Self-Regulated Learning Strategy is a kind of learning strategy that learners could choose and apply metacognitive, cognitive, motivational, and behavioral strategy autonomically and could take an active part in the classes. The purpose of the study was to identify aspects of self-regulated learning strategy with mathematical journal writing. Mathematical journal was composed of 13 questions and each of factor had 1~2 questions. The results of the study have revealed that metacognitive strategies were identified as setting up learning goals, seeking problem solving strategies, reflective thinking and providing examples. Cognitive strategy was identified as understanding the structure among ideas, sequential ranking and key ideas. Motivational strategy was identified as satisfaction and anxiety for studies, confidence and frustration for next studies. There are implications for mathematics education that self-regulated learning strategy can be improved with mathematical journal writing and help students to study mathematics efficiently and successfully.

The present study tested the hypothesis that maturation of the prefrontal lobes is a crucial factor determining the performance of scientific reasoning tasks, Functions of the prefrontal lobes, such as activating relevant information, sequential planning and monitoring, and inhibiting irrelevant information, are related thinking patterns with scientific reasoning. Therefore, we inferred the idea that the prefrontal lobes play an important role in scientific reasoning. To test the hypothesis. the present study investigated a prefrontal lobe patient's task solving procedures in scientific reasoning tasks and the correlation and regression analysis between a test of prefrontal lobe function and two scientific reasoning tasks, The perseverative errors in the Wisconsin Card Sorting Test(WCST) was used as a measure of the prefrontal lobe function, The Melinark Type Task and the Classroom Test of Scientific Reasoning were used as measures of scientific reasoning abilities. Ages and Group Embedded Figure Test were also used as measures of two alternative hypotheses, general maturation and field independency respectively. The prefrontal lobe patient showed a crucial deficiency in solving scientific reasoning tasks. In the tasks, the patient could not used the reasoning of If... and... then... therefore pattern. In correlation study, the perseveration errors of the WCST showed a significantly negative correlation with two scientific reasoning tasks. Multiple regression study also showed that the perseveration errors measured as a function of the prefrontal lobes have more contribution to scientific reasoning ability than contributions of alternative hypotheses. Therefore, the present study supported the hypothesis that prefrontal lobes play a crucial role in scientific reasoning ability, What function of the prefrontal lobes do play crucial role in scientific reasoning? The present study provided an explanation for the question, which inhibiting ability of the prefrontal lobes is responsible for the scientific reasoning ability, in a part at least. That is, perseverative tendency in task-solving procedures causes a deficiency of an ability to inhibit the wrong information to solve a task. The present study provided a possibility of neuropsychological approach in science education research. The present study also showed an importance of the prefrontal lobe development in the performance of scientific reasoning task.

The purpose of this study is to develop a Goldberg device-based software(SW) convergence Education tool. The 2015 revised curriculum emphasizes convergence with various subjects for effective SW education. In particular, physics is often used as a material for SW convergence education because it is closely related to computational thinking such as sequential movement, quantification of energy and simulation. In this study, we developed an educational program based on the Goldberg device that utilizes physical knowledge, concepts and manipulation. In order to verify the effectiveness of the program, the survey questions were developed through Delphi verification and a basic satisfaction survey was conducted based on this. As a result, the developed program can be effectively used as a program for SW convergence education.

Purpose: This study aimed to identify relationships among knowledge and skills about suicide prevention, attitudes toward suicide, and burnout of suicide prevention work of nurses at mental health welfare centers. Methods: An explanatory sequential mixed-method research was conducted. For the quantitative study, the subjects (nurses) were 133 nurses executing suicide prevention work. The data were analyzed using the SPSS 25.0 program. For the qualitative research, 13 nurses with high burnout scores were interviewed. The data were analyzed using theme analysis method. Results: Quantitative results showed the average burnout of suicide prevention work was 54.62 ± 12.51. The burnout of suicide prevention work had significant correlations with attitudes toward suicide (r = .30, p < .001) and suicide prevention skills (r = - .18, p = .037). Qualitative results showed six themes related to burnout of suicide prevention work. They were 'feeling a lack of confidence in one's suicide counselling skills', 'feeling of the limits of one's ability to cope with a suicide crisis', 'feeling regret for not being able to help the clients', 'being over-empathetic to the clients', 'Not being able to understand the clients because the subjects (nurses) opposes committing suicide', and 'thinking that the suicidal thoughts of suicide attempters do not improve'. Conclusion: To reduce burnout of nurses' suicide prevention work at mental health welfare centers, there is a need to develop an educational program considering nurses' attitudes toward suicide and one to enhance their confidence in suicide prevention skills.

Recently there are growing needs and demand to enhance 'Unity of knowledge' as the concept of "Creating new value through integration and convergence" is developing rapidly in many different areas in the society. This also has significant implication to education. Especially, it requires paradigm shift in terms of required capabilities and qualifications for the students with science major. To accommodate this trend, Natural Sciences and Engineering's College has been increasing convergence education which focus on cultivating creative and cooperative learning capabilities as well as acquiring fundamental knowledge of individual majors. However, convergence education developed and implemented by Sciences college or liberal education so far has been mechanical combination of knowledge from different academic fields - not effectively integrated and interdisciplinary education. Given this situation, this research is to develop and propose a "convergence education program based on the development of scientific and cultural contents" as an education tool to enhance capabilities to apply and re-create integrated knowledge as well as acquire and learn existing knowledge. Education program developed in this research aims to achieve two different and sequential capabilities. First is to understand 'Science and Technology' and 'Cultural Archetype' which would be essential and useful to create cultural contents. Second is to develop capabilities to convert this understanding into cultural contents - a storytelling capability. This education program is differentiated in that it defines cultural contents as a medium to converge and integrate science and technology and humanities. By leveraging the concept of cultural content and storytelling, this education program would be able to overcome restrictions of existing interdisciplinary approach. Also, this program would encourage students to try in-depth research and new applications, and develop logical and creative thinking.

This study conducts a comprehensive analysis of the curricular progression of the concepts and learning sequences of 'lines', specifically, 'line segments', 'straight lines', and 'rays', at the elementary school level. By examining mathematics curricula and textbooks, spanning from 2nd to 7th and 2007, 2009, 2015, and up to 2022 revised version, the study investigates the timing and methods of introducing these essential geometric concepts. It also explores the sequential delivery of instruction and the key focal points of pedagogy. Through the analysis of shifts in the timing and definitions, it becomes evident that these concepts of lines have predominantly been integrated as integral components of two-dimensional plane figures. This includes their role in defining the sides of polygons and the angles formed by lines. This perspective underscores the importance of providing ample opportunities for students to explore these basic geometric entities. Furthermore, the definitions of line segments, straight lines, and rays, their interrelations with points, and the relationships established between different types of lines significantly influence the development of these core concepts. Lastly, the study emphasizes the significance of introducing fundamental mathematical concepts, such as the notion of straight lines as the shortest distance in line segments and the concept of lines extending infinitely (infiniteness) in straight lines and rays. These ideas serve as foundational elements of mathematical thinking, emphasizing the necessity for students to grasp concretely these concepts through visualization and experiences in their daily surroundings. This progression aligns with a shift towards the comprehension of Euclidean geometry. This research suggests a comprehensive reassessment of how line concepts are introduced and taught, with a particular focus on connecting real-life exploratory experiences to the foundational principles of geometry, thereby enhancing the quality of mathematics education.

Object：This study examined the diagnostic validity of the K-ABC and the K-LDES for identifying the cognitive deficits and the learning difficulty of children with learning disorder and to diagnose the learning disorder. Method：The clinical group consisted of 15 children with learning disorder or attention deficit hyperactivity disorder accompanying learning problem(LP) and 14 children with attention deficit hyperactivity disorder. They were diagnosed either learning disorder or attention deficit hyperactivity disorder based on DSM-IV criteria by child psychiatrists and clinical psychologists visiting Seoul National University Children’s Hospital. The normal group was composed of 15 children be going to an elementary school. All groups were between the age of 7 and 12. The K-ABC was administered to the clinical and the normal group. The K-LDES was also administered to mothers of all groups. Result：There were no significant differences on sequential, simultaneous, mental processing subscales of the K-ABC in three groups. However, The LP group showed slightly lower scores on Achievement scale and significant low scores on Reading/Decoding than the other groups. On K-LDES, LP group showed significant low scores on Listing, Thinking, Reading, Writing, Spelling, Mathematical calculation, Learning quotient(LQ) than the other groups. Also there were significant correlations between K-ABC and K-LDES subscales. Conclusion：The result of present study showed that the K-ABC and the K-LDES are a valid and effective instruments for evaluating and diagnose the learning disorder.
