Videotaped Classes in Mathematics and Science - Project VTC

职训局计划的目标是介绍和探讨在数学和科学教师教育中使用教学“案例”。这些案例是现实情况，提出了理论和实践关切的背景问题以供讨论和分析。教学案例开始用于教师教育，教授问题解决和课堂管理等一般方面，但这种方法在包括数学和科学在内的学科领域很少尝试。VTC项目将制作约一小时的录像带，代表几个中级量化科学中具有教学意义的案例。这些案例将把学龄儿童的数学理解和表达问题与他们不断发展的基本科学概念意识结合起来。职训局计划亦会制作一本简短的手册，以配合录影个案。本手册将简要介绍教学案例的一般用法，并就如何使用磁带上的案例提出建议。该项目将向数学和科学教育工作者以及在师范教育中使用案例研究的研究人员传播这些材料。

The goal of Project VTC is to introduce and explore the use of pedagogical "cases" in teacher education in mathematics and science. These cases are realistic scenarios which raise contextualized issues of theoretical and practical concern for discussion and analysis. Pedagogical cases are beginning to be used in teacher education to teach such generic aspects as problem solving and classroom management, but this approach has rarely been tried in the subject matter areas, including mathematics and science. Project VTC will produce approximately one hour of videotape representing several pedagogically interesting cases in secondary-level quantitative science. These cases will integrate issues of school children's mathematical understanding and expression with their developing sense of fundamental scientific concepts. Project VTC will also produce a short manual to accompany the videotaped cases. This manual will provide a brief introduction to the use of pedagogical cases in general, as well as suggestions for using the cases presented on the tape. The Project will disseminate these materials to mathematics and science educators and to researchers in the use of case studies in teacher education.
