Chapter 8 introduces the final component of our framework, the Revise phase. This phase of the framework provides recommendations for conducting assessment, both formative and summative, that will allow teachers and instructional designers to determine the extent to which students have met the learning outcomes of a course or unit. In keeping with the general orientation of the book, we encourage an approach to assessment that is authentic and task oriented. The assessment practices proposed align with the activities and tasks recommended in the Build phase and are consistent with the teaching practices described in the Teach phase. In addition to assessment at the course level, we propose a set of criteria to evaluate the overall performance and quality of a course.
