**George Ashline**, chair and professor of mathematics, during the week of July 21-25 co-taught the course *Number Theory for Teachers* as part of the Vermont Mathematics Initiative (VMI). The VMI is a three-year, statewide, comprehensive professional development program in mathematics for Vermont teachers to prepare them to become highly effective mathematics instructors with strong mathematics content knowledge, problem-solving skills, and leadership skills. Thirty elementary, middle-level, and high-school teachers from across the state were actively engaged in the week-long course. **On June 23 and 24**, George engaged a group of more than 30 Vermont high school students in the presentation "Estimating the Circumference of the Earth – Following in the Shadow of Eratosthenes" as part of the Governor's Institute of Vermont Mathematics Institute, a week-long summer program for outstanding high school students, held at the University of Vermont. **On June 9,** George presented "Correlation Properties and Applications" to one AP class and "Exponential Functions in Snowflakes, Carpets, and Paper Folding" to two other math classes at Brattleboro High School. Through several activities in the first workshop, George led investigations by students of the definition and properties of the correlation coefficient and lines of best fit for pairs of quantitative variables. In the second workshop, students explored exponential functions and their applications and the "Chaos Game." These presentations and visits were sponsored by the Vermont State Mathematics Coalition's "Expanding Horizons Program," through which college and university faculty are invited to give presentations and visit classrooms across the state of Vermont. **During Spring Break week**, George gave three invited talks/workshops to different classes/groups of students at Canaan High School in Canaan, Vt. He presented the workshop "Exponential Functions in Snowflakes, Carpets, and Paper Folding" to one Pre-Calculus/Calculus II combined class, followed by an Algebra I class, followed by an Eighth Grade math class. Later during Spring Break, George gave four invited talks/workshops to different classes/groups of students at Milton High School in Milton, Vermont. He presented "Bias and Margin of Error in Statistical Analysis" to two AP Statistics classes, followed by the workshop "Exponential Functions in Snowflakes, Carpets, and Paper Folding" to three Pre-Calculus classes and another version of that workshop to an AP Calculus class. Through several hands-on activities in each workshop, George led investigations by students at those two high schools of relevant concepts in Mathematics and Statistics. These visits were sponsored by the Vermont State Mathematics Coalition's "Expanding Horizons Program," through which college and university faculty are invited to give presentations and visit classrooms across the state of Vermont.

**George Ashline,** professor and chair of mathematics, was again this year a faculty consultant at the 2012 Advanced Placement (AP) Calculus Readings, held June 8-16 in Kansas City. Representing various universities, colleges, and high schools from around the world, faculty consultants graded the free response portions of over 360,000 AP Calculus exams during the week-long reading. George served as a table leader at the reading, helping to facilitate the assessment work of a group of fourteen readers.

**George Ashline,** professor and chair of mathematics, on May 15, 2011 presented "Correlation Properties and Applications" to several high school mathematics classes at Bellows Free Academy High School in Fairfax, VT. Through several activities, George led investigations by students of the definition and properties of the correlation coefficient and lines of best fit for pairs of quantitative variables. This presentation was sponsored by the Vermont State Mathematics Coalition's "Expanding Horizons Program," through which college and university faculty are invited to give presentations and visit classrooms across the state of Vermont. Also, with several co-authors, George recently had an article accepted for publication as one chapter of the current NCTM yearbook. Here are the details of the publication: "Closing the Achievement Gap: Systemic Collaboration for Equity in Mathematics," (with Marny Frantz, Kendra Gorton, Sandy Hepp, and Stephanie Ratmeyer), In J. Bay-Williams and W. Speer (Eds.), *Professional Collaborations in Mathematics Teaching and Learning: Seeking Success for All*, NCTM 74th Yearbook, NCTM: Reston, VA (2012) 31-45. Also, George and Dave Landers, Instructor of Psychology, presented in an "Approaches to Learning with Tegrity" showcase November 29, 2011 at the campus Technology Center. Also, their presentations along with their students were recorded (via Tegrity, naturally) with the intent of making the recording available to the community via a Web site link thanks to the work of Jim Millard, senior instructional technologist. Over lunch, Dave and George and some of their students held a discussion of their experiences using Tegrity in a classroom setting, and how this technology tool has enriched classroom pedagogy and supported student learning. Dave and his students talked about peer and self-review in Sports Psychology, as well as how Tegrity is used for observation in Theory of Psychology. George uses Tegrity, clickers, and the Smartboard to help his students understand, apply, and review mathematical concepts in such classes as Calculus and Linear Algebra. Examples of successful Tegrity captures and some features of this technology were shared.
