Implementing the Mathematical Practice Standards: Enhancing Teachers' Ability to Support the Common Core State Standards

实施数学实践标准（IMPS）是一个为期四年的项目，旨在编写教材，帮助教师了解如何在数学教学中实施《国家共同核心数学标准》中描述的数学实践。改进教学的目的是帮助学生接受并重视这些重要的数学练习。教育发展中心的研究人员正在制作示范数学练习的视频和印刷材料，并与5-10年级的教师合作，帮助他们有效地使用这些材料。本项目的研究问题集中在材料的哪些特征对教师最有帮助，哪些专业发展特征有助于在课堂教学中实施数学实践。该项目的外部评估由TERC的评估人员进行，他们正在研究开发材料的过程以及材料的使用方式。这些材料将包括专业制作的视频，举例说明在课堂上实施的特定数学练习，以及旨在帮助教师理解练习以及为什么学生获得数学练习至关重要的印刷对话。根据试点工作和5-10年级数学家、数学教育者和数学教师的系统建议，正在制定数学实践范例。设计过程是迭代的，材料是根据收到的反馈进行改进的。辅导员正在准备进行专业发展，各学区的150多名教师正在对教材进行测试。NCTM和NCSM等专业团体呼吁提供CCSS数学实践的例证材料。他们认为，教师需要了解如何在课堂上实现这些标准。IMPS系统地努力设计符合标准的材料，不仅测试材料，而且测试与材料相关的专业发展，这是对国家需求的回应。录像和对话将通过广泛传播提供。

The Implementing Mathematical Practices Standards (IMPS) is a four-year project that is producing materials designed to help teachers see how the mathematical practices described in the Common Core State Standards for mathematics can be implemented in mathematics instruction. The goal of the improved instruction is to help students adopt and value these critical mathematical practices. Researchers at the Education Development Center are developing videos and print materials that exemplify the mathematical practices and are working with teachers in grades 5-10 to help them use the materials effectively. The research questions of the project are focused on what features of the materials are most helpful to teachers and what professional development characteristics facilitate implementation of the mathematics practices in classroom instruction. The external evaluation of the project is being conducted by evaluators at TERC who are looking the process of developing materials and how the materials are used. The materials will include professionally-produced videos exemplifying a particular mathematical practice being implemented in a classroom as well as printed dialogues that are designed to help teachers understand the practice and why it is critical for students to acquire that mathematical practice. The exemplars of mathematical practices are being developed based on pilot work and systematic advice from mathematicians, mathematics educators and mathematics teachers in grades 5-10. The design process is iterative and materials are refined based on feedback that is received. Facilitators are being prepared to conduct professional development and materials are being tested by more than 150 teachers in a variety of school districts. Professional groups such as NCTM and NCSM have called for materials that exemplify the CCSS mathematical practices. They have argued that teachers need to understand how these standards can be achieved in classrooms. IMPS systematic effort to design materials that exemplify the standards and to test not only the materials but also the professional development associated with the materials is responding to the national need. The videos and dialogues will be available through broad dissemination.
