In Chapter 3 you learned a process that helps develop or modify learning-teaching activities and units of study based on standards. At this point you're ready to focus on student products and performances as evidence of the learning that results from those activities and units.
You need evidence to document student progress toward standards. Products and performances may be thought of as sources of evidence; these documents, artifacts, demonstrations, and interactions provide proof of each student's progress in attaining the unit's standards. Products and performances may be categorized as (a) written, (b) visual, (c) oral or aural, (d) built and made, or (e) as combinations of these categories. See Figure 4.1 for examples of products and performances.
