小学数学电教课由于使用不同于一般的教学手段和媒体,因此在教学中要使电教手段发挥其最大的功能。取得最佳的效果,还应注意电教课的特殊性,处理好以下几个关系。 一、要正确处理好直观与抽象的关系 电教手段的优越性之一,就是以其鲜艳的色彩、形象、生动直观化的表现力,吸引学生的注意,达到以简驭繁的教学效果。然而直观、形象的演示,只能达到形象思维的低级水平,所以要处理好直观与抽象的关系,要突出教学内容的本质特征,不能为生动而直观,不能停留在直观上,而应通过直观这一手段达到抽象的目的。
Because of using different teaching methods and media from the ordinary, the primary mathematics teaching should make the teaching of audio-visual education play its utmost function. To obtain the best results, but also pay attention to the particularity of electronic teaching, handle the following relationships. First, we must correctly handle the relationship between visual and abstract The superiority of the means of audio-visual education, that is, with its vivid colors, images, vivid and intuitive expression of power to attract students' attention to achieve the teaching effect of simple Yu-fan. However, the demonstration of visual and image can only reach the lower level of image thinking. Therefore, to handle the relationship between visual and abstract, we should emphasize the essential characteristics of the teaching content, which can not be vivid and intuitive, but can not stay intuitively. Instead, This method achieves the abstract purpose.
