多媒体技术服务于教学主要有以下优点:(1)将文字、图像、声音、动画有机结合,多种感官刺激,易于激发学生兴趣。(2)传输信息量大,传递速度可随机调节,以及操作的可重复性,易于学生对知识的接受。(3)交互性强,有益于学生主体地位的培养。正是基于此,在运用多媒体进行化学教学中,我做了以下几方面的探索与实践:
Multimedia technology services for teaching mainly have the following advantages: (1) The organic combination of text, images, sounds and animations, and various sensory stimulations are easy to stimulate students’ interest. (2) The amount of information transmitted is large, the transmission speed can be adjusted randomly, and the repeatability of operation is easy for students to accept knowledge. (3) Strong interactivity is conducive to the cultivation of student’s main status. It is based on this that in the use of multimedia for chemistry teaching, I have done the following aspects of exploration and practice:
