Voltmeter Challenge is a set of interactive activities for use in teaching troubleshooting with digital voltmeters. The activities give students immediate feedback to reinforce correct responses. All student responses are corrected and graded by the program. The program can also be used to perform classroom demonstrations using a LCD video projector or large screen monitor. Instructors can lead students through procedures without having to draw circuits on chalkboards or marker boards.

Voltmeter Challenge is easy to use and highly interactive. The program is designed for users who may have little experience with using computers. Voltmeter Challenge allows students to learn by experiment and discovery.

New parameters are selected every time an activity is used. This allows students to practice a particular activity numerous times without becoming bored or memorizing the answers. Because of the simple interface, most students will be able to experimentally learn to use this program within a short time. Most option selections are forgiving because a confirmation is required for important selections.

Progress can be reported to the instructor in three ways. First, students can turn in the program-generated certificates for each topic to the teacher. Second, students can have the program record scores in a file on a diskette to be turned in to the teacher. Third, the teacher can have students perform the computer-based activity on a computer under direct observation.
