When teaching Scala I wouldn't start with the jargon first -- start from the problem, show the solution, then name the patterns used. When teaching algebraic data types, for example, we start with more familiar OO terminology like "is-a" and "has-a", and then say we have this other name for these patterns. To be clear, I have a horse in this race: I teach Scala (and have written a book on it, which you can find here: http://underscore.io/training/courses/essential-scala/ http://underscore.io/training/courses/essential-scala/). I also strongly believe Scala has been held back by poor teaching.
