Appropriate distribution and utilization of learning time in class are regarded as essential and basic conditions for successful education. Nonetheless, among studies about UCR(User Created Robot) based instruction so far is difficult to find the research related to the class. For these reasons, we attempt to analyze the ALT(Actual Learning Time) and unuse of learning time in UCR based instruction. For these purpose, we observed three students who were with third and fourth grade integrated class of elementary school and interviewed the teachers at pre-post class. The result of this study showed the following results: (1) UCR based instruction present lower ALT than traditional classes. (2) Most of the unnecessary time used in their classes tend to be used in preparing and arranging the robot module, a little is used unnecessarily because of the students' unrelated behaviors for their learning, decentralized behaviors and other external influences.

수업시간에 강의 듣고, 집에서 숙제를 하는 방식은 더 이상 학습자의 학습동기를 이끌지 못하고, 효과적인 수업이 이루어 질 수 없다. 수업시간에는 학생들의 적극적 상호작용이, 집에서는 인터넷 환경을 통한 핵심 강의식 내용을 미리 듣고 수업 활동에 임하는 플립러닝에 대한 영어과 수업의 도입이 필요하나 이에 대한 연구가 충분하지 않은 실정이다. 이에, 본 연구를 통해 영어수업(독해중심)에서의 플립러닝 활용 수업 모형을 개발하고, 이를 현장에 적용 후 수정 보완하여 대학 영어수업에서의 플립러닝 정착 및 발전을 도모한다.

비실시간 온라인 수업은 학습자가 원하는 시간에 학습을 할 수 있고, 공간의 제약이 없다는 장점이 있다. 그러나 실시간으로 이루어지는 수업이 아니다 보니 수업 콘텐츠에 문제가 있거나, 설명이 부족한 부분에 대한 학습자들의 의견이 교수자에게 전달하는 것에 한계점이 존재한다. 본 논문에서는 수업 콘텐츠를 듣는 학습자들의 피드백 정보를 교수자에게 전달하는 시스템을 제안한다. 학습자에게는 온라인 녹화 수업 콘텐츠를 정지했을 시 정지 사유를 조사하고, 정지 사유와 정지한 콘텐츠의 시간 정보를 교수자에게 전달할 수 있고, 교수자에게는 학습자들의 온라인 녹화 수업 영상의 피드백 정보와 정지시간을 교수자에게 그래프로 나타내어 한눈에 수업 콘텐츠의 문제점이 많은 부분을 파악할 수 있게 해서 전달한다. 교수자는 피드백을 반영해 콘텐츠를 재업로드하여 질 높은 수업 콘텐츠로 인해 학습자들은 학업 성취도를 높일 수 있을 것이다.

This paper examines the impacts of introducing Five-day school week in South Korean on adolescents' time use. Exploiting the exogenous variation in the adolescents' time at school on Saturday, I estimate the causal effect of change of adolescents' discretion time on their time use. The main findings are as follows. The introduction of the five day school week increased the adolescents' discretion time and their time spent on sleeping, passive leisure(mainly watching television). A one-minute decrease in the adolescents' time at school increase their sleeping time by 0.46 minute and passive leisure time by 0.26 minute.

프로그래밍 교육은 프로그래밍에 필요한 지식 교육부분과 문제해결능력과 연관된 프로그래밍 전략을 교육하는 부분이 함께 필요하다. 프로그램 작성 기술을 교육하는 과정은 단순한 지식 습득과정이 아니므로 수업과정에서 학습자 스스로 문제해결능력을 배양할 수 있는 유도과정이 필요하다. 이러한 특성의 프로그래밍 수업의 대표적인 수업방식은 실습방식으로, 실제 수업에서 학습자들의 서로 다른 수준을 고려하면서 실습수업을 효과적으로 운영하기에는 수업시간에 대한 제약이 많이 발생한다. 본 연구에서는 프로그래밍 교육에서 사전 프로그래밍 과제를 활용하여 주어진 학점과 시간 안에서 실습 중심의 학습 효과를 높일 수 있는 교수 학습 모델을 제시한다. 이를 통해 프로그래밍 언어 교육 과정에서 발생하는 제한된 실습수업 시간으로 인해 학습자 스스로가 문제해결능력을 배양할 수 있도록 유도하는 수업을 실시하는데 발생하는 어려움을 해결하여, 학습자가 문제해결능력을 향상시키고 좋은 프로그램 작성 기준에 적합한 프로그램 개발 능력을 배양하는 결과를 얻을 수 있었다.

This study simulates cases with 20, 30, 40, 50, 60 and 100 students and 6 values as the parameter of mu. Using the simulation, an analysis was made of how the number of students that couldn't concentrate during class increased over the duration of time. When normalizing the difference in student number when the value of mu is constant, there was a decrease in percentage over time. It also showed a change in percentage when the value of time is fixed while the value of mu changes. Based on the result values, by estimating the mu value with the class atmosphere to predict the outcome and improve the lecture.

The purpose of this study is to investigate middle school students' perceptions of private academy science education and of school science education in order to promote school science education. 180 middle school students who were taking a science class at a private academy were participated, and the short form of Classroom Environment Scale was implemented for the study. The results showed that the students went to an academy for supplementing school science or for getting a better grade in school. Some students, however, have different reason to go to an academy; they were kinds of silence-learners or received-learners rather than constructed-learners. That is, they didn't know how to and what to study. Students didn't have an opportunity to think scientifically and creatively from both academy and school science classes. They studied harder in science class at private academy than at school. Some students felt more favorable to and comfortable with academy teachers compare to school science teachers.

본 연구에서는 컴퓨터공학의 대표적인 교과목인 알고리즘 교과목에 대하여 거꾸로 학습을 적용한 결과를 보여준다. 학생들은 집에서 온라인 컨텐츠로 학습을 하고 수업 시간에는 숙제를 수행하는 방식으로 수업을 진행하였다. 수업시간에 진행하는 과제는 그룹 과제와 개인 과제로 구성되어 있어, 토론을 활성화 하여 학습 효과를 높이도록 하였다. 성과 분석 결과, 거꾸로 학습이 전통적인 수업에 비하여 동등하거나 또는 더 나은 효과가 있음을 보여 주었다.

The study applied a narrative inquiry to the undergraduate interdisciplinary course taught for three years(2012~2014). Narratively I have described interactions among teachers' and students' performing the interdisciplinary consilience course with various situations such as place, curriculum and class interaction. I have specifically illuminated a three-dimensional narrative inquiry space embracing the dilemma of the consilience curriculum, PBL(Problem Based Learning) and TBL(Team Based Learning), and an effective presentation. The result of the study is as follows: First, the ratio of giving lecture is high. The burden of doing project will be reduce if the teacher decreases the lecture up to one fourth, gives students enough time to finish their tasks, and gives them advice for a better project. Second, for opening the interdisciplinary consilience class maintaining previous college curriculum, each department has to put a 'consilience course' on the existing curriculum that allows teachers open the consilience course whenever they need to teach with other department teachers. Third, an effective teaching method using the PBL(Problem Based Learning) in Team Based Learning environment is making students to consider projects as problem situations to solve and to apply the problem situations to PBL method. Lastly, teachers should give students lots of opportunities for presenting what they have learned in the class. Three times of presentation as a team member is ideal in a semester but the way of presenting has to be changed. The students in next year will relieve the tension of 30 minute instead of 15 minute, two days instead of one day for the team presentation.

Seeing the elapsed time as a quantity that can be measured is quite challenging for students while making students see it is also challenging for teachers. Tuning on these challenges, this article reports on what learning opportunities elementary teachers provide when they teach elapsed time focusing on quantitative objectification. I observed three mathematics classrooms where the elapsed time was taught by three elementary teachers and did a narrative analysis on the instructions. All three teachers utilized certain tools to support students access to the elapsed time as a quantity. They appropriated various quantitative attributes of the tool. In the case of the analog clock, one teacher tried to quantification the elapsed time with the number of minute hand's turning, while the other teacher indicated the distance of minute hand's moving. One teacher represented the elapsed time with the longitudinal attribute of the time band. Standing on the findings, the didactical implications of various attempts for quantitative objectification of the elapsed time implemented were discussed.
