The purposes of this study were to analyze high school students' understanding about the Earth system and systems thinking process, and to develop science writing programs designed to assess students' understanding about themes of Earth Science such as global warming, volcanoes, and desertification. A total of 8 $11^{th}$ grade students from general high schools participated in the writing program and draw the causal maps. The methods of this study are as follows. First, DAET-C was used to investigate the way of students' understanding about the Earth systems. What the students' best understood was the component of the Earth systems followed by the interaction of the Earth systems and the scientific literacy of Earth science. Second, feedback circulations on the causal maps were found in four students in global warming section, one student in volcanic eruption section, and four students in desertification section, which means that systems thinking was not largely employed by the students. Consequently, the student participants understood that the global change was happening in correlation with complex concepts and factors, but they were short of using systems thinking in their science study. Therefore, the result of this study suggests that more studies be conducted to develop systems thinking in Earth Science learning through science writing programs.

The purpose of this study is to understand the elementary student's growth and its implications from the students' experience participating in the science fair by phenomenological study. The results are as follows. First, the students have various experiences. They acquire scientific knowledge and inquiry skills by conducting in-depth experiments, visiting several places, and interviewing experts. They have some experience in writing experiment journals to record the inquiry process in their own language, and presenting their results in public. Second, the students suffer several difficulties while preparing for the science fair. They have some difficulties when the results were not consistent with the hypothesis, or they had to repeat the experiment over and over. They feel burdened in writing the experiment journal. They had a few time to meet friends or for hobbies. Third, the students improve scientific attitude through the science fair, and they receive a positive effect on the affective side. They developed scientific interest, curiosity, cooperation, etc. And they also gained a sense of accomplishment, confidence, friendship, good relationship with teachers, career interest, etc. This study finds out that students participating in the science fair have a lot of experience that cannot be done easily in a normal science class. Even though students confront some difficulties in the inquiry process, they make good progression and feel accomplished. So the science fair is valuable experience for them.

The writing brush, ink stick, paper, and ink stone were the four precious things of the studying and recording in oriental world until even nowaday. The oriental paper was comparatively well evaluated in many papers and reviews, but it is difficult to find some scientific reports or reviews about the ink stick. In this paper, the scientific aspect of ink sticks of oriental maine three country(Korea, China, Japan) were evaluated by the physical, chemical and microscopic analysis. The result could summarized as fellows; 1. The Korean lampblack ink stick contains more carbon and less nitrogen and the Chinese ink sticks contain less carbon and more oxygen. 2. The Korean lampblack and cowhide glue contain relatively higher amount of sulphur. 3. The particle size distribution of carbon in the ink stick was not change after grinding in the ink stone. 4. The particle size of carbon and the pore size in the charcoal ink sticks of three country were larger than those of the lampblack ink sticks. 5. The ink solution of the charcoal ink sticks shows high roundness on Hanji while the ink solution of the lampblack ink sticks is spread readily to Hanji surface. 6. The change of whiteness in printing of the ink sticks is notable in thermal treatment.

The study presents preliminary research on how science activities focusing on problem recognition worked and affected students' perception of their learning environment in a sixth science classroom. The science activities were based on the Science Writing Heuristic (SWH) which was suggested by Keys, Hand, Prain & Collins (1999), where problem recognition was an important part of scientific inquiry. For developing the working sheets for the modified SWH in this study, analyses of target units of 6th grade science curriculum in the aspects of problem recognition were conducted. After consecutive 6 classes with the developed working sheets for sixth graders, the student working sheets for each lesson were collected and analyzed. In order to investigate the developed units' affect on student learning, students' perceptions of their learning environment were administered before and after the applied classes. Students working sheets and questionnaires on their perceptions of learning environment indicated that students perceived that the science activities were more student-centered classes where students had active discussion and dialogue with one another giving them more chances to actively take part in the class as well as they used more properly recognized their inquiry problem.

This study plans to develop strategies using children's verse in science education and investigate the effects of instruction using children's verses on the attitude toward science. The study tried to determine strategies using children's science verse in order to find out their value. For the purpose of this, two classes of the 6th grade were selected in an elementary school for tests. The results from this research showed that strategies using children's verse in science education were developed and applied in teaching/learning purposes as well as in the area of literature. A strategy for remembering was applied widely. A strategy for understanding scientific principles and for quest methods, writing children's science verses directly helped in scientific conceptual formation. Instruction using children's science verses had a positive effect on the attitudes toward science. Students maintained positive attitudes throughout instruction that used children's science verses. In conclusion, instruction using children's science verses can be applied to science education, and the attitudes toward science and learning achievements can be improved.

School science practical work is often criticized as lacking key elements of authentic science, such as peer argumentation or debate through which social consensus is obtained. The purpose of this paper is to review the recent studies about the argumentation and to explore the conditions and the model of argumentative scientific inquiry, which is specially designed open inquiry in order to facilitate students' peer argumentation. For this purpose, a theoretical discussion for the argumentative scientific inquiry as the way of authentic inquiry in schools was developed. The conditions for argumentative scientific inquiry were found to be the following: multiple arguments, students' own claims, opportunities for oral and written argumentation, equal status of debaters, and community of cooperative competition. For these conditions, the argumentative scientific inquiry was organized into experiment activities and argumentation activities. During argumentation activity, students should be guided to advance written argumentation through writing a group report for peer review and oral argumentation through a critical discussion. Through the argumentation between groups and in group, the students' arguments would be elaborated repeatedly. The feedback from argumentation links experiment activities to argumentation activities. Hence, the whole process of this inquiry model is circular.

The purposes of this study are to analyze the merits and limits of flipped learning by suggesting the ALP model for efficient application and to test the effects of the new ALP model. The process of new model and program development is based on ADDIE in this study. This study consists of two steps. First through literature research on the difficulties of the flipped learning, the elements are extracted to develop new model. Second, these elements were placed according to the teaching and learning flow, which resulted in the procedures. As a result, the ALP model was developed. The ALP model is a new model for applying teaching and learning methods for efficient application of the flipped learning. This model was applied to elementary science classes to test its effects in scientific communication skill. Interviews and cognitive survey were also conducted to collect additional information. The results of this study are as follows: There were various difficulties in flipped learning. Based on literature research results, the ALP model and the science programs for elementary students have been developed. The experimental group showed statistically meaningful improvement in scientific communication skill. The scientific communication skill has two subcategories: the forms and the types. According to the form analysis results, the experimental group showed a statistically meaningful improvement in the form of Table and Picture, but not in the form of Writing and Number. With the same reason given previously, this study confirmed that the application of ALP model improves the students' visual form communication skills such as Table and Picture better than reading form communication skills such as Writing and Number. According to the type analysis results, the experimental group showed a statistically meaningful improvement in "the scientific insistence" type, and "the justification" which is the sub element of "the scientific insistence" type. With this reason, this study suggests that the class applied ALP model gives students more time and opportunities to learn. Though the survey and interviews about the student's awareness of the class with applied the ALP model, this study showed that students actively exchanged their opinions in the class with applied ALP model.

This research was conducted to investigate the effects under which learner-generated pictorial representation introduced in summary stage of lesson serve as an instructional strategy improving academic achievement and scientific attitude. The subjects of this study were 152 students (experimental group: 38 boys and 39 girls, control group: 36 boys and 39 girls). Using the learner-generated pictorial representation were applied to experimental group, whereas summarizing the lesson in writing to control group. The results of this study were as follows: First, there was no significant difference between the two groups in the post achievement results. But, a statistically significant difference on a delayed post-test of academic achievement was found between experimental and control groups. Second, there was no significant difference between boys and girls in the post achievement test. But a significantly positive effects on the academic achievement was found in boys of experimental group. Third, experimental group scored higher than the control group in all sub-domains of the scientific attitude; curiosity, openness, criticism, cooperativity, willingness, perseverance. Findings suggest the descriptive drawing is a viable way for elementary students to understand scientific concepts and to improve scientific attitude.

This study was designed to explore how learners' participation develop if provided with opportunities for various scientific practices and experiences in writing science magazine articles as an extra-curricular club activity and what factors facilitate these participation development. Data from participant observations, in-depth interviews with students, and documents were used to extract the common characteristics of the practices. The learners' development was categorized into 3 stages in terms of participation in the community of practice: peripheral participation, transitional participation, and full participation. As participation develops, situational interest developed to individual interests and value attachment. Students sought to get ideas from every day life, and finally, in the stage of full participation, advances in writing showed the characteristics of knowledge transformation. Best of all, the participants enjoyed and valued their participation showing identities as journalists. The nature of science magazine article, external scaffolding, and internalization through enjoyment and value attachment appeared to be decisive factors that facilitate the development of participation. Student's enculturation of writing for learning offers a possibility that continue to do so, even after they have left formal schooling and make a basis for lifelong learning.

This study aims to explore patterns and characteristics of coordination between evidence and theories which were found in pre-service elementary teachers' writing for their science inquiry. Five science inquiry activities and a total of 115 writings of the participant teacher at the elementary teacher preparation university in Korea were collected and analyzed for this study. Based on the writing analyses there were found four types of coordination between the evidence and theory. We proposed four types as: Type 1-Consistency of evidence and theory; Type 2-Consistence of evidence and theory including more extension or elaboration of theory; Type 3-Inconsistence of evidence and theory Type 4-Inconsistence of evidence and theory followed by coordination of them. Firstly the findings indicated that the most to least frequent types were Type 1, Type 3, Type 2, and Type 4. The most frequent type was Type 1. It is interpreted that theory in the inquiry questions were frequently figured out by participants and they selected supporting evidence out of data found. There were rarely found relations between activity topics and frequencies of coordination types except in activity 1. The findings in this study will connect to the point of how students collaborate their previously owned knowledge with experiment planning, data analysis and interpretation and making of their own scientific claims.
