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

该SGER项目将为华盛顿州中学科学教师和学生建立课堂评估工具奠定基础。研究人员将为6至10年级的学生确定对物理科学概念、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，并在全州的几个学区进行研究，将确定学生思维的大约200个方面。Minstrell的思维层面框架可以用来编写问题，以诊断特定的问题理解，并设计针对这些理解的指导。面观对30多名高中物理教师产生了重大影响。该项目将开始扩大这一视角，每年为约2000名科学教师和40多万名中学生提供服务。这个项目的结果将在2000年秋季被华盛顿州用于修订华盛顿州科学评估的官方版本，该版本已被立法用于8年级和10年级。该项目还将为下一轮项目提供信息，这些项目将创建用于评估和教学的课堂、诊断工具，以促进更好的学习。（请参阅http://www.talariainc.com和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.
