This study is trying to analyze characteristics of mathematical thinking processes of the mathematical gifted students in an objective and a systematic way, by using "Protocol Analysis Method"and "Problem Behavior Graph" which is suggested by Newell and Simon as a qualitative analysis. In this study, four middle school students with high achievement in math were selected as subjects-two students for mathematical gifted group and the other two for control group also with high scores in math. The thinking characteristics of the four subjects, shown in the course of solving problems, were elicited, analyzed and compared, through the use of the creative test questionnaires which were supposed to clearly reveal the characteristics of mathematical gifted students' thinking processes. The results showed that there were several differences between the two groups-the mathematical gifted student group and their control group in their mathematical talents. From these case studies, we could say that it is significant to find out the characteristics of mathematical thinking processes of the mathematical gifted students in a more scientific way, in the sense that this result can be very useful to provide them with the chances to get more proper education by making clear the nature of thinking processes of the mathematical gifted students.

본 연구는 교사가 교육용 웹사이트에서 교육 자료를 검색할 때의 인지과정을 탐색해 보고 교사가 어떠한 부분에서 인지적 어려움을 겪는지 분석하고자 하였다. 이를 위해 세 명의 교사에게 교육 자료를 검색하는 세 가지 과제를 준 후, 과제 수행 시의 인지과정을 PBG 그래프(Problem Behavior Graph)를 활용하여 분석하였다. 분석결과를 바탕으로 교육용 웹사이트의 사용성 향상을 위한 개선 방안을 제안하였다.
