Students suggest possible structures for a molecule and the vote on which ones are correct. Then, two or three students can be selected to calculate the structure on the chalkboard, while the rest of the students do so with paper and pencil. They walk through the formal calculations and compare their answers to the results of the voting at the beginning of the class.
The purpose of this activity is for students learn more about "Problem Oriented Policing" (P.O.P.) methods, in contrast with traditional and community approaches to policing, and it was meant to especially drive home the challenges and complexities of the Scanning, Analysis, Response, and Assessment (SARA) model of police work.
In this repeating activity, clickers are used in lecture to test for understanding and encourage participation. Professor David Harrington uses "clicker questions" 3 times per lecture to engage students directly with material.
