In this study, science teachers' perception and attitude toward nanotechnology are examined through questionnaires gathered from 134 secondary science teachers. As a result, the study shows that science teachers have high perceptiveness. However, they do not understand specific information on nanotechnology correctly. Science teachers have positive attitudes toward nanotechnology and they have perceived risks of nanotechnology as well as benefits of nanotechnology. Science teachers show positive attitudes toward the application of nanotechnology, whereas they show negative attitudes toward personal information chip and nano-taste enhancer. Science teachers are exposed to nanotechnology via various sources such as TV and internet, whereas teachers rarely get information on nanotechnology-related concepts in textbooks and teaching resources. Science teachers have perceived many textbooks do not introduce enough nanotechnology-related concepts. Many teachers try to explain the nanotechnology when textbooks include nanotechnology-related concepts, whereas quite a few of teachers do not introduce the nanotechnology-related concepts in class.

The purpose of this study was to determine if teachers' perception of professionalism, teaching intentions, and the quality of teacher-child interactions differed by teachers' education and career and how those variables were associated with one another. It was conducted in 50 teachers who were in charge of two- to five-year-olds at 22 national/public, private, and employer-supported childcare centers in Seoul and Gyeonggi Province. Arnett's (1989) Caregiver Interaction Scale (CIS) translated by Choi and Shin (2015) was used to measure the quality of teacher-child interactions, and the Current Status and Self-Desire for Professional Competence scale developed by Wang (2005) and translated and revised by Jeong (2016) was used to measure a teacher's perception of professionalism. The Teaching Intention Scale (TIS) developed by Wilcox-Herzog and Ward (2004) and translated and revised by the researcher was used to measure teaching intentions. The researcher and the research assistant personally visited the centers to observe the teachers for the quality of teacher-child interactions and a questionnaire for teachers was used to determine a teacher's perception of professionalism and teaching intentions. For data analysis, t-test and Pearson's product-moment correlation analysis were performed on the basis of the questions. The results of this study can be summarized as follows: First, the quality of teacher-child interactions differed insignificantly by education or career. Second, teacher's perception of professionalism differed significantly by teachers' career but differed insignificantly by education: the longer career, the better perception of professionalism. Third, teaching intentions differed insignificantly by education or career. Fourth, teachers with better perception of professionalism showed higher quality of teacher-child interaction. Fifth, The higher level of teaching intentions teachers showed the more sensitive interactions they made with children.

This study attempts to extract the necessary criteria as a secondary school home economics teacher through the factor analysis, and to analysis the teacher's and student's perceptions for the requirement criteria of home economics teacher(RCHET) thereof to confirm the necessary criteria as a secondary school home economics teachers. This research was based on the requirement criteria of home economics teacher developed by Korea Institute for Curriculum and Evaluation(KICE) Korean Home Economics Education Association(2008)(KHEEA) collected from secondary, upper secondary school home economics teachers and students in Jeollabuk-do. RCHET encompasses the six areas : (l)'Expert of lesson related to evaluation' (2)'Efficient manager of diverse materials for study', (3)'Student advisor equipped with a teaching sense of duty and sound humanity', (4)'Curriculum expert equipped with a expertise knowledge', (5)'A fair and democratic schoolroom environment promoter'. (6)'Career path counselling expert understanding student's characteristics and environments'. Through the factor analysis, six RCHET factors are more important to teachers than students. According to importance perception for RCHET, home economics teachers' qualification for minor second subject and participation of training program showed similar differences statistically in all RCHET factors. Thus, effort for expertise improvement of teacher had important influence on expertise improvement of teacher. As a result of examining the differences from importance evaluation for RCHET, similar differences from frequence of home project, preference of home economics teacher, manual training and home economics score, interest of home economics showed statistically.

Activity materials in textbook could facilitate students' oriented self-help learning. The purpose of this paper is to find out characteristics of activity materials in the housing area of middle school Technology and Home Economics and teacher's perception of them. The data were collected from 253 middle school teachers who had ever taught the housing unit in any of 6 textbooks. The results showed that the number of activity materials were differed by the characteristics of the materials such as type of materials, feature of non sentence materials, and type of activity, depend on authors as well as textbooks. In general, teachers interests in the materials were higher than those of students even the trends of the interests were the same. Adequacy of activity contents and related knowledge of teachers were higher than adequacy of level. Teachers thought time and extra search beyond class were barrier to full the interests of students. Further research is suggested to find out whether higher interests in the materials are related to the higher activating rate of them.

This study investigated elementary preservice teachers' conceptions of a generating line, an ambiguous concept in school mathematics. The preservice teachers' conceptions of a generating line can be classified into four types: (a) only cones have generating lines, (b) only cones and cylinders have generating lines, (c) solids of revolution have generating lines, (d) straight lines on the lateral surface are generating lines. 22.1% of all preservice teachers believed that only cones have generating lines, and most of them followed the definition of a generating line presented in elementary mathematics textbooks. The conception that only cones and cylinders have generating lines was the least investigated. However, since there were instances where generating lines were defined with the use of a director curve, it became important to explore topics more thoroughly, such as generating lines of a truncated cone. 27.9% of all preservice teachers believed that solids of revolution have generating lines. This conception was marked by differing opinions on whether spheres also have generating lines. The conception that straight lines on the lateral surface are generating lines was the most frequently investigated. This conception differs from the traditional view in school mathematics because it suggests using a director curve to define generating lines. Based on these analysis results, the researcher developed specific teaching methods that considered both subject matter knowledge and pedagogical content knowledge for preservice teachers. In addition, the researcher proposed a consensus definition of a generating line in mathematics education.

Recognizing the necessity of content-centered teacher professional development programs in a rapidly changing educational environments, this study analyzed the contents of teacher professional development programs in terms of teachers' participation by program contents and teachers' perception of the necessity and the effectiveness of such program contents. Employing Teaching and Learning International Survey(TALIS), this study analyzed the perception of 4,000 Korean secondary school teachers. The results showed that the programs with the highest teacher participation were mainly subject-centered while the teacher participation rates on the newly required contents such as ICT, intercultural counseling, school management and administration, and new job skills were low. Besides, when teachers were asked to identify the content areas where teacher professional developments are needed, the level of teachers' perception of the programs with low participation rates was accordingly low. Lastly, this study implies that since the years of teaching experience serve as a determinant on the types of the contents that teacher professional developments are needed and on the teachers' perception of the effectiveness of such contents, the course of teacher development should be taken into consideration when the contents of teacher professional development programs are developed.

The purpose of this study was to investigate home economics teachers' perception of cultural diversity education, to provide an efficient educational material for the multicultural education in teacher education and teacher retraining. 160 Home economics teachers answered the survey questionnaires. To analyze the data, SPSS 19.0 for Windows was used to conduct frequency analysis, factorial analysis, credibility analysis, t-test, one-way ANOVA, and Duncan's multiple comparison. The results of this study were as follows. Four dimensions of cultural diversity education were derived by factor analysis: cultural equality, diversity implementation, diversity value, comfort with diversity. As for their awareness about cultural diversity education, it was in the order of cultural equality, followed by diversity implementation, diversity value, and comfort with diversity. The groups were significantly different according to demographic variables. As for the whole awareness about cultural diversity education and the diversity implementation, group of age 40 teachers recognized more highly than other groups. Furthermore, teachers outside Jeonbuk area recognized more highly the cultural equality, diversity implementation, diversity value than those in Jeonbuk, which is the 3rd high area in the nation of multicultural family proportion. As for cultural equality and diversity implementation, teachers over 15 years of experience, recognized more highly than other groups. Those with the teacher certification in the college of education, recognized more highly the cultural equality, diversity value, comfort with diversity than teachers from the other colleges. Teachers who need multicultural education, recognized more highly cultural equality, diversity implementation, awareness of diversity than those who don't. These results imply that in home economics education, there must be more systematic studies on school field education and related educational programs in order to revitalize multicultural education. And for teachers with highly recognizing cultural diversity to conduct a systematic multicultural education more efficiently, there should be both systematic pre-service education programs at college level and in-service education programs for the teachers in terms of cultural diversity education.

This study investigated mathematics teachers' views on education, teacher efficacy, and the relationship of teacher efficacy and Confucian Heritage Culture's views on education. In particular, the differences on the basis of teachers' teaching experience and academic level were examined. We identified teachers' views on education by investigating their views on the purpose of education and examining whether they support the perspectives of teaching and learning in Confucian Heritage Culture. The questionnaire was answered by a total of 572 elementary teachers and secondary mathematics teachers. The results of this survey revealed that mathematics teachers have both Confucian Heritage Culture's view and Western view on education and quiet strong teacher efficacy. The views on education differed by academic levels, but there were no differences in teaching experiences. The teacher efficacy was differed by both academic levels and teaching experiences. The correlation between teacher efficacy and Confucian Heritage Culture's view on education was low. Findings were discussed with regard to their implications for both Korean mathematics education and mathematics teachers' teaching practice.
