Abstract
A call for the integration of research experiences into all biology curricula has been a major goal for educational reform efforts nationally. Course-based undergraduate research experiences (CUREs) have been the predominant method of accomplishing this, but their associated costs and complex design can limit their wide adoption. In 2020, the COVID-19 pandemic forced programs to identify unique ways to still provide authentic research experiences while students were virtual. We report here a complete guide for the successful implementation of a semester-long virtual CURE that uses Drosophila behavioral assays to explore the connection between pain and addiction with the use of an at-home "lab-in-a-box." Individual components were piloted across three semesters and launched as a 100-level introductory course with 19 students. We found that this course increased science identity and successfully improved key research competencies as per the Undergraduate Research Student Self-Assessment (URSSA) survey. This course is ideal for flipped classrooms ranging from introductory to upper-level biology/neuroscience courses and can be integrated directly into the lecture period without the need for building a new course. Given the low cost, recent comfort with virtual learning environments, and current proliferation of flipped classrooms following the 2020 pandemic, this curriculum could serve as an ideal project-based active-learning tool for equitably increasing access to authentic research experiences.Entities:

Means ± standard deviation were used for all survey instrument measurements, and P values were used for all comparisons. STETS refers to the science identity questionnaire developed by Stets et al. (23) in 2017 that measures science identity (SI), science identity prominence (SP), and science identity discrepancy (SD). RC indicates the research confidence questionnaire. URSSA is the Undergraduate Research Student Self-Assessment Measures developed by Weston and Laursen (24) in 2015 that measures thinking and working like a scientist, personal scientific gains, improvement of scientific skills, and improvement of researcher attitudes/behaviors. Pre refers to week 4 of the course prior to receiving the “lab-in-a-box”. Post refers to week 15 which was the end of the class.

FIG 1Science Identity Measures. This survey instrument assesses goal 1. (A and B) Science identity of full cohort at pre- and post-time points (A) and male versus female at pre- and post-time points (B). (C and D) Science identity discrepancy of full cohort (C) and male versus female at pre- and post-time points (D). Pre-time point assessments occurred during week 4 of the course prior to receiving the “lab-in-a-box,” while post- time point assessments occurred during week 15 at the end of the experimentation period. n = 12 for the full cohort (7 females, 5 males) with * indicating P < 0.05 and ** indicating P < 0.001 from paired and unpaired t tests.
