一、化学课堂上应用多媒体技术的必要性1.借助多媒体技术,激发学生学习兴趣,增加教学容量多媒体教学具有声情并茂、视听结合的特点,不仅增加了课堂教学的知识内容,而且能够调动学生的各种感觉器官参与教学活动,变抽象为形象,化繁为简,使学生学得快、记得牢,加快了学习进度。2.有利于突破教学难点,微观知识形象化,特别适合于微观领域内容的教学化学是研究物质的组成、结构、性质和变化规律的科学。化学概念及原理大多较为抽象,物质的微观结构既看不见,又摸不着,且化学变化
First, the need for the application of multimedia technology in chemistry classroom 1. With the help of multimedia technology, to stimulate students’ interest in learning and increase teaching capacity Multimedia teaching has the characteristics of both emotional and audiovisual, not only increased the knowledge content of classroom teaching, but also to mobilize students Of various sensory organs to participate in teaching activities, change the abstract image, simplify the complex, so that students learn fast, remember jail, and speed up the learning progress. 2. conducive to a breakthrough in teaching difficult, microscopic knowledge of visualization, particularly suitable for the content of the field of micro-chemistry teaching is the study of the composition, structure, nature and changing laws of science. Most of the chemical concepts and principles are more abstract, the material microscopic structure can not see, can not touch, and chemical changes
