Abstract

This study investigates the generalizability of the Protocol for Language Arts Teaching Observation (PLATO) as a measure of teaching quality across two subjects and within a Scandinavian context. Towards this end, we explore whether teaching quality is measured equivalently in mathematics and language arts classrooms. To pursue this objective, we conduct Generalizability (G) Studies. The data consist of videotaped lessons from 30 classrooms that were scored on the twelve PLATO elements by certified raters (666 lesson segments). G Studies reveal that most of the variance explained in scores is due to variation across subjects. This suggests that teaching quality varies systematically between mathematics and language arts classrooms. Implications for research and practice are discussed.
