Teaching Teachers: Developing Faculty Expertise in Supporting Preservice Elementary Teachers' Development of Mathematics Knowledge for Teaching

该项目旨在：为负责教授职前小学教师(PST)的数学教师开发专业发展讲习班使用的录像带和其他教学材料的集合；评估这些材料对教师参与者及其学生的影响；使为PSTS教授内容课程的数学教师能够发展专门知识，支持PSTS发展教学所需的数学知识；阐明数学教师教育工作者支持PSTS发展教学所需数学知识的性质。学前数学课程往往不能为教学工作做好充分的准备。这些课程往往侧重于内容的学习，对如何在教学实践中使用这些知识的关注很少，而在将PST知识应用于分析解决策略或评价数学解释方面提供的经验相对较少。此外，教授内容的数学教师需要了解如何为PST创造机会，让他们以教学所需的方式学习数学，这是一种他们往往不熟悉的教与学的观点。

This project aims to: develop a collection of videocases and other teaching and learning materials to be used in professional development workshops for mathematics faculty who are responsible for teaching preservice elementary teachers (PSTs); evaluate the impact of these materials on both faculty participants and their students; enable mathematics faculty, who teach content courses for PSTs, to develop expertise in supporting PSTs' development of mathematics knowledge needed for teaching; and articulate the nature of specialized content knowledge mathematics teacher educators need to support PSTs' development of mathematics knowledge required for teaching. Preservice mathematics coursework often fails to adequately prepare PSTs for the work of teaching. The coursework frequently focuses on the learning of content giving limited attention to how such knowledge is used in teaching practice, while providing relatively few experiences in applying PSTs' knowledge to analyze solution strategies or appraise mathematical explanations. In addition, mathematics faculty who teach content need to understand how to create opportunities for PSTs to learn mathematics in ways needed for teaching, a view of teaching and learning with which they are often unfamiliar.
