The main purpose of intelligent problem solving environments (IPSEs) is to offer students the opportunity to acquire knowledge while working on a sequence of problems chosen from the domain. Up to now we have developed IPSEs for various curricula and applications (computer science, hydraulics, chemistry, economic simulation games and causal modeling). On the surface being very different all IPS...

We want to describe the design of PULSE (Pneumatic Learning and Simulation Environment), an Intelligent Problem Solving Environment (IPSE) for pneumatic circuits based on a cognitive theory of knowledge acquisition (ISP-DLTheory). PULSE offers tasks given as a textual description and a time-discrete kind of a distance-time diagram. It supports unconstrained design of pneumatic circuits. PULSE o...

This paper examines the work undertaken in the UK Alvey funded project IPSE 2.5 1 from the point of view of the approach taken to the development of the core system. It outlines the reasoning which led to the decision to base the system on a \active process" core rather than the more traditional approaches which have tended to support an entity derived model.It gives a brief overview of the pro...
