“…Furthermore, metacognitive skills are also considered to be good predictors of science achievement (Alpaslan, 2017;Areepattamannil, 2014;Kizilgunes, Tekkaya, & Sungur, 2009;Topçu & Yılmaz-Tüzün, 2009). Student-level motivational factors that have an effect on science achievement include but not limited to self-efficacy (Boz et al, 2016;Kalender & Berberoglu, 2009;Martin et al, 2012;Sun, Bradley, & Akers, 2012), self-concept, and perceived success (Abu-Hilal, Abdelfattah, Alshumrani, Abduljabbar, & Marsh, 2013;EARGED, 2009;Gevrek & Seiberlich, 2014; Jansen, Schroeders, & Lüdtke, 2014), enjoyment of science (EARGED, 2009;Martin et al, 2012;Ozel, Caglak, & Erdogan, 2013), and instrumental motivation to learn science (Abu-Hilal et al, 2013;Acar et al, 2015;Martin et al, 2012;OECD, 2016a;Ozel et al, 2013). On the other hand, teacher-level factors that have an effect on science achievement include student perception of instruction in terms of inquiry (Ceylan & Berberoglu, 2007;Kalender & Berberoglu, 2009;OECD, 2016b), teacher attendance to professional developmental programs (Atar, 2014;Milli E gitim Bakanlı gı, 2016;Shymansky, Wang, Annetta, Yore, & Everett, 2012), teacher support (Engin-Demir, 2009;OECD, 2016b;Sakız, 2015), and professional collaboration of teachers (Atar, 2014).…”
