今年是广东省新课程改革实施的第七年,也是研究者在经历两轮高中的小循环后第三次接手高一的教学工作。面对教与学呈现的新问题发现通过借鉴PCK结构的研究,优化辨析活动,对推动学生自主思考来提升思想政治课的有效性有所裨益。 This year marks the seventh year of the implementation of the new curriculum reform in Guangdong Province and the third time that the researchers took over the first year after experiencing the two cycles of high school. In the face of the new problems of teaching and learning, it is found that using the research of PCK structure and optimizing discrimination activities can be helpful to promote the students’ independent thinking to enhance the effectiveness of the ideological and political lesson.
