The most common concern being expressed about the use of the iPad in schools is around keyboards and typing.  Can someone type on a flat glass screen effectively?

Absolutely.  Is it different than touch-typing on a standard keyboard?  Yes, but it can be done efficiently.

We have now visited or contacted several schools who have been using iPads for staff and students and they report that most people do not use external keyboards.  Every school we contacted had purchased keyboards expecting them to be heavily utilized, but that has not been the case.  In every instance, schools tell us that the majority of the keyboards remain on the shelf, waiting to be signed out.

An important consideration, regardless of typing on a notebook computer, or a tablet, is to create a workspace that is as ergonomically correct as possible.  Lay the device on a flat surface such as a table or desk.  Do not type with the device in your lap as this creates strain on your neck and shoulders.

If you are interested in learning more about the experiences of others who have already been using iPads with and without keyboards, here are links to a few studies and articles.
