巧妙的新课导入,能起到承上启下,促进知识掌握和巩固的作用。《数学课程标准》提出:要使数学教育面向全体学生,实现不同的人在数学上得到不同的发展。这表明,一线教师应当充分正视学生之间存在的差异,并在课堂教学中加以研究,进而合理利用。数学学习活动本应当是一个生动活泼、主动和富有个性的过程,针对学生的差异因素,在课堂教学中,教师采取合理的差异教学策略安排,将有利于学生更好地掌握数学知识。
The introduction of ingenious new courses can play a role in supporting and facilitating knowledge and consolidating. The Mathematics Curriculum Standard puts forward: In order to make mathematics education accessible to all students, different people should be given different development in mathematics. This shows that front-line teachers should fully face up to the differences existing among students and study them in classroom teaching so as to make rational use of them. The mathematics learning activity should have been a lively, active and individualized process. According to the differences of students, in the classroom teaching, the teachers should adopt reasonable teaching strategies to make the students better grasp the mathematics knowledge.
