Setting Up an Online Lesson That Actually Works
Most wasted online lessons are lost to logistics, not teaching.
The difference between a good online lesson and a wasted one is usually decided before anyone starts teaching. This is the unglamorous checklist.
The setup that matters
A way to write by hand. The single biggest factor for maths and the sciences. A tablet with a stylus, or a cheap graphics tablet, or at minimum paper held to a second camera. A student typing algebra into a chat box is not doing maths, they are doing data entry.
A shared whiteboard, not a shared screen. Both people must be able to draw at the same time. If only the tutor can write, it is a lecture.
Headphones. They remove echo and, more usefully, they signal to the rest of the household that the student is unavailable.
A wired connection if possible. A dropped call in the middle of an explanation costs more than the minutes it takes to reconnect.
Camera on, both sides. A tutor needs to see a face to know when a student has stopped following.
The room
Not a bedroom, if it can be avoided, and not the kitchen table during dinner preparation. Hong Kong flats make this hard, and doing what you can still helps: a door, a surface large enough for paper and a device, and family who know not to walk through.
Phone in another room. Not face down on the desk. A phone within reach is a phone that gets checked, and every check costs more than the seconds it takes.
The five minutes before
This is where most of the value is created, and it costs nothing.
- Have the specific question ready. Not "I don't get moles" but "I don't get question 4b". A specific question gets a specific answer and saves fifteen minutes.
- Have the material open before the lesson starts, not after.
- Attempt the work first, badly. A wrong attempt is far more useful to a tutor than a blank page, because it shows where the reasoning broke.
During and after
The student should be writing for most of the hour. If the tutor is talking for fifty minutes of sixty, the lesson is going wrong regardless of how clear the explanations are.
Interrupt immediately when lost. Online, a tutor cannot see the small signals they would catch in a room, so the student has to say it. Getting a fourteen-year-old to do this takes a few weeks and is worth pushing for.
Afterwards: save the whiteboard, and redo one question from the lesson unaided within 48 hours. Understanding an explanation and being able to reproduce it are different things, and the gap between them appears about two days later.
