Building a Facet-Based Diagnostic Assessment System for Promoting Learning in Classrooms

这个SGER项目将为华盛顿州的中学科学教师和学生建立课堂评估工具奠定基础。 调查人员将确定6至10年级学生对物理科学概念、过程和科学本质的特殊理解。 通过回顾现有的关于学生概念的研究和在全州几个学区进行研究，将确定大约200个方面的学生思维。明斯特雷尔的思考框架的方面可以用来写问题诊断具体的问题的理解和设计教学目标，这些理解。 面向的观点已经为大约30名高中物理教师带来了实质性的和显著的变化。本项目将开始扩大这一观点，为大约2000名科学教师服务，并增加到400名。2000年秋季，该项目的结果将被该州用于修订华盛顿州科学评估的官方版本，该评估已被立法用于评分8和10。 该项目还将为下一轮项目提供信息，这些项目将创建课堂、评估和教学诊断工具，为更好的学习服务。（请参阅http：www.talariainc.com及http：weber.u.washington.edu/~huntlab/diagnoser/facetcode.html）

This SGER project will lay the groundwork for building classroomassessment tools for secondary science teachers and students in the Stateof Washington. The investigators will identify the particularunderstandings of physical science concepts, processes, and nature ofscience for students in grades 6 through 10. Approximately 200 facets ofstudents thinking will be identified by reviewing existing research onstudents conceptions and by conducting research in several schooldistricts across the state. Minstrell's Facets of Thinking framework canbe used to write questions for diagnosing specific problematicunderstandings and for designing instruction that targets theseunderstandings. The facets perspective has made substantial andsignificant changes for about thirty high school teachers of physics.This project is to begin scaling-up that perspective to serve about 2000science teachers and upwards to 400,000 secondary students each year.Results of the project will be used during fall of 2000 by the state torevise the official version of Washington State Science Assessments whichhas been legislated for grades 8 and 10. The project will also inform anext round of projects that will create classroom, diagnostic tools forassessment and teaching in the service of better learning.
