This paper presents a study which aims to provide an understanding of the impact of using the components of a digital mobile-based behavior change intervention (mBCI) to support critical thinking skills during university student research projects. The digital behavior change interventions are tools and techniques designed to induce behavior change and provide continuous support and tailored advice for willing learners through web and mobile platforms. We investigated the impact and the usability of the designed tools by analyzing self-reflections and the users on the digital mobile-based behavior change intervention components. An instrument was used to examine the differences in the self-perceived improvement of critical thinking between the intervention group and the control group before and after working on real research projects for two months. The results of comparing post surveys for the independent samples showed that the intervention group had a statistically significant perceived improvement in critical thinking than the control group. The findings indicated encouraging and positive feedback on the use of mobile intervention components to promote critical thinking when supervising research projects.[For the complete proceedings, see ED601100.]
