History of science (HOS, hereafter) has been considered as a useful tool for achieving a variety of objectives in science lesson. The purpose of this study was to develop three dimensional framework for effectively analyzing HOS content in science textbook. In addition, using this framework, we analyzed HOS content in science textbooks of the 7th curriculum by focusing on the history of Earth science. Developed framework consists of three dimensions; instruction context, role, and type. Each dimension has several sub-domains. The results of textbook analysis revealed that science textbook didn't include diverse HOS materials that are appropriate to three dimensions and its sub-domains of the framework. Based on the results, we proposed that three dimensional framework is an effective tool to develop materials for teaching and learning materials of HOS with multiple coordinations of various contexts and purposes.

The purpose of this study is to develop a sample chapter of mathematics textbook at the first middle school according to the model of supporting learners' self-directed learning. The self-directed learning is a learning strategy to develop learner's ability to solve unstructured problems by himself or herself. Basically, the textbook should included learning objectives distinctively. Second textbook should consist of some appropriate method for learners to learn content. Third, it suggests some plans to utilize learning strategies of this model effectively when authors or developers develop textbooks in future. Based on those condition, it is also requested that the sample chapter of the textbook be develop in order to study interestingly as well as to implement self-directed study, and content materials using mixed diverse subjects would be included in the chapter. Furthermore, the sample chapter which is suitable to the semester of managing self-directed learning middle school would be developed. For this purpose, in this study the 'Plane shapes' was selected dealt with in the first middle school. The sample chapter is developed at first by the researchers and then revised and completed through the checking from the professionalists two times.

The purpose of this study is to extract the conceptual nature of contextualization in mathematical problems and to analyze problems according to its conceptual framework based on the perspective of RME (Realistic Mathematical Education) which emphasizes mathematising through realistic context in mathematics textbooks of the 4th grade in Korean textbooks and the U. S. materials. "Contextualization" was analyzed by three elements such as everydayness, variety, and mathematical immanence. As results, Korean textbook showed much less in the amount of contextual problems and also represented lower contextualization in contextual problems than that of American textbooks.

In this study, an implication has been drawn for the textbook development and teaching and learning process as a congruence of a figure is compared and analyzed between Korean elementary mathematics textbooks and American elementary math textbooks. Based on the result of comparison and analysis in congruence contents between Korean and EM textbooks, some applications for the development of figure and congruence chapters in Korean textbooks are as below. First of all, in term of congruence, activities related to congruence need to be introduced after the concept of congruence is defined either with illustrations of fundamental figures such as a segment and angle or with examples of polygon. Second, it is required to assist students to realize that compasses can be used to copy length. In Korean textbooks, compasses are being introduced as a tool to draw circles, which causes children to have difficulty in drawing triangles. Last, for the implication of congruence, tessellation suggested in American Everyday Mathematics textbooks is worth being applied to the development of Korean textbooks.

"SMART" is a word to condense a new kind of educational system recently proposed by the Korean government. It signifies an intelligent adaptive learning system to innovate the educational environment, the contents, methodology and assessment. Developing a digital textbook was one of the main strategic goals to drive forward "smart" education. The Korean government expected to finish the development of digital textbooks of science, mathematics, social studies and English by 2013 and to have a field experiment for them in 2014. However, the case of mathematics was postponed for an indefinite period because its draft version was no different from a traditional textbook in its functional aspect. This situation might come from the non-existence of a good authoring tool and an inexperienced sense by developers of the opportunities available with digital textbooks. This paper introduces the main features for developing a digital mathematics textbook for the 12th grade students, which was developed in the environment of Cabri LM as an authoring tool. This paper also looks upon the results of a whole lesson using the textbook in managing the classroom interaction with students.

디지털 교과서 상용화 시범 사업은 다양한 학습 지원 도구들과 사회 각 분야의 최신정보, 지식DB등을 활용하여 교실에서 참여형 학습을 실행할 수 있는 사업이다. 현재 디지털 교과서는 유통되고 있는 페이지 단위의 e-book형태가 아닌 확장 가능 구조로 개발되어 있어, 기존의 e-book 단말기나 e-book reader 프로그램에 바로 적용할 수 없다. 본 연구는 이러한 문제를 해결하기 위해 디지털 교과서 단말기의 요구 사항과 기존 단말기의 구현기능을 분석하여, 개선된 단말기의 기능과 규격을 제시하고, 이를 활용할 수 있는 교실 교육 환경을 제안한다.

This paper provides a description of the process in development of textbook unit on measuring length for second grade in elementary school according to action research methodology. The teaching unit development has been done based on the new national mathematics curriculum released in 2006. Mathematical communication and positive attitude toward mathematics are highly emphasized in the new curriculum. These new foci have been analysed through literature review and interviews with two incumbent teachers to be respected in the unit in an appropriate way. Three stages of development with different ways of organizing contents and different problem contexts were reported in the paper.

The purpose of this study is to comparatively analyze the internal and external frameworks of elementary science textbooks, which first appeared as the authorization system of elementary science textbooks changed from the national government system. In order to confirm the purpose of the authorization system to support the development of diverse and creative textbooks, this study compared 7 authorized textbooks with the national textbook developed as the 'Use of Magnets' unit of the 2015 revised science curriculum. In this study, the textbook's framework was largely divided into an external framework and an internal framework for the 'Use of Magnets' unit of elementary science textbooks, and quantitative and qualitative analyses were conducted in parallel according to each subcategory. According to the research results, in the external framework of textbook units, all textbooks had the same structure: unit introduction, scientific inquiry, creative convergence, unit arrangement, and scientific reading materials. The framework in the 'Use of Magnets' unit of the 7 types of authorized textbooks was found to have some differences according to the textbook development team's interpretation of the curriculum achievement standards and many commonalities that maintained the framework in the national textbooks. In addition, the characteristics of each textbook were clearly revealed in some areas not specified in curriculum such as unit introduction activities and science reading materials, a meaningful change was also found in that the level of inquiry activity was classified and operated in response to the uniform inquiry activity operation of the existing government textbooks.

In this paper, we research into an effective operation environment of digital textbook according to the adaption of an electronic textbook and analyze the approval program and the authorization program of the paper textbook for the efficient utility of a digital textbook. We propose various criterions and methods of the approval and authorization program. Finally, we show the whole process of the proposed approval and authorization program. We hope that our study apply to the standard approval and authorization program of the Ministry of Education.
