现在化学教学的班级学生人数众多,每个人都有独特的学习方式和思维个性,因此,应该对学生提出不同层次的管理和教学要求,提高教学的效率。分层次教学可以根据学生的兴趣差异和学习能力的高低,对教学目标作出相应的调整,以便对不用的学生提供适合自己的学习环境,提高教学质量。 Nowadays there are a large number of students in the chemistry teaching class, each of whom has a unique learning style and thinking personality. Therefore, students should be asked different levels of management and teaching requirements to improve teaching efficiency. The hierarchical teaching can adjust the teaching objectives according to the students’ interest difference and learning ability, so as to provide the students with suitable learning environment and improve the teaching quality.
