Using Computer Technology and Multimedia Materials to Develop an Integrated Systems Approach to the Earth Sciences

将开发一系列计算机模块，以传统教学方法无法实现的方式模拟地球系统中活跃的物理、化学和生物过程。这些计算机模型不仅可以补充课堂教学，还可以帮助学生可视化地质时间、三维结构和从“微米到山脉”尺度上的地质现象的动态过程。这个多媒体计画的目标是要开发出以下的课程材料：1)聚焦于地球系统中运作的物理、化学和生物过程；2)结合多种学习方法（动手活动、视觉辅助、三维模型和系统模拟）；3)包含相关且综合的问题解决方案。这些材料将成为综合课程包的一部分，其中计算机模块将加强学习过程。这个项目是由美国地球物理联合会赞助的合作项目，在亚利桑那大学、格伦代尔社区学院和其他机构对这些材料进行了实地测试。每年将有2000名人文教育专业的学生受到影响。该项目的主要重点是开发新的教学材料，为未来的教师提供坚实的知识基础以及对科学探究行为的欣赏。将编制计算机练习光盘、实验室手册和教员手册，供全国分发。

A series of computer modules will be developed to simulate the physical, chemical, and biological processes active in Earth systems in ways not possible with traditional instructional methods. These computer models not only will supplement classroom instruction, they will help students visualize dynamic processes that occur over geologic time, three dimensional structures, and geologic phenomena on scales ranging from "microns to mountains". The goals of this multi-media project are to develop curriculum materials that: 1) focus on the physical, chemical, and biological processes at work in Earth systems, 2) incorporate multiple learning approaches (hands-on activities, visual aids, three dimensional models, and simulations of systems), and 3) contain relevant and integrative problem solving . These materials will be part of an integrated curriculum package in which the computer modules will enhance the learning process. This project is a collaborative effort sponsored by the American Geophysical Union, with field testing of the materials at the University of Arizona, Glendale Community College, and other institutional settings. The project will affect 2000 liberal arts and education majors per year at these institutions. A primary focus of this project will be the development of new instructional materials that will provide future teachers with a solid knowledge base as well as an appreciation for the conduct of scientific inquiry. A CD-ROM of the computer exercises, laboratory manual, and instructor's manual will be developed for national dissemination.
