The purpose of this study was to investigate how congruently the learning objectives of Earth Science I textbooks match the 2009 revised Earth Science curriculum. For this purpose, we classified the learning objectives of curriculum and textbooks were into three factors including ability, cross-cutting concepts, and behavioral verbs. The text data were analyzed using the semantic network analysis method. The results are as follows. The learning objectives of textbooks with regard to ability factors mainly emphasized the cognitive and affective domain. In addition, the ability of inquiry performance was emphasized in the learning objective of the curriculum. The textbooks used various sub-frame of cross-cutting concepts in comparison with the curriculum. Both textbooks and curriculum used the term 'comprehension' the most as behavioral verbs. However, most behavioral verbs just remained at the level of cognitive system.

In this study, teaching-learning activities were developed based on computational thinking (CT) in high school Earth Science I Solid Earth domain. And their effects and implications were examined. To this end, 8 sessions unplugged activities based on problem solving were developed, and applied it to 65 high school students. As a results, significant changes have been were confirmed in both student's perception about CT and CT. After that, based on student's responses to self-reports and interview, the affecting factors for perception about CT and CT in the earth science problem solving process were investigated. In addition, implication that should be considered in terms of design and progress of teaching-learning based on CT were derived. Based on these results, the necessity and operation of teaching-learning activities was suggested for developing CT through various subjects including earth science.

The purpose of this study was to analyze the questions of earth science knowledge presented in elementary science textbooks. In group activities, The questions were created by preservice elementary teachers assuming that they were teaching the earth science knowledge in science education classes at university of education. Types, frequencies, and sources of the cognitive background knowledge of the questions were analyzed. The results demonstrated the followings. First, types, concentrations, and sources of the cognitive background knowledge of the questions were different depending on the domains of earth science. Specifically, in astronomy domain, the frequencies and concentrations of the questions showed different trends compared with other domains in its individual lessons. It suggests that instructional strategies that reflected the difference found in each lessons be appropriately designed and used. Second, it was found that 'schools' was the most dominant sources of the cognitive background. 'Friends' were also found to be very important sources, thus promoting students' interaction with their peers would become an important strategy in science teaching. It was also found that mass media such as 'internet' and 'TV' were roughly rated the same as 'schools' which illustrated that mass media could be utilized in science instruction. Third, since types, concentrations, and frequencies of the questions were diverse in the lessons of units, it is suggested that diverse instruction strategies also be taken into account as an educational approach in teaching the subjects in teacher education.

Natural history museums used to be called an "informal learning institute". It is based on the assumption that their exhibition and exhibits are supposed to reflect school science curriculum and support school science programs. This study is to explore how this assumption is verified in terms of content-wise connections between school science and museum exhibits. In this study, 461 Earth Science related exhibits were selected from the Smithonian Museums and the American Museum of Natural History in the U.S. and analyzed with several instruments. The instrument targeting on Earth Science curriculum was framed based on the Third International Mathematics and Science Study (1993) and the National Science Curriculum Standards (1996). Other than content-wise connections, this study investigated exhibition characteristics related to better learning of science: these characteristics were types of activities, exhibition media, exhibition technology, and presentation methods. The nature of science shown in exhibits were examined as well. Natural history museums were reconsidered for their relevance and potential as informal educational venues from this study.

This study is to search the problems of schoolyard teaching material developed by pre-service earth science teachers and the critical factors affecting material making. The 258 schoolyard teaching materials was collected from 54 pre-service earth science teachers (male: 18, female: 36) major in Earth Science Education in Jeonju, Korea. The schoolyard teaching materials was greatly influenced by making process type of it and the prior knowledge of pre-service earth science teachers. As schoolyard preference exploratory type rely on their prior knowledge to develop the schoolyard teaching materials, they made use of the limited concepts like fault in material making. But the concept preference exploratory type made use of concepts not accessible to majority of pre-service earth science teachers because they selected a concept from the earth science textbook first of all. The pre-service earth science teachers having wrong prior knowledge selected inappropriate resources, as well as fell into the error of concept connecting. The pre-service earth science teachers having right prior knowledge partly considered only shape of resources, but had a disregard for formation process of it in material making. Accordingly, we need to reflect richly Geological Field Trip and Solid Earth Science to curriculum for earth science teacher education. And we have to educate pre-service earth science teachers to create holistic concept on the geological subject matter knowledge, field based teaching and learning strategy, material making process.

Science museum are the typical channels for students to experience science as outside school science lessons. Hereupon, in this study, middle school earth science contents system and achievement standards by the 7th Curriculum analyzed exhibit of science museum for basis. As a result, relevance between accomplishment level and Exhibition was insufficient in curriculum, and the area of geology in the exhibition overemphasized. Therefore, exhibit that consider curriculum is required. hereafter, Result of this study presents display of science museum and direction of education.

현대 교육은 단순한 암기 위주가 아닌 첨단 컴퓨터를 이용한 실험 실습 위주의 직접 보고 듣고 느끼는 방향으로 진보하고 있다. 실험 실습에 의한 과학교육은 사용자의 탐구능력 향상과 과학적 태도 향상에 중요한 역할을 하게 될 것이며 기존의 암기위주나 단순한 수치에 의한 개념 학습을 탈피하여 Data collection 기술과 분석의 활용을 통해 사용자가 과학을 좀 더 이해하고 사용할 수 있도록 하는 능력을 증진하게 한다. 이를 위한 과학교육의 한 방법으로 MBL(Microcomputer Based Laboratory)은 실험자가 실험실이나 야외에서 각종 기구를 사용해 데이터를 습득할 수 있도록 도와주는 컴퓨터 기반 과학 실험 시스템으로서 미국, 영국 등 과학 교육 분야에서 추구하고 있는 세계적인 추세라고 할 수 있다. 이러한 MBL 시스템의 구성은 센서를 통해 얻어지는 자료를 컴퓨터에 전달하는 매개체인 인터페이스, 과학 실험에서 발생하는 데이터를 직접 전기적 신호로 변환하여 인터페이스에 전달하는 센서, 인터페이스에서 전달되는 전기적 신호를 컴퓨터 화면에 나타내어 주는 컴퓨터용 전용 프로그램으로 구성된다. 이러한 MBL을 과학교육에 활용한다면 학생들이 스스로 과학적으로 탐구하고 문제를 해결할 수 있는 능력을 배양하는 데 많은 도움이 될 것이다.
