COMET: Cases of Mathematics Instruction to Enhance Teaching

9731428银 COMET项目致力于创建和传播中学数学专业发展材料。这个项目由爱德华银博士指导，位于匹兹堡大学，与宾夕法尼亚州立大学的玛格丽特·史密斯博士合作，涉及16个案例的发展，每个案例都涉及一堂课堂课，其中中学数学（6-8年级）中的一个重要思想与一项具有认知挑战性的任务相联系。 这些案例将分为四组，每组大约有四个案例，每个案例都与一个重要的数学主题有关。 暂定类别包括：解决二维和三维的测量问题;解决与代数有关的问题，作为模式和函数的研究;解决涉及比率，比率和比例的推理问题;解决涉及数字和图形形式的统计数据的表示和分析的问题。项目案例将涉及使用QUASAR项目产生的材料和经验。 此外，该项目将涉及NSF资助的实施中心（密苏里州和EDC网站的大学）和NSF资助的课程项目（连接数学，数学在上下文中，和视觉数学）作为现场的情况下实施。 本课题的独特之处在于运用案例的方法，立足于实际实践，有较强的研究基础，并涉及到中学数学课程。 COMET将在项目的第一年组织和主办一次小型会议（将在NSF举行），讨论案例及其在提高教师内容和专业知识方面的应用。 此外，该项目的评价将包括对COMET案例对项目实地测试参与者（中学教师）的内容和专业知识产生影响的程度进行形成性评价。

9731428 Silver The COMET Project is dedicated to the creation and dissemination of professional development materials in middle school mathematics. This project, directed by Dr. Edward Silver and located at the University of Pittsburgh, with a subcontract with Dr. Margaret Smith at The Pennsylvania State University, involves the development of sixteen cases, each involving a classroom lesson in which an important idea in middle school mathematics (grades 6-8) is linked with a cognitively challenging task. The cases will be developed in four clusters; with about four cases in each cluster, each related to an important mathematics topic. Tentative clusters include: solving measurement problems in two and three dimensions; solving problems related to algebra as the study of patterns and functions; solving problems involving reasoning with rates, ratios, and proportions; and solving problems involving the representation and analysis of statistical data in numerical and graphical forms. The project cases will involve the use of materials and experiences generated by the QUASAR Project. In addition, the project will involve NSF-funded implementation centers (the University of Missouri and EDC sites) and NSF-funded curriculum projects (Connected Mathematics, Mathematics in Context, and Visual Mathematics) as field sites for the implementation of the cases. The uniqueness of this project is in the use of cases based on actual practice and a strong research base and dealing with the middle school mathematics curriculum. COMET will organize and host a small conference (to be held at NSF) on cases and their use in the enhancement of teacher content and professional knowledge in the first year of the project. Additionally, the project's evaluation will include a formative evaluation of the extent to which the COMET cases have impacted the content and professional knowledge of the project's field test participants (middle school teachers).
