This paper describes an approach to the design of online help for programming tasks and modelling tasks, based on a theoretical framework of problem solving and learning. The framework leads to several design principles which are important to the problem of when and how to supply help information to a learner who is constructing a solution to a given problem. We will describe two example domains where we apply these design principles: The ABSYNT problem solving monitor supports learners with help and proposals for functional programming. The PETRI-HELP system currently under development is intended to support the learning of modelling with Petri nets.
