‘collaboration should be recognised as a state of social engagement that, on any given occasion, is more or less active and more or less effectively resourced. So, collaborators may vary in their concern to create shared understandings; and their circumstances of joint activity may vary in how readily they permit such achievements to be brought off. The challenge is to discover how discourse is mobilised in the service of creating joint reference; to see how what is created gets used as a platform for futher exploration; and to see how the material conditions of problem-solving can be more or less friendly towards efforts after this mutuality.’
