Have you ever sat through and silently suffered during a PowerPoint presentation?
Most likely, you have more than a few times. Together with ten other teachers, I have been asked (or is it told?) to do a PowerPoint presentation about my History elective subject for secondary level students at the international school where I teach, near Barcelona.
I will not do it.
The accepted "wisdom" is that in business (and therefore schools too, because money-makers know best) you use PowerPoint as automatically as you put on a suit and tie. It is generally taken as a given that "PP" is the best way to explain things to a group of people.
