A ‘Blank-chart technique’ is one of problem solving techniques for management consultants, which may be applied for students in order to promote problem solving process and skills in learner centered teaching and learning environments. Furthermore, a blank-chart leads to draw visual images of final outputs before students propose outcomes. In this study, students who had been instructed in a ‘Blank-cart technique’and applied it to develop team projects. This study examined the outcomes of a ‘Blank-chart technique’ in team projects; and, in particular, we analyzed the opinions of participants of this study regarding the difficulties in performing team projects and the usefulness of applying a ‘Blank-chart technique’ to conduct their team projects. Main difficulties in performing team projects were a) making concrete plans and setting up time tables, b) allocating tasks/roles to team members, c) developing and finalizing the outcomes of their team project, and d) communicating each other sufficiently. In regard to overcoming these difficulties, it was finding that Blank chart technique had usefulness and advantages in a) developing diverse contents and ideas, b) establishing a systematic and concrete pan of what to do, c) facilitating communication among team members and developing communication skills. The research outcomes supported that ‘Blank-chart technique’ was effective in improving outcomes in team-based learning and activities.
