The School Curriculum amend in 2007 mandates the contents from which students can learn the principles and concepts of computer science. Computer Science is one of the most rapidly changing subjects, and the Informatics textbook should accurately explain the basic principles and concepts based on the latest technology. However, we found that the middle school textbooks in circulation lack accuracy and consistency in describing CPU. This paper attempted to discover the root-cause of the fallacy and suggest timely and appropriate explanation based on the historical and technical analysis. According to our study, it is appropriate to state that CPU is composed of datapath and control unit. The Datapath performs operations on data and holds data temporarily, and it is composed of the hardware components such as memory, register, ALU and adder. The Control unit decides the operation types of datapath elements, main memory and I/O devices. Nevertheless, considering the technological literacy of middle school students, we suggest the terms, 'arithmetic part' and 'control part' instead of datapath and control unit.

The purpose of this study is to explore alternative ways of teaching derivatives in a way that emphasizes intuition. For this purpose, the contents related to derivatives in Korean curriculum and textbooks were analyzed by comparing with contents in Singapore Curriculum and textbooks. Singapore, where the curriculum deals with derivatives relatively earlier than Korea, introduces the concept of derivatives and differentiation as the slope of tangent instead of the rate of instantaneous change in textbook. Also, Singapore use technology and inductive extrapolation to emphasize intuition rather than form and logic. Further, from the results of the exploration of other foreign cases, we confirm that the UK and Australia also emphasized intuition in teaching derivatives and differentiation. Based on the results, we discuss the meaning and implication of introducing derivatives and teaching differentiation in a way that emphasizes intuition. Finally, we propose the implications for the alternative way of teaching differentiation.

This study investigated and analyzed the social and emotional learning components of middle school science, and high school integrated science and science inquiry experiments, which are common subjects that all students must complete. The subjects of analysis were 139 achievement standards of science and curriculum and 496 activities included in textbooks. The research results are as follows. In the case of curriculum achievement standards, 'cultural understanding' was hardly included among the seven science and social-emotional learning elements, 'numeracy' and 'creative thinking' appeared high in middle school, 'critical thinking', 'social technology' and 'ethical understanding' were included with high frequency in high school. And in the case of textbook activity, the tendency of social-emotional learning elements in middle school and high school was similar. 'critical thinking', 'creative thinking', and 'social skills' were mainly provided, while 'ethical understanding' and 'cultural understanding' were reflected in a limited way. In order to cultivate the elements of overall social-emotional learning, it is necessary to specify the achievement standards of the curriculum or to supplement the textbook activities and teaching-learning process.

The purpose of this study is to analyze the relationship between home economics curriculum and media literacy education. For this purpose, 12 kinds = types of learning materials for middle school 'Technology·Home Economics 2' textbooks were analyzed. After selecting 'Media Literacy Performance Goals(MLPG)' as the basis for analysis, the distribution of media data and reflection of MLPG were analyzed by frequency and content analysis. The results of this study are as follows. First, 39.6% of the learning materials using media materials out of the total learning materials of 12 textbooks, and there were differences in the frequency and weight of learning materials using media materials by publishers. Depending on the type of media, 68.3% of 'printing', 16.7% of 'images, video', 13.5% of 'digital', and 86.5% of the use of unidirectional media. Second, there was a difference in frequency and weight of learning materials reflecting the MLPG by publishers, and it was necessary to supplement the learning content to improve overall media literacy. Among the MLPG reflected in the learning materials, 'meaning and communication' was the most reflected performance goal, with 58.8%, but there was no two-way communication through the media. Based on the results of these textbook analysis, MLPG in Home Economics are revised as follows. 'Understanding the meaning and self-expression', 'Communication and social participation', 'Use of responsible media', 'Appreciation and enjoyment', 'Use of media technology', 'Information search and selection', 'Creation and production', 'Critical understanding and evaluation'.

The purpose of this research study was to examine how multi-cultural education contents are reflected in the contents related to the 'Human Development and Family' area of middle school Technology-Home Economics textbooks, based on the multi-cultural education criteria developed by Paek(2014). The sample of the study consisted of the 'Human Development and Family' contents in 'Technology-Home Economics 1·2' textbooks from five publishers (10 volumes) written in accordance with the 2015 revised curriculum. The research results of the study can be summarized as follows: First, all the four multi-cultural education criterion components were shown in the textbooks from five publishers. Cooperation was shown in the highest frequency, followed by Identity, Diversity, and Equality. Second, the analyses of text, image, and learning activities in the textbooks confirmed that Home Economics as a subject contains multi-cultural education contents that allow students to establish self and identity, respect others, accept diverse family patterns, understand family changes from multiple viewpoints, and form family community culture from gender equality perspective without prejudice. Ultimately, it can be concluded that Home Economics is a subject that enables learners to learn how individuals and families can cooperate and care for each other in order to harmoniously coexist.

In 2014, third and fourth graders in primary schools will start using digital textbooks for social science, science, and English. Fifth and sixth graders will follow the next year. Given this situation, this study investigated the awareness of digital textbooks by primary school teachers who did not have direct experience with digital textbooks. Also studied was the teachers' acceptance of digital textbooks, based on the Technology Acceptance Model. The results showed that most respondents were not ready to use digital textbooks, and they were apprehensive about their use. However, if the teachers were required to use digital textbooks, usefulness and playfulness were key factors in their acceptance.

It is necessary to use industrial oriented equipment, as well as lecturer who has field experience, textbook and materials for engineering education which meets the change of industrial technology. Current education equipment is composed of general purposed equipment which are used for teaching with ease and convenience instead of field oriented achieving technology. The leads to failure of engineering education to keep up with the change of industrial technology, making engineering education stay far away from field oriented education. This study looks at the case of development of education equipment which takes an important role in engineering education, and suggests the ways of development and utilization of engineering education equipment by analyzing the effects of education when the equipment are used in the education.

The "Information and Communication Technology Education Guidelines" was revised in December, 2005. However, students are still not taught the contents in the "Information and Communication Technology Education Guidelines Rev." and are not taught the contents in the "Understanding of the Information Processing" area among them in particular. Therefore, we analyzed the contents in the "Understanding of the Information Processing" area of the elementary ICT textbooks published on and after June 2006. In the result, the contents of many textbooks are not based on the "Information and Communication Technology Education Revised Guidelines" and programming languages using elementary school are too many. The revision of the elementary ICT textbooks must be settled without delay and the certification systems of elementary ICT textbooks must be improved.

It is necessary for lower grade students to study the correct usage of tools as a base of the technical education for dismantling and assembling various machines. However, enough understanding has not been obtained though the usage of these tools when training first grade students. So, we started to develop a teaching text and materials within the students' practice curriculum based on the dismantling and assembly of all-terrain vehicle [ATV]'s, which is a very motivating for lower grade students. This practice makes the student learn both how to use the tools and the steering mechanism of cars through the dismantling and assembling of the ATV. It is possible to not only have the student learn about the knowledge obtained through the practice, but also they also acquire wider and deeper knowledge through making the text and teaching materials for the practice. The textbook and secondary educational materials of this practice curriculum were created in cooperation with a fifth grade student as part of their graduation research. As a result, an effective teaching and learning text and secondary educational material regarding manufacturing practice could be developed from the student's point of view. Making a teaching text and materials is effective for promoting the study and experience of engineering.

This paper presents a method of using syntax and shallow semantic analysis for Vietnamese question generation (QG). Specifically, our proposed technique concentrates on investigating both the syntactic and shallow semantic structure of each sentence. The main goal of our method is to generate questions from a single sentence. These generated questions are known as factoid questions which require short, fact-based answers. In general, syntax-based analysis is one of the most popular approaches within the QG field, but it requires linguistic expert knowledge as well as a deep understanding of syntax rules in the Vietnamese language. It is thus considered a high-cost and inefficient solution due to the requirement of significant human effort to achieve qualified syntax rules. To deal with this problem, we collected the syntax rules in Vietnamese from a Vietnamese language textbook. Moreover, we also used different natural language processing (NLP) techniques to analyze Vietnamese shallow syntax and semantics for the QG task. These techniques include: sentence segmentation, word segmentation, part of speech, chunking, dependency parsing, and named entity recognition. We used human evaluation to assess the credibility of our model, which means we manually generated questions from the corpus, and then compared them with the generated questions. The empirical evidence demonstrates that our proposed technique has significant performance, in which the generated questions are very similar to those which are created by humans.
