目前,我们广大教师正在为“减负增效”落实自己的实际行动,但落后的教学手段限制了一节课的容量,要提高教学质量仅靠原有的教学资源明显是不够的。那么有没有更好的教学手段来改变以往教学质量低的局面呢?从调查和实践来看,新生事物多媒体有着传统教学手段无法比拟的优势,而且已被许多教师所运用。尤其是抽象的数学课堂的教学更需要多媒体的介入,从而为优化数学课堂教学服务。 At present, most of our teachers are implementing their own practical actions to reduce the burden and increase efficiency. However, backward teaching methods limit the capacity of a lesson. To improve the quality of teaching, it is obviously not enough to rely solely on the original teaching resources. So there is no better teaching methods to change the situation of low quality of teaching in the past? From the survey and practice point of view, the new things multimedia has the advantage of traditional teaching methods can not be compared, and has been used by many teachers. In particular, the teaching of abstract mathematics classrooms need more multimedia intervention, so as to optimize the mathematics classroom teaching services.
