伴随着计算机信息化的高速发展,多媒体技术已广泛应用于各学科教学之中.多媒体技术能综合处理文字、图形、图象、声音、动画、视频等各种信息,与仅利用黑板、挂图、实验、模型等传统教学手段相比,多媒体技术在内容上更丰富、理解上更直观、表达上更生动,可以增强学生的学习兴趣和加深对知识的理解,对提高课堂教学效率作用明显.本文以高中化学课堂教学为例,结合笔者多年的高中化学教学经历,针对多媒体技术在创设情景、剖析机理、突破难点,优化实验等方面的作用进行探究.
With the rapid development of computer information technology, multimedia technology has been widely used in the teaching of various disciplines.Multimedia technology can comprehensively deal with a variety of information, such as text, graphics, images, sound, animation, video, Compared with the traditional teaching methods such as experiment, model and so on, multimedia technology is more abundant in content, more intuitive in understanding, more vivid in expression, which can enhance students’ interest in learning and deepen the understanding of knowledge, which plays an obvious role in improving classroom teaching efficiency. Taking high school chemistry classroom teaching as an example, this article explores the role of multimedia technology in creating situations, analyzing mechanism, breaking through difficulties and optimizing experiments based on the author ’s years of high school chemistry teaching experience.
