The need for polar education was further emphasized, depending on the importance of the pole, which is the best place for climate change detection and prediction, and treasure trove of future technology and resources. Therefore, this study analyzed the general cognitive and affective characteristics of elementary school students' polar literacy, and in addition, analyzed the cognitive and affective characteristics according to the level of diversity about polar experience. The items developed for the study were revised through a pilot survey of 43 fifth graders. They consisted of questions about gender, polar experience, scientific literacy, polar knowledge, polar literacy skills, polar literacy beliefs, and polar literacy attitudes. The types of questions used are selectable, reliable, and Likert (4 points), for a total of 66 questions. The students who participated in the study were 323 fifth grade elementary students. The study found that students were more interested in the dramatic consequences of polar changes than the scientific causes and processes associated with it. This is confirmed through the fact that they are more interested in and familiar with polar creatures suffering from polar changes than understanding ice, which is the main feature of and the central mechanism of polar changes. Students also recognized the issue of polar climate change as a global issue other than their own. They believe that what happens in the Arctic and Antarctica will affect the whole world, but not significantly to himself and his community. The level of knowledge about polar region and the ability to analyze and infer were not significantly related to each other, and students with a higher level of diversity of experience about polar region had a better understanding of polar science and technology. In this research, it is meaningful to check the characteristics related to the students' polar region and to use it as a basic data to show the direction in which polar literacy education should proceed in the future.

Because of the continuous low birthrates, the number of the elementary students will decrease by 17% in 2020 compared to 2011. The purpose of this study is to forecast the number of elementary school teachers until 2020. We used the data in education statistical year books from 1970 to 2010. We used the time-series regression model, time series grouped regression model and exponential smoothing model to predict the number of teachers for the next ten years. Consequently time-series grouped regression model is a better model for forecasting the number of elementary school teachers than other models.

This study sought to explore longitudinal changes in Korean fourth graders' career aspirations in science. The sample included those who had high interest, but low career aspirations in science, and the analysis focused on the concept of science identity. To achieve this study's objectives, we selected 14 participants and then conducted two in-depth interviews with them. Compared with the first interviews (4th grade), changes were observed in eight students' career aspirations in science in the second round (5th grade). While six students maintained "negative" career aspiration, six revealed "medium" and two revealed "positive" career aspiration in science. To explore the relationship between science identities and career aspirations in science, three students were selected from the sample for further study. According to the results, the aspects of science identity that students valued regarding potential careers varied individually. Depending on these aspects, each student showed different patterns in the interactions between different aspects of science identity, and between aspects of science identity and science-related career aspirations. Over time, participants' experiences and interactions with people around them produced changes in their science identity, which led to changes in their career aspirations resulting from the interactions between aspects of their science identity. Their career aspirations in science were also significantly influenced by each participant's perceptions of relationships with peers (i.e., recognition by peers and of peers) and of science-related careers. Therefore, the results suggest that students need to be provided with appropriate learning environments and guidance relating to science careers.

Typological theories of offending postulate that childhood-onset delinquents have a high likelihood of being serious and chronic offenders and that there are a distinct set of risk factors predicting early-onset antisocial behaviors. It is useful to empirically classify children into subgroups based on their deviant behaviors because it helps us to identify unique factors associated with each subgroup. Using the first two waves of the Korean Youth Panel Survey, Elementary School Data, this study aimed(a) to empirically classify 5th graders into latent delinquent subgroups, and (b) to examine the impact of individual, familiar, school, and peer factors on the latent delinquent classes. Latent class analysis yielded three latent classes based on 15 indicators of deviant behaviors - delinquent class, low-level delinquent class, & normative class. The results from multivariate multinomial logistic regression analyses revealed that being male, reporting low self-control, coming from poor family, high association with deviant peers, and being bullied increased the risk of being in the delinquent class. Moreover, low self-control, aggression, domestic violence, low level of attachment to teachers, and deviant peers independently increased the risk of being in the low-level delinquent class compared to the normative class. Based on the study findings, implications for practice as well as future studies were discussed.

Environmental problems can be dealt in the diverse areas such as engineering, public administration, and law. However, the education on environmental preservation is conceived as the fundamental solution for environmental problems, because the education can make the person of action. Specifically, building the attitude and habit of environmental preservation through environmental education is the effective and efficient way of environmental preservation. This research was conducted to develop an education system that is designed to build students' attitude and habit of environmental preservation through acquiring knowledge and functions of natural environment. The proposed system supports diverse learning activities such as writing, drawing, listening natural sounds and music, and problem solving. The system is technically designed on the Web to promote students' creativity and autonomy, and also are theoretically based on constructivism to build the will of environmental preservation. Moreover, the proposed Web-based system includes diverse functions such as classes, material resources, environmental quiz pool, environmental work gallery, which motivate students' learning activities. Therefore the proposed Web-based system is expected as an effective tool to achieve the goals of environmental education such as acquiring environmental knowledge and functions, building attitude of environmental preservation, and participating in the environmental preservation activities.

The purpose of this study was to provide information on adoptive families and obtain the basis data for adoption-related programs that are useful to adoptive families by examining their experiences in the adoption process, post-adoption adaptation, and adoption programs. For the study, in-depth interviews were conducted on six mothers who publicly adopted elementary school children and had expressed high satisfaction with adopted families and their willingness to participate in this research voluntarily. The main results exhibited parents' happiness post-adoption along with positive changes, such as internal growth, marital love growth, favorable response from others, and child's unexpected responses to adoption. However, open adoption mothers have coped with efforts to sympathize with and accept their children's feelings as they suffer from adoption, and with active support from their spouses, parents, and their own children. Open adoption mothers participated in various adoption-related programs, support, and voluntary self-help groups provided by adoption agencies or public organizations, and above all, their experience in self-help groups and peer groups of adopted children was found to be very useful. Based on these main results, we suggested strengthening welfare services for open adoption families, implementing education to better understand adoption, education for school teachers, students, and welfare staff, providing practical programs for adoptive families, and promoting self-help groups.

Recent reform movement in mathematics education has focused not only on the curriculum development but also on teachers' learning or professional development. Whereas various theoretical paradigms call for different programs of professional development for teachers, one of the common emphases is on the pedagogical content knowledge [PCK] which encompasses contents and methods to teach. Against this background, this study developed comprehensive instructional materials for the purpose of fostering PCK in mathematics for elementary school teachers with 17 essential learning themes such as fraction, plane geometry, and area. Each loaming theme was first summarized on the basis of literature reviews and surveys in terms of knowledge in mathematics contents, knowledge in teaching methods, and knowledge in students' mathematical understanding and learning. Each theme was then analyzed in detail on how it was represented in the national curriculum and its concomitant textbooks along with workbooks. Finally, this report included a reconstruction of one unit in textbooks per each learning theme, followed by teaching notes and suggestions from classroom implementation. This was intended for teachers to apply what they might loam from this material to their actual mathematics instruction. Given the page limit, this paper dealt only with the learning theme of ratio.

The purpose of this study was to find out the effects of climate change education program focused on the keeling curve activities highlighting inquiry process on elementary students' climate literacy. Most of the students have not been able to correctly understand just how serious phenomenon that the temperature rise of the last 100 years is. As a result, there is educational limitations in order to bring about a substantial change in the attitudes toward climate change. So the development program was applied to various questions and explored strategies in order to compare with past climate change data. The results described that 46 students in the experimental group had statistically significant effects on cognitive domain, critical thinking of affective domain and practical domain. In addition, as a result of the analysis of teachers' instructional perspectives and students interview, they supported the researcher's opinion that the developed program could help students improve the climate literacy.

In this study, We analyzed the mathematical thinking of sixth grade students showed mathematics lessons through the application of Lakatos' methodology and search for the role of their teachers in this lessons. We supposed to find the solution to the way of teaching-learning regarding the Lakatos' methodology for the elementary school level. According to the stages of presenting a problem situation, suggesting an initial conjecture, examining the conjecture, and improving the conjecture, we had lessons 8 times that are applied to Lakato's methodology. We gathered and analyzed data from lessons and interviews recording videotapes, documents for this study. The participants showed a lot of mathematical thinking. They understood the problem situation with the skill of fundamental thinking and suggested the initial conjecture by the skill of developmental thinking and they found a counter-example to be able to rebut the initial conjecture by critical thinking. Correcting the conjecture not to have counter-example, they drew developmental thinking and made their thinking generalize.
