“…Cross-sectional and longitudinal analyses showed significant differences in pre-test as well as post-test NEP responses that varied by discipline of study and demographic factors, principally gender. In some studies, students held a weaker pro-ecological stance after completing regular courses (Harraway et al, 2012); other research revealed little or no changes in attitudes after sustainability education (Dagiliūtė and Liobikienė, 2015;Jowett et al, 2013;Mintz and Tal, 2013;Rideout, 2014;Yavetz et al, 2009); some reported a mixture of responses (Dagiliūtė and Niaura, 2014;Felgendreher and Löfgren, 2017;Fisher and McAdams, 2015;Sidiropoulos et al, 2013) while a few reported improved self-efficacy and self-reported behaviours (Mullenbach and Green, 2016;Sidiropoulos, 2014). More recent studies addressed several aspects of students' attitudes and behaviour, again with mixed results.…”
