Helping students build a mental model of computation

Introductory computer science classes are known for having a high attrition rate. Some authors believe this is due to students’ difficulties in establishing a mental model of computation. We present a tool designed to assist students in actively building a mental model of computation, and evaluate its use in an introductory programming class. We show use of the tool leads to 40% increase in course completion and that the students believe the tool helps them understand programming.
