The purpose of this study is to analyze the field of Earth science at a science fair. For this purpose, 566 pieces of data spanning 21 years (2000 to 2020), acquired from entries in the Earth Science section on the science fair website, were analyzed using the semantic network method. As a result, geoscience topics have been actively explored in works submitted for the Earth Science section of the science fair. Fossils from the Cretaceous period of the Mesozoic Era were particularly predominant. Together with these, keywords corresponding to astronomy, space science, and atmospheric science formed a small-scale network. Astronomy and space science mainly dealt with the dynamic characteristics of asteroids, Venus, and Jupiter. Other subjects included the solar system, sunspots, and lunar phases. Atmospheric science has focused on atmospheric physics, atmospheric observation and analysis technology, atmospheric dynamics, air quality monitoring, while marine science has been limited to physical oceanography and geologic oceanography. This study, is expected to help select Earth Science topics and conduct inquiry activities in schools.

Recently, there has been a dramatic increase in the number of cases that have formed and operated teachers' learning communities through cross-curricular consulting at the school level. The purpose of this study is to explore cross-curricular instructional consulting as an activity of teachers' learning communities at the school level, and investigate the effect of cross-curricular instructional consulting on middle school science teaching. We analyzed features and limitations of cross-curricular instructional consulting revealed in three case studies in middle school, including open classes and instructional consulting sessions, and conducted additional instructional consulting on the same videotaped science classes with science experts from outside. According to the results, science inquiry experiments are often replaced with text reading and interpreting, students' misconceptions and exact scientific representations are ignored, and the goal setting as well as class coverage has been questionable and disputable in science classes resulted from cross-curricular instructional consulting. Discussed in the conclusion are the necessity of cross-curricular instructional consulting in middle school, and ways to overcome limitations of the method of cross-curricular instructional consulting, including alternatives to a praise-only policy in cross-curricular instructional consulting, ways to use cross-curricular instructional consulting without compromising the subject's essence, and ways to improve the undue authority of consultants.

In order to enhance scientific interest and a sense of affinity about ocean, the programs of the oceanic camp 'oceanic summer school' were developed and applied to $4^{th}$ and $9^{th}$-grade elementary and middle school students for 9 years from 2004 to 2012. It was composed of oceanic training for snorkeling, a tour to oceanic institutes and museums near the camp academy place, experimental learning in oceanic-related field, field trips for ocean and earth sciences, and lectures on various subjects of ocean. We developed and implemented 9-kinds of inquiry surveys to evaluate changes in cognitive and affective characteristics, and ocean literacy of students participated at the present oceanic summer camp. Based on the statistical analysis, affective characteristics such as interest, inquisitiveness, passion, and so on, were enhanced. Analysis of ocean literacy revealed that cognitive characteristics of the students were increased by 40%. We presented parents' responses on the programs of oceanic summer school. Some students with less initial interest of ocean have positively changed to make up their minds to be a oceanographer in several years later. In light of this, the summer school can be evaluated to be successfully functioned as a long-term support system for potentially young-talented students in the field of ocean science. This study addresses that long-term implementation of the summer oceanic camp may trigger students with potential talent toward in-depth science in the near future even though it could not bring positive effect immediately. This addresses the necessity of policy supports in order that various programs like the scientific camp should be more constructively developed and executed for next-generation manpower in oceanographic fields.

The purpose of this study was to compare the written tests of the science lessons at elementary schools with the instructional objectives of the teachers' guide for the first term of the 5th grade by using Klopfer's taxonomic system. In the analysis of the instructional objectives in the teachers' guide, A.0(40.0%) and $B.0{\sim}E.0$(42.4%) showed high level but the proportion of processes of F.0(5.6%), G.0(4.0%), H.0(4.0%), and I.0(4.0%) showed low level, while in the written tests A.0 was 54.8%, $B.0{\sim}E.0$ was 36.1%, F.0 was 7.3%, and G.0 was 1.8% but H.0 and 1.0 was not taken at all. In the comparison with the instructional objectives in the teachers' guide about the domain of the knowledge and the comprehension showed hish and the processes of the scientific inquiry showed relatively low. The results of this study suggested that a desirable written test should be made to consider elementary science curriculum and instructional objectives and hold up rates of each behavior category between the instructional objectives of teachers guide and assessment objectives of written tests.

This study investigates the integration of astronomy-related topics in the Korean national science curricula spanning from 1945 to 2023. We analyze the placement and extent of astronomy content across different school levels. Astronomy contents in the science curricula have changed in response to social needs (e.g., practical knowledge required for agriculture and fishery) and advancement in astronomical research (e.g., the discovery of exoplanets and the suggestion of new cosmological parameters). Contents addressing the motions of celestial objects and stellar physical properties have remained relatively consistent. In the latest 2022 revised national curriculum, scheduled for implementation in 2024, several elements, such as coordinate systems, have been removed, while the inquiry activities using digital tools are emphasized. The incorporation of the cosmic perspectives in the national curriculum, as well as astronomy education within the context of education for sustainable development, remains limited even in the most recent curriculum. For future life revisions, the active participation of researchers is needed to reflect the latest astronomical research progress and scientific characteristics in the field of astronomy.

This study investigated the literature about science process skills' evaluation to analyse transition of evaluation objectives before and after a Scholastic Ability Test for College Entrance. In the literature survey the researcher established a 3 dimensional science assessment framework with X axis as science concept, Y axis as science process skills and Z axis as problem context. In order to analysis and compare each items the researcher selected 210 items from the 1st to the 7th trials and 138 items from the 1st to 4th Scholastic Ability Test for College Entrance and sampled 2873 science achievement test items from 10 high schools. In accordance with this taxonomy the researcher analysed and compared science process skills item forms. The following results were drawn : The items were evenly distributed in all the four areas(Earth Science, Biology, Physics and Chemistry) of the science concept domain, but they were heavily concentrated on data analysis and drawing a conclusion in science process domain. In the domain of problem context school context was the majority. In spite of distribution like this the ratio on science process skills measurement items and science achievement test items was increased after the Scholastic Ability Test for College Entrance was given. Also the ratio on item expression type was increased. Item form was almost 5 options selection type in the national level test. Although there were 4 options selection type, 5 options selection type, short answer type, essay type in school level test, rising from 33.1% to 65.5% on 5 options selection type is exhibited. This study showed that the school level item form was better various than the nation level. This point like this is the evidence for the improvement toward the science process skills test and influenced by Scholastic Ability Test for College Entrance. The ratio on the item which joined with the 3 axes had a mean of 99.3% in nation level test and mean 44.9% in school achievement test level. But the ratio in the school achievement test level increased after the Scholastic Ability Test for College Entrance was given. In view of this study we must furthermore study the item types which can evaluate valjdately science process skill's five stage each and evaluation method by the high school students' problem solving patterns and features in scientific inquiry on all science process skills elements.

This study aims to determine the implications of the efficient and effective implementation of science core competency (ScC) education by examining the state of science core competencies derived from the 2015 revised elementary school science curriculum and analyzing teachers' and students' perceptions. To this end, this paper investigated the reality of reflecting the science core competencies of science textbooks in a group of third and fourth graders from seven elementary schools who passed the test. In addition, in-depth interviews were conducted with four elementary school teachers who participated in qualification textbook selection, and 156 elementary school students were surveyed to determine their perceptions of science core competencies. Findings showed that, first, 1,586 science core competencies were reflected throughout the textbooks, with an average of 227 per textbook and biology being the most salient area. Second, teachers did not understand the difference between previous inquiry activities in textbooks and ScC education. Third, no statistically significant differences were observed in the perceptions of male and female students on science core competencies, the highest average of perceptions being those of scientific thinking ability. From these results, this study concluded that for ScC education to be realized as a curriculum, textbooks must be organized according to the purpose of core competency education, implementing practical changes, and efforts must be directed toward changing the perceptions of individuals who deliver education.

The importance of science attitudes is more increasing in science education. Science attitudes may influence students' attainment, consistency and quality of classwork as well as their later views of science education and scientific occupations. According to the international comparative researches and longitudinal studies on Korean students' science attitudes, it has shown that the more grade, the less science attitude. This research was survey the science attitudes and learning environment variables, and then make a inquiry that causes of decline of science attitudes. To study this purpose, the participating students in this study will be selected from 3th to 11th grade. 6,925 participants were administered 3 times in questionnaires of science attitudes and learning environment variables during a year. The result of this study showed that science attitude got low after June. Science attitude was changed from 4th grade to 8th grade students. Science attitude much more decrease second semester than first semester, high school students' science attitude fell much. It was experience about science that cause the biggest effect in science attitude and other learning environment variables influence in science attitude change. Learning environment variables made different influence from students of increased and declined science attitude. As category that influence in science attitude, in elementary school were gender, area and grade, in middle school were grade and area, and in high school was area.

In order to investigate the trends in science education research using AR (Augmented Reality) and derive implications for elementary science education, we analyzed 71 research articles on AR application in science education published in both Korea and abroad from 2010 to August 2020. In quantitative aspects, the number of published articles has steadily increased. For domestic researches, the number of papers targeting for elementary school students was higher than that of middle & high school students. In the research method aspects, qualitative methods were most frequently used. In particular, papers regarding the development of AR program and verification of its effectiveness were most frequently published. The researches using mixed method in domestic field were smaller in number than that of the research in abroad. There were similar trends in research targeting elementary school students. In the aspects of the contents, more researches were performed on biology and earth science areas than others. In case of researches for elementary school students, the proportion of researches on biology and earth science was even higher. Domestically the proportion of studies on the convergence of science and non-science subjects was higher than that of foreign studies. The number of researches exploring the effectiveness on 'non-scientific attitude domain', 'cognitive domain', and 'program domain' were relatively higher than that on 'inquiry & practice domain' and 'science-related attitude domain'. For types of AR contents, 'observation manipulation type' was mostly studied, followed by 'experimental activity type', and 'learning guide type'. In case of studies on elementary school students, the ratio of 'observation manipulation type' contents was higher than that of others, whereas studies on 'field problem solving type' were relatively less reported than others. In addition, studies on 'simple interaction' were most frequently reported. Particularly, there were relatively few studies on 'linear and nonlinear interactions' in domestic field. As a result of analyzing key words, we found that the key words related to the characteristics and implementation of AR frequently occurred, and the key words related to elementary education and the merits of AR had many direct connections with other key words.

The purpose of this study is to explore the teaching and learning experiences to improve the positive experiences about science (PES) of scientifically-gifted elementary school students. For this study, 36 students in grades 5~6 at a gifted science education institutes in Seoul were selected and conducted pre-test and post-test for 'Test for Indicators of Positive Experiences about Science (TIPES).' After the weekly science classes of the institutions were over, individual in-depth interviews were also conducted with some students to explore the teaching and learning experiences for improving their PES. The analysis of the results reveals that the science classes for scientifically-gifted students have been shown to improve PES of scientifically-gifted elementary school students. The teaching and learning experiences to improve their PES included eight teaching and learning experiences that appeared in general elementary school students of previous study such as 'practice-centered exploratory activities,' 'student-led class,' 'positive and professional feedback,' 'construction of knowledge through exploration,' 'class considering student's interest and aptitude,' 'use of materials related to real life,' 'smooth communication and collaboration in group activities,' and 'appropriate difficulty in learning content.' There were also six teaching and learning experiences that newly emerged from science-gifted students: 'Learning experience through the strategies for improving scientific creativity,' 'inquiry experience as a little scientist,' 'advanced or accelerated learning experience,' 'learning experience with excellent students,' 'experience helping other students,' and 'experience with high or low achievement'. Based on these results, the practical implications for improving the student's PES are suggested.
