工程图学教师的PCK结构及其建构

Study on Teachers'Knowledge Structure and Construction of Engineering Graphics Teachers in the Fields of PCK

PCK是教师教学最有效的知识,工程图学教师的PCK主要包括:基于对图形认识的工程图学学科知识、工程图学课程的学生知识、工程图学的课程知识、工程图学特定课题的教学策略及表征知识。PCK是教师在教学实践中不断建构和动态发展的,工程图学教师PCK建构的基本策略有:培养教师的教学思维方式、提高教师对学科的理解水平、发展教师的工程图学课程知识、关注学生对工程图学的理解程度、丰富教师的PCK教学资源。

PCK is the most effective knowledge for teachers to teach.Engineering graphics teachers'PCK mainly includes the knowledge of engineering graphics subject based on the understanding of graphics,the knowledge about students'understanding of engineering graphics course,the knowledge of engineering graphics curriculum,and the knowledge about the teaching strategies and representation of specific topic.Teachers'PCK is the continuous construction and dynamic development based on practice.The basic strategies of PCK construction for engineering graphics teachers are proposed:forming teaching thinking mode that can help teachers develop their PCK;promoting teachers'understanding of subjects;developing teachers'knowledge of Engineering graphics;focusing on students'understanding of Engineering graphics;enriching teachers'PCK teaching resources.
