As of late, I have been working a lot to improve the Differential Equations experience in Math 244. On the Youtube Channel, there are two different lists of Math 244 videos, a flipped classroom version where the videos cover the entirety of the course content from Summer 2017, and a set of introductory videos that were used before a synchronous online class in Spring 2021.
In addition, there is another playlist of example videos from the various sections of 244, as well as some extra topic videos from random sections where more videos were merited.
The notes (blank and filled) from both the Introductory Videos and the Topic Videos can be found at the website here.
Finally, I have been revising the MATLAB assignments for this course. A help page for students can be found here.
