We report the results of a pilot validation study of the Quality Assessment in Science Notebook, a portfolio-like instrument for measuring teacher assessment practices in middle school science classrooms. A statewide sample of 42 teachers collected 2 notebooks during the school year, corresponding to science topics taught in the fall and spring. Each notebook was scored on 9 dimensions of assessment practice by 3 trained raters. Our analysis investigated the reliability and validity of notebook ratings, with particular emphasis on identifying key sources of error in the ratings. The results suggest that variation in teacher practice across notebooks (i.e., over time) was more important than idiosyncratic rater inconsistencies as a source of error in the scores. The validity results point to a dominant factor underlying the ratings and some predictive power of notebook ratings on student achievement. We discuss implications of the results for measuring assessment practice through artifacts, drawing conceptual and methodological lessons about our model of assessment practice, the consistency of raters, and the estimation of variance over time with classroom-based measures of instruction.
