다국어 초록 (Multilingual Abstract)

The purpose of study was to investigate practicing elementary teachers` pedagogical content knowledge and the significant predictors of their pedagogical content knowledge in science teaching. The PCK instrument was used to measure elementary teachers` pedagogical content knowledge. It consists of 6 factors to measure teachers` pedagogical content knowledge of 1)instructional methods. 2)representations, 3)contents, 4)evaluations, 5)students, and 6)curriculum. A questionnaire that consists of 7 questions regarding the teachers` degree, their number of years of teaching, their choice of teaching science, their personal science teaching efficacy, their science teaching outcome expectation, their science instructional methods, and their attitudes toward teaching science, was also used to identify the information as to significant predictors of teachers` pedagogical content knowledge. A sample of 332 practicing elementary teachers participated in this study. To determine statistically significant predictors. Pearson`s correlation coefficient and multiple regression methods were used to analyze the results. The results showed that the significant predictors of practicing elementary teachers` pedagogical content knowledge were their number of years of teaching, their science instructional methods, their personal science leaching efficacy and their attitudes toward teaching science. Further research of how teachers develop and construct their pedagogical content knowledge is recommended especially through the use of varied research methodologies that include qualitative methods.
