This paper explores the impact of learning problem solving tools such as Theory of Inventive Problem Solving (TRIZ) on self-efficacy. The paper utilises survey responses from 94 students who were enrolled in an RMIT-wide elective which taught students tools of TRIZ between 2006 and 2010. It was found that there were correlations between questions of self-efficacy and questions of attitude when facing future problems. A stronger correlation was observed between self-efficacy judged on enactive mastery experience (past performance) compared to self-efficacy judged on vicarious experience (peer comparison). Learning TRIZ was found to have a stronger influence on self-efficacy judged on past performance. The findings in this study suggest that learning specific tools of problem solving together with effective implementation can assist with the development of self-efficacy. Self-efficacy is vital as it impacts the willingness to face future problems which has a role in the improvement of problem solving ability. We propose that learning TRIZ leads to the development of problem solving skills. This paper is part of an ongoing PhD research that addresses the issue of the measure and transferability of innovative problem solving skills within the engineering field.
