On March 2011, an annual salary plan was applied to new faculty members in National Colleges and Universities. In 2015, all tenured faculty members will receive salaries based on annual performance evaluations. The efforts and accomplishments of faculty are normally assessed according to a standard formula of 40% teaching, 40% research and 20% service. In almost all colleges and universities, student course evaluations may be considered as the only measure of the perceived quality of the courses offered by the faculty member. The mandatory course evaluations are becoming prevalent in Korea. The results of course evaluations do not reflect the fairness and the appropriateness of the quality of the course taught by the faculty member and should not be considered under the teaching evaluation criteria.

Course evaluation serves as helpful information to improve the quality of college education and improve lectures. This study derived the factors through preceding research and FGI to explore the factors that constitute course evaluation and identified the relative importance and priority of the factors through the Analytic Hierarchy Process (AHP). For this, it derived five factors and 15 evaluation items as follows. To secure expertise and fairness in the factor development of course evaluation, the researcher conducted a questionnaire surveying students and teachers and collected a total of 20 valid data. The weight of each evaluation item was calculated based on the data that had been verified for consistency. The analysis concluded that students rated class content, class method, class operation, class evaluation, and class plan as the critical factors in the order of importance, while teachers evaluated class content, class operation, class method, class evaluation, and class plan as important, in that order. Based on the results of this study, I hope that various analyses and studies will be conducted to improve the efficiency and reliability of course evaluation for the quality management of college education.

본 논문은 강의 시 외국인에게 번역된 강의 내용을 보다 효율 적으로 전달하기 위한 자막 전송 강의 시스템에 대하여 기술한다. 기존 자막 서비스는 화면 하단에 자막을 두는 방법으로 사용되고 있다. 하지만 이러한 방법을 사용할 경우 다국어 자막 안내는 불가능하다. 또한 자막이 필요 없는 청중에게는 불필요한 서비스가 된다. 따라서 본 논문에서는 블루투스 Low Energy 비콘을 사용하여 효율적인 실시간 자막 전송 방식을 제안한다. 여러 언어로 실시간 번역된 자막을 비콘을 통하여 브로드 캐스팅 하여 번역 서비스가 필요한 청중은 스마트폰을 이용하여 원하는 언어의 자막만 수신 할 수 있다.

2015 개정 교육과정의 적용에 따라 학교 현장에 새로운 요구와 문제 상황이 예상되며, 이에 따라 정보 컴퓨터 교사양성과정도 적절하게 변화될 필요가 있다. 본 연구에서는 예비 정보교사들이 교육현장의 요구와 문제 상황에 대해 직접 고민하고 해결방법을 구안해보도록 하는 방법으로 캡스톤 디자인을 적용하였다. 이를 위해 현재 운영 중인 캡스톤 디자인 강의의 동향을 살펴보고 교과교육영역의 과목과 다루어야 할 정보교사의 자격기준을 살펴보았으며, 이를 바탕으로 캡스톤 디자인 정보교과 교재연구 강의를 설계하였다. 후속 연구로 설계한 강의를 예비 정보교사들에게 적용하고, 이에 대한 효과성을 검토할 것이다.

동영상 강의는 시간이나 장소 등에 크게 구애받지 않고 인터넷을 통하여 쉽게 이용할 수 있는 간편한 학습방법중의 하나이다. 그러나 학습자의 학습자세와 태도에 따라 학습효과는 매우 다를 수 있는 문제점을 가지고 있다. 본 논문에서는 입력영상으로부터 학습자의 얼굴정보를 입력받아 주기적으로 탐색하여 학습자의 강의에 대한 집중도와 충실도를 평가하는 시스템을 제안하고자 하였다. 먼저 입력영상의 분할된 중심영역으로부터 학습자의 얼굴을 포함하는 신체정보를 입력받아 사용하였으며, 빠르고 효율적인 얼굴영역의 추출을 위하여 피부색상(skin-color)정보와 얼굴의 지역적 특성을 이용하는 방법을 사용하였다. 또한 주기적으로 입력되는 영상의 빠른 얼굴추적을 위하여 설정된 영역들로부터 구성되는 블록들의 위치와 구성정보를 이용한 블록탐색 기법을 사용하였다.

원격 교육에서 실습 관련 교과목에 대한 이해 접근 방법은 시각적인 학습을 통해 이루어지는 것이 보다 효율적이고 능률적이다. 그러나 사이버 강의에서 실습관련 교과목 피드백 시 직면하게 되는 가장 대표적인 문제점은 설명하기 어렵거나 이해하기 어려운 상황에 대해 학습자는 문자로서만 교수자에게 전달해야 하고, 교수자는 그 상황을 유추해서 응답 해주어야 한다는 사실이다. 따라서 학습 매체로써 탄력적인 수업이 이루어지기 위해서는 다양한 형태의 피드백으로 강의 컨텐츠를 개발하고 이를 적용하여, 교수자가 학습자의 실습 내용을 실시간으로 볼 수 있는 프로그램과 시스템의 개발이 필요하다. 본 연구에서는 여기에 초점을 맞추어 실습과목의 효과적인 피드백을 구현할 수 있는 방법을 제안하고 검증하였다.

Since educating digital convergence is to unite various sciences and technologies with computer as the central figure, it has different range and methods of education. Therefore, it has problems with recommending limited conceptual information because of difficulties to standardize education plan and teaching strategies. In this paper, I propose education plan and teaching strategy system by using Spearman correlation coefficients. This system is to find a solution against disadvantage of recommending limited conceptual information by ranking relations of teaching strategies from the information based on the demand of industrial and academic fields, and then provides lists of teaching strategy information suitable for user's atmosphere and characteristics. Performance test is to compare effects of precision and recall with existing service systems. The test shows 90.4% of precision and 77.6% of recall.

We introduce an introductory engineering education course for engineering majors and non-engineering majors. This course does not require any previous knowledge and experience on engineering. It requires strong curiosities and imaginations on current and future society we live in, where technology is inseparable ingredient. Course encourages attendees to explore fundamental issues of engineering: what is proper technology and what are proper ways of exercising engineering, issues dealt in soft engineering. Since course topics cover many aspects of technology, traditional learning methods fail to be successful and efficient. Various efficient learning methods have been proposed and implemented. We utilize various interactive tangible media, which include simulated thought experiments and physical media experiences. About twenty (20) episodes in short film format are produced based on scenario written according to related issues selected. Physical media like interactive robots are introduced for attendees' stimulated experiences. We summarize our exciting experiments on interactive teaching experiences at Pusan National University which include on/off-line interactions, assignments, projects, and evaluations.

This study has been conducted to investigate the awareness of questions for course evaluation with targets of 968 students in Department of Dental Hygiene at 6 colleges(universities) in Busan, Gyeongnam and Ulsan areas. The reliability, Cronbach' ${\alpha}$, of awareness of questions for course evaluation was .862, which was high. Data analysis was performed by using SPSS IBM. SPSS. Statistics. v. 19.0 program with the significance level of 0.05. As the results of this study, first, awareness score of questions for course evaluation was the average of 2.99, which was high. Second, the important factor of questions for course evaluation in entire grade was contents of class and teaching methods, and it was 59.3%, which was the highest. Third, the relevance between important factors of course evaluation and reliability of questions for course evaluation was the average of 3.06, which was higher than the validity of 2.97. Fourth, the correlation between reliability and validity of questions for course evaluation was 0.608, which showed a strong positive correlation.
