数学活动经验的出现拓宽了我们的认识视野。数学活动经验与数学知识最为本质的区别就是主观与客观的区别,更倾向于个性化的体验与感受,是个体直接或者间接经历数学活动而获得的经验。数学活动经验既有认知,也有思维和情感方面的经验。可以毫不犹豫地讲,只有在教学中关注学生的数学基本活动经验,学生才可能会有更加真实而丰富的感受和体验。教学《整数除小数》,在计算每千克苹果多少元时,我让学生自己去探究、交流9.6÷3的结果。结果出来后,孩子们富有个性、丰富多彩的答案,令人赞叹。师:能选出一个代表,把你们的想法告诉全班同学吗?生:计算1千克苹果多少元,列式为9.6÷3,可以分开来考虑,用
The emergence of mathematical activity experience broadens our horizons. The most essential difference between mathematical activity experience and mathematical knowledge is the difference between subjectivity and objectivity. It is more inclined to personal experience and feeling, which is the experience gained by an individual directly or indirectly through mathematical activities. Mathematical activities experience both cognitive, but also thinking and emotional experience. It can be said without hesitation that only when students are concerned with the basic activities of mathematics in teaching can students have more real and rich feelings and experiences. Teaching “Integer Divide Decimals” When calculating how many dollars per kilogram of apples I asked the students to explore and communicate 9.6 ÷ 3 results. The results come out, the children full of personality, rich and colorful answer, it is amazing. Teacher: Can you choose a representative to tell your classmates? Student: Calculate the number of 1kg apples, formula is 9.6 ÷ 3, can be considered separately, with
