A survey of 582 first-year engineering students at a STEM institution yielded quantitative results. Then, to explore the initial results in more depth, a follow-up study using two separate focus groups was completed with purposefully selected respondents. The follow-up qualitative phase attempted to provide logical connections to the findings from the original quantitative phase, which showed that students who live within RLCs have experiences that provide those students with opportunities for MIRs. In the quantitative phase, statistically significant results were limited to a difference by gender. The quantitative and qualitative findings from the two phases of the study are discussed, with reference to prior research. Implications and recommendations are provided.born digitaldoctoral dissertationsengCopyright and other restrictions may apply. User is responsible for compliance with all applicable laws.
