Unveiling Lasting Impact: A Cultural‐Historical Activity Theory Perspective on Original Participants in an Afterschool STEM Club

School Science and Mathematics, EarlyView.
ABSTRACT The Girls Excelling in Math and Science (GEMS) club is a long‐standing afterschool STEM program (1994–present). The study investigates the features of GEMS by exploring retrospective experiences of a group of original GEMS girls (OGGs) who attended GEMS in 1994–1995. Survey data were collected from 14 OGGs and in‐depth interview data from nine
