Korean elementary school facilities are a lot of changes since the mid-1990s. Creative learning ability to become more important. Interior space environment and the hardware changes needed improvement. In this study, depending on the teaching methods and curriculum characteristics to suggest design guidelines for a more effective lesson plan by changing the terran out. Open education free to enhance the development and creativity of the human spirit, the human, and realize the value of education is to increase the relevance of education for self-realization and social. Space for open educational practices through advanced layout is proposed. There is a need for the development of new school furniture for a variety of lay-out. It is important to develop a spatial variability in new school furniture.

본 논문에서는 오픈 소스 컴퓨터 비전 라이브러리 중 하나인 OpenCV를 사용하여 차선 인식 기능을 구현한 내용을 정리하였다. ARM 프로세서 기반인 Raspberry Pi 3 보드에 Linux 운영체제인 Rasbian(r18.03.13)을 탑재하였고, 영상처리를 수행하기 위해 Raspberry Pi Camera를 사용하였다. 차선인식을 구현하기 위해서 OpenCV 라이브러리에 구현된 Canny Edge Detection, Hough Transform 알고리즘을 사용하였고, 소실점(Vanishing Point)의 흔들림을 방지하고 원하는 직선만을 검출하도록 RANSAC 알고리즘을 사용하였다. 또한, 검출된 차선에 따라 자동차가 주행하도록 DC모터와 Servo모터를 제어하였다.

The purpose of this study was to analyze the complexity of scientific reasoning during open inquiry activities of pre-service elementary school teachers. In this study, 6 pre-service elementary teachers who participated in open-inquiry activities were selected. The data of scientific reasoning during their inquiry process was collected from the video recording of reporting about inquiry process and results, their reports and researcher's notetaking. CSRI Matrix (Dolan & Grady, 2010) was used to analyze the complexity of participants' scientific reasoning. The result showed that the degree of the complexity of their scientific reasoning varied in participants. Particularly the low degree of the complexity of scientific reasoning presented in posing preliminary hypotheses, providing suggestions for future research, communicating and defending finding. Also, The more pre-service teachers' epistemology of inquiry are similar to that of scientists, the more complex scientific reasoning represents. This results suggest that teachers should impress on students the importance of doing the precedent study and providing suggestions for future research, and provide a place for communicating and defending findings.

본 논문에서는 다양한 Open APIs 를 교육적으로 활용할 수 있는 동영상 부가정보 제공 시스템을 개발하였다. 교사들은 이 시스템을 사용하여 기존의 일반적인 동영상을 교육목적에 맞게 재구성할 수 있다. 특히 교사들은 어려운 프로그래밍 작업 없이도, 단순한 키워드 입력만으로 다양한 Open APIs를 손쉽게 가져와 활용할 수 있을 것이다. 또한 동영상 키워드 정보를 적응적으로 관리함으로써 학생들에게 수준에 맞는 내용을 제공할 수도 있다. 학생은 키워드 정보를 적응적으로 제공받음으로써 동영상 내용을 쉽게 이해할 수 있으며 지식의 확장에 도움을 받을 수 있다.

The purpose of this study was to compare the science philosophical views and instruction strategies for open-inquiry between teachers of science-gifted and teachers of general students. The subjects were 45 teachers of science-gifted and 45 teachers of general students. The major results of this study were as follows: First, there was no differences on the science philosophical views between teachers of science-gifted and teachers of general students by chi-square tests (p<.05). Second, there were no differences on how task assignments, how to guide exploration data, and how to write reports between teachers of science-gifted and teachers of general students (p<.05). But there was meaningful differences on how to proceed with exploration activities between teachers of science-gifted and teachers of general students (p<.05). It is implied that this the results of this investigation will help the focus of future efforts to promote more adequate the science philosophical views and instruction strategies for open-inquiry in teachers of science-gifted.

WHAT we teach, and HOW students experience it, are the primary factors that shape students' understanding and beliefs of what mathematics is all about. Further, students pick up their sense of mathematics from their experience with it. We have seen the results of the approach to "break the subject into pieces and make students master it bit by bit. As an alternative, we strive to create a teaching environment in which students are DOING mathematics and thereby engender selected aspects of "mathematical culture" in the classroom. The vehicle for doing this is the so-called Japanese Open-ended approach to teaching mathematics. We will discuss three aspects of the open-ended approach - process open, end product open, formulating problems open - and the associated approach to assessing learning.

The purpose of this study was to understand the teaching effects according to the cognitive levels after conducting inquiry activities using science notebooks in the open inquiry activities of the elementary science class. The results of this study were as follow. first, students having the open inquiry activities using science notebooks showed improvement in scientific inquiry abilities in both groups with the low and high cognitive level. Second, regarding the changes of scientific attitudes, both groups with the low and high cognitive level exhibited improvement. According to the result of analyzing interaction between the cognitive level and class treatment on the effects for scientific inquiry abilities and scientific attitudes, there was no difference by the cognitive level. And the use of science notebooks in open inquiry activities had effects on improving scientific inquiry abilities and scientific attitudes regardless of the cognitive level.

The purpose of this study is to analyze the interaction patterns and the commonly accepted norms of reaching a consensus among small-group children when solving open-ended problems. In conclusion, open-ended problems have various strategies or different acceptable answers, so they give children learning opportunities to compare the answers and to participate in communication. And more valuable interaction patterns come from 'measuring','classifying' problems and open-ended problems with implicit solution. Therefore, teachers might as well consider the relation between problems and interaction patterns when they pose open-ended problems in a small-group study setting. They are expected to empower children to have sociomathematical norms of reaching a consensus un der indirect and supportive guidance.

The purpose of the study is to investigate how children and preservice teachers would make a progress in solving the open-problems related to area. In knowledge-based information age, information inquiry, information construction, and problem solving are required. At the level of elementary school mathematics, area is mainly focused on the shape of polygon such as square, rectangle. However, the shape which we need to figure out at some point would not be always polygon-shape. With this perspective, many open-problems are introduced to children as well as preservice teacher. Then their responses are analyzed in terms of their logical thinking and their understanding of area. In order to make students improve their critical thinking and problem solving ability in real situation, the use of open problems could be one of the valuable methods to apply.
