This study analyzed the difficulties of middle school students in computer simulation of the law of large numbers through eye movement analysis. Some students did not attend to the simulation results and could not make meaningful inferences. It is observed that students keep the existing concept even though they observe the simulation results which are inconsistent with the misconceptions they have. Since probabilistic intuition influence student's thinking very strongly, it is necessary to design a task that allows students to clearly recognize the difference between their erroneous intuitions and simulation results. In addition, we could confirm through eye movements analysis that students could not make meaningful observations and inferences if too much reasoning was needed even though the simulation included a rich context. It is necessary to use visual representations such as graphs to provide immediate feedback to students, to encourage students to attend to the results in a certain intentional way to discover the underlying mathematical structure rather than simply presenting experimental data. Some students focused their attention on the visually salient feature of the experimental results and have made incorrect conclusion. The simulation should be designed so that the patterns of the experimental results that the student must discover are not visually distorted and allow the students to perform a sufficient number of simulations. Based on the results of this study, we suggested that cumulative relative frequency graph showing multiple results at the same time, and the term 'generally tends to get closer' should be used in learning of the law of large numbers. In addition, it was confirmed that eye-tracking method is a useful tool for analyzing interaction in technology-based probabilistic learning.

This study aimed to examine the effects of simulation-based neonatal nursing care education on the communication competence, self-efficacy, clinical competency. A one-group pre-and post test design was used. A total of 122 students participate. Data was collected from May 3 to June 4, 2021, using self-report questionnaires only for students who understood the purpose of the study and gave written consent to participate. For the simulation-based neonatal nursing care education, a total of three steps of preparation for scenario implementation, scenario implementation, and debriefing were applied in groups of 3-4 people of 4.5 hours. As a result of this study, it was found that the simulation-based neonatal nursing care education had statistically significant improvement in communication competence, self-efficacy, clinical competency. Through the results of this study, it was confirmed that simulation-based education in the nursing care of children can be an effective teaching-learning method that can supplement the observation-oriented clinical practice of child nursing for nursing students.

Purpose: The purpose of this study was to identify the effects simulation-based education combined team-based learning (SBE combined TBL) compared to simulation-based education (SBE) on undergraduate nursing students. Methods: A non-equivalent control group design with pre-and posttest measures was used. The participants in the study were 181 students. The SBE combined TBL group consisted of 84 senior students in 2013, and the SBE group consisted of 97 seniors in 2014. Collected data were analyzed using chi-square, independent t-test and ANCOVA with the statistical package SPSS 22.0 for Windows. Results: There was a significant improvement in communication skills, nursing performance confidence, team efficacy, and team performance scores in the SBE combined TBL group compared to the SBE group (t=2.45, p=.015; F=4.30, p=.040; t=3.06, p=.003; t=8.77, p<.001). However, there was no statistically significant difference in self-directed learning between the groups. Conclusion: SBE combined TBL compared to SBE is an effective teaching and learning method to enhance various positive educational outcomes for nursing students. Therefore, we suggest that future studies investigate the development of an integrated course in which team-based learning is applied to theoretical sessions and simulation-based training.

Purpose: This was a cross-sectional descriptive study in which an exploration was done of how nursing students perceive debriefing and what they think are the most effective debriefing methods for simulation-based nursing education. Methods: A convenience sample of 296 sophomore, junior and senior nursing students from three universities and who had attended simulation classes participated in this study. Survey data garnered was analyzed using descriptive analysis and $x^2$ test. Results: A high majority of the participants (98.3%) saw debriefing as "learning from mistakes", while 62.8% considered it more important than simulations/scenarios. They also perceived debriefing to be effective when they analyzed their colleagues' and their own performances and received feedback. Sophomore students preferred writing a reflection paper as an effective debriefing method compared to junior and senior students. Conclusion: The study findings indicate that debriefing is an important component of simulation-based education and should be considered part of the teaching strategies with debriefing methods dependent on themes and scenarios and what is needed to achieve learning outcomes.

The main purpose of the Boolean equivalence problem is to verify that two Boolean expressions have the same functionality. Simulation has been extensively used as the standard method for the equivalence problem. Obviously, the number of tests required to perform a satisfactory coverage grows exponentially with the number of input variables. However, formal methods as opposed to simulation are getting more attention from the community. We propose a new algorithm called the Cover-Merge Algorithm based on a derivational method using the concept of cover and merge for the equivalence problem and investigate its theoretical aspects. Because of the difficulty of the problem, we emphasize simplification techniques in order to reduce the search space or problem size. Heuristics based on types of merges are developed to speed up the derivation process by allowing simplifications. In comparison with widely used technique called Binary Decision Diagram or BDD, the algorithm proposed outperforms BDD in nearly all cases of input including standard benchmark problems.

Comparative analyses of a shield building subjected to a large commercial aircraft impact between decoupling method and coupling method are performed in this paper. The decoupling method is applying impact force time-history curves on impact area of the shield building to study impact damage effects on structure. The coupling method is using a model including aircraft and shield building to perform simulation of the entire impact process. Impact force time-history curves of the fuselage, wing and engine and their total impact force time-history curve are obtained by the entire aircraft normally impacting the rigid wall. Taking aircraft structure and impact progress into account some loading areas are determined to perform some comparative analyses between decoupling method and coupling method, the calculation results including displacement, plastic strain of concrete and stress of steel plate in impact area are given. If the loading area is determined unreasonably, it will be difficult to assess impact damage of impact area even though the accurate impact force of each part of aircraft obtained already. The coupling method presented at last in this paper can more reasonably evaluate the dynamic response of the shield building than the decoupling methods used in the current nuclear engineering design.

This study is a qualitative research attempted to understand meaning and essential structure of experience of nursing students who received simulation training and video watching education. The collected data were analyzed using the Colaizzi method among the phenomenological methods. The results of the study showed that the simulation practice was divided into three categories (experience of clinical nursing in advance, benefit of simulation exercise, limitation of simulation exercise) and 14 themes. Video watching education was derived from three categories (convenience of education, increase of educational effect, lack of knowledge transfer) and 6 themes. In conclusion, it is suggested that the simulation training and the video watching education should be reflected the results of this study in order to apply to the nursing curriculum effectively.

Purpose: The purpose of this study was to identify the effect of a simulation-based practice on clinical performance and problem solving processes for nursing students. Method: The study used a one group pre-post test design. Students experienced a simulation-based practice that included team base learning, skill training, taking a high-fidelity simulation with SimMan 3G, and also being debriefed for 12 weeks (August 2010 to December 2010). The pre-test and post-test were conducted to compare the differences in knowledge, clinical nursing skills, and problem solving processes. Result: After students had received the simulation-based practice, they showed statistically significant higher knowledge (t=14.73, p<.001) and clinical nursing skills (t=15.47, p<.001) than before. However, there was no significant difference in the problem solving process score (t=1.53, p=.127). Conclusion: This study showed that knowledge and clinical nursing skills were significantly improved by the simulation-based practice. Further research would be required to identify how the problem solving process that uses simulation-based practice could be developed further.
