数学基本活动经验的积累大致需要经过“经历、内化、概括、迁移”的过程,帮助学生积累数学活动的基本经验是数学教学的重要目标。几年来,我针对不同学段的“数与代数”“空间与图形”“统计与概率”“实践与综合应用”四个领域的内容分别作了不同的实验研究,发现在每个领域都可以积累学生的数学活动经验。一、在“数与代数”中积累学生的数学活动经验北师大版小学五年级上册《质数和合数》一课,课堂上,我设计了这样一个活动:分别让学生用1、3、7、9、
The accumulation of experience in basic activities of mathematics generally needs to go through the process of “experiencing, internalizing, generalizing and migrating”. The basic experience of helping students to accumulate mathematical activities is an important goal of mathematics teaching. In recent years, I have made different experimental studies on the contents of the four fields of “Number and Algebra”, “Space and Graph”, “Statistics and Probability”, “Practice and Comprehensive Application” , Found that in each area can accumulate students’ experience in math activities. First, in the “number and algebra” in the accumulation of students’ experience in math activities Bei Shijiazhuang version of the fifth grade on the book “prime and the number of” a lesson, I designed such an activity: the students were to use 1,3 , 7,9,
