Teacher Training Institute (TTI) 1986 - 89, with William J. McKeough, for 60 exemplary local high school teachers. Graduate course work in Mathematics, Computers and Mathematics Education included traditional areas as well as much that was new or soon to be introduced into the high school curriculum across the country: History of Mathematics, Problem solving via Pascal, mathematical modeling on the computer, software in the classroom via spreadsheets, enrichment topics for secondary mathematics, Discrete Mathematics, Data Structures in Pascal, and the elements of Calculus. This intensive program featured students working in teams and participants acting as coaches. It was conducted in a family atmosphere with special events during its two-and-a-half year period of course offerings (guest lectures, graduation ceremonies) and follow-through events (Math Day, Reunion and Mini-Conference and an experimental course for program graduates and their gifted students called Number Theory and the Computer ) during the one-year wind-down period. A dissemination packet of 9 booklets describing the Institute s creation, syllabi, program content and experiences was distributed to Institute members and other interested educators on the high school and college levels.

Leadership in Middle Grade Mathematics (LIMM), 1992 - 97, with William J. McKeough and Sharon Whitton, for teachers of grades 5 - 8. Building on the strengths of the previous TTI program, this project brought together 65 exemplary teachers for innovative course work based on the NCTM Standards and special events in Geometry, Number Theory, Problem Solving, Math History, Discrete Mathematics, graphing calculators, emerging software, and recent issues and techniques in mathematics education. Participants created leadership projects to multiply the program s effects and the entire project concluded with a conference held at Hofstra and the dissemination of the LIMM Handbook.
