The impact of video feedback on professional youth football coaches’ reflection and practice behaviour: a longitudinal investigation of behaviour change PartingtonMark CushionChristopher CopeEd HarveyStephen 2016 The aim of this study was to investigate the impact of video feedback on five English youth football coaches’ reflection and practice behaviours over a three-season period. First, quantitative data were collected using the Coach Analysis and Intervention System (CAIS) during season one and season three. Data from CAIS results showed that over the three seasons the coaches decreased their total instruction and total feedback and increased silence ‘on-task’. Four out of the five coaches also increased the use of total questioning behaviour. Second, interviews revealed how video feedback gave structure to reflective conversations that improved self-awareness and provided a trigger for behaviour change. The coaches highlighted how video-based reflection challenged their current understanding and enabled a range of learning sources to support and inform changed coach behaviour.
