This document summarizes a presentation about using classroom response systems, also known as clickers, to improve student conceptual understanding in mathematics courses. The presentation discusses the benefits of clickers for inclusivity, gathering formative assessment data, and increasing student engagement. It provides examples of how clickers can be used for polling, focusing questioning, and motivating group work. A significant portion of the presentation focuses on implementing peer instruction, a pedagogical technique where students teach each other concepts through multiple choice questions designed to address common misconceptions. Attendees worked in groups to design sample peer instruction sessions for calculus topics. The presentation emphasizes that focusing on conceptual learning improves problem-solving skills even if less class time is spent

Sort algorithms.

(b) 2
(c) 3
(d) 4
(e) 5 (= Very familiar with these)
What could you do with this information?

these courses, what is the maximum amount of money you’d be willing to pay
for this fee?
(a) $0 (= I don’t want a fee)
(b) $5
(c) $10
(d) $25
