This is the summary of a presentation given at the Joint Mathematics Meetings, January 10-13, 1996, Orlando, Florida.

During the past three years we have been teaching linear algebra as a laboratory course using an interactive text we have authored in Mathcad. The goal of the text is to improve long range retention of the subject matter and problem solving skills. Students actively participate to develop a concept, connect it to preceding ideas, experiment with its properties, and use it in applications. This format emphasizes reading, talking (we encourage collaborative learning in pairs), writing, and connection of topics.

The role of the student has changed from passive to active and the role of the instructor has changed from a direct presenter to a consultant on an individualized basis. An initial period is required for the students to adjust to the discovery based style, the software, and the increased responsibility. The lab format requires more time for the student (and for the instructor) than the traditional course. Student attitudes have been, on the whole, positive.
