CAS Intensive Mathematics

9618029海德宾夕法尼亚州立大学正在开发，实地测试和修改模块化中学数学课程，供经常使用计算器或计算机技术的学生使用，包括连接的计算机代数系统（CAS）和动态几何工具；基于计算器的数据收集工具；以及电子数据库。这些材料以内容链的形式开发，预计将花费六到九周的课堂时间；这些部分可以按顺序放在一起形成一个为期一年的课程，其中一些部分将被开发成独立的单元，与一些新兴的国家科学基金会资助的综合课程结合使用。相当重视准备试点和实地测试教师来处理这些材料，并利用这些经验来编写材料，以帮助其他教师使用这些教学材料。目前正在进行一项全面的研究，其中包括对教学材料的评价和对学生对所研究的数学主题的理解水平的研究。

9618029 Heid Pennsylvania State University is developing, field testing, and revising a modular secondary school mathematics curriculum for use by students who have regular access to: calculator or computer technology that includes a linked computer algebra system (CAS) and dynamic geometry tool; calculator-based data-gathering tools; and electronic data bases. The materials are developed in strands of content that are expected to consume six-to-nine weeks of class time; the strands could be put together sequentially to form a year-long course and several strands would be developed as stand-alone units usable in conjunction with some of the emerging NSF-funded, comprehensive curricula. Considerable attention is paid to preparing the pilot- and field-test teachers to handle the material and these experiences are used to develop materials to help other teachers use the instructional materials. A comprehensive study is being made that will include an evaluation of the instructional materials and research into the level of students' understanding of the mathematics topics studied.
