美国心理学家布鲁纳指出:最好的学习动机是学生对所学知识本身的内部兴趣。兴趣是最好的老师,学习数学也是如此。培养学生学习数学的兴趣,对于学习活动有重要意义,它能推动学生积极思考,提高学习效率和激发更大的学习欲望。而数学又是一门具有高度抽象性、严谨逻辑性的学科,容易给学生造成心理上的枯燥和认识上的障碍。 Bruna, an American psychologist, pointed out: The best motivation for learning is the student’s internal interest in the knowledge he or she learns. Interest is the best teacher, learning math as well. Fostering students ’interest in learning mathematics is of great significance for learning activities, which can promote students’ positive thinking, improve learning efficiency and stimulate greater desire for learning. And mathematics is a highly abstract, rigorous logic of the subject, easy to cause psychological boring and cognitive barriers.
