电教媒体具有形象、直观、生动,声、光、色、形兼备,静动结合等诸多优点,在小学数学教学过程中恰当地运用电教媒体的这些特点,可使学生快速、高效地获取知识,发展思维、形成能力。但有不少数学课堂上使用电教手段的效果并不理想,其中很重要的原因就是没有能够根据学生的认识规律、心理特点、教学内容、学生学习实际等诸多因素去综合考虑。我们只有选取最恰当时机使用电教媒体去教学,才能使电教媒体真正能成为数学教学的好助手。下面结合教学实践谈谈应如何恰当使用电教媒体去教学。
Audio-visual media possesses many advantages such as vividness, visualization, vividness, sound, light, color, shape and combination of static and dynamic. The proper use of these features of the audio-visual media in the process of elementary mathematics teaching can make students acquire knowledge quickly and efficiently, Develop thinking, ability formation. However, there are quite a few mathematics classrooms that use the means of electric education, which is not very satisfactory. One of the most important reasons is that they can not be considered synthetically according to students ’cognition, psychological characteristics, teaching contents and students’ learning actualities. We only choose the most appropriate time to use audio-visual media to teaching, in order to make audio-visual media can really become a good assistant to mathematics teaching. The following combination of teaching practice talk about how to properly use audio-visual media to teaching.
