Application Specific Troubleshooting and Problem Solving Tools for the Electrical Engineering Technology Laboratory

Russell A. Aubrey, Thomas A. Zickel Purdue University School of Technology, Anderson, Indiana

Abstract

Several application specific circuit boards and techniques have been designed for use as instructional tools in the Electrical Engineering Technology (EET) laboratory. The primary use of these boards is to serve as an efficient, productive and user friendly platform to introduce electronic circuit problem solving concepts to EET students. Two application specific boards are currently in use. The first is a three-stage transistor amplifier circuit with movable jumpers to configure it into different circuits. The second is a two stage Op-Amp board that allows standard components to be easily configured into Op-Amp circuits for use in the laboratory. These instructional tools provide an opportunity to introduce graphical problem-solving techniques and team concepts into practical student laboratory experiences

This paper describes the circuit boards, the methodology involved in their design and a description of the layout and construction. Laboratory problem solving applications and simulation projects based on these boards are described, and laboratory scenarios are presented.

Introduction

Electronic troubleshooting is a skill that can take a number of years to develop. Mastering this skill is critical for Electrical Engineering Technology (EET) graduates entering the modern workplace. A prime objective of educators is to develop tools and techniques that can significantly shorten this time frame for students with limited electronic experience.

This paper describes instructional tools and techniques developed for use in teaching the troubleshooting course (EET 276) at Purdue University Statewide Technology (PST) sites.

Methodology for the Discrete Amplifier Board

Troubleshooting is typically considered to be an integral part of all EET courses. At Purdue University, EET 276 reinforces the electrical and electronic concepts presented in the first three semesters in EET by presenting actual circuits/systems situations in the laboratory for the student to diagnose and repair. This course is considered to be a capstone course for the two- year EET graduate. The utilization of an application specific transistor amplifier circuit board provides an excellent opportunity to reinforce and apply previously presented circuit techniques.
