This study was conducted to examine my hypothesis that how teacher's teaching style influences emotional and physiological states of students in the secondary school science classroom. Sixty healthy secondary school students were participated in this study and divided into two groups: manipulation and non-manipulation. Each group underwent different styles of teaching on the scientific hypothesis-generating of com starch experiment. Before and after the class, the strength of emotion was measured using adjective emoticon check lists and they extracted their saliva sample for salivary hormone analysis. Here are the results of this study. First, the intensity of positive emotions in the manipulation group was significantly stronger than the one in the non-manipulation group, whereas the intensity of negative emotions in the non-manipulation group was significantly stronger than the one in the manipulation group. Second, the cortisol level, an indicator of stress, was decreased in the manipulation group whereas it was increased in non-manipulation group. Third, the quality of scientific hypotheses which is generated by students during the class had no connection with types of instructions. Fourth, this study found significantly negative correlation between students' emotional intensity of interest and concentration changes of salivary cortisol. Therefore, the different teaching styles have influence upon students' attitude and interest in science.

Elementary education is the most fundamental education phase to cultivate a minimum natural quality for basic people life. Because elementary school is a very important step to be a base of lifelong education, it has to lead students to develop a capability of information utilization and rear the ability of self-leading study. Accordingly the elementary school library must be made and managed to cope with a new environment of education and information, as well as it must be a appropriate facilities for the contents of the 7th course of study : The aim of the 7th course of study is to rear the autonomous and creative Korean who lead the age of globalization and information-oriented. It is an ideal that the school library has a separate building for itself as the general information center but it is not easy to do in our conditions. Accordingly when it Is located in a school house, it has to be at the center within easy access of other related rooms such as a classroom and school house. Therefor making a plan and designing a school building, the school library has to be considered preferentially as a main facilities in order to make a school to accept the future.

The purpose of this study was to examine the current interior conditions of kindergarten and to suggest the interior planning guidelines. Data were collected through questionniare survey including observations and interviews. The sample consisted of 262 kindergarten teachers in Pusav. The data were analyzed by using SPSS-PC. The major findings were as follows: (1) Interior finishes should be chosen based on children's behavioral and developmental characteristics. (2) Considering children's safety and teachers' easy access and observation, classrooms and teachers' room should be located at the first floor, and the public spaces such as playroom and assembly room should be located at the top floor because of noise and circulation problem. (3) The size fo the classroom should be increased based on children's age. (4) The teachers were generally satisfied with location, color, and finishes of each room. There was a significant difference between satisfaction of overall characteristics of rooms and theclasses that teachers are in charge of. (5) Children's developmental characteristics can be an important factor when designing a space for childrev. Even though there were some limitations on this study, the findings can be utilized as a basis for generating interior environmental recommendations for planning a better quality of kindergartev.

In present study, using 1572 low-income families and 266 Head Start teachers from Family and Child Experiences Survey (FACES) in the U.S., we examined the effects of mothers' reading and the characteristics of interaction between teacher-child interaction on 4-and 5-year-olds' cognitive development represented by their verbal and numerical abilities. Frequencies of mothers' reading at home consistently predicted higher scores of children's Peabody Picture Vocabulary Test and Woodcock Johnson Applied Problems. Teachers' sensitivity and permissiveness in their interactions with children in classroom were positively related to children's verbal abilities and teachers' sensitivity predicted better numerical abilities of children after controlling for mothers' reading and the characteristics of family and teacher. The findings shed light on the contributions of teacher behaviors and familial factors to children's cognitive development calling for attention to the need for parent education on cognitively stimulating family environments and continuing education for early childhood teachers focusing on quality interactions with young children.

The purpose of this study is to investigate the effect of real-time remote video instruction using zoom on learners' English reading achievement. The study also sought to identify the efficiency of zoom video lectures and consider supplementing them by surveying learners' opinions and satisfaction regarding zoom video lectures. To this end, control and experimental groups were set up, and two achievement tests and a questionnaire were conducted. The study's results demonstrated that zoom video lectures have a positive effect on learners' English reading achievement. The questionnaire found that learners are satisfied with zoom video lectures for the following reasons: 'increased interest in and motivation towards learning', 'self-directed learning', 'active interaction', 'ease of access', 'ease of information retrieval'. At the same time, the questionnaire also found that some learners are dissatisfied with zoom video lectures due to 'mechanical errors or defects', 'poor audio quality', and 'the need to add customized functions for efficient classes'. In practice, zoom video lectures must be supplemented with automatic attendance processing, convenient data upload and download, and more efficient video screen management. Given the recent increase in online classes, we, as instructors, must develop teaching activities and/or strategies for video lectures that can encourage active participation by learners.

Since the 7th educational renovation was established, ICT has emerged as an indispensable tool for teaching a variety of subjects in technical high schools. This paper develops the model for explaining the factors affecting the use of web contents as a mode for studying Electronic subject. Based on data collected from a questionnaire survey from the students who studied the Electronic subject using web contents, a following conclusion is provided: the perceived usefulness, ease of use and the playfulness significantly affect the level of satisfaction, but the design of contents, image, quality, attitude as well as self-efficacy only indirectly affect the satisfaction level. This result might provide the useful guidelines for designing the web-contents for technical high school students.

Most of education sites which are related to practical computer lecture are almost teaming and testing based on character-contents. In this thesis, commercial high school needs the use of new application programs which appear quickly. So as teacher and students can contact with each other in classroom, we implemented self-learning which has text, visual and auditory function with the use of animation technology. Not only quantity testing which has been used for the purpose of selection and arrangement, but also we designed and implemented quality testing which consider the level and individuality of student.

Teaching orientations represent teachers' general way of conceptualizing their teaching. The orientations are regarded as a very important factor in developing teachers' pedagogical content knowledge because they often guide their instructional decisions such as the selection of contents and teaching strategies, the use of curricula materials, and the evaluation of learning. Thus, understanding teachers' orientations can provide meaningful suggestions to understand their instructional approaches and furthermore to enhance the quality of engineering education in college. The research question for this present study was what kinds of teaching orientations engineering professors possessed in teaching engineering courses and how the orientations were represented in their teaching. Six engineering professors, particularly interested in instructional approaches, participated in the research. The data sources included in-depth interviews with individual professors, classroom observations with field notes, and related documents. In results, four teaching orientations toward engineering courses were identified: 1) expert knowledge in engineering, 2) engineering practice, 3) social practice, and 4) interdisciplinary design. Individual professors had between one to three different teaching orientations. Even though the professors had similar orientations but their instructional strategies somewhat varied based on the disciplines.

Modern people spend most of time at indoor space, such as office or classroom. Especially, occupants are exposed to the airtight indoor air quality (IAQ) for a long time, At present, many studies on the air-conditioning systems are more focused on the individual thermal comfort than the thermal efficiency due to increase of the concern of health. There are several factors which are influenced thermal comfort, such as temperature, humidity, convection and air movement, etc. Also, the individual factor, such as age, gender, Physical constitution and habit, should be considered. The 4-way cassette type air conditioner is known to bring out better performance about thermal comfort than the traditional one. This study is performed on the higher ceiling environment than the common buildings or classrooms. Also, this study analyzed on the Indoor thermal comfort by diffusing direction of 4-way cassette air conditioner with various discharge angles, $45^{\circ},\;50^{\circ},\;55^{\circ}$ and $60^{\circ}$. Using a commercial code, FLUENT, three-dimensional transient air thermal flow fields are calculated with appropriate wall boundary conditions and standard $k-{\epsilon}$ turbulence model. Results of velocity and temperature distributions are graphically depicted with various discharge angles.
