A Model Teacher Enhancement Project to Improve Mathematics Teaching and Learning in Grades 4-8 Utilizing Calculators

这个为期两年的项目由MDRI和DTPE共同资助，将为4-6年级的学生开发基于计算器的数学教学材料，并帮助教师在课堂上使用这些材料。这些材料将强调学生解决问题的能力的发展，并将促进过渡到代数。总共将编制50至75个课程，并附有教师手册。在项目的第一年，来自芝加哥大都会地区三所学校的六名教师将在他们自己的教室里试用这些材料。在第二年，修订后的教材将由来自10所学校的20名教师进行实地测试，他们将同时参加关于教材内容和使用的学年课程。评估将衡量项目对学生数学学习和态度的影响。伊利诺伊大学芝加哥分校的费用分摊额相当于国家科学基金会奖金的67%。

Jointly funded by MDRI and DTPE, this two-year project will develop calculator-based instructional materials in mathematics for students in grades 4-6 and will prepare teachers to use those materials in their classrooms. These materials will stress the development of students' problem-solving skills and will facilitate the transition to algebra. A total of 50 to 75 lessons will be developed, along with accompanying teachers' manuals. During the first year of the project, a total of six teachers from three schools in the Chicago metropolitan area will pilot test the materials in their own classrooms. During the second year, the revised materials will be field tested by a total of 20 teachers from 10 schools, who will simultaneously participate in an academic-year course on their content and use. The evaluation will measure the project's effect on student learning of and attitudes towards mathematics. The University of Illinois at Chicago is contributing as cost-sharing an amount equal to 67% of the NSF award.
