The dissemination of smart appliances, along with the development of the latest information and communication technology has an effect on society. Their application can be seen in the smart learning environment, by use of digital textbooks with smart devices in the classroom. Hence in this study, the 4L-ACC activity using digital textbooks was applied in the third grade social studies class to improve critical thinking and problem solving skills of elementary school students. This study compared and analyzed the impact in critical thinking and problem-solving skills using digital textbooks versus standard social studies classes. As a result, in social studies classes that used the 4L-ACC activity compared to common social studies classes, elementary student's problem understanding, critical thinking, problem resolution, reflective thinking, and all lower areas of critical thinking and problem-solving were improved. In conclusion, using digital textbooks enhance student's ability to think critically and problem solve. This should provide learners a more comprehensive learning experience and therefore be integrated into more education environment.

The purpose of this study is to analyze the errors and difficulties which pre-service secondary teachers shows during the task modification in consideration of the cognitive demand and to provide significant implications to the pre-service teacher education program related to the modification of the mathematical tasks. In the pursuit of this purpose, tasks were selected from perpendicular bisector units and 24 pre-service teachers were asked to modify the tasks to higher and lower level tasks. After the modification activities, opportunities for reflection and modification were provided. The findings from analysis are as follows. Pre-service teachers had a difficulty to distinguish between PNC tasks and PWC tasks. Also, We identified the interference phenomena that pre-service teachers depended on the apparent elements of the task. Pre-service teachers showed a tendency to overlook the learning objectives and learning hierarchy during the task modification, and to focus on some types of task modification. However, pre-service teachers were able to have meaningful learning opportunities and extend the category of tools to technology including Geogebra through self-reflection and correction activities on task modification. The above results were summed up and we presented the implications to the task modification program in the pre-service secondary teacher education.

Students need to have opportunities to share their ideas with peers by taking part in the conversation voluntarily that is, by persuading others and reflecting the consequences. Recognizing the importance of this point, this study intended to examine students' argumentation occurring in the process of performing tasks in the math classroom. Also, it tried to explore the types of the argument that students used in the classroom and the reason why they employed them with a focus on 'rebuttal', which is one of the six elements of the argument scheme such as claim, data, warrent, backing, qualifiers, and rebuttal. The analysis of argumentation is based on the five argumentation schemes suggested by Verheij(2005). The experimental class was conducted twice a week with four participants who are third grade middle school students. In the argumentation class students were promoted to address two different kinds of geometrical tasks. After the second session of class, the researcher conducted the semi-structured interview. Accordingly, this study contributes to the existing research by making students to have concrete and active argumentation while obtaining the sound understanding of the argumentation.

일본의 종교계는 2001년에 일어난 미국에서의 동시다발적 테러사건 이후, 적극적으로 평화를 위한 활동에 뛰어 들었다. 가령 뉴욕에 본부를 두고 있는 세계종교자 평화회의(WCRP)는 일본 종교교단들이 상당히 깊숙이 관여하고 있는 세계적 규모의 종교협력단체로서, 미국에 의한 보복공격의 억제를 꾸준히 그리고 강력하게 호소해 왔다. 1970년에 설립된 이 세계종교자 평화회의의 설립자 가운데 한 사람이자, 30여년에 걸쳐 지도적인 역할을 수행해 온 인물로서 입정교성회(立正佼成會)의 개조인 니와노 닛쿄(庭野日敬)를 들 수 있다. 니와노는 1930년에 법화경에 의한 선조 공양의 가르침을 깨달은 후, 불교의 핵심이 이타행 실천에 있다고 가르치면서 열심히 포교활동을 계속해 왔다. 1950년대 이후에는 종교협력과 사회참여에 적극적으로 전념했으며, 그 결과 입정교성회의 종교활동 전체 속에 평화운동이 큰 부분을 차지하게 되었다. 니와노는 불교의 가르침이야말로 평화를 실현하기 위한 핵심적인 사상을 담고 있다고 설한다. 즉 자연과 타자 사이에 조화로운 관계가 유지되도록 평화의 마음을 실현해야 한다는 가르침이 그것이다. 특히 분노와 질투와 공격적인 마음을 가지지 말며, 자비의 마음으로 타자를 대면하는 것이 중요하다는 것이다. 그는 이것이 우주 본래의 실재와 합치함으로써 가능하다고 주장한다. 이처럼 모든 것이 일치할 수 있다고 굳게 믿는 니와노는 종교협력이 평화실현에 있어 중요한 방법이라고 간주한다. 그런데 니와노가 '평화주의국가 일본'이라는 이념에 많은 부분을 의거하고 있기는 하지만, 이런 이념이 과거의 전쟁에 대한 일본의 충분한 반성에 입각한 것인지는 의문의 여지가 있다. 나아가 그는 상이한 종교간의 일치 가능성에 대해 다소 낙관적이며, 또한 불교와 동양사상이 평화를 지향한다는 이해에 대한 비판적인 성찰이 미약하다는 한계를 안고 있다. 그럼에도 불구하고 일본의 민속적 종교토양에서 생겨난 종교적 평화주의의 이상 및 실천으로서, 니와노 닛쿄와 입정교성회에 대해서는 충분히 검토해 볼 만한 가치가 있다고 여겨진다.

This study dealt with two case studies of the development of beginning science teachers' pedagogical content knowledge (PCK). This study was grounded on the idea that teacher thinking and classroom behavior are related to each other in a reciprocal way. Teachers' PCK influences teaching practices, while in a reverse way teaching activities influence teachers' practical knowledge. Two beginning science teachers participated in this study. Data collection consisted of classroom observation, interviews, reflective journals and lesson plans. For data analysis, we conceptualize pedagogical content knowledge for science teaching as consisting of four components: (a) knowledge about science matter, (b) knowledge about students' understanding of science topics, (c) knowledge about instructional strategies for teaching science, (d) knowledge about assessment in science. The outcomes of this study revealed that there was a large gap between beginning science teachers' intentions for teaching science and their practice. To give beginning teachers more opportunities to incorporate their knowledge base for teaching, we propose that they need to be involved in a real teaching situation at schools rather than in the university.

This study examines the effects of adolescents' volunteer activities on their development of sense of community. When examining the effects of volunteer activities, both quantity and quality sides of volunteer activities were considered in the research model and besides the direct effects of volunteer activities on their sense of community, the mediating role of self-esteem and peer attachment were also examined. The data set of conducted by National Youth Policy Institute was reanalyzed for this study. The subjects of this study were 1,426 first-grade middle school students who had experiences of volunteer activities. The results of the study are as follows. First, the total hours of volunteer activities and the satisfaction with volunteer activities were positively related to their sense of community respectively. In an integrative model which combines both quantity and quality aspects of volunteer activities, however, only the satisfaction with volunteer activities was found to be significant. This means that the satisfaction with and reflective learning after volunteer activities are more important sides of adolescents' volunteer activities than whether and how many times they had experiences in volunteer activities. Second, the satisfaction with volunteer activities was found to enhance adolescents' self-esteem and peer attachment and the changes in their personal traits again led to a higher sense of community. Therefore, both the direct effects of volunteer activities and indirect effects through self-esteem and peer attachment were proved. Based on the results of the study, the need and ways to improve the management system of adolescents' volunteer activities were suggested.

The purposes of this study were to investigate pre-service mathematics teachers' perceptions of the role of cooperating teachers and teacher interactions during teaching practicum. Thirty-four pre-service mathematics teachers who finished student teaching participated in the study. The researcher collected data from various sources such as a questionnaire, interviews, and written documents. According to the results of the study, more than 50 percent of the participants showed negative responses to all of the questionnaire items on teaching activities or guidance of cooperating teachers. Cooperating teachers mainly played a role in the stage of reflection of student teacher's teaching practice, and they provided specific feedback and guidance of teaching and learning methods and contents. Cooperating teachers played roles as (mathematics) teacher educators, classroom observers, and co-teachers, but their roles as teacher educators or co-teachers should be more stressed for pre-service mathematics teachers' professional development.
