The purpose of this study is to analyze the mathematical creativity and computational thinking of mathematically gifted elementary students through a convergence class using programming and to identify what it means to provide the convergence class using Python for the mathematical creativity and computational thinking of mathematically gifted elementary students. To this end, the content of the nine sessions of the Python-applied convergence programs were developed, exploratory and heuristic case study was conducted to observe and analyze the mathematical creativity and computational thinking of mathematically gifted elementary students. The subject of this study was a single group of sixteen students from the mathematics and science gifted class, and the content of the nine sessions of the Python convergence class was recorded on their tablets. Additional data was collected through audio recording, observation. In fact, in order to solve a given problem creatively, students not only naturally organized and formalized existing mathematical concepts, mathematical symbols, and programming instructions, but also showed divergent thinking to solve problems flexibly from various perspectives. In addition, students experienced abstraction, iterative thinking, and critical thinking through activities to remove unnecessary elements, extract key elements, analyze mathematical concepts, and decompose problems into small components, and math gifted students showed a sense of achievement and challenge.

This paper is designed to examine the effectiveness of Computational Thinking and programming awareness by designing and applying programming classes using Havruta. In the present society, where the Fourth Industrial Revolution was in full swing, the capacity to be equipped has changed, and the education has been changed accordingly. Programming education is logically capable of thinking and improves comprehensive problem solving skills. This direction of programming education allows us to get ideas for solving problems based on computing thoughts and to create our own creative results. However, because they require the grammar of the programming language and many additional abilities, they are not easy for learners, and individual differences in competencies make learning less immersive and interesting. In this paper, to solve the problems of the uniform programming class, this study is designed and applied to the class applying the Jewish traditional teaching method, Havruta's teaching method, to find out the effect of computing thinking and programming perception.

본 논문은 초등학교 3학년 학생들의 곱셈적 사고 수준을 조사하고, 이러한 사고가 비례 문제를 해결할 때 어떻게 발현되는지 분석한 연구이다. 구체적으로, 학생들이 곱셈 문제 해결과정에서 어떠한 사고를 보이는지, 각각의 사고 수준에 있는 학생들의 비례 해결 전략에 있어서의 차이점은 무엇인지 살펴보았다. 그 결과 덧셈에서 곱셈으로 가는 과도기적 사고 수준의 학생이 가장 높은 비율을 차지하고 있었으며, 사고 수준에 따라 비례문제 해결 과정에서 문제 해결 전략 및 오류 유형의 차이를 발견할 수 있었다. 이러한 연구 결과는 비례 추론의 기반이 되는 곱셈적 사고의 중요성을 강조하고, 이를 신장시키기 위한 곱셈 지도 방향에 대한 시사점을 드러낸다.

In the 11th AQCS(1997), the paper entitled 'Statistical Analysis of Baseball Records - Jinx and National Characteristics -' was presented by the same authors. At that time, the differences between Japanese characteristics and those of Europeans, using baseball data were discussed, mainly from the viewpoint of 'ways of thinking about chance cause and assignable cause.' In this paper, the authors described also on the same subject from the different viewpoint, 'ways of thinking at the design and development stage of new products', From this viewpoint, the difference also be found. It seems that the most significant difference between Japan and Germany exists in the field of aeroplanes design. The German ideas in the field were very unique, therefore the authors classified and named their ideas as: A) 'Quantitative analysis' type idea, and B) 'Chemical synthetic' type idea. The former concept is composed of two ways of thinking: a) All parts essential for just flying must be used, but b) All other parts shall be rejected, as far as possible. The latter concept is that, the all additional parts necessary for the development of the above 'purified' original product should be added respectively, depending on the requests of customers. These ideas are outlined using the actual examples of German aeroplane.

The purpose of value analysis is to assist each to approach nearer enough to this goal to provide substantial competitive and profit advantages. It provides planned and disciplined thought and act ion which hel ps identify unnecessary cost throughout the product or process cycle. Value analysis is a precise, disciplined, one-purpose thinking process. Its one purpose is to retain all the performance and aesthetic factors which now exist In the product, process or services, which the customer wants and is willing to pay for : and through disciplined thinking procedures, to put together Practical alternatives which will accomplish them at still lower cost. Value in a product or service is the reward for appropriate performance and appropriate cost Value analysis must therefore employ techniques which will sensitize any "lacking" area so that the need can be identified and satisfied. As the business begins to see the benefit of the activity, additional value analysts consultants may be added. This will provide more penetration in the three identified areas, of top managers group, individual value analysis consultants and senior member who organizes value analysis work, and besides, additional abilities will be secured.e secured.

Purpose: The purpose of this study was to investigate the effects of preclinical clinical performance examination (CPX) on nursing students' confidence in their nursing skills and critical thinking competence. Methods: The design of this research was one-group pretest-posttest, and the participants were 112 nursing students. The preclinical CPX consisted of a clinical examination, patient-nurse relationship, oral test of related knowledge, written test of the nursing process, and debriefing using comprehensive scenarios based on real patient cases. The confidence of nursing skills consisted of an 8-item NRS and the critical thinking competence consisted of a 12-item 4-point scale developed by researchers and measured in both the pretest and posttest. The collected data were analyzed using paired t-tests, ANOVA, and Pearson correlation coefficients. Results: The score for confidence in nursing skills (t=10.60, p<.001) and that for critical thinking competence (t=7.03, p<.001) increased significantly after preclinical CPX. Conclusion: This study showed that preclinical CPX was effective in improving nursing students' confidence in their nursing skills and critical thinking competence. Therefore, preclinical CPX is expected to be utilized in nursing practice education. Additional studies including those on control groups are recommended to compare differences between the preclinical CPX group and control group.

소프트웨어교육의 도구로서 블록형 교육용 프로그래밍 언어(EPL)는 무료로 이용할 수 있고, 피지컬 컴퓨팅은 현실세계와 컴퓨팅 환경을 연결시켜줌으로써 실생활 문제 해결이라는 목표에 더욱 가깝게 다가갈 수 있도록 해주기 때문에, 특히 초등학교 단계에서 학생들이 직관적으로 이해하기 쉬우며 알고리즘적 사고를 향상시키기 때문에 많이 이용되고 있다. 본 연구에서는 초등학생도 회로지식 없이 쉽게 접할 수 있고 가격적인 측면에서도 큰 부담이 가지 않는 엔트리와 센서보드를 활용한 EPL 및 피지컬 컴퓨팅 교육과정을 제시하고, 초등학교 6학년 학생을 대상으로 12차시의 EPL 교육과정과 8차시의 피지컬 컴퓨팅 교육과정을 개발하고 적용하였다. 본 연구의 결과 EPL 교육과정을 적용한 집단과 피지컬 컴퓨팅 교육과정을 추가로 적용한 집단 모두 학생들의 컴퓨팅 사고력 향상에 유의미한 효과가 있었으며, 피지컬 컴퓨팅 교육과정을 추가로 적용한 집단에서 컴퓨팅 사고력 요소의 자료표현, 수행 및 검증, 일반화에서 유의하게 더 큰 향상을 보였다.

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.
