基于发展化学核心素养的“煤的综合利用”高三复习教学实践与反思

Review Teaching and Reflection of “Multiple Uses of Coal” of Senior Three Based on Developing Core Literacy of Chemistry

以“煤的综合利用”高三复习教学为例，基于化学核心素养确立教学目标，将“化工厂如何解决煤燃烧产生的SO2”“科学家如何选择煤气化的反应条件”这2个问题的讨论作为重点，并详述以上教学环节。对教学的实施和目标的落实进行了总结反思：创设真实情境，有效发展化学学科核心素养；创新教学设计，激发学生学习兴趣；用好问题串，促进知识、思路结构化；精心设计，促进素养显性化。

Taking the review teaching of ＂multiple uses of coal＂ of senior three for example, this paper established the teaching goal based on the core literacy of chemistry, focused on the discussion of following two questions- ＂How did the chemical factory deal with SO2 produced by coal combustion how to select the reaction conditions of coal gasification ＂, and discussed the teaching process in detail. This paper also summarized and reflected on the teaching practice and implementation of the objectives, setting real situations to effectively develop the core literacy of chemistry; innovating teaching design to stimulate students＇ interests in learning; using a string of questions to promote knowledge and thoughts structured; designing a good teaching plan to promote the literacy dominant.
