These days, with the emphasis on statistical literacy, the importance of communication is the focus of attention. Communication about statistics is important since it is a way of describing the understanding of concepts and the interpretation of data. However, students usually have trouble with expressing what they understand, especially through writing. In this paper, we examined preservice teachers' difficulties when they wrote about statistical concepts. By comparing preservice teachers' written responses and interview transcripts of the variance concept task, we could find the missing information in their written language compared to their verbal language. From the results, we found that preservice teachers had difficulty in connecting terms contextually and conceptually, presenting various factors of the concepts that they considered, and presenting the problem solving strategies that they used.

The purpose of this study was to investigate the needs of educators, learners and parents in elementary schools for implementing a systematic nutrition education program by nutrition teachers to begin in 2006. The subjects were 833 dietitians, 808 principals, 3,141 teachers, 7,577 students and 6,003 parents in elementary schools. A fairly large proportion of the principals (98.4%), teachers (95.5%), parents (96.6%) and students (62.8%) responded that nutrition education is urgently needed. Every dietitian, principal and teacher has recognized that for the enforcement of a nutrition program in the future, the placement of one nutrition teacher in every school is needed without a moment's delay. Many subjects responded that elementary low grades are the most proper time for nutrition education for students and it is also needed to extend this not only to students, but also parents and teachers who have a direct influence on them. In the education hour, they responded that it is proper one hour a month for teachers and one hour a week for students. Fifty-six percent of dietitians, 58.3% of principals and 67.0% of teachers responded that the best educational way to heighten the effect of nutrition education was education through discretional activities. It was found that 46.4% of students have wanted nutrition education to be enforced during special activities. Education through their school homepage or in-school broadcasting system, while it has been most utilized, was low in a degree of preference with 10.9%. In regards to a nutrition program, principals and parents have attached much importance to the dining etiquette, dietary attitudes, and relations of foodstuffs with health, while dietitians and teachers have made much of a balanced eating habit, and the relations of dietary life with health. Finally, for a nutrition program to be enforced towards a direction that the educators and students want, it is judged that first of all the role of nutrition teachers is the most important, furthermore the support of manpower and the budget should be made.

수학 교육에서 교사의 SMK와 PCK에 대한 역량은 대단히 중요하다. 그들의 SMK와 PCK에 대한 현황 파악과 그에 따른 강화방안이 있다면 더 없이 좋을 것이다. 그러나 교사를 대상으로 교수 역량 강화에 대한 연구를 수행하는 것은 현실적으로 많은 어려움이 있다. 이에 본 연구에서는 23명의 예비 초등교사를 대상으로, 이들의 SMK와 PCK에 대한 현황 파악과 그에 따른 강화방안으로 DGE 탐구활동을 활용하였다. 그 결과 3명의 예비 초등교사가 초기 SMK에서 오류를 나타내었으며, 초기 PCK에서는 설명 및 시각적 확인 위주의 교수 방법으로 문제해결에 필요한 성질을 지도하는 것에 중점을 두었다. 또한 DGE 탐구활동의 실제는 역동성 개념 이해 및 구현의 어려움, $75^{\circ}$ 작도에 집착 및 결과의 일반화, '접는 활동'의 수학적 해석의 어려움, 무난한 GSP 구현의 네 가지로 분류되었다. 이후 초기 SMK에서 나타난 하나의 오류가 수정되었으며 PCK의 방법적 측면에서 GSP를 활용한 시각적 확인이 추가되었다. 이러한 결과로부터 DGE가 예비교사의 SMK와 PCK 강화 도구로 활용될 수 있도록 돕는 몇 가지 교수학적 시사점을 추출할 수 있었다.

The purpose of this study is to investigate teachers' recognition and to suggest an improvement in the system of teacher's observation and nomination used to selecting gifted and talented students in Science in the Busan Metropolitan School District in 2013 by investigating teachers' recognition of the system and their expressed needs. The results are as follows. First, it was observed that teachers are of the opinion that it is difficult to determine the science gifted students by observation due to their lack of expertise in giftedness and gifted education, the lack of a check list to use, and the difficulty of ensuring the objectivity of the results of the determination. Second, the absence of objective screening tools used for the selection, the selection of gifted students based on their subjective judgment, and the possibility to select students based only on visible manifestations of ability may cause parents to mistrust the system. Thus, institutional support is required to address the concerns of teachers and parents. Third, the teachers who are in charge of observation, nomination, selection and determination need to be trained. After that, at least one of these teachers should be assigned in each school and training should operate continuously and systematically. Lastly, while these things are occurring, the process of observation and nomination of by teachers, which is the basis of pooling gifted students at the level of Busan Metropolitan School District, should be continued.

The purpose of this study is to investigate the opinions of teachers, directors, and parents about childcare teachers' facial expression language. We performed in-depth interviews based on literature and previous studies, which consisted of ten childcare teachers, ten directors, and ten parents. From the in-depth interviews, we are able to mainly conclude that all groups think that a childcare teacher's facial expression language is very important, and strongly influences interpersonal problems and work performance. Mostly, childcare teachers aim to have pleasant facial expressions. However they complain that in some situations it is difficult to do so, which causes severe stress. They argued that the facial expressions of both the director of the childcare center and the parents are also very important for children. However, the directors thought that teachers' facial expressions affect children and their parents' impressions of the teachers and quality of childcare. The parents are usually highly satisfied with the childcare when the teacher has a pleasant facial expression, which motivates the parents to have a positive impression of the teacher. Taken together, childcare teachers' facial expression language is critical for children and the childcare environment. Thus, developing an education program for facial expression language would be helpful for improving the quality of child care. Plus, childcare environments should be developed so that teachers do not experience difficulty in having pleasant facial expressions. This result might have the limitation of being collected from only female childcare teachers, directors, and parents.
