introduction
The Role of Classroom Assessment
Classroom assessment has been largely ignored in the research and practice of assessment theory. This is not to say that it has been inconsequential to classroom practice. To the contrary, the topic of classroom assessment has become more and more popular in the practitioner literature. For example, the book Classroom Assessment: What Teachers Need to Know is in its eighth edition (Popham, 2017). Many other publishers continue to release books on the topic. This trend notwithstanding, technical literature in the 20th century has rarely mentioned classroom assessment. As James McMillan (2013b) notes:
Throughout most of the 20th century, the research on assessment in education focused on the role of standardized testing …. It was clear that the professional educational measurement community was concerned with the role of standardized testing, both from a large-scale assessment perspective as well as with how teachers used test data for instruction in their own classrooms. (p. 4)
As evidence, McMillan (2013b) notes that an entire issue of the Journal of Educational Measurement that purported to focus on state-of-the-art testing and instruction did not address teacher-made tests. Additionally, the first three editions of Educational Measurement (Lindquist, 1951; Linn, 1993; Thorndike, 1971)—which
