and analyze the spatial data easily. But it is difficult to use by non-specialists without education or tutorial. Sediment Assessment Tool for Effective Erosion Control SATEEC) was developed to provide easy-to-use GIS interface to estimate soli erosion and sediment yield at watershed-scale. However, it is also difficult to use for beginners. Therefore, audio-visual manual was developed and its learning effects were analyzed in this study. To investigate this research, survey were conducted from Kangwon University including 34 students. The questionnaire was composed of 15 items about general effects when using manual and 5 items about visual education effect. As a result, group of educated using visual tools showed higher ability in performance and learning satisfaction. It shows that the audio-visual tools are effective for learning GIS based tools. Therefore. use of audio-visual learning materials in GIS environmental issues are highly recommended.
