The goal of this thesis is to develop a concept of computer-based tutoring of text problems that include both model building and model transformation . Text problems are used for practicing problem solving in domains such as project management, database-design, and linear programming. A brief overview of related research shows that a main deficiency of current coaches for text problems is that they do not cover model building but that they focus on model transformation.
Project management serves as a test bed.
Active learning in this domain typically uses text problems. Furthermore, the curriculum is algorithmically tractable and thus forms an appropriate base for this research. Text problems consist of problem texts that informally describe the problem structure. Formalisation means building a formal model from this textual information. The model is thus a structured representation of the unstructured textual representation.
