认知心理学家布鲁纳认为:“学习的最好刺激是学生对所学材料的兴趣。”兴趣就像最好的老师把学生引进知识的海洋。只有学生感兴趣,才喜欢学,也才能学得好。作为一名数学教师,每上一节课前我都在思考:怎样才能让我的学生对那枯燥单调的十个数感兴趣?怎样才能让我的学生对这门“冷血”学科有兴趣?实践证明:只有从学生生活中来的数学才是“活”的数学、有意义的数学,学生才会感兴趣。我在教学《生活中的负数——温度》一节课时,我问学生:“在生活中我们会感到冷和热,这是为什么呀?”学生答到:“温度变化。”接 According to Bruner, a cognitive psychologist, “The best stimulus for learning is the student’s interest in what he or she learns about.” “Interest is like the best teacher bringing students to the ocean of knowledge. Only students interested, just like learning, but also to learn well. As a math teacher, every time before the last class, I was thinking about how to get my students interested in the boring monotonous ten numbers and how to make my students have the right to this ”cold-blooded“ subject Interest? Practice has proved that students will be interested only if the mathematics from the student life is ”living“ mathematics, meaningful mathematics. When I was teaching ”Negative-Temperature in Life“, I asked the student: ”We feel cold and hot in our life. Why is this?“ ”The students answered: " Pick up
