Recursion is one of the most important and hardest topics in lower division computer science courses. As it is an advanced programming skill, the best way to learn it is through targeted practice exercises. But the best practice problems are time consuming to manually grade by an instructor. As a consequence, students historically have completed only a small number of recursion programming exercises as part of their coursework. We present a new way for teaching such programming skills. Students view examples and visualizations, then practice a wide variety of automatically assessed, small-scale programming exercises that address the sub-skills required to learn recursion. The basic recursion tutorial (RecurTutor) teaches material typically encountered in CS2 courses. Students who used RecurTutor had significantly better grades on recursion exam questions than did students who used typical instruction. Students who experienced RecurTutor spent significantly more time on solving recursive programming exercises than students who experienced typical instruction, and came out with a significantly higher confidence level.
