EOSC114 spring 2008 - summary of PRS responses
Introduction
This page contains all questions generated in Spring term 2008 for use as in-class clicker questions. There is a separate table for each of six modules, and each row
gives the module's day, question number, question and the bar graph summarizing student responses. A 20-pg PDF version is available for printing.
For questions with no response data the Responses
column contains a "no data" figure. Question may not have been used owing to lack of time, or some other reason. Questions are in the form of text for Roland's set
because the PRS software does not reproduce the image properly from the Apple system (this is one of several reasons why a normal PRS "report" was not generated
for this summary). Questions for other sections are given as an image of the corresponding PowerPoint slide. Some questions appear twice. Some instructors used
such questions in a pre-lecture, post-lecture manner. Other times the instructor may have intended to use it in one lecture but ran out of time.
