Compare test candidates using handwritten and electronic media. You'd need two groups, divided into two each, and cross reference the task. So one group would do a handwritten "email", another would complete the form sitting at a PC.
I'll need a sample of 250 overall. Important Exam Board may go for this, provide the sample and help me collect the data, because they are thinking, long term, of moving over to online testing.
I've got some experience with this, because the Mod 3 assignment was on asynchronous thread discourse and cohesion.
