A teacher moving to video loses the thing that made them good in a classroom: the ability to see a face not understanding and change course. Everything below is a way of compensating for that.
The teachers who do well on short video are rarely the most knowledgeable. They are the ones who narrowed hardest.
One concept, not one lesson
Structure that works without a classroom
- Open with the question a student would actually ask, in their words — not the textbook heading.
- Give the answer in one sentence before explaining it.
- Work one example on screen, at the speed you would write it.
- Name the mistake most students make on this exact point.
- Stop. Do not add the related thing you also know.
Show the working
Explaining a method is far less useful than working a problem while talking through it. A student watching a worked example gets the pacing, the order of operations and the small decisions that an explanation skips over.
It is also easier to film, because you already do it. Point a phone at what you would write on a board anyway.
| Format | Why it works | Effort |
|---|---|---|
| A worked example | Shows the doing, not the theory | None — film what you write |
| The common mistake | Every teacher knows five of these | None |
| One concept explained | Findable by search | Low |
| Exam question breakdown | Directly useful in season | Low |
| Answer-writing technique | Rarely taught, changes marks | Low |
| Revision in ten minutes | Shared between students | Medium |
Students' privacy
- Written parental permission for any student's face, name, marks or work.
- Never combine a name with a result. Any two of face, name and marks is already more than most parents expect.
- Do not film a class without the school's and parents' agreement.
- Prefer the board and your own hands. It works as well and asks nothing of anyone.
- Take anything down the same day if a parent asks.
Time it to the exam calendar
Study content has the most predictable demand curve of any category. Interest climbs steadily toward board exams and collapses immediately after, and the same cycle repeats every year.
So build the syllabus content in the quiet months and post it as the season builds. During the exams themselves, switch to short, calming, practical material — revision, answer-writing, what to do the night before — because that is what a stressed student can actually use.
The short version
- One concept per video. Six short beats one long.
- Open with the student's question, not the textbook heading.
- Work the example on screen. It is more useful and easier to film.
- The mistake most students make is content you already have.
- Written parental permission for any face, name, marks or work.
- Build in the quiet months; post as the exam season builds.
