Purpose: The purpose of this study was to analyze the topic trend of domestic simulation nursing education research using text network analysis(TNA). Methods: This study was conducted in four steps. TNA was performed using the NetMiner (version 4.4.1) program. Firstly, 245 articles from 4 databases (RISS, KCI, KISS, DBpia) published from 2008 to 2018, were collected. Secondly, keyword-forms were unified and representative words were selected. Thirdly, co-occurrence matrices of keywords with a frequency of 2 or higher were generated. Finally, social network-related measures-indices of degree centrality and betweenness centrality-were obtained. The topic trend over time was visualized as a sociogram and presented. Results: 178 author keywords were extracted. Keywords with high degree centrality were "Nursing student", "Clinical competency", "Knowledge", "Critical thinking", "Communication", and "Problem-solving ability." Keywords with high betweenness centrality were "CPR", "Knowledge", "Attitude", "Self-efficacy", "Performance ability", and "Nurse." Over time, the topic trends on simulation nursing education have diversified. For example, topics such as "Neonatal nursing", "Obstetric nursing", "Pediatric nursing", "Blood transfusion", "Community visit nursing", and "Core basic nursing skill" appeared. The core-topics that emerged only recently (2017-2018) were "High-fidelity", "Heart arrest", "Clinical judgment", "Reflection", "Core basic nursing skill." Conclusion: Although simulation nursing education research has been increasing, it is necessary to continue studies on integrated simulation learning designs based on various nursing settings. Additionally, in simulation nursing education, research is required not only on learner-centered educational outcomes, but also factors that influence educational outcomes from the perspective of the instructors.

노티싱은 교사가 교수학습 맥락에서 무엇에 주의를 기울이는지, 그것을 어떻게 해석하고 반응해야 하는지 결정하는 것을 의미한다. 노티싱을 분석하여 교육 설계 및 실행의 주체인 교사의 수업설계, 실행, 반성의 전반적 특성을 이해할 수 있으며 이는 교사 역량 강화를 위한 교사교육 설계의 기초자료로 활용할 수 있다. 이에 이 연구에서는 수업설계와 시연 후의 성찰 과정에서 나타나는 초등 예비교사의 노티싱 특성을 분석하였다. 이를 위하여 강원도 소재 교육대학에 재학 중인 초등 예비교사 106명이 온도에 따른 기체의 부피 변화 개념을 다루는 과학수업의 시연 후에 작성한 수업 성찰지를 분석하였다. '주체', '수업 단계', '주제', '초점', '견지'의 다섯 가지 차원으로 이루어진 노티싱 분석틀을 설계한 후 이를 활용하여 각 차원의 구성요소별 빈도와 비율을 도출하였다. 또한 '수업 단계'와 '주제'에 따른 '초점'의 빈도와 비율을 분석하였다. 연구 결과 '주체' 차원에서는 '교사와 학생'을 동시에 주목한 빈도가 가장 높았으며, '수업 단계' 차원에서는 '탐구 활동'의 빈도가 가장 높았다. '주제' 차원에서는 '수업전략에 따른 수업설계'가 가장 빈번하게 나타났으며 '초점' 차원에서는 수업의 목표이자 학생이 달성해야 할 역량을 특정하지 않은 경우가 가장 많았다. '견지' 차원에서는 '기술'이 가장 높은 빈도로 나타났다. '수업 단계'와 '주제'에 따라 '초점'이 어떻게 달라지는지 분석한 결과 차원의 구성요소별로 특징적인 초점이 나타난 것을 알 수 있었다. 연구 결과를 토대로 예비교사의 노티싱 특성이 교사교육의 설계 및 운영에 갖는 시사점을 논의하였다.

Division of fractions is always a difficult topic for primary school students. Most of the presentations in teaching the topic in textbooks are procedural, asking students to invert the second fraction and multiply it with the first one, that is, $$\frac{a}{b}{\div}\frac{c}{d}=\frac{a}{b}{\times}\frac{d}{c}$$. Such procedural approach in teaching diminishes both the understanding of structure in mathematics and the interest in learning the subject. This paper discussed the formulation of teaching the division of fractions, which based on research lessons in some primary five classrooms. The formulated lessons started with an analogy to division of integers and working with division of fractions with equal denominators and then extended to division of fractions in general. It is found that the using of analogy helps students to invent their procedure in working the division problem. Some procedures found by students are discussed, with the focus on the development of their invention and mathematical thinking.

Examining ways to interact with students in small groups is an important topic for researchers to understand. Existing studies pertaining to the topic have not shed light on knowing why teachers interact with students in small groups the way they do. Given that teacher identity shapes teaching practices, this study explores how teacher identity shapes teachers' interaction with students in small groups. Working with two beginning teachers, I conducted four interviews to collect the data related to reasons behind their interactions with students in small groups in the interview. I analyzed the interview transcripts using a thematic analysis. I found that one teacher's teacher identity was related to her personal experiences as a child and a learner and another teacher's teacher identity was related to her view of teachers' roles as a teacher. I provide discussion and implications of this study.

There is a more urgent call for educational methods of machine learning in medical education, and therefore, new approaches of teaching and researching machine learning in medicine are needed. This paper presents a case using machine learning through text analysis. Topic modeling of news articles with the keyword 'asbestos' were examined. Two hypotheses were tested using this method, and the process of machine learning of texts is illustrated through this example. Using an automated text analysis method, all the news articles published from January 1, 1990 to November 15, 2016 in South Korea which included 'asbestos' in the title and the body were collected by web scraping. Differences in topics were analyzed by structured topic modelling (STM) and compared by press companies and periods. More articles were found in liberal media outlets. Differences were found in the number and types of topics in the articles according to the partisanship and period. STM showed that the conservative press views asbestos as a personal problem, while the progressive press views asbestos as a social problem. A divergence in the perspective for emphasizing the issues of asbestos between the conservative press and progressive press was also found. Social perspective influences the main topics of news stories. Thus, the patients' uneasiness and pain are not presented by both sources of media. In addition, topics differ between news media sources based on partisanship, and therefore cause divergence in readers' framing. The method of text analysis and its strengths and weaknesses are explained, and an application for the teaching and researching of machine learning in medical education using the methodology of text analysis is considered. An educational method of machine learning in medical education is urgent for future generations.

The Engineering school of Tohoku University has been offering a Team-based Engineering Design Course to its first year students since 1996 in order to increase the level of both motivation and interest in engineering. Freshmen are required to select one of approximately 150 topics and do some research on this topic. This course also provides opportunities for students to participate in exchange programs with the University of Washington (UW) and the University of Science and Technology Beijing (USTB). In the Tohoku-UW exchange program, which began in 1999, between 10 and 25 students of Tohoku visit the UW annually to present the results of the subjects the school has appointed in advance in the Team-based Engineering Design Course. In the Tohoku-USTB exchange program, which began in 2007, about 15 students from each university participate in a one day meeting organized by the students themselves. They give a presentation on either the results of the subject they selected in the course, or on an engineering related topic both groups have agreed to in advance. In this paper, a detailed history, the objectives, a schedule and the budget in these unique exchange programs is introduced together with an outline of the course and its contribution to the engineering design education.
