The purpose of this study is to analyze the characteristics of STEAM-based research and education (STEAM R&E) projects for secondary school students. From 2012 to 2015, 400 STEAM based Research and Education (R&E) projects have been conducted, and they were selected for this study. The major findings are as follows: First, Science (S) and Mathematics (M) were identified at a high rate in STEAM-based Research and Education (R&E) projects, and Art (A) was identified with the lowest rate. Second, 'STEM' type was identified at the highest rate among STEAM-integrated types. And there were not any trends as the years go by, but STEAM-integrated types, where three or more STEAM elements were integrated, were identified at an increasing rate. It means that students use STEAM elements in various ways gradually. Accordingly, the results suggest: The information material that guide how to utilize STEAM factors diversely should be provided for project participants to improve their creativity and problem-solving abilities.

Teachers and students tend to perceive mathematics irrelevant with character education. Since there has been no teaching of cross-curriculum characters education in mathematics classrooms, this research was to look for the possibility of teaching the character education in mathematics. Through the pilot study, trying to rebuild character factors based on Moon, et al,(2011), the researcher applied them to developing 8 lesson plans and carried them to 12th graders of the high school in March and April, 2014 using pre and post tests. Based on statistically significant difference with the level of p<.05, in "relation with me", for 'appointment' in the pretest, the students of natural science(SNS) exceeded, but in the posttest the students of humanities(SH) exceeded. In "relation with the other", in the posttest, for 'forgiveness' and 'responsibility' SNS, but for 'ownership' SH exceeded. In 'relation with a group' in the pretest for 'community spirit' SNS, and in the posttest SH exceeded. In the pretest in this study SNS naturally perceived the value of character education in math classes since they were closer to mathematics but after the experience through character education with cross-curriculum factors, SH perceived its importance expecially 'appointment', 'ownership', and 'community spirit' more than SNS so that we could predict the possibility of teaching cross-curriculum character factors in mathematics even after they had preconception as a high school student.

This study is to develop a competence model for school principals that provides effective career and vocational education (CVE) at middle schools. This model can be used as an indicator for identifying the expertise levels of principals in CVE and to help them develop the necessary skills. Research methods included literature review, basic research, the Delphi technique, analytic hierarchy process (AHP), and surveying. The results were as follows. The competence model for CVE for middle school principals consisted of three competence groups, nine competence elements, and 67-item behavior indicators. First, the three competence groups included the competence to build a school system for CVE, the competence to support CVE at school, and the competence to create a school environment for CVE. Competence to support CVE at school turned out to be most important in the AHP analysis. Second, competence elements included goal management, performance management, the creation of educational culture, support for educational activities, support for school curriculum, support for students, human resources management, resource management and community management. According to the AHP analysis, support for school curriculum was the most significant among the nine competence elements. Third, the behavior indicators were identified items in three areas: 18 items for individual propensity, 18 items for knowledge, and 31 items for performance.

There are several studies in order to learn about programming language. This paper develops a peer agent system based on teaching and learning strategies in order to improve problem-solving ability. Problem-solving ability involves three components - content understanding, domain-dependent problem-solving strategies, and self-regulation. This paper shows the teaching and learning strategies about components of problem-solving for learning to program and the peer agent system uses the teaching and learning strategies. This study intents to analyze the educational effects of the peer agent system. The results show that the system has superior effects on problem-solving ability compared to traditional programming courses or pair programming courses. It means that the peer agent system is the effective educational system in improving student's problem-solving ability.

This study analyzed what STEAM elements, except mathematical content, are contained in 2009 revised elementary school 5th and 6th grade group mathematics textbooks. STEAM elements in the textbooks were examined by grade and by content area in the elementary school mathematics curriculum. The results were as follows. First, the number of STEAM elements in mathematics 5-1, 5-2, 6-1, 6-2 are 151(18.4%), 212(25.9%), 211(25.7%), 246(30.0%), respectively. The 6th Grade than in 5th Grade can be seen a few plenty. Second, the number of STEAM elements are different depending on the type of STEAM. The number of arts element is 617(75.2%) and this elements are seen the most. The number of representative art and cultural art is 445(54.3%) and 172(20.9%), respectively. The number of technology-engineering and science is 158(19.2%) and 45(5.5%), respectively. We need to developed to promote use of science element in next mathematics curriculum.

The national competency standards (NCS) is a systematize and standardize for skills required to perform their job. The NCS has developed a learning module with materialization and standardize by competence unit element, which is the unit of specific job competency. The existing curriculum is material to gab analysis for use in education training with competence unit element. The existing gab analysis has evaluated subjectively by experts. The gab analysis by experts bring up a subject subjective decision, accuracy lack, temporal and spatial inefficiency by psychological factor. This paper is proposed automated evaluation model for problem resolve of subjective evaluation. This paper use index term extraction, term frequency-inverse document frequency for feature value extraction, cosine similarity algorithm for gab analysis between existing curriculum and competence unit element. This paper was presented similarity mapping table between existing curriculum and competence unit element. The evaluation model in this paper should be complemented by an improved algorithm from the structural characteristics and speed.

In this research, Problem Solving and Programming - the chapter common among four different types of middle school informatics textbooks based on the national curriculum revised in 2015 - was analyzed to measure its effects on cultivating students' curiosities. Romey's analysis was applied to these textbooks on four analytic elements - texts, data, activities, and evaluation. The results showed that each type of textbook showed a differing degree of encouraging students' inquisitive tendencies on each analytic element; two out of four textbooks were well developed for texts, three for data, three for activities, and all four for evaluation. In terms of Romey's index points, two textbooks had low indexes of texts, such as 0.185 and 0.413. Data indices were extremely low in one textbook at 0.147. Three of four textbooks exhibited high indices of activities at 0.969, 0.608 and 0.627. Evaluation indices were high in all four textbooks at 1.333, 1.268, 1.274, and 0.764. These revised textbooks overall showed higher metrics than the previously designed textbooks with regards to promoting students' inquisitive nature.

In recent years, astronomy has been snowballing: including Higgs particle discovery, black hole imaging, extraterrestrial exploration, and deep space observation. Students are also largely interested in astronomy. The purpose of this study is to discover what needs to be improved in the current astronomy curriculum in light of recent scientists' researches and discoveries. We collected keywords from all papers published from 2011 to 2020 in four selected journals-ApJ, ApJL, A&A, and MNRAS- by R package to examine research trends. The curriculum contents were extracted by synthesizing the in-service teachers' coding results in the 2015 revised curriculum document of six subjects (Science, Integrated Science, Earth Science I, Earth Science II, Physics II, Convergence Science). The research results are as follows: first, keywords that appear steadily in astronomy are 'galaxies: formation, galaxy: active, star: formation, accretion, method: numerical.' Second, astronomy curriculum includes all areas except the 'High Energy Astrophysical Phenomena' area within the common science curriculum learned by all students. Third, it is necessary to review the placement of content elements by subject and grade and to consider introducing new concepts based on astronomy research keywords. This is an exploratory study to compare curriculum and the field of scientific research that forms the basis of the subject. We expect to provide implications for a future revision of the astronomy curriculum as a primary ground investigation.

The purpose of this study is to examine the educational contents of home economics textbooks that solely focus on forming adolescent empowerment. For this, an in-depth content analysis was conducted on the home economics textbooks in Korea and the U.S. The main results of this study are summarized as follows: First, the 23 content elements, which are designed to build adolescent empowerment, were ascertained: nine intrapersonal empowerment elements such as the self-identity, nine interpersonal empowerment elements such as the communication, and five social empowerment elements such as the leadership. Second, based on the content elements selected from above, the textbooks in Korea were observed to deal with 58% of the 23 content elements, while those in the U.S. discussed 90% of the 23 content elements. Korean textbooks primarily focused on helping students understand major concepts, whereas the U.S. textbooks focused primarily on helping students make connections between major concepts and their life. Lastly, both countries put the least amount of weight on social empowerment content elements(Korea: 37%, U.S.: 70%).
