Flipped learning can be used as an innovative teaching method in science education. This study analyzes video clip produced by pre-service elementary school teachers for flipped learning and explore strategies to organize effective visualization. The pre-service elementary school teachers focused on providing information on macroscopic natural phenomenon using concrete case selection strategy for earth science class. They used marker and spatial transformation elements effectively, but their efforts to link the elements to the experience of students were not sufficient. In addition, it was very rare to put the contents into simplified drawing or provide extreme cases to enhance the imagery of students. In addition, it is necessary to provide specific case of multi-modal and link the material to the experience of students closely through familiar cases or analogical model to establish an effective visual teaching material. It may also be needed to present simplified drawing for enhancing imagery and provide extreme cases to make students have an opportunity to infer a new situation.

Interest and importance about science attitude are increasing. Science attitudes may influence on students' attainment, consistency and quality of classwork as well as their later views of science education and scientific occupations. This study performed qualitative analysis of the variables that influence on their change of science attitude. To serve the purpose, the participating students in this study were selected from 4th to 6th grade. Interview was administrated to 33 elementary students. The result of this study showed that many science activities or experiments must help students to have positive science attitudes. Science teacher's role is definite and science experience. teacher, classroom climate, and friends influenced on science attitude change. Thinking the results of the present study, it is expected to continue additional research about whether science attitude is influenced on these variables.

The purpose of this study was to explore the elementary school teachers' perceptions about making a model of volcanic activity. Thirty elementary teachers participated in the study after they in which they conducted the experiment of "Making a Model of Volcanic activity". A questionnaire was used to investigate how the teachers understood the strengths and weaknesses of the experiment in terms of the goals of school science inquiry. The results showed that 50-60% of the teachers were able to conduct the experiment as guided in the textbook regardless of their career or area of concentration. The teachers perceived that the experiment of current textbook was safe and useful for students to develop their creativity. However, they pointed out three major weaknesses of the textbook experiment: First, the textbook experiment does not clearly present the main purpose of the activity. Second, it does not appropriately reflect the natural volcanic activity. Third, it is a merely simple craft activity. In addition, the teachers agreed that the main goals of school science inquiry are the application of scientific knowledge, development of inquiry skills and cultivation of student's curiosity. However, the teachers perceived that the experiment of current textbook did not meet these three goals. They suggest that the experiment reflect the nature of real volcanic activities.

Frequently, pre-service elementary teachers are asked to write reflective journals on their teaching during teacher education program. However, writing reflective journals can not guarantee pre-service teachers to learn from their experience. In this study, 44 reflective journals of pre-service elementary teachers on their science teaching were analyzed in terms of 'productive reflection', a concept suggested by Davis (2006). Productive reflection may help teachers' effective learning by considering interrelationships among aspects of teaching including learners and learning, subject matter knowledge, assessment, and instruction. The result showed what aspects of teaching were included, emphasized, and integrated in the pre-service elementary teachers' reflective journals. Implications for teacher education would be discussed.

The purpose of this study was to investigate the changes in teachers' recognition of science class and children for the gifted, and the process of changes in their practical knowledge after the experience of science class and conversation with colleague teachers. Two elementary teachers, teacher A and B, were selected as subject of investigation, who wanted to improve their science class. They experienced the process of self-examination during their class and from class conversations. Teacher A has 10 years of teaching experience. She has been in contact with gifted children and observed them since undergraduate. She entered the graduate school since she came to be interested in science class and children for the gifted. While teacher B has only three years of teaching experience and had a first contact with the gifted after graduate school. The results of this study are as follows. Teacher A didn't change recognition of gifted children class by class conversation in short term because she had a firm faith in good class teaching and was rich in class teaching knowledge. And, her practical knowledge was applied to the next class by changing teaching method or by supplementing her class contents in concerned part through class observation and class conversation with her colleagues. Teacher B was characterized as being lack of class confidence and concerned more about subject knowledge. She was forming a new practical knowledge along with new class teaching knowledge. Teacher B was in trouble with applying new practical knowledge to next class. From such findings, it was concluded that the process of changing or forming of practical knowledge depends on the beliefs, values, experiences, or knowledges of each teacher. A reflection on one' own class teaching could be a good way to form a practical knowledge and improve teaching speciality, when it was concerned with self-reflection of their own class, class observation, and communication with colleagues. Thus, the reflection practice could be applied to the teaching program of teachers for the gifted to form practical knowledge through trial class, self-reflection of class, and conversation with colleagues.

The purpose of this study was to investigate the preferred SSI topics of students and teachers in elementary, middle, and high schools. It analyzed the similarity of students' and teachers' preferred SSI topics by school level using the cosine similarity measure. A total of 566 students and 327 teachers from elementary, middle, and high schools participated in the study. Sixty topics were identified and listed in the areas of environment, science and technology, health and medicine, and other social issues based on the literature and SSI programs. Students and teachers were asked to select five of their favorite topics. The data was collected online using SurveyMonkey. The collected data was divided into six groups of students and teachers, and the frequency of topic selection was analyzed within each group. The topic preference similarity was analyzed by calculating vector values based on the frequency of the selected topics and measuring the cosine similarity between students, teachers, and teachers and students by school level. The results are as follows: First, the cosine similarity of SSI Preferred Topics between students' school-level cohorts was higher between middle and high school students (0.982) than between elementary and middle school students (0.651) or between elementary and high school students (0.662). Second, the cosine similarity of SSI Preferred Topics between teachers' school-level cohorts was similar for all comparison groups between elementary, middle, and high school. Third, the SSI topic preference similarity between students and teachers by school level had a higher cosine similarity between the elementary student and teacher cohorts (0.974) than the other school level comparisons, middle school (0.621) or high school (0.645). Access to topics of interest to students in SSI education is strongly associated with motivation and persistence in learning, as well as an enjoyable learning experience and positive attitudes toward learning. Therefore, when designing SSI lessons, it is important to examine topics from the perspective of student interest, especially if the teacher has selected SSI topics that are different from students' preferences. Careful instructional design will be needed to overcome the gap.

This study aims to explore scientific reasoning that students and their teachers constructed in elementary science classroom discourses in terms of basic reasoning types; deduction, induction, and abduction. For this research, data were collected from 13 classes of 4th grade science activities during a period of three months and analyzed three types of scientific reasoning in elementary school science discourses. We found that deduction (one discourse segment), induction (one discourse segment), and deduction-abduction (two discourse segments) were presented in the discourses. They showed that: first, scientific reasoning proceeded explicitly or implicitly in elementary science discourses; second, the students and their teachers have potentials to increase the quality of reasoning depending on their inter-subjectivity; and last, the students' background knowledge were very important in the development of their reasoning. Implication and remarks on science education and research were presented based on this results as well.

이 연구의 목적은 인지적 전략인, 갈등도(Oh, 2011)를 기반으로 학생들이 명시적으로 과학의 본성(NOS)의 교육을 돕기 위하여 과학의 본성요소뿐만 아니라 과학의 역사를 담은 NOS Flow Map을 개발 제안하는 것이다. 예비적으로 과학의 본성의 교육을 위해 제안한 NOS Flow Map을 사용에 대한 이해를 탐색하기 위하여, 자신들의 NOS 이해를 강화하기 위해 우리가 제안한 NOS Flow Map의 유용성에 대한 예비 초등교사들의 인식를 조사하였다. 과학의 본성에 대한 중요한 관점들은 Kuhn의 과학철학과 역사가 아주 잘 일치된다. 즉 Kuhn의 과학혁명의 예로 가장 중요한 Copernicus의 혁명과정이 과학의 본성 중요한 요소들과 잘 일치됨을 보여준다. 따라서 이 연구에서 인지갈등을 통한 NOS 흐름도는 과학의 소양교육을 강화하는데 명시적이고 반성적인 도구이며 유망한 방법이라고 조심스럽게 제안한다.
