数学概念是学生掌握数学知识、发展智力的基础。因此,应根据数学的学科特点、教材安排的体系及学生的年龄特征,采用恰当的教学方法,加强概念教学。 1.借助旧知识,建立新概念。任何一个概念都不是孤立存在的,如果不从概念的联系与区别中掌握概念,就无法使学生深入了解新概念的含义。因此,借助旧知识建立新概念,可以使概念教学收到事半功倍的效果。 Mathematical concepts are the basis for students to master mathematical knowledge and develop intelligence. Therefore, based on the characteristics of maths, the system of arrangement of teaching materials and the age characteristics of students, appropriate teaching methods should be adopted to strengthen the teaching of concepts. 1. Create new concepts with old knowledge. No one concept exists in isolation. Without understanding the concept from the connection and difference, students can not understand the meaning of the new concept deeply. Therefore, the establishment of new concepts with old knowledge can make the concept teaching more effective.
