二年级期末数学试卷上有这样两道填空题:一包牛奶大约重()克,一个苹果大约重()克。从卷面上看,有95%的答案与正常范围相距甚远。牛奶、苹果都是学生耳熟能详的食品,为何差异这么大呢?究其原因,是教师在教学活动中忽视了学生的实际生活,没让学生亲自体验1克物品到底有多重,10克、20克物品有多重……导致学生不能用数学眼光观察周围世界,只有机械地学习数学,隔离了数学与生活的联系。
The second grade mathematics papers have such two fill in the blank questions: a pack of milk about weight () grams, about an apple weight (g). From the surface, 95% of the answers are far from the normal range. The reason is that teachers neglect the actual life of students in teaching activities, did not allow students to experience 1 gram of goods in the end have multiple, 10 grams, 20 grams The multiplicity of items ... cause students not to look mathematically at the world around them, learn math mechanically, and isolate the connection between math and life.
