每个学生都是不同的个体,分层次教学尊重学生的个体差异,面向全体学生,充分挖掘学生的内在潜能,调动学生的学习积极性,激发学生主动参与的欲望,从而提高学生学习的有效性。 Each student is a different individual. Teaching at different levels respects the individual differences of students. For all students, students are fully tapped to develop their potential, arouse students ’enthusiasm for learning, stimulate students’ desire to participate actively, and enhance the effectiveness of student learning.
