A Study of "Seeing and Thinking Mathematically" Units with Linguistically- and Culturally-Diverse Students

小行星9453671 该项目关注美国教育中的两个当前问题： 数学教育的改革由NCTM标准和需要服务于语言和文化多样性（LCD）的学生群体。 由美国教育发展中心（EDC）根据美国国家科学基金会（NSF）授予的ESI-9054677号奖开发的数字单元表的实施情况，在加州州系统倡议的加州中学数学复兴所服务的学校进行评估。 本单元为六年级设计，包括数字表征系统，数字的多重表征和数字表征设备的材料。 此外，它侧重于调查，发明，符号化和数学交流。 评估包括课堂观察，与教师，学生，管理人员和家长的个人和焦点小组访谈以及学生工作的审查。 结果是一般原则的设计和实施的教学材料，液晶显示器的学生和教师实施类似的教学材料的指导。

9453671 Kleiman This project focuses on two current issues in American education: reform in mathematics education led by the NCTM Standards and the need to serve a linguistically and culturally diverse (LCD) student population. The implementation of the unit Languate of Numbers developed by EDC under NSF award number ESI-9054677 is evaluated in schools served by the California Middle School Mathematics Renaissance of the California State Systemic Initiative. This unit, designed for sixth grade, includes material on number representational systems, multiple representations of numbers, and number representational devices. In addition, it focuses on investigation, invention, symbolization, and communicating mathematically. The evaluation consists of classroom observations, individual and focus group interviews with teachers, students, administrators and parents as well as review of student work. The outcome is general principles for the design and implementation of instructional materials for LCD students and guidance for teachers implementing similar instructional materials.
