The purpose of this study was to identify the effectiveness of science writing on organizing scientific knowledge and improving science process skills and science attitude, as science educators have indicated. For this study, two classes of $5^{th}$ grade students were chosen in the same elementary school. Subjects were divided into an experimental and a control group. The students in the experimental group took part in a science writing program for 14 lessons of science classes. The students in the control group were taught according to the traditional science program using standard science textbooks. To identify the effects of science writing, both groups' students were tested on science achievement, science process skills, and science attitude before the program implementation and were tested on science concept, science process skills, science attitude after the program implementation. The results of this study showed that the experimental group gains significantly higher scores than the control group in science concept and science attitude, but there was no significant difference on science process skills for either group. In conclusion, science writing had positive effects on science concept and science attitude of elementary school students, helping them to express their thinking logically and systematically, but science process skills were not affected.

This study aims to investigate the disparity between the teacher's perception of student-centered inquiry classes and the actual implementation of such practices. Specifically, we compared an elementary science teacher's self-perception of her science lessons with the observers' evaluation using the Reformed Teaching Observation Protocol (RTOP) of the "Temperature and Heat" unit. Research data were collected through classroom teaching survey, interview, and science lessons video which were analyzed using the RTOP. As a result of the study, the teacher recognized that she was practicing inquiry-oriented/student-centered classes, but the results judged by the RTOP score were found to be transitional/student-affected classes by a slight difference. Teacher H planned and practiced classes based on a high understanding and content knowledge of the curriculum and created a science classroom culture that promotes active interaction among students as well as students and teachers. However, teacher-led aspects were still emphasized in teaching design and implementation, and the project theme and content were inappropriate to improve the quality of students' science inquiry experience. In the end, the slight difference between teacher's perception of inquiry-oriented/student-centered classes and actual implementation is related to how student-centered "lesson design" is and how to plan and implement classes supported by "procedural knowledge" for students' experience in the science inquiry process. These results indicate that the teacher's self-evaluation alone is not enough to determine whether the teacher's intentions and efforts are actually being implemented, and that it is necessary to conduct objective analysis, evaluation, and discuss the results of science classes by the external observers.

This study purposes to historical approach the formation process of Nature-Study, and to re-evaluate its definition and direction at present. The idea of Nature-Study originated from Campanella, Ratke and Comenius, who emphasized real things. The idea developed through Object Lessons of Sheldon, the Natural History of Agassiz, and Progressivism of Parker. They acted as the main contributors who evolved the idea of Nature-Study and its core fields that involve: 'studying with real things' in Object Lessons which brought the methodical aspects to the idea, 'studying with nature' from Natural History that enhanced the content characteristics and 'learner-centered education' from Progressivism, which impacted the philosophical aspects. Straight (a fellow student of Agassiz) was a teacher for Sheldon Oswego normal school and Parker's Cook County normal school, who synthesized the fields together and paved the way for the formation of Nature-Study. Jackman of Cook Country normal school established Nature-Study as a school curriculum and Bailey and Comstock of Cornell University formed the American Nature-Study Society and as a result, Nature-Study started to gain popularity. However, many educators increasingly rejected Nature-Study as a unifying topic, and preferred the use of textbooks rather than firsthand experiences. This hindered the nature-study movement and it declined since the 1920s. But today, the Nature-study idea can play a huge role in developing science education, inclusive education centered nature, self-initiated retrieval, sympathy with nature and character building of students.

The purpose of this study was to investigate the effect of metacognitive strategy on conceptual acquisition ofvseasonal change and self-efficacy when it was applied to 6th grade elementary students. This study consists of 2 classes, 76 students in the 6th grade of elementary school, which were divided into the experimental group (38) and the control group (38). First, a pre-test was administrated to check students' levels of metacognitive self-regulation and self-efficacy prior to getting planned lessons and then an instruction program was developed based upon the metacognitive instruction model and students' conception. The control group was exposed to traditional methods mainly using the textbook and teacher's guide book. The experimental group employed a metacognitive learning strategy program and activities with metacognitive questionnaires. After the planned lessons, the students were tested with post-tests about the conception of seasonal change and self-efficacy. One month later the students were tested again with another test to determine the continuation effect. The results were as follows: First, the group that used metacognitive conceptual change instruction did better in forming and continuing to maintain the scientific seasonal change conceptions compared to the control group. Second, the high and intermediate group taught by metacognitive conceptual change instruction was higher in the level of self-regulation than the control group. However, it was not verified in the low group. Third, the group which used metacognitive conceptual change instruction showed a higher level of self-efficacy than the control group did.

Math classes has been regarded as an independent area of a teacher and his/her students of a particular class. In Recent discussions about the professional development of teachers, for the improvement of practices, the point of view of that the community of teachers must work together is spreading. What are the considerations in organization and operation of learning communities for professional development of teachers? In this study, we analyzed the case of the learning community of math teachers in a Science Academy for the purpose of improving math classes to promote the participation of learners. Research results show that teachers share the principles and goals of mathematics teaching through the learning community. Also, through participation in learning communities, the members were practicing the lessons improved by reflection on the lessons of his/her and their colleagues. These results provide implication that it is important to provide opportunities for objectifying his/her classes through the learning community for a substantial improvement in math classes.

The purpose of this study was to examine the management status of science in senior high schools based on the 2009 Curriculum Revision and the science teachers' perception of the content and a class of science. The way of managing a class was surveyed and discovered that the percentage of more than two teachers giving lessons depending on their major was higher than that of a teacher giving all the lessons. Analysis of teachers' perceptions of the content of science showed that science textbooks reflected the revised science curriculum well. However, teachers thought that the terms and concepts introduced to describe the knowledge of frontier science were so difficult that they feel it's very hard teaching them to the students. Even though science teachers thought that science was mainly focused on cultivating scientific literacy of the students, they assess mostly understanding of science concepts on the students. It means that science teachers stay in line with old position in assessment.

The purpose of this study is to investigate beginning secondary science teachers' teaching practices in terms of motivating and understanding students. Six first-year teachers participated in this study. Data were collected by classroom observations and structured interviews. Instructional materials used during the class were also collected to understand teaching practice. Lessons observed were video-tape recorded and the teachers were interviewed. Video- and audio-tape recording were transcribed. The framework, developed by Knowles Project Team of Michigan State University, was adopted and revised according to Korean classroom context and employed as an analytical tool for teaching practices. The beginning secondary science teachers intention ranged from 'Managing Work' to 'School Science.' No teachers revealed 'Reform Science Teaching' orientation. For the execution of science lessons, one teacher with 'Managing Work' orientation showed 'expert' level of execution, but the others executed at a 'novice' level. Beginning science teachers need to be guided and informed about 'Reform Science Teaching' for motivating and understanding students to develop professionally.
