This paper analyzed the programming education specialized lessons presented in two types of elementary school mathematics textbooks according to the revised Japanese curriculum in 2017. First, this paper presented in detail how each activity is connected to Korean mathematics areas, what elements of mathematics can be learned through programming education, how each activity is structured, and how the actual programming according to the textbook activities is structured. In Japanese textbooks, geometry and measurement areas were presented the most among Korean mathematics content areas, and mathematical elements such as sequences, rules, and algorithms were most implemented for learning. Digital learning tools that make up actual programming present more elements than those presented in the textbooks and are presented in great detail so that students can do actual programming. Lastly, in blocks, motion, control, and calculation blocks were used a lot. Based on these research results, this study provides implications when conducting programming-related education in Korea.

This study aimed to analyze the learning contents related to biotechnology in life science II and general engineering based on the 2015 revised national curriculum and discuss pedagogical implications for biotechnology education. The main findings were as follows: First, while the learning topics of life science II focused on the ethical aspects related to biotechnology, the learning topics of general engineering focused on the industrial aspects of biotechnology. Second, there were types of overlapping biotechnologies in the life science II textbooks and general engineering textbooks. However, the life science II textbooks provided more scientific and professional descriptions of biotechnology principles than the general engineering textbooks. Also, the life science II textbooks provided more specific overall explanations than the general engineering textbooks. There was a lack of ethical considerations concerning biotechnology in the general engineering textbooks. These findings imply that it is necessary to reorganize biotechnology content based on each school's curriculum and student characteristics.

The purpose of this research is to analyze cognitive demands, answer types, and storytelling types on the basis of mathematical tasks in five different mathematics textbooks based on 2009 revised curriculum in order to suggest directions for the development and use of storytelling mathematics textbooks in school. Results show that first, PNC (Procedures without Connections) task was the largest category in cognitive demands of all mathematical tasks, Low-Level task was larger than others in cognitive demands of mathematical content tasks, and High-Level task was larger than others in cognitive demands of mathematical activity tasks. Second, a short-answer type was the largest category in answer types of all mathematical tasks, the majority of mathematical content tasks were a short-answer type, and the majority of mathematical activity tasks were both short-answer and explanation-answer types. Finally, storytelling connected to real-life was the largest category in storytelling types, and the number of mathematical activity tasks was less than that of mathematical content tasks. However, in the tasks reflected on storytelling, the percentage of mathematical activity tasks was higher than that of mathematical content tasks. Based on the results, while developing storytelling mathematics textbooks and using storytelling textbooks in school, it suggests to consider the need for balance and diversity in cognitive demands, answer types, and storytelling types according to mathematical tasks.

This study selected the objects and the content factors of multicultural education in home economics, and analyzed multicultural contents reflected on high school technology & home economics textbooks. Based on these results, this study suggests the direction for improving technology & home economics textbook. We set up the object of multicultural education in home economics as creating the new culture through developing multicultural ability by critical thinking. The distribution analysis of multicultural contents of six kinds of technology & home economics textbook resulted that most of contents are assigned to 'knowledge section'. And 'personal relationship and group function' holds the highest ratio among the sub-sections of 'function section'. The 'value section' shows even distribution in its sub-sections. Most of textbooks contain characteristics of Korean traditional culture and necessary value in multicultural society. But, there are lack of contents about the way of communication with other cultures and coexist with diverse cultures. When we develops new textbook hereafter, it is necessary to contain the contents about which can help to understand and respect diverse culture through the egalitarian perspective and, by extension, which can make students think critically about the attitude, values, environment and way of live together with multicultural members in society. From now on Home Economics education will help the students who live in multicultural society to be understand about the differences in diverse culture and to create a desirable culture through the critical thinking as well.

The purpose of the study was to research science gifted students' learning styles and perceptions on subject matter content. The data was collected from primary science and mathematics classes of a University Center for Science Gifted Education, science classes of a Metrocity Primary Gifted Education Institute, and classes of a normal school. The results of the study were that gifted students perceived the school curriculum much easier than non-gifted students did, ($X^2(4)=33.180$, p<.001), and that levels of interest in the content did not differ between the groups, but 34.6 percent of the total students responded that they found the content uninteresting. Gifted students did not see the content as being important compared to the non-gifted students, ($X^2(4)=12.443$, p<.05), and gifted students valued the methods used higher than the actual content of the textbook. The most helpful activities for their teaming that gifted students chose were projects, listening to teachers, and conducting experiments, amongst others. They also preformed 'teaming at their own speed in a mixed group'" for the study of social studies, science, and mathematics, whereas non-gifted students preformed teaming at the same speed. The two groups of science gifted students varied especially in their perceptions of most helpful activities. It is suggested that special programs for fulfilling gifted students' needs and abilities need to be developed and implemented.

The purpose of this study was to find out how much home economics(HE) textbook was focused on what kind of factors in career education, by analyzing the HE textbooks from the 7th grade(1st grade of the middle school) to the 10th grade(1st grade of high school), which were developed by applying the 7th educational process. 12 textbooks which were published by three publishers were randomly selected by grade. This study used the instrument developed by Korea Research Institute for Vacational Education & Training(2001) as an analysis frame, along with a content analysis system. The results of this study were as follows. The publishers of HE textbook stressed similar points in each section of career education, evenly reflecting the objectives and contents of career education. Three kinds of publishers also placed the same weight on the factors of career education in each unit, and suggested the contents related to career education in the whole units. HE textbook was designed to lead learners to understand self and have interest in varied occupations. Additionally, it provided the learners with a chance to consider their career and occupation by means of detailed job information, and its contents including learning of occupational ability for job selection were useful to plan and prepare for career. Accordingly, as HE textbook is most effective to promote connection between work and learning and contains proper factors of career guidance, it is one of the most appropriate textbooks to deal with career education.

This study explores classes for pre-service mathematics teachers. The purpose of this study is to examine the differences between 'non-face-to-face' classes & 'face-to-face' classes, as well as the differences in learning outcomes between these two methods. A Professors' Learning Group was formed to effectively carry out this study. Through this learning group, we shared how to plan and operate the lecture. The subjects of this study are 'non-face-to-face calculus courses & face-to-face calculus courses' and 'non-face mathematics education theory courses & face-to-face mathematics education theory courses." Specifically, in these two pairs of courses, we analyze the differences in course management and the differences in the outcomes of students' assessments. Non-face-to-face classes were planned, developed, implemented and evaluated based on the 'non-face class design model.' The results of this study are as follows: First, we explored the differences between 'non-face-to-face classes/mixed classes' and 'face-to-face classes.' Second, the achievement results in calculus courses were higher in face-to-face classes than in non-face classes. Third, the results of achievements in mathematics education theory courses were higher in mixed classes than in face-to-face classes. Through the results of this study, we hope that the non-face-to-face class capabilities can be improved in pre-service mathematics teacher training.

The purpose of this study is to propose the curriculum of consumer life field in Home Economics Education(HEE) to raise people who practice 'ethical consumption'. For this purpose, this study established the concept of ethical consumption through an academic review of the concept of ethical consumption first. Ethical consumption is to the practice of consumption that fulfills personal and social responsibilities to change human life happily. In this study, we find out how the consumer life area in the HEE curriculum has been educated and we propose how to teach the content of ethical consumption in HEE curriculum by critically examining the content of ethical consumption presented in current HEE textbooks First, in the HEE curriculum, the contents of the consumer life field have been presented since the first curriculum, and the qualitative change has gradually been made as the concept of the consumer culture, but responsible consumption and ethical consumption are not properly reflected in the education and the summit. Second, the revised HEE textbooks of 2015 is necessary to present concrete method of ethical consumption practice because it lacks definite definition of ethical consumption and presents only general contents. Third, the direction of HEE curriculum for ethical consumption practice is responsible and the goal of HEE curriculum is to raise awareness of social responsibility for ethical consumption practice. The contents of HEE curriculum for ethical consumption practice should be included in consumption and consumption, sustainable consumption, and ethical consumption.
