Abstract
The roles and boundaries of school subjects have become blurred because of increased interest in generic skills. Owing to this situation, concern regarding the integration of social studies and literacy has increased in the United States. The aim of this study is to clarify the methods of integrating literacy into social studies through an investigation of approaches in the United States. This study reveals the following three types of approach: 1) educational content-based approach; 2) educational method-based approach; and 3) educational aim-based approach. As a result of comparative analysis, this study posits that the degree of emphasis on the framework of social studies and the level of developing the ability to effectively get involved with society will become increasingly higher from the first to the third type of approach.
