The purpose of this study was to propose for efficient selection with observation and nomination system and efficient operation of Convergence Science class in a Science Institute for Gifted Youth attached in university. For this purpose, we analyzed the result of entrance exam with observation and nomination system, and the correlation between enterance exam score and achievement to perform at the Convergence Science class. As a result, despite observation and nomination system is highly dependent on observers and recommenders, they have very different perspectives each other. In addition it was founded that selection and education process after admission is inconsistent.

The purpose of this research is to investigate how an elementary English class is presented in terms of communicative properties using COLT and TALOS because previous studies mainly used COLT. A lack of TALOS has shown on the previous studies. Also, this study takes a close look into whether the English class is communicative or not communicative since previous studies criticized in that elementary English classes are not communicative. For the purposes of this research, COLT part B and TALOS low-inference were used to analyze one elementary English class which had won the grand prize at English class contest. The result of this study revealed that the class is communicative in terms of high quantity and quality of students utterances, high ratio of students' discourse initiation, students' unpredictable information giving utterances and extension of utterances. Findings from this study revealed the good elementary English class characteristics of this class: students' participation, focus on affective atmosphere, students-directed activities, and unconscious internalization of target expressions through repetition.

The purpose of this study was to investigate infants' individual attempts at interaction with their teachers in the two-year-old class curriculum of a child care center. To achieve this aim, this study analyzed both the types of interactions that infants attempted with their teachers, as well as the underlying message contained in infants' attempts at of interacting. This study used the complete participation observation methodology following an ethnographic approach, a research method which can help us see the whole picture by tracing the main causes and connections. The participants in this study were 13 infants and their teachers in 2 two-year-old classes (Hope and Love) of the Vision Child Care Center located in G city. The researcher, who was also a Hope-class teacher, ad as an observer, and the Love-class teacher acted as an assistant observer. Participant observation was made everyday except the days when field trips and group activities wewe planned, from october 2009 to January 2010. A variety of methods were used to collect materials, such as participant observation, in-depth interviews and collection of documents.

Environmental Literacy is needed to establish a sustainable society and can be very well developed through Outdoor Environmental Education(OEE). However, establishing OEE in Korea is a very difficult. Thus, it is very important to find out which factors influence the sustainability of OEE. The purpose of this study is to identify those factors. Participatory observation research and some interviews were used in "The Whale Class" of the University of Georgia in the United States. Major findings and recommendations were as follows: (1) OEEs give participants good experiences about the environment; (2) Program operators of OEEs are enthusiastic about education and environmental conservation; (3) Good educational practices such as cooperative education and participation in conversation foster learning; (4) Good organizations with guest lectures from various environmental fields would be beneficial; (5) Public information about environmental programs would be helpful; (6) Administrative support for those organizations connected to environmental programs would be useful; and (7) OEE provide reflection activities to foster Environmental Literacy.

This study introduces the Classroom Assessment Scoring System (CLASS) and explores the characteristics of CLASS for observing classroom. The CLASS is a standardized observation instrument that was largely developed for use in the USA. The CLASS attempts to provide a conceptual framework for categorizing classroom interactions and consists of three broad domains of quality (emotional supports, classroom organization, instructional supports). We simulated this method to the elementary school classes. The professional-teacher makes the best use of student's initiation behaviors, and the novice teacher focused on the leading the contents of subject. The novice teacher tyr to make more positive climate and to present more frequent feedback to students than professional teacher's classroom. The professional teacher would like to reveal the student's opinions, questions and subtle emotional state. The CLASS can be used to collect data on a wide range of specific aspects of the teaching and learning process at any given time.

The purpose of this study is to identify how primary students make decision in an anomalous situation of discrepancy between the observation result and their prior knowledge and what is the relationship between their decision and views on science. In this study, the researchers have observed a science class of fifth graders for two months and collected qualitative data such as field note, audio transcript, video-recording, photo and interviews. It is shown that participants experienced three types of subjective observation as listed: expectation-related, theory-dependent and dilemmatic observation. The questionnaire of the students to the views on science reveals that most of them thought highly of empiricism and utility of science. With this result, it is found that they took into account the limitation and provision of experiments while making judgment in an anomalous situation. That is to say, their assessment of experiments and observation is crucial in judgment in the situation that their observation is incompatible with their prior knowledge. The researchers conclude that their views on science may influence their observation and suggest the ways to promote students' ability linked to observation.

During a field survey of indigenous Korean ciliates, we collected 21 unrecorded species from aquatic (freshwater and brackish water [salinity about 1.0‰] samples) and terrestrial(moss and soil samples) habitats. The morphology of these species was studied based on live observation, protargol, silver carbonate and silver nitrate impregnation, and scanning electron microscope. These species belong to seven classes as follows: 1) class Heterotrichea - Blepharisma seculum; 2) class Spirotrichea - Birojimia terricola, Bistichella variabilis, Deviata bacilliformis, Oxytricha paragranulifera, Parabistichella cf. variabilis, Steinia sphagnicola, Stichotricha aculeata, Stylonychia cf. notophora, and Tetmemena bifaria minima; 3) class Armophorea - Metopus es; 4) class Litostomatea - Acropisthium mutabile, Pseudomonilicaryon japonicum, and Rimaleptus alpinus; 5) class Phyllopharyngea - Podophrya bivacuolata; 6) class Nassophorea - Drepanomonas pauciciliata; and 7) class Oligohymenophorea - Dexiostoma campylum, Frontonia atra, Histiobalantium natans viridis, Opisthonecta minima, and Tetrahymena rostrata. Here, we provide a brief diagnosis and remark for each species.

This study examined in depth what teachers experience in a practical problem-based home economics class. This study established the research question, "What do teachers experience in the practical problem-based home economics class?" and selected three teacher participants who had steadily performed a practical problem-based home economics class to directly observe classes and conducted intensive interviews with the class performing teachers. The three research participants performed the practical problem-based class as a method of practicing their educational beliefs and based on a problem consciousness that textbook centered classes focusing on concepts cannot manage. They also tried to make efforts to reconstruct the textbook centered with practical problems to promote the critical thinking abilities of students. In practicing the practical problem-based class, the research participants recognized that it was important to show the present problems in reality to the students, teach broad value concepts, and establish rapport with students. They tried to make class content correspond to class evaluation. They felt awarded in how they influenced the development of students and the perception of home economics subjects in a positive way as well as experienced various actual difficulties in performing the practical problem-based class. The three research participants examined themselves through the agony and reflection of the class, and integrated the class with daily activities by applying problem solving methods of practical problem-based classes to their lives.

The purpose of this study is to examine the differences of perceptions of teachers and students regarding teaching skills. For the analysis, data was collected by ICALT(International Comparative Analysis of Learning and Teaching) class observation tool and students survey called My Teacher Questionnaire. a student survey. The data of teachers and students can be compared because as the two tools have seven common domains(Safe and stimulating learning climate, Efficient organization, Clear and structured instructions, Intensive and activating teaching, Adjusting instructions and learner processing to inter-learner differences, Teaching learning strategies, Learner engagement). In 2016, in Daejeon, Chungbuk and Chungnam. trained teachers collected data from 106 classes, and 2,866 students responded the survey. The reliability and validity of the two tools, class observation and MTQ(My Teacher Questionnaire) are proven to be satisfactory for use in Korean schools. Students perception on teaching was high, particularly when students are in lower grades and learning major subjects like English, Korean, and math. The domain of higher teaching skills, male students show higher perceptions while female students reported higher perceptions on lower-level teaching skill domains. To compare the perceptions of teachers and students, the predictive reliability of students engagement against teaching skill domains was used. Teachers showed higher predictive reliability on lower teaching skill domains while students showed higher predictive reliability on higher teaching skill domains. It is recommended for further study to develop a professional development model using a teacher class observation tool and the My Teacher Questionnaire for pre-service teachers and school teachers.

The purpose of this paper is to compare and analyze the two different teaching methods of elementary mathematics in the traditional method and in the constructive view. To do so, the actual class in the constructive view has been made for about four months using a class of 45 students in the second grade of an elementary school. After the class was finished, we collected diverse data from the class, such as the responses from the children(self-evaluation, mathematics diary, observation by the investigator, daily report), class evaluation report by other teacher and so on. The results of this research are as follows: First, the traditional class reaches at the goal of learning in a unit time because the class is guided by the teacher but the class in the constructive view is a little flexible because it is contextual. Second, in the constructive process of mathematical knowledge we knew that small group activities or discussion without intervention of teacher was often ended in exhaustive argument without arriving at valid social consensus. Third, the attitude in mathematics was changed from the passive one to the self-regulated ones. Fourth, the class in the constructive view could extend not only the ability of mathematical communication but also the ability of self-directed learning of children. Fifth, it was a considerable change the role of teacher, that is, guide of instruction instead of unique specialist in the classroom. Sixth, finally, the evaluation was made after finishing a unit class in the traditional instruction but it was integrated in a class in a constructive view.
