A Tribute to Anja S. Greer

Were it not for Anja S. Greer's influence and inspiration, there wouldn't be a Mathematics and Technology Conference today. After returning from a week-long conference on Pascal programming, Anja, a member of the mathematics department, decided that Exeter could host a similar conference. She enlisted the help of many others in and out of the mathematics department, and in the summer of 1985 the first Conference on Secondary School Mathematics and Computers at Phillips Exeter Academy was held. Subsequently the name of the conference was changed to the Conference on Secondary School Mathematics and Technology, as calculators made their appearance. To honor Anja's inspiration, vision and courage, the conference was renamed in the summer of 1997 to the Anja S. Greer Conference on Secondary School Mathematics and Technology. In April of 1998, Anja Greer lost her battle with breast cancer.

We are honored to continue her legacy.

Stephen Maurer, Swarthmore College


The primary focus of the conference will be participation in two seminar groups. The seminars will meet for two hours each day, will be limited to fifteen people, and will be led by teachers who are experienced in using computer materials in the classrooms.

1. Algebra/Getting Started
This seminar is for those who have yet to make much use of the computer in their teaching. Participants will develop worksheets which explore mathematical ideas using simple BASIC programs. The objective will be to integrate this material into the participant′s own curricular structure. Topics from algebra and precalculus will be used. Leader: Bill Campbell (Phillips Exeter Academy)

2. Geometry/LOGO
The use of LOGO with young children is well known; it is being used increasingly often with high school students for exploring geometry and teaching a structured approach to problem solving. This seminar will present materials appropriate for a standard high school geometry course. Leader: Joseph Aieta (Weston High School)

3. Geometry/"Geometric Supposer"
"The Geometric Supposer" is a commercially available software item, co-developed by guest speakers Judah Schwartz and Michal Yersushalmy, which offers exciting opportunities for conjecturing. This seminar will present one teacher′s approach to incorporating "The Geometric Supposer" into a standard high school geometry course. Leader: Richard Houde(Weston High School)

4. General Mathematics
The computer makes possible some alternatives to the typical computation-oriented general mathematics courses in secondary school. This seminar will make use of spreadsheets and data processing software to facilitate students′ capabilities with practical applied mathematics and to improve their mathematical thinking and problem solving skills. Leader: Mary Kay Corbitt (Louisiana State University)

5. Pre-Calculus/Elementary Functions
The computer will be used to develop many topics from the standard algebra and pre-calculus curriculum: solutions to equations, graphing elementary functions, sequences, series, trigonometry, limits, matrices, and so forth. Teacher-designed programs will be demonstrated as well as commercial software such as muMath, TK-Solver, Green Globs, and Graph Guesser. Leader: Jon Choate (Groton School)

6. Teacher Authoring
Participants will create a computer-assisted lesson of their own choice, using the authoring language SUPERPILOT. Designed for educators, this language facilitates the production of graphics, music, and animation. It allows for the mixing of graphics and text and the use of small and large fonts. Leader:Barbara Singer (University of Massachusetts)

7. Mathematical Modeling
The power of mathematics to describe and explain the real world is vividly demonstrated through the use of computer simulation models, in which discrete approximations to continuous functions permit realism without the use of calculus. Participants will learn to build models as well as to use existing models in their teaching. Models will be selected to demonstrate the wide variety of application areas appropriate for simulation. Leaders: Jennifer Kemeny(M.I.T) and David Myers (Winsor School)

8. Mathematical Investigations
Mathematical investigations provide an opportunity for students to do mathematics, to ask questions and try things, to look for patterns and relationships, to make and test hypotheses, to generalize and apply what they find to other situations. This seminar will use commercial spreadsheets, MicroWorlds, and graphing utility. Leaders: Tim Barclay (Technical Education Research Centers)

9. Potpourri
Offered primarily for those teachers who would rather write their own software, this seminar will present one teacher′s attempts to stimulate his students mathematically using the computer as a natural resource. Example will be provided at all levels, and it is hoped that participants will bring ideas to share. Leader:Richard Parris (Phillips Exeter Academy)

10. Calculus
This seminar will focus on the use of the computer as a tool for conceptual development of introductory calculus. Participants will explore strategies for using tool-kit and symbol-manipulation programs (muMath) in the teaching of the subject. Leader: Kathleen Heid (Penn State University)

11. Contemporary Algorithmic Mathematics
A contemporary emphasis in mathematics, both in research and in college teaching, is on algorithmic thinking - not only to compute answers, but also to suggest problems and even to do proofs. This theme will be illustrated with material appropriate at the secondary level, such as sequences and series, linear equations, and graph theory. Leader: Stephen Maurer (Swarthmore College)

12. Probability
A Digital PDP 11/44 and the BASIC language will be used to simulate problems which can be solved theoretically in a one-semester high school course. Simulations include random walks, waiting-time problems, the "gambler′s ruin" game, and shuffling cards, as well as other simple problems with difficult solutions. The participant needs to know very little about probability. Leader: Spruill Kilgore (Phillips Exeter Academy)

13. Linear Algebra
This seminar will investigate how the computer might be used to enhance the understanding of the fundamental concepts of linear algebra and to investigate certain realistic applications. Topics to be considered are: vectors, vector spaces, and three-dimensional transformations. The seminar will use LOGO and IBM PCs. Leaders: Philip G. Lewis (Lincoln-Sudbury High School) and Alison Birch (Phoenix School)

13. Statistics
This seminar will explore the use of the computer to crunch numbers and to facilitate statistical computations. Topics will include measures of central tendency, standard deviation, confidence intervals, line of best fit, and chi-square tests. Leader: To be determined
