The purpose of this study was to examine the relation between students' reflective thinking and providing the reading framework in implementation of argument-based inquiry using the Science Writing Heuristic (SWH) approach. Participants of this study were 60 $8^{th}$ grade students (two classes). One class (31 students) was assigned to an experimental group and the other class (29 students) was assigned to a comparative group. For the experimental group, five activities using the reading framework with SWH writing template were implemented, while three activities using the reading framework with the SWH writing template and two SWH activities without the reading framework were implemented for the comparative group. The result of this study showed that there was no significant difference in students' reflective thinking between both groups. However, results indicated that providing the reading framework with SWH approach facilitated students' reflective thinking. Therefore, the findings show that providing the reading framework consistently in the SWH approach was effective when it came to facilitating students' reflective thinking.

Understanding the equal sign is of great significance to the development of algebraic thinking. Given this importance, this study investigated in what ways a total of 695 students from second to sixth graders understand the equal sign. The results showed that students were successful in solving standard problems whereas they were poor at items demanding high relational thinking. It was noticeable that some of the students were based on computational thinking rather than relational understanding of the equal sign. The students had a difficulty both in understanding the structure of equations and in solving equations in non-standard problem contexts. They also had incomplete understanding of the equal sign. This paper is expected to explore the understanding of the equal sign by elementary school students in multiple problem contexts and to provide implications of how to promote students' understanding of the equal sign.

Korean 8-grade-students who participated in the ICILS 2018 were educated in the 2009 revised curriculum, where the 'Informatics' subject was an optional course in the regular curriculum. In order to closely analyze the ICILS 2018 results, it was necessary to take into account the situation in Korea that related educational experiences may differ among students. This study surveyed the students' educational experiences related to Informatics subject in the context of individual and schools. The average scores of computer and information literacy (CIL) and computational thinking (CT) of the ICILS 2018 were analyzed and compared by students' educational experiences. As a result, the average CT score of students who experienced the coding and programming education was higher than those who did not. Also, the more time students took the Informatics subject, the higher the average CT scores were. Based on these results, this study discussed implications in terms of expanding computational thinking education for elementary and secondary education.

The purpose of this paper is to analyze teaching-learning program which can be applied to mathematically gifted students in primary school, Our program is based on constructivist views on teaching and learning of mathematics. Mainly, we study the algorithmic thinking of mathematically gifted students in primary school in connection with the network problems; Eulerian graph problem, the minimum connector problem, and the shortest path problem, The above 3-subjects are not familiar with primary school mathematics, so that we adapt teaching-learning model based on the social constructivism. To achieve the purpose of this study, seventeen students in primary school participated in the study, and video type(observation) and student's mathematical note were used for collecting data while the students studied. The results of our study were summarized as follows: First, network problems based on teaching-learning model of constructivist views help students learn the algorithmic thinking. Second, the teaching-learning model based on constructivist views gives an opportunity of various mathematical thinking experience. Finally, the teaching-learning model based on constructivist views needs more the ability of teacher's research and the time of teaching for students than an ordinary teaching-learning model.

Reading ability has been widely considered as one of the basic skills that every student should be conversant with because higher level of thinking power can be acquired through reading. Reading education allows students to build correct way of thinking as well as foster critical thinking ability. However, it can be observed that reading education has not been well addressed accordingly in schools mainly because teachers have only limited amount of time and ability to cope with. In this paper, we developed a Web-based peer evaluation system for improving reading and writing ability so that students are allowed to exchange ideas freely on the Web after reading books as well as evaluate other students' writings, which would facilitate reflective thinking through the computer-mediated communication activities. Students become graders of other students' writings so that they are exposed to different opinions and ideas through which deeper thoughts can be obtained. The learner-centered learning activity instead of teacher-centered may benefit students as well as teachers and the system implementing this idea shows that both students' attitudes and preferences were improved as the result of applying the system to a local elementary school.

Most students have difficulties and negative perceptions about physics learning. Especially, it is difficult to understand the whole context by learning based on logical-scientific thinking which excludes narrative thinking. This study aims to develop a storytelling teaching-learning method using the narrative thinking in physics lessons for improving the difficulty of students of physics learning, For this purpose, a storytelling teaching-learning method that can improve scientific attitude and understand and change the concepts was developed through literature research. The following results were confirmed its effects to apply high school students and middle school students. First, the teaching-learning method using the storytelling for high school students with low interest in learning had a significant effect in science-related occupation, interest in science and science-related activities, criticism, openness, cooperation, and spontaneity. Second, the middle school students who are active in learning recognized that teaching and learning methods using storytelling helped to understand physics concepts. The storytelling teaching-learning method developed through this study is expected to stimulate students' interest and motivation in physics and to be useful for learning concepts by improving their scientific thinking skills.

Purpose: This study is a quasi-experimental study to investigate the effect of case-based learning (CBL) on critical thinking disposition, communication ability, problem solving ability and self-directed learning ability of nursing students in a pathophysiology course. Methods: The development of 3 CBL scenarios of pathophysiology were conducted by nursing faculties & clinical nurses before CBL began. Among the sophomore nursing students who were taking a pathophysiology course, the intervention group (n=43) was the nursing students who hope to participate in an extra-CBL program with usual pathophysiology lessons and the control group (n=36) was the nursing students who wanted to receive the usual pathophysiology lessons. The intervention group received additional CBL using 3 different scenarios for 1 hour per week during 4 weeks from May to June, 2016. Data were analyzed by a chi-square test, t-test and ANCOVA using SPSS WIN 18.0 Results: The mean score of critical thinking disposition (F=11.60, p=.001), communication ability (F=4.24, p=.043), and self-directed learning ability (F=4.75, p=.032) were significantly higher in intervention group than those in control group. But there was no significant difference between the two groups in problem solving ability (F=1.59, p=.211). Conclusions: The application of a CBL program during a pathophysiology course was effective in improving the critical thinking disposition, and the self-directed learning ability of sophomore nursing students.

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.

In this paper, we examine the effectiveness of calculation according to automation, which is one of Computational Thinking, by coding the conceptual process into Python language, focusing on the concept of divisibility in elementary school textbooks. The educational implications of these considerations are as follows. First, it is possible to make a field of learning that can revise the new mathematical concept through the opportunity to reinterpret the Conceptual Thinking learned in school mathematics from the perspective of Computational Thinking. Second, from the analysis of college students, it can be seen that many students do not have mathematical concepts in terms of efficiency of computation related to the divisibility. This phenomenon is a characteristic of the mathematics curriculum that emphasizes concepts. Therefore, it is necessary to study new mathematical concepts when considering the aspect of utilization. Third, all algorithms related to the concept of divisibility covered in elementary mathematics textbooks can be found to contain the notion of iteration in terms of automation, but little recursive activity can be found. Considering that recursive thinking is frequently used with repetitive thinking in terms of automation (in Computational Thinking), it is necessary to consider low level recursive activities at elementary school. Finally, it is necessary to think about mathematical Conceptual Thinking from the point of view of Computational Thinking, and conversely, to extract mathematical concepts from computer science's Computational Thinking.

In this study, we suggested the design thinking process that was possible to be introduced in science education and also examined the validity of the process in terms of group creativity. To do this, the design thinking process applicable to science education was selected from a variety of design thinking processes developed abroad, and then the process was modified and supplemented. We created the education program based on the developed design thinking process and applied it to high school students. The results revealed that we could offer the design thinking process through the five stages: 'understanding knowledge', 'empathy', 'sharing perspective', 'generating idea', and 'prototype'. With the results of the application of the program, we could confirm the relationship building and information seeking attributes in the understanding knowledge stage and the user-orientation, relationship building, and interpersonal understanding attributes in the empathy stage. We could also find the organization of the team attribute in the sharing perspective stage and the analytical strategic thinking attributes in the generating idea stage. Finally, the communication and analytical strategic thinking attributes in the prototype stage were confirmed. All of the key attributes of the group creativity found from skilled professionals were not confirmed from the students. However, we could ascertain the possibilities that the students should experience the process of group creativity and learn the relevant values through the developed design thinking process.
