学生对概念的掌握和理解是数学教学的重要目标。它包括两个方面:一方面是能理解知识之间的相互关系,并能灵活变通;另一方面是能应用知识解决问题。概念教学是学生后续学习的基础,所以探明学生对概念知识的学习程度并进行巩固教学尤为必要。片段回放:当学生学习了三角形、平行四边形的概念,知道组成三角形的三条边特征后,教师安排这样的巩固教学。
Students grasp the concept and understanding of mathematics teaching is an important goal. It includes two aspects: one is to understand the relationship between knowledge and flexibility; the other is the ability to apply knowledge to solve the problem. Concept teaching is the basis of students ’follow-up study. Therefore, it is necessary to prove students’ learning level of concept knowledge and consolidate teaching. Fragment playback: When students learn the concept of triangles, parallelograms, know the composition of the three sides of the triangular features, the teacher arranged such consolidation teaching.
