We have examined the perception of teachers and students in elementary schools toward the frontier science and analyzed corresponding contents in science textbooks in Korea and the U. S. in order to promote a good guidance for the frontier science education. We prepared separate questionnaires for teachers and children, respectively, and analyzed the responses obtained from 244 teachers and 1,000 students in five elementary schools. For the analysis of how to introduce the frontier science, we investigated textbooks such as Science, Society and Practical Arts of Korean elementary school, and an American science textbook published by Scott Foresman. This study revealed that teachers are well aware of the importance of the frontier science, however, they are inactive in conducting the subject in class rooms because of their insufficient scientific knowledge and poor environment for teaching. It has been found that children had strong interest in the frontier science, however, opportunities to learn the topic are not properly provided. The frontier science m the American science textbook turned out to be more systematically introduced than that in Korean ones.

Robots have been attracting students' interest recently. Therefore, they are a good way to motivate to study related subjects. However, there are difficulties in teaching general students because a wide background is required to understand the fundamentals of robotics. In order to teach robotics fundamentals to beginners in a short period, an effective experimental class, including several phased experiments, is proposed in this paper. A portable two-DOF robot arm system with servo motors was developed for experiments, and the operation method based on kinematics was introduced for its operation. The effectiveness of the class was investigated by using a questionnaire after carrying it out in a university class for junior students.

합성곱(convolution)은 인공지능(artificial intelligence)에서 컴퓨터 비전(computer vision), 심층학습(deep learning) 등의 분야를 이해하고 응용하려면 알아야 하는 중요한 수학적 연산이다. 그러나 현재의 공학수학 교과과정의 합성곱 내용은 독립적인 주제가 아니라 단편적으로 다루어지고 있어서 그 의미를 충분히 전달하지 못하고 있다. 이에 본 논문에서는 공학수학에서 인공지능 교육과 연계할 수 있도록 개발한 합성곱 교수·학습 자료를 제시한다. 먼저 기존 공학과 인공지능 기술의 통합적 관점에서 합성곱에 대한 배경지식과 응용 사례를 정리하고, 코딩을 이용한 교육이 가능하도록 파이썬(Python)/SageMath 코드를 개발하여 제공한다. 또한 합성곱 지식이 인공지능에서 어떻게 활용되는지 보여주는 구체적인 예시로, 이미지 분류에 사용되는 합성곱신경망(Convolutional Neural Network, CNN)을 개발된 코드와 함께 제공한다. 본 교수·학습자료는 합성곱 개념을 쉽고 효과적으로 교육할 수 있도록 공학수학의 보충 자료로 활용가능하며, 학습자는 코딩을 통해 합성곱을 배우고 본인의 전공과 관련된 인공지능 기술을 학습하는 데 이를 이용할 수 있다.

Through the criticism and evaluation of different classes teaching the same lesson topic, this study compared the viewpoints by two ways between two groups including pre-service and experienced teachers. Through free-style criticism, this study analyzed the differences between pre-service and experienced teachers' areas of attention. Through criteria-based analysis, the study analyzed the judgement of each area and the criteria of each judgement. The results of the study found that pre-service teachers criticised more limited areas, but somewhat more positive than their experienced teacher counterparts. Also, pre-service teachers did not observe thoroughly whether or not the teacher was well-informed of the science content, the sequence of curriculum, and whether or not meaningful interaction had occurred. As well as, pre-service teachers were not actually feel importance of student-oriented lessons, and they could not look room and materials are useful to students on students' sides. Additionally, pre-service teachers thought highly of lessons which were connected to other subjects rather than connected to daily life. Therefore, to notice diverse areas in the class, pre-service teachers need to criticise lessons using a diverse criterion. Also, pre-service teachers realized simple questions and that mechanical group activities are not always effective and that they need to think how to improve meaningful interaction. Moreover, they have to perceive that an inquiry-oriented student-lead approach is very important. Lastly, pre-service teachers have to closely consider the room efficiency and materials available to the students, and they must internalize that science class has to be connected with daily life.

The purpose of this study is to offer youth with the basic materials for developing nutrition education programs and to help domestic science teachers in schools implement effective dietary education by examining their awareness of food additives. In the source of acquiring knowledges on food additives, the results were through mass media, technology and home economics teachers, and family members in order. The majority of students thought that they don't need the education about food additives. As effective teaching methods, they first selected the use of visual media, followed by experimental cooking classes, field trip, and inquiry lessons using processed foods. As a result of analyzing the education on food additives in accordance with demographic factors, more number of female students, compared to male students depicted the need for education on food additives. Further, the lower the cost students spend on purchasing processed foods per day, the higher the necessity of the education they indicate. The necessity of education content on food additives showed significant difference depending on the cost of buying processed foods, and the degree of interest and help real-life according to gender indicated significant differences. The satisfaction with education on food additives, which was implemented in home economics education revealed significant differences according to gender. This study aims to provide the basic data for the development and research of educational programs regarding good eating habits among the general youth. However, there are limitations to the presentation of the practical training program. For this reason, based on the results of this study, further studies should follow this study in order to develop and study educational programs related to food additives for teaching and learning purposes.

Information technology will inevitably and profoundly alter every aspect of university life. New information technologies are creating new patterns in the research and teaching, with networks enhancing information sharing and data transmission. The revolution in information technology requires that universities integrate information technology with their traditional missions of teaching, research, and public service. Enhanced mode of information access and changing information-seeking behaviors suggest the need for new library services. New technologies have opened up many new services options for libraries. The nature of and potential for new information services suggest that libraries should become better connected with other campus units. Some of these issues will no doubt be addressed by the a n.0, pplication of new technologies and by building campus information infrastructure. An important element of the needed change for enhancing the library information services is the integration of the libraries and computing centers. Libraries and computing centers deal with the same commodity-information and delivering information. For the sake of scholarship and research, the two must devise an integrated a n.0, pproach to delivering the common commodity. Computing centers have special skills in system development and telecommunications. Libraries have good human interface skills and skills for organizing knowledge. Together they could be a particularly productive team. Noting this, some universities have created new information service units which unify the present-day computing, library and telecommunication functions. Existing models range from true merging to situations where some cooperative activities are being conducted. The purpose of this study is to suggest the direction in developing of information services in academic libraries by examining the changing information environment and trends of integrating libraries and computing centers. This paper inquires into the changing information environment, the impact of imformation technology on universities and libraries, some casses of integration of academic libraries and computing centers, and effects of integration of two and suggests the developing direction of information services in academic libraries.
