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. Why this format and the value of it Learning to effectively work in groups Everyone needs to learn how to collaborate Active learning (see Learning Pyramid) Address past issues with tutorial Students not coming prepared to tutorial Students not working well in groups Students working on work for other classes Students not using office hours Students not seeing relevance of tutorial

3. 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.
