This paper aims to deeply investigate the interactive patterns between a robot teacher and a participating gifted student who assembled GoGo Bumper car and controlled it with GoGo Monitor commands. Two days of classroom activities for the GoGo Bumper car project were videotaped between July 29 and 30 in 2013. Extra video-based recall interviews were also conducted three times between Nov 2013 and Jan 2014. The qualitative analysis of video data, GoGo Monitor codes and interview data revealed several unfolding patterns of computational thinking. The participating student while interacting with a robot teacher often contemplated and coded on his own ways as he worked with GoGo board testing and assembling a GoGo Bumper car. The overall process of coding and testing his own ideas by finding out relevant commands and arranging them attuned to his computational strategies seems to be cyclic.

Background: This study was conducted to verify the effectiveness of geriatric dental hygiene education by developing and operating an industrial demand-based curriculum for geriatric dental hygiene. Methods: Wilcoxon signed rank test was performed to verify the before-and-after differences in major competency achievement, geriatric dental hygiene awareness, and class satisfaction according to industrial demandbased field-oriented practical education, and Spearman's correlation analysis was performed to confirm the association between each factor(p<0.05). Results: In the case of major competency achievement, 'communication competence with the older adults' was significantly improved(p=0.031) after conducting industrial demand-based field-oriented practical training. Conclusion: It is believed that the understanding of the older adults and the practical skills for oral care of the older adults can be further developed when the learners are provided with a practical curriculum that can be used in the geriatric industrial field.

The purpose of this study is to investigate the effect of flipped learning-based health assessment education on academic achievement of nursing students. The subjects of the study included nursing students attending second year at university. For 10 weeks, the experimental group was exposed to flipped learning-based classes, and the control group was provided with traditional lectures and team learning-based classes. In the intermediate evaluation, the knowledge and performance scores of the experimental group and the control group were statistically significant, and in the final evaluation, the knowledge and performance scores of the experimental group and the control group were statistically significant. The integrated knowledge score, evaluated three times after the end of the training, was higher in the experimental group than in the control group. These results suggest that flipped learning is an effective teaching and learning method for improving knowledge and performance of nursing students. Therefore, the application of flipped learning in various nursing education areas should be studied.

The purpose of this research is to identify how industrial highschool try to organize and apply NCS based curriculuma, to find out problems, and to suggest what the task for the sustained development and growth under the NCS based industrial highschool curriculum In order to identify actual situation and problems, when a industrial highschool organize and apply NCS based curriculum, we suveyed NCS based curriculum that 583 specialized, Meister highschools organize. The problems to identify through analysis about NCS based curriculum that schools organize are the followings First, schools' NCS based curriculum is set up too much comprehensive type for training human resources. Second, carreer path of students is not considered by schools' NCS based curriculum. Third, yearly plan for schools' NCS based curriculum is not balanced to raise working experience skill among each grades. Forth, schools are not ready to use NCS learning module. Task to solve these problems are the following. First, schools' curriculum have to be organized on the basis of NCS's purpose. Second, teachers have to restructure the NCS learning module in order to go up availability of NCS learning module.

With the advent of the Fourth Industrial Revolution and changes in the educational environment, team-based assignments are increasing in university classes. Effective team formation in team-based class is an important issue that affects students' satisfaction and the effectiveness of education. However, previous studies mostly focused on post analysis on the results of team formation, which makes it difficult to use them in actual classes. In this paper, we present a mathematical model of how to create a balanced team that reflects students' abilities and other characteristics. Characteristic values for assignment may be scores, such as students' proficiency, binary values such as gender, and multi-values, such as grade or department. This problem is a type of equitable partitioning problem, which takes the form of 0-1 integer programming, and the objective function is linear or nonlinear, depending on how balance is achieved. The basic model or the extended model presented can be applied to the situation where teams are balanced in consideration of various factors in actual class.

The purpose of this study is to develop elementary school math classes for the gifted and talented with a focus on social issues to investigate the possibility of character education through specialized subject classes. As suggested in the goals of the math education for social justice, which provide the fundamental theoretical basis, through mathematics activities with a theme of social issues, mathematically gifted and talented young students can critically perceive social issues, express a sense of mathematical and critical agency throughout the course and develop a willingness and mindset to contribute to social progress. In particular, the concept of Figured Worlds and agency is applied to this study to explain the concept of elementary math classes for the gifted and talented with a focus on social issues. The concept is also used as the theoretical framework for the design and analysis of the curriculum. Figured Worlds is defined as the actual world composed of social and cultural elements (Holland et al., 1998) and can be described as the framework used by the individual or the social structure to perceive and interpret their surroundings. Agency refers to the power of practice that allows one to perceive the potential for change within the Figured Worlds that he is a part of and to change the existing Figured Worlds. This study sees as its purpose the fostering of young talent that has the agency to critically perceive the social structure or Figured Worlds through math classes with a theme of social issues, and thus become a social capital that can contribute to social progress.
