An Examination of Change in Teacher Self-Efficacy Beliefs in Science Education Based on the Duration of Inservice Activities

Abstract

Researchers investigated the optimum length of teacher inservice activities where increasing teacher efficacy was the goal. Participants were elementary science teachers from seven teacher enhancement projects conducted from 1992-99. The length breakdown of each program was: 1992--6 weeks; 1994--6 weeks; 1995--4 weeks; 1996--4 weeks; 1997--4 weeks; 1998--3 weeks; and 1999--2 weeks. In each of the projects, teachers completed the Science Teaching Efficacy Belief Instrument (STEBI) on the first and last days of the inservice workshops. The STEBI examined personal science teaching efficacy (PSTE) and science teaching outcome expectancy. Data analysis indicated that there was no statistically significant difference between the mean PSTE gain scores on the three contrast variables among the four groups of teachers whose PSTE pretest scores were greater than or equal to 50. This may be due to the fact that teachers already scored high on the PSTE scale. Among teachers whose pretest PSTE scores were less than 50, there were significant gains when comparing the mean gain scores from teachers in the land 3-week sessions and teachers in the 4and 6-week sessions. It was found that inservice intervention programs had the greatest impact on the efficacy of those teachers who began the program with the lowest efficacy. Given the consistent relationships demonstrated between teacher efficacy and positive student outcomes, inservices impacting teachers' low efficacy are worth close examination.
