近几年,普通高中进行扩招,优质生不断涌入,使得学生在基础方面存在了巨大差距,两极分化情况严重。面对这个现状,教师很难依据学生之间基础与接受能力的差异,不同个性与心理来进行具有针对性的教学,现行的方法基本上还是取好、中、差三部分中偏上进行“一刀切”的方法教学。这种教学方式不利于发挥学生在教师教学过程中所能起到的主体作用,也不利于学生对数学学科的兴趣培养,更加不利于教学质量的提高,违背了“因材施教,循序渐进”的原则,有可能会导致两极分化的日益严重,这不符合现代化教育的要求。面对这个现状,现在试行的“分层教学”课改应运而生。 In recent years, enrollment expansion has been carried out in ordinary senior high schools and inflow of quality students has continued. As a result, there has been a huge gap between students in terms of basic aspects and the situation of polarization has been grave. In the face of this situation, it is very difficult for teachers to conduct targeted teaching based on differences in students’ basic and receptive abilities, different personalities and psychology, and the current methods are basically still good ones. “One size fits all” method of teaching. This kind of teaching method is not conducive to giving play to the main role that the students can play in the teaching process of teachers, nor is it conducive to the students’ interest in mathematics, nor is it conducive to the improvement of teaching quality, contrary to the principle of “teaching students in accordance with their aptitude”. Principle may lead to a worsening polarization, which is not in conformity with the requirements of modern education. Faced with this status quo, the trial now “hierarchical teaching ” curriculum reform came into being.
