Since based on the revised educational curriculum, the insects and spiders in eight biology textbooks I and II of high school are as follows. In class level, two classes, Insecta and Arachnida were investigated and their frequence numbers in the textbooks were a total of 143 times. In order level, 12 orders in insecta, 2 orders in Aranea were appeared in the textbooks. The most appearing frequence number was represented in Lepidoptera (33 times) and then in Araneae (11 times). For each publisher, the most appearing frequencies of insecta and spiders was shown in Gyohaksa (23 times), and then in Hyeongseol and Centurla education research institute (21times, respectively). In the textbooks, four species were found to misidentify in their species name and five mistakes were investigated in their photos and content.

In this study, high school science teachers' and students' various conceptions related to osmosis phenomena were compared with and analyzed in relation to the content of science textbooks used in high school science classrooms and college science courses. The questionnaires developed by the researchers were administered to science teachers and students. Differences can be found between the explanations of science textbooks on osmotic pressure and semi-permeable membranes. Many science teachers and students thought of osmotic pressure as 'membrane pressure occurred by the movement of a solvent'. Moreover, the types of teachers of semi-permeable membranes were similar regardless of their academic majors. Many of the teachers thought of a semi-permeable membrane as a membrane that 'passes small-size particles'; however, many students thought of this type of membrane as being 'selectively permeable'. Also, the salt-pickling cabbage phenomenon seemed to cause significant confusion to science teachers and students. These study results show that teachers and students possess various conceptions related to the osmosis phenomena. These different conceptions related to osmosis phenomena might cause confusion and diverse conceptions including misconceptions among teachers and students.

The proliferation of bioinformatics in modern biology marks a modern revolution in science that promises to influence science education at all levels. This study analyzed the contents of standards in the 7th and 2007 and 2009 revised high school biology curricula and compared the contents, amount and the presentation styles of bioinformatics with those of biotechnology in biology textbooks. In result, first of all, there are some vague expressions about biotechnology and bioinformatics in the 7th and 2007 revised curriculum. There is a clear expression about biotechnology in 'life science I' and 'advanced biology' of 2009 revised curriculum. Second, more biotechnology is introduced than bioinformatics in 'science', 'biology I', 'biology II', 'life science I' textbooks. Third, in 'biology for high class' textbook, amount of biotechnology contents in the 2007 revised curriculum didn't increase. An more effort to introduce bioinformatics to science high school student is needed according to revising curricula.

The purpose of this study was to compare the biology contents of elementary schools science textbooks between Korea and Japan. To this end, the organization of subject matter and the type, process and context of inquiry activities were analyzed. The findings of this study were as follows: First, the sheer number of topics presented at each grade level was considerable and the contents of science textbooks were fixed in a set form in Korea. However, the organization and development of contents were made by considering the state of things and seasons in the case of Japan. Second, the amount of inquiry activities in Korea was higher, but the relationship between concepts and inquiry activities was lower than in Japan. Third, actually conducting (or 'doing') inquiry type activities was highest in Korea, on the other hand, 'experimenting' appeared to have a higher priority in Japan. Fourth, inquiry processes of activities in each country were very similar, in that the ratio of performing an inquiry was high, and perceiving a problem or designing an inquiry was low. Fifth, the results of analyzing the inquiry contexts of activities showed that the framework of evaluating inquiry activities based on curriculum objectives should be provided in the earlier stages of science textbook development.

In this study, we analyzed types of explanation on osmosis concept that were represented in chemistry and biology textbooks of high school and college. There were 5 types of explanation on osmosis concept. The types of explanation were diffusion of solvent, collision, hydration, equilibrium of concentration and screen of holes. Last two types of explanation were classified into misconceptions. The various types of explanation on osmosis concept might cause to have be a reason that students had many misconceptions and to feel difficult to learn about osmosis concept. Many of textbooks is accord to types of concept explanation and figure explanation on osmosis but some is not.

One of the widely used applications of remote sensing studies is environmental change detection and biodiversity conservation. The study area Hustai Mountain is situated in the transition zone between the Siberian taiga forest and Central Mongolian arid steppe. Hustai National Park carries out one of several reintroduction programs of takhi (wild horse or Equus ferus przewalskii) from various zoos in the world and it represents one of a few textbook examples of successful reintroduction of an animal extinct in the wild. In this paper we describe the results of an analysis on the change of remaining forest area over the 7-year period since Hustai Mountain was designated as a protected area for reintroduction to wild horses. Today the forested area covers approximately 5% of the Hustai National Park, mostly the north-facing slopes above 1400 m altitude. Birch (Betula platyphylla) and aspen (Populus tremula) trees are predominant in the forest. We used Landsat ETM+ images from two different years and multi temporal MODIS NDVI data. Land types were determined by supervised classification methods (Maximum Likelihood algorithm) verified with ground-truthing data and the Land Change Modeler (LCM) which was developed by Clark Labs. Forested area was classified into three different land types, namely the forest land, mountain meadow and mountain steppe. The study results illustrate that the remaining birch forest has rapidly changed to fragmented forest land and to open areas. Underlying causes for such a rapid change during the 15-year period may be manifold. However, the responsible factors appear to be the drying off and outbreak of forest pest species (such as gypsy moth or Lymantria dispar) in the area.

Research into scientific inquiry methods indicates that providing various types of inquiry methods can enhance students' science loaming in terms of providing students with actual science in various ways' more so than exposure to one type of inquiry method. This article develops a framework for an analysis of scientific inquiry types based on the nature of scientific enterprise. We selected three types of scientific inquiry: these were minds-on activities, hands-on activities, and experimenting. Elementary science textbooks in the 7th national science curriculum were analysed according to the following subject areas; earth science, physics, biology, and chemistry. A total of 61 teaching units from 3rd through 6th grade science textbooks were investigated. The frequencies of each type of scientific inquiry method were slightly different among four science subject areas. The most frequent type which appeared in physics and chemistry was the hands-on type, while the minds-on activity type was the most frequent type which appeared in earth science and biology.

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.

This study is conducted to analyze the questioning styles of the parts of chemistry in 17 middle school science textbooks in terms of frequency, types, and placement of questions. The instrument was the Textbook Questioning Strategies Assessment Instrument (TQSAI) developed by the Cooperative Teacher Preparation Program, University of California in 1975. An averaged ratio of questionings/sentences (Q/S) of seventeen textbooks was 13.6% varying from 6.8% to 19.7%. Various question types were used in titles, early and middle steps in the sections except late steps. The comprehending questions were most frequent in the types of inquiry courses and the focusing questions were most frequent in the characteristics of instructional courses. The percentages of empirical questions for the total numbers of questions were slightly larger than nonempirical questions with values of 54.2% and 45.8%, respectively.

The consistency and balance of objectives by objective domains in units, sub-units and instructional units were investigated. The 6th elementary biology curricular teaching guidebooks were analysed. Domains of objectives are cognitive, inquiry process, instrumental skill, creative, affective and STS. Cognitive objectives were most dominant in all units, sub-units and instructional units. But no objective for creative domain were suggested. In unit and sub-unit, proportions of objectives were cognitive, inquiry process, affective, instrumental skill and STS domains in order. Objectives for cognitive and inquiry process domains were more than others in instructional units, Except cognitive and inquiry process domains, objectives for the others were not consistent in all units, sub-units and instructional units. Especially, the percentages of objectives for affective domain decreased in units, sub-units and instructional units orderly. These resulted from teaching objective domains categorized formally, Thus, it is necessary to develope curriculum and textbook to be consistent and balanced with objective domains and reflect upon the characteristics of them.
