以“全球气候变化对人类活动的影响”教学为例,阐述PCK指导下开展有效教学设计的路径,落实有效教学,促进教师成长与学生学习力提升的教学探索。实践表明,在高中地理教学中引入PCK,有助于实现教学有效与教师成长有效的双赢。 Taking the teaching of “The Influence of Global Climate Change on Human Activities” as an example, this paper expounds the path of effective instructional design under the guidance of PCK, carries out teaching exploration of effective teaching, promotion of teacher growth and improvement of students’ learning ability. Practice shows that the introduction of PCK into geography teaching in high school helps to achieve a win-win effect between teaching effectiveness and teacher growth.
