The purpose of this study is twofold: (i) to argue the importance of problem solving strategy in education and (m to propose an efficient way to use the problem-solving strategy, which is based on the survey to find out how well elementary school teachers recognize the importance of the strategy. Forty elementary school teachers participated in the survey. The result of the survey shows that they do not use various strategies when they solve problems. It also shows that the rate of wrong answers the teachers get when solving problems is pretty high because they adopt a wrong strategy. It is prerequisite that teachers recognize the importance of the strategy when solving problems and put into practice various strategies in order to help their students improve their problem-solving abilities.

Recently, as the educational paradigm shifts from teacher-centered to learner-centered, the active construction of knowledge of learners is becoming more important. Accordingly, classes using mathematical modeling are receiving attention. However, existing research is focused on teachers or middle and high school students, so it is difficult to apply the contents and results of the research to preservice teachers. Therefore, in this study, the experience of mathematical modeling was examined for elementary school preservice teachers. And we looked at how positive experiences of mathematical modeling change their perceptions. As a result of the study, elementary school preservice teachers had very little experience in mathematical modeling during their school days. In addition, it was found that the perceptions changed more positively than when a theoretical class on mathematical modeling was conducted, rather than when the experience of mathematical modeling was actually shared. Based on the results of this study, implications were suggested in the course of training preservice teachers.

This study investigated the level of academic passion for elementary school teachers' science pedagogical content knowledge (PCK) and examined the factors that influence the passion. To this end, 161 elementary school teachers in Seoul were selected, and academic passion tests were then administered to evaluate their academic passion for science subject matter knowledge and science pedagogical knowledge. Individual in-depth interviews were also conducted with some of the participating teachers. The results revealed that 'importance' and 'harmonious passion' for learning science subject matter knowledge and science pedagogical knowledge were found at a high level. However, 'time/energy investment' and 'obsessive passion' for learning the knowledge were slightly higher or lower than normal. The 'like' for learning science subject matter knowledge was relatively high, but the 'like' for learning science pedagogical knowledge was slightly higher than normal. The differences in academic passion for science subject matter knowledge and science pedagogical knowledge were greater according to advanced major at undergraduate than teaching career. The teachers evenly selected some factors that influenced their academic passion for science subject matter knowledge and science pedagogical knowledge. These identified characteristics included 'individual interest', 'high school track', 'experience in advanced major at undergraduate', 'experience in science-related graduate school', 'experience teaching science in elementary school', 'experience teaching science at the gifted education institute', 'experience in charge of science subject teacher', 'experience in science-related teacher training', 'experience in developing science-related teaching and learning materials', 'experience in charge of science or science-gifted related work', and 'experience in a science-related teacher community'. However, a slight difference was noted in the selection ratio depending on advanced major at undergraduate. Based on these results, the practical implications for improving their academic passion for science PCK are suggested.

The purpose of this case study is to get an implication on elementary pre-service teacher education programs by exploring how a pre-service teacher's noticing changes within a learning community. The pre-service teacher participated in a learning community with researchers. Data includes recordings and transcription of actual class and pre- and post discussion in the learning community, the pre-service teacher's reflection essays, field notes, and students' worksheets. Results are as follows. First, the pre-service teacher's attending moved from the result of tasks to students' mathematical thinking. Second, the pre-service teacher's interpretation changed from a lack of diversity and specificity of evidence to diversity and specificity. Third, the pre-service teacher's decision-makings changed from unproductive deciding to productive deciding.

In this study, I investigate the relationship between mathematics anxiety and mathematics teacher anxiety of elementary school teachers with integrated method. As a result of statistical analysis of the survey of 256 elementary school teachers, there was a statistically significant positive correlation between the two factors (r = .630, p <.05). The analysis show that teaching experience and degree may affect mathematics anxiety and teaching experience, degree, and teacher qualification may affect mathematics teaching anxiety. Subsequently I conduct a qualitative study focusing on interviews with 20 elementary school teachers. As a result of the analysis, I confirm that even if the mathematics anxiety is low, mathematics teaching anxiety may occur due to the teaching environment. As a result of the quantitative and qualitative analysis of this study, Korean elementary school teachers' mathematics anxiety and mathematics teaching anxiety might be regarded as separate factors. From the result of the study, I suggest that mathematics anxiety and mathematics teaching anxiety of elementary school teachers, each emotional state might be considered as independent emotional status. The implication of the study indicate that independent methods might be developed in order to prevent and treat mathematics anxiety and mathematics teaching anxiety in elementary school teachers.

제7차 교육과정에서는 초등학교에서의 인터넷 소양을 권장하고 있다. 인터넷을 교육에 활용하는 형태는 다양하지만 학교에서 이루어지는 활용은 정보검색이 주된 목표가 되고 있다. 학교서버를 구성하거나 도입하여 교육적으로 활용하는 방법에는 여러 가지가 있겠지만 본 연구에서는 리눅스를 이용한 서버를 구성하도록 제안하며 서버의 구성시 고려해야 할 점과 학교망에서 인터넷 서버로서 활용할 수 있도록 제안하고 있다. 학생과 교사간, 학교와 학부모간에 일어지는 교육활동의 한 부분과 교사의 업무를 인터넷 망을 이용하여 효율적으로 이용하다는 것은 교육의 참여도를 높여줄 뿐만 아니라 정보화에 대비하는 미래교육이 될 수 있는 것이다.

The efforts on order to enable students to connect meaningfully their real life to mathematical application and mathematical problem solving would be one of the significant functions in school mathematics. In this research, we surveyed 582 elementary school teachers in Seoul to determine their perception and the status about mathematical modeling. The goal of the research was to analyze the survey and interview and investigate the possibility of application of mathematical modeling to elementary mathematics. As a result, they replied that mathematical modeling would be applicable for students' understanding of concepts and motivations.

The purpose of this study was to develop and validate a scale of Korean elementary teachers' mathematics beliefs. We examined 299 elementary teachers' mathematical beliefs using 30 items, out of which 12 items covered beliefs about the nature of mathematics and 18 items covered beliefs about mathematics teaching and learning. In the first stage, we performed exploratory factor analysis using 149 survey data to examine the factor structure. In the second stage, we performed confirmatory factor analysis using 150 survey data. Building upon previous studies, we examined the construct validity of three different models to find the best factor structure. The study results indicate that the four-factor model with 14 items provides the best fit for the data: transmissive view of mathematics, constructivist view of mathematics, transmissive view of teaching and learning, and constructivist view of teaching and learning. The findings of the study reveal that each factor has adequate internal consistency and reliability. These results confirm that the beliefs scale is a reliable and valid measurement tool to measure Korean elementary teachers' mathematical beliefs. The implications of the study are discussed.

This study analyzes the content validity of descriptive tests developed for elementary schools, in order to acquire basic data to improve them. Various descriptive tests were collected and tested for differences in proportions between two-dimensional classification of educational objectives and the level of behavioral objectives. Results show that the descriptive tests developed by elementary school teachers mainly focused on "knowledge" and "understanding," and that content validity for behavioral levels to be low. Nine elementary school teachers were interviewed to understand the result. From the interviews, we found both internal and external factors that cause low content validity. The main internal factors were teachers' ability to make two-dimensional classification of educational objectives, the teachers' consideration of students' level, item level of difficulty, the ease of scoring, and path dependence. The main external factors were curriculum, parents, and administration. Based on the results, we suggested the factors related to elementary school teachers' PCK of descriptive tests.

This study is part of a larger project that investigated the patterns of children's use of educational graphic novels (EGNs), a publication format that has been popular among young readers in Korea since 2000. In-depth interviews with elementary school teachers and school librarians uncovered tension and gaps between these adult professionals and children's enjoyment of the format. Interviewees' views on EGNs ranged from limited tolerance to a potential candidate for high-interest / low-vocabulary reading. All teachers and school librarians urged for guidelines and criteria for selecting and evaluating EGNs for children.
