Abstract

This paper describes an introductory multimedia lesson on operational amplifiers developed using the ToolBook@ authoring system. The lesson is designed to introduce students to operational amplifiers, their characteristics and several common circuits using operational amplifiers. The lesson is intended to be both theoretical and practical.

Introduction

Operational amplifiers are important electrical circuits. They are used in signal processing, control, and instrumentation circuits. Of all analog integrated devices, the operational amplifier is the most widely used electrical component in a vast variety of electronic circuits. Most electrical engineers will probably encounter more operational amplifiers than any other integrated device. We have developed this lesson to introduce first year electrical engineering students to operational amplifiers and their applications.

Electronic lessons become an effective learning tool for the beginning student when the following features included.

A. The lessons are designed to take the student through the four stages of the Kolb learning cycle: 1) what topics will be learned, 2) why are the topics useful, 3) how can the topics be applied, and 4) asking students “What if?” questions 1’2.

B, The lessons incorporate visual and animated material that show how to construct circuits. Also, the lessons include sound clips demonstrating the effects of clipping at the power supply limits.

C. The lessons are interactive and evaluate student responses. The requested responses are varied and include numerical responses and checklists of possible answers.

D. The lessons can be run individually and repeated by the student at any time.
