More classrooms trying Khan Academy, finding it better than group projects

by Grace

Last week I criticized what I considered the hasty proclamation of a Khan Academy (KA) classroom pilot as a “colossal success”.  Nevertheless, because I am a big fan of Khan Academy and believe in its potential, I am happy to see this.

This semester, at least 36 schools nationwide are trying out Mr. Khan’s experiment: splitting up the work of teaching between man and machine, and combining teacher-led lessons with computer-based lectures and exercises.

The results so far make me feel cautiously optimistic.

It is too early to know whether the Khan Academy software makes a real difference in learning. A limited study with students in Oakland, Calif., this year found that children who had fallen behind in math caught up equally well if they used the software or were tutored in small groups. The research firm SRI International is working on an evaluation of the software in the classroom.

But look closely at what was happening in this class before KA.  Students would work in groups for days at a time trying to solve just one problem, an exercise that didn’t seem to help them master the fundamentals.

In the past, math class at the Summit schools was always hands-on: the class worked on a problem, usually in small groups, sometimes for days at a time. But getting an entire class of ninth graders to master the fundamentals of math was never easy. Without those, the higher-level conceptual exercises were impossible.

So what exactly were they really getting out of this teacher-supervised, time-consuming group work? This is a question many parents and mathematicians have been asking.

KA offers students a new, engaging way to learn the basics.  It also tracks data that provides teachers with precise individualized information on each student’s progress.  Good, because this allows teachers to do what they can do best.

Ms. Tavenner says she believes that computers cannot replace teachers. But the computer, she recognizes, can do some things a teacher cannot. It can offer personal feedback to a whole room of students as they work. And it can give the teacher additional class time to do more creative and customized teaching.

The thing is, I’m a little wary of giving teachers more time to oversee days of creative group projects with questionable learning goals.  I’d rather see teachers focus on taking advantage of Khan data to proactively address individual learning gaps, letting them be the expert humans interacting with and teaching students in ways no machine can.

  1. What Khan academy (and other similar programs) offers is a way to rethink education. Teacher’s unions want us all to believe the only way to fix education is to double down. Hire twice as many teachers (which is what must happen if class sizes are to hit their recommended sizes), pay them twice as much, and spend a small fortune rebuilding every school to have twice as many classrooms (which in many cases will require us to make them bigger too).

    Given our governments are already bankrupt this sort of thinking must be rejected. A new approach is needed. Khan Academy is just the beginning. We now have an affordable solution to improving education without having to double down with $ we don’t have.

  2. Steve, in theory KA and similar technology can lead to decreased teacher/student ratios while maintaining or improving achievement levels. Let’s see how this plays out; I foresee a bumpy ride as this disruption occurs.
