２１世纪的今天，教师必须建立起一种信息意识，并在所教的学科中渗透信息意识，使学生在潜移默化中逐步树立这种意识。从当前实际看，在物理教学中自觉地、充分地、恰到好处地运用自己设计或各类资源库中的优秀CAI课件，不仅有助于师生信息意识的增强、信息素养的提高，同时将 Today, in the 21st century, teachers must establish a sense of information and permeate information consciousness in the disciplines they teach, so that students can gradually establish this awareness in a subtle manner. From the current practical point of view, consciously, adequately, and properly using the excellent CAI courseware in its own design or various resource bases in physics teaching will not only help increase the information awareness of teachers and students, but also improve information literacy.
