  • 컴퓨터의 사용이 보편화됨에 따라 컴퓨터와 사용자 사이의 쉽고 자연스러운 의사 소통을 위한 자연어 인터페이스에 대한 연구가 활발히 진행되고 있다. 이 중에서 특히, 음성인식 분야는 음성명령, 받아쓰기 시스템 등 일반적인 컴퓨터 사용자의 요구를 충족시켜 줄 수 있는 분야로 주목을 받고 있다. 그러나 음성인식은 인식 자체만으로는 인식률에 한계가 있으며, 인식 결과를 향상시키기 위해서는 후처리 단계가 필요하다. 본 논문에서는 음성 인식의 성능을 향상시키기 위해 음성 인식의 결과로 들어온 연속된 한국어 음성을 올바른 음절로 복원시켜 주는 시스템을 구현하였다. 이 시스템에서는 어절단위의 연속된 한국어 음성을 입력으로 받아 한국어 발음 규칙을 역으로 적용하여 원래의 음절로 복원시키고, 형태소 분석기를 이용하여 복원된 음절이 올바른지를 확인하고 수정한다. 초등학교 교과서에 나오는 문장을 대상으로 본 시스템의 성능을 실험한 결과, 90.42%의 복원율을 나타내었다. 현재 정확하게 복원이 되지 않는 것 중에는 동음이의어가 차지하는 비중이 크며, 이 문제는 구문분석이나 의미분석을 이용하여 어느 정도 개선할 수 있을 것으로 보인다.

  • The national reform document, Science for All Americans (AAAS, 1990), and the Next Generation Science Standards (NRC, 2012) emphasize the importance of the nature of science in guiding science educators in accurately portraying science to students. Therefore, it is important that textbook materials convey an accurate conception of the nature of science. This study employs content analysis to examine the content of textbooks in US and Korea elementary science textbooks with regard to the four aspects of the nature of science: (a) nature of scientific knowledge; (b) nature of scientific inquiry; (c) nature of scientific thinking; and (d) nature of interactions among science, technology, and society (Chiappetta, Fillman, & Sethna, 2004). Intercoder reliability was determined by calculating Cohen's kappa (Cohen, 1960). Findings show that while US elementary science textbooks are not balanced in presenting the four aspects of the nature of science regardless of the publishing companies, the presentation of the nature of science in Korean elementary science textbooks have better balanced treatment of the four themes across the grade levels. On the other hand, both US and Korean elementary science textbooks are attempting to convey an idea of what science is by emphasizing scientific knowledge and investigation.

  • The purpose of this research is to examine the current state of inserting illustrations in science textbooks under the 7th Revised Educational Curriculum which is currently enforced in all grades of elementary schools, and to compare and analyze the external and internal differences in illustrations in science textbooks of elementary schools in Tanzania and Korea to present desirable direction of producing illustrations. There are not only some differences in rate of the kinds and role of the illustrations in grades, but also in both countries. In Korea textbooks, Photographs were mainly used to guide the students into experiments and to train the students in analyzing and interpreting data. In contrast, the Tanzania textbooks place more emphasis on pictures to enhance their interests and curiosity and understand. The Korea textbooks have to place more various illustrations instead of photos but the Tanzania textbooks should place more photos. As a result the addition of more diverse forms of illustrations and the re-organization of illustrations according to the topic should be considersd in future Korea and Tanzania textbooks.

  • The emphasis in environmental education for children should be on awareness, appreciation, and sensory experiences. By offering children opportunities to experience the elements of nature that surround them, teachers elevate children's comfort level and familiarity with the natural world. But many children have little contact with nature, because of urban living, hurried schedules, TV's attraction, and the low value most schools place on outdoor activities. So, teachers have to expand the real out-of-door experiences into the classroom by sharing and making accessible books focusing on nature and the natural environment. Namely, quality children's literature is an excellent vehicle for extending a particular experience or introducing new ones. Building on outdoor experiences through stories encourages children to explore more deeply what they have observed and experienced-concepts are reinforced, new knowledge gained, vicarious experiences provided. There are three-fold classification of environmentalism, especially environmental ethics, and three-aspects of the history in children's literature. The analytical results of this study are as follow. The environmental ideology in elementary Korean textbooks varies from 'egocentrism-didacticism' to 'ecocentrism-fantasy'. This finding has implication for selecting children's books and teaching environmental contents in elementary school. Therefore teachers and parents need to get ready to receive ecocriticism.

  • The purpose of this paper was to compare and analyze the elementary curriculum and textbook integration of social studies in Korea, USA, and England in terms of content integration and to make suggestions for the improvement of Korean social studies curriculum and textbooks. For this study, social studies curriculum and textbooks of three different countries were analyzed according to the three criteria: sequence, types and focus of integration. In this comparative study, five suggestions were made for the improvement of the Korean elementary social studies curriculum and textbooks. First, Korean social studies curriculum should have a subject focus at each grade level. Second, it is recommended that Korean social studies curriculum should present clear interrelations among geography, history, and civics at each grade level. Third, Korean social studies curriculum needs to have diverse criteria on which to select and organize themes. Fourth, Korean social studies textbooks need to have increased number of interdisciplinary large units. Fifth, it is necessary that the authors of Korean social studies textbooks integrate contents in consideration of students' life context in order to raise the relevance of the contents of history and geography.

  • The purpose of this study was to analysis natural disasters which can be applied environmental education for elementary students. For this study, the elementary society and science textbooks were selected. The results of this study are as follows. the society textbooks contain 2 units of the natural disaster in the 4th and 5th grades. In the science textbooks, 5 units of the natural disaster were showed in 3rd, 5th and 6th grades. The learning quantities were 4 hours in society textbooks and 7 hours in science textbooks. In society textbooks, the contents relating meteorological disasters were dominance. But the science textbooks were showed both meteorological and geological disasters. In aims of learning, while the society textbooks were focused as damages, prevention, counter-plan and restoring plan of the natural disaster, the science textbooks were emphasized damages. the photos in society textbooks, meteorological disasters were superiority in number; especially the flood and heavy rain were 76%. In science textbooks, the photos about earthquake were prominent as 40%. For activating environmental education in elementary school based on these results, it can be suggested that the effects of natural damage as tsunami and global warming should add to elementary textbooks. And the elementary teachers need to understand contents and photos relating environment problem in the elementary textbooks.
