Not so long ago, DPF posted about a fun way to learn calculus. Unfortunately, such things just don't work. The blood flows to all the wrong places. However, the principle is sound. A worthwhile teacher can spellbind an audience like any other performer. These teachers exist in NZ. For many of them, their skills are monopolised by the elite schools in the nice suburbs.
I wonder how much it would cost to get a film crew to record a year's worth of lessons from these excellent teachers? Sure, you'd pay the teachers a good salary, especially if you didn't want them to prostitute themselves to advertisers like sportspeople and former comedians do. Now, once you've taped the periods, you'll need to burn, print and distribute them to all eligible students. I can't be arsed checking for statistics so I'll make a bold generalisation. Let's say half of NZ's population gets sent lessons. At about $3 from burn to letterbox, that's $6 million to passively educate half of NZ. A percursor to this is already available in Oz, the Interactive Maths Series for Year 7-10 students. Even at $50 a year, it's cheaper than those voluntary annual school fees some of you will be coughing up for shortly.
Someone much smarter and more motivated than me has now done it. The Khan Academy currently features over 1800 YouTube videos covering a vast range of educational tutorials. Kim Hill talked to the founder Sal Khan this morning. Nice one, Sal!
