以“酸雨的防治”为主题的项目式教学设计

Project-type Teaching Design with the Theme of“Prevention and Control of Acid Rain”

在常规教学之中,学生的主动性被忽视,课堂实践也很难实现,无法彻底落实新课改所提出的关于中学化学的核心素养。而项目式教学,通过小组协作的教学方式,进行探究式学习,该教学模式注重将理论迁移应用于实际生活,从而提高学生的实践能力。以酸雨的防治为项目式教学的主题,通过构建酸雨的概述、酸雨的防治及身边雨水pH值的测定这三个任务,对酸雨的形成途径和酸雨的防治进行了探究,有利于强化学生对硫及其化合物的理解,发展学生的处理问题的能力,树立学生的环保理念。

In the routine teaching,the students initiative is ignored,and the classroom practice is also difficult to achieve,unable to completely implement the core quality of middle school chemistry proposed by the new curriculum reform.The project-based teaching,through the teaching method of group cooperation,carries out inquiry learning.This teaching mode focuses on applying theory transfer to real life,so as to improve students practical ability.Taking the prevention and control of acid rain as the theme of project-based teaching,through the construction of three tasks,namely,the overview of acid rain,the prevention and control of acid rain and the determination of pH value of rain around,the paper explores the formation path of acid rain and the prevention and control of acid rain,which is conducive to strengthening students understanding of sulfur and its compounds,developing students ability to deal with problems,and establishing students concept of environmental protection.
