The purpose of this study is to develop rubric for evaluating students' scientific argumentation. Through analyzing the relevant literature related to argument in science education for developing rubric, the procedure in development and the category in evaluation for rubric were elicited. According to the general procedure in developing rubric, the standard for evaluating the argumentation was derived three categories such as a form, contents, and attitude. The category for a form was segmented into the sub-functions such as composition, claim, ground, and conclusion in the whole. The category for contents was segmented into the sub-functions such as understanding, credibility, and inference. And, the category for attitude was set to the sub-functions such as participatory level and openness. The standard for evaluating sub-functions in each of having been formed in this way was minutely suggested with 5 stages. The rubric, which was developed on the basis of literature, was inspected through a regular seminar in 1 expert in science education and fellow researchers. The rubric, which was developed in the early days, was again modified by being verified on problem and improvement matter after being entrusted to 4 experts in science education. And, the finally-completed rubric was indicated to be high with 0.96 in the content validity index by being verified the validity by 4 experts in science education. The developed rubric will lead to being able to increase the understanding about demonstration in students, and to being available for being utilized as the criteria for developing the argumentation process program and for evaluating the argumentation activity.
