  • The purpose of this study was to investigate the relationships between the pedagogical content knowledge in science teaching of pre-service early childhood teachers and their attitude toward science and science teaching efficacy belief. A total of 294 pre-service early childhood teachers responded to a questionnaire that examined their pedagogical content knowledge in science teaching, attitude toward science, and science teaching efficacy belief. The results of this study were as follows: First, teachers had average pedagogical content knowledge in science teaching. The groups of 3rd and 4th grades were significantly higher than the 2nd grade group. Second, the teachers' recognition was below average in attitude toward science and science teaching efficacy belief. The groups of 3rd and 4th grades were significantly higher than the 2nd grade group. Third, a meaningful statistical relationship was found between the pedagogical content knowledge in science teaching of pre-service early childhood teachers and their attitude toward science and science teaching efficacy belief. As the score of pre-service early childhood teachers in pedagogical content knowledge in science teaching became higher, the score in attitude toward science and science teaching efficacy belief became higher.

  • 교사들의 과학 교수 효능의 신념을 조사하고 이해하는 것은 과학 교수를 향상시키는데 가장 유력한 요소가 될 수 있음에도 불구하고, 이를 연구한 사례는 거의 없었다 본 연구의 목적은 초등학교 예비 교사들의 교사 양성 과정중 과학 교육 과목이 예비 교사들의 과학 교수 효능의 신념 즉, 자신의 과학 교수 효능감과 과학 교수 결과에 대한 기대감에 미치는 영향을 조사하는 것이다. 이를 위하여 서울교육대학교와 인천교육대학교에 재학중인 예비교사들이 한 학기동안의 과학 교육 과목을 마치고 나서 그들의 과학 교수 효능의 신념이 어느 정도 변화했는지를 측정하였으며, 이에 대한 결과를 t-test로 분석하였다. 연구의 결과로 미루어보아 예비 교사들이 학습한 과학 교육 과목은 그들의 과학 교수 효능감과 과학 교수 결과에 대한기대감을 모두 향상시켰다. 그러나 앞으로는 과학 교육 과목의 어떤 요소들이 그들의 신념을 변화시키는지 구체적으로 알기 위해 질적 연구와 함께 더욱 긴 기간 동안의 연구가 행해져야하며, 변화된 그들의 신념이 실제 초등학교 교사가 될 때까지 지속되는지를 조사하고, 지속될 수 있는 방법들이 연구되어야 할 것이다.

  • The purpose of this study was to investigate the relationships among elementary school teachers' high school and college backgrounds in science, their attitudes toward teaching science, their science teaching efficacy beliefs, and their instructional strategies. Both quantitative and qualitative research methodologies, were utilized in this study. This paper, however, presents only the results of the quantitative data analysis while expecting to report the qualitative data analysis outcomes afterwards. Four instruments were used to ascertain information concerning teachers' backgrounds in science(the number of high school science courses they took and the grades of courses, the number of college science courses and grades, the number of college science methods courses and grades), attitudes toward teaching science, science teaching self-efficacy beliefs(personal science teaching efficacy and science teaching outcome expectancy), and their instructional strategies(indirect, direct, and mixed methods). A sample of 340 practicing elementary school teachers participated in this study. To determine statistically significant results, Pearson's correlation coefficient was used to relate teachers' backgrounds in science, attitudes toward teaching science, science teaching self-efficacy beliefs and their instructional strategies. The correlation coefficients were statistically significant regarding four variables, teachers' backgrounds in science, attitudes toward teaching science, science teaching self-efficacy beliefs, and instructional strategies investigated in this study. These results can be interpreted that programs of teacher preparations and trainings which include science and science methods courses should help prospective and practicing teachers change in their attitudes and beliefs toward science teaching. It is expected that future studies concerning teachers' attitudes, beliefs, and behaviors toward teaching science can help to improve science teacher education in Korea.

  • This study is aimed to determine whether there is any meaningful correlation between predictors and is intended to examine the relative influences that the pedagogical content knowledge of science teaching, scientific attitudes, science teaching intentions have on their science teaching efficacy. The results, showed that the childcare center teachers' pedagogical content knowledge of science teaching, scientific attitudes, science teaching intentions, and science teaching efficacy are all correlated with each other. The teachers' science teaching efficacy are predicted by their scientific attitudes, science teaching intentions, and pedagogical content knowledge of science teaching-learning methods. Specifically, for teachers of 0 to 2-year-olds, their science teaching efficacy is predicted by their science teaching intentions and scientific attitudes. For teachers of 3 to 5-year-olds, their science teaching is affected by their scientific attitudes and their pedagogical content knowledge.

  • The purpose of this study was to investigate the effect on child care teachers' self-efficacy in teaching science. Subjects were 297 childhood teachers who were working at a day care center. The data were collected by using three questionnaires(Science Teaching Efficacy Belief Instruments, Inventory of Science Attitude, and Attitude Test for Child Care Teachers). The data were analyzed by Pearson's correlation and step-wise Regression. The results of this study are as follows; First, there were positive correlations between aptitude for child care teacher and self-efficacy in teaching science. Second, there were positive correlations between science attitude and self-efficacy in teaching science of child care teachers. Third, the significant predictors of self-efficacy in teaching science were interest in science, social value of science, interpersonal relationship management abilities, and positive emotions. The results of this study can be used to develop effective teacher training programs for early childhood science education.

  • This study examined the changes of preservice biology teachers' NOS pedagogical content knowledge through two consecutive science methods courses: NOS understandings; attitudes toward teaching science; difficulties of NOS teaching; NOS teaching strategies; and views of orientation of NOS teaching. During the science methods course I, the preservice teachers engaged in discussions and reflections on what science is and how scientific knowledge has produced, drawing NOS aspects from episodes of history of science, and planning the lessons cooperating NOS instructional objectives. Then the next semester, through the science methods course II, the preservice teachers had a chance of the simulated teaching by adopting NOS teaching and learning activities in the context of the secondary biology context. The preservice teachers, further, reflected on their NOS teaching. The results showed that the preservice teachers constructed the NOS pedagogical content knowledge. They significantly improved their views of NOS and its teaching(p<.05) after the science methods course I, and retained their understanding after the science methods course II(p>.05). The preservice teachers mentioned the difficulties of teaching NOS in the secondary biology context, and further suggested effective NOS teaching methods in their reflective journals.

A Study on Science Teaching Orientation and PCK Components as They Appeared in Science Lessons by an Experienced Elementary Teacher: Focusing on 'Motion of Objects' and 'Light and Lens' (한 초등 경력교사의 과학수업에서 나타나는 과학 교수지향과 PCK 요소들 사이의 관련성 탐색 -물체의 운동과 빛과 렌즈 단원을 중심으로-)

  • This study aims at exploring the features of science teaching orientation (STO) and its relationships with other PCK (pedagogical content knowledge) components. To do this, based on the definition of STO by Friedrichsen, Driel, & Abell(2011) and PCK model by Magnusson, Krajcik, & Borko(1999), we observed one experienced elementary teacher's science lessons for 21 lesson hours (10 hours of 'Motion of Objects' and 11 hours of 'Light and Lens') and carried out qualitative analyses of the data obtained from lessons observation, teacher interviews, and CoRe (content representation) responses. We analyzed the teacher's three aspects of STO (i.e. beliefs about the goals and purpose of science teaching, beliefs about the nature of science, and beliefs about science teaching and learning) which can converge into an overall STO of 'inquiry'. And these aspects of STO appear to interact differently with four PCK components (i.e. curriculum knowledge, learner knowledge, instructional knowledge, and assessment knowledge) depending on the topic of the lesson. It is hoped that this in-depth understanding of the features of STO and its relationship with other PCK components would provide useful information on how to monitor and improve STO and PCK of elementary teachers.

  • The purpose of the study was to suggest the characteristics and goals of the science teaching model for use as criteria in selecting the appropriate teaching model for science in secondary schools. These characteristics and the goals have been organized based on the analyses of the literature on the teaching and/or instructional model. The teaching models have been classified into four areas, and the characteristics and goals of each area have been summarized as follows: $\cdot$ Traditional models: teaching of scientific knowledge through lectures, acquisition of scientific knowledge through discovery, acquisition of inquiry process skills through inquiry-based teaching/learning $\cdot$ Transitional models: demonstration and discovery as teaching strategies, acquisition of inquiry process skills through inquiry approach, acquisition and change of scientific knowledge $\cdot$ Modernistic model - conceptual change models: differentiation of scientific knowledge, exchange of misconceptions for scientific concepts - learning cycle models: conceptual differentiation, exchange of misconceptions, acquisition of science process skills Also described in this paper are the model's characteristics and goals that can be used as the criteria for selecting the appropriate teaching model for the subject that will be taught.

  • The purpose of this study is to examine the effects of mentoring in enhancing the professionalism of low-experience science teachers on their general teaching and science teaching efficacies. The mentoring for low-experience science teachers was conducted on 24 science teachers with less than three years of experience over a nine-month period between April and December, 2016. The questionnaires developed by advanced researches were modified and used to test the teachers' general teaching and science teaching efficacies. As the result of a pre-test, the mean science teaching efficacy score was 3.02 points. In particular, the mean science teaching self-efficacy score was 2.86 points and the mean science teaching outcome expectancy score was higher at 3.17 points. In the domain of science teaching outcome expectancy, the mean for female teachers was higher than that of male teachers, and the mean for middle school teachers was higher than that of high school teachers in every domain. However, this result is not statistically significant. The results of a post-test showed that the mean science teaching efficacy score of mentee teachers increased to 3.08 points over the pre-test. In particular, the mean science teaching self-efficacy score was 3.11 points and the mean science teaching outcome expectancy score was 3.04 points in the post-test. This presents that the mentoring training conducted was effective in improving the science teaching efficacy of mentee teachers.
