“…Hicks [14] indicated that learning about global issues such as sustainability and acting upon it can never be solely a cognitive matter, but must also involve an affective understanding. Nonetheless, increasing knowledge may not automatically result in changes in awareness and actions [15], so educational institutions aim at development of deeper circular learning patterns, where the knowledge is reflected upon and questioned in learning loops before application [12,[16][17][18] Several studies have focused on students' perceptions of sustainability [19][20][21], the impact of the amount and type of coursework on students' conceptualizations of sustainability [22], and the relationships of demographic factors on students' environmental awareness, knowledge and behavior [23,24].
