化学双语教学微型课程“能量转化”的实践

Bilingual Chemistry Teaching of Micro-Course of Energy Changes

化学双语教学微型课程'能量转化',在高中必修教材基础上对知识进行拓展,分析了化学反应中3种能量转化形式即化学能与光能、热能、电能的转化。内容包括介绍荧光棒的成分和作用原理;学习粗测饼干所含热量的方法,并分析误差原因;了解冷敷创可贴的应用,体会化学原理与实际生产、生活的联系;通过可乐电池的学生实验,进一步认识燃料电池。化学双语教学微型课程'能量转化'分2课时完成,教学实践包括教学目标的确定、教材的编写、2个阶段的教学过程以及实施教学评价等。

Bilingual chemistry teaching of micro-course of energy changes was based on senior high school compulsory curriculum,which analyzed three kinds of energy changes in chemistry reactions,including chemical energy and light,chemical energy and heat,chemical energy and electricity.The main contents were as follows,introducing the ingredient and working theory of glow stick;learning how to measure the heat by burning apiece of biscuit;realizing the relations between chemistry theory and real life by knowing about the cold band-aid;more insight about fuel battery by students’ experiment of cola battery.The whole lesson consisted of two 45-minut period,and the teaching practice concluded the teaching purposes,compiling of teaching materials,teaching progress of two 45-minut classes and implementing teaching evaluation.
