Plain language
Harvard's well-known introductory computer science course, also taught free online.
As stated in the literature
Harvard University's flagship intro CS course, notable here for shipping its own guardrailed AI helper (the 'Duck') tuned to nudge students toward answers rather than hand them finished code.
Why it matters: It shows how a course can add an AI helper that guides students toward learning instead of just handing them the answer.
For example, a beginner anywhere in the world can follow CS50's lectures and assignments online without paying tuition.
