(i) The syllabus does not need to be "Linuxised", it just needs to be made product-neutral and OS-neutral, and task-oriented.
Yes, IT@School project made the syllabus for 9th standard based on this.
But selection of tool becomes an issue when text book is written and training for teachers is done.
(ii) Secondly, apart from just doing the above, it also needs to be reevaluated. Look at the crap they're being taught in schools in Goa!
Same in most places(including Kerala).
