The purpose of this study is to investigate the degree of concept understanding on the stratum for elementary school students. For this objective, questions on the stratum concept were developed, and concept survey was conducted for random sampling of $5^{th}$ and $6^{th}$ grade 536 students. As a result, students chosen correct answers of the average 57.4% for 16 questions. Below the average rate of correct answers in each domain were 1 question in the definition of the stratum, 3 questions in formation of the stratum, and 4 questions in features of the stratum. Especially, the percentage of correct answers were appeared in lowly that the difference between the visible side and non visible side on the stratum, the definition and formation process of a fault and the main cause of the stratum's exposure. Also, between the residence, grade, and gender of students, there were significant differences in 2 questions, 7 questions, and 1 questions, respectively. Therefore, many elementary school students do not have high understanding about the stratum concept. Through the results of this study, it can be contributed to find an efficient ways as a basic data for modify misconceptions of the stratum to the scientific concept.

Students' engagement is important for meaningful learning and it has multifaceted aspects for their science learning. This study investigated elementary students' perceptions of science learning engagement. The subjects of this study were 341 4^th to 6^th elementary students. The survey questionnaires were 5-Likert scale questions and free response questions on science learning engagement. The results showed that elementary students' perceptions of behavioral engagement were higher than emotional and cognitive engagement. Keyword network analysis with NetMiner program showed that the frequent key words of science learning engagement were 'experiment', 'listening', and 'teachers' explanation', which were mostly the behavioral types of engagement. The degree centrality and eigenvector centrality of these key words appeared high. 'Interest', which is emotional engagement, were also one of the frequent key words, but the centralities of this word were relatively low. The Frequent key words of science learning disengagement were mostly related with off-tasks, not doing expected behaviors and negative emotions about science and science learning. Educational implications on science learning engagement were discussed.

In this study, we investigated the effects of explicit instruction about nature of science by elementary school students' cognitive level. Participants were six classes, 187 sixth graders at elementary schools in Daegu. Three classes were assigned to control groups and the other classes to treatment groups. Control groups were provided normal instructions and treatment groups were provided instructions integrated with nature of science about chapter 'electromagnet' for 9 class periods. The results of this study were as follow. Both low-cognitive level students and high-cognitive level students in the treatment groups are improved in understanding about nature of science by the explicit instructions about nature of science. Especially, the high-cognitive level students had more improvement than the low-cognitive level students in understanding about nature of science by the explicit instructions about nature of science. There were no significant differences between the test scores of the two groups in the science interest sub-domain of the science-related affective domain. But, there were significant differences between the test scores of the two groups in curiosity and open-mindedness of the scientific attitudes sub-domain of the science-related affective domain.

The purpose of this study is to examine the efforts of cooperative loaming through a student team-achievement division(STAD) model on elementary school students' learning achievements and science ,elated attitudes toward the field of astronomy. This study was conducted using 72 students of the fifth-grade class in a elementary school in Busan. The 18 science lessons of the 'Family of the sun' were executed over 6 weeks in the fifth-year students classes. In this study, the experimental group were exposed to cooperative learning through STAD and the contrast group were exposed to a traditional teacher-centered class. The results show that the STAD class of the experimental group had a greater effect upon the elementary school students' science learning achievement and science related attitudes toward the field of astronomy than those of the comparison group. Additionally, the students recognized that cooperative learning provokes both interest in loaming and in their studies generally and also they expressed a desire to continue with cooperative teaming methods.

The purpose of this study was to develop MBL(Microcomputer Based Laboratory) programs for sixth-grade elementary students in science laboratory instructions and to ascertain the effects of this program on academic achievement and science-related affective characteristics. In laboratory instructions, using the MBL was found to be effective in improving academic achievement for elementary students, especially in the domain of knowledge. In addition, it helped students to improve science-related affective characteristics. The experimental group showed higher levels, especially in the domains of cognition and interest. When our findings were analyzed in detail, the sub-domains that showed positive effects included 'cognition of science' in the domain of cognition, and interest toward science', 'interest toward science learning', 'interest toward science related activities', and 'anxiety for science' in the domain of interest. Male students exhibited improvement in the domain of cognition while female students showed improvement in the domain of interest. In conclusion, utilizing MBL programs as an experimental measurement in the real field of elementary science education can be said to be both positive and desirable.

This purpose of this study was to analyze the characteristics of elementary students' argumentation in science problem solving process. For this study, the two argumentation topics were developed on the basis of Williams and Colomb's argumentation model. The topics of argumentation were the weight of the air and the change of volume according to state of water. The participants of this study were 6th grade students (n=51). Data were analyzed by Williams and Colomb's argumentation model and Kienpointner's argumentation style. The results of this study were as follows: In the argumentation model, most of students had the factors of claim, reason, evidence/data in their statements. But low-achievement students had difficulty in warrant and acknowledge & response. In argumentation style, the frequency of the cause-effect and explanation of example style were higher than other argumentation styles. Some implications were suggested, such as understanding the characteristics of elementary students' argumentation activities and need of educational programs including scientific argumentation.

This study examined the effect of interparental conflict and parent-child conflict on overt aggression in upper elementary school students and investigates if children's father-child conflict or mother-child conflict mediated the effect of interparental conflict on overt aggression. The participants of this study were 532 of fifth to sixth graders from three elementary schools located in Seoul and Gyeong-gi province. Participants were asked to respond to a written questionnaire to measure research variables of the Peer Conflict Scale, the Conflict Tactics Scales, and the Conflict Behavior Questionnaire. Data were analyzed by descriptive statistics and hierarchical multiple regression. Mediating effects were examined using analysis procedures of Baron and Kenny. The major findings were as follows: first, the level of interparental conflict and parent-child conflict of both mothers and fathers in upper elementary school students increased the level of overt aggression. Second, parent-child conflict of both mothers and fathers in upper elementary school students partially mediated the relation between interparental conflict and overt aggression. Higher levels of interparental conflict resulted in higher levels of parent-child conflict, and the subsequently higher frequency of overt aggression in upper elementary school students.

This study investigated elementary students' perception of the suitability of inquiry activities related to the science inquiry, essential features of the inquiry and essential features of the inquiry by science inquiry activities. First, 5-6th grade elementary students' perception of the suitability of inquiry activities to the science inquiry was positive in this study and especially the score of experiment and field trip was high. The lowest score was on the discussion and elementary students thought that discussion might be wrong, because they just talked when they participated in the discussion. Second, perception of the essential features of science inquiry was positive. Especially, engaging students in evaluating their explanations in the light of alternative explanations was the highest. Students thought that explanation is important, but it is too hard to perform the science inquiry with only the explanation. Third, the score of research and experiment was high in essential features of science inquiry by science inquiry activities. The score of the field trip was low, so a more meaningful field trip should be carried out in the school.

The purpose of this study was to explore the possibility of implementing 'responsive teaching (RT)' in elementary school science classrooms. A review of relevant literature yielded a tentative framework of RT which consisted of three characteristics of RT and example practices for each characteristic. The RT framework was used to analyze elementary science lessons on the topic of the transpiration in plant leaves. The data sources were audio recordings of three $5^{th}$ grade classrooms which included both the whole-class instruction and student group activities. The data were examined through collaboration between the teacher who had taught the lessons and a university-based science education researcher. It was revealed that the implementation of RT was limited when the teacher's intervention was focused on completing tasks; when it was out of the contexts of student activities; when the teacher provided earlier what students were supposed to find out by themselves; and when the teacher's comments were evaluation-centered. By contrast, the implementation of RT was made highly possible when the teacher's intervention induced an intellectual debate among students; when the teacher negotiated meanings with students; when the teacher connected what students shared to scientific knowledge; and when the teacher prompted students to solve a new problem. Implications about implementing and studying RT were discussed.
