A web-based problem solving tool for introductory computer science.

ABSTRACTWe present a "Problem Solving Tutor" - a web-based educational tool for learning through problem solving. The tool contains more than 1,400 problems, mainly introductory programming problems, math and logic puzzles. All problems are interactive and the system gives students immediate feedback on their performance. The tool makes individual predictions of problem solving times and therefore is able to recommend each student a problem of suitable difficulty.
