根据小学生心理发展特点,尤其是低年级学生,形象思维是主要的思维方式,在数学学习中如何将抽象的知识内化为学生自己的经验,动手操作无疑是最有效最直接的学习方式之一。在教师设计的有效操作活动情境中,引起学生的兴趣,利用有效的学具进行操作,便于学生对抽象的数学知识的直观理解,能更有效的突破重难点,获取活动经验,提升数学思维。 According to the characteristics of pupils ’psychological development, especially for the students in lower grades, the image thinking is the main way of thinking. How to internalize the abstract knowledge into the students’ own experience in mathematics learning is undoubtedly one of the most effective and direct ways of learning . In the context of effective operation of teachers’ design, students’ interest is aroused, and effective learning tools are used to facilitate students’ intuitive understanding of abstract mathematical knowledge. They can more effectively break through heavy and difficult points and gain experience in activities to improve their mathematical thinking.
