학습 수준의 평가와 수준에 맞는 지식의 제공은 인간의 학습 과정에 많은 영향을 준다. 이것은 학습 순서가 중요하다는 것을 말하고 있으며, 기계 학습에서도 학습 순서를 고려할 필요가 있다. 본 연구는 학습 순서가 학습에 미치는 영향을 알아보기 위해, MLP의 학습에서 지도자의 경험을 이용하여 학습순서를 제어하는 방법을 제안한다. 지도 경험과 평가를 이용하여 MLP의 상태를 파악하고, 현 상태에서 학습 효율이 좋을 것으로 예상되는 학습 자료를 선택하여 학습을 시킨다. 지도자의 경험을 표현하고 활용하기 위해 CRF(Conditional Random Fields)를 이용하였다. 제안한 방법은 학습 자료를 선택한다는 점에서 능동 학습(Active Learning)과 유사하지만, 학습 순서를 제시하기 위한 자료의 선택이란 점에서 능동학습과는 차이가 있다. 분류 문제에 대하여 실험해 본 결과, 순서의 제어가 없는 학습의 경우에 비하여 학습 횟수의 측면에서 일반적으로 더 나은 학습 성능을 보여준다.

Linking Ukraine's education system with the trends of global digitalization is mandatory to ensure the sustainable, long-term development of the country, as well as to increase the sustainability of the education system and the economy as a whole during the crisis period. Now the main problems of the education system in Ukraine are manifested in a complex context caused by Russian armed aggression. In the context of war, problems include differences in adaptation to online learning among educational institutions, limited access to education for vulnerable groups in the zone of active hostilities, the lack of digital educational resources suitable for online learning, and the lack of basic digital skills and competencies among students and teachers necessary to properly conduct online classes. Some of the problems of online learning were solved in the pandemic, but in the context of war Ukrainian society needs a new vision of education and continuous efforts of all social structures in the public and private environment. In the context of war, concerted action is needed to keep education on track and restore it in active zones, adapting to the needs of a dynamic society and an increasingly digitized economy. Among the urgent needs of the education system are a change in the teaching-learning paradigm, which is based on content presentation, memorization, and reproduction, and the adoption of a new, hybrid educational model that will encourage the development of necessary skills and abilities for students and learners in a digitized society and enable citizens close to war zones to learn.

본 연구는 온라인 대학의 성인 학습자들이 지각한 교수자에 대한 사회적 실재감이 교수자의 사회적 촉진활동에 따라 어떻게 달라지며, 이것이 궁극적으로 학습만족도에 어떤 영향을 미치는지, 그리고 이와 관련된 학습자 변인은 무엇인지를 분석하는 데 목적이 있다. 이를 위하여 2014학년도 2학기 국내 한 온라인대학 재학생 119명으로부터 수집된 인구학적 정보, 상호작용, 교수자에 대한 사회적 실재감 및 과목 전반에 대한 사회적 실재감, 학업만족도에 대한 자료를 분석에 활용하였다. 연구목적에 따른 결과는 다음과 같다. 첫째, 교수자에 대한 사회적 실재감은 연령이 높은 집단에서, 자유게시판 활동에 참여한 집단에서 높았다. 둘째, 교수자의 사회적 촉진활동은 교수자에 대한 사회적 실재감을 높이는 데 기여했으나, 자유게시판 활동에 참여한 학습자들은 교수자의 개입이 없이도 교수자에 대한 사회적 실재감이 높았다. 셋째, 교수자의 사회적 촉진활동은 교수자에 대한 사회적 실재감과 유의미한 상관성을 보였으나 학습만족도에 대한 영향력은 교수자에 대한 사회적 실재감과 과목 전반에 대한 사회적 실재감에서만 나타났다. 본 연구를 통해 학습만족도를 높이기 위해서는 교수자의 사회적 촉진활동이 사회적 상호작용에 소극적인 학습자들에게 보다 체계적으로 제공되어야 한다는 점이 제안되었다.

It is reported that the constructivistic learning method (CLM) enhances the understanding of the students in the learning process, especially in engineering classes. In CLM-based classes, the students can take the initiative in the learning process, which is called the student-centered model of the learning process. This is different from the traditional learning method based on the teacher-centered model, where a teacher plays the central role in the learning process of students. The authors have applied the method of CLM to one of the Engineering classes, namely production planning and inventory control (PPIC) class for undergraduate students. The PPIC class provides multimedia-based study materials and factory visits as well as regular lecture sections to cover the whole subject of inventory control theory and practice. In the review sessions, students are divided into several groups, and question-and-answer discussions were actively carried out among these groups under the support of the teacher as a facilitator. It was observed that the student engagement in the class was very active compared to the conventional lecture-based classes. As for further support of students understanding on the subject, simulation-based materials are also under study for the class. This paper presents the review of case study of CLM-based PPIC class and discusses the feasibility of simulation-based study materials for further improvement of the class.

Purpose: This study was to evaluate clinical competence in relation to self-directed learning, critical thinking disposition, and participating in PBL(Problem-Based Learning) group activities of nursing students. Methods: Data were collected from 108 nursing students in Oct. 2006. Results: Clinical competence had a significant positive correlation with self-directed learning, critical thinking disposition, and participation in PBL group activities. There was a significant difference in clinical competence according to interpersonal relationship. Participation in PBL group activities was the most influential factor of clinical competence($R^2$=.34). Also, the influence of clinical competence increased with the addition of self-directed learning($R^2$=.42). Conclusion: It is essential to encourage the self-directed learning and participation in PBL group activities for the improvement of clinical competence. It is relatively important for clinical competence to consider the educational environment systematically.

The purpose of this study is to verify the mediating effect of interaction among learners in a Web Based Collaboration Learning (WBCL) environment. 254 Korean college students served as test subjects and during the 4 weeks of research period, they studied the Test of English for International Communication (TOEIC) in a web-based collaborative learning system. The interaction between learners was looked into by categorizing the concept into task oriented information sharing activities and relationship oriented communication activities and analyzing the causal relationship between the two activities. Learning performances were measured in individual level. The results are as follows. First, task oriented information sharing activities effect positively on relationship oriented information sharing activities. Second, the managerial characteristics of WBCL had a positive effect on interaction between learners but the systematic characteristics had partial influence on interaction between learners. Third, the interaction between learners completely interconnects the managerial characteristics of WBCL and learning performance but partially interconnects the systematic characteristic of WBCL and learning performance. In conclusion, this study implies that managerial and systematic characteristics of WBCL should be considered on the preferential basis for the WBCL to become successful and interactive activities such as information sharing and communication should be encouraged to be active from a small-size WBCL perspective.

Purpose: The purpose of this study was to identify the effectiveness of the JigsawⅣ cooperative learning in a facilitative communication class of nursing students. Achievement, communication skill, self-directed learning and experience during the class were measured. Method: This study was a pretest and posttest design with two subject groups. 43 students were in experimental (JigsawⅣ) group and 47 ones were in control (general small discussion) group. Classes were conducted over a 6-week period. The collected data was analyzed by the SPSS 12.0 program. Result: After taking part in the educational program, the experimental group had significantly more improvement in communication skill (F=6.81, p=.002) and self-directed learning (F=11.81, p=.000). In addition, the experimental group showed significantly higher scores for concentration in the class (t=2.26, p=.27), positive emotional state (t=3.01, p=.003) and active participation (t=2.78, p=.007) compared to the control group. However, the achievement between the two groups was not significantly different (F=3.29, p=.073). Conclusion: The findings of this study show that JigsawⅣ cooperative learning has positive effects in improvement of communication skill and self-directed learning. Also, students were excited and interested in the class during cooperative learning. Based on these findings, the author suggests developing additional educational programs focusing on nursing students.
