  • The purpose of this study is to present a reflective review of the earth and universe units from the revised elementary curriculum of 2007-2015 and suggest changes in the 2022 revised curriculum. For this purpose, we conducted an FGI with earth science educators and elementary school teachers regarding the content elements and system, the achievement standards and inquiry activity composition, and the vertical and horizontal curriculum connectivity. Free response and weighted hierarchical analysis items were incorporated into the FGI to ensure logical consistency of the inductively derived improvement. This analysis revealed that the composition of units by grade group had been unevenly distributed among each of the "earth systems" until the 2015 revised curriculum was finalized. Furthermore, the basic concept was still insufficient. We suggest that achievement standards centered on the learning content and skills must state specific scientific core competencies, and inquiry activities should include rigorous critical thinking, student written responses, and student inquiry and analysis. In the hierarchical analysis items, FGI emphasized the inclusion of essential content elements rather than reduction of content elements, understanding-oriented concept learning rather than interest-centered phenomenon learning, basic concept division learning before integration between subjects, and expanding vertical-horizontal connectivity rather than repeating and advancing learning. There is a limit to the generalizing the suggestions proposed in this study to the common opinion of elementary earth science experts. However, since the main vision of the 2022 revised curriculum is to gather opinions through educational entities' participation in a variety of educational subjects, it is suggested that our results should be incorporated as one of the opinions proposed for the 2022 curriculum revision.

  • This study sought to develop an integrated information literacy curriculum that would have a strong relationship with curricula through the standard themes abstracted from theme network structures, scan and cluster analyses of the information literacy curricula. In addition, this study also attempted to develop a teaching-learning model for the developed integrated information literacy curriculum. This study utilized the themes of information literacy instruction that have interdisciplinary characteristics as analysis criteria in analyzing the commonality of information literacy instruction and the subject curricula. The following characteristics were found from the analyzing the areas of commonality. Foremost, the first themes(the fields of basic learning skills and nature) which belongs to the fields of information society, library, information technology, collaborative skills were found to have many relationships with the subject curricula. Next, the second themes(the field of information problem solving capabilities) which is the core field of information literacy instruction showed a weak relationship with the subject curricula.

  • This study compared the characteristics of scientific poems written by scientifically-gifted and general elementary students, and their perceptions of writing scientific poem. To do this, 5~6 graders (n=100) at two gifted science education institutes and 5~6 graders (n=93) at a elementary school in Seoul were selected. Scientific poems written by the students were analyzed according to their numbers and types. Their perceptions of writing scientific poems were also analyzed through a questionnaire and group interviews. The analysis of the results revealed that the general students wrote more scientific poems than the scientifically-gifted students for thirty minutes. The general students mainly named the titles in a direct way, while scientifically-gifted students did it in an implicit way. The free verse poems in both general students and scientifically-gifted students appeared most frequently, and the prose or narrative poems also often appeared. The general and scientifically-gifted students frequently used impersonation, and some students did not use metaphors. They didn't connect the scientific knowledge for multiple grade. While the poems of the general students evenly included the scientific knowledge for various academic fields, those of scientifically-gifted students tended to include the scientific knowledge for physics or chemistry. The poems of scientifically-gifted students tended to include more science process skills, especially in basic inquiry skills, than those of general students. The scientifically-gifted students wrote scientific poems in a more expanded form regarding the scientific knowledge, than the general students. Scientifically-gifted students perceived the educational benefits of writing scientific poems more positively based on various cognitive and affective aspects. However, many scientifically-gifted and general students had also several difficulties in the processes of writing scientific poems. Educational implications of these findings are discussed.

  • The purpose of this study was to examine the effects of the level-differentiated laboratory activities suggested by the 7th national curricula compared to the in-depth level activities only and supplementary level activities only. Two hundred 7th grade students attending a coed middle school were selected for this study and divided into three groups; level-differentiated, in-depth, and supplementary group. In each group, the students were subdivided into the in-depth level and the supplementary level by the formative test after completing the basic learning course. The in-depth and the supplementary laboratory activities were developed and engaged to the respective students in the level-differentiated group for one semester, while only the in-depth activities were engaged to the in-depth group and only the supplementary activities were engaged to the supplementary group. To examine the effects of treatments, the science knowledge test and the inquiry process skill test were administered before and after treatments and the students' opinions about the level-differentiated instruction were surveyed. The results showed that there were significant differences in the science knowledge achievements between the groups while no significant difference was found in the inquiry process skills. Post hoc analysis showed these differences were found between the level-differentiated group and the supplementary group. After the activities, most students in the level-differentiated group responded positively on doing level-differentiated activities except a few students in the supplementary level, These results justify the effectiveness of the level-differentiated laboratory activities compared to the supplementary only laboratory activities in middle school science classes.

  • The enhancement of inquiry skills has been emphasized as a important objective of science education for a long time. Of these, the observation is not only a simple and basic skill, but also a very important skill, in aspect of gathering informations about the nature of all things around us, through interaction between the sense organs of body and objectives. The purpose of this study is to investigate the results of observations about the grasshopper(Oxya chinesis), made by the elementary student from the 3rd to the 6th grade, and to make use of them as the basic materials for the observative teaming and the evaluation of the observation ability. Through this study, the collected items of observation are as follows For grasshopper, a total of observation items is 95, 70 using the sight sense, 13 using the tactile sense,7 using the olfactory sense. 3 using the palate sense and 2 using the auditory sense. In this study, the findings of elementary student's observation are as follows. 1. On the whole, most of students have observed mainly by the sight and the tactile sense, when observing the grasshopper. 2. It is showed a tendency that the observation ability of student is increased with the higher grade in elementary school. 3. As the grade ascends. the observations with operating are increased, also the quantitative expression and interpretation about them are increased. 4. In the case of same grade, there is no significant difference between students' gender, though girls' ability of the observation showed somewhat higher than boys' 5. Occasionally, the interpretations on the observative facts made by student, are inaccurate. Basis on the above results, we suggested some directions for the improvement of the observative learning program in science classroom of elementary school. First, the teacher have to serve as a guide and encouragement in the observative learning class, to be accomplished the various observation, which all the sensory organ can be used by student than the sight sense. Second, to get elevated the ability of observation, it is necessary that some experimental tools(magnifying lens, stereoscope, auxiliary implements etc.) are utilized. Third, the teacher have to make often endeavors showing an example of operation, to be activated the atmosphere of operative observation.

  • The aims of this study were to classify the cultivation status of medicinal crop farmers and to obtain basic data on domestic medicinal crops. To this end, 406 medicinal crop farmers participating in farming education programs in 14 cities and counties were surveyed over 10 months. The results were as follows. First, the biggest difficulty farmers faced in the overall production of medicinal crops was a lack of cultivation skills. Second, in a detailed inquiry about each difficulty item, the most difficult problems were injury by continuous cropping of root-using crops, shortage of specific farm machinery, uncertain market prices, and lack of knowledge about pest control or the positive list system (PLS). Third, the profitability of medicinal crops increased with career experience. Among the farmers who earned profits, requests for education and technical guidance were the most important factors for profitability. Fourth, the results of the analysis suggest that to achieve stable cultivation of medicinal crops, the following items need to be addressed: development and supply of basic cultivation technologies, climate response, registration of pest control pesticides, a solution to the injury by continuous cropping, and contracting cultivation expansion. Additionally, to improve profitability, it is necessary to create conditions that enable the same crops to grow for a long time in one region.

  • Analysis frame for undergraduate physics laboratory reports in collecting, processing, and analyzing data was developed. Using the frame and questionaries, we analyzed what difficulties students have in the concepts of error and uncertainty in writing laboratory reports. Students considered repetitive measurement for collecting data, but they didn't express it distinctly in their reports. They also had difficulties in measuring data around the extreme value or the large slope. Especially, most students have had difficulties with error and uncertainty. They can't apply the basic formulation to propagation of error and uncertainty. They also had the difficulties in analyzing data with concepts of error and uncertainty. While most students responded that error and uncertainty is important, there were few students who analyzed the influence of the cause of error on the results quantitatively. The result of the study showed that students have difficulties in writing the laboratory reports because they didn't have the correct concept of the error and uncertainty. So, it is needed to not only teach the physics concept about experiment but to teach basic concept of data collecting, processing, and analyzing specially about error and uncertainty for students as well.

  • The earth science curriculum and textbooks of the secondary school in South Korea and North Korea were analysed comparatively with the modified TIMSS curriculum frameworks. In the secondary school of North Korea, earth science is not provided with separate subject, but partly taught in geography. Geography is taught by two hour per week in the first to fifth grade of secondary school. Especially the first and the fifth grade geography are deeply related to earth science. The major aim of earth science education in South Korea is to develop creative problem solver having with interest and curiosity in searching natural phenomena and with basic science concepts and inquiry process skills. But on the other hand the aim of geography education of North Korea is to cultivate communist revolutionists who are faithful to IL-Sung Kim and Jung-IL Kim. In both Koreas the category of 'earth feature' and 'earth process' are dealt a lot, but 'earth in the universe' is rarely taught in North Korea, which suggests that separate subject of astronomy is instructed in the North. Generally the scope and sequence of earth science of North Korea comes under those of middle school of South Korea. Especially discrepancy in level of meteorology and astronomy area between North and South Korea is great.

  • In this study, we examined the adaptive practices of science teachers in their classrooms and their perspectives on the distinguishing features of these practices within science subjects. Our analysis comprised 339 cases from 128 middle and high school science teachers nationwide, and 199 cases on the characteristics of adaptive practices in science disciplines. The primary findings were as follows: First, the most significant characteristic of adaptive practice in science disciplines pertained to experimental procedures. Within the 'suggestion of additional materials/activities' category, the most frequently cited adaptive practice, teachers incorporated demonstrations to either facilitate student comprehension or enhance motivation. Additionally, 'experimental equipment manipulation or presentation of inquiry skills' emerged as the second most common adaptive practice related to experiments. Notably, over 50% of teacher responses regarding the characteristics of adaptive practices in science pertained to experiment guidance. Second, many adaptive practices involving difficulties experienced by students in learning situations were presented, particularly in areas such as numeracy and literacy. Many cases were related to the basic ability of mathematics used as a tool in science learning and understanding scientific terms in Chinese characters. Third, beyond 'experiment guidance', the characteristic adaptive practices of science subjects were related to 'connections between scientific theory and the real world', 'misconception guidance in science', 'cultivation of scientific thinking', and 'convergence approaches'. Fourth, the cases of adaptive practice presented by the science teachers differed by school level and major; therefore, it is necessary to consider school level or major in future research related to adaptive practice. Fifth, most of the adaptive action items with a small number of cases were adaptive actions executed from a macroscopic perspective, so it is necessary to pay attention to related professionalism. Finally, based on the results of this study, the implications for science education were discussed.
