Empowering Teachers: Mathematical Inquiry Through Technology

BBN系统和技术公司将实施一项为期三年半的计划，以开发和评估一项全面的教师提升计划，以促进中学数学课堂中数学探究教学的策略、艺术和实践。该计划使用交互式计算机软件和视频技术作为培养探究性学习和教学技能的关键教学工具。该计划将包括四门研究生水平的课程，其中两门，关于数据的推理和数学探索与实验，是在最近完成的教师提升拨款中开发的。这两门新课程是动画几何和交互代数，将广泛利用计算机活动来支持探究式教学。这些课程将在波士顿的马萨诸塞大学、剑桥的莱斯利学院和教育合作研究所进行实地测试。将认真记录教师因这些课程而改变的程度。这些课程将得到马萨诸塞州教育部的认可，并由马萨诸塞州教育电信公司在全州范围内传播。将通过NCTM或AERA等相关组织会议的会前讲习班，在全国范围内进行宣传。240多名中学教师将参与这些课程的开发和试点。LOGO计算机系统、关键课程出版社、EDCO、MCET和BBN费用分摊占NSF预算的7%。开发创造性地利用最新技术的教师培训材料确实是可取的。BBN生产的产品处于技术的尖端。马萨诸塞州教育电信公司为传播如此开发的课程材料提供了极好的途径。

BBN Systems and Technologies will conduct a three-and-one- half-year program to develop and assess a comprehensive teacher enhancement program to foster the strategies, art, and practice of mathematical inquiry teaching in middle school mathematics classrooms. The program employs interactive computer software and video technology as key instructional tools for fostering inquiry learning and teaching skills. The program will comprise four graduate- level courses, two of which, Reasoning About Data and Mathematical Exploration and Experiment, were developed in a recently completed teacher enhancement grant. The two new courses, Animated Geometry and Interactive Algebra, will draw extensively on computer activities for supporting inquiry teaching. The courses will be field-tested at the University of Massachusetts, Boston; Lesley College, Cambridge; and the Educational Collaborative. Careful documentation of the extent to which teachers change as a result of these courses will be undertaken. The courses will be endorsed by the Massachusetts Department of Education and disseminated statewide by the Massachusetts Corporation for Educational Telecommunications. National dissemination will be instantiated through pre-conference workshops of relevant organizational meetings such as NCTM or AERA. Over 240 middle school teachers will be involved in the development and piloting of these courses. Logo Computer Systems, Key Curriculum Press, EDCO, MCET and BBN cost-sharing accounts for 7% of the NSF budget. Developing teacher enhancement materials which creatively make use of the latest technology is indeed desirable. BBN produces products that are at the cutting edge of technology. And the Massachusetts Corporation for Educational Telecommunications provides and excellent avenue for dissemination of the course materials so developed.
