Debugging is the curriculum
Most school CS is history of computers plus syntax dictation — a programming course with no programs. Mine inverts it. Week one, everyone ships something tiny and real. Then every concept — loops, functions, complexity — arrives as the fix for a problem their own code just hit. while(confused) we explain differently; we never say "it's easy".
- Ship something tinyWeek one ends with running code in every hand — a dice game, a name-art generator. Momentum before theory.
- Break it, read the errorError messages taught as friendly letters, not accusations. Debugging is the core literacy.
- Name the conceptThe loop, the function, the class — introduced as the fix for pain their own code just caused.
- Build for real usersTerm projects with actual users: the canteen app, the library portal. Board answers get written by people who've built.

Week one: everyone ships
Why my course starts with running code in every hand before a single definition — and how it rewired who signs up for CS.

My daughter said CS wasn't for people like her. One term with Ms. Rao and she's built a period-tracker app her friends actually use. She's doing B.Tech now.

The canteen app her students built has genuinely reduced Friday chaos. When it went down once, the whole school noticed. That's real software.

I'm an SDE now and I still hear her voice when I read a stack trace: 'it's a letter, not an accusation'. Best debugging habit I own.
