1. Teaching CHEM 12171 Classroom format: 75 minutes total (~40 for presenting problems; ~30 for group work/discussions) Presenting problems: Setting up & giving background but NOT SOLVING Each week, 4 students pre-assigned to present one problem each Required to meet with a TA during office hours to go over problem Make sure student understands problem Make sure student does not give too much info for problem ~5 min at beginning, each presenter puts up on the board the info they want as visual aids Small groups of 4-5 students, rotate through and hear each presentation and have opportunity to ask questions/discuss with the presenter (max 10 minutes before rotating) In groups of 4-5 students, work to solve problems

2. How students should present Read part or all of the problem Set-up the problem by addressing the following: Q1: What background info do you need to know? Q2: What concepts do you need to understand? Q3: What are the big picture ideas involved in this problem? Notes: Just because I label them Q1, Q2, Q3, you don’t always have to answer these questions in this order when explaining a problem. You won’t always answer all three questions when explaining a problem. There might be other, more-appropriate questions to answer when explaining a problem.
