“…In this regard, it can be argued that the significant change in preschool teachers' perceptions about early STEM education from pre to post-test in this study is parallel with the findings of the study by Alade, Lauricella, Beaudoin-Ryan and Wartelle (2016), Aldemir and Kermani (2017), Bers, Seddighin and Sullivan (2013), Dejonckheere, Wit, Keere and Vervaet (2016), Kermani and Aldemir (2015), and Master, Cheryan and Meltzoff (2017). The results of the studies about the effects of STEM workshops on secondary school teachers' beliefs, knowledge or practice are also in line with the findings of this study (Gardner, Glassmeyer & Worthy, 2019;Altuger-Genc, & Issapour, 2015;Çavaş, Yar, Bula Turuplu, & Gürcan, 2019;Yıldırım, 2020) Another comparison can be made with the qualitative studies that reveal the positive change in the scope of participant teachers' perceptions (Bozkurt Altan & Ercan, 2016;Doğan & Saraçoğlu, 2019;Özbilen, 2018;Yıldırım 2018;Ring, Dare, Crotty & Roehrig, 2017). The contribution of this study is that it provides the opportunity to articulate the significance in numbers.…”
