In the dim and distance past I remember several styles of teaching:
1) Stand at the front and speak, no visual aids or hand outs - generally terrible as you can't write as fast as they can speak. Sometimes brilliant but that's rare.
2) Repeating what your slides/overheads said. Again you can't keep up and anyway there is evidence you don't remember well if you have the same visual and audio input.
3) Handouts with some detail on and you have to full out the blanks and scribble round. You then listen to what is said and annotate your hand outs - GOOD, always my favourite as you get the detail and human interaction without having to worry about keeping up.
4) Complete handouts - why bother with the lecturer?
5) Dictated notes, not much difference from 4 except you have to write them yourself.
Creating good presentations and lectures requires skill as it involves multiple skills but I'd say that PowerPoint is probably the least useful of skills in the mix. So the article probably has some truth to it.
