回归PCK概念的本原:职前化学教师PCK观念研究

Returning to the Original Ideas of PCK: Study of Pre-Service ChemistryTeachers’ Conceptions of PCK

PCK是教师教育领域内的重要概念。本研究在不预设理论框架的前提下,从Shulman提出的PCK原始概念出发,设计访谈问题,调查职前化学教师的PCK观念,通过扎根理论质性编码,尝试构建我国职前化学教师的PCK模型。研究发现,职前化学教师的PCK包括10个组分,分为主题专属PCK和一般性PCK。我国职前化学教师的PCK模型与国际上传统PCK模型既有一致性又有差异性;职前化学教师最关注的组分是教学策略知识和学生特点,对评价知识、资源知识、教师情感等组分较少提及。

PCK is an important concept in the field of teacher education.Based on the original ideas of PCK proposed by Shulman,this study designed interview protocols,investigated the pre-service chemistry teachers’conceptions of PCK,and tried to build a PCK model of pre-service chemistry teachers in China by taking grounded theory coding.The study found that the PCK of pre-service chemistry teachers included 10 components,which were divided into the topic-specific PCK and the general PCK.There were some similarities as well as differences between the PCK model of pre-service chemistry teachers in China and the international PCK models.In addition,pre-service chemistry teachers paid most attention to knowledge of instructional strategies and students’characteristics,but seldom mentioned knowledge of assessment,knowledge of resources and teachers’affect.
