Paired peer learning through engineering education outreach     

Laura Fogg-Rogers  Fay Lewis  Juliet Edmonds 《European Journal of Engineering Education》2017,42(1):75-90

ABSTRACT

Undergraduate education incorporating active learning and vicarious experience through education outreach presents a critical opportunity to influence future engineering teaching and practice capabilities. Engineering education outreach activities have been shown to have multiple benefits; increasing interest and engagement with science and engineering for school children, providing teachers with expert contributions to engineering subject knowledge, and developing professional generic skills for engineers such as communication and teamwork. This pilot intervention paired 10 pre-service teachers and 11 student engineers to enact engineering outreach in primary schools, reaching 269 children. A longitudinal mixed methods design was employed to measure change in attitudes and Education Outreach Self-Efficacy in student engineers; alongside attitudes, Teaching Engineering Self-Efficacy and Engineering Subject Knowledge Confidence in pre-service teachers. Highly significant improvements were noted in the pre-service teachers’ confidence and self-efficacy, while both the teachers and engineers qualitatively described benefits arising from the paired peer mentor model.  相似文献

I explain,therefore I learn: Improving students’ assessment literacy and deep learning by teaching     

《Studies in Educational Evaluation》2019

Partnership in higher education emphasises an active role for students in both teaching and learning. This pedagogical culture is likely to make students assessment literate and engage them in deep learning. In this study, Iranian students experiencing learning-by-teaching (LbT) in private language institutes were interviewed to compare their perceptions toward assessment and learning with their counterparts without this experience. Findings show that LbT fosters students’ assessment literacy and deep learning. Results also reveal that by teaching other students, quasi-teachers promote a broader understanding of assessment and grade practices in comparison to other students. Unlike their counterparts, quasi-teachers de-emphasised grades and showed a greater focus on learning. Moreover, explaining the materials to other students provided them with a deeper cognitive process resulting in deeper learning. These results underscore the perceived importance of partnership in higher education.  相似文献   

Activating the curriculum: a socio-ecological action research frame for health and physical education     

Justen O'Connor  Laura Alfrey 《Sport, Education and Society》2015,20(6):691-709

The health and physical education (HPE) profession needs to find alternatives to its individualistic and performative focus if it is to remain relevant and meaningful for all learners. This paper presents a way of framing HPE that helps to shift the focus from the individual as autonomous decision-maker, and goes beyond sport and fitness testing as the main contexts for learning. To do this we present the socio-ecological action research (SEAR) frame for unit development that was co-created and enacted over a six-month period involving dialogue between teachers, students, parents, researchers and community. This paper presents findings from semi-structured interviews, student artefacts and field notes collected as one component of a broader three-phase study which spanned three years. The data describe how generalist primary teachers (n=4) from a small Victorian community and their students (aged 8–10 years) tackled a unit of work that positioned centrally the everyday physical experiences of active school travel (AST). Teachers supported students in exploring barriers to their AST, and developing strategies that would counteract some of the negative perceptions that had limited their AST in the past. The findings suggest that the unit of work evolved from an exploration of AST into a much broader exploration of the whole community. This paper does not provide evidence for an alternative way to view HPE, rather it represents an embryonic exploration of how a SEAR frame might support teachers in applying inquiry-based pedagogies that extend beyond the individual as autonomous decision-maker, and promote opportunities for exploration and understanding of environmental, social and personal factors that influence our health and everyday physically active lives. Despite students being positioned as central actors within the SEAR frame, obtaining genuine student voice throughout the process proved challenging.  相似文献
