SCUDEM IV 2019 Seeks Host Sites
SCUDEM IV 2019 will take place in local sites around the world on 9 November 2019. We are seeking local site host coordinators for this event. SCUDEM, which stands for SIMIODE Challenge Using Differential Equation Modeling, offers teams of three undergraduate or high school students three modeling problems. Each team selects the problem of their choice and works on it for a week before Challenge Saturday, 9 November 2019. Student teams with their coach travel to a local site (your school perhaps) near their home campus for a day of collegial sharing. Here they submit an Executive Summary for judging; work on an additional feature for their problem but do not redo their model; participate with faculty in an active use of SIMIODE Modeling Scenarios during a first portion of a Faculty Development program along with faculty; enjoy the fun of team MathBowl; make a 10 minute presentation of their model results and get immediate feedback on their work by faculty judges. Faculty dig deeper into pedagogical issues of modeling in a second portion of the workshop,
Currently SCUDEM IV 2019 has 56 local site host coordinators around the world, in Latin America, Europe, Asia, Africa, and United States.
Faculty coaches and other members of visiting faculty participate in a two part Faculty Development workshop in which they experience (with students) SIMIODE Modeling Scenarios and discuss using modeling in their differential equations course. During the closing ceremony awards (Outstanding, Meritorious, and Successful) are presented.
Host sites receive a check of one half the visiting teams' $100 US registration fees in support of their hosting, while SIMIODE provides ALL materials for success on Challenge Saturday. SIMIODE provides massive email lists (over 85,000 mathematics faculty members) for local invites, recruiting letter materials, and an attractive flyer which can be personalized to help bring teams to the local campus site for SCUDEM. We have a complete Local Site Host Coordinator Guide and a special Group in SIMIODE for hosts to keep them informed and permit sharing of helpful ideas and approaches.
Team registration opens on 1 September 2019 and runs through 25 October 2019.
Be sure to check out the convincing videos in which students and faculty share their enthusiasm and experience in engaging in modeling with differential equations in SCUDEM events past.
There are no registration fees for SCUDEM IV 2019 in developing countries. This is our way of reaching out and supporting colleagues from these regions.
We invite all to join the Facebook Group - SCUDEM Mathematical Community.

SIMIODE at MathFest 2019 Cincinnati OH USA 31 July - 2 August 2019
At Mathfest 2019, Cincinnati OH USA, 31 July - 3 August 2019, SIMIODE is sponsoring a Contributed Paper Session entitled, "Showcase of Modeling to Motivate Differential Equations," There will be two sessions, both on Friday, 2 August 2019 with morning session 10:10 AM - 12 Noon in DECC 233 and afternoon session 1:30 PM - 4:10 PM in DECC 233. Fourteen speakers will be featured in response to the following call for papers.
“Modeling can motivate the learning of differential equations, which is a pivotal STEM course taught in high schools, two-year colleges, and four-year institutions. Student backgrounds and intended majors, faculty backgrounds, and departmental constraints provide for many variations in the course. Modeling can be incorporated into any version to introduce and motivate the study of differential equations and show its broad interdisciplinary. Scholarly presentations will share modeling materials and data collection experiences that generate active, inquiry-oriented learning. Presenters may discuss the value of modeling to themselves as teachers and to their students as learners, as well as assessment techniques and pedagogical successes and challenges.”
Come and join the sessions to hear enthusiastic presentations, learn how you can incorporate more modeling in your differential equations course, and enjoy the sharing. See you there!
SCUDEM Gathering and Information Center for those interested to learn more about SCUDEM IV 2019, 9 November 2019, will be a chance to learn about SCUDEM for you, your school, and your students from 4:30 PM to 6:30 PM, Friday 2 August 2019 in DECC 236. Come and share your questions and experiences.

SIMIODE is a Community of Practice - Forums for Conversations
We are pleased to announce that SIMIODE is a Community of Practice in the broad sense as defined by Etienne and Beverly Wenger-Trayner. SIMIODE is more than a set of resources and ideas for using modeling to motivate and teach differential equations. SIMIODE is Community and welcomes conversations, blogs, forums, and exchanges about practices, examples, experiences, materials, stories, student feedback, successes and improvements, and much more. Join us at SIMIODE Community of Practice and engage in meaningful conversations and exchanges. There are several places in SIMIODE in which we offer Forums on member interest topics. Once inside Community of Practice scroll down to Forums (Fora) for SIMIODE Members. Examples include Use of Modeling Scenarios and Student Conversations about Modeling in Differential Equations Course. These and other Forums can be found in the Forum Page as well.
Also there may be forums found in your Groups, for example in the Teachers Group (our biggest group) we just added a Forum to other forums present called, "Modeling with Numerics" about fostering an exchange of ideas and experiences in using modeling to motivate numerical methods and programming for post calculus coursework, particularly differential equations. You can find Group defined Forums in your Dash Board once inside a Group of interest under Forum. Registered members can form a Group, invite members, and create their own Forums OR contact Director@simiode.org about forming a broader Forum for others to visit.
We have several ways to grow a Community of Practice. One way of doing so is introducing yourself to the community by making your profile rich in detail about your interests and background with use of tags and contact information. In SIMIODE one can search for colleagues by name or by interests using information you put on your Profile in the form of tags. We encourage folks to put themselves out there for others to find them and build connections. It could be a grad school buddy, a colleague from a former school, a person with the same advisor, a neighboring school associate, a friend, etc. When you make contact then pick up a conversation about uses of modeling in differential equations, the reason you are in SIMIODE!

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.
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 Director@simiode.org. We will respond quickly!
Recently, Virgil Ganescu, York College of Pennsylvania, York PA USA, published a rich Modeling Scenario 3-067-S-RLCSeriesCircuit in which he introduced the reader to an exceptionally good circuit building software, Multisim, which is FREE for use to build the second order linear ordinary differential governing equation of a small signal RLC series AC circuit. Students then solve the equation analytically and the results are compared with the data acquired from analyzing the numerical model of Multisim.
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.

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. If you are using one of these texts then please prepare a review for publication and send it to Director@simiode.org for others to know about how you use the work and save students money! Or you can add your thoughts to the Comments tab at each text's listing. Other will value what you have to say, so take this request to heart and share your thoughts and experiences.
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.
