In this study, we analyzed the types of rebuttals in the argument structure of learning contents in lesson plans constructed by Earth science preservice teachers, and then we explored examples of how they responded to resolving the rebuttal. As a result of analyzing preservice teachers' assignments, discussions, and interviews collected during a total of 20 hours of classes and group discussions for 5 weeks, all 5 types of rebuttals suggested by Verheij (2005) were identified. Through the data analysis, a total of 18 rebuttal cases derived, and these cases were classified into 3 types according to how preservice teachers solve the rebuttals in class. The conclusions and implications based on the results are as follows: First, this study provided empirical data that the thinking process of validating core elements of argumentation and processes of argumentation is actively taking place in preservice teachers' lesson planning using the argument structure, and expanded the scope of application of argumentation in science education research. Second, the argument structure of learning contents should be used to help teachers to come up with strategies to induce students' curiosity and devotion to learn science contents. Third, preservice teachers should have the opportunity to think about the nature of science, including the variability and uncertainty of scientific knowledge when they discover rebuttals and develop solutions to them. Based on these conclusions, implications and suggestions for science education and further research were suggested.

In this study, we tried to find a way to improve the pedagogical decision-making practices related to the presentation order of 'large number' and 'small number' in problem situations of subtraction of the natural number. For this purpose, the elementary school teachers' perception about problem situations in real-life context of subtraction of natural numbers was investigated, and the collected data were analyzed qualitatively and quantitatively to identify teachers' pedagogical perceptions. As a result of this study, it was confirmed the need for consideration on how to set up a problem situations in real-life context of subtraction so that students can develop their ability to solve various types of problems. To this end, not only in a problem situation of subtraction where you have to think of 'large number' first and 'small number' later, but also about the introduction of problem situations in real-life context of subtraction in which you think about 'small number' first and 'large number' later, which often appears in real-life. You will need to recognize the need. And you should have a pedagogical view on this. The results of this study will be able to contribute to the preparation of pedagogical method that can expand the understanding of various problem situations where subtraction is applied from the lower grades of elementary school.

In this study, we examine the AI ethics perception of university students to explore the direction of AI ethics education. For this, 83 students wrote their thoughts about 5 discussion topics on online bulletin board. We analyzed it using language networks, one of the text mining techniques. As a result, 62.5% of students spoke the future of the AI society positively. Second, if there is a self-driving car accident, 39.2% of students thought it is the vehicle owner's responsibility at the current level of autonomous driving. Third, invasion of privacy, abuse of technology, and unbalanced information acquisition were cited as dysfunctions of the development of AI. It was mentioned that ethical education for both AI users and developers is required as a way to minimize malfunctions, and institutional preparations should be carried out in parallel. Fourth, only 19.2% of students showed a positive opinion about a society where face recognition technology is universal. Finally, there was a common opinion that when collecting data including personal information, only the part with the consent should be used. Regarding the use of AI without moral standards, they emphasized the ethical literacy of both users and developers. This study is meaningful in that it provides information necessary to design the contents of artificial intelligence ethics education in liberal arts education.

The purposes of this study are to examine what the participants experienced when developing Content Representation (CoRe) of "molecular motion" for the 7th grade in collaboration with experienced chemistry-trained teacher and non-chemistry-trained teacher and to investigate how the participants' PCK changed in their classes after developing CoRe. The participants were one experienced chemistry-trained teacher, two physics-trained teachers, and one researcher. The participants were selected by purposeful sampling. For this study, the discussions on developing CoRe was recorded and two physics-trained participants' classes were video-taped, and constructed/semiconstructed interviews were conducted. All data were transcribed for analysis. The participants experienced reflective thinking of their knowledge and previous classes, corrected their own misconception and clarified those conception, recognized the contents and the goals of "molecular motion" class, enhanced understanding of students' preconception during the development of CoRe. Especially, the two physics-trained teacher-participants confessed that they recognized clearly the contents and the goals of "molecular motion" class and identified their deficiency in 'particle viewpoint' in their previous classes. Their recognition was realized in the course of interaction with experienced chemistry-trained teacher. Among the components of PCK, knowledge of science curriculum was most influent on two physics-trained teacher-participants' classes, and they emphasized 'particle viewpoint' and 'molecular motion' in their classes. In addition, they introduced new teaching strategies that were discussed in the course of developing CoRe. The influence on the participants' PCK was different according to their reflective thinking on their own knowledge and previous classes and their affective characteristic. The implication of this study is that, the course of developing CoRe can promote reflective thinking that is essential for increasing teachers' professionalism and significantly influence on PCK. Especially, developing CoRe in collaboration with experienced chemistry-trained teacher and non-chemistry-trained teacher can identify deficiency in their classes and thereby, improve their classes. And, it takes time and effort to internalize the participant's recognition in their teaching practice.

This study was conducted to examine the effects of the elderly patient's simulation experience on attitudes toward elderly and elderly patients, and empathy of elderly patients among nursing students. Study results showed that elderly patient's simulation experience did not have significant effects on attitudes toward elderly or elderly patients, whereas it had significant effect on enhancing the empathy on elderly patients. The subjects of experimental group indicated that the factors decreasing the effect of intervention are single event of experience, raising aging anxiety, lack of the reality of simulation clothing, and risk of accident during simulation experience, etc. In order to maximize the positive effects of the elderly patient's simulation program, it is necessary to find a way to improve those limiting factors identified from this study, and to continue to work on positive effects of elderly simulation applied for their curriculum.
