A New Method of Assessing and Changing Students' Understanding of Mathematical Problem-Solving

这个项目是开发和测试20-24录像带场景 基于现实的解决问题的情况。 录像带是为了 可用于两种方式：（1）作为评估工具，以衡量学生的 解决问题的技能和信念，（2）作为指导 促进解决问题的设备。 材料的重点 将是学生对问题的信念和解决方法 他们 录像带的场景将显示儿童参与一个 共同努力解决现实生活中的问题。 录像带会 用于发展4-6年级儿童的能力， 认识到问题的情况，从这些发展问题， 情况，然后解决问题。 同时可能 将是用来评估学生 对问题解决的理解和处理。 所有材料，包括用户指南，都将编入 NCTM标准。

This project is to develop and test 20-24 videotape scenarios based on realistic problem-solving situations. The tapes are to be used in two ways: (1) as assessment tools to measure students' problem-solving skills and beliefs, and (2) as instructional devices to promote problem solving. The focus of the materials will be on students' beliefs about problems and ways to solve them. The videotape scenarios will show children involved in a cooperative effort to solve real-life problems. The tapes will be used to develop the abilities of children in grades 4-6 to recognize problem situations, to develop problems from these situations, and then solve the problems. Simultaneously, there will be instruments developed to assess the students' understanding and dispositions about problem solving. All material, including a user's guide, will be indexed to the NCTM standards.
