Abstract:Around the concept of information literacy, there are three types of description successively, such as defining, process and structural description, separately with views of Paul Zurkowski, Big6 and Sang Xin-min as typical representatives. In this period, people transform the point of view from the extension to the rich connotation, from focusing on the result of having the information literacy to the process of cultivating information literacy. From the technical development process, there are also three stages including keyboard interactive, GUI (graphical user interface) interactive and network application popularization. The goal description in the syllabus of each stage vividly reflects the technical background and the level of understanding at that time. We hold the opinion that the 2003 high school information technology curriculum standard is the intersection point of the ideas from the two clues mentioned above. It is the induction of understanding of information literacy.
