In this study, we conducted a textbook analysis and a conceptual test in order to investigate misconceptions of preservice chemistry teachers in understanding motions of molecular gases. As a result, we found out that many of the general chemistry textbooks not only introduce motions of molecular gases by explaining basic conceptions and using simple models, but also omit the explanation on center of mass when dealing with rotational motion. The physical chemistry textbooks, however, mainly approach motions of molecular gases in terms of spectroscopy and use various models to explain more intensified concepts, referring the center of mass in rotational motions. Meanwhile, pre-service chemistry teachers' confidence and understanding in the motions of molecular gases were very low and pre-service teachers also had many misconceptions about them. We believe this is because they had a tendency to depend largely on their intuition based on the pre-conceptions and the visual materials in the textbooks.

The purpose of this study is to develop the programming language teaching materials for the gifted of information with using the game. There are many curricula for teaching the information and technology to the gifted of information. There are not differences between these programs and the general IT curricula. The gifted of information has some complains about his curriculum(58/60, 96.67%). So this study developed the alternative programming language teaching materials for the gifted of information. This study concluded the effects of alternative materials for teaching programming language depend on learners' academic achievement about programming language with game activity. This study also looks forward to being able to indicate new direction to develop the teaching materials for the gifted of information.

This study was to analyze science process skills related to 'state of matter' and 'state change of matter' in the kindergarten, elementary and middle school science textbooks. On the base of articulation, we analyzed science textbooks of the 5th kindergarten curriculum, the 6th elementary school science curriculum and the 6th middle school science curriculum. The findings indicated that the scientific inquiry abilities of predicting, classifying, hypothesizing and designing investigations are not enough in all grade science textbooks. Also, while young children have measuring ability theoretically, it was represented only in high grade textbooks. We concluded that these were inappropriate from the viewpoint of articulation which is related to scientific inquiry ability.

The purpose of this study is to improve education program for Informal Science Education Institution by analyzing education program of Natural History Museum, one of informal science education institution. This research subject is Seodaemun Museum of Natural History, located in Seodaemun-Gu, Seoul. It is Public Natural History Museum, which runs more than 60 education programs every year continuously for recent 6 years. Objects of this study are 32 education programs for 3rd to 6th grade of elementary school. The result of study shows that teaching materials of programs, run by informal science education institution, don't contain enough script and activity for improving creativity and inquiring mind. As the result of the study, it is required that guidance plan of education program be developed with more activities, teaching method and script, to seek quality of class than quantity of that when developing education program of science education institutes. And it is required to develop teaching material using creative technique and to improve medium and long term program for development of feedback.

In this study, the teaching material has been developed based on Polya's Problem Solving Techniques for preparing Korea Information Olympiad qualification and studying principle of computer. the basis of discrete mathematics and data structures were selected as the content of textbooks for students to learn computer programming principles. After the developed textbooks were applied to elementary school students of Science Gifted Education Center of J University, the result of study proves that textbook helps improve problem-solving ability using the testing tool restructured sample questions from previous test. We need guidebook and training course for teachers and realistic conditions for teaching the principles of computer.

현재 초등학교에서는 각 학년에 재량활동 시간을 활웅하여 매주 1시간씩 34시간이상을 정보통신기술교육 시간으로 배정하고 있다. 그러나 시대의 변화에 발맞추어 요구되고 있는 창의성과 문제해결력을 키워줄 수 있는 컴퓨터 교재가 개발되어 있지 않아 서 시대에 맞는 정보통신기술교육을 하고 있지 못하다. 그리하여 교육인적자원부가 발표한 정보통신기술교육 운영지침을 분석하여 창의성과 문제해결력을 증진시킬 수 있고 현장에서 쓰일 수 있는 5,6학년용 교재를 개발해 보았다.

The existence of appropriate teaching materials in foreign language is very essential especially if it is related to safety. Among them, the importance of textbooks is more emphasized because there is no suitable education or curriculum for EPTA (English proficiency test of aviation). A good textbook not only presents the right direction to study but also provides an efficient way to learn. This research exploded how well textbooks for EPTA are organized and analyzed current pilots' responses whether the textbooks are suitable for preparing EPTA through the questionnaire. The conclusion drawn is that textbooks for EPTA should be designed to encourage current and pre-pilots to learn how to communicate with controllers efficiently and briefly, and also should provide proper guide lines for preparing EPTA.

The purpose of this study was to find out the characteristics of learning contents structure of K-12 science textbooks. The characteristics are related to 7 main concepts of matter properties; reaction rate, other reaction, density, solution, state change, absorption, and surface property. The contects are analyzed into 5 types of characteristics; type of concept extension, type of concept deepness, type of same level concept, type of confusion with other concepts, and type of concept interruption. First two types are positive content structures, but the others are negative structures. The findings are as follows. First, a lot of learning contents have the characteristic of 'type of same level concept'. There are few which have the characteristic of 'type of concept deepness'. Second, there are a lot of concepts related to 'properties of matter' which are not represented any more in middle and high school science textbooks. Those concepts are importantly taught in early childhood education and elementary school science. Most of the learning contents don't represent 'type of concept deepness'. Therefore the science textbooks needs to be restructuring.

초등학교 시기가 올바른 식습관 형성에 중요한 시기임에도 불구하고 체계적인 영양교육을 실시하지 못하는 현실에서 2006년부터 시행되는 영양교사화에 큰 관심이 집중되고 있다. 그러나 현장에서 적극적인 영양교육을 행하기 위해서는 수업확보도 중요한 문제이지만 적절한 교재 및 매체의 개발이 필요하다. 초등학교에 제7차 교육과정이 도입되면서 가장 두드러진 특징 중 하나가 재량활동의 신설 및 확대일 것이다. 그러나 아직 학생들과 학부모의 호응을 얻을 수 있는 다양한 활동으로 구성, 운영되지 못하고 있고, 교재 또한 개발되어 있지 않아 일관된 교육을 제공하기 어려운 실정이다.(중략)
