The purpose of this study was to survey junior high school teachers' and students' perceptions on the science textbooks. Subjects of this study were 113 science teachers and 715 students from junior high schools in Daegu and Kyungpook area. As statistical method, one-way ANOVA and t-test were used to check differences of the perceptions between teachers and students. Teachers had different perceptions by school location and class size, while students had different perceptions by school location, co-ed, class size, and grade level. Both teachers and students having the relativistic viewpoint on textbook knowledge regarded the knowledge as relativistic one, and preferred the student-centered textbooks. Teachers liked textbooks written by the student-centered view more than students did. Teachers had the more absolutistic viewpoint on textbook knowledge and on teaching, while students liked the electronic textbooks more than teachers did.

The purpose of this study is to analyze tasks reflected in Korean and US textbooks according to the mathematical modeling perspectives, and then to compare the diversity of learning opportunities given to students from both countries. For this, we analyzed mathematical modeling tasks of textbooks based on three aspects: mathematical modeling process, data, and expression. Results are as follows. First, with respect to modeling process, Korean textbook provides a high percentage of the task at all stages of modeling than US textbook. Second, with respect to data, both countries' textbooks have the highest percentage of matching task. Korean textbooks have a large gap in data characteristics by textbook. Third, with respect to expression, both countries' textbooks have the highest percentage of text and picture. Korean textbooks have a large gap in the type of expression than US textbooks, and some textbooks have no other expression except for text and picture. Fourth, tasks were analyzed by integrating the three features. The three features were not combined in various ways. It is necessary to diversify the integration of the three features.

According to the Digi Capital forecast, the global augmented reality market is expected to grow rapidly by 2020 to reach 150 billion dollars. In particular, high value added effects are expected in education. As ICT advances, digital textbooks are also leading innovative education by adding interactive functions. Advanced countries, including the U.S., are already using digital textbooks that use augmented reality technology in their classes. In line with this technological outlook, the ministry proposed a design plan that applies augmented reality technology to middle school science 1 digital textbooks. A study on middle school science 1 digital textbooks showed that each unit provided short videos. In addition, an investigation into the augmented reality class case showed that it was difficult to establish experimental equipment, lack of equipment (devices), and 3D design contents that did not continue despite the excellence of learning effects. Based on this demand, we designed an augmented reality scenario and system configuration to be applied to the instrument-specific experiments of middle school science 1 digital textbooks to explore and explore the contents of augmented reality by students. This research will replace the dangerous experiments and time consuming experiments for teachers and students by applying augmented reality to science subjects that are essential for the development of digital textbooks.

This study analyzed the mathematics textbooks of middle grades in the first Korean curriculum, based on the modern trends of mathematics education curriculum, comparing with present Korean curriculum's other textbooks and the American textbook, MiC. The mathematics textbooks in the first Korean curriculum are based on various situations in our real life and introduce mathematical concepts throughout a set of mathematics problems. The textbooks present mathematical concepts with connected knowledge and include mathematical activities which make students use mathematical table, graph and formula at the same time. And students are actively required to discuss together during the mathematics problem solving process. As the results of this modern review on Korean 1st curriculum and middle grades mathematics textbooks, it would provide preliminary data and meaningful implications for the next curriculum and concomitant instructional materials.

To respond to the announcement of the revised version of science curriculum early this year, it has been necessary to develop new science textbooks which can be appropriate and effective to achieve the goals of the revised curriculum. The system of new textbooks needs to embrace the concerns of cognitive development in scientific knowledge, skills, and attitudes as well as social and cultural demands in the rapidly changing society. To develop an innovative framework of science textbooks, we examined previous studies on textbook analysis in Korea and analyzed science textbooks in the United States, Singapore, and Japan. We analyzed various ways of introducing and developing conceptual knowledge, leading scientific inquiry skills and process, enhancing scientific attitudes toward science, technology, society and the environment in those science textbooks. In the process of framing the structures of textbooks, we focused on ways of increasing educational effects of visualized texts, leaners' interest, user-friendly procedure, scientific inquiry, effectiveness of hands-on activities, scientific reading and writing skills, and usage of workbook. Based on those aspects and analyses of textbooks, we attempted to propose a feasible framework of Grade $3{\sim}4$ Science textbook which can effectively respond to the educational changes and demands in the local and global society.

The purpose of the study is to compare elementary school science textbooks ($3^{rd}$ grade) in Korea and the U.S., centering on the ways to present scientific concepts and inquiry process in the units of 'matter.' The analysis is focused on: a) general structure of the units; b) how to present scientific concepts in terms of its connections and complexity; c) how to present inquiry process in terms of its types and skills. The findings of the study are as follows. First, the contents of 'matter' units are scientific discipline-based in both countries. The general structure of the units in Korean textbooks is unrestricted compared to those in the U.S. Second, the connections among the concepts are poor and the level of complexity is low in Korean textbooks, which are contrary to those in the U.S. textbooks. Third, it is a common feature that the inquiry process is based on learners' everyday experiences with simple experiments in two countries' textbooks. However, the inquiry process in the U.S. textbooks is provided with detailed instructions while the process in Korea is presented with diverse activities without formal guidelines. Based on the results, the study suggests three recommendations to improve Korean textbooks: a) science contents should be linked to other disciplines in order to promote practical applications; b) scientific concepts are required to be tightly connected and provided with in-depth explanations; c) inquiry process is needed to be presented with specific guidance to facilitate scientific thinking.

The contents of fraction division in textbooks are important because there were changes in situations and problem solving methods in textbooks according to the revision of the curriculum and the contents of textbooks affect students' learning directly. So, this study analyzed the achievement standards of the curriculum and formula types and situations, and the introduction process of non-standard and standard algorithms presented in Korean mathematics textbooks. The results are follows: there was little difference in the achievement standards of the curriculum, but there was a difference in the arrangement of contents by grades in textbooks. There was a difference in the types of formula according to textbooks. And the situation became more diverse; recent textbooks have changed to the direction of using the non-standard and the standard algorithm in parallel. In conclusion, I proposed categorizing rather than splitting the types of fraction division, the connection of non-standard and standard algorithm, and the need to prepare methods to pursue generalization and justification according to the common characteristics in the process of introducing standard algorithm.

Ratio and rate are key topics in the area of 'Patterns', but there are various perspectives on them. This study compared and analyzed the perspectives of Korean and Singaporean mathematics textbooks on ratio and rate, and explored how teaching and learning methods develop according to each perspective in terms of quantitative reasoning. To this end, we reorganized the analysis criteria based on some studies, and analyzed the textbooks of the two countries in relation to context, relationship, and representation. The results of the study are as follows. Regarding the context, there were differences in the situations, types of units and use of units of the problems presented in textbooks. In terms of relationship, there were differences in the types of two quantities and relationship of quantities. Lastly, there were differences in the representation of ratio and rate. Through these results, we found that elementary mathematics textbooks in Korea and Singapore take different perspectives on ratio and rate. In particular, the perspective taken by Korean textbooks on ratio and rate had unique points different from that of other previous studies. Considering this Korean perspective, we suggested some implications that could help improve textbooks related to ratio and rate and teach them meaningfully.

The purpose of the study were to analyze of the curriculum and textbooks for technology & home economics in the 7th national curriculum, and to suggest the revision direction of them. This study was carried out through literature research of national curriculum and textbooks of Korea and Japan, respectively. The findings of the study were as follows: First, we have three textbooks which are technology & home economics 1, technology & home economics 2, technology & home economics 3 for each grade of middle school student, but one technology textbook and one home economics textbook may be better for middle school student to reduce the learning content following revised curriculum. Second, as an aspect of learning content between technology textbook and computer textbook, the computer and information volume is too much overlapped, which is also the same result at the survey research report of KICE. Therefore, the computer content of technology & home economics textbooks must be considered to reduce according to follow research.
