The purpose of this study was to investigate the effects of self-instruction strategy on the task completion of tangram education program performed by students with multi-handicapped blind. For the purpose, the research design of miltiple probe baseline across subjects was used and task completion rates were measured. The subjects were 3 males elementary syudents in twenties. Also the tangram education program was conducted for students with multi-handicapped blind 43 sessions, four times a week. The maintenance was carried out five times after the experiment stopped.
The findings of this study were as follows.
First, self-instruction strategy was effective on improving the task completion of tangram education performed by multi-handicapped blind students during the period of intervention. As the intervention sessions went on, their task completion rates of tangram education program were increased than those during the baseline sessions, the needed time for task completion was decreased, and the needed time for self-correction at the trial and error was decreased. Also increasing their task completion rates, experiences of failure were diminished and experiences of achievement were grown.
Second, the task completion improved by use of self-instruction strategy was maintained even after the intervention stopped. The task completion rates by the use of self-instruction strategy lasted.
There were at least four limitations of this study. First, this study results cannot be generalized to a most of elementary syudents. Second, this study results cannot be generalized to students or adults who are twenties by the chronological age. Third, this study results cannot be generalized to students with different categories of disabilites. Fourth, this study results cannot be generalized to females.
There are some suggestions about more successful approach to self-instruction strategy and edcation for blind students. First, the tangram education program were applied with in this study, but in the future the effect of the self-instruction strategy should be examined more precisely by including more diverse education programs, gender and schools levels.
Second, follow-up studies should be worked hard th developing a variety of effective intervention method or authentic educational materials so as to utilize and improve the students' visual function with remained sight.
