“…Seymour and Hewitt (1997) pointed out the crucial role of motivational aspects in STEM retention, stating that losing interest and motivation to engage in STEM-related activities is the most common reason for students' decision to switch away from STEM majors. Although student gains and outcomes of undergraduate research (UR) experience have been well-discussed in the literature, systematic and empirical research to clarify the motivational factors, perceived drivers, and barriers of the processes of the research programs is limited (Adedokun, Bessenbacher, Parker, Kirkham, & Burgess, 2013;Cooper et al, 2019;Gardner, Forrester, Jeffrey, Ferzli, & Shea, 2015;Linnenbrink-Garcia et al, 2018). Mostly, evaluation and research studies regarding UR experience focus on reporting program outcomes with less emphasis have been put on exploring contextual factors (e.g., the design of the program and institutional features), sociocultural factors (e.g., socialization, mentor-student relationship), and participants' psychological factors (e.g., motivational beliefs) (Adedokun et al, 2013;Linnenbrink-Garcia et al, 2018).…”
