Getting comfortable with loops, conditionals, and functions early makes every future CS course easier — and Justin explains these building blocks by tying them to problems students can visualize, like simulating physics or processing data. His background spans physics, applied math, and programming,...

High school CS courses often move fast from basic control flow to more complex topics like arrays, sorting algorithms, and introductory object-oriented programming. Noah's computer science degree from Duke means he can explain why a for-loop works the way it does, not just show the syntax. He adjust...

That first encounter with loops, conditionals, and functions can feel overwhelming when everything is new vocabulary. Allison breaks programming logic into small, testable pieces — write three lines, run them, see what happens — so students build intuition for debugging and problem decomposition bef...

Getting through high school CS often means wrestling with your first real programming concepts — loops, conditionals, arrays, recursion — without much intuition for why they work. Florence, a Duke CS major and three-time teaching assistant, unpacks these ideas by connecting abstract logic to tangibl...

For students encountering loops, conditionals, and arrays for the first time, the leap from "I typed the code" to "I understand why it works" can be steep. Jonathan bridges that gap by walking through each concept with concrete examples and building up to small projects that make the logic tangible....

High school CS courses often move fast from basic control flow to arrays and object-oriented programming, and students who can't explain *why* a loop works will struggle when projects get more complex. Tolu uses a question-driven approach — instead of handing over solutions, he walks students backwa...

AP Computer Science and introductory programming courses often trip students up at the same points — loop logic, array manipulation, and understanding how methods pass data around. Michael's UCLA computer science background means he can trace through code line by line and show exactly where a studen...

For students encountering loops, conditionals, and arrays for the first time, the leap from "I followed the example" to "I can solve a new problem" is the hardest part. Anna bridges that gap by teaching structured problem decomposition — breaking a coding challenge into smaller logical steps before ...

Kashish's engineering coursework at Brown means she writes and debugs code regularly, which gives her a practical lens for teaching high school CS topics like variables, control flow, and basic algorithmic thinking. Her experience leading SAT prep classes also sharpened her ability to break down unf...

A lot of high school CS courses move fast from basic loops and conditionals into AP-level topics like recursion and array manipulation. Rhamy breaks each concept into small, buildable steps — writing actual programs rather than just reading pseudocode — so the logic sticks before the syntax piles up...
