One of a set of presentations describing the behavior of semiconductor devices. This applet shows how the base of a BJT behaves under a variable set of conditions. It provides EE students with the ability to interact with a working model of the BJT base behavior.
Type of Material:
Tutorial with simulation, visulaization, problem solving and review test.
Supplement class lectures and text
Java enabled browser
Identify Major Learning Goals:
Understanding one aspect of basic BJT behavior. The student should be able to describe the effect variations in the base electrical and semiconductor parameters.
Target Student Population:
2nd & 3rd year EE & ECE students
Prerequisite Knowledge or Skills:
Understanding of basic microelectronics behavior. Some circuit analysis.
Evaluation and Observation
Provides visualization, simulation, exercises, etc. The material is generally part of the core curriculum in Electrical/Computer Engineering. The graphics are attractive and get the user's attention.
Some portions of the presentaion are incomplete, but the presentation is still very usable.
Potential Effectiveness as a Teaching Tool
Good supplement to text & lecture; provides opportunities for students to explore. The material can be easily incorporated into homework assignments, group assignments, and in a tuterial fashion.
Students must review written material before they simply start clicking on applet. Initial guidance must be provided by an instructor.
Ease of Use for Both Students and Faculty
Software is robust and easy to use.
A teacher's manual could assist instructors in choosing how to use the material effectively.
Other Issues and Comments:
This applet should help students better understand the topic. It offers opportunities for visual learners, drill and practice, explorations, and skill testing
