多媒体技术已经逐步进入了课堂。传统化学教学中的教学媒体如实物、模型、挂图、实验等,虽然形象、直观,但有一定的局限性,多媒体技术在初中化学课堂教学中以声、形、视听等手段,能最大限度地、生动形象地、形象逼真地进行模拟,多方位刺激学生的感官,不仅有利于知识的获取,而且有利于知识的保持。同时能激发学生的学习兴趣,增大课堂容量,优化教学过程,提高教学质量。 Multimedia technology has gradually entered the classroom. The teaching media in the traditional chemistry teaching such as the real object, the model, the flip chart, the experiment and so on, though the image and the intuition have some limitations. The multimedia technology can make the most of the medium, , Vividly, vividly simulate, multi-faceted to stimulate the senses of students, not only conducive to access to knowledge, but also conducive to the maintenance of knowledge. At the same time can stimulate student interest in learning, increase classroom capacity, optimize the teaching process, improve teaching quality.
