Applied Abstractions

My thoughts on teaching mathematics, using technology to teach, and finding ways to become better at both, with explorations into the education research literature. All thoughts my own, and not a reflection of any employer.

Planning for the Fall: Flipping my class and shadow grading

July 27, 2021

In a previous post ( Pre-Pre-(Pre?)-Planning: Fall 2021 - Standards based grading, flipped classroom, corequisite support, and maybe group work? ) I discussed my plans for the summer. I just completed the course Flipped Plus Model taught by Jessica Bernards and Wendy Fresh , and my plans for my fall course have changed slightly. This course I am teaching is a corequisite support version of our 100-level business math class, and contains both prerequisite math topics, and success skill assignments. This will be the first time I have taught a face-to-face course since March of last year, and for various reasons 5/8 of the course (100-level math content) will be face-to-face, with the remaining 3/8 (prereq math topics and success skill assignments) online. In that previous post I discussed standards based grading, and while it is something I'm still interested in I think I am going to focus for the month of August on 'flipping' my course. This is half inspired by Flipped...

Chat GPT, Stats, and Math: What are we going to do?

December 29, 2022

Along with everyone else freaking out about Chat GPT ( John Dickerson did a nice segment on CBS ) I thought I might test it out with a few basic questions from classes I teach. This year my focus is on introduction to statistics, so I thought I would start by asking it a few open-ended and computational questions.

Culinary Math and Visual Mnemonics

September 26, 2014

For the upcoming fall term I've been contracted to teach a culinary math class at a local culinary school. The course deals primarily with units of measure, yields, and recipe costing. Doing my own research into the course content I found an excellent resource in Culinary Math , by Linda Blocker and Julia Hill. Overall it is an excellent introduction into the mathematical topics that are important to cooks and chefs, and the terminology they've developed around them. One aspect of the book that I really enjoyed is its use of visual mnemonics . The first one they use is this one to show the relationship between cups, pints, quarts, and gallons: Within each 'P' there are two 'C's, indicating that there are two cups in every pint, and so on; two pints to a quart, four quarts to a gallon, etc. This has a really nice recursive relationship as well, within each 'Q' there are four 'C's, meaning there are four cups in a quart. The design of it is ...
