The method of this course is based on working with self-made paper models. The construction instructions are included in the booklet. By working with the models, students develop their imagination and spatial thinking. They can feel the invisible edges of the model and thus "grasp" how the representation of the body should be done. The ability to abstract is enhanced. The course includes tasks that correspond to the level of the special performance assessment for obtaining the qualifying secondary school diploma – Technology – Technical Drawing at Bavarian secondary schools.
