CAS Intensive Mathematics

小行星9618029 宾夕法尼亚州立大学正在开发、实地测试和修订一个模块化的中学数学课程，供经常接触以下内容的学生使用：计算器或计算机技术，包括一个链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。 这些材料是在内容链中开发的，预计将消耗六到九周的课堂时间;这些链可以按顺序组合在一起，形成一个为期一年的课程，并将开发几个链作为独立的单元，可与一些新兴的NSF资助的综合课程结合使用。相当重视培养试点和实地测试教师处理教材的能力，并利用这些经验编写教材，帮助其他教师使用教材。 目前正在进行一项综合研究，其中包括对教材的评价和对学生对所研究的数学主题的理解程度的研究。

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.
