微课的设计与制作对教师学科教学知识发展的研究——以外研社第三届“教学之星”全国总决赛为例

A study of how the process of designing micro-lectures making impacts on the development of teachers' pedagogical content knowledge

在目前全国轰轰烈烈"做微课、赛微课"的大潮流中,教师在参与微课的设计与制作时,教师的学科教学知识的使用情况如何?文章以外研社第三届教学之星大赛的六位参赛教师为研究对象,通过情境调查问卷、课堂观察方法、半结构访谈法作为研究工具,观察分析了六位教师的微课和访谈语录,评估教师在设计、制作微课时PCK的使用情况。研究发现,在微课的设计与制作过程中,教师的PCK在教学目标知识、学生知识、教学方法、课程知识及评价知识方面得到了提高。

In the trend of more and more teachers are involved in making micro lessons to teach or compete,this paper attempts to discover what effects making and designing micro lessons may bring to teachers' pedagogical content knowledge(PCK).The paper used case study research to examine the micro lessons and interviews of six teacher contestants in a national-level teaching competition by questionnaire,interview and observation.The result turned out that all six teachers' PCK levels have been enhanced in terms of teaching objective knowledge,student knowledge,knowledge of methodology,discipline and evaluation.
