Please don't read the following with the impression that it is any kind of official policy. Defining a WID class WID currently exists at Boise State not at the level of a university-wide program, but at the level of individual classes and individual instructors. In a WID class, assigned writing is a significant part of the course work.
Students complete formal writing assignments, but they also do frequent informal writing.
The informal writings are used to engage students with the course material but are not graded. A more detailed look at formal and informal writing assignments will help clarify what we mean by a WID class. When we think of assigning writing in a class, formal assignments are what we think of first. They give students an opportunity to experience the ways of thinking in the discipline and practice using its language. They provide another means, besides exams, for students to demonstrate their grasp of the material.
