美国心理学家布鲁纳曾说:“学习的最好刺激乃是对新学知识的兴趣”。 由于数学固有的抽象性强等原因,常给人以枯燥之感,感情是智力发展的翅膀,教学一定要设法引起学生学习的愉快情绪,如好奇、喜悦、趣味、激动等。正如列宁所预见的,“没有人的感情,就从来也不可能有人对于真理的追求”。 American psychologist Bruner once said: “The best stimulation for learning is the interest in new knowledge.” Because of the inherent abstractness of mathematics, it often gives people a sense of boringness. Feelings are the wings of intellectual development. Teaching must be able to arouse students’ happy feelings of learning, such as curiosity, joy, fun, and excitement. As Lenin had foreseen, “no one can never pursue the truth without the feelings of others”.
