Acknowledgments
The labbased approach described here builds upon insights, projects, and
collaborations with many others at Grinnell College:

Original labbased work, in context of linear algebra:
Eugene Herman

Conversations with colleagues:
John Stone, Sam Rebelsky, Janet Davis, Jerod Weinman, Marge Coahran (later
at Dickinson College, U. of Toronto, and software development)

Examination of literature:
Kevin Engel, Paul Hutchinson
Experiments with Linear Algebra at Grinnell College
Through the late 1980s and early 1990s, Grinnell mathematician, Eugene
Herman, developed a labbased approach for linear algebra

3 50minute lecture/recitation meetings per week
⇒ 3 75minute integrated
lab/lecture meetings per week

At least half of class time devoted to lab

Labs included readings combined with exercises for Maple (later Mathematica)

Collaboration in lab encouraged

Student success rates seemed better than traditional pedagogy

Approach widely discussed at various talks, workshops (e.g., through the
Mathematical Association of America)
Basic question: If a labbased format works well for linear algebra,
why not for other courses (e.g., introductory computer science or calculus)?
Work discussed here reported extensively

Peerreviewed papers

International, national, regional conferences following doubleblind review
