Evaluating Practical Methods in Secondary School Physics: Speed and Acceleration

This article reports on a workshop which examined practical methods used in Scottish physics classrooms to teach speed, velocity and acceleration in the National 5 certificated course. The data collected from the participants (n=5) consisted of field notes taken during testing and evaluation, and researcher summaries of discussions. Results indicate there is no option which could be considered the best or ideal equipment for all speed and acceleration practical work. However, there is a consistent view that practical work is essential when teaching these concepts and developing students’ understanding of the measurements and calculations made by electronic timing systems is crucial. Participants identified barriers to the implementation of experimental work as a reduction in technical support, equipment availability and quality, and budgetary concerns. Recommendations include gathering views from students and technicians, and data on the impact of practical work on academic performance.
