时常有人这样衷叹:“数学太枯燥、太乏味了!学数学,真没劲!”的确,数学是抽象性、逻辑性很强的一门学科。如果,教师不顾及学科特点及学生的认知水平,只顾自己滔滔不绝,这样一厢情愿的满堂言,只会让课堂像一潭死水,毫无生机。因此,教师要巧用信息技术,给我们的教学注入一汪清泉,活化了我们的数学课堂。1化静为动,活化课堂心理学经验告诉我们:动态的事物比静态的事物更能刺激 Often people are so sigh: “Mathematics is too boring, too boring! Mathematics, really boring!” Indeed, mathematics is abstract, highly logical discipline. If the teacher, irrespective of the characteristics of the subject and the level of his or her cognition, only gives himself a chance to surrender himself, such wishful speech will only make the classroom a stagnant stream of water and vitality. Therefore, teachers should skillfully use information technology to infuse a fresh spring into our teaching and activate our math class. 1 Quiet movement, activation of classroom psychology experience tells us: dynamic things are more exciting than static things
