【摘要】 本研究基于定量的研究方式测查189名化学职前教师PCK的结构与水平,结果表明(1)化学职前教师的PCK结构主要包括KoC、KoL、KoS、KoA等4个组分,且该结构具有良好的信度与效度;(2)化学职前教师PCK的4个组分之间存在显著相关,且显性的PCK教学方式比隐性的更有利于职前教师对PCK组分间的整合;(3)化学职前教师的PCK水平除KoS组分水平较为理想,其他知识组分水平均处于中等或中下水平;(4)在不同的PCK教学方式(显性或隐性)下,化学职前教师的PCK水平存在显著性差异。更多还原

【Abstract】 This study investigated the structure and level of 189 preservice chemistry teachers’ based on quantitative research methods. Results indicated that(1) the structure of preservice chemistry teachers’ s PCK mainly included four components, such as KoC, KoL, KoA, KoS and had good reliability and validity;(2) there was significant correlation among the four components of PCK, and the explicit PCK teaching method was more favorable to the integration of the components than the implicit ones;(3) the level of KoS was relatively ideal, while the other three components are at medium or lower level;(4) there was a significant difference in the level of PCK under different teaching method(explicit or implicit) of PCK.更多还原
