学生的兴趣爱好、潜在能力、学习方法、基础知识状况、学习动机、智力水平等存在差异,其领悟教学内容的情况也就参差不齐,并且每个班里学生人数数量太大,假如教师按照中等学生的水平授课,那么长此以往,对于优秀学生来说其能力得不到有效的提升,对于后进生来说也赶不上教师的进度,最基本的知识也掌握不了,不能实现全体学生的素质整体提高的目标。 Students’ hobbies, potential abilities, learning methods, basic knowledge, motivation, intelligence level and so on are different, and their understanding of teaching content is uneven, and the number of students in each class is too large. If teachers follow the Secondary school level teaching, then the long run, the ability of outstanding students can not be effectively improved, for backward students can not keep up with the progress of the most basic knowledge can not grasp, can not achieve the overall quality of all students to improve aims.
