The major portion of this report reviews a recent study that replicated and extended earlier research by Schalock, Beaird, and Simmons (1964, ED 003 620) on the use of situation reaction tests (using motion picture representations of classroom situations as test stimuli) to predict teaching behavior in the classroom. Chapters I and II summarize the 1964 study which pretested 40 student teachers using a paper and pencil attitude scale plus 3 situation reaction tests with different response modes; scores were correlated with observational measurements of management behavior in the classroom during student teaching. Chapter III reports the replication study which was extended to include situational data in the prediction scheme and which studied 39 experienced teachers in addition to 39 student teachers. In Chapters V and VI the results are discussed with reference to test theory, observational research methodology, and the measurement of teaching behavior in situation. Included are 20 statistical tables, a 16-item bibliography, and an example of the behavior profiles prepared for each teacher who took part in the study. A supplementary document to this report, "An Overview of the Teaching Research System for the Description of Teaching Behavior in Context" (developed for use in this study), is also in the ERIC collection.
