Although most people probably associate the term “assessment” with quizzes and exams, in reality these high-stakes activities represent a small subset of assessment opportunities. Educationally, assessments can be broken into two larger categories: summative and formative. Most of our experience with assessment usually comes in the form of summative assessment. We have our students take exams or write papers at the end of a chapter. Summative assessments are valuable because they let us know whether our students have successfully learned what we wanted them to learn. Summative assessments, however, are limited in that they provide little information to guide teaching because they usually serve as the endpoint of some instruction.
"Whereas summative assessments are assessments “of” learning, formative assessments are assessments “for” learning. They help to guide instruction and provide valuable information for the instructor and for the learner. Formative assessments can help to drive instructional decision-making and allow the instructor to “take the temperature” of the class. In the discussion with my colleague, I outlined the different phases of blended learning and highlighted opportunities for formative assessment in each."
