Purpose: To determine factors of kindergarten teachers' willingness to perform cardiopulmonary resuscitation (CPR) and to suggest education methods toward CPR. Methods: We interviewed 92 kindergarten teachers trained to administer CPR. Among them, 74 answered the questions regarding CPR experience, barriers, and willingness. Logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (CIs) for the association of willingness factors to cognition, performance, and attitude toward CPR. Results: Of the participants, 73 (98.7%) were female, 32 (43.0%) were in their twenties (mean age: 33.9 years), 31 (41.9%) graduated college, 47 (63.5%) had < 10 years of tenure, and 65 (87.8%) and 62 (83.8%) indicated willingness to perform CPR to family members and kindergarteners, respectively. Barrier factors included fear of performing CPR incorrectly (46.8%) and injuring the victim (25.6%). Willingness factors included understanding brain death (37.7%) and performing CPR correctly (26.1%). Willingness predictors included attitude toward family members (OR: 4.54, 95% CI: 1.19 -17.39, p = .027) and kindergarteners (OR: 3.07, 95% CI: 1.15-8.22, p = .025), and cognition to kindergarteners (OR: 0.36, 95% CI: 0.13-0.99, p = .050). Conclusion: The kindergarten teachers were more willing to perform CPR to family members and kindergarteners than to others in an attitude-dependent manner.

Many middle school students have difficulty in understanding biological concepts because too many concepts are presented in the textbook compared to limited school hours. So, it is necessary to select concepts which are indispensable. The purpose of this study is to select key concepts in the unit 'The Continuity of Life' by surveying students' and teachers' cognition on the concepts. In this study, 78 concepts were extracted from 'Science 3', unit II 'The Continuity of Life'. To survey how students and teachers think the concepts, Likert type questionnaires were made. 300 third grade middle school students and 34 biology teachers were selected by random sampling and the questionnaires were applied. The following results were obtained:1. Students thought 59 concepts out of 78 were important and the mean score of important level of the concepts was 3.60. Students thought 26 concepts out of 78 were difficult and the mean score of diffculty level'of the concepts was 3.26. The more they think the concepts important, the more they think them difficult (r=0.7462, p<0.001). 2. Teachers thought 55 concepts out of 78 were important and the mean score of important level of the concepts was 3.82. Teachers thought 33 concepts out of 78 were difficult and the mean score of diffculty level of the concepts was 3.31. The more they think the concepts important, the more they think them difficult (r=0.6138, p<0.001). 3. The selected concepts were considered more important by teachers than by students(t=2.0150, p<0.05). However, there was no significant difference in evaluating the difficulty level of the concepts(t=0.7327, p>0.05). 4. It was found that students have difficulty in understanding concepts when they are presented in the textbook to require formal preparation than concrete preperation(t=2.6612, p<0.05).

본 연구에서는 중등학교에서 가르치는 두 유형의 산-염기 모델에 대한 화학 교사들의 인지 수준을 분석하였다. 이를 위하여 각 모델이 가지는 '이그노런스'를 분석한 선행 연구를 토대로, 교사들의 인지를 알아보는 설문을 개발하였다. 설문은 두 모델에 대한 불일치 상황을 제시한 산과 염기 반응에 관련된 문항과 산과 염기 해리와 관련된 문항 등 2문항이었다. 연구 대상자는 15명의 화학 교사들이었으며, 설문 분석 결과, 4가지 수준으로 교사의 인지가 분석되었다. 4가지 수준은, 모델을 모르는 경우, 한 모델만 이해하는 경우, 두 모델을 이해하고, 한 모델의 '이그노런스'를 지각하는 경우, 두 모델을 이해하고 두 모델의 '이그노런스'를 지각하는 경우였다. 가장 큰 비율의 교사들은 두 모델을 이해하고, 한 모델의 '이그노런스'를 인지하는 경우였다. 그러나 두 모델을 이해하고 두 모델의 '이그노런스'를 지각하는 경우의 비율은 매우 적었다. 이를 통해 모델과 '이그노런스'에 대한 화학교사들의 인지 수준을 높이기 위한 노력이 필요함을 주장하였다.

This study examined the relationships between the cognitions and strategies of child's problem behaviors depending on the level of preschool teacher's professional development. Participants were 176 preschool teachers in B Metropolitan city. The teachers completed rating scales to measure teacher's professional development, the perception of child's problem behaviors, and teacher's guiding strategies for child's problem behaviors. The collected data were analyzed using descriptive statistics, one-way ANOVA, and Pearson correlations. Results showed that there were different cognitions of child's problem behaviors depending on the level of teacher's professional development. Secondly, child's problem behavior guiding strategies by the level of teacher's professional development were significant differences in the positive prevention strategy I, II, and the positive reaction strategy. Finally, there were somewhat different relationship between the cognition of child's problem behaviors and the problem behavior guiding strategies according to the level of teacher's professional development. Findings are discussed in terms of the importance of teacher's professional development in the context of teacher's education planning for teacher's guiding strategy about preschooler's problem behavior.

The purpose of this paper is to analyze and discuss the viewpoint dealing with the fundamental figures-point, line segment, and angle-of elementary school teachers. In fact, our main subjects in this article are as follows; how do elementary school teachers deal with the fundamental figures?, what is the general notion about the fundamental figures of elementary school teachers? Our such subjects come from the survey results about the 'fundamental figures in J. A. Ko(2009); the elementary school students have a tendency to regard the fundamental figures as not mathematical figures. In this article, we discuss mainly the meta-cognitive shift in the transform of notion, for example, from 'congruent' concept to 'equal' concept, about the fundamental figures.

The purpose of the study was to examine the effects of preschool teachers' qualification (education level, teaching experience, major, and certification) and competency variables (teaching efficacy and teacher-child interaction) on young children's development (cognition, language, and social development). The data came from $5^{th}$ Wave of Panel Study on Korean Children (PSKC) from the Korea Institute of Child Care and Education, and the multiple regression analyses as well as Pearson's correlation analyses were used. The results showed the positive associations between teachers' competency (teaching efficacy and teacher-child interaction) and child development. However, we did not find significant effects of teachers' qualification on young children's development. Based on the results, we proposed a policy implication that teacher qualification needed to be discussed with teacher competency to improve teacher quality.

In this study, a survey was conducted of students in grades 7 through 12, student teachers enrolled in their senior year at teachers' colleges, and science teachers. Subjects were surveyed on their conceptions of phenomenon related with dissolution, saturation, and extraction. The models and analogies used by student teachers and science teachers to explain dissolution were sought. The highest percentage of students thought of dissolution as a phenomenon in which particles broke into the spaces between other particles. The models or analogies used by the highest percentage of science teachers were similar. They generally conceived of dissolution phenomenon through what we call the 'space conception'. A conception of dissolution phenomenon as 'hydration through attraction of solvent and solute' was held by more student teachers than science teachers; there were some differences, however, according to their academic background. The percentage of teachers professing this view decreased when they attempted to explain the process of extraction of matter in a solution after other matter had dissolved or after the solution was cooled, indicating that the 'hydration' conception was not firmly established in the student teachers' cognition. Therefore, it can be inferred that the conceptions of dissolution as 'hydration' were transformed into the conceptions of dissolution as 'space' after teaching dissolution phenomenon as practicing teachers. This finding should be considered in teacher-training courses.
