老师把多媒体演示当作搞活一节课的主轴,无论上什么类型的课,都要拿出多媒体课件,滥而劣的课件影响了教学任务的完成,忽略了知识点的落实,使学生找不到中心,达不到理想的教学效果。多媒体当作工具,如同粉笔、教材一样,不能以为它是万能的教学工具。 The teacher regarded the multimedia presentation as the key to invigorate a class. Regardless of what type of class, multimedia courseware should be taken out. Overuse of inferior courseware has affected the completion of teaching tasks, neglected the implementation of knowledge points and made students not looking for To the center, reach the ideal teaching effect. Multimedia as a tool, like chalk, textbooks, can not think it is a universal teaching tool.
