In this study, we suggest the standards for future mathematics classroom from environment, teachers, and students aspects. Future mathematics classroom should have the three environmental standards that perform responsible roles and appropriate functions of physical resources and classroom space. In the teacher standards' domain, we presented as a total of eight kinds. Concretely, we proposed the four standards for improvement of mathematical teacher's instructional expertise and the four standards for improvement of abilities of learners. The students standards consist of 4 domain a such as 3 standards of mathematical investigation and problem solving, 3 standards of cooperation and communication, 1 standard of utilization and operation of mathematical technologies and learning support systems, 2 standard of digital ethics and citizenship. Also, we developed the mathematical convergence instruction model and reported the results of its application after the lessons conducted in the classroom equipped with advanced environmental and technologies. We presented the convergence instruction model and scenarios focused on thoughts and actions of teachers and students in the future mathematics classroom.

Three workers, field operators in lubricating oil processing of petroleum refinery industry were found unconscious by other worker. One of them who were exposed to an high concentration of H2S was presented with Glasgow Coma Score of 5, severe hypoxemia on arterial blood gas analysis, normal chest radiography, and normal blood pressure. On hospital day 7, his mental state became clear, and neurologic examination showed quadriparesis, profound spasticity, increased tendon reflexes, abnormal Babinski response, and bradykinesia. He was also found to have decreased memory, attention deficits and blunted affect which suggest general cognitive dysfunction, which improved soon. MRI scan showed abnormal signals in both basal ganglia and motor cortex, compatible with clinical findings of motor dysfunction. Neuropsychologic testing showed deficits of cognitive functions. SPECT showed markedly decreased cortical perfusion in frontotemporoparietal area with deep white matter. Another case was recovered completely, but the other expired the next day.

디지털 교과서 상용화 시범 사업은 다양한 학습 지원 도구들과 사회 각 분야의 최신정보, 지식DB등을 활용하여 교실에서 참여형 학습을 실행할 수 있는 사업이다. 현재 디지털 교과서는 유통되고 있는 페이지 단위의 e-book형태가 아닌 확장 가능 구조로 개발되어 있어, 기존의 e-book 단말기나 e-book reader 프로그램에 바로 적용할 수 없다. 본 연구는 이러한 문제를 해결하기 위해 디지털 교과서 단말기의 요구 사항과 기존 단말기의 구현기능을 분석하여, 개선된 단말기의 기능과 규격을 제시하고, 이를 활용할 수 있는 교실 교육 환경을 제안한다.

The conventional school building design, which locates the hallway on the north side of the classroom, has proven to be very ineffective for indoor light control. Especially, glares and dark spots on the work plane as well as nonuniform illuminance on the chalkboard were causing undesirable visual effects for the students. The present study has investigated various problems with the classroom in the existing elementary and(junior) high school buildings from the point of indoor visual environment, and made some suggesions for possible solutions.

인간의 교수${\cdot}$학습은 본질적으로 뇌 기능과 많은 관련을 맺고 있기 때문에 뇌-기반 학습에서는 우리의 뇌가 최적으로 학습하는 방식에 기초해 접근을 시도한다. 지난 30년간의 뇌에 대한 연구는 교수${\cdot}$학습에 대해서 이용할 만한 많은 정보를 제시하고 있다. 많은 교육연구가들은 뇌 연구를 기초로 뇌가 최적으로 학습하는 뇌-친화적 환경을 도입하였고, Politano & Paquin(2000)은 현행교실에 실제로 이용 가능한 뇌-기반 환경을 창조하기 위한 기초로서 10가지 요소를 제시하면서 뇌-기반 학습에서 학습자는 자신에게 익숙한 학습감각을 가지고 있으며 그것을 통한 학습이 효과적임을 말하였다. 수학교육에서도 이와 같이 뇌-기반 학습을 배경으로 하는, 학습자의 학습감각을 고려한 교수${\cdot}$학습이 의미있다고 할 수있다. 본 연구에서는 뇌기반 학습의 의미를 고찰하고, 제 7차 교육과정이 실행되는 초등학교 4학년, 중학교 2학년, 고등학교 1학년에 교실에 대한 학습감각을 조사하였으며, 수학 교실에서 학습자의 학습감각을 고려한 수업활동을 제시하였다.

Focusing on both the form of open classroom and that of independent one which have been most planned and being built, this study was designed to see if the educational environment of their inner space, structure, and facilities gives a proper support to classroom activities during the various classes based on open education. Selecting representative teaching methods in elementary school, such as open simultaneous learning, learning through a medium, learning in the corner, subject learning, team teaching and learning hardening basics, this study surveyed problems and improvements using literature works, questionnaires, observing, and interviews. Through the study on learning space for open education, it has been known that the form of independent classroom fits into one classroom learning and open classroom into small group learning and individual learning, and that the form of open classroom connecting open space with a classroom are more desirable when there is change from large to small group.

The purpose of this study was to examine the characteristics of classroom culture in a toddler class of 2 year olds. Data was collected through 16 sessions of non-participatory observations and teacher interviews of toddlers in H daycare center. Collected data was carefully read and categorized accordingly to fit the theme of this qualitative study. Data analysis yielded four conclusions regarding the toddlers' classroom culture: behavior to advance together as a group, communicating through body language, complete reliance and responses towards the instructor, and a dichotomy between disintegration and integration. The result of this study suggests a need for instructor's proper guidance and establishing an appropriate childcare environment, as well as a reconsideration regarding toddlers as a host of the classroom culture, to increase the understanding of toddler's interactions in classrooms and social trends.

The purpose of this study is to present a block type smart classroom model for comprehensive supply of educational contents, classroom environment and ICT technology in African countries where educational infrastructure is weak. It will provide a contextual solution that integrates learning management, power management, and classroom environment management systems, and will be a convergence model that can optimize economic and non-economic conditions for different African countries. It can be expected to enhance utilization as it is a differentiated model from existing classrooms with a single container, as well as independent research and development centered on services, content, and solutions. Through this integrated research process, we can overcome the spatial and functional limitations appearing in single container classrooms and build a flexible space for advanced e-learning technology. The depth and scope of the follow-up study can be carried by investigating the performance and models that are in line with the educational and infrastructure conditions of the various regions.
