One more thing: state-of-the-art mania, that somehow was instilled in our brains. Yeah, like fancy computerized slide show is better than non-computerized. OK lets examine it - students looking at slides generated out of computer and it is somehow better than looking at the same slides generated manually by teachers - get it?
If your brain still says that state of the art equipment will improve student performance, please examine it. The only thing it will improve is - an extra figure in your school costs that parents (WHO ARE DEMANDING THIS NONSENSE!!!) will have to suffer through.
Please tell me if it was too harsh.
