한 가지 문제에 대한 다양한 풀이 방법을 탐색하는 것은 수학적 대상의 성질을 발명, 일반화하는 것 뿐만 아니라, 학생들의 지적인 유창성 및 유연성 계발, 수학에 대한 심미적 가치의 함양을 위한 의미 있는 교수학적 경험을 제공할 수 있을 것이다. 본 연구에서는 고등학교 '미분과 적분'에 제시된 사인의 덧셈정리에 대한 다양한 증명 방법을 제시하고, 이를 분석하여 수학교수학적으로 의미로운 시사점을 도출하였다. 이를 통해, 사인의 덧셈정리에 대한 새로운 증명 방법의 탐색, 사인의 덧셈정리의 수학교수학적 활용의 다양한 가능성을 모색할 수 있는 기초자료를 제공할 것이며, 제시된 증명 방법들은 '미분과 적분'의 지도에서 심화학습 자료로도 활용할 수 있을 것이다.

본 논문은 비전공자의 프로그래밍 수업에서 발생하는 오류들을 수집하고 오류 유형을 분석하여 초보 프로그래머의 오류 문제 해결을 쉽게 접근할 수 있도록 하고 교수자가 하는 피드백을 인공지능을 통해 자동화하는 시스템을 개발하는 기초 연구가 되는 것을 목표로 하였다. 결과로는 분석한 오류 유형에는 컴파일 타임에러가 가장 많이 발생하였고 그중에서도 구문에러(syntax error), 그중 missing 에러가 가장 많이 나타났다. 비전공자 학습자는 에러메시지를 이해하는 것을 가장 어려워하였고, 교수자의 피드백을 가장 절실하게 필요로 하였다. 좋은 오류 메시지는 초보자 프로그래머를 위한 프로그램 사용성에 큰 차이를 만들 수 있어 오류 메시지 내용을 단순화시킬 필요가 있으며, 학습자와 교수자의 상호작용을 효율적으로 이루어지게 할 필요가 있고, 인공지능을 통한 피드백을 자동화할 필요가 있음을 제언하였다. 향후 과제로는 오류 유형 중 자주 발생하는 구문에러부터 해결할 수 있는 인공지능을 이용한 자동 피드백 프로그램을 만들어 학습자와 실시간 상호작용하여 온라인에서 프로그래밍 수업이 가능한 학습시스템을 구현하고자 한다.

Educational robots have various potentialities to support programming learners because it is interesting enough to improve the learners' participation and motivation. Nonetheless, some researches assert that the use of educational robot does not necessarily lead to effective and successful learning. With respect to these serious problems, the researchers are emphasizing that it is needed to overcome the probable 'Novelty Effect' by means of considering specific features of the robot programming environment and the participants. We analyzed and found some features of robot programming teaching and learning environment and professional high school students through reviewing of the literatures, and then conducted delphi research to abstract motivational strategies and to develop their applying methods with the specific features. We developed a robot programming teaching and learning model for stimulating and maintaining professional high school student's motivation, which includes 5 factors and 21 strategies.

The purpose of this primitive experimental study was to find the effects of peer teaching on self-leadership, psychological capitals(hereafter, psycap) and learning satisfaction of nursing freshmen. The data measured before and after 12 times peer teaching for 30 minutes were analyzed with SPSS 21 for descriptive statistics, t-test, ANOVA and paired t-test. There were significant increases in academic satisfaction of low subjective school grades group, and in resilience of below average prefer discussion group before and after treatment. There were significant differences in self-leadership and psycap before and after treatment(p=.002, p=.044), confidence and resilience among sub-domains of psycap increased significantly(p=.006, p=.015). Finally, peer teaching have increased self-leadership and psycap of nursing freshmen. Therefore, further studies are proposed to apply various types of peer teaching in nursing curriculum.

Information and communication brings us some degree of convenient but also serious side effects. Especially, information and communication ethics is an important issue for elementary school children who are early stage in moral value. This paper proposes a triple-connected teaching and learning model. which can be applied to the elementary school children. in order to improve the educational level. The model is formed by selecting three discretionary teaching models, and applying independently them into the different classes with linking the contents for each class. A teacher can choose the teaching models based on what he wants to teach. Caring model, Home-Connected model and Simulation model were linked in our experiment. Experiments were conducted in the same condition but different learning models, Then, an educational effect was compared and analyzed in the educational level improvement point of view, between the Triple-connected teaching and learning model and the single teaching and learning model.

The purpose of this study was to empirically investigate the relationship among physical education professor-trust, attitude in physical education and self-management which pre-service elementary school teachers perceive. For this purpose, data from 328 students in universities of education located nationwide were collected and analyzed. Descriptive statistics analysis, reliability analysis, correlation analysis were conducted on the collected data by using IBM SPSS 23.0 statistical program, and confirmatory factor analysis and verification on structural equation model were conducted by using IBM AMOS 23.0 program. Through this research process, following conclusions were obtained; First, prospective elementary school teachers' confidence in physical education has a significant effect on attitude in physical education. Second, prospective elementary school teachers' attitude in physical education has a significant effect on class satisfaction. Third, prospective elementary school teachers' confidence in physical education has a significant effect on class satisfaction.

The purpose of this study was to develop and apply the elementary teacher training course for educational programming language based on TPACK in order to make elementary school teachers fully equipped with teaching efficacy for SW education. As a result, the informatics teaching efficacy of the teachers in the experimental group who participated in EPL training course developed based on TPACK was statistically more significant than the teachers in the control group(t=4.13, p<.001). The dependent sample t-test of the experimental group showed a statistically significant increase with t=4.57 (p< .001). It proved that TPACK-based teachers' training course is effective to improve teachers' informatics teaching efficacy. It is suggested that the development of SW education teacher training course should be systematically structured considering TPACK framework.

This study aims to analyze the causal relationship among teaching, cognitive, social presence and the learning outcome. It also provides the base data on the development of cyber education and its management strategies. During the first semester of 2009, 802 students at W cyber university completed surveys about their learning experience in teaching presence, cognitive presence, social presence, and learning outcome. The results indicated that there was a meaningful effect of teaching presence and cognitive presence on satisfaction, and that of cognitive presence on academic achievement. Based on these results, this study suggests instructional design methods and management strategies to improve the quality of learning in cyber universities.

The objective of this study was to investigate the impact of ego-resilience and compassion satisfaction on professor trust in nursing students. This was a descriptive survey that one hundred and sixty-one first- to fourth-year students of a university in D city who signed an informed consent form to participate in this study were enrolled. The collected data were analyzed using regression analysis. The regression was performed using peer relations, ego-resilience, and compassion satisfaction as the predicting variables. The results showed that peer relations (β=0.142, p=.020), ego-resilience (β=0.322, p<.001), and compassion satisfaction (β=.370, p<.001) predicted professor trust, and they explained 31.1% of the variance. Therefore, it is suggested to develop interventions to improve professor trust through school-year-specific counseling that enhances nursing students' ego-resilience and compassion satisfaction.

This study examined the job competence of the staff at the center for teaching and learning(CTL) in university and to find out the level of job competence, which has been asked to the staff of the CTL. For that, the factor of the job competence, which is required of the staff of the CTL, was inquired through a literature review. Based on the job competence, this study examined the required job competence of the staff in Daejeon city and Chungnam province. The result suggests that the job competence required of staff are the basic job competence, planning-analysis job competence, management job competence for the project, and evaluation job competence. The first factor in basic job competence is the attitude to change and innovation. In the planning-analysis job competence, the first factor is an analysis and consultation of instruction. In managing the job competence for the project, the first factor is the management of human resources, and the first factor in evaluating the job competence is an evaluation of the effectiveness of the media. Therefore, to revitalize the CTL, there is a need to organize an expert pool, plan and support program that is suitable for professional development.
