本课承接传统的教学模式,很好地渗透了新的教学理念。在课程资源、学习方式和科学探究等方面,教者做了有益的尝试。特别是在整合教学资源的基础上设计出清晰的教学线索,引导学生步步紧逼学习目标的做法成为本课的亮点。如果在氯气制备实验活动上再放手一些,让学生根据氯气的特性和已有知识,自主设计实验装置,然后通过合作交流形成共同的实验方案,必将成为一堂真正的探究性课堂。 This lesson to undertake the traditional teaching mode, well infiltrated the new teaching philosophy. In terms of curriculum resources, learning methods and scientific inquiry, teachers made useful attempts. Especially in the integration of teaching resources based on the design of clear teaching clues to guide students to step by step to practice learning objectives become the highlight of this lesson. If we let go of some experiments on chlorine gas preparation and let students design their own experimental devices according to the characteristics of chlorine gas and their existing knowledge and then form a common experimental program through cooperation and exchange, it will surely become a real inquiry-based classroom.
