Exploring Science Identity and Latent Factors of Student Gains in a Place-based Marine Science CURE Designed to Provide Access to Hawai'i Students from Historically Marginalized Ethnicities.

Hawai'i students, and in particular Native Hawaiian students, face high rates of attrition and low representation in Science, Technology, Engineering, and Mathematics (STEM) academic majors and careers, but place-based Course-based Undergraduate Research Experiences (CUREs) such as the Research Experiences in Marine Science (REMS) summer program may help to better engage these students with scientific content understanding and skills development. This article assesses latent factors of student gains after participating in the REMS program as they relate to student science identity. Results from an exploratory factor analysis examining the internal structure of an assessment measure delivered during the program suggest strong evidence of four latent factors in student self-reported learning gains: Content Understanding, Scientific Skills, Interest, and Integration. These factors will guide the development and delivery of the REMS survey as it is applied to additional cohorts of students participating in REMS and other, similar programs being developed and implemented in Hawai'i to support Native Hawaiian students. Although there were no significant relationships between these factors and responses to a science identity survey item, additional insights from an alumna of the program highlight how place-based elements in CUREs provide authentic and rigorous research training experiences for students from populations historically marginalized in STEM.
