This study investigates the development of teachers’ understanding about statistical investigations as a result of a graduate course on teaching and learning statistics across two institutions. Using the Guidelines of Assessment and Instruction of Statistics Education (GAISE) framework, we examined teachers’ report as they use technological tools to examine two sets of data on the pre and post. Preliminary results show that teachers improved their understanding about four components of a statistical investigation—formulate questions, collect data, analyze data, and interpret results.
