Trainee teachers’ experience of primary science teaching,and the perceived impact on their developing professional identity

This study took place within an environment of educational change in teaching and assessment in the UK, where the National Curriculum (NC) and National External Examination syllabi undertook significant revision. Science education specifically, has seen aspiration raised to allow pupils to achieve a greater depth of understanding at Key Stage 4 and hence facilitate advanced study. Central to the development of effective scientific understanding is teacher preparation. This study examined the factors that impacted on the experiences of primary teachers during their training. Questionnaires completed by a sample of one hundred and sixteen trainee teachers followed by semi-structured interviews of sixteen trainees were used as a means of interpreting Post-Graduate Certification in Education (PGCE) trainee teachers’ experiences during taught university sessions and school based training. The findings showed that the majority of the trainees rated their training highly, and perceived themselves to be confident primary science pedagogues. They felt, however that the very limited opportunities to observe and teach science during their training negatively influenced their overall development.     

Muscle activity in sprinting: a review

The use of electromyography (EMG) is widely recognised as a valuable tool for enhancing the understanding of performance drivers and potential injury risk in sprinting. The timings of muscle activations relative to running gait cycle phases and the technology used to obtain muscle activation data during sprinting are of particular interest to scientists and coaches. This review examined the main muscles being analysed by surface EMG (sEMG), their activations and timing, and the technologies used to gather sEMG during sprinting. Electronic databases were searched using ‘Electromyography’ OR ‘EMG’ AND ‘running’ OR ‘sprinting’. Based on inclusion criteria, 18 articles were selected for review. While sEMG is widely used in biomechanics, relatively few studies have used sEMG in sprinting due to system constraints. The results demonstrated a focus on the leg muscles, with over 70% of the muscles analysed in the upper leg. This is consistent with the use of tethered and data logging EMG systems and many sprints being performed on treadmills. Through the recent advances in wireless EMG technology, an increase in the studies on high velocity movements such as sprinting is expected and this should allow practitioners to perform the analysis in an ecologically valid environment.
