近年来,随着普通高中的扩招,中等职业学校的生源素质逐年下降,学生知识水平参差不齐,学习动机、求知态度、学习方法等方面的差异也十分明显。文化课在教学中与专业课相比显得十分困难,尤其是数学,其抽象性、概况性、逻辑性对学习数学提出了更高的要求。原来的教学模式已经不能适应目前的教学现状。为了使不同水平的学生在学校都能得到发展,达到素质教育的目标,实施分层教学是行之有效的教学方法。 In recent years, with the enrollment expansion in ordinary high schools, the quality of students in secondary vocational schools has been declining year by year, and the knowledge level of students has been uneven. The differences in learning motivation, knowledge attitude and learning methods are also obvious. Compared with the specialized courses, the culture class is very difficult in teaching. Especially mathematics, its abstractness, generality and logic put forward higher requirements on the study of mathematics. The original teaching mode can not adapt to the current teaching status quo. In order to make different levels of students can be developed in schools to achieve the goal of quality education, the implementation of hierarchical teaching is an effective teaching method.
