Back in 1983, Dick famously wrote, “Consistent evidence is found for the generalization that there are no learning benefits to be gained from employing any specific medium to deliver instruction.”
And, “The best current evidence is that media are mere vehicles that deliver instruction but do not
influence student achievement any more than the truck that delivers our groceries causes changes in our nutrition.”
Happy Birthday, Dick!
And thank you for all of your contributions to L&D!
