Résumé
The notion of heterogenous classrooms is en vogue and typically related to certain challenges in communication. Combining teaching experience in an international class and a special education class for hearing-impaired children, we want to propose a certain type of silent video. The special format puts strict conditions on the representation of mathematical notions and objects. We want to highlight these consequences thoroughly with the example of a tangent to a graph of a function by suggesting three story boards with different contexts.
