This chapter reports on a project that seeks to improve regional and rural secondary school student participation in Science, Technology, Engineering, and Mathematics (STEM) by focusing on increasing student engagement and participation in these locations. These issues are addressed by academics employing a unique combination of evidence-based approaches. A collaborative co-design of a resource kit of STEM lesson plans (STEM Squad Kit) and other materials can be used by classroom teachers. The resource kit was designed by academics from the disciplines of Education, Information Technology and Engineering who all teach at a regional university in Victoria, Australia. A self-study method was adopted to enable the authors to reflectively examine their own pedagogies with the objective of improving their teaching approaches. Key findings include the importance of STEM curricula development being underpinned by a focus on learner engagement rather than content-driven curriculum design. Data findings indicated that greater resources in STEM were necessary to increase learner engagement alongside participation rates of girls and women in this domain.
