化学学科本身具有教学资源丰富多样,图片、视频、实验演示等多媒体信息量大等特点,在课堂教学中,教师总要运用一定的媒体技术向学生呈现、传递教学内容和信息甚至组织课堂教学活动,以丰富学生感知,增强教学效果。解题是化学学科在某一层面上的理论与实际的联系,是学与用的初级过程。这是一种模拟实际的应用练习,在假定的“实际”情景下去分析、解决问题,并通过这一系列的“应用”来培养和提高学生的素养和能力。近年来,在化学课堂教学中呈现教学信息的主流技术是多媒体课件,传统的课件存在许多难以克服的缺陷,学校的课堂教学迫切地需要一种能集黑板和多媒体之长的技术,交互式电子白板应运而生。
Chemistry has its own rich and varied teaching resources, such as large amount of multimedia information such as pictures, videos and experimental presentations. In the classroom teaching, teachers always use certain media techniques to present to students, convey teaching contents and information and even organize classroom teaching activities , In order to enrich the student’s perception, enhances the teaching effect. Problem solving is a chemical discipline in a certain level of theory and practice, is the primary process of learning and use. This is a realistic application exercise that analyzes and solves problems in hypothetical “actual ” scenarios and develops and enhances student literacy and competence through this series of “apps.” In recent years, the mainstream technology of presenting teaching information in chemistry classroom teaching is multimedia courseware. There are many insurmountable defects in the traditional courseware. The classroom teaching in schools urgently needs a technology that can gather blackboard and multimedia, interactive electronic Whiteboard came into being.
