National Science Foundation Funds SIMIODE Three Year Grant

The National Science Foundation Division of Undergraduate Education has awarded SIMIODE a three year grant (15 March 2018 award date) to promote the use of modeling in motivating and teaching differential equations in high schools and undergraduate institutions. We are pleased at this vote of confidence in SIMIODE as reflected in National Science Foundation funding and we will use the funds wisely to spread the word of using modeling in teaching differential equations.

NSF Funds will support a second year of Developer and Practitioner Workshops this July at George Fox University, Newberg OR USA, and will support comparable workshops in July 2020 at Virginia Wesleyan University, Virginia Beach VA USA. SIMIODE leadership will be supported for travel to national and regional meetings to organize contributed paper sessions, lead minicourses and workshops, and develop community through personal interactions. Further, funds will be used to enrich, enhance, expand, and enable new programs of the SIMIODE web community on line and to assess and evaluate the effectiveness of the workshops and the overall SIMIODE program to help faculty to use modeling in teaching differential equations coursework.

Recent publications of Modeling Scenarios in SIMIODE

Author, Jean Marie Linhart, says in her abstract to  her Modeling Scenario Ballistic Modeling-Sponge Dart "The goal of this project is for students to develop, analyze, and compare three different models for the flight of a sponge dart moving under the influences of gravity and air resistance."

Humans vs. Zombies is the subject of the Modeling Scenario authored by Hope McIlwain, Mercer University, Macon GA USA. She got the idea from a Zombie game played on campus by the students. Jue Wang of Union College, Schenectady NY USA, authored another Zombie MOdeling Scenario, ZombieGameHvZ. Dr. Wang authored four exciting Modeling Scenarios. Congratulations to her!

Victoria Rayskin, Tufts University, Medford MA USA, produced a very interesting Modeling Scenario on Internet Platform Users. Dr. Rayskin says in her abstract, "A model estimating the volume of users interacting through a two-sided Internet platform (allowing interaction of two types of users) will teach students how to analyze a 2-dimensional dynamical system. The model will illustrate how the question of existence of closed orbits can be investigated."

Drones Heading Home is the subject of a Modeling Scenario produced by  Richard Spindler, SUNY Plattsburgh, Plattsburgh NY USA, and then modified by two participants from the SIMIODE MINDE Workshop,  Eric Stachura, Kennesaw State University,Kennesaw GA USA and Robert Krueger, Concordia University, Saint Paul, St. Paul MN USA, into a new Modeling Scenario Delivery of Drone Packages.

Mehdi Hakim-Hashemi of Mathematics, Normandale Community College, Bloomington MN USA authored several Modeling Scenarios, one of which was, on the Poisson Process in which, ". . . students learn to derive the probability density function (pdf) of the Poisson distribution and the cumulative distribution (cdf) of the waiting time. They will use them to solve problems in stochastic processes."

These Modeling Scenarios were produced in our NSF Funded Faculty Developer Workshop (DEMARC) at Manhattan College, Riverdale NY USA in July 2018. You can look for them in What's New under Resources in our Main Page Banner. Check them out.

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 using our peer reviewed, double blind referee system.

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 new ideas and activities for students is a main goal of SIMIODE.

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.

Comments Help Create Community at SIMIODE

For each Resource posting in SIMIODE community members have the option to post COMMENTS. This is strongly encouraged as it will build conversations which will connect colleagues, improve material, and build community.  Any posted Comment will be emailed to the author of that resource and conversations can then begin.

Giving feedback, reactions, and corrections to authors is very important for the individual author and the wider SIMIODE community. If you visit and scan/read or actually use a Modeling Scenario or Technique Narratives please offer comments. You may even wish to upload a new resource which has significant added-value. If so then contact Director@simiode.org to inquire how you can do this. We would welcome such efforts.

Call for Technique Narratives for SIMIODE

We publish more and more Modeling Scenarios all the time. Indeed, these are the core of support material for colleagues planning to do more modeling in support of learning differential equations.

It is also important to offer colleagues and their students what we call Technique Narrative activities. These are closer to the traditional material of solution strategies and methods offered in differential equations courses and may help faculty in a more comfortable transition to using modeling in their teaching. SIMIODE offers a small but growing list of Technique Narratives. As with Modeling Scenarios, we have a Student Version in which the STATEMENT of the problem is offered with supporting materials and we have the Teacher Version in which COMMENTS are offered to assist in planning, teaching, and carrying out the modeling activity.

A good example of a Technique Narrative is found in 1-002-S-Text-IntegratingFactor. Here the solution method of Integrating Factor is illustrated and exercises are placed in the context of science and engineering applications so the student can see not only the technique, but the worth of using the technique in context.

All Technique Narratives are FREE, downloadable, and customizable under the most generous Creative Commons license. Visit here to see them all. The list is small, too small, so we request that you share your approaches to solution methods through writing them up for publication, just as you would a Modeling Scenario. They are fully searchable by topics and area of interest to you.

FREE Online Differential Equations Texts

We offer annotated listings of FREE online differential equations texts. This is one of the more popular sections when colleagues visit our site. There are over two dozen such texts. Colleagues have shared their materials in complete text form, often with traditional course structure, as well as rich sets of resources from which to teach. Most texts offered cover the basics of technique and offer exercises. Many offer modeling applications. Your students will appreciate a FREE text and you might enjoy the fresh approaches taken in such presentations. Try it!

This is one of our more popular "landing sites" for visitors to SIMIODE.

Ideally we believe one could save students lots of money by using a FREE online text along with SIMIODE Modeling Scenarios. Make the move for your students and enjoy the excitement of using modeling to motivate learning in your differential equations course.

Sources for Your Own Modeling Scenarios

SIMIODE offers potential modeling scenario ideas. There are hundreds of these!  These are materials, thoughts, pointers, summaries, articles, etc. to encourage and support your modeling scenario ideas. You must be registered and signed in to view these resources. Consider these ideas and use them to design your own modeling scenarios for your students and then publish this material in SIMIODE. 

Of course, you can publish your own source materials, perhaps ideas you have not been able to get to, but want to or wish to engage with others in producing a Modeling Scenario. Just upload them for all to see. Use the "Start a new Potential Scenario Idea" button and contribute.
