What is Inquiry-Oriented Differential Equations?

Inquiry-Oriented Differential Equations (IODE) is a first course in differential equations focused on understanding of the big ideas in first order, second order, nonlinear, and systems of differential equations. The course is designed as a full semester course and topics covered include solving ODEs; numerical, analytic and graphical solution methods; solutions and spaces of solutions; linear systems; linearization; qualitative analysis of both ODEs and linear systems of ODEs; structures of solution spaces.

What is Inquiry?

Our use of the term inquiry includes the following three principles: deep engagement in mathematics, peer-to-peer interaction, instructor interest in and use of student thinking. For further reading on these principles of inquiry and inquiry-oriented instruction see the articles by Rasmussen et al. and Kuster et al.
