One guy at my school had 'special considerations' for his exams last year.
Apparently his wrist was really sore or something so he couldn't write with a pen.
Anyway, he went on to get 50 for English and 48 for Philosophy, two subjects that really benefit from writing (typing) more. Apparently he wrote about 5000 words all up for his English exam.
There is no way to prove it, but you question how well he would have done if he hadn't had these special allowances.
Controversial.
Anyway,
Surely if the whole state did 'essay' subjects on computers, like English & Philo & Classics & Revs & Lit, and even subjects that just have short answer questions, such as Politics & Legal, then the general volume and standard of responses would be enhanced and I think this would be a good thing for all. As students, we can fit more into our responses and not worry so much about time. For exam markers, there is more to read and reward.
Doing these exams on computer would remove issues relating to illegible handwriting, and place more emphasis on writing ability and not just your hand's stamina. For these reasons I think there is a place for some subjects' exams to be done on computer.
Meanwhile, I think maths and chemistry are definitely still best suited to pen&paper exams. (Just try and do Short Answer #3a and #3d from this year's Unit 3 Chem exam using only your laptop! -
