The purpose of this study is to develop STEAM program for gifted education by combining educational contents of humanities, arts, engineering, technology, and design into various subjects, focusing on mathematics-science curriculum of elementary school. The achievement standards and curriculum contents of elementary mathematics-science curriculum were analyzed while considering 2015 revised national curriculum. And then, a 16 class-hour convergence education program consisting of 3-hour block time was developed by applying the STEAM model with 4 steps. The validity of the program developed through this process was verified, and four educational experts evaluate whether the program can be applied to the elementary school. Based on the evaluation results, the convergence education program was finalized. As a result of implementing the gifted education program for mathematics-science, students achieved the objectives and values of convergence education such as creative design, self-directed participation, cooperative learning, and interest in class activities (game, making). If this convergence education program is applied to regular class, creative experiential class, or class for gifted children, students can promote their scientific creativity, artistic sensitivity, design sence, and so on.

The purpose of this study was to analyze the research trends of elementary mathematics education in terms of topics, methods, subjects, mathematics content strands, and mathematical competencies. For this purpose, a total of 596 papers published in eight domestic journals during the recent seven years were analyzed. The results of this study showed that the popular research topics included learners' perspectives and abilities, analysis of curriculum and textbooks, and instruction and teaching methods, whereas studies on assessment and technology or manipulative materials did not get much attention. The results also showed that qualitative research methodology was used a lot with focus on students. The mathematics content strand which was most frequently studied was number and operations, and problem solving was most popular among the mathematical competencies. On the basis of these results, this paper includes several implications for the future research direction in elementary mathematics education.

This study analyzes the effect of CAE class using PBL on professional knowledge acquisition and competency enhancement. The PBL class was applied to 3rd grade students of Dong-Eui University's Department of Automotive Engineering, and a one-year course, and a survey was conducted on satisfaction and effectiveness in the first and second semesters, respectively. With a significant difference in the survey for each semester, satisfaction in the second semester was found to be high, and satisfaction with non-face-to-face information exchange and team activities was high. In addition, it was evaluated to have a positive effect on the improvement of individual competency such as knowledge of subject, command-led learning, problem-solving ability, and communication. This study has educational implications in that it can be used as a quantitative indicator for class improvement and can be used as basic data for course operation.

This study aimed to derive pedagogical implications by comparing and analyzing how the concept of pi is taught in 10 different elementary mathematics textbooks, which are scheduled to be applied from 2023. We developed a textbook analysis framework by previous studies on the concept of pi and the teaching of pi, and analyzed in terms of three instructional elements (i.e. inferring conceptsof pi, understanding properties of pi, and applying relationships). We derived the need to emphasize various contexts for estimation of pi, presentation of problem situations that provide motivation to actually measure diameters and circumferences, providing an opportunity to explore the properties of measurement, and an experience the flexibility of selecting an approximate value of pi. Based on the above conclusions and pedagogical implications through the research results., we suggested ways to teach the concept of pi in elementary mathematics and improvement points for developing textbooks focusing on the context of introduction of pi and the use of technological tools.

At the K University level in the first semester of the 2022, regarding the courses opened as intensive completion-type major knowledge linking, under the name of 'Collage', 47 students were formed along with students majoring in electronic engineering (21 students) and included 26 students from 14 other majors. It was convergencly conducted as a 5-week completion-type independent course, and the results of responses to 10 items on the 5-point Likert scale questionnaire were summarized. The organized results were tested for four items (reliability, normality, correlation, average difference between 2 groups), and it was confirmed that there was a difference in learning satisfaction depending on the difficulty of the learning topic and the grade of the student. In addition, it was confirmed that more than 65% of the students responded with a positive evaluation of 'moderate' or higher in the five questionnaire items with high correlation.

This study investigated the improved teaching methods which can enhance the learning effects of students in engineering education and provide students with practical abilities of field works. As the results of applying student-oriented teaching methods to students who take the course of hydraulic and pneumatic control in the department of mechanical design engineering of Dongyang technical college, student-oriented teaching method Is more effective than professor-oriented teaching methods in the aspects of motivation of learning, cultivation of imagination and creativity, and ability of solving problems. In order to successfully execute student-oriented teaching method, integrated lecture of both theory and experimental practice has been carried out in the classroom equipped with experimental facilities, and after acquiring sufficient experience through experimental practices, students looked into theoretical backgrounds based on the experimental results during the process solving the subjects which a professor suggested. The subjects should be suggested with the contents for accomplishing the goal of learning, and it is very important for a professor to play the role of helping students solve the problems by themselves, which results in improving practical ability of field works. At the end of every class, a professor has students fill up the questionnaire about the level of learning achievement, questions, and teaching method, and applying the surveying results to the next class can bring out improving the extents of students' participation of classes and concerns about the course. Since the engineering education requires a practical ability of field works, imagination, and creativity in every course, it is desirable to introduce student-oriented teaching method rather than professor-oriented teaching method.

The advancement of artificial intelligence on a global scale is significantly transforming life. In the field of education, there is a strong emphasis on actively utilizing AI and fostering creatively integrated talents with diverse knowledge. In alignment with this trend, there is a paradigm shift in AI education across primary, middle, high school, as well as university and graduate education. Leading AI schools and specialized high schools are dedicated to enhancing students' AI capabilities, while universities integrate AI into software courses or establish new AI departments to nurture talent. In AI-integrated education graduate programs, national efforts are underway to educate instructors from various disciplines on applying AI technology to the curriculum. In this context, specialized high schools are also restructuring their departments to cultivate technological talent in AI, tailored to students' characteristics and career paths. While the current education focuses primarily on the fundamental concepts and technologies of AI, there is a need to address the aspect of developing practical problem-solving skills. Therefore, this research aims to compare and analyze essential educational courses in AI-leading schools, AI-integrated high schools, AI high schools, university AI departments, and AI-integrated education graduate programs. The goal is to propose the necessary educational courses for AI education in specialized high schools, with the expectation that a more advanced curriculum in AI education can be established in specialized high schools through this effort.
