文章就目前高职院校因扩招造成的生源数学基础普遍薄弱的现状,以及在教学过程中教师因学生数学基础参差不齐而造成的尴尬局面,提出了通过分层教学来解决问题的必要性,并阐述了如何进行分层,如何改革教学内容、教学手段、评价手段,真正实现以“学生为本,因材施教”的教学理念。通过对学生的分层教学,实现各个层次的学生都能够真正受益,从而提高教学质量,提高学生的数学素养。 This article puts forward the necessity of solving the problems through the teaching in layers because of the weakness of maths universally existing in higher vocational colleges due to enrollment expansion and the embarrassment of teachers caused by the uneven mathematical foundation of students in the teaching process , And explained how to stratify, how to reform the teaching content, teaching methods, evaluation methods, and truly realize the teaching concept of “student-oriented, teaching in accordance with their aptitude”. By teaching students in different levels, all levels of students can really benefit, so as to improve teaching quality and improve students’ mathematical accomplishment.
