Therefore in law school teaching argumentation is essential.
Information technology can provide useful support in argumentation courses.
In the verbal approach, the argument is mainly presented in a verbal style, for instance in the form of a text or a written-out dialog. In the visual approach, the argument is mainly presented in a visual style, for instance in the form of a tree of sentences. We discuss the opportunities of the two approaches for teaching legal argument. Our conclusion is that neither approach is fully satisfactory for teaching legal argument if it is taken to its extreme, but that a hybrid combination of verbal and visual elements should be striven for.
