New Listserv

For more immediate conversations about these issues, also consider joining the Simulation-Based Inference Listserv. The SBI mailing list  is intended for individuals interested in discussing pedagogical issues related to using simulation-based inference techniques (e.g., randomization tests) in introductory statistics courses as the primary introduction to statistical inference. For more information or to subscribe, go to https://www.causeweb.org/mailman/listinfo/sbi.

Assessment Opportunities

We are looking for individuals/institutions willing to give common assessment items during Winter/Spring 2015.

  • Pre/Post attitude surveys (SATS)
  • Pre/Post concept inventory (modeled after CAOS and GOALS)
  • Embedded multiple choice exam questions (Unit 1: One Proportion, Unit 2: Two Proportions and/or Two Means)

We will send you names of students who participated (if you want to give course credit) as well as a report at the end of the term with your student results and comparison results. For more information, please contact Cindy Nederhoff <Cindy.Nederhoff@dordt.edu>.

we worry that the motivation for conducting bootstrapping is less intuitive for students

Beth Chance, Cal Poly – San Luis Obispo

My technology use has definitely evolved, including in ways that surprise me!  In particular, I have switched from being a long-time advocate of Minitab to not using a standard statistical package in the course at all.  In reflecting on why this was the case, I realized I had some guiding principles:  

I want student to see simulation-based methods as equally legitimate to theory-based procedures, if not preferred in some situations.
