Here’s a quiet truth in Computer Science classrooms:
Teachers are brilliant debuggers.
And that’s the problem.
Because every time you fix a student’s error for them, you steal the exact skill the subject is trying to build.
You don’t mean to.
You’re being helpful. Efficient. Kind.
But coding is not learned from kindness.
It’s learned from confusion, frustration, and the slow, painful joy of figuring out why it’s not working.
What usually happens
A student says:
“Miss, it’s not working.”
You walk over.
You look once.
You see the missing colon, the wrong variable name, the indentation, the bracket.
You point.
They fix it.
They smile.
You feel productive.
They learned nothing.
What should happen
A student says:
“Miss, it’s not working.”
You say:
“Good.”
And you walk away.
Not because you don’t care.
Because this is the lesson.
Debugging is the subject
Writing code is not the hard part.
Fixing code is.
And if students never get used to sitting with broken code, they never become independent.
They become dependent on the teacher’s eyes.
Which means in an exam… or real life…
They are stuck.
Because you’re not there to say:
“Line 7.”
The uncomfortable bit teachers avoid
Silence.
Watching a student stare at the screen for 4 minutes doing nothing.
That’s the moment most teachers jump in.
But that 4 minutes is where the brain is doing the heavy lifting:
- Re-reading
- Checking logic
- Comparing lines
- Thinking, not copying
That’s computational thinking forming in real time.
Funny but true examples
You’ll see things like:
They will read it 12 times and not see it.
Good.
That pain burns the lesson into their memory forever.
They will never spell print wrong again in their life.
If you tell them?
They’ll do it again next lesson.
Or this classic:
You can say “that should be ==”.
Or you can say:
“Read it like English.”
And watch the penny drop.
That moment? That’s ownership.
Why this feels so hard for teachers
Because helping feels right.
Standing back feels wrong.
But Computer Science is one of the only subjects where:
Struggle is not a sign of failure.
It is literally the learning process.
The shift
Instead of:
“Let me see.”
Try:
“Tell me what you’ve checked so far.”
Instead of:
“You’ve missed a bracket.”
Try:
“What errors is it giving you?”
Instead of:
Fixing.
Start coaching.
The result is powerful
Students stop saying:
“Miss it’s not working.”
And start saying:
“Miss I think I know why.”
That’s when you know they’re becoming coders.
Not just students who copy code.
Final thought
If you are always the best debugger in the room,
your students never will be.
And Computer Science is the one subject where that really matters.
