Practice ″Teaching with Textbooks″ based on the concept of ″Three Teaching″:Taking ″Properties of Bisectors of Angles (1)″ in the edition of People′s Education as an example

“用教材教”的教学理念是把教材作为最基本的课程资源和教学线索,这就需要教师整体把握教材.以人教版“角的平分线的性质(1)”为例,基于“三教”理论,将教学内容串点成线,紧扣教材设计教学,从而实现从教材体系向教学体系、最终向学生学科核心素养的转化.

The teaching concept of″Teaching with Textbooks″is to take textbooks as the most basic course resources and teaching clues,which requires teachers to grasp the textbooks as a whole.Taking″Properties of Bisectors of Angles(1)″in the edition of People′s Education as an example,based on the concept of″Three Teaching″,the teaching content is connected from the points to a series of lines,and the teaching design is closely related to the textbooks,so as to realize the transformation from the teaching material system to the teaching system and ultimately to the core literacy of the students′disciplines.
