The Physiology Of Social-Emotional Learning: Integrating Biomarkers Of Self-Regulation Into The Assessment And Implementation Of Programs, Martin E. Blank

Master of Applied Positive Psychology (MAPP) Capstone Projects

In the last two decades, formalized social-emotional learning (SEL) programs in schools have proliferated in response to a staggering increase in mental, social, and emotional challenges for youth. SEL programs differ in their theoretical foundations, though there are commonalities among them. Self-regulation (SR) surfaces as an important pillar. Researchers have relied mostly on self-reporting and teacher questionnaires to measure the effectiveness of these programs to improve SR and other aspects of youth well-being, without explicitly considering the physiological effects of these interventions on the biomarkers of youth. By addressing this gap, program researchers, developers, and educators can reach their stated ...

The Assessment Of Swimming And Survival Skills: Is Your Programme Fit For Its Purpose?, Paolo Di Paola Aug 2019

The Assessment Of Swimming And Survival Skills: Is Your Programme Fit For Its Purpose?, Paolo Di Paola

International Journal of Aquatic Research and Education

Assessment of swimming and survival skills is a crucial part of any swimming and lifesaving programme. Unfortunately, quite often, it is also the weakest part of the programme itself. Inadequate skills assessment and verification might lead to ineffective skills acquisition and development, to a false sense of safety and over confidence in the water that can be extremely dangerous. Assessor experience and observation skills, assessment methodology, and criteria are all closely inter-linked and their interaction will somehow determine the assessment outcomes. Our paper analyses some of the current issues in these areas of the assessment process, such as assessor’s ...
