Keep it clear: how to verbalize mathematics in an inclusive way

This talk will highlight the often overlooked problem of ambiguity in spoken mathematics, providing examples of how an incorrect presentation of mathematical formulas and expressions can create a barrier between the student with low or no sight and the subject. After identifying the major factors that contribute to a wrong verbalization of mathematics, a solution will be presented in MathSpeak, a set of best practice guidelines to erase every form of ambiguity in the mathematics spoken in the classroom. The key principles of this system will be presented, together with a brief summary of the scientific evidence of its impressive positive impact.
