发挥化学的学科优势,紧密结合社会生活中遇到的化学现象,引导学生积极主动的探求化学知识与技能,形成自身独特的学科价值观和思考解析问题的能力,应当是化学学科高效课堂的重要任务.基于知识与实践结合、学识与探析结合,建构“问题驱动”教学模式,通过多向互动,有效激发学生在课堂内外的学习兴趣,提升学生能动学习和知识探析能力,以及有效培养学生的知识探索自信和社会认知自信,是化学学科形成高效课堂模式的重要支撑. It is an important task for an effective course in chemistry to give full play to the subject advantages of chemistry and closely integrate with the chemical phenomena encountered in social life so as to guide students to actively explore chemistry knowledge and skills, form their own unique subject values ​​and think and analyze problems Based on the combination of knowledge and practice, combining knowledge and exploration, we construct a “problem-driven” teaching mode and effectively stimulate students ’interest in learning both inside and outside the classroom through multi-directional interaction so as to enhance students’ ability of active learning and knowledge exploration and effectively train students The exploration of self-confidence and self-confidence in social cognition is an important support for the formation of an efficient classroom model in chemistry.
