Rebecca Zook - Math Tutoring Online

When I started developing my online tutoring service, I thought that using a webcam would be an integral part. But I found tutoring via webcam strangely draining and brain-fragmenting. Turns out I prefer to tutor via phone! Here’s why:

Familiarity and ease of use. Most people are already used to talking on the phone.

We’re in sync. There’s no delay in transmitting voice over the phone, so it’s easy to stay in sync. However, at this point in the development of webcam technology, there is a slight microsecond delay between transmitting and receiving video data. This delay feels disconnecting and tiring.

It’s not distracting. It is easy to handle visual input from the computer screen while getting verbal input over the phone. But having the webcam in the same screen as the online whiteboard is weirdly visually distracting.

You know where to direct your attention. It’s easy to pick up on verbal cues over the phone and visual cues from the whiteboard. But when you’re using a webcam, you look in the same direction to see both the person in the webcam and the math in the whiteboard. There’s no visual way to tell which one you’re paying attention to. This is socially confusing.

Your attention is not fragmented. Toggling between multiple windows—for example, the online whiteboard window and the webcam video window—is a classic recipe for decreased focus and degraded executive function. Talking over the phone eliminates this problem, since you are only looking at one window: the whiteboard.

It is nice to put a face with a name, so I do offer new students the chance to start our very first meeting with an introduction via webcam. But then we turn the webcam off and just use the whiteboard and the phone for the actual working-on-math part.
