“…growing evidence supporting the importance of these early experiences, like tinkering with electronics and attending science camps, it remains unclear which ones are the most formative in terms of long-lasting impact on STEM career intentions (Dabney et al, 2012, Maltese, Melki, & Wiebke, 2014, National Research Council, 2009, Sahin, 2013. A large body of qualitative research has connected early informal experiences to science identity development (e.g., Barton et al, 2013;Maltese & Tai, 2010;Rahm & Moore, 2016;Zimmerman, 2012), which in turn has been found to be a robust lens for understanding why students make certain career choices (Carlone & Johnson, 2007;Godwin, Potvin, Hazari, & Lock, 2016). However, the relationship between early informal learning experiences, STEM identity, and STEM career intention is not well understood.…”
