时代在发展,教育在发展。在信息技术发展日新月异的今天,一种新的教学手段——多媒体便走进了我们的课堂。多媒体在教学中占有不可估量的优势,它改变了一支粉笔、一本书、一根教鞭的传统教学模式,实现了师——机——生之间的三者对话。它能化繁为简、化难为易、化静为动,把教师难以讲清、学生难于想象、难理解的知识一目了然地展现在学生面前。 The times are developing and education is developing. With the rapid development of information technology, a new teaching method, multimedia, has entered our classroom. Multimedia has an inestimable advantage in teaching. It changed the traditional teaching model of a chalk, a book, and a teacher, and realized a dialogue between the teacher, the machine, and the students. It can simplify everything, make it difficult to make things easy, and calm things down. It makes it hard for teachers to clarify and students’ hard to imagine and difficult to understand knowledge is presented to students in front of them.
