对小学数学课堂而言,教有教的策略,学有学的方法,二者融智慧于一身。新课程数学课堂教学理念也曾提出,“教”和“学”是有机统一体,教中有学,学离不开教。教师在课堂教学中有时也会因学生独到的解题方法而点头称快;有时也会因学生精辟的观点阐述而暗自欣赏。此时的?“教”和“学”在瞬间完成了角色转换,在教师教的过程中学生学到了知识、掌握了技能、养成了习惯,培养了情感。建议设计练习 For elementary mathematics classrooms, there are strategies for teaching and learning, and learning and learning methods, both of which integrate wisdom in one. The new curriculum mathematics classroom teaching concept has also been proposed, “teaching ” and “learning ” is an organic unity, teaching learning, learning can not do without education. Teachers in classroom teaching sometimes due to the students unique way to solve problems and nod; also sometimes implied by students insightful point of view and secretly appreciate. At this moment, the teaching of “teaching” and “learning” completed the role conversion in an instant. During the process of teaching, the students learned the knowledge, mastered the skills, developed the habit and cultivated the emotion. Recommended design practice
