微课也被称为微型视频课程或微课程,主要是利用短小的教学视频作为发展载体,对某一知识点或者教学环节所开展的一种情景化的教学方式~([1])。微课时间为10 min,内容短小精悍,利用多媒体,声情并茂、图文并存,能够激发学生的感官神经。在初中化学教学中应用微课可以将抽象知识具象化、复杂知识简单化,可以将实验清晰地展现在学生面前,一定程度上弥补了教学中的缺陷与不足。一、应用微课的优势1.激发学生学习兴趣,提高教学质量 Micro-classes are also known as mini-video courses or micro-curriculums. They mainly use short teaching videos as a carrier of development and provide a situational teaching method for a certain knowledge point or teaching link. [1] Micro-class time is 10 min, content is short and lean, the use of multimedia, both voice, graphics co-exist, to stimulate the students’ sensory nerves. The application of micro-class in junior high school chemistry teaching can abstract the abstract knowledge, simplify the complex knowledge, and expose the experiment clearly to the students, to a certain extent, make up for the defects and deficiencies in teaching. First, the application of micro-class advantage 1. To stimulate student interest in learning, improve teaching quality
