The purpose of this project was to develop and field test supplementary mathematics curriculum materials that could be used in a typical school setting to introduce elementary school children to calculators and computers in the process of solving everyday mathematical problems. The materials were designed to help teachers: (1) familiarize children with the technology and promote its spontaneous and competent utilization; (2) foster the appropriate applications of technology; (3) encourage and instill positive attitudes toward technology on the part of children; and (4) teach traditional and non-traditional mathematical topics more effectively. Part 1 is the final report from the project director and includes the purpose, the outline of the procedures, the results, the end products, and conclusive recommendations. Part 2 contains the final evaluation reports from four different sites in the United States that participated in this project: New Rochelle, Brooklyn, and Newburgh, New York; and Tucson, Arizona. Each final evaluation report contains an introduction, a pre-service workshop description, notes on the supplementary lessons, calculator lessons, and computer lessons, a synopsis of student growth in terms of achievement gains and attitude changes, and the impediments to implementation that were encountered. Part 3 consists of appendices which include a workshop evaluation form, a lesson evaluation form, a teacher interview encountered. Part 3 consists of appendices which include a workshop computer and calculator applications tests, and student attitude surveys about the technology utilized. (JJK)
