微课是一种新型的教学模式,应用十分广泛。微课教学模式先学后教的特点,调整了课内外的学习时间,让学生能够充分利用课堂时间。本文以中学生物课中“种子萌发的环境条件”这一实验为例,针对该实验的微课教学设计及其应用于中学生物实验的可行性、有效性、实践性进行探讨。 Micro-class is a new type of teaching mode, a wide range of applications. The teaching mode of micro-class begins with the characteristics of post-secondary education, adjusts the study time in and out of class, and enables students to make full use of class time. In this paper, taking the experiment of “environmental conditions of seed germination” in biology class of middle school as an example, the paper probes into the design of micro-class teaching and the feasibility, effectiveness and practicality of this experiment in middle school biology experiment.
