就高中化学学科来讲,并不是所有的内容都可以制成微课视频,这主要是因为高中的教学结构呈现螺旋上升的基本形式,其中有很多内容需要学生在交流与讨论、实验与总结中才能实现认知,因此不能仅以微课的方式来教学。所以微课制作之前,教师要做好选题工作,下面笔者就以必修1“氨气的制备实验”为例介绍微课的制作和使用。一、微课设计对微课进行设计之前,教师要研究课程标准,明确
In the field of high school chemistry, not all content can be made as a mini-video. This is mainly because the teaching structure of high school shows a spiraling basic form, many of which require students to communicate and discuss, experiment and summarize To achieve cognitive, so can not only micro-class teaching. Therefore, before the production of micro-class, teachers should do a good job topics, the author will be following 1 compulsory 1 “ammonia preparation experiment ” as an example to introduce micro-class production and use. First, micro-class design Micro-class design before, teachers should study the curriculum standards, clear
