Mathematical modeling, a key strand in mathematics, engages students in rich, authentic, exciting, and culturally relevant problems and connects abstract mathematics to the surrounding world. In this, article, the authors describe a modeling activity that can be used when teaching linear equations. Modeling problems, in general, are typically high…

Optometry educators can be assisted in making complex concepts understandable to students by using rhetorical devices such as metaphors, similes, analogies, parables, and allegories.
