兴趣是最好的老师,我国著名数学家华罗庚说过:“有了兴趣就会乐此不疲,好之不倦。”而学生的兴趣源自于具体情境。因此教师应从创设课堂情境下功夫,尤其是要创设数学趣味情境来激发学生的学习兴趣。一、创设悬念情境,激发学生兴趣从心理学的角度讲,刚上课时学生精力最不集中,在这段时间教师如果直接进行授课,很难让学生快速进入学习状态。因此在导入新课时教师应精心创设教学情境,把学生带入学习情境中。如我在“平方差公式”的教学中,导入新课时,设计了一个小竞 Interest is the best teacher, Hua Luogeng, a famous mathematician in China, said: “If you are interested, you will never tire of it, and you will never tire of it.” And students’ interest comes from the concrete situation. Therefore, teachers should create new classroom situations, especially to create mathematical interesting situations to stimulate students’ interest in learning. First, the creation of suspense situations to stimulate student interest From a psychological point of view, just the class concentration of students in the most concentrated, during this time if teachers direct teaching, it is difficult for students to quickly enter the learning state. Therefore, teachers should carefully create teaching situations and bring students into learning situations when introducing new courses.
