Provides a brief overview of single-subject research designs. This method exercises its power by examining changes in single subjects' responses over time across experimental conditions. Describes a classroom project in which students collect repeated measures of their own behavior and graph the data. (MJP)

Common elements identified as context variables that may affect student evaluation of instruction are explored, and the literature on student ratings of teacher effectiveness is reviewed. Sociocultural context variables (gender, race, ethnicity, and social class variables) are discussed in terms of stereotyping and prejudice found with…
