*Zometool Workshops, Geometry Barn Raisings, and Projects Organized*

- "A STEAM-Powered Adventure at the Quick Center," July 31 & August 1, 2017. I ran the Zometool workshops in this two-day collaborative art, science and math experience for 5th- and 6th-grade students and teachers in the Bolivar-Richburg school district.
- Zometool Camp at SBU, June 26–29, 2017. Twelve students, ages 9–13, made 2- and 3-dimensional challenges, worked together to construct a large geodesic dome, competed to see who could make the best “spinner,” worked together to assemble a 7,200-piece work of “mathematical art” called a cantellated hypericosahedron, and made splendid projects of their own design.
- Two Zometool workshops during Creative Arts Day at Coudersport Jr. Sr. High School in Coudersport, PA, on February 24, 2017. High school students explored art and mathematics by building tessellations with Zometool.
- Zometool workshop at the Challenger Learning Center of the Twin Tier Region, during the "Space Dreamers" Science Camp for 3rd-6th graders on February 21, 2017. The students built, among other projects, a large geodesic dome which was incorporated into their "Moon base."
- "Zometool as a STEAM Educational Tool," a Zometool workshop at the 2016 Art Teacher Professional Development Day at the Quick Center for the Arts, St. Bonaventure University, October 6, 2016.
- The Zometool Club at Southern Tier Catholic School, fall 2016–spring 2017.
- Zometool Camp at SBU, June 27–30, 2016.
- A geometry barn raising with Allegany-Limestone Central School — Spring 2016. On May 20 and 24, 2016, Linda Dodd-Nagel's 66 8th-grade students built a three-dimensional "shadow" of a four-dimensional figure called a runcitruncated hypericosahedron.
- The Connect 4 Project, which involved 87 middle school students from the Allegany-Limestone, Hinsdale, Olean, and Portville school districts working together to build the world's first stage-6 Sierpinski tetrahedron made from Zometool. The structure stands 13 feet tall and contains 32,770 parts. The project was completed on the stage in the Quick Center for Arts on May 7, 2015.
- Zometool Workshop at the Challenger Learning Center of the Twin Tier Region, during the Space Dreamers Winter Camp for 4th-7th graders, February 17, 2015.

*Additional Accomplishments*

- Hill, C. (July, 1999). Uniform distribution modulo one on subsequences,

My goals as a teacher are to help students become independent thinkers and to help them develop the skills and the confidence needed to tackle challenging problems. Accordingly, my philosophy of teaching is characterized by the Socratic method, small-group work, and problem-solving strategies.

When the instructor poses questions to his or her students, be it in class or during office hours, the students become active, rather than passive, participants in their learning. During office hours, an instructor can tailor the questions to the needs of a particular student. The instructor’s queries can be designed so that it is the *student*who discovers the key that unlocks the problem at hand. I've observed again and again that students are capable of more than they realize.

An instructor can ask only so many questions during the lecture. Inevitably, most of the time most of the students are not involved in the discussion. Small-group work is a way for nearly all of the students to be active participants in their learning nearly all of the time. As students work together in groups of about three on a worksheet or project, they are providing themselves with examples, making mistakes without being penalized, talking mathematics, and meeting their classmates.

Every problem contains within it a lesson. Author Richard Bach puts it this way: *There is no such thing as a problem without a gift for you in its hands. You seek problems because you need their gifts.* The lessons lurking within a mathematics problem are the principles that we apply to solve the problem, whose utility extends to countless other problems. These “gifts” are called *problem-solving strategies*. Although students encounter a vast number of problems during a mathematics course, only a small number of problem-solving strategies, in conjunction with basic knowledge of course material, are required to tackle almost all of them. By unlocking so many problems simultaneously, problem-solving strategies help to demystify mathematics. I strive to point out key strategies as they arise in the problems that I work for my students.

I am deeply interested in community outreach. I have organized several Zometool workshops, "geometry barn raisings," and projects with middle school and high school students and am looking for opportunities to do more. For more information, please see my webpage of Zometool Resources.

To promote mathematical problem-solving at St. Bonaventure, I created and teach MATH 281. The Problem Solving Seminar, run the Bona's Bonus Problems Program, and act as the local supervisor for the Putnam Mathematics Competition and the University of Rochester Mathematical Olympiad.

Dr. Jeff Peterson, Dr. Denny Wilkins, and I have worked on an extended project on improving the quantitative literacy of students at St Bonaventure University. In particular, we studied the effectiveness of the quantitative reasoning requirement in the Clare College curriculum (the core curriculum of St. Bonaventure). Our project was funded by 2006/2007 and 2007/2008 Martine Grants. In the spring of 2013, we created a new course, MATH 135. Quantitative Reasoning, which is a foundational course in quantitative literacy.

I'm fascinated by the visual presentation of information, so I often pursue projects and activities that may be characterized in this way. For example, I organize the Arts & Sciences Exposition, I created and maintain the website for *The Laurel* (St. Bonaventure's campus literary magazine), and I'm the principal academic web editor for the university. I love cinema and I'm *gradually* learning American Sign Language.
