【简答题】
. 一位小学自然课教师在给学生讲“磁铁”之前演示了一个“魔术”:一盆水中游着一只“鸭子”(标本)教师手中拿着一块馒头嬉逗“鸭子”,“鸭子”果然紧紧跟着馒头转。学生感到惊奇。教师边演示:“你们想知道这是为什么吗?”学生异口同声地说:“想。”于是教师就从“鸭子”的嘴里取出一块铁片,又从馒头中间拿出一块磁铁。接着他向学生演示了磁铁的两端分别对不同物体的作用,让学生观察、讨论,并总结出磁铁的特性。接着又问学生日常生活中有哪些物品了磁铁,学生纷纷举手,教师请两个平时不爱回答问题的同学回答并表扬了他们。最后,教师要求每个学生思考磁铁在实际生活中的具体,并将设计方案制作出来。 请结合教学基本理论知识,谈谈你对该教师教学成功的认识。
