The chapter clarifies how a transactional approach, by providing a specific view of the relationship between bodies and environments, can inform movement learning analysis. By emphasising classical pragmatism’s central ideas of experience (radical empiricism) and learning (the process of inquiry) two transactional principles are identified and then discussed in relation to empirical research. Methodological challenges, such as how to deal with the individual and social as simultaneous and mutual, and how to handle learning as practical and embodied, are described through previous empirical research. In doing so, the chapter explains how movement have been explored in term of what stands fast for participants in movement, which gaps they experience when they move, and what it means to create relations between old and new experiences. Using concepts of stand fast, gap, and relation transactional informed empirical research has gained detailed descriptions of, for example, how pupils navigate spatial-temporal conditions through movement, establish and maintain habits, achieve stability in terms of cooperation, use aesthetic judgements to make sense of movement, accept or refrain from intergenerational touch and gain balance and manoeuvrability in dinghy sailing. Transactional models used in research can, furthermore, be used by practitioners in order to observe, understand and discuss ongoing movement learning in their own or others’ practices. For example, help learners to identify certain gaps, privilege specific standing fast moments and recognize when and which relations fulfil certain purposes.
