Introduction: Seeing Clearly in an Age of Measurement
Jan Steen’s A School for Boys and Girls (1670) offers neither an idealized vision of education nor a condemnation of its difficulties. Instead, the painting presents a classroom animated by the full range of human behavior: attention and distraction, discipline and resistance, order and improvisation. The proverb often associated with the image, What use are glasses or light if the owl does not want to see?, invites reflection on the limits of instruments designed to clarify understanding. Improved tools do not guarantee improved perception. Illumination does not compel insight.
I began teaching in 2007, the same year Missouri implemented the End of Course assessment program. Because of this historical coincidence, my professional life has unfolded within an educational environment shaped by the pursuit of clarity through measurement. Standardized testing, data dashboards, data walls, and accountability systems have formed part of the structural context in which my understanding of teaching has developed. Over time, I have come to recognize both the value and the limits of these instruments. Numbers offer visibility into certain aspects of learning, yet the deeper processes through which individuals construct meaning often resist full quantification.
Steen’s classroom provides a visual metaphor through which to consider the contemporary educational landscape. Each figure, object, and gesture reveals a dimension of learning that complicates simplistic interpretations of success or failure. The painting reminds us that education has always involved negotiation between structure and agency, between institutional expectation and human development. The present moment does not represent a departure from this tension but its continuation under new conditions shaped by technological change and expanded accountability.
The reflections that follow consider what standardized measurement reveals and what it necessarily obscures. Drawing upon constructivist philosophy, qualitative research traditions, and the work of scholars such as Alfie Kohn, John Dewey, and Gert Biesta, the essay explores the relationship between visibility and understanding within educational systems. Steen’s classroom serves as a visual companion throughout, reminding us that learning has always unfolded within imperfect environments populated by individuals striving to see clearly.
The question is not whether measurement has value but how measurement relates to the broader aims of education. If spectacles sharpen vision, wisdom determines what is worth seeing.
