            SCUDEM for You and Your Students - REGISTER NOW     

SIMIODE sponsors a modeling challenge specific to the pivotal STEM course, differential equations. We call it SIMIODE Challenge Using Differential Equations Modeling (SCUDEM). After our very successful inaugural SCUDEM on 14 October 2017 at Mount Saint Mary College, Newburgh NY USA, we offered SCUDEM II 2018 at 40 sites to over 400 students on 21 April 2018.   We report complete results of SCUDEM II 2018.

We offer a SCUDEM I 2017 video  and a SCUDEM II 2018 video in which students and faculty share their enthusiasm for using modeling in solving solve real problems to learn differential equations. Student interviews are very, we mean VERY, convincing as to the value of this modeling competition in their learning and growth in applying the mathematics they are learning.

At the SCUDEM I 2017 site  and SCUDEM II 2018 site we offer complete results including the statement of the posed problems, the additional issues offered on Challenge Saturday, results with all student submissions, award information, way cool  SCUDEM I 2017 video  and SCUDEM II 2018 video, a PowerPoint overview of the event, SCUDEM I 2017 MathBowl  and SCUDEM II 2018 MathBowl fun competitions. Try it. You will enjoy it! You can find answers in the Teachers Group Resources at SIMIODE.

There is also an engaging Faculty Development program offered to support faculty in teaching differential equations courses using modeling to motivate students.

We have announced SCUDEM III 2018, 27 October 2018, with registration from 1 August through  6 October 2018. Register here. REGISTER NOW.

We invite schools to be local hosts for SCUDEM III 2018.  Hosting schools will receive a stipend (one half registration fees) in support of their contribution.  This challenge is for three member teams of students. SCUDEM takes place over a week-long period which will begin with teams selecting one of three modeling problems from physical sciences and engineering, life sciences and chemistry, and social sciences, on Friday, 19 October 2018, at each team’s individual home campus, and culminates with team presentations and a fun day of activities on Challenge Saturday, 27 October 2018, at 9:00 AM at a nearby regional host site in the United States and beyond.

Recent publications of Modeling Scenarios in SIMIODE

How do students relate graphs of functions and derivatives in an SIR model is the challenging them in Meredith Greer of Bates College, Lewiston ME USA shows us how in her Modeling Scenario Functions and Derivatives in SIR Models.

Mary Vanderschoot of Wheaton College, Wheaton IL USA, wrote a fascinating Modeling Scenario on data and modeling Evictions in the United States.

Jue Wang of Grand Valley State University, Allendale MI USA offered several new Modeling Scenarios and we offer up her work on Cancer Growth. Her abstract reads, "This scenario guides students in the use of differential equation models to predict cancer growth and optimize treatment outcomes. Several classical models for cancer growth are studied, including exponential, power law, Bertalanffy, logistic, and Gompertz. They examine the behaviors of the equations and solutions through qualitative techniques. Furthermore, students evaluate how cancer treatments affect tumor growth. Real cancer data are provided to give options for data fitting and prediction of cancer growth. Through step-by-step investigation, conjecturing, predicting, and analyzing, students discover how their knowledge can be used to address complex and real problems, and improve problem solving ability and mathematical reasoning skills."

These three Modeling Scenarios were produced in our NSF Funded Faculty Developer Workshop at Manhattan College, Riverdale NY USA in July 2018 and many more will be published. You can look for them in What's New under Resources in our Main Page Banner. Check them out.

What are you waiting for? Publish 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.

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.

Look for Call for Papers on Modeling Competitions at JMM 2019

SIMIODE is sponsoring a morning and afternoon AMS Special Session  "Using Modeling to Motivate the Study of Differential Equations" and the Call for Abstracts for contributions extends through 25 September 2018. If you are reading this, most likely you have engaged in using some modeling activity in your differential equations course and would professionally benefit from sharing with others. Just do it!

COMAP sponsored Mathematical Contest in Modeling (MCM), Interdisciplinary Contest in Modeling (ICM), and High School Mathematical Contest in Modeling (HiMCM), and SIMIODE sponsored Student Competition Using Differential Equations Modeling (SCUDEM) are team competitions in which students apply the mathematics they know to solve a real world problem. Students routinely report learning more in this 4-day period than any other period during college, and find it one of the most rewarding experiences of their undergraduate careers. Students point to this experience in interviews as an example of working in a team environment, meeting a deadline, and as evidence of their problem-solving ability. The value of participating is worth much more than the four days of work, making this an impactful experience for faculty advisors as well.

This MAA Contributed Paper Session is aimed at faculty who wish to begin advising teams and for current advisors to share strategies for student success. We invite presentations focused on building and supporting student teams, developing mentor relationships for faculty, and presentations elaborating the judging process in order to help advisors better prepare student teams. We especially encourage student teams who have achieved a “Meritorious” or higher rating to report on their contest experience.

You can submit your abstract here and note that the deadline for submission is 25 September 2018.

The publication of this Call for Papers will appear in  MAA's FOCUS and Notices of the AMS.

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!

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.
