Re: [SBI] Explaining motivation for theory-based models (Ann Cannon)

by Olson Hunt, Megan

Thank you both very much for your responses, Ann and Beth. It's reassuring. I think the transition argument is a good one. "This is where we're going, but this is where we've been and that approach will still be around for quite some time." I too am the only statistics faculty (and in my first year, at that) and it feels like a lot of pressure to make the "right" decision about course content, so it's helpful to hear others' takes on issues. Thanks again, Megan Megan J.

Re: [SBI] New blog posts

A quick follow-up on Beth's comment re: assessment. 1. We are offering a $100 stipend for participating. 2. We'd love to have others at your institution participate also (especially non-users) so feel free to share the link. 3. The pre-post tests are multiple choice, offered online and are a mix of concepts and attitudes questions. We'll provide you a custom report on your students performance when the semester ends. 4. There is an option to include some additional questions on your exams as well if you'd like. 5. You are welcome to participate again this semester, even if you did in the fall.

Simulation methods in an AP course

by Robert Peterson

Does anyone have some insight on how to blend simulation methods concepts with the AP curriculum. Also I will be starting inference soon, so I would love to hear ideas and experiences. My problem is I really love the ISI material, but at the same time my students must know the formulas and conditions from the theory based methods.

Hi everyone and happy new year! Just wanted to let you know about two new topics with postings on the SBI blog (https://www.causeweb.org/sbi/) awaiting your comments. - Should we teach bootstrapping - Incorporating student projects We are also still looking for individuals willing to give some of our common assessment items (multiple choice pre/post, a few open ended), ESPECIALLY if you are NOT doing much with simulation-based inference J Full details, including a link to sign up, are located here at <http://homepages.dordt.edu/ntintle/assessment_intro.pdf> http://homepages.dordt.edu/ntintle/assessment_intro.pdf. Thanks, Beth
