The purpose of this study is to investigate the effects of research project activities using the science writing heuristic on science inquiry abilities and attitudes toward science in high school students. For this purpose, we conducted the research project activities using the science writing heuristic consisting of questioning, experimental design, observation, argument and evidence, reading, and reflection steps for 73 students of the second year of science core course in high school in Jeonnam. In order to analyze the effects of the program, we surveyed the scientific inquiry ability and attitude toward science, investigated the perception of the research project class applying science writing heuristic, and conducted interviews when there was difficulty in interpreting the results. And the results of this study are as follows. First, among the science inquiry abilities, the score of Reasoning, Hypothesis setting, Finding variables, Operational definition, Experimental design, Graphing and data interpretation, Generalization was significantly improved statistically (p<.05), but the score of Expectation was not statistically significant (p>.05). Second, among the attitudes toward science, the score of 'Leisure interest in science', 'Enjoyment of science lessons', 'Career interest in science' was significantly improved statistically (p<.05). And the score of 'Attitude to scientific inquiry' decreased but it's not significant statistically. The high school research project applying science writing heuristic had a positive effect on scientific inquiry ability and scientific attitude but it could be burden to students because it is led by students in a form different from general science class for a long time. And so continuous study on research project that minimize these disadvantages and maximize their merits is needed.

This study was conducted to analyze the relationships between terms, learning concepts and inquiries in ocean unit, the National Common Basic Curriculum. The several science textbooks were selected to use for study, written in accordance with the 7 current national curriculum for the fourth grade of elementary school, the seventh of middle school and the tenth of high school. The higher the school level becomes, the frequencies of using terms related with ocean region get. The explanation of terms, however, has a tendency to be less frequent in the high school level. In the perspective of learning concept, there are more concrete concepts than formal concepts regardless of school level. Pure scientific context appears most often in inquiry contest through the whole course of every school level. In respect to inquiry process, the frequency of integrative inquiry process is on the increase as the school level gets higher. From the viewpoint of inquiry activity, there have been a lot of discussions, experiments and investigations in every school level, while high school does not the present any field study and project. Through these result, it is considered that the explanation of main terms is inevitable in the textbooks as basic educational material without regard to school level. In learning concept and inquiry context, a well-rounded learning is needed in relation to students' cognitive development and science-technology-society. Especially for the inquiry activity of earth science education, the educational effect is remarkable through field study; its appropriate application is required, accordingly.

Mathematics education is very important in future because mathematics is the basis of every study, for example, natural and social science, etc. Our nation wide curriculum has been revised six times since 1948. In 1992, the sixth revision was enforced and we are using the revised textbook now. This study aims at helping of continuous investigation for educational curriculum and textbook, and aims at efficient teaching by preventing unnecessary repetition and excessive gap in real field by analyzing the articulation of Analytics part in school textbook from elementary to high school. This thesis consists of the followings. 1.Investigation of the principles and natures of articulation along with curriculum course and notice the articulation based on the analysing tools. 2.Importance of learning functions. 3.To get the propriety, formation of 8 judging group and classification of content materials in function chapters by the judges based on the analyzing tools. 4.Analysis of presentation method and terminologies in the first concepts, suggestion teaching method to reduce gap and help of understanding on first concepts in the study of function. As a result 'development' consists of 55.8% of the total and it is higher than 'duplication' and 'gap'. To be specific in periods, between elementary school and middle school 'development' takes 64.5% and this shows an acceptable articulation in the period. While 39.4% of 'gap' in articulation between middle school and high school looks high compared with 'gap' between the previous periods. The item suggested with the 'gap' is the 'definition of function', 'value of function', 'parallel translation', 'exponential and logarithmic function'. It is observed that these materials is suddenly appeared in high school.

Among the changes of the Curriculum from the liberation to the present, the biggest change in the highschool geography course appeared during the period from the Period of Syllabus to the 1st National Curriculum. More specifically, during the 1st National Curriculum the highschool geography course which previously had three subjects, 'Natural Environment and Human Lives', 'Human Geography', 'Economic Geography' was reduced to one subject, 'Human Geography.' In addition, while some contents related with astronomy, geology, and biology had been contained in the physiography course, they were left out from the human geography course of the 1st National Curriculum. This reduction of the geography course was related to the context that earth science was newly established in the 1st National Curriculum. Originally the draft plan released in June, 1953, which was 10 months before the formal time allotment criteria list had been made public, contained 'Physical Geography' instead of 'Earth Science'. What is sorry is that the name of 'Physical Geography' did not remain and was changed to 'Earth Science'. The underlying causes of the crisis the geography education is now facing are the reduction of Physical Geography and the emergence of 'Earth Science' during the 1st National Curriculum. To overcome the present crisis, the subject of geography should be changed more meaningful one based on the comprehensive perspective and academic product that geography has accumulated.

The goal of this study is to explore ways to restructure Convergence Elective Courses in science in preparation for the high school credit system, ahead of the 2022 revised science curriculum. This study started from the problem that the 2015 revised science curriculum has not guaranteed science subject choice for students with non-science/engineering career aptitudes. To this end, a survey was conducted by randomly sampling high schools across the country. A total of 1,738 students responded to the questionnaire of 3 science elective courses such as Science History, Life & Science, Convergence Science. In addition, in-depth interviews with 12 science teachers were conducted to examine the field operation of these three courses, which will be classified and revised as Convergence Elective subjects in the 2022 revised curriculum. According to the results of the study, high school students perceive these three courses as science literacy courses, and find these difficult to learn due to lack of personal interest, and difficulties in content itself. The reason students choose these three courses is mainly because they have aptitude for science, or these courses have connection with their desired career path. Teachers explained that students mainly choose Life & Science, and both teachers and students avoid Science History because the course content is difficult. Based on the research results, we suggested ways to restructure Convergence Electives for the 2022 revised curriculum including developing convergence electives composed of interdisciplinary convergence core concepts with high content accessibility, developing convergence electives with core concepts related to AI or advanced science, developing module-based courses, and supporting professional development of teachers who will teach interdisciplinary convergence electives.

The purpose of this research was to find the solution of problems originated from financial illiteracy. To accomplish this task, the content which supposed to be taught in the area of personal finance in the Elementary, Middle and High School curricular were identified based on the previous research. Then, the personal finance content taught in public education system were analyzed rising content analysis of over 100 text books related to Personal finance education, such as Home Economics, Social Science, Economics, and Human Life Sciences, etc. Based on the results, followings were concluded. In spite of the fact that only few personal financial education topics were included in the 7th Education Curriculum, many topics taught in the subject of Social Science were duplicated in the Home Economics Curricular. To accomplish the ultimate goal of personal financial education, an introduction of the new course(Personal Finance) in the regular curriculum like U.S. is strongly recommended.

The response of respiration rates of root, Ao layer and mineral soil to varying environmental factors was studied in Popuius maximowiczii stand (25-year-old) during the growing season of 1997. Soil temperature showed a pronounced seasonal course, in contrast to soil moisture. The mineral soil respiration was high in August, and root and Ao layer respiration, were high in July. An exponential equation best described the relationships between soil temperature and mineral soil respiration, and total soil respiration (r＝0.95 and 0.92, p＜0.001), respectively. In P. maximowiczii stand, soil respiration rates were reduced by about 19% after removal of the Ao layer, and by about 30% after removal of living root. Therefore, mineral soil respiration seemed to contribute gretly to the total soil respiration (50%).

The purpose of this study was to examine the content relevance of the 7th national primary science curriculum and textbooks. To fulfill the purpose of the study, we 1) analyzed the 7th national science curriculum of Korea, Californian science standards, the national science curriculum of England and Japan, and current Korean and Japanese science textbooks, 2) conducted a nationwide survey to gather opinions from students, teachers, and professors of teachers colleges about the relevance of the science curriculum and textbooks. Main findings of this study are as follows: First, the science contents at each grade level should be determined by the students' characteristics, not by an equal portion rule among physics, chemistry, biology and earth science. Second, the excessive overlapping and repetition of contents due to the spiral curriculum should be avoid. Third, the number of topics at each grade level should be reduced, and the similar topics and themes should be integrated for students' deeper understanding. Fourth, the number of science concepts and activities should be reduced to an appropriate level considering the time allotment for science classes, teachers workload, laboratory conditions, etc. Fifth, differentiated curriculum, such as in-depth and supplementary course, should be described not in science contents, but in teaching and learning strategy.
