The effects of a short-term professional development program on physical education teachers’ behaviour and students’ engagement in learning

This study examined the effect of a short-term training programme οn in-service physical education teachers’ behaviour and students’ engagement in learning. Teachers (n = 32) were randomly divided into an experimental and a control group. Each teacher’s behaviour was observed in six lessons; two for each measurement (pre, post and retention) and analysed with qualitative dimensions of lesson introduction, task presentations and lesson closure. Student engagement was analysed with the time analysis form. The total and successful attempts of selected students were also recorded. The experimental group attended a two-hour lecture followed by a two-hour practicum, and showed significant improvement and learning of all the examined behaviours as well as significantly higher performance than the control group. Also, students of the experimental teacher group presented significantly greater activity time, more practice attempts and more successful ones than their peers in the control group. The results establish the effect of the training programme on teacher behaviour and student engagement in learning.     

Factors influencing students’ perceptions of graduate attribute acquisition in a multidisciplinary honours track in a Dutch university

This article studies the relationship between students’ perceptions of teaching and learning in a multidisciplinary honours programme and their impact on graduate attributes acquisition. The study, conducted among 73 honours students in a Dutch research university, evaluates perceived improvement in graduate attributes through annually collected survey data pertaining to student motivation, perception of the teaching and learning environment, engagement in the programme and registered course marks. The evaluation study reveals that to the extent of the perceived development of graduate attributes, three factors play crucial roles: students’ performance motivation, the amount of teacher support in creative and critical thinking, and students’ inclination to approach the honours track as a learning community.     

‘If there is a job description I don’t think I’ve read one’: a case study of programme leadership in a UK pre-1992 university

This paper reports on an exploratory study of the role of programme leaders (PLs) in a pre-1992 university, based on interviews with PLs (7) and a survey of taught Masters students (54) in a single school. The study elicits PLs’ activities, most of which might be categorised as managerial and administrative, with leadership required intermittently; the preeminent role involves managing programme quality. The study finds that institutional guidelines overlook important aspects of PLs’ work (such as organising enrichment activities and student advocacy) which affect the quality of provision, and the findings challenge the notion that PLs are engaged in a ‘disesteemed’ service.     

Inclusion Practices in Elementary Physical Education: A Social-cognitive Perspective

This study explored inclusion practices in general physical education (GPE) from the experiences and perspectives of elementary physical education teachers. The stories of four teachers (two females, two males) between 27 and 57 years of age were gathered using the phenomenological methods of semi-structured interviews, photographs, school documents, and field notes. Bandura’s social-cognitive theory provided a conceptual framework to interpret the findings of this inquiry. Three themes emerged from the thematic analysis: engaging in learning; adapting strategies to meet students’ needs; and moving beyond the educational goals. The findings suggest that inclusion practices (teacher’s behaviours) in GPE were constructed by the dynamic interactions between teachers’ knowledge of disability and motivation to learn about their students (personal factors) and children’s needs and learning goals (environment).
