Differential Equations: A Toolbox For Modeling The World


1 May - 15 June 2022 SIMIODE offers 20% discount in the price $39.00 to $31.20

Get your copy now and consider using this exciting approach with your students at the next teaching opportunity. Students purchase your copy for project ideas, challenging and exciting modeling applications, and motivation to study and apply differential equations. Make this part of your summer reads! Enjoy and marvel at the rich applications of differential equations.

SIMIODE offers its digital online textbook, Differential Equations:  A Toolbox for Modeling the World. The online low cost textbook is available for purchase through SIMIODE. 

Hundreds of colleagues have purchased this remarkable text and many are using it to excite their students to the modeling possibilities of differential equations in the classroom.

Authored by the distinguished teacher and writer, Dr. Kurt Bryan, Rose-Hulman Institute of Technology, Terre Haute IN USA, this text takes a modeling first and throughout approach to motivate the study and learning of differential equations in the spirit of SIMIODE, while linking to many SIMIODE Modeling Scenarios and other original activities.

Dr. Glenn Ledder, University of Nebraska, Lincoln NE USA, says in his review in The UMAP Journal, “This book is the only one this reviewer is aware of that presents differential equations in a modeling context rather than merely adding a bit of modeling to the standard presentation. If you want to study the mathematics of differential equations in a modeling context, you are in the right place.”

Here we offer a copy of the Table of Contents and Chapter 1 to demonstrate our commitment to a modeling first and throughout approach in teaching differential equations. 

The text offers some 600 pages of rich modeling motivated materials with support groups in SIMIODE for Students and Teachers with some 400 additional pages of materials (solutions, hints, project ideas, data, computer code, forums, collaborative project space, etc.) to help teacher and student at SIMIODE Textbook - Teacher Group or a SIMIODE Textbook - Student Group.

Differential Equations:  A Toolbox for Modeling the World puts applications and modeling front and center in an introduction to ordinary differential equations. In taking this approach we do not skimp on or skip over the mathematics, but use applications to motivate both subject and technique. The mathematics presented is interwoven with modeling to drive both the mathematics and understanding of the applications under study and to make the case that differential equations provide a powerful, indispensable toolbox for describing the world.

Again, purchase this textbook, use SIMIODE resources, support SIMIODE, enjoy the read, and adopt the text for your course on behalf of your students.

Prison Mathematics Project

At the SIMIODE EXPO 2022 Conference there was an exceptional Keynote talk followed by an informal Breakout discussion, given by Amit Sahai, Computer Science, University of California, Los Angeles CA USA; Christopher Havens, Executive Director and Founder, Prison Mathematics Project, TRU at Monroe Correctional Complex, Monroe WA USA; Ruth Utnage, Executive Assistant, Prison Mathematics Project, Seattle WA USA; Trubee Davison, Mathematics, Western Colorado University, Gunnison CO USA; and Timothy Pennings, Davenport University, Grand Rapids MI USA, about the Prison Mathematics Project. The Prison Mathematics Project (PMP) works towards a new understanding of the role of mathematics in self-identity and desistance among a demographic of prisoners who are actively exploring a higher education. The aim is to achieve positive changes in self-identity and desistance by providing knowledge, instilling a sense of community and culture, and establishing network connections to promote self-rehabilitation among participants through engagement of mathematics. Such engagement is nurtured through active mentorship by members of the mathematical community. See the current issue of the Prison Math Newsletter 3.

Publish Your Class Efforts in SIMIODE

If you are teaching differential equations of some sort you have probably written and assigned projects. Consider publishing your materials online in SIMIODE using our peer reviewed, double blind referee system. More and more colleagues are accepting our invitation for sharing and publishing their teaching materials in SIMIODE for others to enjoy. Join in with us!

SIMIODE maintains a double-blind, peer-reviewed process for quality online publication of Modeling Scenarios and Technique Narratives. However, we encourage authors to submit their ideas at any stage of development and/or class projects for immediate feedback of a less formal nature. We will render constructive support and encouragement as well as technical feedback. In the past the SIMIODE Director, Brian Winkel, as Founding Editor of the journal PRIMUS, found this to be a very good way to foster confidence, help prospective authors contribute to the broader community, and get their ideas published.  Please drop us a note with your ideas and/or materials to We will respond quickly!

You can see how to submit your materials here. What you do is important to your students, but it is also worthy of sharing with colleagues and their students. Step up and write up your projects for SIMIODE. You will have an online refereed publication at SIMIODE. You will be pleased to know others are using your ideas, building on your success, and enjoying what you share with your students. So, what are you waiting for? Just do it!

One purpose of SIMIODE is to offer colleagues solid, refereed teaching material on which they can base a modeling first course in differential equations. Thus publishing your new ideas and activities for students is a main objective of SIMIODE so others can see your fine work and engage their own students in similar manner. However, it is reasonable to ask yourself, "Why should I prepare, submit, and publish in SIMIODE?" Here we give you many good reasons to publish in SIMIODE. Check them out and see that many fit you. Then join us by sending us your efforts.

Otherwise Material

Lucy S. Oremland, Justin R. Dunmyre, and Nicholas Fortune have published a very relevant paper, "Reinventing the Salty Tank Through Guided Inquiry," in PRIMUS, 32(5)(2022): 621-635. 

In this paper, we discuss mathematical modeling opportunities that can be included in an introductory Differential Equations course. In particular, we focus on the development of and extensions to the single salty tank model. Typically, salty tank models are included in course materials with matter-of-fact explanations. These explanations miss the opportunity for students to develop rate of change equations for themselves. In this paper, we highlight an open-ended single salty tank task that provides the foundation for more complicated salty tank models that we also detail herein. Furthermore, we discuss instructional implementation techniques that instructors can use in their classes to meet their specific learning goals.
