The most useful explanation format is the one that lets you repeat the method on a new question by yourself. Test formats against that, not against how comfortable they feel.
This page compares four common formats using one original IGCSE example, then gives you a way to choose and to ask.
What formats are there?
Online lessons usually use some mix of these.
| Format | How it works | Helps when |
|---|---|---|
| Spoken | The teacher talks through each step | You follow reasoning well by ear |
| Typed steps | Each step appears as a short line of text | You need time to reread |
| Handwritten working | The teacher writes and you see it form | You want to watch the layout of a method |
| Worked example, then your turn | You see a full solution, then attempt a similar one | You learn by copying, then adapting |
Nobody needs only one. A mix is common, and what works can change between topics.
Worked example: one question, three formats
Question: Solve 2x + 5 = 17.
Spoken version. “We want x alone. First undo the plus 5 by subtracting 5 from both sides. Then undo the times 2 by dividing by 2.”
Typed-steps version.
- 2x + 5 = 17
- 2x = 12 (subtract 5 from both sides)
- x = 6 (divide both sides by 2)
- Check: 2 × 6 + 5 = 17
Worked-then-your-turn version. The teacher shows the typed steps above, then sets: Solve 3x + 4 = 19. You attempt it.
The answer is x = 5, since 3x = 15 and 15 ÷ 3 = 5. Check: 3 × 5 + 4 = 19.
All three contain the same maths. The difference is what you can do afterwards. Which one let you solve the second equation without looking back?
A plausible mistake
A student says, “I understood it while the teacher was talking,” but freezes on the next question. Understanding while listening and being able to reproduce are different. The correction is to add a step where you attempt a similar question straight away, in whatever format you choose.
How do you choose?
Try this quick routine in a lesson or on your own.
- Take one short question you can already solve.
- Ask for it in format A, then in format B.
- After each, close the notes and solve a new question of the same kind.
- Keep the format that produced the correct second answer with less hesitation.
Repeat with a harder topic, because the answer may change.
What can you ask the teacher?
Short, specific requests are easiest to act on.
- “Please type each step as you say it.”
- “Can you pause after each line so I can copy it?”
- “Can I attempt the next one before you show the method?”
- “Can you keep the screen still while I read?”
You do not need to explain why. You are telling the teacher what helps the lesson run.
Self-check
1. You watched a full solution and felt confident, but could not start the next question. What should you change?
Show answer
Add an immediate attempt on a similar question, so the format includes practice and not only watching.2. Solve 4x − 3 = 13, and say which step you would type.
Show answer
4x = 16 (add 3 to both sides), so x = 4 (divide by 4). Check: 4 × 4 − 3 = 13.When may one-to-one tuition be worth considering?
Comparing formats on your own is often enough for a small gap. A one-to-one lesson adds something when you cannot tell which part of an explanation is losing you, because a teacher can change the format on the spot and watch what happens.
Start with the online lesson readiness check to choose your writing method. Read keyboard and reduced-motion controls for set-up, and enquiring with accessibility requirements when you are ready to ask.
