The DiMo tool provides support for the acquisition of formal modelling competencies using propositional logic. We extend the tool by generic capabilities to generate problem-specific feedback to students. This allows them to visualise the result of their modelling attempts in terms of the modelled problem at hand, thus helping students to initiate corresponding learning cycles.enpropositional logicteaching modellingfeedback systemsvisual feedbackerror-driven learningText/Conference paper10.18420/delfi2024_082944-7682
