The software education to elementary students will be conducted from 2019. One of highlights of software education is a programming experience. It requires a higher level of programming education to students that are interested in programming. This problem can be solved by the club activities. But the materials for programming education for elementary students is not much. Therefore, we developed a programming material for club activities of the elementary school. We did not develop it as a programming manual. The students can understand a problem, can design through decomposition and abstraction processes, and can write a program when they are learning with this material. As a result, we expect that they can enhance their computational thinking abilities. We proved that our material is suitable for elementary students through a demonstration class. Therefore, we expect that our development methodologies for the material for programming education will contribute to develop a material for programming education.

A mathematics pre-service teacher T analyzed American mathematics textbooks and developed his teaching material for instruction. This study analyzed his thinking processes and results in the view of semiotics. If we regard the textbook as a sign and the unitary conversion that students should learn as an object of the sign, the interpretant of the sign is the pre-service teacher's analysis, which is conducted at the aspects of a subject matter knowledge and student understanding. T interpreted the textbook versatilely in terms of his knowledges and experiences. He developed his teaching materials as diagrams, did the diagrammatic thinking and became to have the hypostatic abstraction. This study is significant because it used semiotics for explaining T's thinking process.

Purpose: The purpose of this study was to identify the predictors of clinical competence in new graduate nurses. Methods: The subjects of this study were 238 nurses at 13 general hospitals who have had less than 12 months of nursing experience. The data were collected by structured questionnaire from August 5 to August 31 of 2009 and analyzed by the SPSS Win 12.0 program. Results: The total mean score for clinical competence was $181.05{\pm}15.17$, critical thinking disposition was $94.65{\pm}8.12$, and practice environment was $41.00{\pm}5.55$. There were significant differences of clinical competence according to the GPA (t=-3.58, p<.001), the number of beds in the hospital (t=-3.22, p=.001), instruction by preceptor (t=-2.32, p=.021), and previous experience of clinical practice in the hospital (t=-2.21, p=.028). Additionally, critical thinking disposition and practice environment were positively correlated to clinical competence (r=.50, p<.001; r=.20, p=.002). In multivariate approach, predictors included in this study explained 43% of variance in clinical competence. Significant predictors of clinical competence were critical thinking disposition ($\beta=.50$, p<.001), practice environment ($\beta=.14$, p=.012), and working duration ($\beta=.13$, p=.018). Conclusions: Based on these findings, it is needed that providing supportive practice environment and developing curriculum for enhancing the critical thinking disposition to improve the clinical competence in new graduate nurses.

Hangang Artpark construction is an enterprise founded in 2018 that involved installing public artworks created by 37 different people (teams) in Hangang Park located in Yeouido and Ichon Park. An iconic public space in Seoul, Hangang Park is turning into an even better public space due to the efforts to change the park into an eco-friendly, cultural-artistic space in tandem with the change in times. The objective of the Hangang Artpark construction business is to augment the environmental and scenic value of Hangang not only to provide a space for leisurely activities but also to revive it as a cultural-artistic area. This is a study of the concept and the design and installation processes of "Thinking of each other", a project by the Hangang Artpark construction business. This art piece has been installed in the wetlands and it trails along Ichon Hangang Park, which was created during the environmental recovery project. The piece consists of sculptures molded into animal shapes that are unique to the location and ecology of the area, displayed in harmony with the park's street furniture. By showing the coexistence of animals that existed in Hangang in the past along with the current inhabitants and the natural enemies of these inhabitants, the piece displays an ecofriendly scene. Moreover, by incorporating this piece into the street facilities of the park, such as gazebos, streetlights, surveillance cameras, and perches, the piece exhibits a different kind of street view compared to the installation style of other conventional environmental artworks. The various sculptures are installed along with the street facilities throughout the trail, rather than in a specific location intended for artworks, thereby achieving harmony with the park scene. In so doing, the piece elicits in the beholder an environment-friendly way of thinking, and at the same time, gives them a sense of calm and pleasure. Further, the paper researches the methods of safely installing art pieces in public spaces and of maintaining these installations.

Mathematical modeling can be described as a series of processes in which real-world problem situations are understood, interpreted using mathematical methods, and solved based on mathematical models. The effectiveness of mathematics instruction using mathematical modeling has been demonstrated through prior research. This study aims to explore insights for mathematical modeling instruction by analyzing the metacognitive characteristics shown in the mathematical modeling cycle, according to the mathematical thinking styles of elementary math gifted students. To achieve this, a mathematical thinking style assessment was conducted with 39 elementary math gifted students from University-affiliated Science Gifted Education Center, and based on the assessment results, they were classified into visual, analytical, and mixed groups. The metacognition manifested during the process of mathematical modeling for each group was analyzed. The analysis results revealed that metacognitive elements varied depending on the phases of modeling cycle and their mathematical thinking styles. Based on these findings, didactical implications for mathematical modeling instruction were derived.

Much has already been learned about what goes on in the minds of second language writers as they compose, yet, oddly enough, until recently little in the L2 research literature has addressed writing and mental imagery together. However, images and imaging (visual thinking) play a crucial role in perception (the basis of mental imagery), in turn, affecting language, thinking, and writing. Many theorists of mental imagery also agree that more than just language accounts for how we think and that imagery is at least as crucial as language. All of these demands, to be sure, are compounded for EFL students, which is why I investigate EFL students' writing process, focusing on the use of mental imagery and its relationship to the writing. First I speculate upon some ways that imagery influences EFL students' composing processes and products. Next, I want to explore how and whether the images in a writer's mind can be shaped effectively into a linear piece of written English in one's writing. I studied two university undergraduate EFL students, L and J. They had fairly advanced levels of English proficiency and exhibited high level of writing ability, as measured by TOEFL iBT Test. Each student wrote two comparison and contrast essays: one written under specified time limitations and the other written without the pressure of time. In order to investigate whether the amount of time in itself causes differences within an individual in imagery ability, the students were placed under strict time constraints for Topic 1. But for Topic 2, they were encouraged to take as much time as necessary to complete this essay. Immediately after completing their essays, I conducted face-to-face retrospective interviews with students to prompt them for information about the role of imagery as they write. Both L and J have spent more time on their second (untimed) essays. Without time constraint, they produced longer texts on untimed essay (149 vs. 170; 186 vs 284 words). However, despite a relatively long period of time spent writing an essay, these students neither described their images nor detailed them in their essays. Although their mental imagery generated an explosion of ideas for their writings, most visual thinking must merely be a means toward an end-pictures that writers spent in purchasing the right words or ideas.

The purpose of this study was to identify heuristically how abduction was used in a context of solving an earth-environmental problem. Thirty two groups of participants with different institutional backgrounds, i,e., inservice earth science teachers, preservice science teachers, and high school students, solved an open-ended earth-environmental problem and produced group texts in which their ways of solving the problem were written, The inferential processes in the texts were rearranged according to the syllogistic form of abduction and then analyzed iteratively so as to find thinking strategies used in the abductive reasoning. The result showed that abduction was employed in the process of solving the earth-environmental problem and that several thinking strategies were used for inferring rules from which abductive conclusions were drawn. The strategies found included data reconstruction, chained abduction, adapting novel information, model construction and manipulation, causal combination, elimination, case-based analogy, and existential strategy. It was suggested that abductive problems could be used to enhance students' thinking abilities and their understanding of the nature of earth science and earth-environmental problems.

In this study, we developed analogical experimental activities to foster scientific creativity in inquiry learning and applied them to 7th grade science-gifted students. The influences of inquiry learning-based analogical experiments were investigated with respect to the experimental design processes. We classified the patterns of experimental design processes by creative thinking processes and analyzed performance levels by the elements of experimental design processes. The students' experimental design processes were categorized into three kinds of patterns such as reinitiated motion, backward-divergent motion and stationary motion. Those belonging to the reinitiated motion performed precise experimental design from new perspectives by identifying the mapping in depth and considering the elements of experimental design processes. In the case of the backward-divergent motion, they shifted their positions to new directions, but the concreteness of experimental design was insufficient due to the lack of mapping or considering the elements. In the type of stationary motion, maintaining their previous positions, they showed less performance of experimental design without considering the elements sufficiently. Educational implication of these findings are discussed.
