Reliability of Coding of the System for the Analysis of Classroom Communication (SACC). Center for the Study of Evaluation Working Paper Number Two.
Jones, Margaret Hubbard
This study assesses the reliability of the System for the Analysis of Classroom Communication (SACC) devised to permit the gathering of data descriptive of classroom communication between teacher and pupils for evaluative purposes. The reliability used was called inter-observer agreement. The measure of inter-observer agreement used was the Scott coefficient which takes into account the number of categories in the system and the frequency with which each is used. The sample consisted of six schools, 20 teachers, eight subject matters, and eight grade groups. Students were of average socioeconomic status, most were "Anglos" but some were Mexican-Americans. There were 33 sessions varying in length from seven to 34 minutes; a session being defined as a coherent curricular unit. The two observers, who coded at the same sessions, were advanced graduate students in education. Results indicated that the level of inter-observer agreement was significantly high enough to permit use of the instrument for evaluative purposes. A modification of procedure should be used when the goal is evaluation of a school or a grade level. (EK)
