The cultivation of creative convergence talent has become more important than ever, the Korean curriculum has also undergone many changes, aiming for convergence and integrated education. In addition to these changes in science and curriculum, we examined the changes in perception and Professionalism(PCK) of integrated science education of science teachers over the past decade. For this study, 359 elementary and secondary science teachers in 2008, when the 2007 revised curriculum was applied, and 360 elementary and secondary science teachers in 2018, when the 2015 revised curriculum was applied, were examined for 10 years of changes in perceptions and PCK of integrated science education. The conclusions from the analysis were as follows. First, in 2018, elementary and secondary science teachers were found to have a statistically significant increase in awareness of integrated science education. Nevertheless, cognition was found to be 'normal'. Second, teachers' perception of the necessity of improving the professionalism of teachers, providing teaching and learning materials, reducing the contents of learning, reducing the number of students and securing flexible timetables, and raising the perception of integrated science education for students and parents as a condition for the success of integrated science education, was analyzed to be significantly higher in 2018. Third, the results of PCK survey through self-diagnosis, teachers' PCK on integrated science education, such as competence to secure curriculum contents knowledge, comprehension of curriculum and class composition related to integrated science education, teaching strategy for integrated, creation of teaching and learning environment for integrated teaching, efforts to improve administrative constraints and the professionalism of integrated science education, was significantly higher than it was ten years ago. Therefore, the recent emphasis on convergence education has increased the experience of applying convergence classes in the field of education, and it was seen as a result of the continuous efforts of science teachers to meet the changes in the education paradigm.

This study was conducted on 115 students from 4 classes of 2nd year intensive courses at B University of Education. Elementary preservice teachers were surveyed on what teaching methods they were aware of regarding the subject of elementary science astronomy. Recognition data of 80 people from whom the questionnaire was collected were analyzed. For this study, a 5-day survey was conducted. Elementary preservice teachers complained of difficulties in teaching methods in the astronomy area among various areas of the science department. The purpose of this study was to find out what difficulties elementary preservice teachers have in teaching elementary science astronomy topics, and to find more efficient teaching methods for teaching astronomy topics. The topic of the survey was set by discussing with the preparatory elementary teachers about what kind of survey to use in teaching the subject of elementary science astronomy. There are many topics for elementary science astronomy, but two questionnaires were prepared focusing on the unit on the earth and the moon. 'What does the earth look like?' in Unit 4 (1/10) of the 3rd year, 1st semester In Unit 2 (1/11) of the 1st semester of the 6th grade, it was set as 'What does the moon look like?'. Candidly describe how to teach the subject of astronomy to elementary school students by mobilizing all the background knowledge of preparatory elementary teachers. The results of these surveys were visualized and displayed using Netminer as a language analysis method, and the contents of the responses to the actual surveys by pre-service elementary school teachers were described and interpreted. Based on these results, preparatory elementary teachers tried to suggest a more efficient teaching method for the subject of elementary science astronomy. In addition, basic procedures and methods for lecturing on the subject of elementary science astronomy were presented. A more efficient teaching method for teaching elementary science astronomy subjects to pre-service elementary teachers was suggested.

For effective teaching-learning activities for students with diverse talents in science high schools, it is important for teachers to understand students' individual differences in perceiving and processing information in the natural world, depending on the students' various talents and subject characteristics. The purpose of this study is to examine the students' cognition of chemistry in science high school through correlations and factor analysis of mathematics/science achievement. In addition, this study attempted to examine the cognition of chemistry subject according to R&E classes. The main participants of the study were freshmen of G science high school (296 students) who entered after three times of curriculum reforms and new admission processes and the students in two other science high schools in Gyeongnam and Ulsan were included. The correlation and factor analysis were conducted by exploratory factor analysis by IBM SPSS Statistics 25 programs. The results of this study were as follows: First, in the correlation analysis between mathematics and science achievement, it was confirmed that the Pearson's coefficient of chemistry showed higher positive correlation coefficient than that of other science subjects. Second, in the factor analysis of mathematics and science achievements, it was found that the factor indicators were divided into two factors as logical-mathematical (mathematics and physics) and naturalistic (life science and earth science). Third, in the factor analysis, it was confirmed that the chemistry is recognized as the subject that requires both logical-mathematical and naturalistic intelligence. Finally, it was confirmed that students' cognitions of chemistry subject were found to differ according to the R&E classes. In other words, the participants of R&E chemistry class, unlike other students, were found to recognize chemistry as the subject that logical-mathematical intelligence is needed.

The purpose of this study is to investigate the characteristics of 'best practire' in mathematics and suggest some solutions to several problems emerging in mathematics classes of secondary schools. The study was carried out by using qualitative research methods such as class observations and in-depth interviews with six teachers. Based on the collected data, we could sort out the major patterns which characterize 'the good mathematics teaching' at schools in Korea. The common characteristics of best practice in mathematics are drawn out from the six cases. The common characteristics include revising the curriculum and text books, realistic mathematics education, using ICT and meta-cognition, introduction with motivation and interest, performance assessment and managing differentiated small group. Results implied that six teachers used a variety of instructional methods and strategies which is related with the common characteristics of good mathematics teaching. Also these teachers not only improved their own classroom practices but also participated in various professional community of mathematics education and shared their practical knowledge. In conclusion assorted efforts from the government and the school principals as well as the teachers are prerequisite for practicing and spreading good mathematics teaching across the classrooms.

I made a careful study of affective variables in foreign language learning Affective variables have not been adequately investigated in the study of second language acquisition. Egoism and inhibition are two egocentric factors which play important roles in foreign language learning. Three sociocultural variables. cultural factors, introversion / extroversion, and aggression may be keys to understanding the social nature of second language learning. And the emerging of cognition and affect in "cognitive styles", which vary within and among individuals, might account for varying degree of success in learning a second language. In the process of learning English. the students new to foreign language come to face the language barrier. though they express the deep interest and feel excited at the beginning stage. Of course, the several reasons can explain this fact. but more specially they can be explained in terms of such personal affective factors as age, aptitude, personality, and first of all, motivation. Also the socicultural factors between language and culture can be considered to the learner's aptitude toward the language. Affective factors of students are involved in personality. and personality and affective factors affect English learning. Affective variables of students affect the will to take part in English learning, and the rate of participation in English learning affect the fluency. If students feel inconvenience in English class, it is rarely that they run a risk. Students who do not run a risk in English class are short of spontaneous participation Consequently, it may have negative influence on the accuracy and the fluency of English. Therefore, teachers must be more influential in motivating students and specially attentive so that the students may not make the negative and inhibitive language learning attitude.

The purpose of this study is to carry out the research of the satisfaction level of consumers (students and teachers) and managerial characteristics for model classes of the subject classroom system and to draw the effective plan of the system. The conclusions are as follows First, the biggest advantage of the system is to fulfill the educational goal according to an individual level and ability of each student while the biggest disadvantage is the inconvenience of students to change their classrooms for each specific class. Second, it is necessary to rearrange the classrooms according to the applied subjects from the aspect of curriculum management since the time frame is not convenient for recess. English and mathematics are required preferentially as applied subjects, however Korean (as a national language) and science are needed to be taught with level-differentiated classes, too. The ideal size of classes is most likely 20-25 students according to the result of research. Lastly, the space of environment is another requirement to secure smooth flow of students' movements and extra space for technical devices used for information research. The above analysis indicates the necessity of supplementation in space planning for further implementation of subject classroom system in secondary school.

The present study investigated perception of social authority by children and adolescents removed from illegally built shacks 181 children and adolescents from illegally built shacks and 200 comparative respondants of middle socioeconomic status were investigated. Perception of the social authority figures was classified by 5 categories(self, family member, neighbor, teacher and peer. social authority, collective member) in terms of contactable possibility and psychological distance. The data were analyzed by Hest. The results showed that (1) compared with their middle class peers(M group) children and adolescents from illegally built shacks(S group) perceived social authority figures positively, while they perceived their own family members less favorably. (2) The S group regarded their teachers as more valuable and able than M group. (3) The S group perceived social authority figures, i. e., statemen. polices. national assembly members. public servants and enterprisers, less favorably than their family members. (4) There were main effects of the age and sex variables of respondants. (5) There was an interaction effects between the age. sex and SES variables and was also interation effect between age. sex and task variables in cognition for the social authority figures. There was also an interaction effect between age and SES variables in perception for the personal traits of the social authority figures.

The purpose of this paper is to provide two levels of conceptualization of a category such as an absolute category in semantic level and a relative category in pragmatic level on the basis of Aristotelian category theory and prototype category theory. I do not intend to criticize classical category theory and prototype category theory but to show that these two types of category are applied to the different world. Aristotelian categorization is an absolute category because it is based on the possible world called the meta-world and it has an absolute truth value. The members of an absolute category is presented as a set. There is a clear boundary between members and non-members because they are distinguished by the absolute criteria An absolute category is semantic conceptualization. This absolute category is changed into a relative category when it is applied in the real world. A relative category which corresponds to a prototype category is based on the real world called the object world and it has a relative truth value. Here individuals are categorized by the cognition and perception of human beings. A relative category is pragmatic conceptualization. In conclusion, while classical categories which are called absolute categories represent sentence meaning, prototype categories which are called relative categories represent utterance meaning.

According to Kant, time is integral to all human cognitive experiences. Human beings perceive things in the frame of time. Phenomena are perceived in successive way or in coexistent way. In this paper, I argue that the perspective of temporality and atemporality can be a framework to consider the issues of teaching and understanding of mathematical knowledge. Significance of temporal inquiry of atemporal phenomena is discussed with examples of mathematical expressions and geometric figures. Significance of atemporal inquiry of temporal phenomena is also discussed with examples of the sum of natural numbers, geometric pattern, and the probability of two events. Teachers should understand the potential of mathematical tasks from the perspective of temporality and atemporality and provide students with opportunities to inquire temporal phenomena atemporally and atemporal phenomena temporally.
