environments.
CHAPTER ONE
INTRODUCTION
1.1 Background to the Study
Advancements in information and communication technology (ICT) have significantly transformed teaching and learning processes across educational institutions worldwide. One of the notable developments in this regard is computer-assisted learning (CAL), which integrates computer technologies into instructional delivery to enhance understanding, interactivity, and practical skill acquisition (Alessi & Trollip, 2001). CAL systems provide learners with access to digital resources, simulations, and interactive modules that support both theoretical and practical learning experiences.
In science and engineering disciplines, particularly electronics, effective learning requires a strong balance between theoretical knowledge and hands-on laboratory practice. Traditional electronics laboratories often face challenges such as limited equipment, overcrowding, time constraints, high maintenance costs, and inadequate supervision, which negatively affect students’ learning outcomes (Ajayi & Yusuf, 2018). These challenges are more pronounced in developing countries where funding and infrastructure are limited.
The deployment of a network-based computer-assisted learning system offers a viable solution to these problems. Such systems enable multiple users to access laboratory simulations, instructional materials, and real-time demonstrations over a network, thereby enhancing collaboration, flexibility, and scalability (Kumar & Sharma, 2019). Network-based CAL systems allow students to perform virtual experiments, access electronic circuit simulations, and receive immediate feedback without the constant need for physical laboratory resources.
In an electronics laboratory context, a network-based CAL system can support remote access, resource sharing, instructor monitoring, and automated assessment. This approach not only improves learning efficiency but also promotes independent learning and technological competence among students (Ogunleye, 2020). Consequently, the development and deployment of such systems align with global trends in digital education and smart learning environments.
This study therefore focuses on the development and deployment of a network-based computer-assisted learning system for an electronics laboratory, with the aim of improving practical learning, accessibility, and instructional effectiveness.
1.2 Statement of the Problem
Despite the importance of practical laboratory experience in electronics education, many institutions still rely on traditional laboratory methods that are often inefficient and inadequate. Common problems include insufficient laboratory equipment, limited access time, overcrowded sessions, frequent equipment breakdowns, and high operational costs (Ajayi & Yusuf, 2018). These challenges hinder students’ ability to acquire essential practical skills and negatively impact learning outcomes.
Additionally, conventional laboratory teaching methods offer limited opportunities for individualized learning and real-time feedback. Students often struggle to repeat experiments or practice outside scheduled laboratory hours, which affects mastery of electronic concepts (Kumar & Sharma, 2019). The lack of digital integration also reduces exposure to modern learning technologies required in today’s technology-driven environment.
Although computer-assisted learning systems exist, many are not network-based or specifically designed to meet the needs of electronics laboratories. This creates a gap in the effective use of ICT to support electronics practical instruction. Addressing this gap necessitates the development and deployment of a network-based CAL system tailored for electronics laboratory learning.
