With Andrew Ross (Eastern Michigan University)
Secondary students are expected to learn how to informally evaluate evidence of a difference between two groups. At the 7th grade level, they look at the "difference between the centers by expressing it as a multiple of a measure of variability" and "Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations". At the high school level, they "Use data from a randomized experiment to compare two treatments; use simulations to decide if differences between parameters are significant" (Common Core State Standards for Mathematics). In this presentation, we will share new teacher education curriculum materials from the MODULE(S^2) project which prepare teachers to teach students how to evaluate evidence of a difference between two groups. The materials include both content and pedagogical aspects of teaching the topic. Non-presenting co-authors: Stephanie Casey, Samantha Maddox, Melody Wilson.
