从学生思维特点出发、从数学教学本质出发,选择适当的教学手段进行有效的教学思想渗透教学。尤其是对于概念、运算法则、公式含义及其内在关系的理解和把握可以通过“形”与“数”的某些内在的联系,形成有效的数形结合教学手段,来帮助学生缩小对抽象数字、概念公式等的认识间隙,真正从一定程度上理解知识的内涵。在使用“数形结合”教学思想时更需要我们辩证的理解和对待,践行教学实效性。
Starting from the characteristics of students thinking, starting from the nature of mathematics teaching, select the appropriate teaching methods for effective teaching ideas infiltration teaching. Especially for the understanding and grasping of concepts, algorithms, formulas and their inherent relations, we can form some effective connection between digital form and teaching by means of some internal relations between “form ” and “number ” to help students Narrow the gap between the number of abstract figures, conceptual formulas, etc., really understand the connotation of knowledge to a certain extent. It is even more necessary for us to understand and treat dialectically when using the teaching idea of “combination of numbers and forms” and practice teaching effectiveness.
