信息技术支持下的学科教学知识的结构特征解析与案例研发路径

On the Structural Characteristics of Technology-Supported Pedagogical Content Knowledge and the Approach of Its Case Study

技术支持下的学科教学知识是学科教学知识在信息化时代的发展,是新出现的一种知识类型,是来源于对技术,内容和教法知识互动的一种理解,超越了内容、技术和教法这3种基本成份,是教师用技术进行有效教学的知识基础.该框架的提出开辟了从教师教学知识的视角探讨信息技术与课程整合的新思路.按选择、对比分析、检验、修正的流程开发TPCK案例,是信息化背景下促进教师专业发展的一条可行路径.

Technology-supported pedagogical content knowledge（TPCK） is the development of pedagogical content knowledge in the information age and is crucial to the effective teaching.As a new type of knowledge,it comprises knowledge of content,pedagogy and technology,as well as the complex interaction between these knowledge components.This concept provides a new route for the integration of information technology from the angle of teacher knowledge.To design TPCK cases is to abide by the process of the selection,comparative analysis,inspection and revision,which is a viable way for the professional development of teachers under the background of informationization.
