苏教版课程标准数学实验教材四年级(上册)安排了“怎样滚得远”的实践与综合应用。这一内容主要让学生自己去研究斜坡与地面成什么角度时,物体从斜坡滚下在地面上滚动的距离较远。传统的教学重理论轻实践,一定程度上造成了我们的学生强于基础、弱于应用,强于答卷、弱于动手,强于考试、弱于创造。我们的教师何尝不是传统教学中成长起来的呢?认识到了这一点,几位同事决定进行“下水实验”。实验对场地和滚动物的材质等干扰因素做了控制,对实验结果整理并制作了统计
Sujiao version of the curriculum standard mathematics experimental teaching fourth grade (the first volume) arranged “how to roll far ” practice and comprehensive application. This content is mainly for students to study the slope and the ground into what angle, the object rolling off the slope rolling on the ground a long distance. The traditional teaching theory of light practice, to some extent caused our students stronger than the foundation, weaker than the application, stronger than the answer sheet, weaker than hands-on, stronger than the exam, weaker than the creation. Did our teacher not grow up in traditional teaching? Recognizing this, several colleagues decided to conduct a “launching experiment.” Experiments on the venue and rolling materials and other interference factors have been controlled, the results of the experiment and compiled statistics
