美国心理学家吉尔福特指出:“应该在教学中培养学生的发散性思维”。发散性思维是一种创造思维,它可以从一点出发,运用所学过的基础知识进行放射性联想,由此及彼,由表及里,举一反三,触类旁通。那么在教学中就要引导学生“纵横联系,广泛联想”,拓宽学生思维 American psychologist Gilford pointed out: “The divergent thinking of students should be cultivated in teaching.” Divergent thinking is a kind of creative thinking. It can start from one point and use the basic knowledge that has been learned to make radioactive associations. From this point on and off, it can be considered as an analogy. In the teaching, we must guide students to “connect with each other and broadly associate” to broaden students’ thinking.
