微课,即为微型视频课程,是以短小的视频内容为主要的教学方式。微课是近年来教育家们研究发现的一种情景化的极有效的教学方法,时间极为短暂十分钟以内,利用视听结合的方法,引发学生的积极性,激发学生的学习兴趣。微课在初中化学中的应用十分广泛,教师利用微课帮助教学,让原本抽象难懂的化学和化学实验变得更为具体,学生可以通过微课了解化学实验的操作步骤,让化学更加简单易懂,弥补了原本教学中的缺陷,增强了学生学 Micro-class, which is a mini-video course, is based on short video content as the main teaching method. Micro-class is a highly effective teaching method of situationalization discovered by educators in recent years. Time is very short within ten minutes. By using the method of audio-visual combination, micro-class arousing students ’enthusiasm and arousing students’ interest in learning. Micro-class chemistry in junior high school is widely used, teachers use micro-classes to help teaching, so that the original abstract chemistry and chemistry experiments become more specific, students can learn through the micro-chemical experiment steps to make chemistry easier Easy to understand, make up the shortcomings of the original teaching, enhance student learning
