본 연구에서는 CAl가 고등학생들의 개념 이해도, 수리문제 해결능력, 학습 동기, 그리고 화학에 대한 태도에 미치는 효과를 조사하였다. CAl 프로그램은 물질의 동적인 입자성을 강조하기 위해 애니메이션을 사용하여 분자 운동을 제시하였고, 이해-계획-풀이-검토의 4단계 문제 해결 전략에 대하여 학습자의 반응 유형에 따라 각 단체별로 즉각적인 피드백을 주도록 구성하였다. 서울시에 소재한 여자 고등학교 두 반을 선택하여 기체 법칙에 대하여 4차시 동안 CAl와 전통적 수업을 실시하였다. 분석 결과 화학 개념 검사, 화학 수리문제 해결능력 검사에서 CAl 집단 학생들의 검사 점수가 통제 집단에 비해 유의미하게 높았다. 또한, CAl 집단 학생들의 학습 동기 및 화학 수업에 대한 태도가 통제 집단 학생들에 비해 유의미하게 향상되었다.

We propose an adaptive unmanned aerial vehicle (UAV)-assisted object recognition algorithm for urban surveillance scenarios. For UAV-assisted surveillance, UAVs are equipped with learning-based object recognition models and can collect surveillance image data. However, owing to the limitations of UAVs regarding power and computational resources, adaptive control must be performed accordingly. Therefore, we introduce a self-adaptive control strategy to maximize the time-averaged recognition performance subject to stability through a formulation based on Lyapunov optimization. Results from performance evaluations on real-world data demonstrate that the proposed algorithm achieves the desired performance improvements.

Purpose: The purpose of this study was to develop a self-directed e-learning program for ICU nurses and to evaluate how the proposed e-learning program affects the level of knowledge, nursing performance and job satisfaction of ICU nurses. Methods: The e-learning program was developed with the Computer Assisted Instruction Design Model using sources of self-efficacy which included the inactive attainment, vicarious experience, and verbal persuasion of ICU nurses. The program was evaluated by experts. Following the revision of the program, it was applied to a total of 59 ICU nurses (experimental group n=29, control group n=30) from three hospitals. Four weeks later, we measured the level of knowledge, nursing performance and job satisfaction. Results: The level of knowledge significantly improved in the experimental group (t=5.691, p<.001). Moreover, the level of nursing performance significantly increased in the areas of circulatory diagnostic test (t=2.143, p=.039), EKG (t=2.911, p=.006), aortic balloon pump (t=2.491, p=.017), and nebulizer therapy (t=2.085, p=.044). Overall, job satisfaction did not significantly increase (t=1.664, p=.105); however, job satisfaction in terms of relationships with coworkers (t=2.371, p=.023) and the needs of nursing performance (t=2.940, p=.006) were significantly increased. Conclusion: The results showed that the proposed e-learning program using sources of self-efficacy from ICU nurses was an effective learning method to increase the level of knowledge and nursing performance. The propose de-learning program would be a useful teaching tool for ICU nurses improving the quality of ICU patient care.

In this paper a Korean authoring system is designed to write a CAI courseware in Hangul/English by an author who is a nonprogrammer. It saves nock time in authoring a courseware and maintains high level transplantity among CAI systems. By interfacing ah expert graphic utility, image information can be processed more easily and efficiently. Programming control of the flow of CAI courseware can be ramification and individual learning possible, fitting various demands of learners and learning and learning ability.

원격 로봇보조학습은 신체적·지적·문화적·환경적으로 취약한 학생들에게 교육의 기회를 제공할 수 있으며, 농산어촌 고교학점제의 어학관련 과목의 온라인교육과정을 대체하거나 세계시민교육을 위한 국제교류학습에 활용할 수 있으나, 현재까지 수용모델 연구는 예비교사를 대상으로만 이루어졌으며 사후사용의도 요인은 고려하지 않았다. 따라서 본 논문은 초등교사를 대상으로 원격 로봇보조학습에 대하여 사용의도와 사후 사용의도에 영향을 주는 기초 요인을 알아보았다. 연구 결과, 원격 로봇보조학습에 대하여 초등교사들은 성별에 의해 각 요인이 유의미한 차이가 없었으며, 경력이 많은초등교사들이 FC, PAD, PS, SP에서 더 긍정적으로 유의미한 결과가 나왔다. 또 수용의도에 영향을 주는 요인으로 PU, ATT, PENJ, SI, Ttrust 모두 매우 유의미 있게 나왔다. 이와 같은 원격 로봇보조학습에 대한 초등 교사들의 수용의도를 바탕으로 교육정보 정책 수립을 할 수 있을 것이다.

We conducted a comprehensive review on the previous research on r-Learning. By reviewing 843 previous studies about r-Learning published from 2004 to 2015, this study investigated 1) the trend of research on r-Learning over time, 2) the characteristics of targeted students in r-Learning, 3) the educational activities implemented for r-Learning, and 4) the types of educational robots used for r-Learning. The study found that the research on r-Learning has rapidly and steadily increased and the types of educational activities and educational robots has been diversified. Relying on the findings of this review, this study suggests 1) ensuring growth in both the quality and the quantity of research on r-Learning, 2) broadening the target student population of r-Learning beyond the age-limited boundaries, 3) enhancing educational activities of r-Learning, and 4) recognizing the necessity for systematic and clear concepts of types of educational robots.

Extended reality-assisted training offers repeatable learning opportunities at a low cost. This paper proposes a smart glass application for training core nursing skills to nursing students, who often need to memorize and practice training sequences. The proposed smart glass application interactively presents a series of instructions to help students remember and perform two core nursing skills in the correct order. We conducted a usability test on 30 undergraduate nursing students in their third year using the smart glass application. Our initial findings show that many students have positively evaluated the possibility of using smart glasses for training, but have also encountered several challenges with the smart glass application's user interface, which takes time to adapt.

This study aims to investigate the effects of the implementation of self-directed learning through the homepage between the teacher and the students for English reading classes. The study focuses on the questions of whether the self-directed learning through the homepage, compared to the teacher-centered learning, would enable a significantly positive change in the students' achievements and of what their responses to this new learning method are. 72 students were grouped into an experimental and a control group, and then each group was subdivided into three levels (high, medium, low) of proficiency. Findings demonstrate that the experimental group showed statistically more significant increases in their scores of reading proficiency test than the control group. For the question of students' responses to the learning experience, the three groups within the experimental group responded to a questionnaire survey with regard to the positive attitude of learning, the effectiveness of self-directed learning and its learning materials, and usability of the homepage. In general, the experimental group considered the experience satisfactory, although the degree of positive responses varied according to the proficiency level of the group. This suggests the importance and effectiveness of self-directed learning using the computer and internet as a supplementary learning tool.
