The Annual Meeting of the Texas Sectionof the Mathematical Association of Americaat |

in Arlington, Texas on April 14-16, 2005 |

## The Texas Section of the MAA held its 2005 annual meeting in Arlington, Texas on April 14, 15 and 16, 2005 on the campus of The University of Texas at Arlington. |

The program of events scheduled at this meeting was exciting, in formative, and different. One of the innovations adding interest this year was the Calculus Bowl for students on Thursday evening. It attracted enthusiastic participants from all over the state. Also, because of the recent record-breaking number of student contributed papers, the student paper sessions were moved to Friday morning. This allowed for fewer competing sessions and more opportunity for faculty to attend student presentations. Finally, a conference luncheon was held on Friday at noon.

CONTRIBUTED PRESENTATIONS:

Research. expository, and pedagogical papers, technology presentations, and demonstrations were presented. There were special sessions for student presentations, as well as Texas NExT research papers.

SPEAKERS:

Several of the invited addresses provided an outstanding program at the University of Texas at Arlington. Keynote addresses were presented by Arlie Petters, Duke University, Martin Isaacs, University of Wisconsin, Italo Simonelli, Texas A&M-Comnmerce, Cora Sadovsky, Howard University and Carl Cowen, MAA President. Other speakers, panels and activities rounded out a full and interesting program for members, students, Texas NExT fellows, and department chairs.

## Carl Cowen, MAA President, was born and raised mostly in Indiana. He was educated at Hanover College, Indiana University, the University of War (England), and received the Ph.D. in pure mathematics from the University of California, Berkeley. He was at Purdue University from 1978 to 2004, but before that had a post-doctoral position at the University of Illinois and teaching experience in junior high school and small colleges. |

He was Director of Purdue’s Actuarial Science Program from 1992 to 1997 and was Head of Purdue’s Mathematics Department from 1997 to 2002. Since August 2004, he has been Dean of the School of Science at IUPUI (Indiana University - Purdue University at Indianapolis) where he promotes research and education at this rapidly developing young institution.

His primary research interests have been in operator theory and complex analysis, specifically, studying operators on a space of analytic functions given by composition with fixed functions. His primary pedagogical interests have been in teaching linear algebra, both to math majors and to engineering students. He has directed about 25 undergraduate students in research mostly on topics in linear algebra, and has supervised several Ph.D. students. In 2002-03, Dr. Cowan spent a sabbatical year at the Mathematical Biosciences Institute at The Ohio State University, turning his research attention to the mathematics of neuroscience. Last year he worked with biologists at Purdue to develop a mathematical model of parts of the sensory system of the medicinal leech and to develop and teach a course on computational neuroscience for senior mathematics and biology majors.

OF INTEREST TO STUDENTS

The Texas Section welcomed all students to this year’s meeting. There were over flfty students who presented contributed papers. A highlight of the meeting was the Calculus Bowl for students on Thursday evening. All of the invited addresses, especially the student forum, were of interest to students. The annual student pizza and puzzle party was a popular event. There was a breakfast meeting for students and MAA student chapter advisors, and an opportunity to meet students and faculty from other campuses. Students could also browse through the interesting exhibits offered by publishers, software and hardware vendors, and others. There was no registration fee for students and the pizza party was free too!

TEXAS SECTION PROJECT NExT

The Texas NExT (New Experiences in Teaching) program is now in its tenth year of operation. This program, sponsored by the MAA with support from the Exxon Education Foundation, is designed to help new mathematics faculty in Texas be more successful. Dr. Montie Monzingo, Southern Methodist University. is the director of the Texas NExT program.

Special activities for Texas Project NExT Fellows were scheduled for Thursday evening, April 14, and Friday morning, April 15. For the remainder of the meeting. Texas Project NExT Fellows participated in the regularly scheduled activities of the Annual Meeting.

If you know a new faculty member in Texas, please encourage them to become involved. A Texas NExT web page can be found at faculty.smu.edu/mmonzing/texnext.html. An application form is available there. We appreciate the work of Dr. Monzingo, and the support of the Exxon Education Foundation. The activities do much to further mathematics and mathematics education in Texas.

Distinguished Teaching Award

## Dr. John Quintanilla, Associate Professor at the University of North Texas, has received the 2005 Texas Section College Distinguished College or University Teaching Award. When John first arrived at UNT about 8.5 years ago, it was clear then how seriously he took his teaching responsibilities. One of the distinguishing characteristics of John’s teaching is his ability to include illuminating and interesting real examples in his class. I I does this in two ways. First, he uses applied examples in his lectures to make the material more concrete. Second, he assigns challenging projects that are based on real applications. |

Students leaving John’s class have a very good sense of how the concepts taught in class are actually used. John devotes a great deal of time and effort to the Texas Academy of Mathematics and Science (TAMS). The fact that he requests to teach TAMS classes every year indicates his strong commitment to this program. In their first year, most TAMS students take a five-hour Pre-calculus course, followed by a four hour Calculus I course. As his teaching load is two courses per semester, he willingly teaches three extra hours each year. He also volunteers to help students move in, he is completely responsible for the placement of students in their first math classes, and he is on the TAMS Selection Committee.

Good teachers either care about their students or care about the subject matter. Great teachers, such as John, care deeply about both. lie invests extra time and effort to show his students that he values them as humans. For example, he learns all his student’s names by the second day of class, he helps with special events, and he invites groups of students to dinner.

John’s student evaluations are outstanding. His student evaluations have been among the highest in the department for several years. This is especially impressive since John often teaches Math 1680, an introductory statistics course for non-majors that often results in low student evaluations for other instructors. Dr. Quintanilla won the University of North Texas President’s Council Teaching Award in Spring, 2004. In his application for that award, several letters form his former students were included. Each of the students had nothing but praise for Dr. Qunitanilla’s teaching.

John Quintinalla received his BS and MS from Stanford University in 1992. He received a MA in 1994 and PhD in 1997 in Civil Engineering at Princeton University.

Members of the Selection Committee are Professor John Sieben, Texas Lutheran University, Chair; Professor Don Edwards, Texas Women’s University; Professor Rhonda Hatcher, Texas Christian University; Professor Edwin Hewit, Hardin-Simmons University; Randal Hoppens, Blinn College.
