Course -based undergraduate research experiences (CUREs) have been proposed as a mechanism to democratize access to the benefits of apprentice -style scientific research to a broader diversity of students, promoting inclusivity and increasing student success and retention. As we evaluate CUREs, it is essential to explore their effectiveness within the environments of regional comprehensive universities and community colleges, because they are important access points for a wide variety of students. It is also important to address the potential influence of volunteer bias, where students can opt to enroll in either the CURE or a traditional lab, on the outcomes of CUREs. We evaluated a CURE at a regional comprehensive university under conditions both with and without volunteer bias. We find that nonvolunteer students report a lower sense of discovery and relevance of the CURE compared with students who volunteered for the course. Importantly, we also find that our replacement of the traditional lab class with a CURE resulted in lower scores on exams in the associated lecture course among students who are both BIPOC and Pell eligible. We call for additional research on the effects of CUREs at nonresearch-intensive institutions and without volunteer bias, to better understand the impact of these classes.

The construction industry is rapidly changing due to the greater adoption of innovations and technology. This has necessitated changes in the competencies that the industry demands from new graduates. For academia to meet the changing needs of the industry, the inputs of practitioners are needed to complement academic pedagogical efforts. This study leverages the potential of Web 2.0 to develop a web platform called ConPEC to facilitate instructor-practitioner collaborations for enhancing student learning. ConPEC is aimed at providing instructors with equitable access to practitioners, increasing the participation of practitioners in instructors' pedagogical efforts, and enabling greater interaction of students with their communities of practice (CoP). These could facilitate achieving a proper blend of theory and practice in construction engineering education as well as ensure that students possess the competencies that the industry demands. This study demonstrates the efficacy of design principles in designing information systems. This study also demonstrates the usage of the Technology Acceptance Model (TAM) to explain and understand practitioners' acceptance of ConPEC. The findings reveal that practitioners perceived ConPEC to be useful, easy to use, and user-friendly. Practitioners' behavioral intention-to-use ConPEC is significantly influenced by attitude toward usage, perceived ease of use, and trust. Trust also significantly influenced perceived ease of use. However, perceived usefulness has no direct significant influence on practitioners' behavioral intention-to-use ConPEC. The study uncovers practitioners' acceptance behavior toward ConPEC which could be leveraged for further system development. The study also provides a framework that can be leveraged in diverse domains to develop similar initiatives aimed at addressing skill gaps in fresh graduates.
