Research studies have shown that educational programmes such as camps and field trips can develop affective and social relationships through personal exposure to outdoor experiences among students. This study will illustrate the outcome of a social emotional learning camp organized for 93 Secondary Two students (mean age 14.1) in Singapore. Both quantitative and qualitative methods were carried out during camp to assess students' social emotional competencies (SECs) such as their self-awareness, social awareness, self-management and relationship management and responsible decision-making. Students were found to have improved in all SECs from the pre-post test questionnaire. From their camp activities and their reflections, students were found to have greater self-awareness, relationship management and self-management skills. However, teachers' observations showed that students scored lowest in relationship management skills. Students' self-awareness, social awareness, self-management and relationship management were found to be predictive of responsible decision-making, with 71% of the variance explained. The implications of the findings will be discussed to assist schools in enhancing students' SECs.
