现在多媒体教学已经是一种非常普遍的教学方式,与传统教学相比较,它具有的优势也是众所周知的。如改变了传统教学中粉笔加黑板的单一、呆板的表现形式,能将抽象、生涩、陌生的知识直观化、形象化,激发学生的学习兴趣,调动其主动学习的积极性。能使一些在普通条件下难以实现、观察到的过程形象化地显示出来等等。 Multimedia teaching is now a very popular teaching method. Compared with traditional teaching, its advantages are also well-known. If we change the single and inflexible expression form of the chalk and blackboard in traditional teaching, we can visualize and visualize the abstract, jerky and strange knowledge, inspire students’ interest in learning and mobilize their initiative in learning. It can visualize some processes that are difficult to realize and observe under ordinary conditions.
