Overview of the Project
This website is the result of project funded by NSF (Grant No.DUE-9752523 ) to develop and disseminate materials that help students learn core concepts underlying statistical inference. We have created instructional modules that use simulation software to help students develop abstract concepts such as sampling distribution, confidence interval, p-values, and power. Based on our previous research, we have based the modules on a model of conceptual change where students first make predictions and then test them using the simulation software. These modules also include assessment instruments to assess prerequisite conceptual knowledge and instruments to assess understanding of the statistical concepts underlying statistical inference.
