SCUDEM IV 2019 Seeks Host Sites Before Opening of Registration on 1 September 2019

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 61 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.

In our 12 July 2019 Blog we highlight the results from a recently published article, "Building mathematics self-efficacy of STEM undergraduates through mathematical modelling," in the International Journal of Mathematical Education in Science and Technology, in which the authors conclude that SCUDEM increases students' self-efficacy in mathematical modeling. Do SCUDEM for your students!

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!

CALL FOR PAPERS SIMIODE Sessions at Joint Mathematics Meetings 2020

SIMIODE has been granted two paper sessions AND a Minicourse at the AMS/MAA Joint Mathematics Meetings in Denver CO USA, 15-18 January 2020.

We have been granted a fourth (in a row) AMS Special Session entitled, "Wall to Wall Modeling Activities in Differential Equations Courses." This session is organized by Janet Fierson, La Salle University, Therese Shelton, Southwestern University, and Brian Winkel, SIMIODE. The essence of the session proposal is here, "Presenters will share and demonstrate the modeling activities used in their own differential equations or modeling courses, thus engaging the audience as participants. Attendees will have the opportunity to experience these activities from the perspective of students learning the relevance of differential equations to realistic situations. Both pedagogical and technical details will be presented, and audience reflection will take place." Abstracts are accepted until Tuesday, September 17, 2019 12:00 AM Eastern Standard Time at the JMM AMS Abstract site

We have also been granted an MAA Contributed Paper Session entitled, "Modeling-First Inquiry-Based Course Activities." This session is organized by Ben Galuzzo, Clarkson University, Corban Harwood, George Fox University, and Brian Winkel, SIMIODE. The essence of the session proposal is in this paragraph, "We invite scholarly presentations of in-class activities, projects, and/or data collection experiences that generate active, inquiry-oriented learning across the mathematics curriculum. The diversity of presented modeling implementations benefits the community through shared resources, support, and new perspectives. Presenters are encouraged to 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."  More details will be forthcoming in the MAA JMM 2020 web site on submission of abstract procedures.

Minicourse #10: Wall to Wall Modeling Scenarios for Differential Equations - yup same title as AMS Special Session!

Part A: Thursday, 16 January 2020, 9-11 AM, Room 704 with Part B: Saturday, 18 January 2020, 9-11 AM, Room 704

This minicourse offers participants active experience in using eight Modeling Scenarios from the double-blind, peer reviewed materials in the resource collection found at the SIMIODE Community of Practice. Time will be devoted to reflection on use in participants’ home setting. We offer this minicourse in support of colleagues who wish to experience modeling activities which can then be used in teaching their differential equations courses. The leadership team of accomplished authors and teachers will demonstrate, using 8 Modeling Scenarios from the SIMIODE repository, how one can effectively use a modeling approach in a differential equations course through the classroom simulation the minicourse will offer. In the process of doing the specific modeling activities during the minicourse we will share with participants information and insight into the many resources of the SIMIODE community. Through minicourse participation colleagues will gain confidence in their ability to bring modeling into their own classroom to teach differential equations and expand their network of like-minded colleagues. Registration will be open in the fall.

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.

Comments Help Create Community at SIMIODE

For each Resource posting in SIMIODE community members have the opportunity to post COMMENTS. This is strongly encouraged as it will build conversations which will connect colleagues, improve material, and foster 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.

New Modeling Scenarios Published in SIMIODE

We are working our way through the fine Modeling Scenarios authored by 20 attendees at our DEMARC - Differential Equations Model And Resource Creators Workshop held this summer at George Fox University, Newberg OR USA. We share some of the work here. We will be offering both DEMARC and MINDE workshops in summer of 2020 at Virginia Wesleyan University, Virginia Beach VA USA (specific dates to be announced).

We cite two Modeling Scenarios of Kurt Bryan, Rose-Hulman Institute of Technology, Terre Haute IN USA (with a third on the way through the review process!) It's a Blast (Furnace) and Matter of Some Gravity  both offer some practical inverse problem approaches involving inverse problems and parameter estimation.

Eli Goldwyn, University of Portland, Portland OR USA writes about the concern for his Water Bottle Cooling while Humi Mayer, Worcester Polytechnic Institute, Worcester MA USA ponders deeper questions and models in A Simple Model for Climate Bifurcation

Eric Stachura, Kennesaw State University, Kennesaw GA USA brings the opportunity to study the development of an invasive species partial differential equation model and Lawrence Udeigwe, Manhattan College, Riverdale NY USA uses phase portraits to analyze relationship dynamics of Romeo and Juliet.

Titles of other Modeling Scenarios to come on line soon include, "Traveling wave analysis of a porous medium model,"  "Earth's Climate a Balancing Act,"  "Using Euler  to Simulate a Thrown Ball," "Falling Meteorite," "Analyzing the Spring-Mass Model Against Empirical Data in the Lab," "Cholera Outbreak," "Yellowstone Lake Predator Prey Model," and "m&m Attrition Warfare." Look for these and more, use them with your students, and add Comments for each resource you use.

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.
