Abstract
In the paper, the cloud storage system on the Internet was used to distribute educational materials to students for improving students' self-study of structural mechanics. The students could contact the materials through various mobile devices; a smart phone, a tablet computer, etc. anytime and anywhere. We conducted a questionnaire survey to the students taking structural mechanics at National Institute of Technology, Oita College to consider the effect of the cloud system. Effectiveness of using the cloud system was clarified to produce educational benefits, especially improvement of self-study in reviewing for structural mechanics. Strategy was discussed to produce more benefits on the basis of some problems and future subjects found in the survey.
