In response to the question, "What is Inquiry-Oriented Differential Equations?" the IODE team responds, "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." The site leaders go on to refine their terms, "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."

The site offers a set of GeoGebra tools in support of the material in the online text. GeoGebra is a free downloadble software package with exceptional graphics and instructional capabilities.

This effort is a nice combination of reasonable and engaging applications to motive the differential equation concept under study, use of technology (GeoGebra), and careful step-by-step solution strategies for solving differential equations.

If you are considering saving your students a bundle of money by not having them buy a version n (for n large) of any of the available texts then this text is something you might well consider.
