the concept of peer assist is quite simple and it is more than just sharing good practice
experience and knowledge is gained in particular situation or context
knowledge is therefore context-dependent and doesn't always transfer easily to a different context
so,peers share their experience, both good and bad
then they take what is appropriate from all practice and develop a solution fit for the new context
having requested a peer assist, i share what i know based on the context in i which learn it
i don't force my best practice on others because the reality is i have not done it any other way so i can't possobly judge what is the best
