This study tested what effect computer use by students had on reading and writing skills. Surprisingly student’s use of a computer during the school year improved their scores in the final test. That was despite it not involving a computer.
A more entertaining finding was buried in the middle. The researchers found that the use of Powerpoint to create presentations actually lowered the student’s marks in the final test. So Powerpoint is as bad for presenter as it is for the audience – something I had always suspected.
