摘要
中小学实验教学中普遍存在课堂时间有限,实验资源不足,实验教学容易流于形式,甚至只关注结果而忽视实验过程和细节等问题。在这个背景下,微课以其短小精悍、聚焦知识点、可重复播放的特点尝试改善该教学困境。文章具体阐述了"实验演示型微课"的三方面认识、四大特点、五个设计步骤,并结合优秀的微课案例分析了它的设计与应用技巧。
In the experimental teaching of primary and secondary schools,there are some problems：1.limited time in the classroom;2.insufficient experimental resources;3.the experimental teaching is easy to be a mere formality,and even only concerns with the results and ignores the experimental process and details.Under this background,we try to use micro-lectures to improve the teaching difficulties,as micro-lectures possess the following characteristics： short and pithy,focusing on knowledge points and able to playback repeatedly.This paper expounds three understandings,four characteristics and five design steps of ＂experimental demonstration micro-lecture＂,and combines excellent micro-lecture cases to analyze its design and application skills.
