### Gülseren Karagöz Akar

I got my B.S degree under the Department of Science Education with an emphasis on Mathematics Education from the Middle East Technical University in 1996. After graduation, I taught high school mathematics in Turkey for three years. I taught both mathematics and geometry to the 9th, 10th and 11th grades.

In 1999, I received a scholarship from the Ministry of Turkish National Education and became a graduate student at the Pennsylvania State University in 2000. During my graduate study at Penn State University, I was involved in doing research as a graduate assistant in the Mid-Atlantic Center for Mathematics Teaching and Learning (an NSF-funded collaboration of the University of Maryland, University of Delaware, and Penn State University) for several years. Also, I was involved in doing research in Exploratory Analysis of Mathematics Conceptual Learning (EAMCL) Project (an NSF funded research project) in which teaching experiments were conducted. In addition, I participated in opening a charter school, Young Scholars of Central Pennsylvania (YSCPCS), in State College in 2005. I wrote the mathematics proposal that offered the unique opportunity for State College area kids (K-6) to study the reform curriculum, Everyday Mathematics.

Currently, I am a faculty member at Boğaziçi University in Turkey. I have been teaching a methods course to prospective secondary mathematics teachers since 2008. I am currently working on a project regarding prospective secondary mathematics teachers’ pedagogical knowledge and content knowledge. In a broad sense, I am interested in studying conceptualization of mathematics and the education of prospective mathematics teachers.

### AnnaMarie Conner

I am currently an assistant professor of math education at the University of Georgia. I am interested in the interplay of teachers’ conceptions of math, teaching, and proof and their support for argumentation in their classroom teaching. Prior to my graduate studies, I taught high school math at two different schools in Virginia and Pennsylvania. While at Penn State, I enjoyed participating in research experiences with the Mid-Atlantic Center for Mathematics Teaching and Learning while taking classes in both math and math education. Interacting with the Penn State faculty was invaluable in preparing me to research and teach at UGA.

### Pete Johnson

I am a graduate of the department, starting at Penn State in 1988 in the Mathematics Department, then moving to Math Education where I was from 1991-1994, and then accepting a full-time job and FINALLY graduating with my doctorate in 2001! I am currently teaching at Eastern Connecticut State University in the Mathematics and Computer Science Department, and have been here since 2001 (prior to that I taught at Colby-Sawyer College in New London, NH from 1994-2001). I was given tenure in 2007 and was promoted to Associate Professor in 2008. I would say my research interests are in many areas of the teaching and learning of collegiate mathematics. I have done some research in the areas of motivation to learn, assessment of pre-service secondary teachers, and developmental mathematics. I have taught a wide range of classes in our department, from Elementary Algebra through Abstract Algebra. I was recently awarded a sabbatical for the Spring of 2010, when I plan to study our mathematics majors' understanding of proof.

### Brad Slonaker

Brad Slonaker earned his Ph.D. in Curriculum and Instruction with an emphasis in mathematics education from Penn State in 2004. He has been an assistant professor in the education department at Penn State Altoona College and has since moved to the mathematics department at Kutztown University. Beginning his third year as assistant professor at Kutztown in the fall of 2009, Brad teaches a combination of mathematics courses, “methods” courses and graduate level courses in mathematics education.

Brad developed his research interest, the epistemology of teaching and learning mathematics, at Penn State and the pursuit of this interest has led to many complex and fascinating professional endeavors. His dissertation entitled “Collaborative Inquiry as a Process for Developing Platform Espousal about Middle School Mathematics Education” has paved the way for several professional speaking and writing opportunities. Before entering the doctoral program at Penn State, Brad taught secondary mathematics for eleven years and obtained a Master’s of Arts in Teaching Mathematics degree from Villanova University.

### Maria A. Timmerman

As a mathematics teacher educator, I am responsible for actively engaging teachers in mathematics and teaching tasks that prompt reflection, revisiting their potentially limited conceptions of mathematical topics, and facilitating a potential reorganization of their ideas about teaching and learning mathematics. I have taught mathematics and mathematics education courses over the past 33 years. In August 1998, I completed a Ph.D. in Curriculum and Instruction specializing in mathematics education from Penn State University. I completed a Master of Arts degree in mathematics education from the University of Northern Colorado in August 1979. Majoring in mathematics, I received a Bachelor of Arts degree with Honors and teacher certification in grades 6-12 from Eastern Illinois University in May 1975.

Beginning in August 2008 to the present, I have been an Assistant Professor of Mathematics Education for the Mathematics and Computer Science Department at Longwood University, Farmville, VA. I teach mathematics content courses for prospective K-8 teachers. Our students participate in a 3-course sequence combining content and pedagogy based on the NCTM (2000) Principles and Standards for School Mathematics. In addition, I teach graduate courses for teachers enrolled in our Mathematics Specialist Masters Degree Program. My professional expertise, interests, and experiences continue to make significant contributions in the fields of mathematics education, teacher leadership, and technology.

As a graduate student at Penn State University (1991-1997), I held positions of graduate research assistant and teaching assistant for both elementary and middle/secondary mathematics education methods courses. I supervised prospective elementary/middle school teachers’ mid-level field experiences each semester. To challenge my perspective of the reality of an elementary classroom, I took on the role of a second-grade mathematics teacher through a one-semester teaching internship in fall 1993.

If you have questions about my Penn State experiences, please contact me at timmermanma@longwood.edu.

### Jean Werner

After graduating from Indiana University of Pennsylvania, I went to Penn State for graduate work. I graduated with a MA in Mathematics from Penn State in 1967. I got married and stayed home with my two children for 5 years. I then took part time work teaching at Mansfield University in the Mathematics department and observing student teachers until 1980. I then went to work as a computer consultant for Corning Incorporated for seven years. At this time a temporary position in the Math department at MU opened up. I got this job and had it for two years when they told me that in order to keep my job I needed to get a PhD. I went to Penn State evenings and summers while I was teaching at MU until I got a PhD in 1995 and I then continued teaching at MU until I retired in 2003. The experiences I had working with the very supportive faculty and fellow students while I attended Penn State will always be very special to me. In retirement, I now spend my spare time painting, sculpting. reading, traveling, and enjoying my grandchildren. Do I miss teaching and doing mathematics? YES.

My e-mail address is jswerner@hotmail.com
