教师要让学生在熟悉的生活情境中学习化学,帮助学生从科学、技术和社会相互联系的视角认识化学,落实贴近生活、联系实际的教学要求,增强学生的社会责任感。激发学生的认知冲突,激发其探究欲望,使学生的学习过程围绕着具有科学性的并能激发学生思维的问题而展开。 Teachers should enable students to learn chemistry in familiar life situations, help them to understand chemistry from the perspective of science, technology and social interdependence, and implement life-related and practical teaching requirements so as to enhance students’ sense of social responsibility. Stimulate students’ cognitive conflicts, stimulate their desire to explore, and make the students’ learning process revolve around the problem of being scientific and inspiring students’ thinking.
