Primary Outcomes (end points)
The primary outcomes focus on beliefs, perceptions and behaviour. Constructs such as reflection and mindfulness, both measured using 4-item battery of questions in the form of likert scales. We gather information on altruism, fairness, reciprocity, and perception of teacher and student behaviour and that of inequality inside the classroom (Bottiani et al., 2016; Garcia Castro et al., 2020; Diehl et al., 2023; Falk et al., 2016; Falk et al., 2018). Behavioural dimensions such as pro-sociality, collective action and cheerfulness or patience in responding to questions are captured using direct questions or vignettes (Murphy et al., 2020; Alan et al., 2025; Diehl et al., 2023; Falk et al., 2016; Falk et al., 2018).
Alongside, we ask direct questions on school attractiveness and time preferences in the follow-up as a proxy for school climate and student’s psychological states.
