euristics number @, A and B concern dialogues and error messages, none ofwhich exist in neither 2rodelica nor /penodelica, but that is why the

environment does not have a need for it' euristic number 45 concerns help anddocumentation' here is a help section on how to start using 2rodelica, whichwas appreciated by the users'

he evaluators also found that 2rodelica was less intimidating than otherprogramming environments, since the user is presented with an environmentsimilar to a document showing only a small amount of functionality' his leads theuser to believe that 2rodelica is a reading material' owever, after using the

material for a while the user discovers that 2rodelica could be used forprogramming as well'

" common approach adopted by many programming environments is to lead theuser in the opposite direction, by presenting all functionality from the beginning'his approach can have a discouraging effect on the user

2rodelica is a material intended to facilitate thelearning of odelica

2rodelica is based on Literate programming

he evaluation shows that Literate programming is a

suitable methodology for teaching odelica opefully 2rodelica will increase the usage ofodelica, and facilitate learning modeling and simulation
