摘　　要：本研究设计《化学PCK量表式问卷》测查204名化学职前教师在LBCD课程模式干预前后PCK组分水平的变化,并检验问卷的信效度和Magnusson等人提出的PCK五组分模型的合理性。研究结果表明:(1)问卷具有良好的信效度;(2)PCK五组分模型具有一定的合理性;(3)LBCD课程模式对化学职前教师PCK组分发展有统计学意义上的显著促进效果,且各组分的发展呈现出不均衡性。文末据此对化学PCK测评和组分界定,以及化学教师教育提出将LBCD课程模式应用在不同教师群体、参考本研究的方法定量检验其他学者提出的PCK组分模型等建议。This study designed the chemistry PCK questionnaire to test the development of PCK component level of 204 chemistry preservice teachers before and after the intervention of LBCD curriculum mode,as well as to test the reliability and validity of the questionnaire and the rationality of the PCK five component model proposed by Magnusson et al.The results show that:(1)The questionnaire has good reliability and validity;(2)The PCK five component mode has rationality;(3)LBCD curriculum mode has a statistically significant effect on the development of PCK components of chemistry preservice teachers,while the development of each component is uneven.Finally,some suggestions are put forward for the measure and component definition of PCK,as well as for chemistry teacher education,such as applying the LBCD curriculum mode to different groups of teachers,and quantitatively testing the PCK component model proposed by other scholars with reference to the method of this study.
