  • The purpose of this study was to analyse students' achievement of 'Earth Science' in the Third International Mathematics and Science Study-Repeat(TIMSS-R), which was performed in 1999 with 38 nations participating. Korean 8th grade students' achievement of 'Earth Science' was compared with those of other countries and other content areas in science. Average percent correct of items in each subcategory was also analysed. Most of the 'Earth Science' topics were included in the intended curricula of Korea; they were taught to most of the students in science classes. Korean students ' average scale score of 'Earth Science' was significantly higher than the international average, but in comparison with other science content areas, achievement of 'Earth Science' was relatively low. The teachers' confidence in teaching earth science was lower than their confidence in teaching other science areas. The paper presents the results of item analysis and their implications for science education.

  • Numerical data of the geological time scale in Earth Science I, II textbooks and those of University textbooks of Korea and other countries are briefly reviewed. Numerical data of the geologic time scale shown in Earth Science I, II textbooks are mostly out of date and many of them follow those in the University textbooks of Korea. The same situation is apparent for introductory Earth Science or Geology textbooks of other countries as old data exist in their text books as well. There are many new data in the International Stratigraphic Chart (ISC 2000) and International Geologic Time Scale (IGTS 2003) recently updated by International Commission on Stratigraphy (ICS) and A Geologic Time Scale (GTS 2004). Among the new data, some important things are Paleogene and Neogene Periods of Cenozoic Era, Mississippian and Pensilvanian Epochs of Carborniferous Period, Paleoproterozoic, Mesoproterozoic, and Neoproterozoic Eras of Proterozoic Eon, and Eoarchean, Paleoarchean, Mesoarchean, and Neoarchean Eras of Archean Eon. These new data should be used in the new Earth Science textbooks.

  • Examining research papers and other texts on the subject, this study summarizes previous studies, with focus on circulation as a subtopic of Earth Systems Education. In relation to the Earth Systems unit included in the revised 10th-grade science textbook, this study explains the meaning of Earth Systems and the basic concepts of Earth System Science. It surveys the origin and application of Earth Systems Education, which developed primarily in the U. S., and introduces its objectives, concepts, and communicated content. It also reviews the contents of Earth Systems Education adopted in the Korean school curriculum, and provides a comparative analysis of the content on circulation appearing in Earth Science I textbooks. Finally, it is proposed that an understanding among educators of Earth Systems and of its necessity as a subject of education is imperative for Earth Systems Education to become firmly established as a compulsory component of the national school curriculum.

  • The purpose of this study was to explore the elementary students' perceptions of Earth systems and environmental issues. A survey was conducted to determine the students' perceptions on the following aveas: (1) the concepts of certainty and tangibility, (2) self-reported knowledge level, (3) perceived danger level of selected eight Earth systems and environmental issues, and (4) their primary information source on these issues. Results indicated that ozone hole, acid rain, El $Ni\widetilde{n}o$, and global warming were identified by the students as uncertain and intangible issues. Perceived certainty and perceived tangibility were highly positively correlated with self-reported knowledge compared to other relationships. The results also showed that learning from school was the most frequent information source for environmental issues. The second most frequently used source of information was television among several mass media sources. It is hoped that this study contributes to understanding the elementary school students' perceptions toward the selected Earth systems and environmental issues.

  • Global Science Literacy is proposed as an international curriculum standard for science literacy. It is based on the science curriculum construct of Earth Systems Education, which has come out of the earth science education community in the United States. The presentation will briefly describe the nature of ESE, and include, if sufficient time, an audience participation simulation of mass extinction.

  • In this study, searched how science museum reflects personality of course of study and target comparing display contents of science museum with high school earth science Ⅰand Ⅱ of the 7th curriculum. Result of this study is as following. First, area that earth science contents of course of study are exhibited has been less than 50%, and is preponderated by unit. Second, earth science course of study reflection degree of science museum is middle.(2.8 points of perfect score 5 points) Third, number of average mark of contents that is exhibited by science museum in significance level 0.05 lows is difference, and it is no difference by unit.
