The goal of vocational school is to provide students with basic skills and help develop them to have satisfactory careers. With the knowledge they have learned, it helps them to find their interests and aptitudes when they graduate. The government is putting a lot of effort into clarifying the goal accomplishment and the vision proposals of vocational schools, and the structure-oriented guidance controlled by the government is thought to be very influential to the social structure and individual perceptions. Social stereotypes(discrimination) and perceptions that can be the core of a social structure need to be transformed for people to be fulfilled in their careers in the upcoming advanced Korean society. The important solution is to form correct values and a system of career selection which can ensure a stable future for students. Therefore, to carry out research regarding training human resources in terms of students from vocational schools' landscape architecture majors in an approaching method with a new perspective, we analyzed education plans from vocational schools in 11 regions, textbooks used in common, governmental publications regarding career education policies of vocational schools and questionnaires from students who are majoring in landscape architecture at vocational schools. As a result, we were able to find out the types and the frequencies of career-occupation education at each school through analysis of education plans and the necessity to control the amount and the level of the contents for high school students to have careers in analyzing textbooks. In addition, in Ministry of Education, Science and Technology's analyzing career education policies of vocational schools, we figured out the government's policies and directions of training. From the questionnaires from students majoring in landscape architecture, we were able to compare and analyze the satisfaction level of students on career education(education plans), textbooks, governmental career policies and career selection.

This study is to make suggestion for developing textbook systematically by analyzing biological contents and organization in science textbooks which are important instructional media to accomplish objectives of the 6th middle school science curriculum. The inclusiveness degree of the 6th science educational objectives reflected in the textbooks was analyzed by Klopfer's and the Korean Educational Department's objectives taxonomy. And the biological contents and the organization of the science textbook were analyzed by learner, subject matter, and society dimensions which are selecting criteria for curriculum objectives suggested in Tyler's curriculum model. The analyzed results are as follows: 1. The inclusiveness degree of the educational objectives was very low. 2. Regarding the dimension of learner, the concepts of formal operational cognitive level were much increased as grade becomes higher. And the degree of learner's interests reflected on the learning topics and domains was very low. 3. Regarding the dimension of subject matter, the concept-centered learning was increased, in relation to inquiry learning as grade becomes higher. The analyzed results of inquiry subskills showed that observation, classification, and recording skills in 1st grade, observation and operation skills in 2nd grade, and interpreting data skills in 3rd grade were centered. As the problems and processes were presented, so most of inquiry activities had low openness scale. The learning contexts were organized into discipline-centered in relation to real life. 4. Regarding society dimension, the learning topics of environments and health were much presented. but those of biotechnology and career were presented scarcely. And most learning topics related society dimension were organized in textbooks of the 2nd and 3rd grade. These suggested that to accomplish curriculum objectives effectively. the inclusiveness degree of educational objectives is to increase and, the contents and organization of textbook were constructed harmoniously in aspects of learner, subject matter and society dimensions.

Developing Mathematical Thinking has been continually emphasized in the Korean curriculum and this emphasis has demonstrated its impact on math textbooks and classes in South Korean schools. This study intends to discover how the Developmental Mechanism of Mathematical Thinking should be reflected through School Mathematics regardless of subfields of Mathematics or its levels. Finally, this study concluded that the Developmental Mechanism of Mathematical Thinking is being reflected on School Mathematics. However, more research in certain areas needs to be done. Through analyzing textbooks, it is certain that the Developmental Mechanism of Mathematical Thinking is being reflected on School Mathematics. Moreover, it appears that students are able to develop new concepts using Developmental Mechanism of Mathematical Thinking. Mathematical Thinking is a subject that many scholars and mathematicians have taken an interest in. Especially with the math curriculum in Korea, designing and implementing classes that would help students develop their mathematical thinking are increasingly being emphasized. This study defines what mathematical development mechanism is, and based on this definition, it further analyzes the math textbook of the revised 2007 curriculum. As a result, textbook developers and math teachers should examine and analyze the concepts that learners need to acquire and how they develop. Further, this study not only presents the concepts students are expected to acquire, but also looks at the flow in which concepts have been introduced to students. It concludes that activities that can help students have an idea of what they are going to learn in the future should be provided during class time.

In this study, 3D-image based course material has been suggested as a potential pedagogical tool for laboratory courses for aviational maintenance in vocational high schools. With a special focus on assembly/disassembly of the combustion chamber, 3D contents described here are created by Soildworks 2014 based on the textbook widely used in aviational high schools. By analyzing several textbooks currently adopted at various schools, we have clearly shown that the current text-based teaching method is far from being effective regarding providing adequate learning environment for high school students who study aviational maintenance. From the analysis of the conventional textbooks, it is seen that it is urgent that we should come up with more effective and efficient way of teaching methods for these topics at vocational high schools. Using Solidworks, we have developed very vivid 3D image-based course material for topics related to a combustion chamber in the airplane. Newly developed 3D material is seen to clearly show step by step procedures of assembly and disassembly of the combustion chamber which has crucial importance in the aviational laboratory courses. Especially the transparent feature in Solidworks could make it possible to observe the parts covered by outer casing, which can not be seen even in any laboratory class with real objects. 3D animated views could provided unprecedented learning environment for students to acquire core knowledge with ease for the maintenance of a combustion chamber. In order to provide easy access for students to this 3D-based course material, the exclusive viewer is also developed using MS office powerpoint 2007. An example of a learning plan using 3d course material is suggested as well.

The purpose of this research is to develop a Home Economics education curriculum that can promote citizenship through critical literacy. To this end, the 'housing' area in the 2015 revised curriculum of home economics and textbooks were analyzed from a critical literacy perspective. Using Laster(1986)'s critical science curriculum development course and "A Teacher's guideFamily, Food and Society"(Staaland & Storm, 1996), a 'Citizenship raising curriculum of home economics education in the housing area.' was developed. The results of this research are as follows. First, when the the curriculum was examined, the teaching objectives of the overall subject, or the achievement criteria, learning elements, and evluative methods of the housing area consisted of practical problem solving curriculum that can include critical literacy content. In addition, as a result of analyzing the text of the three textbooks' housing areas, it was found that most of them were described as adapting to and coping with the current culture, and few problems or social issues were mentioned that could lead to critical literacy. Second, the housing area curriculum for critical literacy learning was developed, with a total of 13 plan of 7 modules including continuous interests, valued ends, learning contents, and 26 learning materials including reading materials, and video materials. Based on the findings, the next curriculum and textbook should address social issues related to critical literacy and various classes of housing, and teachers' communities and training should be operated to support teachers who can be examplary for practical reasoning and critical thinking.

In this study, we investigated pre-service science teachers' NOS-PCK by analyzing their NOS lesson planning and demonstration. Four pre-service science teachers participated in the study. They planned and demonstrated NOS lessons in the context of 'Science Inquiry Experiment' developed under the 2015 Revised National Curriculum. Their lessons were observed. All of the teaching-learning materials were collected, and semi-structured interviews were also conducted. The analyses of the result revealed that pre-service teachers mainly referred to the curriculum and textbooks when selecting the NOS learning objectives. However, they felt difficulty because the curriculum and textbooks did not clearly present the NOS to be dealt. Although all of them took explicit approaches, there were not many open and divergent reflective approaches. In addition, they expected that high school students would consider scientific knowledge absolute and would have negative perceptions of NOS lessons. They rarely assessed students' NOS learning, and were reluctant to assess. Finally, most of them had a negative perception that learning NOS is not necessary for all students. On the bases of the results, educational implications for improving the expertise of pre-service science teachers in NOS lessons were discussed.

In this study, we propose a way to improve science teacher expertise through infographics creation teacher training program by analyzing the infographics types focusing on the Earth Science subject of the 2015 revised curriculum, and inspecting the teachers' utilization of graphic tools. The data visualization characteristics of Earth Science textbooks were analyzed, the execution results of the infographics creation teacher training program were presented, and a survey on science teachers' change in perception and competency of infographics. As a result of the Earth Science textbook analysis, diagram-type, map-type, and comparative analysis-type infographics were frequently used, and were mainly presented as text-assisted-type infographics. The infographics creation teacher training program was conducted five times for 112 science teachers to create the complete, text-assisted, incomplete, and gradient-type infographics. Incomplete infographics for development of evaluation questions were most needed. Although many science teachers recognize the importance of infographics, they lacked the competency to create high-quality infographics because there were no training opportunities for infographics creation. After completing the training, 74.1% of teachers felt that the quality of developments of supplementary textbooks and evaluation questions had improved, and answered that it was helpful in re-educating knowledge and improving teaching-learning methods. Based on the research results, ways to improve science teacher expertise through infographics creation teacher training program were suggested.

The purpose of this paper was analyzing the contents of life science area in elementary science textbooks according to Korean science curricula change to get suggestions for the advancement of science curriculum. The framework of content analysis was developed by revising TIMSS 2015 life science evaluation framework. The results of this research were as follows: 'The differences of living things and non-living things appearing in the first grade mostly were not included in the 1st, the 6th and the 2009 revised curricula. Contents emphasizing rural life were appeared from 'Teaching themes period' to the 2nd curriculum period, disappeared from the 3rd curriculum period until the 2009 revised curriculum. Contagious disease was emphasized in all elementary grades in the 1st curriculum period, which reflected a social phenomena emphasizing health and hygiene after the Korean War. Mostly fungus was included until the 7th curriculum period and bacteria and virus were added from the 2007 revised curriculum period. The way of improving health was emphasized continuously.' The differences of living things and non-living things should be included in elementary science curriculum for the correct 'life' concept formation of elementary students. 'Strategies for helping the living of descendants' and 'the heredity of animal and plant' which were appeared in the lower grades, should be included at the higher grades with greater depth. The incoming elementary science textbooks also need to include science contents about evolution in greater depth, along with human health.
