This study constructed a structural model and examined the fit and significance of the model to identify the influencing factors on the organizational commitment of ROTC cadets. The subjects of this study were 209 male students in grades 3 and 4 ROTC cadets of eight universities located in D, P, and G cities. Data were collected from April 13 to May 29, 2018. The data collected were analyzed by SPSS / WIN 20.0 and AMOS 21.0 programs. A positive correlation was observed between the ROTC instructor's leadership, self-efficacy, job satisfaction, and organizational commitment. Six of the six pathways of the hypothetical structural model were statistically significant. The hypothetical model showed a good fit for the data. The model fit indices were ${\chi}^2/df=1.51$, GFI=.98, AGFI=.90, NFI=0.98, NFI=.97, RMR=.02, RMSEA=.05, and TLI=.98. The ROTC Instructor's leadership and self-efficacy had direct and indirect effects on the organizational commitment. Job satisfaction had the strongest direct influence on organizational commitment. This model explained 73% of the variance in organizational commitment. Therefore, it is necessary to develop an effective education and intervention program that can enhance the ROTC instructor's leadership, self-efficacy, and job satisfaction to increase the organizational commitment of the ROTC cadets.

Peer assessment refers to having students, rather than the instructor, make assessments of one another's work. Peer assessment is often used as a tool to train writing skills or a tool to apply or extend learning in higher education. Park(2016) recently proposed a system which utilizes peer assessment as a part of preparatory activity for college courses. Before weekly class, students studied given material on their own, wrote a one page essay on a given question based on their reading, and assessed the essays of other students. In this study, the system was implemented in undergraduate courses at S University over 2 semesters and the results were analyzed. The reliability of weekly scores given by students was not very high, but the correlation was high between the cumulative scores given by students across weeks and the scores of the end of the term paper assessed by the instructor. Based on these findings, the possibility of utilizing the results of the peer assessments as part of the final grades was discussed.

As recent developing computing environments, service is provided without time or place's limitation, and it is constituted dynamically. Above all, in terms of education supporting system, there is need to conceive user's information and provide optimal service as to right with applying context awareness under Ubiquitous computing environment. It should have groundwork based on user location and time. It is requires service providing based on user location under the condition of class to offer appropriate service with the context. In addition, context information providing technology is needed to offer right education support service in the class, where are different context information. Hence, in this research it is suggested education supporting system to provide context-based for instructor. The framework of this system has a foundation within previous work about Multi-agent based Distributed Framework. To examine implementation of context-based education supporting system in Ubiquitous computing environments suggested by this report, arranging system can fit information relates to instructor's location for service applying in the class.

Human dance is difficult to learn since there is no effective way to imitate an expert's motion, a sequence of complicated body movements, without taking an actual class. In this paper, we propose a dance learning system using human depth information. In the proposed system, a set of example motions are captured from various expert dancers through a marker-free motion capture and archived into a motion database server for online dance lessons. Given the end-user devices such as tablet and kiosk PCs, a student can learn a desired motion selected from the database and send one's own motion to an instructor for online feedback. During this learning process, our system provides a posture-based motion search and multi-mode views to support the efficient exchange of motion data between the student and instructor under a networked environment. The experimental results demonstrate that our system is capable to improve the student's dance skills over a given period of time.

We arranged and classified rearing patterns of gifted children's parents in order to find out mothers' roles for their gifted children. We developed a frame of parents' role to analyze the rearing cases of nine mothers whose children currently attend the Korea Science Gifted Academy. We surveyed and conducted semi-structured interviews with nine mothers to collecting qualitative data and were able to find out their roles that were classified into 4 distinctive roles: Instructor, Supporter, Dialogist and Moral Discipliner. Findings indicated that there was no significant difference between the roles found from parents' interview and the ones found from literature review. However, it is noticed that Korean mothers not only played a role for connecting their children's human networks but also did the role for controling the natural process of learning Korean characters and words with siblings as well as parents before school age.

With the development of information and communication technology and the increasing use of smart devices, universities are using an electronic attendance-absence management system using smart devices to facilitate efficient attendance management. Currently, the electronic attendance-absence management system has the disadvantage of causing an error in attendance when the Wi-Fi connection is not well established because the student's smartphone independently conducts electronic attendance, and it is difficult to manage attendance because the real-time push message transmission function is excluded. In this paper, we propose an electronic attendance-absence management system to prevent irregular attendance, provide real-time attendance results, and solve delays in attendance processing due to Wi-Fi connection problems. The proposed system can prevent delays in attendance processing as a result of irregular attendance because the instructor's smartphone processes proposed system using the Bluetooth communication function of the instructor's smartphone and the students' smartphone. In addition, it has the advantage of being able to notice management result in real time with the push message server.

In order to overcome the limitations of the instructor-centered lecture-style teaching method, recently, flipped learning, a learner-centered teaching method, has been widely introduced. However, despite the many advantages of flipped learning, there is a problem that students cannot solve questions that arise during prior learning in real time. Therefore, in order to solve this problem, we developed DBbot, an assistant chatbot for database design course managed in the flipped learning method. The DBBot is composed of a chatbot app for learners and a chatbot management app for instructors. Also, it's implemented so that questions that instructors can anticipate in advance, such as questions related to class operation and every semester repeated questions related to learning content, can be answered using Google's DialogFlow. It's implemented so that questions that the instructor cannot predict in advance, such as questions related to team projects, can be answered using the question/answer DB and the BM25 algorithm, which is a similarity comparison algorithm.

This study aims to investigate how to apply the theory of constructivism to CADD education. To maximize educational effect in the educational process, evaluation, media, interactions between instructor and learners, existing CADD education has some limitations and needs new methodology. Constructivism can be said to be a learner-oriented theory in that it emphasizes on the process of understanding in each individual. It can contribute in educational practice to elicit each learner's motivation and to develope their creativity. This paper tried to investigate how to apply constructivism to architectural designing and find the most suitable CAAD education methodology related to design studio.

As interest in software education has increased, discussions on teaching, learning, and evaluation method it have also been active. One of the problems of software education teaching method is that the instructor cannot grasp the content of coding in progress in the learner's computer in real time, and therefore, instructors are limited in providing feedback to learners in a timely manner. To overcome this problem, in this study, we developed a software education support system that grasps the real-time learner coding situation under block-based programming environment by applying a learning analysis technique and delivers it to the instructor, and visualizes the data collected during learning through the Hadoop system. The system includes a presentation layer to which teachers and learners access, a business layer to analyze and structure code, and a DB layer to store class information, account information, and learning information. The instructor can set the content to be learned in advance in the software education support system, and compare and analyze the learner's achievement through the computational thinking components rubric, based on the data comparing the stored code with the students' code.
