实践活动能更有效激发学生的学习兴趣,变“让我学”为“我愿学”。由于数学知识比较抽象,学生不易理解,缺乏兴趣,在教学中,教师可利用小学生“好奇、好动”的心理,从学生熟悉的生活情境和感兴趣的事物出发,提供观察和体验的机会,充分发挥学生学习的自觉能动性,在兴趣盎然操作过程中获取“活”的知识,使所学知识活学活用,实现高效数学课堂教学的梦想。一、让学生动手操作小学生的认识过程是一种再生产过程。如果教师能为 Practical activities can more effectively stimulate students’ interest in learning, change “let me learn ” as “I would like to learn ”. Due to the relatively abstract mathematical knowledge, students are not easy to understand and lack of interest. In teaching, teachers can use the psychology of pupils “curiosity, pampering ” to provide observation and experience from the students’ familiar life situations and interests Opportunity, give full play to the initiative of students to learn, in the course of the operation of interest to obtain “living ” knowledge, so that learning knowledge and learning to use, to achieve efficient mathematics classroom teaching dream. First, to enable students to operate primary school students cognitive process is a reproduction process. If the teacher can do it
