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，使300名初中和高中数学教师在计算机密集的环境中获得能力，并使教师为实施计算机密集课程做好准备，特别是计算机密集的代数课程。该项目将通过四个部分吸引参与者：计算机密集型数学课程，理解学生理解能力的数学教育课程，教师作为研究人员参与的实习，以及解决计算机密集型环境中数学教学问题的课堂实施。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、为实施计算机密集代数的部分教师提供为期一年的实习，以及在实施第一年为所有教师提供支持来完成。此外，该教师增强模型将研究教师实施、任务型访谈和计算机主动测试对教师理解学生理解的影响。参与者将在全国范围内招募，目标地区包括华盛顿特区、芝加哥和旧金山。参与者可以选择获得8个研究生学分。除了第一阶段的参与者外，第二阶段的900名参与者将通过扮演电脑集约化促进者的角色而受到影响，使教师总数增加到1200人。在计算机密集的环境中工作，参与者将学习新的教学角色，这些角色将不再强调常规技能的培训，而是强调基于计算机的数学概念探索。他们将制定评估学生学习和评分的新策略。宾夕法尼亚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.
