侯氏制碱法中的化学——基于生产实际分析的初中化学溶液主题教学

Chemistry in Hou’s Process for Soda Production:Teaching of Solution in Junior High School Chemistry Based on the Analysis of Production Practice

侯氏制碱法是一个理想的基于生产实际分析的教学素材。本主题教学以“溶液”和“盐”的相关知识为学习内容,通过认识侯氏制碱法的原料,配制侯氏制碱法的原料,探秘侯氏制碱法中的变化,了解侯氏制碱法的生产流程等4个任务,开展主题学习。培养多角度解决真实问题的能力,着重发展“证据推理与模型认知、科学精神与社会责任”等化学学科核心素养。

Hou’s process for soda production is an ideal teaching material based on actual production analysis.This topic teaching takes“solution”and“salt”related knowledge as the learning content.Through understanding the raw materials of Hou’s process for soda production,preparing the raw materials of Hou’s process for soda production,exploring the changes in Hou’s process for soda production,and understanding the production process of Hou’s process for soda production,this topic learning is carried out.This paper also cultivates the ability to solve real problems from multiple perspectives,and focuses on the development of core literacy in chemistry disciplines such as“evidence reasoning and model cognition,scientific spirit and social responsibility”.
