Abstract
In this paper, we describe the results of content analysis for the textbooks about "Information" in high school education. Based on these results, we try to clarify the description tendency common to these textbooks, and to detect each characteristic of them. About information A, chapters for the problem solving came to be described concretely and in detail. Additionally, descriptions to promote the independent-minded stance to utilize information increased. About information B, as for the descriptions about a function and structure of a computer, they were selected carefully. Some chapters about information technology in society were regarded as more and more important. About information C, the textbook authors' described extensively on issues related to the structure of an information communication network and the network communication.
