MFT spoke to math teacher Dave I. Ding to see how he uses PowerPoint presentations to teach math drills to his students. It's a pretty short interview because it's just so simple to use. MFT: So, Mr. Ding. I hear you've been using PowerPoint to create drill cards. Tell me more? Dave: Well, there's not much to tell, really. You just set PowerPoint onto automated presentation and it runs itself. Then you have some extra time for marking and lesson planning while students watch your presentation. MFT: Oh. So, what kind of presentations do you do? Dave: I like to use it for the good old multiplication tables, mostly. Sometimes I like to record myself reading them, because I have to admit to a great fondness for my own voice. I know some language arts teachers who like to use the automated presentation for teaching students to pronounce the vowels and other phonetics. It's really great. MFT: I see... Well, uh, is there anything else you have to say about it? Dave: Uhhhh... Not really... Nothing I can think of because well uh - ya - it's just so simple that I think I've explained it already.
