" summary

A semester-long Clojure course at a small liberal-arts college teaches beginners the functional core in 37.5 hours over 15 weeks, starting from function composition and emphasizing map filter reduce and persistent data structures; teaching uses live REPL coding, pair help, and paper-style reading exercises; class size is small — 14 students finished — and a Collatz exercise finds 871 produces a sequence of length 178, showing concrete, testable results.
