工业生产类化学教学素材的教学价值开发——以硫酸工业为例

Development of Teaching Value of Chemical Industry Production: Sulfuric Acid Industry as Example

工业生产是化学学科对社会贡献的重要体现,是化学教学重要的素材来源。利用工业生产素材进行教学时,首先需要进行素材本体分析,可以从物质转化和基于化学反应原理的反应调控2个角度分析生产过程中的化学知识,并借助历史发展线索了解不同科学技术发展阶段对工业生产中化学反应选择及原理应用的影响。其次,依据不同学段的课标要求,对素材本体分析结果进行筛选重组,确认教学目标。而后,结合素材内容从物质转化和反应调控2个角度抽提教学关键问题,进行能力活动设计。教学实践结果证实了工业生产教学素材开发思路的有效性。

Industrial production is an important embodiment of the contribution of chemistry to society and an important source of material for chemistry teaching.When developing teaching materials for industrial production,chemical knowledge in the production process can be analyzed from the perspectives of material transformation and reaction regulation based on chemical reaction principle,and the influence of scientific progress and technological renewal on chemical reaction selection and principle regulation in industrial production can be realized with the help of historical development clues.According to the requirements of the curriculum standards,the analysis results of industry material were screened and reorganized to confirm the teaching objectives.Then,the key issues of teaching were extracted,and the ability activity design was carried out.The result of teaching practice proved the validity of the idea of developing teaching materials for industrial production.
