Freakanomics Radio's "America's Math Curriculum Doesn't Add Up"

"I believe that we owe it to our children to prepare them for a world they will encounter, a world driven by data. Basic data fluency is a requirement, not just for most good jobs, but for navigating life more generally." -Steven Levitt

Preach it, Steve. This edition of the Freakonomics podcast featured guest host Steven Levitt. He dedicated his episode to providing evidence for an overhaul of America's K-12 math curriculum. He argues that our kids need more information on data fluency.

I'm not one to swoon over a podcast dedicated to math curriculums, but this one is about the history of how we teach math, the realities of the pressures our teachers face, and solutions. It is fascinating.

You need to sit and listen to the whole thing, but here are some highlights:

Our math curriculum was designed to help America fight the Space Race (yes, the one back in the 1960s). For a world without calculators. And not much has changed.



Quick idea for teaching regression/correlation
14:20: Economist Dr. Sally Sadoff had students perform regression by going out into the world and collecting two data points the students were interested in. She describes how one under-performer measured the relationship between hair spray use and hair damage, which was of interest to a make-up obsessed student.

Psychometrics lesson in the creation and revising of the SATs

23:30: HOLY SMOKES. Information on why the SATs were created and how they were totally biased in favor of the affluence. I think this would be an interesting case study in RM, good intentions, and the road to hell.



Another old SAT question includes this gem:



Arguments and information to share with your students as they wonder whether or not they will ever use stats:


Other interesting data about the current job environment:

7:40: 90% of the data ever created by humanity was created in the last two years. 7 of the 10 largest growing job titles are data related.

  36:40: They discuss a survey that asked participants what math they wish they had learned in high school. Participants wished they had more lessons in statistical literacy. Specifically, they wanted they knew how to analyze data to gain insights (65% of participants) and how to make data visualizations and use data to make an argument(60% of participants.).

Ways to use funny meme scales in your stats classes

Have you ever heard of the theory that there are multiple people worldwide thinking about the same novel thing at the same time? It is the multiple discovery hypothesis of invention . Like, multiple great minds around the world were working on calculus at the same time. Well, I think a bunch of super-duper psychology professors were all thinking about scale memes and pedagogy at the same time. Clearly, this is just as impressive as calculus. Who were some of these great minds? 1) Dr.  Molly Metz maintains a curated list of hilarious "How you doing?" scales.  2) Dr. Esther Lindenström posted about using these scales as student check-ins. 3) I was working on a blog post about using such scales to teach the basics of variables.  So, I decided to create a post about three ways to use these scales in your stats classes:  1) Teaching the basics of variables. 2) Nominal vs. ordinal scales.  3) Daily check-in with your students.  1. Teach your students the basics...

Leo DiCaprio Romantic Age Gap Data: UPDATE

Does anyone else teach correlation and regression together at the end of the semester? Here is a treat for you: Updated data on Leonardo DiCaprio, his age, and his romantic partner's age when they started dating. A few years ago, there was a dust-up when a clever Redditor r/TrustLittleBrother realized that DiCaprio had never dated anyone over 25. I blogged about this when it happened. But the old data was from 2022. Inspired by this sleuthing,  I created a wee data set, including up-to-date information on his current relationship with Vittoria Ceretti, so your students can suss out the patterns that exist in this data.

If your students get the joke, they get statistics.

Gleaned from multiple sources (FB, Pinterest, Twitter, none of these belong to me, etc.). Remember, if your students can explain why a stats funny is funny, they are demonstrating statistical knowledge. I like to ask students to explain the humor in such examples for extra credit points (see below for an example from my FA14 final exam). Using xkcd.com for bonus points/assessing if students understand that correlation =/= causation What are the numerical thresholds for probability?  How does this refer to alpha? What type of error is being described, Type I or Type II? What measure of central tendency is being described?
