Professor of Software Technology for Learning and Teaching at the Institute of Information and Computing Sciences of Utrecht University (95%), and professor of Software Technology at the School of Computer Science of the Open University.
I develop software technology to support learning and teaching, and advanced methods for constructing software.
Teaching and Learning
The role of ICT in teaching and learning is increasing. We use advanced software technology to develop better tools for teaching and learning.
- In the Communicate! project we are developing a serious game for practicing communication skills.
- In the Math-Bridge project we add feedback services to ActiveMath, and we develop on-line math-bridging courses.
- Together with Alex Gerdes and Bastiaan Heeren I am working on providing feedback in interactive learning tools for programming. We have developed a programming tutor for Haskell.
- Our feedback services are connected to the version of the Digital Mathematical Environment used by the series of Dutch mathematics text books `Getal en Ruimte'.
Generic programs are programs that abstract over types. Generic programs can be used to address several common programming patterns.
- Together with José Pedro Magalhães (now at Oxford University), and Sean Leather, I have worked on several aspects of generic programming, such as generic programming libraries.
- Andres Löh, Ralf Hinze, and I have developed Generic Haskell. Generic Haskell is an extension of the functional programming language Haskell, with which programs that work for large classes of datatypes can be written.
- Generic haskell is a sequel to PolyP (see Patrik Jansson's page about polytypic programming).
My publications appear on a separate page.
