ALCOCK, L. and INGLIS, M., 2010. Visual considerations in the presentation of mathematical proofs. Seminar.net - International Journal of Media, Technology and Lifelong Learning, 6 (1), pp. 43-59.
This article is about visual issues in the presentation of mathematics within
teaching situations. It focuses particularly on the presentation of proofs to
undergraduate students. We describe some of the decisions that a lecturer
must make when presenting a written proof, from the layout of individual
equations to the layout of a whole argument on the page. We consider the
way in which these decisions are made explicit for lecturers who construct
electronic learning resources termed e-Proofs, and conclude by discussing the
constraints and affordances of this technology.
