In this second article on the theory of "ground rules for talk" I extend a debate between myself and Professor Neil Mercer over the introduction of "ground rules" into classrooms. I critique ground rules through the use of sociological theory and argue that advocates of the ground rules perspective need to recognise the ideological nature of their theoretical position. In making this article a clear extension of my previous argument I introduce the work of Bernstein and Fairclough to support my new arguments. I use Bernstein's theory of pedagogy as cultural relay and Fairclough's appropriateness model of language variation to critique "ground rules perspectives". In doing so, I draw out the political nature of educational theory and curriculum within the context of a specific socio-economic society.
