Many of us in the United States and around the world are aghast at the tone of this year’s United States presidential election. We are struggling to understand how and why our politics have reached the point that all that we hold dear about our country is in jeopardy. As STEM educators we have an enormous opportunity and responsibility. Our courses can help the debate in several ways:

  • Many of the most controversial topics–for example, climate change–involve the STEM disciplines. We can help inform the debate. Perhaps it is not too late to bring reason to public discourse.
  • Framing public policy questions in scientific terms can often lower the temperature of the debate. Perhaps spreadsheets can replace name-calling.
  • Perhaps most importantly, as scientists we can also study elections and public policy debate themselves. How did we get in this mess? How can we get out of it?

This year’s election season has sparked considerable hand-wringing and even soul-searching by professional journalists. Many worry that the quest for objectivity has enforced a false equivalency in their reporting. As educators we face some of the same problems as we seek to respect the opinions of all our students. In addition, our problems are compounded by the fact that we give our students grades.

We will focus on scientific modeling of how voters evaluate different positions on issues, how they decide for whom to vote, how candidates appeal to voters, and on what we can learn from surveys and polling about ourselves and our politics. We recommend taking the Pew Research Center’s brief Political Typology Quiz before the webinar.

This webinar will be largely discussion based. The organizers will briefly introduce some of the ideas below, but will spend most of the time talking about how these ideas can transform our classrooms and help shape a better and more civil future.

We will also touch on some of the ways in which technology has impacted the workings of the body politic and, especially, the impact of big data. We recommend the book Weapons of Math Destruction by Cathy O’Neil. The short YouTube video below is a brief introduction, especially the last few minutes.

https://www.youtube.com/watch?v=gdCJYsKlX_Y

In addition we will discuss the role that language–ranging from the post below commenting on the book to the words of candidates–has had dividing our nation and poisoning our politics.

Math and Calories

As STEM educators we have contributed to the present situation. For example, the following problem is arguably the most pernicious of the many thousands of textbook calculus problems. (This particular version came from the web site calculus-help.com but versions appear in virtually every calculus textbook.)

Calculus Dirt Farm Problem

The Next Generation Science Standards do somewhat better if they are understood and implemented well. Consider, for example, the highlighted words from the NGSS:

Grades 9-12

Engineering design at the high school level engages students in complex problems that include issues of social and global significance. Such problems need to be broken down into simpler problems to be tackled one at a time. Students are also expected to quantify criteria and constraints so that it will be possible to use quantitative methods to compare the potential of different solutions. While creativity in solving problems is valued, emphasis is on identifying the best solution to a problem, which often involves researching how others have solved it before. Students are expected to use mathematics and/or computer simulations to test solutions under different conditions, prioritize criteria, consider trade-offs, and assess social and environmental impacts.

NGSS

Textbook problems have virtually no relationship to real problems–the problems voters and politicians must address. Textbook problems have textbook answers, whether the one best solution the textbook farmer seeks or the NGSS’s graphic showing a collection of solutions to individual problems, impossibly isolated from their context. There is no one best solution for most real problems. We will discuss how we can teach the topics we already teach with simple examples while emphasizing the complexity of real world settings–especially competing stakeholders and criteria and systems that are simply the sums of their parts.

SENCER Inspires New NSF Grant that Infuses Numeracy Across the Curriculum

Dr. Frank Wang, a SENCER community member affiliated with the SENCER Center for Innovation – MidAtlantic region and professor of mathematics at LaGuardia Community College, was recently interviewed on the CASTpod podcast hosted by Harold Washington College in Chicago. On the podcast, Dr. Wang discussed the NICHE, or Numeracy Infusion Course for Higher Education, project funded by the National Science Foundation.

Prior to NICHE’s inception, LaGuardia launched an intervention for its students who needed help with basic skills mathematics. Because students often struggled with “abstract” approaches to math instruction, LaGuardia used SENCER strategies to teach mathematics through public health issues and the environment, which helped put the disciplinary content into a specific real-world context. Dr. Wang’s NICHE work is inspired by this previous SENCER intervention, and embeds quantitative reasoning in courses across the curriculum.

The interviewer, Kristen Bivens, asked Professor Wang what has been an exemplary application of quantitative reasoning in the project so far. He cited the work of Ester Isabelle Wilder, the NICHE PI, who shows her sociology students that, by the numbers, there are more homeless white people than black people in the United States. However, since the white population is larger than the black population in the United States overall, it is more meaningful in this situation to look at the rates of homelessness between the two, rather than the numbers alone. This is an important lesson in how statistical thinking and quantitative literacy can help us clarify and address civic problems, one that is also addressed in Dr. Cindy Kaus’s Engaging Mathematics teaching manual Introductory Statistics with Student Designed Community-Based Projects, which can be a helpful resource for educators interested in incorporating racial profiling data into their classes.

To learn more about Dr. Wang’s NICHE project and how it relates to SENCER and other areas, and to hear Dr. Wang’s advice on creating positive student attitudes toward math, listen to the interview.

May Webinar "Evidence Matters: Using the Scholarship of Teaching and Learning to Tell the Story of Curriculum Development"

Engaging Math Partner to Co-Host Webinar on Using SoTL to Tell the Story of Curriculum Development

“Evidence Matters: Using the Scholarship of Teaching and Learning to Tell the Story of Curriculum Development”

The Scholarship of Teaching and Learning (SoTL) is a form of research that involves a systematic investigation of teaching practices and student learning followed by peer review and public sharing of the work for others to build upon. This webinar begins with an overview of the key aspects of SoTL, situating it within a spectrum of scholarly work on teaching and learning. Two in-depth case studies, one involving service learning and the other involving sustainability, illustrate how SoTL can contribute to the process of developing, assessing, and disseminating curriculum. One particular SoTL component highlighted in this webinar is the role literature searches play in both shaping and refining questions as well as providing the background context required for publication. Resources for undertaking a SoTL investigation are made available to all participants.

The webinar will be held Thursday, May 5 from 12-1 pm (Eastern).

It will be hosted by:

  • Dr. Jackie Dewar (Professor Emerita of Mathematics, Loyola Marymount University)
  • Dr. Matthew Siniawski (Associate Professor of Mechanical Engineering, Loyola Marymount University)
  • Dr. Rikki Wagstrom (Associate Professor of Mathematics, Metropolitan State University)
Participants new to SoTL may want to view “Inquiring Into Our Students’ Learning – The Scholarship of Teaching & Learning” by Dr. Matthew A. Fisher of Saint Vincent University before the May 5th webinar. This recording provides helpful background on SoTL, and will be referenced by Jackie, Matt, and Rikki during their webinar.

Global Warming: A Zonal Energy Balance Model. Photo credit: Gerard Van der Leun (CC BY-NC-ND 2.0)

Global Warming and Groundwater Modules by Victor Padron

Engaging Mathematics partner Victor Padron of Normandale Community College recently participated in the workshop Teaching Geoscience with MATLAB, hosted by Carleton College in Northfield, MN.

Victor reports that his experience in the workshop was very interesting and motivating. He developed two teaching modules for this workshop that are available to the public through a web repository of educational resources sponsored by the Science Education Resource Center (SERC) at Carleton College.

Here are the names of his modules with the corresponding links and summaries:

Global Warming, A Zonal Energy Balance Model

Summary:

This is a teaching module, directed to undergraduate students in applied mathematics, introducing a Zonal Energy Balance Model to describe the evolution of the latitudinal distribution of Earth’s surface temperature subject to incremental levels of cumulative carbon emissions in the atmosphere. A strategy to avert “dangerous levels” of global warming is imbedded in the model. Students working with the module will write a MATLAB script to solve the model numerically and apply it with their own choice of the relevant parameters to obtain the solution that guarantee controlled levels of global warming.

Summary:

This is a teaching module presenting an introduction to modeling ground water pollution, directed to undergraduate students in applied mathematics. It begins with a brief discussion of Darcy’s law concerning the flow of a fluid through a porous medium. A mathematical model that uses field data to track ground-water contamination is presented. Students working with the module will write a MATLAB script to obtain a numerical solution of the model and apply it to investigate a real event of groundwater pollution.

Engaging Mathematics Co-PI Hosts Webinar on A Future Shared with Robots

Should insurance companies be allowed to use your purchasing history to set prices on your policies? Should self-driving cars be allowed on public roads? What are the implications of robotic police?

These are some of the questions Frank Wattenberg explores during his webinar, Robotics and Artificial Intelligence – Shaping a Future Shared with Robots. Frank is a professor in the Department of Mathematical Sciences at the United States Military Academy (USMA) and a Co-Principal Investigator of NCSCE’s Engaging Mathematics initiative.

USMA uses robotics and artificial intelligence as interdisciplinary topics that cut across the curriculum, helping to unify the academic experience. The topics provide a great context for discussing a wide range of interrelated areas. For example, an assignment on self-driving cars raises questions in economics (Who is liable for accidents?), ethics (What would happen to cab drivers?), and logistics (Should cars driven by humans and self-driving cars be allowed on the same roads?).

Students need to have what Frank calls “intellectual integrity” to successfully program a robotic vehicle to pull into a garage and park itself, without crashing into the garage wall. The kits he uses with his cadets cost about $300 and give students experience with hands-on building and coding. It isn’t enough to get a problem 80% right. If the final product is going to be used in the real world, it needs to work; requiring rigor, tenacity, and attention to detail to perfect the design.

As part of his webinar, Frank led Yuxi Chen, who helped with filming and webinar production, as she built her own self-driving and self-parking robotic car. She used her hand to imitate the garage wall. An ultrasonic range finder mounted at the front of her car sensed the presence of her hand with sound waves, telling the car to stop before a collision.

Designing self-driving cars is a good starting point for cadets because its use in the real world is clear, and because it covers core content, such as linear functions. Another assignment Frank does with his students relates to sentries, or soldiers who stand guard, controlling access to a place. He describes the sentry job as both boring and dangerous–a bad combination for a human, but a perfect task for a robot.

The two big worries with robotic sentries are false positives (taking unnecessary defensive action) and false negatives (failing to take defensive action when there is a real threat). In his webinar, Frank discusses this in the context of a parking garage whose access is managed by a robotic arm. His students graph different scenarios, showing possible behavior patterns of approaching cars that are authorized or unauthorized to access the garage. Students also discuss the varying cost levels of defensive action. Blowing up an unauthorized car before it drives through the gate would be an extreme measure with high cost, whereas raising tire shredders or sounding alarms and flashing lights would be lower cost. This concept of cost, Frank mentions, is analogous to other situations, such as medicine. Different health interventions come at different costs than others.

For more on how Frank uses robotics and artificial intelligence with his USMA cadets, view his webinar.

Frank and his colleague Matthew Mogensen, an instructor of mathematics at USMA, also explored these topics with participants at the 2015 SENCER Summer Institute through a hands-on robotics workshop and panel discussion on the civic implications of robotics and artificial intelligence. Frank (frank.wattenberg@usma.edu) and Matt (matthew.mogensen@usma.edu) invite you to email them with questions about using robotics and artificial intelligence in the classroom, or to continue the discussion further.

Engaging Mathematics Partner to Participate in Teaching Geoscience with MATLAB Workshop

Engaging Mathematics partner Victor Padron of Normandale Community College will be participating in the workshop Teaching Geoscience with MATLAB, hosted by Carleton College in Northfield, MN from October 18-20, 2015.

The workshop is designed to explore how teaching with MATLAB (a high-level technical computing language used by engineers, scientists, and mathematicians) can enhance the student learning environment in undergraduate Earth Science and related courses. MATLAB can be applied to solving problems and developing systems involving mathematical computation, data analytics and statistics, signal and image processing, geographical mapping, and more in the scientific and engineering domains. Workshop participants will help build a collection of teaching activities that showcase the utilization of MATLAB in the classroom.

Victor will be a panelist in a discussion on using MATLAB and data with students. He will present two modules based on versions of his Engaging Mathematics curricula on groundwater and global warming. Both require a computational environment such as MATLAB. The activities produced by the workshop participants will be posted on the workshop website and featured in a new web-based collection devoted to teaching geoscience with MATLAB. Links to these materials will be shared when they are made available. To learn more, visit the workshop website.

VictorDonnay of Bryn Mawr College makes mathematics engaging during 2015 SENCER Summer Institute

Victor Donnay Makes Mathematics Engaging, Interdisciplinary, and Relevant to the Real World

Victor Donnay’s plenary address during the 2015 SENCER Summer Institute had a clear goal—to show the connection between mathematics and the issues people care about.

Victor, who is the William R. Kenan, Jr. Chair of Mathematics at Bryn Mawr College and an advisory board member for NCSCE’s Engaging Mathematics initiative, has the same goal for his students.

Victor uses various assignments to make the connection between mathematics and real world issues clear. During his plenary, Victor shared three examples of such assignments with the audience.

In the first assignment Victor shared, students are instructed to take a homework problem and describe in one paragraph how the mathematics involved might be used to address a real world issue. Students post their paragraphs online and read three others posted by their classmates. From this assignment, something like the concept of related rates in calculus transforms from a general question about how quickly two planes move away from each other into a question about how vocabulary growth rates differ for children born into different socioeconomic classes.

In Victor’s second assignment, students find an article about mathematics in a newspaper or on the web and post it to the class website with a one-paragraph summary. They then read three other summaries and write comments on them. This assignment exposes students to real-world, relevant, and newsworthy mathematics.

In the third assignment, which serves as a final project in Victor’s multivariable calculus course, students pick a world topic that interests them and a topic they learned from the course and show how they are connected. Students present their work at a reception where they can discuss their projects with a general audience.

Victor is also highly focused on issues of environmental studies and sustainability. He chairs the college’s Sustainability Leadership Group, directs the Environmental Studies program, and has taught numerous courses that integrate sustainability with mathematics.

In his mathematics of sustainability courses, he focuses on social, economic, and environmental issues, because all three have an impact on sustainability. His students have studied the Rwandan genocide, population growth models, and tipping points.

Victor worked with TED-Ed to create a short animated video on how tipping points relate to the mathematics of climate change. In the video, titled “Our Chaotic Climate,” chaotic billiard motion explains how a two-degree increase in Earth’s average temperature can lead to substantial consequences.

Victor also incorporates service learning into his mathematical modeling and sustainability course, allowing students to work to make a real difference on their campus and in their community. Student projects range from examining the energy footprint for a renovation of the science building to measuring the level of safety of bike routes. Two of Victor’s students were publicly recognized for their efforts in helping Haverford Township apply for a grant from the Pennsylvania Energy Department Authority to help fund a geothermal energy system for the Community Recreation Environmental Center, a direct result of their service-learning project that explored the center’s options for alternative energy sources.

Students react well to being able to make a difference through their course work. As one of Victor’s students said, “The end results of all the projects were pretty satisfying; it made you feel like you were making a contribution and that you might actually be able to affect something.”

Reactions from the plenary audience were largely positive as well. Overheard were comments from attendees along the lines of, “I never knew this was math!” Victor’s plenary did a great job of showing how mathematics relates to current world problems and topics in many other disciplines, from environmental sustainability to social justice. He helped SSI 2015 attendees see that mathematics is accessible, exciting, and important.

Engaging Mathematics Presents Invited Poster at Largest Math Meeting in the World

In early January Engaging Mathematics partners flew to San Antonio to discuss their work at the 2015 Joint Mathematics Meetings (JMM). The Engaging Mathematics initiative was invited to the JMM to contribute a poster for projects supported by the National Science Foundation’s Division of Undergraduate Education.

Initiative partners also presented individual work. Dr. Rikki Wagstrom (associate professor of mathematics at Metropolitan State University, SENCER Leadership Fellow) and her math education student Jodin Morey gave talks on curricula they developed for Engaging Math. Rikki’s curriculum focuses on the Midwest’s declining milkweed populations and the potential impacts for monarch butterflies. Jodin’s compares greenhouse gas emissions from automobile fuels.

Dr. Lynn Gieger (associate professor of mathematics at Oglethorpe University) gave a talk exploring how flipped classrooms impact student attitudes and achievement in a liberal arts mathematics course.

The Joint Mathematics Meetings, the “largest mathematics meeting in the world”, is co-presented by the American Mathematical Society and the Mathematical Association of America.

Rikki Wagstrom (Metropolitan State University)

Engaging Mathematics Faculty Member Writes Chapter for New Book Published by MAA

Dr. Rikki Wagstrom, SENCER Leadership Fellow, associate professor of mathematics at Metropolitan State University, and Engaging Mathematics institutional partner, authored a chapter in the Mathematical Association of America’s recent book Doing the Scholarship of Teaching and Learning. Her chapter is titled “Using SoTL Practices to Drive Curriculum Development” and describes how SoTL, or the Scholarship of Teaching and Learning, influenced her Mathematics of Sustainability course development.

SENCER Leadership Fellow Jacqueline Dewar and Curtis D. Bennett edited Doing the Scholarship of Teaching and Learning. They provide the following commentary on Rikki’s chapter:

In this chapter, Rikki Wagstrom describes how she applied SoTL processes to aid in the development and evaluation of a new curriculum that integrated civic issues into a pre-requisite course for college algebra. She helps readers to understand several critical aspects of the process of doing SoTL by describing her approach to searching the literature and telling how her search led her to a useful model, one that prompted her to revise the site of her investigation and helped her re-shape her research question. She provides insights into the concerns that can arise in the selection of faculty to teach experimental and control sections, and the tough decisions that have to be made about how much data to collect.

For the Engaging Mathematics initiative, Rikki plans to develop four new modules for Mathematics of Sustainability. The modules will cover disappearing milkweed populations in the U.S. and the potential impact on Monarch butterfly populations, wind energy modeling and profitability, comparisons of greenhouse gas emissions generated by different automotive fuels, and the interplay between population growth in the U.S. and declining per capita carbon footprints. Each module will be a self-contained, portable unit suitable for use in college algebra, pre-calculus, and liberal arts mathematics courses.

ICM

Engaging Mathematics Advisory Board Member Co-Edits Book on Mathematical Modeling and Interdisciplinary Education

What does it take to be outstanding at mathematical modeling, and how does modeling relate to real world issues across disciplines of study? For 16 years, teams of high school students and college undergraduates have competed in the Consortium for Mathematics and Its Applications’ (COMAP’s) Interdisciplinary Contest in Modeling (ICM) to find out.

COMAP recently published a book about the contest edited by Drs. Chris Arney and Paul J. Campbell. Chris is an ICM director, United States Military Academy math professor, and advisory board member for the Engaging Mathematics initiative. In addition to co-editing the book, Chris also wrote a number of the book’s chapters. Paul is a mathematics professor at Beloit College.

The book, titled The Interdisciplinary Contest in Modeling: Culturing Interdisciplinary Problem Solving, presents a history of the ICM, including descriptions of past problems, a list of outstanding teams, and commentary from participants, advisors, judges, and directors. Also included is advice on how to prepare a team for the contest and how to develop curricula on modeling, as well as discussions on the current state of interdisciplinary education. Wm. David Burns, the executive director of NCSCE and principal investigator for Engaging Mathematics, authored one of the book’s chapters on interdisciplinarity titled “‘Multidisciplinary Trouble’ and Learning: A SENCER Approach.”

In the book’s preface, Dr. Solomon Garfunkel, the executive director of COMAP and an Engaging Mathematics affiliate, writes:

All of us who do this work [of the ICM] appreciate mathematics for its beauty. But all of us also appreciate the power of mathematics to help us understand and deal with the complexities of our world. We are educators and we want our students to see knowledge not compartmentalized into a discrete set of disciplines, but with all of its interconnections.

Making Math Relevant by Akash Kataruka

Making Math Relevant: SCI-MidAtlantic Holds Quantitative Literacy Conference at LaGuardia Community College

On October 10, 2014, over 30 mathematics educators from New York, New Jersey, and Pennsylvania gathered at LaGuardia Community College – CUNY in Long Island City, New York to hear LaGuardia faculty members present stimulating discussions on how they teach mathematics and statistics using issues that are interesting, relevant, and real to the lives of their students. Attendees came from Gannon University, Guttman Community College, Hostos Community College, Hudson County Community College, Kingsborough Community College, LaGuardia Community College, New York University, Rutgers University, and The Graduate Center, City University of New York.

The day began with warm welcomes by Drs. Paul Arcario, provost and senior vice president at LaGuardia Community College – CUNY and Mangala Kothari, professor in LaGuardia’s Mathematics, Engineering, and Computer Science Department and also a Co-PI for the National Center’s Engaging Mathematics Engaging Mathematics initiative. Their welcome was followed by an overview of SENCER and other NCSCE initiatives by Drs. Monica Devanas (SENCER Co-PI and co-director of SCI-MidAtlantic) and Ellen Mappen (NCSCE senior scholar and SENCER-ISE director).

Dr. Kothari and others emphasized the importance of developing quantitative reasoning skills while offering challenging mathematics and statistics courses that enable students to see “how they can apply their scientific knowledge and methods that they learned in class to real matters.”

All of the presentations provided good examples of rigorous, quantitatively based instruction that looks at learning through complex and important civic issues. We are happy to present to you a summary of these presentations:

• Drs. Mangala Kothari and Milena Cuellar spoke about the Engaging Mathematics project at LaGuardia and how the team is developing a statistics course based on connecting mathematics, the environment, and society. Dr. Cuellar noted that one purpose of such a course was to have students “believe that they can do math.” The course will provide students with an opportunity to learn statistics by describing how it can be applied to civic and environmental issues.
• Dr.Prahba Betne, who helped develop the NSF proposal that led to the funding of Engaging Mathematics, and who is a member of the initiative’s advisory board, followed with a presentation on how to make tables and graphs found in standard mathematics or statistics textbooks more engaging and contextual without having to develop new materials. She provided examples and discussed how she leads the class in learning these concepts by communicating information through writing and presentations that imagine real-world work situations.
• Dr. Reem Jaafar discussed using a current piece of Congressional legislation “to build students’ civic engagement and mathematical knowledge.” In her Spring 2014 college algebra course, she focused on the efforts of Senator Elizabeth Warren to reform student loans. The students first learned about the broader issue; then about interest rates and polynomial fitting. Dr. Jaafar suggested that the model can also be used to teach pre-calculus.
• Dr. Alioune Khoule led an engaging discussion of applying the SENCER approach to learning about the slope of a line in an elementary algebra course. For the lesson, students are given the rating levels of ski runs and placed into groups to think about how to measure steepness. Students then develop their own formulas to share with the class before the slope formula is even introduced.
• Dr. Shenglan Yuan discussed promoting common sense and articulated reasoning in basic skills math, moving away from the view “that mathematics is just about numbers and formulas.” She found that “by investigating real life situations,” she could “encourage independent reasoning and common sense” to solve a problem.
• Dr. Frank Wang began his presentation by speaking about “The PQL Effect”. PQL (Project Quantum Leap) was originally funded by the Fund for the Improvement of Postsecondary Education. It applied the SENCER approach to the challenges of teaching basic skills education in mathematics. Through the grant, the LaGuardia faculty used environmental, public health, and business issues to teach basic algebra and statistics courses. Dr. Wang went on to discuss teaching through Bayesian reasoning, where students infer the probability of a cause (e.g., a medical issue such as cancer) from an observed effect (e.g., a positive mammogram). Dr. Wang suggested that his students developed better numeracy and understanding of probabilities when they used Bayesian models to examine evidence in real world examples.
• Dr. Sreedevi Ande ended the presentations by describing how to teach SPSS software from a “practical perspective” in a basic statistics course. Instead of just following the SPSS manual, students brought in data on an environmental issue of importance to them and then used statistical analysis to explain the data.

“The development of core mathematical concepts is the basic challenge in enriching quantitative literacy in our students,” says Monica Devanas. “Using contexts that are relevant for students helps them build on this core as well as extend and expand their understanding to more complex mathematical areas. The SENCER approach acknowledges that students engage in mathematical thinking through a variety of ways, and the projects of the NCSCE support this effective student-centered learning model.”

SCI-MidAtlantic will be hosting another meeting on November 15 at Barnard College titled “Teaching with Technology.” Registration for this meeting is free and open to the public.

VictorDonnay of Bryn Mawr College makes mathematics engaging during 2015 SENCER Summer Institute

Mathematics Predicts Our Climate May Be Headed for a Tipping Point

Why is the climate like a billiard game? This isn’t a riddle from Alice in Wonderland, but a question Dr. Victor J. Donnay used math to help answer.

This summer, Victor, who is the William R. Kenan, Jr. Chair of Mathematics at Bryn Mawr College, worked with TED-Ed to create a short animated video on the mathematics of climate change. In the video, titled “Our Chaotic Climate,” chaotic billiard motion explains how a two-degree increase in Earth’s average temperature can lead to substantial consequences, including “more extreme and intense weather events, less predictability, and … less hospitability to human life.”

“Our Chaotic Climate” is a good example of how mathematics can help us understand the most complex and compelling civic issues of our time. Consider the video’s closing comments:

The hypothetical models that mathematicians study in detail may not always look like actual situations, but they can provide a framework and a way of thinking that can be applied to help understand the more complex problems of the real world. In this case, understanding how slight changes in the constraints impacting a system can have massive impacts gives us a greater appreciation for predicting the dangers that we cannot immediately perceive with our own senses, because once the results do become visible, it may already be too late.

In addition to creating educational videos, Victor has appeared on G-town Radio, and his Ordinary Differential Equations in Real World Situations course was selected as a SENCER Model in 2008. He currently serves as an advisory board member for NCSCE’s Engaging Mathematics initiative.

Engaging Mathematics Can Help Close a Gap in Informal Education

A blog post on the CAISE (Center for Advancement of Informal Science Education) website identified a gap in informal education, namely a lack of museum projects that address social issues grounded in math. Museums are increasingly making efforts to address social issues through their programs and exhibits. When they do so, these efforts are generally successful. Developing mathematics-based museum programs could therefore serve as a solution to the relatively low numeracy of U.S. citizens—a social issue in itself considering that many of today’s pressing problems require numerical literacy to be understood and solved.

CAISE tweeted a link to this blog post to SENCER-ISE, an initiative that supports informal science and higher education partnerships addressing social issues. SENCER-ISE in turn tweeted the link to Engaging Mathematics, knowing that the project couples social issues and math.

In the resulting social media discussion, Professor John Zobitz of Augsburg College, an Engaging Mathematics institution, wrote a response explaining how Engaging Mathematics aims “to make mathematics relevant to students’ lives, to connect mathematics learning to the goals and interests that students bring to college, and to show how mathematics relates to other disciplines, important civic questions, and technological challenges.”

In his response, Professor Zobitz welcomed the participation of museums and other informal education organizations as one way to help close the current gap. He wrote:

While the Engaging Mathematics project focuses on integration of social issues with post secondary mathematics curriculum, our hope and core belief is that it will provide a lasting impact beyond the classroom. … As we continue the work of the Engaging Mathematics initiative, we search for new avenues of collaboration or dissemination with museums and other informal science organizations. Collectively our common work broadens the number of projects that couple mathematics with social issues. We welcome the participation of museums in addressing social issues grounded in mathematics.

The original CAISE blog post was co-written by Kris Morrissey, director of the Museology Graduate Program at the University of Washington and founding editor of the journal Museums & Social Issues, and Anna Johnson, Portal to the Public Network specialist at the Pacific Science Center.

Morrissey and Johnson’s post appears in the Building Informal Science Education blog series, an NSF-funded collaboration between the University of Pittsburgh Center for Learning in Out-of-School Environments, the Science Museum of Minnesota, and the Visitor Studies Association.

We would also like to refer readers to one example of a museum dedicated to math, the MoMath, or National Museum of Mathematics, located in New York City. As the museum’s website states, the group that worked to open MoMath “quickly discovered that there was no museum of mathematics in the United States, and yet there was incredible demand for hands-on math programming.” The late Alan Friedman, who served both as project director of SENCER-ISE and director of the New York Hall of Science, was also quoted in an article describing MoMath’s foundation. He said, “There are existing museums, like the New York Hall of Science and the Liberty Science Center, and they all deal a tiny bit with mathematical concepts, but not often. To convert mathematical concepts into exhibitions requires additional work that none of the existing museums have done.” Math-focused museum programs and exhibits are indeed scarce. We hope this is something Engaging Mathematics can help work to improve.
