Well, in Norway this has been turned around. GRAVA will proberly be used as well, but the main foucus is to get the industry (book publishers) to make SCORM-packages, so that they can be used to complement books, or to replace books. But that is almost war, bcause the publisers want to make money on it, and they feel that it can be a lot like the music-industry were there is a big problem with piracy.
Cuz the focus is that teachers shall teach, not be authors. Today they are using to much time on authoring materials, and this takes away their main focus: TEACHING :-)
But by all means, GRAVA is one way to go, hopfully to get publisers make these SCORM-packages. But GRAVA will not solve the problem where teachers use their time on everything else (but I know a lot of techers are looking forward for this tool :-)
Litle off-track there, but GRAVA is a lot like x-files, you don't belive it, unitil you see it ;-)
