PACKAGE

   Interactive domain reasoner for statistics, based on the feedback services 
   of the Ideas framework. Provides feedback and hints on step-by-step 
   construction of hypothesis tests by students. Test types supported include 
   z-tests, t-tests for one group, dependent groups and independent groups, 
   correlation, ANOVA and Chi-square tests. The domain reasoner is used by the 
   learning environment Numworx (www.numworx.nl) and is available for 
   implementation in other learning environments as well.  

PROJECT

   Ideas (Interactive Domain-specific Exercise Assistants) is a joint research
   project between the Open University of the Netherlands and Utrecht
   University. The project's goal is to use software and compiler technology to
   build state-of-the-art components of intelligent tutoring systems (ITS) and
   learning environments. The 'ideas' software package provides a generic
   framework for constructing the expert knowledge module (also known as a
   domain reasoner) for an ITS or learning environment. More information about
   the project can be found on the project's homepage:
