Textbook and Learning Modules
We used "Elementary Differential Equations" by William Trench as the base text for this course. Our goal was to enhance the text with interactive features such as Desmos, GeoGebra and Sage interactives. To accomplish this, we used Trench's LaTeX code to create learning modules with interactive features. In addition to introducing interactivity, we edited the first few sections of the text to reflect what we believe is a more traditional approach to some of the topics. The resulting collection of learning modules can be found at https://ximera.osu.edu/ode.
