It is no wonder that the educational evaluation plays an important role in the whole educational process. That is, the educational evaluation not only judges whether students attain educational goals, but also has an important effect upon the instruction-learning process. Therefore, it is necessary to develop tool of the social studies evaluation for the development of the social studies education. The purpose of this study is to develop performance assessment tool which is emphasized recently in the field of the social studies education. Learning area which I select to develop performance assessment tool which is emphasized recently in the field of the economic education is market failure and role of government. Examples of performance assessment tool which I develop are portfolio about market failure and role of government, research report which is based in questionnaire analysis, making newspaper, analysis of TV monitoring, and interview. I suggest that teachers in economic education try to develop performance assessment tool to utilize in the field of the social studies education, because teachers are able to meet students in instruction-learning process.
