This study examines the propositional connections and markers for connecting propositions in the texts of the 3^rd- and 6^th-grade science textbooks developed under the 2015 Revised Science Curriculum. A selection of texts from Korean and social science textbooks were analyzed and compared to those from science textbooks as well. The propositional connections were classified into emphasis, elaboration, exemplification, listing, addition, order, correspondence, causal relation, condition, and purpose types. The markers for the relationship of propositions were classified as demonstrative, using conjunctive, using a comma, using distinctive linguistic elements, and no marker types. The results showed that the frequency of propositional connections in the texts of the 6^th-grade textbooks was lower than that of Korean and/or social science textbooks. However, the frequency of the propositional connections in the texts of the 3^rd-grade textbooks was found to be lower than that of the social science textbook but higher than that of the Korean textbook. The types of order, listing, condition, and causal relation were dominant in science as well as Korean and social science textbooks. Over 40% of the markers for the relationship of propositions were found to be the no marker type, with the ratio of the no marker type being especially higher in the categories of order and causal relation.

The goal of this research is to analyze the trend of Korean fourth grade students' achievement in TIMSS 2011 and TIMSS 2015 science content domains and to suggest implications for science curriculum and teaching & learning improvement. With four elementary science teachers and three science educators, we analyzed Korean fourth grade students' percentage of correct responses in TIMSS 2015 science content and cognitive domains, and conducted item-curriculum matching analysis for test items. According to the results, Korean students performed relatively better in test topics covered in the science curriculum for 3-4 grades regardless of the science content domain (i.e., Life science, Physical science, or Earth science). Korean students showed low percentage of correct answers for items related to such topics as heat conduction, the action of electricity, the motion of the earth and the moon, etc., which were covered in the 5th-6th grades in the 2009 revised curriculum. For science cognitive domains, Korean students' achievement dropped significantly in reasoning between TIMSS 2011 and TIMSS 2015. Discussed in the conclusion are implications to reconstruct elementary school science curriculum, and ways to improve science teaching and learning.

As the age in which the importance of sensitivity has increased, education for the future generation regarding emotion engineering, affective recognition and cognitive science have taken center stage. We measure human's emotion quantitatively, analyze evaluation and apply them to various services in life, which are based on human technology. Therefore, we need the education which is related to emotion science to cultivate talented people. The goal of this paper is to suggest the possibility of emotion science education and effective methods through development of the STEAM (Science, Technology, Engineering, Arts, Mathematics) program which can teach emotion science to early elementary school students by applying it to pilot classes. For this study, first, we build a program, 'The mind made by figure' for student of early elementary school. The method of STEAM was used in this program, because it is an effective system to educate the emotion science. We recognize the needs and value of this program development through theory and benchmarking of STEAM related to emotion science. And then the contents of class, activities, course book and kit are designed with elementary school textbook of pertinent grade. Secondly, we analyze the result which is applied in two pilot classes of second grade by satisfaction survey and teacher interview. As a result, the average of satisfaction level was very high (4.40/5), Class participation was especially high. Third, we discuss the ability, value and limits of this program based on the result of analysis. The outcome of this research shows that students of early elementary school who have difficulty in understanding science can approach the education program related to emotion science with ease and interest. We hope this education will help students understand emotion science effectively, and to train people to lead the emotion centered era.

The study used cross-lagged path modeling to examine the longitudinal associations between self-esteem and community spirit among adolescents. This is a longitudinal study designed to examine the developmental changes of adolescents' self-esteem and community spirit in Korea. This study used the data collected by the Korean Children and Youth Panel Survey (KCYPS) from 2014 through 2016. Participants were surveyed from the 5^th grade to the 7^th, which belonged to the 1^st elementary school cohort panel of the KCYPS. To be used as the data of this study, children should have all information at 3-time points: the 5^th grade; 6^th grade; 7^th grade. The collected data were analyzed with PSAW 18.0 and AMOS statistical program. The participants in this study were 903 males (51.6%) and 847 females (48.4%). The level of self-esteem was 3.29±.51, 3.19±.55, and 3.15±.57 point at 5^th grade, 6^th grade, and 7^th grade each. The level of community spirit was 3.12±.52, 3.09±.59, 3.15±.55 point respectively. Community spirit from elementary school to middle school is consistently predicted by previous self-esteem. Likewise self-esteem has a significant predictive effect on subsequent community spirit.

Among the measurement attributes included in the elementary school mathematics curriculum, perimeter, area, volume and surface area are intensively covered in fifth and sixth graders. However, not much is known about the level of student performance and difficulties in this area. The purpose of this study is to examine the understanding and performance of sixth-grade elementary school students on some ideas of measurement and ultimately to give some suggestions for teaching measurement and the development of mathematics textbooks. For this, diagnosis questions were developed in relation to the following parts: measurement of perimeter and area of plane figure, measurement of surface area and volume of solid figure, and the relationships between perimeter and area, and the relationships between surface area and volume. The performances of 95 sixth graders were analyzed for this study. The results showed children's low performance in the measurement area, especially measurement of perimeter and surface area, and relationship of the measurement concepts. Finally, we proposed the introduction order of the measurement concepts and what should be put more emphasis on teaching measurement. Specifically, it suggested that we consider placing a less demanding concept first, such as the area and volume, and dealing more heavily with burdensome tasks such as the perimeter and surface area.

This study aimed to develop, implement, and evaluate a practical, problem-based global citizenship education (GCED) program in the first grade of elementary school to suggest ways for practical global citizenship education in the next curriculum. This study proceeded following the ADDIE teaching design model. Through literature research, the relevance of global citizenship education to the 2022 national curriculum and the 2022 practical arts curriculum was analyzed, and based on the results, the learning elements of global citizenship education were extracted from the 2022 integrated subjects curriculum to develop the program. The program consisted of four teaching and learning plans for a total of eight sessions based on four practical problems, and was revised and supplemented through validation by a group of experts. The developed teaching and learning curriculum was implemented in all eight sessions over a period of four weeks with 16 first grade students at S Elementary School in Seoul. As a result of the program implementation, the mean of students' global citizenship awareness increased by 3.88 points (±3.91) from pre to post, and the qualitative evaluation of teachers' reflection journals and students' portfolios showed that the program influenced students to realize the importance of taking action to create a better and more sustainable world. Therefore, the practical problem-based global citizenship education program for first graders was found to be effective in fostering global citizenship awareness.

The purpose of this study was to analyze epistemological beliefs in science as perceived by elementary school students and to examine the purpose of science, the nature of scientific knowledge, the source of scientific knowledge, and the role of experimentation. The subjects of this study were 99 elementary school students. As a tool for examining epistemological beliefs in science, we used adapted questionnaires comprising elements constituting epistemological beliefs, as proposed by Elder (1999). The results of the analysis are as follows: First, in terms of the purpose of science, sixth graders had the most modern beliefs compared to other grades. Second, a statistical significance was found between fourth graders and students in other grades based on the analysis of the nature of scientific knowledge. Third, there was no significant difference in each grade's beliefs concerning the source of scientific knowledge or the role of the experiment.

This study aims to analyze mathematically gifted students' characteristics of generalization and justification for a given mathematical task and induce didactical implications for individual teaching methods by students' learning styles. To do this, we identified the learning styles of three mathematically gifted 6th graders and observed their processes in solving a given problem. Paper-pencil environment as well as dynamic geometrical environment using Geogebra were provided for three students respectively. We collected and analyzed qualitatively the research data such as the students' activity sheets, the students' records in Geogebra, our observation reports about the processes of generalization and justification, and the records of interview. The results of analysis show that the types of the students' generalization are various while the level of their justifications is identical. Futhermore, their preference of learning environment is also distinguished. Based on the results of analysis, we induced some implications for individual teaching for mathematically gifted students by learning styles.

This study explored the effectiveness of the online English learning program contents for elementary school students. The study used the online English learning program served by Gyeonggi province office of education. 107 students attending P elementary school in K city volunteered for the program. After studying English via the website for almost one year, they were asked to respond the questionnaires related to the contents of the online English program. Since the research investigated that the relations of students' grades, the time for the study, their diagnostic test scores, and the effectiveness of the contents, the survey responses were analyzed with Spearman correlation. As a result, older students thought that the type of problem-solving, the type of performing a task, WBI (Web Based Instruction) were not efficacious. Also, these types of online English program were chosen as ineffective from the students at the higher level. Whereas the type of private lesson, the lessons based on a story, and the type of animation were preferred to the students who spent longer time on the website. This highlights the need to consider the students' characteristics such as students' grades, the time for the study, and their English level when developing the contents of the online English learning program.
