Clicker Question 1 Which of the following best describes your experience with classroom response systems (clickers)? A: I use clickers extensively in my courses. B: I use clickers sparingly in my courses. C: I am familiar with clickers but have not yet used them in my courses. D: I’m completely new to clickers and their use in the classroom. 11/2/12

Introduction My experience with clickers Effective use of clickers in the classroom Administrative overheads 11/2/12

Experience First experience in graduate school (Ireland ~ 2008) but no personal experience. Extensive use during my postdoc at the University of Washington Use was motivated by recent physics education research, in addition to personal preference. 11/2/12

Physics Education Research “Interactive-engagement versus traditional methods: A six-thousand student survey of mechanics test data for introductory physics courses,” R.R. Hake, Am. J. Phys. 66, 64-74 (1998). Significant findings included that courses that used interactive-engagement methods had much larger gains that courses using traditional methods 11/2/12

Clicker Question Example Two gliders, A and B, collide on a level, frictionless track, as shown below. The mass of glider A is less than that of glider B (i.e., mA < mB). The final speed of glider A is greater than that of glider B (i.e., vAf > vBf). Is the magnitude of the final momentum of glider A, |pAf|, greater than, less than, or equal to that of glider B, |pBf|? A: Greater than B: Less than C: Equal to D: Not sure 11/2/12

Effective Use Clicker questions should ideally foster discussion, and challenge student ideas. Effective questions often address conceptual difficulties. Other questions can be useful in judging the effectiveness of the lecture, by gauging the level at which students understand the material. 11/2/12

Administrative Considerations Should I award course credit for clicker responses? If yes, how much? Should I award credit for correct responses? Shared responsibility between instructor and student. 11/2/12

Audience Response System Turning Point, Turning Technologies

History of VTC at UNC Elizabeth City State University (circa 2005) Historically underserved part of the state Asheville (circa 2011) Class size upon admission 10 to 15 students (ECSU) 142 students (CH) 25-30 students (Asheville)

Primary Uses Knowledge checks (Beginning, Middle, End) More Common Knowledge checks (Beginning, Middle, End) Conversation starters Attention Maintainers Team-Based Learning Student presentations Grade Quizzes Less Common

Conditional Branching How do you want to treat the patient? Stop Meds Do Nothing Hemodialysis Meds are stopped, now what? Pt is hypotensive, now what? Get BP up Hemodialysis Patient Dies Do Nothing Pt BP is normal but refuses dialysis, now what? Patient Dies
