  • We have investigated the magnetic education in elementary science of Korea. Text books and other related materials are analysed. Students learn playing with magnets in third grade and learn making electromagnets in sixth grade. Arrangement of topics are in accord with the historical development of electromagnetism in physics although the order is not well suited to other field of science. Teacher's guide books need to be developed to consider various environments in school such as city and country, and rich and poor town. Several details in the science textbook are pointed out for better education. Overall course looks sound.

  • Self-induction is an important concept in the field of electromagnetism, which is dealt with in all the high school physics textbooks. According to the results of the survey on self-induction, most of general high school students and even science high school students have overgeneralized concepts that high self-induced emf. are produced whenever the switch is turned off in the circuit containing inductors. The reasons of this overgeneralization on self-induction could be explained through the analysis of current high school physics II textbooks. Main reasons can be attributed to the fact that, by depending on their intuitive ideas, students try to vaguely explain the concept, based on lighting up of Ne tube in the special circuit. This study found out qualitative method to have students effectively understand self-induction based on quantitative interpretation to gain scientific understanding on self-induction.

  • In this study the concepts for science learning of physics and earth science presented in the seventh grade science textbooks for the seventh national curriculum of Korea approved by the ministry of education were analyzed in terms of the concrete and formal concept level. The parts of textbook analyzed for science learning consist of three sections in physics such as light, force, and waves, and three sections in earth science such as the structure of the earth, the substance of crust, and the movement and composition of the ocean. The analyzed results showed that the number of scientific concepts were differed from 54 to 74 in physics and from 86 to 120 in earth science depending upon publishers. In general, the concepts for science learning in the physics were found to be more in the formal level than the concrete level. However, the concepts for science learning in earth science were found to be more in the concrete level than the formal level. The analyzed results suggest that the concepts of science learning should be considered the learner's cognitive level and the sections should be disposed depending on the degree of difficulty for writing the science textbook. Therefore, it seems to be important to review carefully whether the textbook meets the object of the seventh curriculum of Korea during the process of the investigation for the science textbook.

  • The study is to analyze the middle school-science parts among the products of nation-wide science exhibition for eleven years recently and the results of compared to the content of science-textbooks of middle school. The number of observation in the student parts among the products of nation-wide science exhibition was the highest in all methods studied, whereas, most teachers surveyed experiments in their products. The mean Shannon's diversity index (DI) was same trend for students and teachers. There was a non-significant difference of the methods in students and teacher groups according to years and the association between students and teachers were closely connected with methods. The correlation between the content of students' products and texts of middle-school was highly positive for earth science, chemistry, and biology, whereas physics showed negative correlation.

  • High school common science is introduced by the sixth national curriculum. It consists of physics, chemistry, biology and earth science like the secondary school science. In this paper, textbooks are analyzed by the science teachers and the status of the present teaching and learning methods is reported. The detailed results are as follows; 1. Almost high school teachers choose textbook that included little the STS material. More than two teachers are teaching the high school common science and when they are chosen, they are independent with their major. 2. According to the national curriculum, they evaluated the textbooks as it is below the middle level. This evaluations are not dependent on teachers' comparement and textbook's class except the several matters based on STS (science-technology-society). 3. The teacher teaching the high school common science thought that teaching the textbook in school is worse than analysizing it. they must have emphasised on learning of inquire method than system of knowledge, introduction to material connected with real life and STS in the high school common science.

  • 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.

  • The opening period of Korea was the period of modernisation amidst the conflicts between conservative and progressive sections with penetration of Western powers after 1876. With the opening modernisation accompanied modernisation of education. Missionary schools established by protestant missionaries played a crucial role in educational modernisation in the period of opening. In this article, the process of educational modernisation and the ways in which the ideas of democracy and equality were taught in the earliest schools, Paejae, Ewha, Kyoungsin and Chungsin are analysed through the method of bibliographical investigation of the textbooks used by these schools. No textbook prior to 1900 was found and in general there were no textbooks such as we know today. Usually English reading material and the Bible were the main teaching materials. Teachers kept their own copies of hand-written texts which were translated versions of American textbook. Since the same teacher taught in a number of schools, they shared same curriculum. In the early period, English Bible was taught so that English and the Bible lessons were not separated but gradually history and geography were added. Teaching of Hangul, and Korean history were added to encourage the sense of national identity and patriotism. In the case of Chungsin, for biology class, pupils were sent to Che-jung-won to learn human physiology, chemistry and physics, which shows an emphasis on science education. Vocational education was carried out; in the case of Paejae, a printing workshop was set up enabling students to earn some money at the same time as learning. Also in Kyungsin, skills of woodwork and basket weaving were stressed. Ewha also held a bazaar of the work made in sewing classes. Establishment of missionary schools brought about a great contribution in modernising Korean society and the Christian spiritual education of these schools lay the foundation for building democracy in Korea.

  • Modem science education was introduced to Korea in the enlightenment period. The science textbooks which were published at that time were important to modem science education in Korea. Therefore, the translators and publishers of science textbooks were the leader of the science education in the enlightenment period. Hyun Chae and his son as a translator were one of the leaders in science education at that time. Hyun Chae was born to a Middle class (中人)family and succeeded to pass the national examination for translators (譯科). He worked as a translator and author at the Ministry of Education (學部). Also, he was the associate teacher in a foreign school and the Hansung normal school (漢城師範學校). He published 26 books. One of them, Rikwa (理科) as the science textbook covering all the areas of science, physics, chemistry, biology and earth science. That presented the knowledge, which students should know by proper method, induced students' interest and included various experiments. Hyun Chae's activity in science education as the author and translator of science textbooks was an important role on the forming science education in the enlightenment period because it was caught short of science textbooks. The author, translator, and publisher of science textbooks was of great significance to make science popular, which was the new culture. Therefore, the role and activities in science education of Hyun Chae was a part of the history of science education, he knew a foreign language and was the leader in facilitating exchange with foreign countries.

  • This research aims at investigating science teachers' perception of the refractive index of materials, and thus achieving proper information transmission and teaching of refractive index. Specifically, we have made questionnaires on what physical factors influence the refractive index of a liquid easily available in secondary schools. It was found that 80.0% of science teachers perceived that the density has the greatest influence on the refractive index, among a variety of factors such as molecular structure, the number of molecules per unit volume, mass of each molecule, and the wavelength of light, to mention just a few. This may be due to the fact that current textbooks deal with the refraction of light based on analogy to a mechanical wave. Such a misunderstanding may lead to confusion and misunderstanding for students.

  • The purpose of this study is to analyze how optics concepts and activities have changed according to the revision of the national science curriculum. For this purpose, the optics achievement standards presented in the middle-school science curriculum of the 7th curriculum, 2007 revised curriculum, 2009 revised curriculum, and 2015 revised curriculum, and the optics content presented in the textbooks developed for each curriculum, were compared and analyzed. The optics content is classified into four concepts: the process of viewing an object; light and color; reflection and refraction; and the image from a mirror and a lens. The main results are as follows: First, according to the revision of curriculum, some optics concepts have been added or removed. In particular, big changes have appeared in the concepts of "process of viewing the object", "dispersion", "reflection and refraction" and so on. Second, the content for 'image formation by a mirror and a lens' was gradually reduced, according to the revision of curriculum, and the level of activity was also adjusted. Third, attempts to present the content of textbooks in conjunction with the phenomena and tools that students can experience in everyday life have increased gradually. In addition, based on the analysis of the content of curriculum and textbooks, the implications for optics education have been discussed.
