The purposes of this study were to develop an instrument to measure high school students` systems thinking and 10 validate the scale. The scale of systems thinking was made up for 5 factors - systems thinking, mental model, shared vision, personal mastery, and team learning through analyses of related literature. Six items per factor were constructed and the scale consisted of a total of 30 items for the pretest. After exploratory factor analysis, the number of totaJ items was reduced to 20 items. For the main test, 280 students were sampled from high school and analyzed valid cases were 260 students. The finding of the exploratory factor analysis indicated 5 factors in the model, and 4 items per single factor. The result of confirmatory factor analysis was generally appropriate and acceptable (5 factor model: x2/df=1.275, TLI=.946, CFI=.959, RMSEA=.033). The reliability for 20 items turned out to be reliable because the Cronbach`s alphas were .840 and .604-.723 per each factor. This study should be expanded to various school levels and should be standardized for further research. The subsequent studies regarding diverse leari1ing program development and implementation and the verification on the students` impact within the developed program can be recommended.
