COVID-19 is here, and we’re all figuring out the new normal.
For many students, one consequence looms large: schools are closing, and they’re preparing to stay closed for months. The schools and the students alike are making the shift to distance learning. And they’re doing it right now, whether they’re ready or not.
But there’s more to it than just scheduling a video chat, or training for a day or two on Google Classroom.
We’ve been teaching the majority of our students via face-to-face video for years now. And not just from across the country. In fact, some of our students live less than a mile from our office. No kidding: the experience can be so seamless that even a five-minute walk seems wasteful.
It’s because we’ve practiced, year-round, for years. We’re happy to share our experience with you.
Here are some ideas for getting the most out of an educator who isn’t accustomed to working over video. They all come from years of trying everything, talking to everyone, and figuring it all out. It’s our pleasure to share it with you.
If you have more questions, schedule a chat. (Yes, we really are happy to help. No fee, no obligation.)
“Dr. Po-Shen Loh has discovered a new way to solve quadratics.”
Well, yes and no. Dr. Loh is a great coach, educator, and evangelist, and I admire and respect him. If he says he was “dumbfounded,” then there’s something there.
The thing is, though, that the press is making a big thing about the “new formula he’s discovered”. That’s just plain incorrect: the interesting part here isn’t the formula. That formula is just shoehorning a simple idea into the language of math, and in this instance the language is almost as cumbersome as with the original, better-known formula. So, not an improvement.
No, the key idea here is in putting together two facts:
- that the roots of a quadratic are equidistant from the centerline of its graph
- that that allows one to systematically work out the roots of a quadratic without either guessing or an explicit formula
Taught well, this new method will relieve students of the need to memorize any formula per se. Instead, students who understand this will follow the method intuitively, and will wonder why quadratics get so much careful attention in math texts: instead, they’ll just be obvious.
(Now that is a development worth writing about.)
