根据具体的教学内容,课堂上灵活运用“数学实验”能改变教师的教学方式与学生的学习方式,有效提高课堂教学效率。数学实验课的组织方式大致可以分为四类:观察比较式、探究发现式、实践操作式、规律研究式。《怎样滚得远》一课属于实践操作式,其基本流程可以分为以下几步:出示问题情境,引发探究内驱——审视实验步骤,操作实验材料——采集记录实验数据,作出初步分析——拓展分析素材,得出基本结论——联想类比,延伸运用。根据这一基本模式,本
According to the specific teaching contents, the flexible use of “Mathematics Experiment” in the classroom can change the teachers ’teaching methods and students’ learning styles, and effectively improve the efficiency of classroom teaching. Mathematical experiment class organization can be divided into four categories: observation and comparison, explore discovery, practice and operation, regular research. The course of “How to go far” is a practical operation. The basic process can be divided into the following steps: Presenting the problem situation, initiating the exploration of the internal drive - Examining the experimental steps, manipulating the experimental materials - Collecting and recording the experimental data to make a preliminary analysis - Expand the analysis of material, draw the basic conclusion - Legend analogy, extension of use. According to this basic model, Ben
