Integrating Graphical, Numerical, and Analytical (GNA) Approaches in Community College Mathematics Offerings Using Palmtop Computers & Graphing Calculators

该项目将图形、数值和分析（GNA）方法整合到阿迪朗达克社区学院的各级数学课程中，通过使用带有派生计算器和图形计算器的手持式掌上电脑教室。阿迪朗达克大学的试点项目表明，将传统的数学课堂转变为一个活跃的实验室环境是有可能的，学生们可以合作探索概念和现实世界的问题。该项目在从算术到微分方程的各种课程中采用了GNA方法，从而使课程和教学发生了变化。学生成绩的相应改革包括解决问题和批判性思维能力的提高，概念的获得，动机和建立联系。这个项目为高中和大学提供了一种实践的、积极的数学学习体验模式。

This project is integrating graphical, numerical, and analytical (GNA) approaches in all levels of the mathematics program at Adirondack Community College through the use of classroom sets of handheld palm-top computers with DERIVE and graphing calculators. Pilot programs at Adirondack have shown that it is possible to transform the traditional mathematics classroom into an active laboratory environment with cooperative groups of students exploring concepts and real world problems. The project is producing curricular and instructional changes resulting from the GNA approaches in a wide variety of courses ranging from arithmetic through differential equations. Corresponding reforms in student outcomes include an improvement in problem solving and critical thinking skills, concept attainment, motivation, and making connections. This project is serving as a model of a hands-on, active mathematics learning experience for both high schools and universities.
