在高中化学教学中,适当引入时事性化学知识可以引导学生认识化学在促进社会发展和提高人类生活质量方面的重要作用,从而提高学生的学习兴趣。问题教学模式可以有效调动学生的学习兴趣,激发学生探究学习的主动性,教师在教学过程中的问题设计和应用是问题教学模式能否顺利进行的关键因素。ChemMatters《教师引导手册》的问题模块将学生熟悉的化学概念和将要学习的新知识以不同层次的问题形式呈现,这些问题的设计和使用为教师在讲授新知识的过程中提供丰富的教学资源。
In high school chemistry teaching, the proper introduction of current chemical knowledge can guide students to recognize the important role of chemistry in promoting social development and improving the quality of human life, so as to enhance their interest in learning. The problem teaching mode can effectively arouse students ’interest in learning and stimulate students to explore the initiative of learning. The design and application of teachers’ questions in the teaching process are the key factors for the problem-teaching mode to proceed smoothly. The questions module in ChemMatters’ Teacher’s Guidebook presents students with familiar chemistry concepts and new knowledge to be learned in different levels of questions. The design and use of these questions provide teachers with a wealth of teaching resources in teaching new knowledge.
