教师应在每节课的开始就有意识地创设具体生动的教学情景,让学习材料像磁石般地吸引学生的注意力,激起学生思维的涟漪。下面说说我在数学课中运用电教媒体创设教学情景的三种做法。 1.联系生活,展示情景。数学本身是抽象的,但数学的原型来源于具体的生活实际。在教学中,教师联系生活实际,运用电教媒体,为学生提供看得见,摸得着,或亲身经历过的具体事例,既可培养学生“数学源于生活”的意识,又可从中体验数学在生活中巨大的 Teachers should consciously create concrete and vivid teaching scenarios at the beginning of each lesson so as to make the learning materials attract the students ’attention like magnets and arouse the ripples of students’ thinking. Here to talk about my math class in the use of audio-visual media to create teaching scenarios of the three practices. 1. Contact life, show the scene. Mathematics itself is abstract, but the mathematical prototype comes from the actual life. In teaching, teachers contact with the reality of life, the use of audio-visual media, to provide students with visible, touching, or experience the specific examples, not only can cultivate students “mathematics from life ” awareness, but also from Experience math in life is huge
