In-class Participation

The fifteen group practices, worth 15 points, and how they double as your attendance record.

Fifteen group practices in Weeks 1–13, 15 and 16, worth 1 point each, 15 points in total. Week 14 is Thanksgiving break, the only week of the term that carries none.

Each Session 1 closes with a short practice problem. Work it on paper with your group on the provided worksheet and write everyone’s names on it. Photograph your group’s own attempt before the instructor walks through the solution. We finish by checking the method, the main results with units, and a common mistake together. One of you uploads the photo to that week’s Canvas assignment by the end of class; the sheet itself stays with your group. One upload covers the whole group, but the point is graded individually: it is credit for taking part in the modeling process, not for getting it right, so it goes to the people who were in the room, and a name on a sheet you weren’t there for earns you nothing. Two weeks differ: Week 1’s runs at the end of Wednesday’s session, because Monday Aug 24 is the course introduction and collects nothing, and Week 16’s is a review exercise in choosing a method for a problem that arrives with no chapter attached.

The uploaded sheet is also half of your attendance record, so one habit matters more than any other: check that your own name is on the sheet before your group uploads it. A sheet carrying only names, with no attempt at the problem, counts as nothing submitted. On a session with no in-class work, your signature alone decides attendance. Exam sessions include your individual test. The 3-3-3 rule has the rest.

Group practices are in-class work, so they cannot be made up, the only exceptions being an approved AES accommodation or a religious observance arranged in advance. The exams are different: each has a real make-up path.
