In this study, science teachers' perception and attitude toward nanotechnology are examined through questionnaires gathered from 134 secondary science teachers. As a result, the study shows that science teachers have high perceptiveness. However, they do not understand specific information on nanotechnology correctly. Science teachers have positive attitudes toward nanotechnology and they have perceived risks of nanotechnology as well as benefits of nanotechnology. Science teachers show positive attitudes toward the application of nanotechnology, whereas they show negative attitudes toward personal information chip and nano-taste enhancer. Science teachers are exposed to nanotechnology via various sources such as TV and internet, whereas teachers rarely get information on nanotechnology-related concepts in textbooks and teaching resources. Science teachers have perceived many textbooks do not introduce enough nanotechnology-related concepts. Many teachers try to explain the nanotechnology when textbooks include nanotechnology-related concepts, whereas quite a few of teachers do not introduce the nanotechnology-related concepts in class.

Experiment is recognized as an important part in science and science education. Scientists do experiments for verifying or refuting theory and they take many forms to do experiments. One of the central goals of science education is to improve inquiry ability. So we have taken for granted that students engage in authentic inquiry and experiment which scientists carry out to research. But it is not always positive about discussions and opinions what school experiment and its role is in learning science and understanding about science. There is certainly a gap between experiments which scientists and students do even though there is a theoretical basis of school science experiment. In this study, we discussed how scientific inquiry and school inquiry are different, and what it means to use instrument in school science experiment. And as a case, we analyzed chemistry experiments in science textbook and manipulation level of instruments which were handled in chemistry experiments, we shed light on the meanings of experiments and instruments in school science inquiry based on the result of experiments and instruments analysis.

The purpose of this study was to identify the proper identification method of the gifted students in math and science. The subjects were 6,237 students from 3rd to 7th graders. The subjects took nation-wide tests which were made for identifying the gifted students. The tests were composed of creativity, thinking skill, and academic achievement in math and science. The results of this study were as follows; First, creativity and thinking skill were positively correlated with the academic achievements. Specially, the academic achievement of science was positively correlated with the all of the sub-factors of creativity and thinking skill variables. Second, the influential power of each variable differed depending on the identification methods. Also, group 1, which was considered all variables such as, creativity, thinking skill, and academic achievement, was the most proper way to identifying the top 1% students from the subjects. These results implies the variables of creativity, thinking skill, and academic achievement have to consider identifying the gifted students in math and science.

In the era of the 4^th industrial revolution and convergence, various discussions and studies have been conducted to develop future social talents, and through this, the need for creative convergence talents is increasing. In line with the change to a software-oriented society, countries around the world are trying to strengthen SW education, but high school students' awareness of the necessity of information subject and SW education that is the center of convergence is insufficient. Therefore, opportunities for convergence of the information subject and various fields should be provided. In this study, information education was converged to the science exploration experiment subject to construct an educational program that can develop creative convergence, and a convergence class using physical computing were applied to high school students for 9 hours. As a result of the experiment, the recognition of SW education of the experimental group was improved, and it was confirmed that the learner's convergence literacy of the experimental group was statistically different from that of the control group that conducted the general science experiment class.

This study is to investigate the level and connection of learning concepts related to metabolism presented in life science textbooks developed according to the national common basic curriculum. One kind of elementary school, and three kinds of middle school and high school science textbooks were analysed. The gross number of concepts related to metabolism was 42 in elementary, 149 in middle and 126 in high school science textbooks. The number of concepts was much more different by school than by publisher. Ratio of the number of concrete versus formal concepts decreased gradationally by grade, but the number of learning concepts increased radically by grade. Thus, it is implied that science learning concepts are presented considering the number of concepts as well as cognitive level of learner, and unit and content are constructed on the connection among them in developing science curriculum and textbooks.

The concept map is the diagram of two dimensions which hierachically arrays main concepts from those of the textbook and shows their relations. The research analyzed five of the ten high school earthscience textbooks approved by the Minister of Education according to the 6th reformed curriculum in 1995, one of which this research chose to make out the concept maps. The chapter [III. the Universe] contains the outer space of the earth presents new concepts about the stars and the universe and introduces the latest research in astronomy. This study changed textbook contents into Novak's concept map, searched for concepts requiring complement for learners in oder to obtain concepts from those of the textbook and pointed out problems on the basis of that result still better concept map is set up. We have the following conclusions. First, it is necessary to rule out unnecessary small units so as to make more effective understanding and to rearrange the units to have relation to contents. Second, the higher concept and lower concept need to be rearranged systematically in making an array of textbook contents. Third, the concept should have something to do with learners' experences and consciousness by showing learners the real examples relevant to the concept for the link between them.

This study classified the visualization's materials presented in two types of middle school science textbooks to data visualization and infographics, thereafter characteristics of infographics according to science content's domains were analyzed using an analytical framework for infopraphics. The results of this study are as follows : First, visualization materials in middle school science textbooks had more data visualization (23.2%) than infographics (76.8%). Second, there were many differences in information content's category among the science subject's domains. The relationship type of information content in the domain of energy and matter, the function type in life domain, and the location type in the earth domain were prominent. In visual representation's category, the illustration type and comparative analysis type were the most dominant in the all science domains. The horizontal type in layout category occupied the largest proportion in all science domains. Therefore, it is necessary to present the visualization materials with the infographics conveying many informations than the data visualization in middle school science textbooks. And the infographics need to be developed and distributed in various formats in each science domain.

"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.

The purpose of this study is to present the development direction of future reading education by examining the characteristics of reading materials within the high school textbook developed as the 2015 revised curriculum. For this purpose, reading materials of high school textbooks were analyzed in Korean language, mathematics, English, integrated science, and integrated social studies. The analysis criteria of reading materials were subject type, purpose, and student activities. As a result of the study, reading materials on various themes such as humanity, liberty, culture, environment, and district were presented in the integrated society and integrated science textbook of the 2015 revised curriculum. In particular, the Korean language curriculum was composed of a unit called "reading one book in one semester". However, most reading materials have no guidance on reading effective or reading direction, and lack of reading materials and information for extended reading. The reader's reading of the textbook was found to be simply supplementing the learning content of each unit or presenting fragmentary cues for conceptual purposes. This suggests that there is a lack of awareness of students' interest in reading, internalization of reading, and extension of reading. In this paper, we suggest supplementary materials of reading materials for expanding the high school textbooks, and explore the developmental relationship between textbooks and reading education through suggestions on aspects of textbook composition and teaching methods.
