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.

This study investigates how well pre-teachers in preschools aware the importance of science teaching methods, goals and efficacy, and how different the pre-teachers recognize the importance of methods and goals in science teaching according to the levels of their science teaching efficacy. The subjects were 207 pre-service preschool teachers in Chonnam University and Chonbuk University. The data were collected by using three questionnaires("Science teaching efficacy", "Science teaching goal" and "Science teaching method"). The data were analyzed by a t-test and descriptive statistic. The results are as follows: first, the efficacy levels of the pre-teachers are higher than the average. The pre-teachers perceive a 'process-oriented' goal more importantly than a 'content-oriented' goal in early science education. Also, they recognize science teaching methods as being significant in the order of an 'interactive' approach, an 'activity-discovery' approach and a 'knowledge-transmission' approach. Second, the pre-teachers with high teaching efficacy recognize a 'process-oriented' goal as being more important than those with low teaching efficacy do.

본 논문에서는 모델 구성을 통한 교수-학습 활동을 지구과학 수업을 위한 유용한 방법의 하나로 제안하였다. 모델 구성은 지구과학자들이 직접적으로 경험하기 어려운 지구과학적 현상이나 과정을 연구하기 위하여 동원하는 방법으로서, 지구과학의 본질적 속성을 반영한 수업을 개발하는 데 이용할 수 있다. 모델 구성을 통한 지구과학 수업은 학생들이 지구과학적인 현상이나 과정에 대한 모델을 창안하고 학생들이 서로 모델에 대한 의견을 교환하며 지속적으로 모델을 수정해 나가는 순환적인 과정(creation-communication-change cycle)으로 진행될 수 있으며, 학습자들의 사고 과정을 촉진시켜 여러 가지 학습 효과를 가져올 수 있다. 따라서, 지구과학 교육 현장에서 학생들이 능동적으로 참여하는 지구과학 수업을 위하여 모델 구성을 통한 교수-학습 활동이 적극적으로 실천되고 그 효과를 자세히 검토하는 일이 필요하다.

This study examined the effect of simulated instruction activities based on a constructivist teaching approach on epistemological belief, science teaching efficacy belief, and teaching motivation. The RTOP (Reformed Teaching Observation Protocol) played a role to guide preservice biology teachers to obtain insights on current reformed teaching and to further practice teaching based on constructivism. The results indicated that preservice teachers changed their epistemological beliefs toward more sophisticated views, especially for 'simple knowledge'. They also improved their science teaching efficacy beliefs, both personal science teaching efficacy belief (PSTEB) and science teaching outcome expectancy (STOE). In addition, these perservice teachers decreased their scores of extrinsic teaching motivation. The Pearson correlation represented the negative relationship between personal science teaching efficacy belief (PSTEB) and extrinsic teaching motivation. After intervention, the preservice teachers mentioned inquiry, active participation and discussion as ideal science teaching methods and qualifications for science teachers.

Even though identical science textbooks are used in elementary science classes, differences exist in teachers' teaching practices. The purpose of this study was to understand the relationships between elementary teachers' beliefs of science learning and their science teaching practices. An Likert-scale survey and interviews were performed on four elementary teachers to obtain information about the beliefs of teachers in science learning. In order to understand their teaching practices and the relationships between teachers' beliefs and their teaching practices, 2 classes per each teacher were recorded and instruction analyses were performed in the aspects of teaching contents, methods, and learning environments. The results showed that teacher A and B, who held traditional beliefs of science learning, taught their classes mainly based on teacher's explanation. While, teacher C and D, who held constructive beliefs of science learning, reorganized the contents of textbooks and applied various teaching methods and strategies in conducting their teaching practices. There were differences in teachers' beliefs of science learning and teaching practices. These differences in beliefs were related with their science teaching practices.

The purpose of this study was to investigate relations between middle school science teachers' perception of students' learning styles and their teaching style. Data were collected by in-depth individual interviews with 20 experienced science teachers (14 years of teaching experience in average). Results indicated four categories of the relations: i.e. teachers implemented their teaching style (1) matching students' learning styles, (2) supplementing students' insufficient learning styles, (3) teacher-centered, but matching the diverse students' learning styles, and (4) based on their values and convictions. In general, teaching styles of the teachers did not match with their perceptions of students' learning styles. Instead, their teaching styles seemed to be more affected by their personal values and convictions.

This study was designed to enhance preservice teachers' self-efficacy beliefs and pedagogical content knowledge (PCK) through scientific investigations based on current science education reforms. To do so, a science methods course was revised to include modeling effective scientific inquiry practices as well as designing and teaching scientific investigations in the K-5 practicum classrooms (Revised Science Methods Course). This study assessed the following research questions: (1) What level of PCK do preservice teachers have before and after the completion of RSMC; (2) To what extent do participants change their self-efficacy in science teaching after completing RSMC; and (3) Is there any correlation between participants' changes in self-efficacy and the level of PCK. Participants were 76 preservice teachers enrolled in a science methods course offered at a medium-sized university in the midwestern United States. This study employed the STEBI-B survey and the PCK rubric. There result of the study indicated that there was significant increase in Personal Science Teaching Efficacy (PSTE) of the participant preservice teachers after the completion of the course. Based on the PCK rubric analysis, there was a significant increase in mean scores of the post-RSMC lesson compared to those of the pre-RSMC lesson. The correlational analysis of participants showed a positive correlation between changes in self-efficacy and the level of PCK. Thus, it may be concluded that the reform-based science methods course had a positive impact on participants' self-efficacy in science teaching through correcting misconceptions, developing higher level of PCK, and modeling scientific investigation in their practicum schools.

이 글은 체육 및 운동과학 연구에서 각종 통계적 방법의 출현을 역사적으로 개관하고 이들 통계적 방법의 출현시기를 미국의 경우와 비교함으로써 한국 체육학연구의 학문적 성장을 확인하고 이들 방법 적용과정에서 나타난 문제점을 밝히는데 목적이 있다. 이러한 목적을 달성하기 위해 통계적 방법 관련논문을 분석하고 통계적 방법이 체육 현장에서 어느 정도 중요하게 다루어 질 수 있는지를 확인하기 위해 측정,평가 담당교수의 학문적 배경과 교육적 경력을 조사하였다. 전공자의에 대한 의 체육학이 아직 학문적으로 자리를 잡기 전인 최초 태동 시기에 적용된 통계적 방법을 미국의체육학회지(RQES)와 비교해 볼 때 동일한 통계적 방법의 적용시기는 약 30년 차이가 있다. 이러한 차이는 미국에서 1980년도에 나타나기 시작한 진보된 다변량 통계기법을 1990년대에 적용하기 시작하면서 급속도로 좁혀졌으며 현재는 동일한 시기에 나타나고 있다. 그러나 진보된 통계적 기법의 출현에도 불구하고 이들 기법을 적용하는데 필요한 기본가정이 충족되었는지에 대한 검토 없이 적지않은 논문이 보고되고 있다. 담당교수의 학문적, 교육적 배경이 통계학과 거리가 있는 교수가 47%로 나타남으로써 가르치는 내용과 범위에서 적지않은 제약이 따르고 있다. 또한 전문가에 의한 평가체제가 확립되지 못함으로써 적용된 통계적 기법의 적절성을 평가하는데 장애가 되고 있다.

The Interdisciplinary-Multistrategic Science Education Program(IMSEP) is designed as an efficient program for the education of the gifted in science. An example of the contents is developed, which encompasses mathematics, physics, chemistry, astronomy, and biology. In the program, the complexity(interdisicplinarity) of scientific contents and instructional strategies used to deliver the scientific contents are designed to be correlated to each other in such a way that as the scientific contents gets more complex, the scientific skill to be taught by the instructional strategy becomes deeper. Through the careful balance between the scientific contents and the instructional strategies student's scientific knowledge and scientific skill will develop balanced and the effectiveness of science education will be maximized.
