It has been clearly s hown in the comparison of a group with experience of a lesson of “making things”to a group without the experience that the lesson is highly effective in the progress of self-efficacy in the fields of the accumulation of information, the perspective in the future life and the evaluation of self ability. The relation between the progress of self-efficacy and the career formation has been also discussed.
