基于三重表征的化学教学行为分析——以微课网“原电池”微视频教学为例

Chemistry Teaching Behavior Analysis Based on Triple Representation——Taking the “primary battery” Micro Videos from China's Micro Class Network as an Example

随着信息技术的发展,微视频逐渐出现于理科教育的实践领域中。论文根据化学学科特征,利用三重表征的化学教学行为评价方法对中国微课网"原电池"相关微视频进行了比较与分析,在化学微视频的微观教学行为、不同表征水平之间的转换和表征的高效性等方面得到相关启示,以期能提高化学微视频的教学质量,促进微视频在教学中的应用。

With the development of information technology,micro video gradually appeared in the practicing field of basic education. According to the characteristic of chemistry discipline,this paper makes a comparison and analyzes the micro videos about primary battery by using the chemistry teaching evaluation of triple representation from China＇s micro network class. Some enlightenments can be obtained based on the analysis of chemistry micro teaching behaviors,translation between different levels and representation efficiency,etc. It can greatly improve the quality of chemical micro video and promote the use of micro video in teaching.
