The purpose of this study is to examine the effects of applying the Question-Answer Relationship (QAR)strategy on the attitude toward science of the elementary fifth grade students whose learning styles have beenidentified. The population of the study constitutes the total of 97 elementary fifth grade students who wereassigned into a comparison (n=48) or experimental group (n=49). To understandhow the QAR strategy potentially influencedscientific attitude, both groups were surveyedin the areas of scientific attitude before and after the experiment. TheKolb's Test was used to identifythe students' learning stylein the experimental group. According tothe learners' learning style, the results have been compared and analyzed. The results of this study are as follows:First, the findings revealed a significant difference in the experimental group students' attitude toward sciencecompared to the comparison group. Second, four learning styles were identified among the studentsin theexperimental group: a) Accommodators (46.9%), b) Convergers (24.5%), c) Divergers (20.4%), and d) Assimilator (8.2%). Following the data analysis, there was no meaningful statistical difference between four groups oflearning styles with respect to their scientific attitude.Applyingthe QAR strategy in a science class seemed toimprove the accommodators, convergers, and divergers' scientific attitude positively.

In this paper, various platforms are designed, where instructors and students can communicate each other to educate, ask and answer the questions interactivel under the WEB 3-based remote real-time instrurtions. The proposed system maximizes involvements among the students, instrurtors and administrators, which facilitate the understanding and progressive developments of the lessons and tasks to be performed. In the proposed education system, the instructors work as overseers for the study and the students benefit from comparative learning and pattern design. Also, the advantages of WBI are maximized, and the common factors among the mutual components are extracted and reused to avoid the confusion for the students. The advantages of the components are maximized and applied to the proposed system.

대학에서 실행되고 있는 정보활용능력 교육에 따른 학습자의 정보활용능력에 대한 자가인식의 변화는 학습자의 특성에 따라 차이가 나타날 수 있다. 이에 본 연구에서는 정보활용능력 교육의 효과에 영향에 미치는 학습자의 영향 요인을 조사 분석하고자 하였다. 본 연구의 목적을 위해, D 대학의 한 학기 교양과목으로 개설되고 있는 정보활용능력 교육 프로그램을 대상으로 해당과목 수강생 47명의 정보활용능력에 대한 자가 인식을 교육전과 교육후의 질문지법을 통해 그 변화를 조사 분석하고 이들 학습자의 개인적인 특성을 파악하였다. 학습자의 특성에는 인구통계학적인 특성 이외에 유사 교육 프로그램 경험 유무, 도서관에 대한 인식 등이 조사되었다. 정보활용능력에 대한 자가 인식을 측정하기 위한 문항들은 ACRL의 고등 교육자를 위한 정보활용능력 평가기준을 참조하였고 사용된 분석도구는 Excel과 SPSS 17.0이다.

In Web Based Instruction, as evaluation of learning process means individual student's learning activity, it demands data on learning time, pattern, participation, environment in a specific learning contents. The purpose of this paper is to reflect analysis results of individual student's learning status in achievement evaluation using the most suitable web log mining to settle evaluation problem of learning process, an issue in web based instruction. The contents and results of this study are as following. First, conformity item for learning status analysis is determined and web log data preprocessing is executed. Second, on the basis of web log data, I construct student's database and analyze learning status using data mining techniques.

In this research, we investigated the effect of arithmetic learning utilizing mathematical mobile application on arithmetic fluency and learning motivation of underachieving students in math. 24 4th grade math underachievers were divided into control and experimental groups. Arithmetic learning utilizing mathematical mobile application was conducted for experimental group and arithmetic learning utilizing learning worksheets was conducted for comparative group. After three weeks, the experimental group showed increase in math fluency and motivation compared to control group. Implications are discussed.

본 연구에서는 먼저, 수학교사에게 필요한 지식으로 교과, 학생, 교수학적 내용 지식이 필요함을 문헌을 통해 정리하였다. 교사의 지식과 수업 실제에 관한 세 편의 논문을 분석한 결과 교사의 수학에 대한 충분한 이해가 학생의 학습과 효과적인 교수에 절대적인 영향을 미친다고 주장할 수 없음을 알 수 있었다. 그러나 수학에 대한 바른 이해는 학생의 질문에 적절한 반응을 할 수 있도록 하며, 수업을 계획하고 교실에서 이루어지는 담화를 수학적으로 원활하게 조절할 수 있도록 도움을 줄 수도 있었다. 따라서 수학을 잘 아는 것이 효과적인 교수·학습을 보장하지는 못하지만, 교사가 잘 알지 못하는 것을 가르칠 수는 없다는 결론을 얻었다.

자연어 처리는 인공지능의 핵심기술 중 하나이다. 그 중 오픈 도메인 챗봇 구현은 NLP 에서 어려운 태스크로 꼽힌다. 명확한 목표, FAQ 가 존재하는 기능형 챗봇과 달리 오픈 도메인 챗봇은 연속적 대화, 방대한 양의 상식 등 구현에 어려움이 많았다. 짧은 질문과 대답으로 이루어진 데이터로 학습한 모델을 대화 데이터로 학습시켜 좀더 자연스러운 챗봇을 구현해보고자 한다.

최근 자연어 처리 분야에서 기계학습 독해 관련 연구가 활발하게 이루어지고 있다. 그러나 그 중에서 한국어 기계독해 학습을 통해 문제풀이에 적용한 사례를 찾아보기 힘들었다. 기존 연구에서도 수능 영어와 수능 수학 문제를 인공지능(AI) 모델을 활용하여 문제풀이에 적용했던 사례는 있었지만, 수능 국어에 이를 적용하였던 사례는 존재하지 않았다. 또한, 수능 영어와 수능 수학 문제를 AI 문제풀이를 통해 도출한 결괏값이 각각 12점, 16점으로 객관식이라는 수능의 특수성을 고려했을 때 기대에 못 미치는 결과를 나타냈다. 이에 본 논문은 한국어 기계독해 데이터셋을 트랜스포머(Transformer) 기반 모델에 학습하여 수능 국어 문제 풀이에 적용하였다. 이를 위해 객관식으로 이루어진 수능 문항의 각각의 선택지들을 질문 형태로 변형하여 모델이 답을 도출해낼 수 있도록 데이터셋을 변형하였다. 또한 BERT(Bidirectional Encoder Representations from Transformer)가 가진 입력값 개수의 한계를 극복하기 위해 더 큰 입력값을 처리할 수 있는 트랜스포머 기반 모델 중에서 한국어 기계독해 학습에 적합한 KoBigBird를 사전학습모델로 설정하여 성능을 높였다.

The Current 7th Curriculum for Computer Education emphasized the class of practice oriented, student oriented. But it is very hard because of many students, poor environments, insufficiency of the teaching model. So ADPM will gives our help. a ADPM based practical class using ebook synchronized with video files give a little student's wating time for answering, much student's learning efficiency, much student's voluntary learning custom, a individualized learning. And this study developed the prototype to support the ADPM. This prototype will make up for the weak points in authoring systems, which they are a wizard type program, capturing video file, synchronizing video files. And it will improve a practical class.

This study is a qualitative study to grasp the meaning of the effective role of tutors of college students experiencing problem-based learning through focus group interviews. The subjects of this study were 4th grade students in the Department of Nursing who had experienced PBL, and a total of 21 people were divided into 3 groups and interviewed. Data were analyzed in content to find meaningful topics. The results of this study were analyzed into two subjects and eight categories. Based on the research results, if we summarize the role of effective tutors recognized by students in PBL. 1) Create a permissive atmosphere so that students can express their ideas freely and interact. 2) Give praise and encouragement. 3) Encourage all learners to participate. In particular, learners with low participation should be asked questions to promote active discussion. 4) Avoid unnecessary intervention and participate in the discussion together. 5) Adjust the learning speed and manage the time well. 6) Develop a scenario that meets the goals. 7) Classes are run around questions that can promote learners' thinking. 8) It plays a role of helping to form knowledge by providing positive feedback to learners' responses.
