“…When the studies in the literature are examined, analysis studies on the biometric analysis of scientific research on STEM (Özkaya, 2019), meta synthesis (Herdem & Ünal, 2018), content analysis (Aydın-Günbatar & Tabar, 2019;Çevik, 2017;Kaleci & Korkmaz, 2018), review (Jayarajah, Saat, Rauf & Amnah, 2014;Tezel & Yaman, 2017;Yılmaz, Gülgün, Çetinkaya & Doğanay, 2018), analysis of qualitative findings (Kanadlı, 2019) and methodological analysis of STEM studies (Özcan & Karabaş, 2019) were carried out. Furthermore, analysis/ meta-analysis of STEM-related experimental studies (Belland, Walker, Kim & Lefler, 2017;van den Hurk, meelissen & van Langen, 2019;, metaanalysis of the impact of STEM on cognitive outcomes (Belland, Walker, Olsen & Leary, 2015) and meta-analysis of STEM-related studies (Kim, Belland & Walker, 2018) were conducted.…”
