In this study, we propose the composition of contents on the area of astronomy for high school Earth Science elective courses for the 2022 revised curriculum based on high school students' perceptions of changes in Earth Science core concepts over the curriculum revisions, and analysis of learning elements in the area of astronomy for domestic and foreign Earth Science curriculum. Four Earth Science education experts compared and analyzed the astronomy contents presented in Korea, the US, British Columbia (BC) in Canada, Japan, and the International Baccalaureate Diploma Program (IBDP) curriculum. According to the survey results, high school students who answered that they were most interested in the core concepts of astronomy expressed a lot of regret that the contents related to astronomical observation were eliminated from the 2015 revised curriculum. As a result of comparing domestic and foreign curriculum, Korea and IBDP curriculum dealt with the largest amount of learning elements in astronomy. In the case of BC in Canada and IBDP, astronomy was offered as an independent subject, and the curriculums of Japan and Korea dealt with astronomy in the Earth Science subject. According to the results, it is necessary to develop general elective courses in Earth Science with astronomy-related contents with high discriminating power in order to strengthen astronomy education. Since astronomy requires background knowledge from various disciplines and inter-disciplinary learning was required, it is necessary to organize the career-related elective courses in Earth Science so that astronomy can be dealt with according to the knowledge structure of general Astronomy. Based on the research results, ways to organize astronomy contents for Earth Science elective courses were suggested.

This research was about analyzing students' major error types in the field of elementary 1st grade mathematics numbers and operations, and formulating and applying effective teaching methods to find out their effects. Among the errors the students were making, it was found that in the field of numbers there was more than 50% chance of making calculation mistakes in 50 rounds of rational counting. Also, in the field of operations, it was discovered that most of students' mistakes had to do with subtraction. The results from the classification of the 4 types of error showed that most errors were made from having inaccurate concept of knowledge and definition. Thus, it can be concluded that when elementary 1st grade teachers teach students mathematics, it is most important that they put best effort into firmly establishing the students fundamental concept, definition, facts, and functions. For that matter, students were interviewed one by one, and by implementing learning method using some concrete materials as tools, students were able to fix their own errors. More importantly, students were able to gain interest and become more willing to participate by joining in this program, which led to more effective guidance.

The purpose of this study is to investigate the effect of students' formation of evolutionary concept and learning on the development of digital teaching materials. The explanation of biological evolution, which explains the changes that living organisms undergo over a long period of time, can provide various contents for use in a book. The production and editing of images in digital textbooks would provide explanation of difficult concepts in a fun way. For this study, we designed instructional materials consisting of four class hours using iBooks Author, an electronic book authoring tool based on the 5E learning cycle model. In order to verify the effectiveness of the developed digital textbooks, we compared instructions by the general textbooks to those using digital textbooks. Both teaching through general textbook form and teaching using digital textbook materials had a significant effect on the formation of the concept of evolution, but interest in biological science and evolution increased significantly only in the group taught using digital textbooks. As a result of testing the instruction effect by the digital textbooks by classifying the students by type, the group that is familiar with smart devices was more active and interesting in class depending on digital literacy. The satisfaction of the developed digital textbooks also showed a positive score in the group with high digital literacy. The results of this study suggest that the development of digital textbooks in the unit of evolution can be an instructional material for easy and interesting approach to difficult concepts in the teaching of evolution.

This study is an action research aimed at improving the instruction of a teacher educator who teaches science teaching methods to elementary preservice teachers. After identifying the cause of their low levels of curiosity and interest in physics, teaching plans addressing this problem were explored, applied to classes, and reflected upon. Through this process, ways to improve teaching practice in science classes for elementary preservice teachers and pique their scientific curiosity and interest were proposed. A spiral implementation structure that repeats implementation and reflection a total of three times was designed for the prospective preservice teachers who participated in elementary science textbook research physics classes. Self-reports, student participation data, and results from both peer and self-evaluations were collected and analyzed. The reasons for the preservice teachers' low levels of curiosity and interest in science were identified as their inability to recognize and express information gaps and their low levels of willingness to resolve this. Practice expressing information gaps, raising the level of knowledge to be able to recognize information gaps, and a strategy to have the will to resolve information gaps were introduced into the class. To the extent that changes can be made by improving unit classes, elementary preservice teachers can express their curiosity and interest in science through this process.
