随着现代科学技术和教育事业的不断融合,新型高效的电教媒体教学工具在现代小学数学导课设计中的应用越来越广泛,这引起了相关教育部门的高度关注。本文通过科学地分析了电教媒体对于小学数学导课设计的帮助作用以及其在小学数学导课设计中的使用方法,从而科学地探究电教媒体支持下的小学数学导课设计质量优化方法。 With the continuous integration of modern science and technology and education, the new and effective teaching tools of audio-visual media are becoming more and more widely used in the design of modern primary school mathematics lesson guidance, which has aroused great concern from relevant education departments. This paper scientifically analyzes the help function of audio-visual media for primary school mathematics lesson planning design and how to use it in elementary mathematics lesson planning so as to scientifically explore the quality optimization method of primary school mathematics lesson planning supported by audio-visual media.
