Information
I have used Plickers in both high school and college classes with as many as 72 students and will show its effectiveness as a tool for both teaching statistics and learning students’ names. Participants will begin by roleplaying as a student learning about randomized response trials using Plickers cards. They'll flip a coin and the results will determine whether they’ll answer a question honestly or as instructed and the data will be transferred to excel, where probabilities will be calculated. The participants will then practice scanning Plickers cards of students who have constructed confidence intervals and are reporting whether their interval contained the true population mean. The students will learn about the interpretation of a confidence interval as well as Type I and Type II errors in this activity. Finally, participants will be presented with other detailed examples of how to use Plickers to teach concepts such as bar graphs, randomization, variance and binomial probabilities. They will be welcomed to add their own ideas to a poster to share with others.
