每个学生之间都存在着个体差异、智力差异、学习基础差异、学习品质差异。这些差异会导致初中学生的数学学习存在两极分化现象,而课堂式教学采用“一刀切”的授课方式,很难面面俱到,使各个层面的学生都有提高。所以,教师有必要根据学生的数学基础、智力水平以及学习的主动性,进行分层教学,这样有利于使各个层面的学生互相激励、共同进步。 There are individual differences, intellectual differences, basic learning differences, and different learning qualities among each student. These differences lead to the polarization of mathematics learning among junior high school students. However, classroom teaching adopts “one size fits all” teaching methods, so it is hard to cover all aspects of students’ learning at all levels. Therefore, it is necessary for teachers to conduct the teaching in different levels according to the students’ maths, intelligence and initiative in learning so as to encourage all levels of students to motivate each other and make progress together.
