The purpose of this study is to analyze the conceptual simulation observed when students are thinking about the causes of the seasonal change, identifying how students come up with the explanation. For this study, a framework for conceptual simulation process and strategy based on literary research was developed and its validity was proved by four experts in the field of science education. The results were as in the following: First, through the process of explaining the causes for seasonal change, students usually base their explanation on perceptual experience learned from model experiments from a science class. Besides, construct of thought experiment using the familiar object or analogize of the familiar perceptual experience. These all contributed to on explanation firmly. Second, errors from mental simulation were found in the statement of initial representation and running imagistic simulation. It happened when statement of initial representation is not in a complete and secure state or when participants think of an inappropriate situation during running imagistic simulation. Third, the study identified that the use of strategies like 'removal' and 'replace' was shown to enhance the effects of conceptual simulation particularly in regard with solar attitude at meridian passage.

This study was conducted to examine the effects of simulation-based education on the clinical reasoning competence, clinical competence, and satisfaction with simulation experience (SSE). The research design was one group pretest-posttest. Study participants were 89 third-year nursing students from C University in G city, who were engaged the simulation-based education for eight weeks from August to October 2019. Learning scenario titles were blood transfusion reaction patient care with postoperative total hip replacement, hypoglycemia patient care with diabetes mellitus, and hyperkalemia patient care with liver cirrhosis. The data were analyzed by paired t-test using SPSS Win 23.0 program. After applying simulation-based education, nursing students' clinical reasoning competence (t=-17.082, p<.001) and clinical competence(t=-18.40, p<.001) improved significantly. SSE score was 4.65 out of 5 points. The results indicate that the simulation-based education in this study gave the students the experience of providing qualified and secure nursing care under conditions similar to those in the real clinical field. To improve the clinical reasoning competence and clinical competence of nursing students, various cases scenarios are developed and simulation-based education should be applied to more subjects in the nursing curriculum.

Recently, the distance education has been rapidly proliferated with the rapid growth of the Internet and high speed networks. There has been relatively much research with regard to online lecture (teaching and studying) tools for the distance education, compared to the virtual laboratory tools (for self-study and experiments). In this paper, we design and implement a web-based simulation tool, named as SimDraw, for the virtual laboratory in the distance education. To apply the web-based simulation technology into the distance education, some requirements should be met; firstly, the user interface of the simulation should be very easy for students. Secondly, the simulation should be very portable to be run on various computer systems of remote students. Finally, the simulation program on remote computers should be very thin so that students can easily install the program onto their computers. To meet these requirements, SimDraw adopts the client/server architecture; the client program contains only model development and animation functions so that no installation of a client program onto student's system is required, and it can be implemented by a Java applet in Web browsers. The server program supports client programs by offering the functions such as remote compiling, model storing, library management, and user management. For the evaluation of SimDraw, we show the simulation process using the example experimentation of the RIP(Routing Information Protocol) Internet routing protocol.

Purpose - According to the importance of business simulation learning as a new type of business learning tool, this study reviews the dimensions of business education and a brief history of business education simulation. At the end Capsim strategic management simulation program is introduce with its feature. Research design, data, and methodology - This study has been analyzed in a way that reviews at previous literature on simulation learning and looks at examples and features of Capsim simulation, online business simulation tools which has been used in the global market. Result - Capsim simulations are designed to offer focused opportunities for deep practice. That's why they are often more effective than passive tools such as textbooks, videos, or lectures. By the way, 'deep practice' is very different from 'ordinary practice'. After commuters who drive to school or work can accumulate thousands of hours of driving, but that doesn't make them expert drivers. The key to deep practice is self-awareness. That is, paying attention to what you are doing well and not so well. This is so important to learn that scientists use a specific term for it: 'metacognition', or thinking about the way you think and learn. Conclusion - The use of business simulation learning, such as Capsim, which is a given case, can create similar local systems by potentially engaging a large number of users in the virtual market. It could also be used as an individual to complete business training for students and those who are active in the business field of business.

This study aimed to determine the effects of simulation-based education in diabetic patient care to nursing students on their level of diabetic knowledge, clinical nursing competence, practicum satisfaction and communicative competence. The pre-post test were conducted to compare the differences in diabetic knowledge, clinical nursing competence, practicum satisfaction and communicative competence. The research data for the subject of study was collected from October 21 to November 1, 2013 in 3rd grade 75 nursing students. The student who had received the simulation-based education, did show significant increase in diabetic knowledge(t=-9.684, p<.001), clinical nursing competence(t=-4.173, p<.001), and communicative competence(t=-7.685, p<.001) than before. But, there was no significant different in the practicum satisfaction(t=-1.144, p=.256). Based on the above results, simulation-based education can enhance the nursing knowledge, clinical performance and communication ability of the subjects and can be applied to various education courses.

The importance of software in the engineering field is increasing day by day, so the utilization and understanding of the simulation software in the engineering design stage has become the core competence of the engineer. This study presents a new software education method for multiple systems in the field of mechanical engineering using a workflow execution environment as a sub-module of a computational platform (called EDISON platform) that can incorporate in-house software tools developed by many simulation tool developers. It can execute not only individual software tools such as fluid flow, structure, optimal design, but also conduct connective executions of multiple software tools. Based on this simulation environment, a methodology was proposed that can be applied to convergence types of engineering educations. By properly using this methodology, it is expected that beginning engineers could encourage their specialties understanding the big pictures of the analysis processes.
