  • The purpose of this study is to draw an educational implication by analyzing the context of narrative texts, students' narrative thinking, and their academic achievement. We investigated text types in students' geological field trip reports, the reason why students favors narrative texts, the relationship between narrative texts and their scientific knowledge recall, and the relationship between narrative thought and academic achievement. All students used expository texts, 82% of them expressed argumentative texts, and 36% of them used narrative texts. It is likely that students use more narrative texts because students were in the context of outdoor activity and so, their emotional feelings were more activated than when they are doing lab activities. The academic characteristics of earth science seemed to contribute more narrative texts in students' reports. The post-test revealed that students with narrative texts recalled better than the others. On the other hand, there were no statistically meaningful differences in academic achievement between the two groups. However, we have noted that female students whose reports contain narrative texts achieved significantly higher scores than female students whose reports are without narrative texts. From in-depth interviews, we found that students who properly used both paradigmatic and narrative mode of thought were in a more advantageous position than those who used narrative thought only. It was also found that some narratively thinking students tended to feel uncomfortable with the way of learning or evaluating questions about science. In the future, a complementary approach of narrative and paradigmatic mode of thoughts would be encouraged by understanding students' tendency of thinking.

Analysis of Scientific Explanations and the Affordances Constructed in Gifted Elementary Students' Science Drawings and Science Writings about Air Pressure: Pedagogical Use of Multimodal Representations (공기 압력에 대한 초등영재 학생들의 과학그리기 및 과학글쓰기에서 구성된 과학적 설명과 어포던스 분석 - 다중모드적 표상의 교육적 활용 -)

  • Scientific explanation is composed of various representations such as texts, diagrams, and graphs, and each representation contributes to expanding scientific meaning by connecting similar but slightly different meanings as a 'mode'. Based on this perspective of social semiotics, we aimed to identify the characteristics of meaning formation demonstrated in students' science writing (verbal mode) and science drawing (visual mode) and to discuss the pedagogical use of multimodal representations. To that end, 18 science drawings and 18 scientific writings constructed by science-gifted elementary students on air pressure were collected. The characteristics of the drawn and written explanations were then analyzed from the affordance perspective in social semiotics. In science drawing, students showed a tendency to use the affordance of the visual mode to infer concrete changes from the particle view, such as the movement of air particles, the number of air particles, and the collision of particles. In science writing, students used the affordance of the verbal mode mainly to infer the causal relationship between the concept of air pressure and other related factors at an abstract level. Based on those results, we discuss the educational implications and provide concrete examples of how to use the unique affordances of each form to complement one another.

  • Sensor nodes depend on batteries for energy source in Wireless Sensor Networks (WSNs). Low Energy Adaptive Clustering Hierarchy (LEACH) is a representative cluster-based routing protocol designed to ensure energy use efficiency whereas the virtual cluster exchange routing (VCR) information only with its closest node to build a network. In this paper, a protocol scheme was proposed wherein member nodes are designed to compare the currently sensed data with the previously sensed one and to switch to sleep mode when a match is achieved. The design is to help improve the transmission energy efficiency too.

  • Purpose: This study was done to investigate the predictors of maternal confidence between primipara and multipara mothers. Methods: The participants enrolled in this study were 145 mothers between 2 and 5 days postpartum. Data were collected using a questionnaire and analyzed using descriptive analysis, t-test, $X^2$ test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression. Results: The predictors of maternal confidence among primipara mothers were social support, self-esteem, mode of delivery ($R^2$=.287, p<.001). Whereas, gender of baby, antenatal fetal attachment, and educational status explained maternal confidence among multipara mothers ($R^2$=.270, p<.001). Conclusion: The results indicate that when nurses develop programs to encourage maternal confidence for new mothers, they should take into account the differences between predictors of maternal confidence according to the mothers' experience of birth.

  • In Jamaica Kincaid's novel Lucy, the narrator grows up with the burden of colonial legacies embedded with Englands' imperial disciplinary projects, its language, educational institutions, discourses. Colonial education interpellates the narrator into a colonial subject through its multiple ideological discourses and systems. Teaching the literature of England is the most insidious form of the Empire's disciplinary colonial projects, more powerful than military enforcement: Its mode of operation is creating phantasy and instigating and planting desire for such phantasy. As Homi Bhabha aptly theorizes as colonial mimicry and ambivalence, the narrator as colonial subject grows up split and confused as an ambivalent subject, simultaneously mimicking and desiring for the phantasized England as real, while resisting and criticizing such up-bringing and mimetic desire. This paper explores Kincaid's rhetorical strategy of employing Wordsworth's poem, "I Wandered as a Lonely Cloud," especially her use of the flower "daffodil." Employing the concept of "daffodil gap" suggested by postcolonial critics, this paper closely examines two episodes involving the flower daffodil in the novel, one in a colonial classroom and the other in a garden in a new world and suggests that Kincaid accomplishes intertextual critique of colonial education and imperial projects.

  • The main purpose of the study is to identify the key aspects of the use of innovative distance learning technologies in the training of biology students. Currently, there is a modernization, the evolution of the education system from a classical university to a virtual one, from lecture material teaching to computer educational programs, from a book library to a computer one, from multi-volume paper encyclopedias to modern search databases. During studies in higher education, distance learning ensures the delivery of information in an interactive mode through the use of information and communication technologies. The main disadvantage of distance learning is the emotional interaction of the teacher with students. It is necessary to increase the level of methodological developments for independent studies of students. The methodology includes a number of theoretical methods. Based on the results of the study, the main elements of the use of innovative distance learning technologies in the training of biology students were identified.

  • There were misgivings that the teachers in charge might not have enough understanding of the true purpose of teaching "Information". To learn about the general attitude of those teachers, the research group of private schools in Osaka began a project, 'The Public Presentation Caravan', in which teachers who had already started using information tools opened their class to teachers from other schools and exchanged ideas. It may be deduced that the combination of the two forums for exchanging opinions, one is held on the internet and the other face to face, is important. Teachers' community exists on the point where these two environments meet. Through this project, we might suggest creating a new mode of teachers' community using a network will be indispensable for the new teachers training.
