真实情境下素养为本的“氯及其化合物”教学——含氯消毒剂在自来水消毒中的应用

Core Literacy Oriented Teaching of Chlorine and Its Compounds Based on Application of Chlorine Containing Disinfectant in Disinfection of Tap Water

通过对课标、教材、课例论文和高考试题中含“氯”真实情境的统计分析,呈现真实情境选取的流程图和基于含“氯”真实情境设计教学的流程图。创设“含氯消毒剂在自来水消毒中的应用”贯穿式真实情境,利用学生熟悉的“水”开展多维实验探究活动,在问题解决下认识氯及其化合物在生产生活中的应用价值,有效落实素养为本的课堂教学。

Through statistical analysis of the real situations containing“chlorine”in the curriculum standards,textbooks,papers,and college entrance examinations,a flowchart for selecting the real situation and a flowchart for designing teaching based on the real situation containing“chlorine”are presented.This paper creates a real scenario of“application of chlorine disinfectants in tap water disinfection”,utilizing students'familiar“water”to conduct multidimensional experimental exploration activities,and understanding the application value of chlorine and its compounds in production and life through problem-solving,effectively implements literacy-based class teaching.
