Project AIM: All Included in Mathematics

北卡罗来纳州立大学和地平线研究公司的开发人员和研究人员正在调整和研究语言艺术教学中使用的成功话语策略，以帮助教师促进数学丰富的课堂话语。该项目特别感兴趣的是使用模型来促进数学交流，包括英语学习者（ELL）在数学话语中的交流。该项目被认为是一个设计实验，包括连续的教学工程周期，研发团队设计专业学习任务，与教师一起实施任务，并修改任务及其顺序，以更好地支持期望的学习成果。然后，项目团队的成员检查PD对教师教学的影响，以及在PD辅助设备、年级水平和课程材料之间扩大材料的可能性。本项目提出的指导研究和开发工作的首要研究问题是：多面手小学教师如何学会促进高质量的数学话语，使课堂上的所有学生都能参与其中，并使这些学生参与有意义的数学学习机会？我们如何扩大旨在支持小学教师学习如何在课堂上促进高质量数学话语的干预措施？该项目将形成一个完整的40小时的专业发展模块，以支持二年级教师的数学教学，重点是位值、多位数加减法和线性测量。该计划的主要专业学习任务将在数学教练和教师的一系列会议中进行试点和研究。

Developers and researchers at North Carolina State University and Horizon Research, Inc. are adapting and studying successful discourse strategies used during language arts instruction to help teachers promote mathematically-rich classroom discourse. Of special interest to the project is the use of models to promote mathematics communication that includes English language learners (ELL) in mathematics discourse. The project is conceived as a design experiment that includes successive instructional engineering cycles in which the R&D team designs professional learning tasks, implements the tasks with teachers, and revises the tasks and their sequencing to better support the desired learning outcomes. The members of the project team then examine the effects of the PD on teachers' instruction and the possibilities for scaling up the materials across PD facilitators, grade levels, and curriculum materials. The overarching research questions guiding the research and development effort proposed in this project are: How do generalist elementary teachers learn to promote high quality mathematics discourse that includes all students in their classrooms and engages those students in meaningful mathematics learning opportunities? How do we scale up an intervention designed to support elementary teacher learning of ways to promote high quality mathematics discourse in their classrooms?The project will result in a full 40-hour professional development module to support mathematics discourse for Grade 2 teachers, with an emphasis on place value, multidigit addition and subtraction, and linear measurement. The main professional learning tasks of the program will have been piloted and studied in a series of sessions with mathematics coaches and teachers.
