We designed a professional development (PD) program to increase the teacher efficacy of mathematics teachers. We randomly assigned 106 grade 6 teachers in one school district to treatment and control conditions in a delayed treatment design. The PD explicitly addressed four sources of teacher efficacy information identified in social cognition theory (Bandura, 1997).Treatment teachers outperformed control group teachers on three measures of teacher efficacy but results were statistically significant only for efficacy for classroom management. We attributed the teacher efficacy effects of the PD (6% of the variance) to the priority given in the PD to management of classroom discussions and overt attempts by PD leaders to redefine teacher conceptions of classroom success.
Effects of Professional Development on Teacher Efficacy:
Results of a Randomized Field TrialResearch on the antecedents and consequences of teacher efficacy is a growth industry, and for good reason: Teacher efficacy, at both the individual and collective level, consistently predicts a host of enabling teacher beliefs, functional teacher behaviors, and valued student outcomes. Despite the importance of the construct there have been few studies reporting the effects of interventions intended to increase teacher efficacy. In this article we will consider the potential of Professional Development (hereafter PD) as a stimulus for enhancing teacher beliefs about their capacity. We will illustrate our argument with data from a randomized field trial which examined the teacher efficacy outcomes of a PD program for grade 6 mathematics teachers.
Theoretical Framework The ConstructTeacher efficacy is a teacher's expectation that he or she will be able to bring about student learning. It is a specific case of self-efficacy, i.e., "beliefs in one's capabilities to organize and execute the courses of action required to produce given attainments" (Bandura, 1997, p. 2), directed toward the teacher as an agent of student achievement. Teacher efficacy influences behavior through cognitive processes (especially goal setting), motivational processes (especially attributions for success and failure), affective processes (especially control of negative feelings), and selection processes (Bandura, 1993;. Teachers who believe they will be successful set higher goals for themselves and their students, try harder to achieve those goals, and persist through obstacles. Individuals who believe they will fail avoid expending effort because failure after trying hard threatens self-esteem. Self-efficacy is situational; it is not a generalized expectancy. It develops from a subject's appraisal of past experience with the task or with 4 activities similar to it, although perceptions of efficacy can be modified by other sources of information such as observing the performances of others (Bandura, 1997).Teacher efficacy is a self-perception, not an objective measure of teaching effectiveness.However, reviews of research (Goddard et al., 2004;Ross, 1998; Tschannen-Moran, Wo...
