处于同一年龄层次的学生具有相当大的共性,但在其发展过程中又呈现出差异,主要表现在行为习惯、智力水平、个性品质等方面。因此,在同一个班按统一的标准要求学生,搞“一刀切”的教学是不切合实际的。这样会使一些后进生丧失学习的兴趣和动力,又会出现忽视优等生的现象。因此,实施分层递进教学具有多方面的积极意义。 Students in the same age group have quite a lot of similarities, but there are also differences in their development process, mainly in the aspects of behavior, intelligence, personality and so on. Therefore, it is impractical to require students to practice “one size fits all” in the same class according to a uniform standard. This will make some backward students lose interest in learning and motivation, there will be neglected top students phenomenon. Therefore, the implementation of hierarchical and progressive teaching has many positive aspects.
