Ideas: interactive domain reasoners
Domain reasoners help students solving interactive exercises in learning environments, such as ActiveMath, MathDox, and the Digital Mathematical Environment from the Freudenthal Institute.
Ideas is a framework for developing domain reasoners that give intelligent feedback. Using Ideas, we have developed domain reasoners for solving algebra problems such as quadratic equations, but also for logic, and programming.
- giving a hint for the next step
- showing a worked-out solution to an exercise
- reporting a common error (or buggy rule)
- reporting a correct but suboptimal step
- decomposing an exercise into subexercises, etc.
- Ask-Elle (introductory movie), our functional programming tutor, supports developing small Haskell programs. If you want to experiment with evaluating functional programs, you can use the Haskell Expression Evaluator.
- IPT is a tutor for imperative programming.
- At the Open Universiteit Nederland, we use our domain reasoners in a learning tool for rewriting logical expressions to disjunctive normal form.
- Together with the Freudenthal Institute, we have incorporated our domain reasoners in the Digital Mathematical Environment, to support solving linear, quadratic, and higher-degree equations and inequations, to simplify and evaluate fractions, expressions using powers and square roots, etc.
- Our domain reasoners are used within the Math-Bridge project, to support interactive exercises in ActiveMath in bridging courses all over Europe.
- We have developed domain reasoners for linear algebra, in particular for gaussian elimination, gram-schmidt, solving systems of linear equations, in cooperation with the TU/e, accessible via MathDox.
The ideas framework uses rewrite strategies for specifying how to solve exercises. The main ideas are described in our paper Specifying Rewrite Strategies for Interactive Exercises.
Several other aspects of our domain reasoners are described in the various publications about our work.
Information about our framework, documentation, etc, is available on our trac.
