皮亚杰的儿童智力发展阶段理论认为,小学生形象思维活跃,逻辑思维较弱,在我们平时教学过程中,要符合学生的心理特点和认知规律。人教版教材较以往变动较大,内容设置更贴近学生的认知规律和生活实际,但在练习题设置中,个别题型让人有一种“教材很重视,教师很为难,学生很迷惑”的感觉。很明显这种题有点超越了大部分学生的理解能力。如何教,教到什么程度,学生该掌握到什么程度,这给老师提出了新的课题,现以二年级下册估算部分的两道练习题为例。
Piaget’s childhood intelligence development stage theory holds that primary school students are active in thinking and weak in logical thinking. In our usual teaching process, they should meet the students’ psychological characteristics and cognitive rules. People’s Education Edition teaching material changes than in the past, the content is set closer to the cognitive rules of students and the actual life, but in practice settings, individual questions people have a “teaching material is very important, teachers are very embarrassed, students confused ”a feeling of. Obviously this kind of question goes beyond the understanding of most students. How to teach, what extent to teach, to what extent the students should master, which posed a new subject for the teacher. Take the two exercises in the second grade of the second volume as an example.
