Nancy Hagelgans, Chair, MAA Committee on Sections, Ursinus College
Gave a Texas NExT Invited Address entitled "Coorperative learning in undergraduate mathematics classes" on Friday, April 4, 2008, at 9:00 a.m. in the Thompson Student Center, Room 130.
Abstract: Cooperative learning is a method of active learning in which stable groups of students produce a significant amount of work in a course. Their work is assessed and counted in the course grade. She discussed formation of student groups, initial activities for groups, groups in the classroom and computer lab, assignments outside class, difficulties with groups, monitoring the groups, modes of operation within groups, assessment in the courses, and group testing, Courses considered include Mathematics for the Liberal Arts, Calculus with Review, Calculus I-III, Discrete Mathematics, Abstract Algebra, and Topology.
She also gave an invited address entitled "Planar Linkages" on Saturday, April 5, 2008, from 10:30 – 11:20 in the Fine Arts Center Auditorium.
Abstract: A planar linkage is constructed in the plane from rigid links or rods that are connected with movable joints at their ends. Robot arms and carpenters’ rulers are examples of planar linkages in which the links are connected to form a chain. She examined the reachability regions of robot arms, which are chains with one fixed end. Then she went on to solve the minimal folding problem of carpenters’ rulers with links of different lengths. Finally, she addressed some planar linkages that can be used to convert one type of motion to another type of motion.

She also gave an invited address entitled "Good news Everyone! Mathematical Morsels from The Simpsons and Futurama" on Friday, April 4, 2008, at 7:00 p.m. in the Agave Banquet Room (“City Hall”).
Abstract: Did you know that The Simpsons and Futurama contain hundreds of humorous mathematical and scientific references? What curious mathematical object is used as a bottle for beer in the 31st century? What is a Frinkahedron? What is the significance of the number 1729? The only prerequisite for this talk was an open mind!
She explored the mathematical content and educational value of some favorite moments along with the motivations and backgrounds of the writers during an interactive talk. Popular culture can reveal, reflect, and even shape how society views mathematics, and with careful consideration of the benefits and challenges, these programs could be an ideal source of fun ways to introduce important concepts and to reduce math anxiety. In the process she looked at related, recent work in geometry and computational number theory. For more information, check out SimpsonsMath and FuturamaMath.
Biography: Sarah J. Greenwald is an Associate Professor of Mathematics and a Women’s Studies core faculty member at Appalachian State University. She received her PhD from the University of Pennsylvania.

She co-created the educational website SimpsonsMath.com with Andrew Nestler. While it is not affiliated with the show, the site was mentioned in the audio commentary of the 7th season of The Simpsons. Her interactive mathematics lecture appears as a 25-minute DVD extra for the 20th Century Fox Futurama movie Bender’s Big Score and is listed as “Mind-bending.” Dr. Greenwald has spoken about the impacts of scientific popular culture representations on NPR’s Science Friday and all over the country.
Robert W. Vallin, Associate Director for Student Programs at the Mathematical Association of America
Gave the student forum talk entitled "An Introduction to Voting Theory" on Friday, April 4, 2008, from 11:00 – 11:50 in the Thompson Student Center, Ballroom A.
Abstract: As of late, mathematics is making several inroads into the social sciences. Dissecting how decisions are made and finding the best choices are the focus of fair division, game theory, and voting theory. This talk introduced voting with a preference ballot and various schemes available to use with these ballots, including applying these methods to a real election. Additionally, he discussed what makes a “fair voting method” and, the effect of insincere voters trying to manipulate the outcome.

Dr. Marilyn Carlson, Director, Center for Research on Education in Science, Mathematics, Engineering and Technology, Arizona State University
Gave an invited address entitled "Preparing Students for Success in Calculus: Research Insights and The Precalculus Concept Assessment (PCA) Instrument." on Saturday, April 5, 2008, in the Fine Arts Center Auditorium.
Abstract: Precalculus level curriculum has not supported students in acquiring the reasoning abilities and understandings needed for success in beginning calculus. The session addressed issues that contribute to this situation. Research findings that reveal the ways of thinking and understandings students need for success in beginning calculus were discussed. These findings were contrasted with results from studies that have revealed the understandings that high performing precalculus level students’ hold.
Finally, a research-developed Precalculus Concept Assessment (PCA) instrument that assesses students’ readiness for beginning calculus was shared.
Here are some pictures I took of the festivities as "official photographer" of the meeting. Enjoy!
This year concludes my tenure as official Texas Section photographer. It also marks my 40th consecutive meeting to attend.
At the banquet, I was presented the plaque at the left comemorating this achlevement for which I am very grateful. I was fortunate to have been in good health in March and April during the years from 1969 to 2008. Over the years, I have traveled to Texarkana, Lubbock twice, San Angelo, Edinburg, Beaumont and a great number of places in between.
I would like to encourage you young people just starting to attend the Texas Section meetings to commit yourself to the goal of breaking my longevity record in 2048 when you attend your 41st consecutive meeting. I hope some of you already have a head start.
I would like to thank Dr. Dale Bedgood, department head at ETSU from 1967 to 1988, for encouraging me and other mathematics faculty to attend the Texas Section meetings. I would also like to thank Dr. Stuart Anderson, department head at ETSU from 1988 to 2003 and secretary of the Texas section, for encouraging me and other mathematics faculty to attend the Texas Section meetings and encouraging me to continue to attend after my retirement in 1996. He "hired" me to be the "official" Texas Section photographer which I have enjoyed doing for the last several years.
I have also enjoyed putting together these Texas Section Meetings' websites each year and hope you have enjoyed reliving the meetings through text and pictures over the years. Good luck on your future meetings. It won't be long until we celebrate our 100th anniversary in 2020. I hope I am still around to come to it. Please have it close by.
