Firstly I would like to agree wholeheartedly with Steve Draper's comments [7 Dec 98] on the Jones paper. Definitely "flow is the enemy of reflection" and "computer game playing is still a minority occupation" are good arguments against Jones proposition to incorporate game playing principles into computer based learning environments.
I would like to make one further point myself. I believe that the majority of computer games are simply about developing a level of skill at doing something that the game player did not possess already. Through repeated practice game players attempt to improve their performance (e.g., to complete the game). They are punished for incorrect behavior (e.g., they lose a life). They are rewarded for correct behavior (e.g., bonus points, extra lives, etc.). In other words, they undergo small increments of behavioral modification in learning how to beat the game. This being the case, surely Jones is not advocating a return to behaviorism in computer based learning environments? Surely this would be a step back rather than a step forward in the construction of learning environments?
