In a recent podcast episode with Michael Shermer, Chris Edwards, a teacher and author, points out that online resources can take the place of many in-class presentations. He’s obviously right about that, but he’s not too specific (at least here) about what future role he sees for classrooms and teachers. My sense is that teachers should use classroom time for things obviously done better in groups, such as certain sorts of science projects. I think that classroom math instruction often is useless but that one-on-one tutoring always will be helpful, especially for students falling behind or with special needs. I suppose that certain sorts of math lessons are especially amenable to a group setting. (Interestingly, at this moment, my six-year-old is watching newly released Generation Genius videos on K–2 math, which are quite good.)
Edwards also points to the obvious truth that measuring educational results by time that students spend in seats is absurd. What matters is mastery. My own sense is that students waste an enormous amount of time in classrooms. I think that, especially in younger grades, students should spend limited time in deep concentration learning the traditional subjects and spend the rest of the day playing and working on their own projects. That’s basically the approach I take in homeschooling.
I found Edwards’s remarks thought-provoking; it’s a long discussion, but some people will be interested in the entire exchange.
