Exciting, Surprising, and Satisfying: Why and How to Teach
Proof, Monday, 9:00 a.m. to 10:20 a.m., Carol S.
Schumacher, Kenyon College, and Diane Herrmann,
University of Chicago. CUPM has been considering the tricky point
in the early to middle of the undergraduate mathematics curriculum
where students first encounter proof in a serious way. There are
issues of both salesmanship (This is hard. Is it really necessary?
Is it worthwhile?) and tactics (how do we help our students to learn
to engage the mathematics on their own?) Panelists will discuss
various successful strategies for helping students through this
difficult phase. Panelists include T. Christine Stevens,
Saint Louis University; Susanna S. Epps, DePaul
University; Lisa Mantini, Oklahoma State University; and

Research and Outreach Focusing on the Mathematics Education of K-8 Latino/a Students, Monday, 9:00 a.m. to 10:20 a.m., Taliesin Sutton, University of Arizona and Laura Kondek McLeman, University of Arizona. Interest in the mathematics education for underrepresented groups has grown in recent years, due in part to the discouraging results in national tests at the K-12 level (e.g., NAEP) as well as the lack of minority groups choosing to major in mathematics at the college level. Researchers from the Center for the Mathematics Education of Latino/as provide some insight into these issues as they investigate the teaching and learning of mathematics to Latino/as at the elementary and middle school level. This work focuses not only on student understanding, but also on what roles parents and teachers play in furthering Latino/a students mathematics education. The panelists will discuss their work with preservice and inservice teachers, parents, and students, focusing specifically on how language and culture impacts the mathematics education of Latino/a students. The panel includes Richard Kitchen, University of New Mexico; and Virginia Horak, Laura Kondek McLeman, Jos Mara Menndez, and Taliesin Sutton, University of Arizona.

Creating and Implementing a Capstone Course in Mathematics for Preservice Secondary Teachers, Monday, 1:00 p.m. to 2:20 p.m., David W. Dempsey, Jacksonville State University, and Matthew Winsor, University of Texas at El Paso. Reports from the MAA and NCTM indicate that as a result of changes in the way mathematics is being taught in secondary schools, teachers need a more thorough preparation in mathematics (Conference Board of Mathematical Sciences (CBMS), 2001; Leitzel, 1991; NCTM, 1991, 2000). In response to the need for improving preservice teachers content knowledge, The Mathematical Education of Teachers (MET) publication charges mathematics departments with supporting the development of a capstone course sequence for teachers in which conceptual difficulties, fundamental ideas, and techniques of high school mathematics are examined from an advanced standpoint (CBMS, 2001, p. 39). This panel session will present several examples of capstone courses that have been implemented at different universities around the nation. Panel members will discuss how they created and implemented a capstone course, give examples of mathematics from capstone courses, and present research based on their capstone course. Time will be allowed for discussion. Panelists include Edward E. Aboufadel and Rebecca Walker, Grand Valley State University; Gail Burrill, Michigan State; Henry S. Kepner, University of Wisconsin-Milwaukee, David W. Dempsey, and Matthew Winsor.

This session is cosponsored by the Mathematical Sciences Research Institute (MSRI), Institute for Pure and Applied Mathematics (IPAM), Institute for Mathematics and Its Applications (IMA), American Institute for Mathematics (AIM), and Statistical and Applied Mathematical Sciences Institute (SAMSI).
Tones Are Real Functions, Rhythms Are Sequences, Monday, 7:00 p.m. to 8:00 p.m., presented by Erich Neuwirth, University of Vienna. Musical tones (and chords) can be described mathematically as functions; the amplitude of the wave is a function of time. Therefore, real function can not only be visualized but also sonified. Rhythms, on the other hand, are discrete events and given times; therefore, a sequence of real numbers describes a rhythm. So, sequences also can be sonified. Quite a few computer tools are available to make symbolical representations of sounds and rhythms audible. In the presentation we will use some of these tools (as complex as Mathematica and as simple as a spreadsheet) to study some possibilities of the connection of mathematical concepts with auditory perception. One of the examples will be that the concept of partial sums is directly related to MIDI, a computer-based representation of music.
Becoming a Teacher of College Mathematics: Research on Mathematics Graduate Students' Professional Development, Tuesday, 9:00 a.m. to 10:20 a.m., organized by Kevin E. Charlwood, Washburn University, Larry Chrystal, University of California Irvine, and Natasha M. Speer, Michigan State University. During the past several decades there has been an increase in discussion about mathematics graduate student teaching assistants' (TAs) contributions to undergraduate instruction and their needs for teaching-related professional development. In addition to publication of resources for professional development activities and programs, educational researchers with interests in TAs have begun examining the factors that shape TAs' professional lives, their teaching practices, and their development as teachers of college mathematics. In this session several mathematics education researchers will discuss their work in this area. The session will include reports on the history of research on mathematics TAs, research on TAs' experiences as teachers, and examinations of the design of PD activities. Invited speakers will include those who have published their findings in this area. Panelists include Jason K. Belnap, Brigham Young University; Shandy Hauk, University of Northern Colorado; David E. Meel, Bowling Green State University, and Natasha M. Speer. The session is sponsored by the AMS-MAA Committee on Teaching Assistants and Part-time Instructors (TA/PTI).
A Quick Introduction to WeBWorK, a Web-Based Interactive Homework System, Tuesday, 1:00 p.m. to 2:20 p.m., Michael E. Gage, Arnold K. Pizer, and Vicki Roth, University of Rochester. WeBWorK is a program which allows students to do their mathematical homework interactively over the Web. It is currently being used by over 100 colleges, universities, and high schools in courses such as college algebra, pre-calculus to vector calculus, differential equations, linear algebra, complex variables, and statistics. WeBWorK can handle most homework problems typically used in such courses and is distributed with an extensive library of problems. With WeBWorK students get immediate feedback on the validity of their answers and have the opportunity to correct mistakes while they are still thinking about the problem. Students receive individualized versions of problems so instructors can encourage students to work together yet each student must develop an answer to their own version of the problem. Further WeBWorK provides automatic scoring of assignments. The session will provide an interactive introduction to WeBWorK. We will demonstrate how students use WeBWorK, how professors administer WeBWorK and will also discuss various assessment issues. Further information on WeBWorK and this session can be found at www.maa.org/webwork/.
Summer Research Programs, Tuesday, 2:30 p.m. to 3:50 p.m., William A. Hawkins Jr, MAA, and Robert E. Megginson, University of Michigan.
