In the study, the effect of flipped classroom approach applied to chemistry I class in a foreign language high school was explored. Flipped classroom was applied to 176 grade 10 students (43 boys and 133 girls) from a foreign language high school located in a metropolitan city for one semester and its instructional effects were studied in terms of cognitive and affective aspects. Before the class, students were provided with guiding worksheets and asked to summarize contents. Within the class, various student-centered activities were adopted. After the flipped classroom for one semester, mid-term and final-term exam scores were analyzed, and students' attitude toward chemistry class and flipped classroom were surveyed. Analysis on the exam scores showed the possibility for positive impact on students' achievement and perceptions on chemistry class including flipped classroom approach. Moreover, some students mentioned flipped classroom was helpful for self-directed learning and meta-cognition. Based on these results, educational implications were discussed.

This study is to clarify the actual conditions of the floor plan of middle and high schools in the rural area. Recently, many middle school and high school are remodeling the buildings and facilities based on the departmentalized classroom system. This study, through analyzing on 4 remodeling cases of middle and high schools in gyeongnam. This article discuses about the basic characteristics of the plan composition and the education programs of 4 schools. This study is showing the variation before and after remodeling and space organization types. The results of this study are summarized as follows; Home-room and home-base should be more faithfully. Various common space is needed to comfortable school life of students. In case of side corridor type plan, moving path is much needed. Sample schools took much more spaces of home base than before. This article discusses about the basic characteristics of the floor plan and the actual condition of the school facilities.

According to the master plan of the Ministry of Education, Science and Technology, departmentalized class system will be extended to all general middle & high schools by 2014 with the exception only of those having less than 6 classes located in small cities in rural areas. Under departmentalized class system, according to class timetable, students need to move from classroom to another classroom and areas where homebases, lounges, media spaces, rest places, and etc. This study has been undertaken to provide architectural data required in planning for student & learning support space for schools operating departmentalized class system, by investigating and analyzing cases in use at schools operating the system in Chungbuk area. As departmentalized class system is increasingly introduced, student & learning support space should be understood newly as spaces indispensable for students.

해마다 실시되고 있는 대학수학능력시험의 듣기 평가시험에 있어서, 고사장 및 지점별 음향 성능에 기인한 레벨 편차와 명료도를 산출하여 학생 선발의 공공성과 객관성을 검토해 보고자 한다. 일반적으로 듣기 평가가 이루어지는 각 고사장은 듣기 평가 실시에 지장이 없는 고등학교 교실로 지정하고 있지만, 균등한 음 환경을 제공해야 하는 시험의 성격에 반해 학교 자체의 방송 시설을 그대로 사용하는 것은 평가의 형평성 및 객관성에 충실하지 못하게 되는 요인이 된다. 따라서, 각 고사장의 확성 시스템에 따른 음성 전달품질과 수험생간의 좌석별 음압 레벨 및 명료도를 평가하였고, 실험 결과 RASTI를 비롯한 음성 및 음절 명료도를 나타내는 파라메터에서 좌석별로 큰 편차가 있는 것으로 분석되었다.

Some blind spots of information were occurring because important information such as school events, employment information, attendance information, and major school schedules were currently communicated through home communication messages only. To address this problem, an e-Board prototype was designed to incorporate P2P-based Internet of Things technology in a wired and wireless network based on a survey of data on smart education based on the Internet of Things. In each classroom, necessary information, such as school events, was received in real time from the classroom and shared in the classroom. They also want to design an e-Board prototype for Internet of Things-based smart education because they are easily accessible to anyone even if they do not know how to use e-Board.

There are many results in which acoustical conditions of a classroom play an important role for studying effects and academic achievement of students. However, there are very few guidelines or design proposals which could make appropriate acoustic environment when classrooms are built or renovated. The present study suggests various design proposals satisfying acoustic standards of classrooms based on theoretical calculation and acoustic field experiments. At first, minimum area of sound absorption was calculated which is required to satisfy the acoustic standard for domestic middle and high schools. Also, room acoustic measurements were carried out in order to investigate the acoustic performance of an existing classroom by changing interior finishing materials on ceiling and rear walls. As a result, it was revealed that reverberation time standard below 0.8 s can be acquired even if there is no sound absorption on ceiling which is a general practice executed in Korea. Specially, it was found that if partial area of ceiling would be treated as reflective with the ratio of sound absorption and reflection as 2:1, almost similar acoustic parameters of $C_{50}$, $D_{50}$, RASTI (Rapid Speech Transmission Index) and higher sound levels could be acquired in comparison with the case of entire sound absorption on ceiling.

Due to a lack of teachers and available classrooms, high school students are not able to take the elective courses of their choice. In order to solve this problem with online instruction, I have used the following methods: First, I conducted a literature study to examine the concepts and models of online instruction. Second, I compared the number of students who took the CSAT subject tests with the number of students who enrolled in optional courses through KEDI's Education Statistics Services. Using the data gathered from this comparison, I could predict the demand for each optional course. Finally, I proposed amending the Elementary and Secondary Education Act; the Enforcement Decree of the Elementary and Secondary Education Act; the General Statement Curriculum of High Schools; and the Guidelines for Recording School through the expert interviews for on-line instruction in order to establish online instruction for high school students.

The purpose of this research is to find out the problem of plan composition by use the school building. The research was performed through the checking of 13 high schools which were built after 1997 in Busan. Followings are the result of the research. Presently, all the schools are divided classes into different levels and teach students, however, it is only limited to English and Mathematics and being carried on mostly for 1st graders. Moreover, although the plan is composed Department System plan which intended to ues new various learning method, schools have changed their plan into Usual with Variation type which is old educational program and renovated a few classes for certain subjects. Due to above reasons, the new kinds of space for Department System plan is used only as a study room by reform or even not used at all. Therefore, improvement of those problems are significant in schools.

본 연구는 전자교육(e-Learning)과 집합교육의 장단점을 상호보완하는 교육형태인 블렌디드 학습(blended learning)이 고등학교 전자계산의 학습성취에 미치는 효과성을 검증하는데 목적이 있다. 이 목적을 달성하고자, 블렌디드 학습모형을 도출하고 이를 토대로 온라인 학습환경을 구축하고, 경기도내 C고등학생 136명을 대상으로 실험집단(68명)과 비교집단(68명)을 구성했다. 두 집단을 대상으로 블렌디드 학습(실험집단)과 전통식 면대면 교실학습(비교집단)을 실시한 결과, 블렌디드 학습에서의 학업성취도가 전통적인 면대면 집합학습보다 더 높은 것으로 나타났다(t=-3.16, p=.0019). 이러한 결과는 블렌디드 학습이 전자계산 학습의 효과성에 긍정적인 결과를 가져다 줄 가능성을 보여 준 것으로, 블렌디드 학습이 기존 전자교육의 단점을 보완해 주는 대안적인 교수 학습방법으로 사용될 수 있음을 시사해 준다.
