Abstract:

The majority of people, mathematicians included, think that writing out formulas is exactly what we call writing in mathematics. I was guilty of the same preconceptions before I started to work with the Writing Across the Curriculum Project at Medgar Evers College. The definition of writing to learn that we use at MEC helped me come up with the idea that served as the basic principle for my further experiments and conclusions as I implemented writing to learn in mathematics.
