*Thursday, August 1, 1:00 p.m. – 4:55 p.m., Connecticut Convention Center, Room 14*

Online education is becoming increasingly common, and many institutions desire to offer courses online. Some faculty members are tasked with developing and teaching online courses without adequate training for doing so effectively. This session seeks to share ideas to help instructors of online courses. The focus will be on teaching courses completely online, rather than using online tools to augment a face-to-face class. Possible topics include strategies for delivering content, engaging students, fostering discussion and collaboration, and assessment in an online environment. Presentations about particular technologies useful for online classes are also welcome.

This session invites presenters to share their favorite undergraduate geometry proofs. These proofs should be suitable for Euclidean and non-Euclidean geometry courses as well as for courses frequently referred to as “modern” or “higher” geometry but not those related to differential geometry or (low-level) graduate courses. Proofs must be for theorems other than the Pythagorean Theorem. Presenters must do the full proof, discuss how the proof fits into the course, provide information regarding prerequisite topics for the proof, and discuss associated areas with which students have difficulty and how such concerns are addressed so that students understand the proof. Presenters are invited to discuss how they have modified the proof over time as well as to share historical information for “classic” proofs and explorations/demonstrations that they use to help students understand the associated theorem. Abstracts should include the theorem to be proved/discussed as well as brief background information.

In many mathematics classrooms, doing mathematics means following the rules dictated by the teacher and knowing mathematics means remembering and applying these rules. However, an inquiry-based learning (IBL) approach challenges students to create/discover mathematics. Boiled down to its essence, IBL is a method of teaching that engages students in sense-making activities. Students are given tasks requiring them to conjecture, experiment, explore, and solve problems. Rather than showing facts or a clear, smooth path to a solution, the instructor guides students via well-crafted problems through an adventure in mathematical discovery. The talks in this session will focus on IBL best practices. We seek both novel ideas and effective approaches to IBL. Claims made should be supported by data (student responses, test scores, survey results, etc.) or anecdotal evidence. This session will be of interest to instructors new to IBL, as well as seasoned practitioners looking for new ideas.

This session will highlight research results of projects that either were conducted by undergraduates or were collaborations between undergraduates and their faculty mentors. Of particular interest are those collaborations that involve students and faculty from both mathematics and biology. As many institutions have started undergraduate research programs in this area frequently with the help of initial external funding, the session is interested in the process and logistics of starting a program and maintaining a program even after the initial funding expires. Important issues include faculty development and interdisciplinary collaboration, student preparation and selection, the structure of research programs, the acquisition of resources to support the program, and the subsequent achievements of students who participate in undergraduate research in mathematical and computational biology.

The session will also feature undergraduate research projects in mathematical and computational biology which are mentored by a single faculty mentor without the support of a larger program. We seek scholarly papers that present results from undergraduate research projects in mathematical or computational biology, discuss the creation, maintenance, or achievements of an undergraduate research program, or describe the establishment or maintenance of collaborations between faculty and students in mathematics and biology.

The goal of this contributed paper session is to share appropriate problems, course descriptions, and other opportunities designed to support and encourage small research project in mathematics at the high school and community college level. Presentations that focus on examples of good problems, experiences with recruitment of students, support for both faculty and students, and presentation and publication of results are encouraged.

In 2012 there were approximately 27,000 students who took BC Calculus before entering the 12th grade. For these students, a standard course in Differential Equations, Multivariable Calculus, or Linear Algebra may be offered at their school, a local community college or university, or on- line. While these may be good courses, they do not offer high-level investigative experiences emphasizing the creative aspects of mathematical discovery, which encourages continued study in mathematics.

Encouraging students to use their own mind is absolutely essential when working with students who are talented and interested in mathematics. Students must be working on problems that are sufficiently rich to allow for extended work on them and sufficiently interesting and engaging so that they are willing to give the problems their time and intellectual energy. Small researchable problems offer this challenge to student creativity.

As with all mathematics, recreational mathematics continues to expand through the solution of new problems and the development of novel solutions to old problems. For the purposes of this session, the definition of recreational mathematics will be a broad one. The primary guideline used to determine the suitability of a paper will be the understandability of the mathematics. Papers submitted to this session should be accessible to undergraduate students. Novel applications as well as new approaches to old problems are welcome. Examples of use of the material in the undergraduate classroom are encouraged.

A common focus of university administration is student retention and graduation. First year mathematics courses, both general education and major specific, have comparatively high drop/fail/withdraw rates. This means that they are often scrutinized in regard to their effect on retention and graduation rates. In this session, we would like to hear what you have been doing to respond to this scrutiny. We hope to focus on departmental-wide efforts, rather than specific classroom approaches. Presentations could include complete course redesign, co-requisite support courses, restructure of curriculum, departmental efforts to standardize, etc. Note that we would like to hear about successful, in process, and unsuccessful initiatives. Presentations that include a description of the initiative along with data supporting the success or failure of these initiatives are especially encouraged.

A math circle is broadly defined as a sustained enrichment experience that brings mathematics professionals in direct contact with pre-college students and/or their teachers. Circles foster passion and excitement for deep mathematics. The SIGMAA on Math Circles for Students and Teachers (SIGMAA MCST) supports MAA members who share an interest in initiating and coordinating math circles.

SIGMAA MCST invites speakers to report on best practices in math circles with which they are or have been associated. Talks could address effective organizational strategies, successful math circle presentations, or innovative activities for students, for instance. Ideally, talks in this session will equip individuals currently involved in a math circle with ideas for improving some aspect of their circle, while also inspiring listeners who have only begun to consider math circles.

Students who wish to present at the MAA Student Paper Sessions at MathFest 2013 in Hartford must be sponsored by a faculty advisor familiar with the work to be presented. Some funding to cover costs (up to $750) for student presenters is available. At most one student from each institution or REU can receive full funding; additional such students may be funded at a lower rate. All presenters are expected to take full part in the meeting and attend indicated activities sponsored for students on all three days of the conference. Abstracts and student travel grant applications should be submitted at www.maa.org/mathfest/abstracts. For additional information visit www.maa.org/students/undergrad.
