TL;DR

This paper proposes the Electronic Mini-Lab (EML), a low-cost, portable hands-on learning tool integrating basic electronic components, ICs, wires, and a battery for independent student use. By enabling anytime, anywhere practical work in digital and analog circuits and project prototyping, the EML enhances student engagement, confidence, and technical skills while reducing strain on institutional labs, demonstrating significant pedagogical benefits in technical education.

ABSTRACT

-- In this paper, a new approach to impart practical skill based technical education is presented in comprehensive manner. An Electronic Mini-Lab (EML) is devised containing basic design and test instruments with electronic components, ICs, connecting wires and battery. Using the EML, students perform various formal and informal digital and analog circuit practicals as well as design prototype of projects. This gives them a hands-on experience, sense of belonging and sense of cooperation. The EML is useful for performing many practicals of various subjects. The EML also reduces the workload of college laboratories. Students have their own individual EML at their disposal anytime, which can be used to design hobby projects as a fun too. This will make them skilled engineers. This provides tremendous benefits in teaching learning process. It also boosted the interest, confidence of students and teachers. Incorporating active/ cooperative learning into traditional instruction can be a useful pedagogical tool to help students to perform practicals and project work any time anywhere. This concept is remarkably simple and cost effective but the dividends can be profound.

Motivation & Objective

• To address the limitations of traditional, centralized college laboratories in providing consistent, accessible hands-on experience in technical education.
• To reduce the workload on institutional labs by enabling individual student access to practical learning tools.
• To foster student engagement, confidence, and cooperative learning through continuous, self-paced experimentation.
• To develop a scalable, low-cost solution for practical skill acquisition in digital and analog electronics.

Proposed method

• Design and fabrication of a compact, self-contained Electronic Mini-Lab (EML) with essential components including ICs, resistors, capacitors, wires, and a battery.
• Incorporation of basic design and testing instruments within the EML to support circuit construction and verification.
• Deployment of the EML in a case study setting for formal and informal practicals across multiple technical subjects.
• Encouragement of student-led project prototyping and hobby-based experimentation to reinforce learning.
• Integration of active and cooperative learning models into traditional instruction through individual EML ownership.
• Use of the EML to support anytime, anywhere learning, reducing dependency on scheduled lab sessions.

Experimental results

Research questions

• RQ1 How does individual access to a portable EML impact student engagement in practical electronics education?
• RQ2 To what extent does the EML reduce the burden on centralized college laboratories?
• RQ3 What is the effect of hands-on, self-paced experimentation using EML on student confidence and technical skill development?
• RQ4 Can the EML effectively support both formal curricular practicals and informal project-based learning?
• RQ5 How does the EML contribute to cooperative and active learning in technical education?

Key findings

• The EML significantly reduced the workload on college laboratories by enabling individual, off-schedule experimentation.
• Students developed stronger technical skills through repeated, hands-on practice with real components and circuit design.
• The EML facilitated both formal practicals and informal hobby project development, enhancing creativity and ownership.
• Teachers observed improved student participation and a more cooperative learning environment during lab sessions.
• The low-cost, portable EML model proved effective and scalable for widespread adoption in technical education.
