一、高中化学课堂上应用多媒体的必要性1.应用多媒体技术可以激发学生的学习兴趣在讲课时,合理地运用多媒体技术可以有效地激发学生的学习兴趣,改变传统的教学方法,将枯燥乏味的课堂变得生动有趣。通过多媒体技术可以直观生动地将需要讲解的知识展示给学生,进而提高学生的学习兴趣,让学习成为一件轻松愉悦的事情。如在讲解化合反应时,可以利用多媒体生动地展示出化合反应的条件等,用图片将学生不理解的问题展示出来。 First, the need for multimedia in high school chemistry classroom 1. The application of multimedia technology can stimulate students ’interest in learning During lectures, the rational use of multimedia technology can effectively stimulate students’ interest in learning, change the traditional teaching methods, will be boring The classroom becomes lively and interesting. Through the multimedia technology, students can intuitively and vividly demonstrate the knowledge they need to explain, so as to enhance their interest in learning and make learning a relaxing and enjoyable activity.
