Hi, Terry, Well, I suppose I'll reluctantly have to agree. Even though the "practice as research" crowd has used this phrase in their advertisements for sugary, fizzy research PAR does have an older and better history. From Perth, where I have just returned from an evening of good conversation with Terry over a fine regional beer -- no Coke at all. Yours, Ken Terry Love wrote: I suggest it's perfectly appropriate for PhD students to use PAR to mean Participatory Action Research. Participatory Action Research is a well established research method, framework and philosophy. The PAR acronym has been used widely to denote Participatory Action Research for decades. In contrast 'Practice as research' is recent and challenged . Otherwise it's a bit like arguing that Engineers shouldn't use terms such as 'Energy' and 'Power' because Coke has used them in an advert!
