[quoting Hart, 25 Jul 96] It has been the tragedy of educational technology that so much fruitless effort has been spent over the past 50 years to try and prove that media affect (improve?) learning. Only content affects learning--the medium is, as Clark says, no more significant than the truck that delivers our food.
This is entirely true! It is not the media that improves learning but the content. However, media enhances the organization of the content. Or, rather many times, the media buries the content in either fog or glitz. Concentrate on not what is the better of the two, content or delivery, but on the melding of both.
