设计开发测评工具 探查教师概念水平——以美国ATLAST项目为例

Design and Develop the Evaluation Tools to Assess Teachers' Understanding of Concepts——For American Assessing Teacher Learning about Science Teaching Program As an Example

学科内容知识是学科教学知识中最为重要的知识,对教师的专业发展有至关重要的影响。美国科学教师的教学评价研究项目基于学习科学的最新理论,以核心概念为主轴,以错误概念为探针,采用情境化题组的形式呈现问题情境,建立起测试目标、测试内容和测试情境三者之间的有意义联系,基于错误概念及情景化题组的研发理念贯穿始终,从而开发出一套个性鲜明的测评教师学科内容知识的工具。该工具的理论基础、开发过程、设计思路及其富有情景化的表述,都能够对我国教师专业发展测评工具的开发提供一定启示。

Content knowledge is the most important knowledge of pedagogical content knowledge （PCK）, and it has a crucial impact on the professional development of teachers. Assessing Teacher Learning about Science Teaching Program （ATLAS） is based on the lat- est theories of learning science, threaded by core concepts, misconceptions as probe, and using contextual test groups to present the test questions. Thus, a meaningful connection among aims, content and test context is built up, and ATLAS developed a set of evaluation tools for teachers＇ content knowledge. The paper focus on theoretical foundation, develop- ment progress, design ideas and rich contextual representations of the tools. These ideas are worthy of attention for the design of teachers＇ content knowledge evaluation tools.
