由于初中生在生理和心理方面都存在着各种差异,他们的知识基础和思维能力也不尽相同,因此根据他们的这种差异进行分层教学是十分必要的。所谓“分层教学”是指根据学生的数学基础和思维能力进行分层,对不同层次的学生进行差异性教学。分层教学是因材施教的具体应用,能够激发学生学习数学的兴趣,提高教学成果。 Because junior high school students have various physical and psychological differences, their knowledge base and thinking ability are not the same, so it is necessary to carry out layered teaching according to their differences. The so-called “stratified teaching” means stratifying according to the students’ mathematics foundation and thinking ability, and conducting differential teaching to students of different levels. Hierarchical teaching is a specific application of teaching students in accordance with their aptitude. It can stimulate students’ interest in learning mathematics and improve teaching results.
