“…Schauble & Bartlett, 1997;Falcão et al, 2004;Guichard, 1995), current research pertaining to the design of informal educational interventions such as science museum exhibits contributes mainly to an accumulation of general recommendations and design guidelines. Examples of such guidelines from the last three decades are the findings that computer-based exhibits engage visitors (Meisner et al, 2007), that partially completed exhibit puzzles are more motivating for children than fully completed or uncompleted puzzles (Henderlong & Paris, 1996), and that visitors are attracted by exhibits that impart a short clear message displayed in a vivid manner (Alt & Shaw, 1984). While these findings are no doubt both reliable and valid, the design principles derived from them are articulated at a level of generality which makes them difficult to refute, and can accordingly inform museum exhibit engineering only superficially (Moscardo, 1996).…”
