  • This study compared and analyzed the contents of secondary earth science curriculum in Mongolia and South Korea to check the contents of earth science education in both countries and to prepare basic data necessary for future earth science curriculum revisions. The research questions of this study are: first, to understand the changes and current operating conditions of earth science curriculum in both countries, to compare and analyze with other foreign cases, and second, to compare and analyze the contents of earth science and curriculum in both countries. The TIMSS evaluation framework is used to compare and analyze the earth science-related contents included in the science curriculum of middle schools. For analyzing the contents of high school, the contents of NGSS in the United States and the earth science curriculum contents of high schools in South Korea were mixed and the analysis frameworks were created and validated by experts. As a result of the study, countries that follow the Russian-style education system did not organize and operate earth science as an independent science subject, and deal with earth science-related content in the natural geography area of the geography subject. The earth science contents covered in middle school science curriculum in both countries, 18 of the 27 content elements of the TIMSS content analysis framework were matched in Mongolia and 20 in South Korea. In high school curriculum, the contents of earth science in Mongolia were described more briefly and not covered than in South Korea. In particular, the Mongolian geography curriculum dealt with many environmental issues. The emphasis on the operation method of the earth science curriculum in Mongolia and the contents related to the environment can be used as a reference when developing an interdisciplinary integrated curriculum of science and social studies in South Korea.

  • In this research we conducted a survey on the actual status of the 7th National Earth Science I & II curriculum to explore ways of revising the next Earth Science curriculum for better education. Of the 180 Earth Science teachers, 60% responded to the survey. The domains of the survey consist of (1) the necessity of Earth Science I & II curriculum revision, (2) educational goals, (3) content coverage, (4) level of difficulty and students' interest for Earth Science content, and (5) ways to overcome the crisis of Earth Science education. Majority of the respondents demanded the revision of Earth Science I, II curriculum because of overlapping and repetition of contents among 10th grade science and Earth Science I and overcrowded Earth Science II contents. Based on the survey results, recommendations on how to improve Earth Science I, II curriculum and how to adjust Earth Science contents are suggested. In addition to curriculum improvement, systematic supports are required for Earth science not to be excluded and turned down by the student and the scholastic aptitude test for university admission.

  • The purpose of this study is to provide meaningful basic materials for organizing a science curriculum in future by analyzing the status and changes of contents about astronomical phenomena in textbooks according to the changes of the science curriculum of elementary school. A main target of analysis is science textbooks of elementary school in curriculums from 1st to 7th. For the analysis, the analytic frame based on contents in astronomy textbooks of teachers colleges and colleges of education was used. The result of the analysis is as in the following. First, astronomy accounted for average about 7% of all pages of textbooks in all of science curriculums. The 1st educational curriculum had the most learning quantity of 10.40%, and the 6th curriculum had the least quantity of 4.39%. These results show that astronomy was not a small part and was considered important in each science curriculum of elementary school considering that earth science accounted for 17-26% of all pages in elementary school science curriculum. Second, the things that have been dealt with in common in all science curriculums from 1st to 7th of elementary school are the shape of the earth, the rotation and the revolution of the earth, the occurrence of the seasons, the apparent motion of the sun, the status and motion of the moon, the movement of a star, the brightness and distance of a star, constellations, the sun, planets and others. These contents are expected to be dealt with continuously as basic contents to organize astronomy regardless of the changes of curriculum. Third, in science curriculum of elementary school, astronomical phenomena based on life experiences regarding the earth, the moon and the sun are mainly dealt with in the first and the second grade. Contents requiring principles-understanding and research are dealt with in the fifth and sixth grade. These results show that elementary school science curriculum dealing with astronomy reflects the developmental stages of students and considers principle of learning possibility.

  • The purpose of this study is to examine the Earth science content relevance of the 7th national science curriculum. For this purpose, we (1) analyzed science curriculum or content standards of Korea, California, England and Japan, (2) compared science textbooks of Korea and Japan, (3) conducted a nationwide survey to gather opinions from students, teachers, professors and textbook authors about the relevance of the science curriculum and textbooks. According to the results, the Earth science contents of the 7th national science curriculum were not appropriate in terms of the objectives of science curriculum and the needs of students and society. The main reasons include the equal division among physics, chemistry, biology and earth science, iack of connection due to fractionation of units, overly strict application of spiral curriculum, and redundant amount of activities and concepts to cover in the textbook. Major suggestions fir securing the relevance of Earth science contents are as follows: First, the science contents and the size of units at each grade level should be determined according to the students' characteristics, not by equal portion rule. Second, the excessive overlapping and repetition of contents due to the spiral curriculum should be avoided. In addition, the number of activities should be reduced and the quality of required science activities should be improved. Third, to raise students' interest in Earth science, real-life applications and real-world Earth science contents should be emphasized including natural disasters, safety, universe and space exploration, and natural resources. Lastly, considering one of the relevance criteria is feasibility, supports for schools and science teachers are needed to realize the goal of the intended science curriculum.

  • This study analysed student teachers' notable questions about the earth science contents in the elementary science textbooks. The contents of notable questions were defined as ‘notable question contents 1' and 'notable question contents 2'. Both the question contorts are contents about which the number of questions is above three times and from two times to three times as much as the mean number of questions per page of each unit respectively. The results are as follows. First, question contents 1 are found as 'clouds observation', 'geological strata formation' and so on. Question contents 2, 'rainfall measurement', 'moon's movement during one night' and so on are found. Second, the number of interrelationships of main terms in questions increased in each question of question contents 1, but 4 term-patterns are found more in question contents 2 than question contents 1. Third, high interrelationship patterns of terms in question contents 1 are 'coal and petroleum-generation', 'metamorphosis-heat and pressure', 'metamorphosis-heat and pressure-metamorphic rocks', 'planet-sun-comet-revolution' and in question contents 2. 'constellation plate-use', 'dryness and wetness hygrometer-principle', 'seismograph-principle-earthquake', 'earth rotation axis-tilting-occurrence', 'dryness and wetness hygrometer-principle-humidity' and so on. The sources of questions analysed in this study are estimated as the content construction system of textbooks, or students' general questions about the earth science contents. If this is the former, the problems in texts and illustrations in textbooks should be articulated and resolved. And if the latter, the elementary science curriculum has to be reconsidered in view of scientific literacy in earth science.

  • The purposes of this study can divided into three parts: First, to investigate high school science teachers' understanding concerning geologic time; second, to analyze contents related to geologic time in the secondary school science textbooks and teachers' guidebooks; and third, to compare the response type of science teachers using the results of the contents. Forty high school science teachers in the Chungbuk province are chosen to answer to the questionnaire. Many teachers (50%) think that the age of Earth is simply measured by radioisotope. However, most of them do not know the measuring method in detail. The over 50% of the teachers think that the uniformitarianism, law of superposition, law of faunal succession law of unconformity, and law of intrusion are the great five laws of historical geology. Many part of the contents related to geologic time in the textbooks and guidebooks are incorrect and described distinctly from each other. Such content includes the age of Earth, age of the oldest rock in Earth, definition and range of geologic time, measuring method of the Earth's age, and law of historical geology. Many of the science teachers do not have a complete understanding of the contents related to geologic time. This study suggests that the reason lies heavily on the contents described in the textbooks and guidebooks. Therefore, it is necessary to review and revise the contents related to geologic time in the textbooks and guidebooks.

  • The purpose of this study is to analyze illustrations, contents, and experiment in 6 kinds of science textbook from the 9th grade covering the phase change of the Moon (on the phase change of the Moon in six 9th grade science textbook) and to suggest coherent and effective contents and frame of the science textbook. Hence, the researcher decided the study problem. The study problems are as follows; 'Are the illustrations in the science textbook presented to help understand the phase change of the Moon depending on the position of the observer?', 'Does the contents of the book clearly mention the phase change of the Moon?', 'Can students understand the phase change of the Moon through the experiments in the science textbook?', 'Do illustrations, contents, and experiment of the science textbook consistently explain phase change of the Moon?'. 10 persons (9graduate students including the researcher) took part in this study. All things unanimously agreed upon by all participants were reflected in the results. The results are as follows. First, the universe observer's view point is mixed with the earth observer's view in illustration of these science textbook regarding the phase change of the Moon. Moreover, illustrations of some textbooks are presented with such words as 'sunrise', 'midnight' and consequently contain too much contents. Second, the contents of the science textbook concerning the phase change of the Moon is not described clearly. In addition, they don't give clear and detailed explanations for the reason of the phase change of the Moon. Third, all of the textbooks, except one textbook, describe the experiment regarding the phase change of the Moon with the earth observer's view point but don't specifically mention that the view point is that of the earth observer's view point. Fourth, illustrations, contents, and experiments in the science textbook don't coherently explain the phase change of the Moon. In addition, it is confirmed through the process of the result analysis that the described contents in the science curriculum is not well constructed or logical.
