Hi! Remember me??? I traded in some of my overload units to take the spring semester off, and it ended up being a very busy time. I was wrapping up the videos and supplements for my newest textbook (a STEM focused intermediate algebra text) and the second edition of Interactive Statistics (which I work with Michael Sullivan on). Last week I started teaching a summer Intro Stats class, and I have begun to turn my attention to preparing for next…
Last fall I started teaching my intro stats class using the flipped classroom model. I have found many benefits to this approach: My students are more active and engaged in class. I am able to cover much more material than I ever covered before – including simulations, bootstrapping, and non parametric tests. My students level of understanding when it comes to inferential statistics and the “big picture” is higher than ever. I am currently blogging each day, documenting my progress…
The Bootstrap Method The bootstrap method is a very useful tool to have an introductory statistics class. The bootstrap method begins with a sample of size n. Then a large number (I use 10,000 in my classes) of samples of size n are drawn with replacement from that sample. A sample statistic is computed for each sample. A typical use of bootstrapping involves the mean, but this procedure can be applied to the median, quartiles, variance, … Percentiles can be…
I’m really proud of this latest study involving our Interactive Statistics (I am a co-author with Michael Sullivan) by Sam Bazzi at Henry Ford College. I saw Sam present his results at ICTCM and was really impressed. I encourage you to check out his case study. Read the Study Here This reinforces the fact that there is not a better product to use in an online statistics course: students persisted at higher rates and their test scores improved as the…
Had a great time at ICTCM 2017 in Chicago. And I learned a lot. Between Maria Andersen’s opening day keynote and Eric Mazur’s Saturday sessions I feel that I am making good progress in some areas, but there is still room for improvement. My “lecture time” is very active and engaging, but I feel like I need to turn it up a bit and allow my students more time to experiment and discover. I need to use assessment FOR learning. …
On day 7 of instruction in my intro statistics course we spent the class working through a project comparing two population proportions using resampling. Click here to download a pdf copy of the project: Two Proportion Resampling Hands-On First Mike Sullivan recommends a hands-on simulation before turning to the computers, so I began by using poker chips for this scenario: A random sample of 15 students at my college had 9 female students in it (60% female), while a random…
Looking forward to my session on the importance of student discovery in developmental math at ICTCM this weekend in Atlanta. I will be sharing innovative approaches for getting your students involved in the discovery of material. When students are engaged and thinking the chances for understanding and success dramatically increase. The session is on Saturday morning from 9-9:30. I will be walking through Interactive Statistics in the exhibitor’s room from 10-10:30 on Friday morning. This is the new product I…
