化学师范生PCK中“学生知识”调查及培养策略研究

Investigation and training strategy of “student knowledge” in PCK of chemistry majors from normal universities

"学生知识"是教师学科教学知识(PCK)的重要组成维度之一,对其进行研究具有较大的意义。通过问卷调查法及访谈法对化学师范生PCK中"学生知识"的来源及"学生知识"对教学设计的影响进行研究。结果表明:在"学生知识"来源方面,相对于化学教育类课程,教育学和心理学课程对师范生的影响较大;在"学生知识"来源方面,教育实习过程中"课堂教学实践"对化学师范生的影响较大;化学师范生进行教学设计时,考虑最多的因素是"学生知识",考虑最少的因素是"课程标准"。根据研究结果,提出了优化和培养化学师范生PCK中"学生知识"的有效策略。

The “student knowledge” is an important component of teachers’ pedagogical content knowledge (PCK),so it is greatly significant to research it.The sources of “student knowledge” in PCK of chemistry majors from normal universities and its influence on teaching design are researched through questionnaires and interviews.It is discovered that pedagogy and psychology curriculum in college have a greater impact on the source of “student knowledge”,compared with chemistry education curriculum.In terms of the source of “student knowledge”,classroom teaching practice has a great influence on the chemistry majors from normal universities in the process of teaching practice.In the teaching design for the chemistry majors from normal universities,the most important factor is "student knowledge",while the least important factor is "curriculum standard".Moreover,some effective strategies are proposed to optimize and develop “student knowledge”.
