최근 비대면 원격강의의 비율이 증가하였지만 비대면 상황에서 원격으로 진행하는 강의로 인해 강의를 수강하는 학생들의 강의를 진행하는 교수와의 질문에 대한 즉각적인 상호작용과 피드백이 부족하고 교수 또한 비대면 상황에서 학생들과의 소통의 어려움으로 인해 질문에 대한 답변을 하는 것에 어려움 있다. 본 논문에서는 이러한 문제를 해결하기 위해 학생들에게 질문에 대한 즉각적인 답변을 해주고 교수에게는 질문-답변을 관리할 수 있는 인공지능 챗봇 웹 서비스를 제안한다. 웹 서비스는 강의를 수강하는 학생과 강의를 진행하는 교수로 나눠져 제공된다. 구현을 위해 Seq2Seq 모델을 활용하였고 질문-답변 데이터셋으로 학습을 하여 테스트 하였다.

In this study, the effects of reciprocal peer tutoring strategy on science achievement, science learning motivation, and self-esteem were investigated. Three classes of eighth graders (N=94) at a coed middle school were sampled for the study. They were divided into the comparison group, the cooperative learning (CL) group, and the reciprocal peer tutoring (RPT) group. Students were taught about the separation of mixtures for 13 class hours. Mid-term science examination scores were used as a blocking variable. The two-way ANCOVA results revealed that there were no significant differences among the three groups in the science achievement test, although the scores of the RPT group were higher than those of the comparison group. In all the subtests of the science learning motivation questionnaire, the scores of the RPT group were significantly higher than those of the comparison group. The scores of the RPT group were significantly higher than those of the other groups especially in the confidence part of the science learning motivation questionnaire. In the self-esteem test, the low achievers in the RPT group scored significantly higher than those in the CL group.

The objective of this study was to investigate the effect of an education method applying the flipped learning technique for college students. Both self-directed learning readiness and educational performance before and after applying the flipped learning were examined. After applying the flipped learning technique, teacher-student interaction, learning satisfaction, and learning motivation were identified. The correlation of each variable was examined after applying the flipped learning technique to investigate its influence on learning motivation. A total of 68 second-year nursing students enrolled in E University were analyzed. A difference between before and after applying the flipped learning was analyzed by the paired t-test; a correlation between the variables was analyzed via Pearson's correlation coefficient; and an influence on the dependent variable learning motivation was analyzed using the stepwise multiple regression analysis. The results showed that self-directed learning readiness increased before and after applying the flipped learning technique with statistical significance, and the difference of educational performance was not significant. After an education session applying the flipped learning technique, a learning motivation demonstrated a significantly positive correlation with self-directed learning readiness (r=0.33, p=.006), college student educational performance (r=0.51, p<.001), teacher-student interaction (r=0.72, p<.001), and learning satisfaction (r=0.79, p<.001). A significantly positive correlation was also observed between the other variables. Factors influencing learning motivation were learning satisfaction and teacher-student interaction. The explanatory power for learning motivation in the regression model considering these two variables was 71.3% (F=80.66, p<.001). Therefore, to enhance learning motivation in applying the flipped learning technique, it is necessary to increase learning satisfaction and to establish a strategy that further vitalizes the teacher-student interaction.

Science class is the starting point of science education where science teacher and students meet together to teach and learn science. Therefore successful science class is the main concern of various educational partakers, such as teachers, students, parents, school administrators, and science education researchers. In order to find what is important among the teaching abilities of science teachers, a survey was conducted to the various educational partakers. As the result of survey, students chose 'progressing a lesson' and 'teacher's attitude' are important, and in-service teachers chose 'analyzing learner characteristics and curriculum' and 'teacher-student interaction' are important, while the pre-service teachers and parents chose 'teacher-student interaction' and 'progressing a lesson' are important. In addition, the school administrators chose 'setting up teaching-learning strategy' and science education researchers chose 'understanding curriculum and developing teaching-learning method' is important along with 'analyzing learner characteristics and curriculum.' In the communication on science education among different educational partakers, these result can be used as the basic information to understand the different perspectives on a science class.

Cooperative teaching emerged as one of the interesting topics on curriculum administration and teaching-learning method in BSA(Busan Science Academy). The purpose of this study is to do research on social studies learning with respect to cooperative teaching, and to develop the model of cooperative teaching. The results of this study are as follows: First, We surveyed both the concept of cooperative teaching in all aspects and the methodological application on cooperative teaching. Second, We searched all teaching-learning methods in BSA in terms of cooperative teaching. Third, We studied cooperative teaching system on social studies considering current environmental factors. Forth, We performed seminar class which is constructed as one of the cooperative teaching models. The topic of seminar was 'The distortion and falsification of Koguryeo history in China'. The participants of seminar were volunteer students and social studies teachers whose subjects were geography, history, social studies, and ethics. And the participants conducted the research and cooperative learning based on teacher's subjects and subtopics. Fifth, The interactions between teacher and teacher, student and student, and teacher and student in the process of seminar preparation and publication were conducted very excitedly. Especially we found the possibility of cooperative teaching by the interaction between teachers. Finally, students developed the mind-frame to participate in social studies learning actively, and learned the method to research social affairs for themselves, and extended the eyes to approach social affairs with different opinions.

This study sought to investigate the effects of cooperative learning emphasizing interactions on science-gifted elementary students' scientific creativity. Thirty-four science-gifted elementary students were divided into an experimental class and a comparison class to compare their creativity scores quantitatively. The experimental class participated in cooperative learning emphasizing interactions, and the comparison class participated in whole class interactions. For qualitative analysis, the small group discussions were audiotaped and transcribed. The results of the study are as follows. First, cooperative learning emphasizing interactions had a positive educational effect on usefulness, which is one of the essential elements of scientific creativity. Second, as the cooperative learning progressed, the interaction between the small group members improved qualitatively. Third, the factors hindering the effectiveness of cooperative learning included negative task-unrelated statements from some of the small group members and the following operational statements to correct them. Based on these results, this study proposed some suggestions for effective cooperative learning emphasizing interactions.

The purpose of this study was to develop elementary science programs that used multi-level instruction and to analyze verbal interaction patterns in science classes that applied these programs. For this study, the 27 children from the fifth grade at B elementary school, located in Gyeonggi-do, were selected and separated into heterogeneous groups of four students. Verbal interactions occuring in two groups during each class were recorded using video. Elementary science programs using multi-level instruction were developed to target a fifth grade second semester 'Lesson 1. Human Body'. This program provided a mission form for each group and evaluation form for each child. A mission form depending on the children's level has different colors and levels of difficulty for questions. The evaluation form is composed of questions suitable for a child's level in reaching the goal with key concepts. The verbal interaction was mostly categorized into the cognitive domain and the affective domain for analysis. The cognitive domain was subdivided into question, response, making solution, receiving opinion, and the affective domain was divided into behavioral participation and students' attitude. Results of study showed that the frequency of the cognitive domain was higher than the frequency of the affective domain. In the cognitive domain, the median-level was of highest frequency in the children. In the affective domain, high-level was of highest frequency in the children. In terms of both the cognitive and affective domains of children, low-level exhibited the lowest frequency. Verbal interaction frequency was no difference between high-level and median level in cognitive and affective aspects, so median-level children were actively participating in activities similarly with high-level children. There were more types of interactions question, response, making solution, students' attitude in the median-low level children's verbal interaction than high-median level children's verbal interaction.
