Abstract:
|
We present an overview of a project that aims to transform the introductory statistics course by putting the process of statistical investigations and the logic of statistical inference at its center. One key idea is to present the entire process of statistical investigations (from data collection to data analysis to statistical inference to drawing conclusions) over and over throughout the course. Our hope is that students develop a deeper understanding of key concepts as they encounter them multiple times in new situations. A second key idea is to use simulation of randomization tests and sampling distributions, rather than normal-based procedures, as the starting point for student investigations of the concepts of inference. We provide examples of student activities and also present preliminary findings from our work on assessing student learning with this approach.
