Empowering Mathematics Teachers in Computer-Intensive Environments

宾夕法尼亚州立大学将开展一个为期三年的项目，以增强300名处于计算机密集型环境中的初中和高中数学教师的能力，并为实施计算机密集型课程，特别是计算机密集型代数课程做好教师准备。该项目将通过四个部分让参与者参与：计算机密集型数学课程、理解学生理解的数学教育课程、教师作为研究人员参与的实践以及在计算机密集型环境中解决数学教与学问题的课堂实施。这些部分将通过为期四周的暑期强化课程、学年期间的后续活动、为一部分实施计算机强化代数的教师进行为期一年的实习以及在实施的第一年向所有教师提供支助来完成。此外，这一教师提升模式将研究教师实施的任务型访谈和计算机主动测试对他们理解学生理解的影响。参与者将在全国范围内招募，目标地区为华盛顿特区、芝加哥和旧金山。参与者可以选择获得8个研究生学分。除第一批参加者外，另有900名第二批参加者将担任密集使用电脑的推动者，使教师总人数增至1200人。在计算机密集的环境中工作，参与者将学习到新的教学角色--这些角色将不再强调常规技能的训练，而强调以计算机为基础的数学概念探索。他们将开发新的策略来评估学生的学习和分配分数。宾夕法尼亚州州立大学和参与学校的费用分摊占NSF预算的8%。

The Pennsylvania State University will conduct a three-year project to empower 300 middle and high school mathematics teachers in computer-intensive environments and to prepare teachers for implementing computer intensive curricula in general and computer-intensive algebra in particular. The project will engage participants through four components: a computer-intensive mathematics course, a mathematics education course in understanding student understanding, a practicum involving teaches as researchers, and classroom implementation addressing issues in the teaching and learning of mathematics in computer-intensive environments. These components will be accomplished through four-week intensive summer courses, follow-up activities during the school year, a year-long practicum for a subset of the teachers implementing computer- intensive algebra, and support for all teachers during their first year of implementation. In addition, this teacher enhancement model will study the effects of teacher- implemented, task-based interviews and computer-active testing on their understanding of student understanding. Participants will be recruited nationwide, with targeted areas of Washington, DC, Chicago and San Francisco. Participants may elect to receive eight graduate credits. In addition to the first-wave participants, an additional 900 second-wave participants will be effected through enactment of roles as computer-intensive facilitators, bringing the total numbers of teachers enhanced to 1200. In working in a computer-intensive environment, participants will learn new teaching roles -- roles that will deemphasize training in routine skills and emphasize computer-based exploration of mathematical concepts. They will develop new strategies for assessing student learning and for assigning grades. Pennsylvania State and participating schools' cost- sharing accounts for 8% of the NSF budget.
