“…In addition, according to the studies that have focused on inservice teachers, inservice teachers may not have the desired knowledge on environmental issues to teach it in their schools and/or may need further training in environmental education (Abramovich & Loria, 2015;Borg, Gericke, Höglund, & Bergman, 2014;Campbell, Medina-Jerez, Erdogan, & Zhang, 2010;Garcia & Cobar-Garcia, 2018;Okur-Berberoglu, Ozdilek, & Yalcin-Ozdilek, 2014). According to several studies, the main reason for the lack of enough knowledge on environmental issues to teach them in schools is the lack of environmental education or inadequate environmental education in preservice teacher training (Álvarez-García et al, 2015;Boon, 2010;Borhan & Ismail, 2011;Campigotto & Barrett, 2017;Demir & Avgın, 2016;Doğan, 2018). Yet, several studies have shown that when preservice and inservice teachers receive environmental education, they can improve their knowledge on environmental issues, have environmental awareness, and become environmentally literate (Álvarez-García et al, 2015;Anderson et al, 2013;Bertiz, Doğan, & Erten, 2017;Candan & Erten, 2015;Cebrián & Junyent, 2015;Dada et al, 2017;Fettahlıoğlu, 2018;Genc, 2015;Hamalosmanoğlu, Kızılay, & Kırmızıgül, 2020;Okur-Berberoglu et al, 2014;Putri, 2018).…”
