... There are some systematic reviews and meta-analyses that reveal common patterns in the results of these studies with secondary data, like the relevance of socioeconomic and contextual factors (Banerjee, 2016;Hopfenbeck et al., 2018), or the importance of process factors, both at student levelpositive attitudes towards school and learning (Banerjee, 2016) and at school levelteacher expectations and implication, adaptation of instruction or educational leadership (Drent, Meelissen, & van del Kleij, 2013).

More consistent results are found in other questions such as classroom coexistence and climate (Choi & Calero, 2013;Guo et al., 2018;Mikk, Krips, Säälik, & Kalk, 2016), use of ICT (Petko, Cantieni, & Prasse, 2017;Skryabin et al., 2015;Tan & Hew, 2017;Zhang & Liu, 2016), educational leadeship (Gil-Flores & García-Gómez, 2017;Guo et al., 2018) and staff teaching and job satisfaction (Marcenaro-Gutierrez, Luque, & Lopez-Agudo, 2016). ...
