본 연구는 다수준 포함 교수법(multi-level instruction)을 적용한 초등과학 프로그램을 개발하고, 이를 적용한 수업 과정에서 나타나는 학생들 간의 언어적 상호작용을 분석한 것이다. 이러한 연구 목적을 달성하기 위하여 경기도 H시의 B초등학교 5학년27명을 대상으로 이질적인 4명의 학생으로 소집단을 구성하였고, 매 차시마다 2개 소집단의 수업 과정을 녹화하였다. 5학년 2학기”1. 우리의 몸”단원을 대상으로 다수준 포함 교수법을 적용한 초등과학 프로그램을 개발하였다. 언어적 상호작용은 크게 인지적 영역과 정의적 영역 두 가지 측면으로 분석하였다. 인지적 영역은 응답, 질문, 의견제시, 의견받기로 정의적영역은 행동참여, 분위기 조절로 세분화하여 분석하였다. 다수준 포함 교수법을 적용한 초등과학 프로그램에서 학생들의 언어적 상호작용 분석 결과는 다음과 같다. 첫째, 인지적 영역과 관련된 언어적 상호작용이 정의적 영역과 관련된 상호작용에 비해 많이 일어났다. 둘째, 인지적 영역에서는 중위수준 아동의 언어적 상호작용 빈도가 가장 높았고, 정의적 영역에서는 상위수준 아동의 빈도가 가장 높았다. 인지적, 정의적 영역에서 모두 하위수준 아동의 빈도가 가장 낮게 나타났다. 셋째, 인지적, 정의적 영역에서 상위-중위수준 아동 사이에는 언어적 상호작용의 빈도에 차이가 없었다. 그리고 상위-하위수준 아동보다 중위-하위수준 아동에게서 유의하게 차이가 있는 상호작용유형이 더 많았다. 중위-하위수준 아동은 행동 참여를 제외한 모든 영역에서 유의한 차이가 있었다. 넷째, 시간이 지날수록 전반적으로 아동들의 언어적 상호작용의 빈도가 증가하고 있었다. 또한 성취수준에관계없이 활발한 상호작용이 일어나고 있음을 알 수있었다. 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 medianlow level children`s verbal interaction than high-median level children`s verbal interaction.

이 연구는 COVID-19로 인하여 온라인과 대면 수업이 병행하여 이루어짐에 따라 초등교사가 과학 수업에서 겪는 어려움이 무엇인지 알아보고자 한 것으로, 초등교사 66명을 대상으로 설문을 진행하였다. 그 결과, ‘수업 전’ 활동에서 수업 설계가 가장 어려운 영역은 온라인 수업에서 운동과 에너지, 대면 수업에서 생명 영역으로 나타났다. 모두 실험 활동 자체가 이루어지지 못함에서 비롯된 어려움이었다. ‘수업 중’ 활동에서 교수 학습 방법 중 가장 수행하기 어려운 것은 온라인, 대면 수업에서 모두 실험 활동으로 나타났다. 교사는 실험 활동 자체를 진행하지 못하는 것에 대한 큰 아쉬움을 나타냈다. 교수 학습 방법 외의 어려운 점은 다양한 활동의 제약으로 나타났다. 온라인 수업에서는 교사의 일방적인 강의식 수업만 이루어지고 즉각적인 피드백이 이루어지지 않는 것, 대면 수업에서는 방역수칙에 따라, 활발한 상호작용이 이루어지지 못하는 것에 대해 안타까움을 나타냈다. ‘수업 후’ 활동에서는 학생마다 이해도가 다르고 즉각적인 피드백이 어려운 것으로 나타났다. COVID-19 이후 우리는 본격적인 온라인 교육 시대를 맞이하였다. 누구도 처음 겪는 이 상황에서 초등교사는 과학수업에서 위와 같은 어려움을 겪고 있었다. 이를 해결하기 위해서는 현장의 목소리가 적극적으로 반영된, 국가적인 차원에서의 행정적·재정적 지원이 다각도로 이루어지기를 기대한다. This study examines the difficulties faced by elementary school teachers because online and offline science classes were conducted concurrently due to the current COVID-19 pandemic. Sixty-six elementary school teachers participated in a survey conducted for the current study. The results show that the most difficult areas for class design in the “before class” activities were the exercise and energy domains for online classes, and the life domain for offline classes. These difficulties arose from the inability to conduct experimental activities. Among the teaching and learning methods included in the “in class” activity, the most difficult task to perform was experimental activities in both online and offline classes. The teachers expressed significant regret for being unable to proceed with the experiment activity. In addition to the teaching and learning method, the limitation of various activities was yet another difficulty. In online classes, only teachers unilateral lecture-style classes were conducted, thus immediate feedback could not be provided. Moreover, in the offline class, they expressed regret for being unable to engage in active interactions because they are required to observe the quarantine rules. During the after class activity, the teacher noted that each student had a different understanding and it is difficult to derive immediate feedback. In this situation that the current population has no prior experience for, the elementary school teacher faced the aforementioned difficulties while conducting a science class. Since the onset of the COVID-19 pandemic, we have entered a full-fledged online education era. To overcome these difficulties, administrative and financial support reflecting the opinions of the teachers at the national level must be provided through various methods.

As development density increases due to an increase in demand for apartment houses according to economic growth, a trend toward high density·high rise apartment occurs. Accordingly, a bad influence is exerted on residential environment. Besides, the actual condition is that microclimate in urban space is getting worse due to an increase in artificial structure coverage ratio and imprudent apartment house block planning. For the improvement of urban microclimate and comfortable residential environment, a design that considers sunlight environment and outdoor thermal environment is needed in planning an apartment complex. And quantitative review and relevant baseline data accumulation is required. We quantitatively evaluated and analyzed an effect produced on the sunlight environment and outdoor thermal environment according to the change of floor area ratio and building coverage ratio, a main factor of building density in apartment houses. Sunlight environment is more sensitively affected by the change of building coverage ratio than that of floor area ratio under the same conditions of distance between buildings. The percentage of apartments having insufficient solar access decreased by an average of 2.1% according to the increase of floor area ratio. On the other hand, in case the building coverage ratio increased, it increased by an average of 25.2%. With regard to outdoor thermal environment, as floor area ratio increases, average building surface temperature decreases by 1.6~2.0% and average MRT decreases by 3.2~4.5%. Besides, it is possible to find that a daily variation in HIP becomes larger according to the increase of floor area ratio than according to the change of building coverage ratio. It is thought that the reason is that sunlight environment and outdoor thermal comfort in summer is largely affected by sun shade in comparison, and in case of HIP, the effect of artificial structure coverage ratio such as roof slab area is more dominant. It is believed that building density needs to be planned in consideration of comfortable residential environment in planning an apartment complex. And it is thought that a plan to which an environment-friendly technique is applied should be made according to whether floor area ratio and building coverage ratio is applied.

The concentration of population due to urbanization has intensified and the quality of residential environment has also deteriorated as a result of indiscriminate high-rise and high-density housing development caused by the mass supply of apartments. Although policies have been established to secure sunlight for the improvement of the quality of urban residential environment, there is a concern that they will worsen the outdoor thermal environments. This study aims to investigate an optimal apartment complex plan in consideration ofthe combination of sunlight and outdoor thermal environments. Sunlight environment analysis and outdoor thermal environment simulation were conducted in a case to which the design of experiment was applied. In addition, eco-friendly technical elements were introduced to determine the possibility of securing a comfortable residential environment.

Economic growth and population concentration have led to rapid urbanization. This phenomenon of urbanization has resulted in deteriorating climate patterns as building-influenced urban microclimates, such as heat islands, develop and cause, directly or indirectly, loss of life and economic activity. In this study, apartment housing block, which comprise a large portion of the buildings in a city, were targeted for a quantitative analysis on the effect of building skin and surface cover of outdoor space on the outdoor thermal environment. The design elements and materials for building skins and surface cover of outdoor space were selected, and a case study was conducted by subjecting the selected materials to a simulated outdoor thermal environment. It was shown that while a change in the component materials of a roof surface plan affected its temperature, it did not have a direct impact on the MRT and HIP evaluation indexes. The component material change that resulted in the largest reduction in the roof surface temperature was the addition of grass. It was verified that a higher thermal insulation capacity in the outer wall insulation plan worsened the outdoor thermal environment. However, at 0.15 W/㎡·K, the temperature increase rate in the MRT and HIP evaluation indexes was shown to decrease. An increase in the window wall ratio (WWR) in the doors and windows plan improved the outdoor thermal environment. In the surface cover plan for outdoor space, greening resulted in the largest reduction rate of the HIP and MRT evaluation indexes, and was not observed to affect the surface temperature of buildings.

In this study, this researcher selected D/H ratio and azimuth among the allocation factors of the apartment housing. This study has the purpose of establishing the optimum plan for the apartment housing with the consideration of environmental factor. The optimum D/H ratio and azimuth through the analysis of environment of solar and thermal is 1.0H and S, SE60°, and it is effective on the reduction of the building energy and improvement of the quality of interior environment when planning the complex. If we plan the allocation by applying 0.8H of D/H ratio, it helps to improve the thermal environment by using the natural covering to the ground and ecological skin to the building.
