These activities include data-gathering experiments, model formulation and fitting, development of solution methods, and comparison of results with the original problem. There are many variations of this format at schools that have used our materials. Each lab team submits a written report almost every week. Three reports per semester are formal submission, instructor review, resubmission for a grade. Classroom teams work on a variety of projects that don't require technology beyond their calculators, but that often would be too difficult for individuals to do alone.
Homework is assigned to individuals, typically collected and graded a week at a time.
