Cambridge University Press 2004. Systematic classroom observation methods have been widely used in the past several decades to investigate effective teaching practices (Brophy & Good, 1986; Stallings & Mohlman, 1988; Waxman, 1995; Waxman & Huang, 1999). One of the most important uses of the method has been to determine which teaching practices improve student learning (Waxman & Huang, 1999). Most classroom observation instruments typically focus on the teacher as the unit of measurement or observation, and thus they describe a variety of instructional behaviors in which teachers engage. There are limitations, however, with teacher-based classroom observation instruments. First, teacher-focused instruments suggest that teaching practices directly impact student outcomes, without acknowledging that student behaviors impact teacher behaviors as well. Another concern with teacher-focused observation systems is that they often ignore student behaviors that have a greater impact on student outcomes than teacher behaviors. Another limitation of teacher-based observation instruments is that they generally do not allow researchers to examine individual student behaviors, particularly differences by critical attributes such as student sex, ethnicity, or grouping classification (e.g., gifted/nongifted, resilient/nonresilient, monolingual/bilingual). A final concern with teacher-centered observation systems is that they are often very threatening to classroom teachers. Many teachers are reluctant to volunteer to participate in classroom observation research because they know the focus of attention is on the teachers and their instructional practices. This chapter describes the uses of a systematic classroom observation instrument, the Classroom Observation Schedule (COS), that was designed to address some of the previous concerns of classroom observation by specifically focusing on individual students rather than the teacher (Waxman, Wang, Lindvall, & Anderson, 1990a, 1990b).
