This study explored the effects of pre-service elementary teachers' inquiries into science class dilemmas. By closely examining the characteristics of the pre-service teachers' inquiry processes and changes in their educational decisions, the effectiveness of using dilemmas as part of teacher education was determined. Twenty fourth-year university pre-service teachers participated and conducted inquiries into science class dilemmas over seven weeks. Based on pre- and post-questionnaires, KWHL tables, inquiry reports, discussions, and group class presentations, the major factors that influence the pre-service teacher's decision-making changes were extracted. The pre-service teachers found the science inquiry process meaningful when exploring the science topics covered in the dilemmas, and claimed that elementary school students would be able to engage in meaningful science explorations if they learned science through inquiry. Furthermore, the pre-service teachers explored the thinking processes and background knowledge of the students in different ways. Documents such as teacher's guides and the curriculum were examined and the students' thought processes were identified through interviews with the teachers and students, which were found to reflect their educational decision-making. Moreover, it was recognized by the pre-service teachers that depending on the situation, alternative teaching methods were possible. The focus on the unstructured dilemma problems provided the pre-service teachers with problem-solving situations that triggered scientific inquiry and exploration of student thinking and revealed the complexity of science teaching and learning. Based on these results, the teacher education implications for using dilemma cases are discussed.

This article is devoted to the study of the process of formation of the digital generation in a distance learning environment. With the introduction of quarantine due to the spread of COVID-19, opponents of digital technologies were forced to turn to relevant resources, while supporters identified new opportunities for the development of didactics and education in general. The irreversibility of the former educational reality became apparent and only the scale of the vision of potential change by interested and disinterested groups differed. Using a comprehensive approach, the authors consider the issues related to the direct and indirect impact of distance learning on children and young people born after the beginning of the XXI century. The article reveals the prerequisites and implications of distance education for the interaction of participants in the educational process. IC technologies during the educational process in the primary grades, in addition to identifying the student's learning deficit, should provide the transmission of non-verbal signals, which are important for children of this age. At the same time in the secondary school IR-technologies are designed to replace frontal learning during the assimilation of knowledge and at the same time not to worsen the quality of the educational process. Formation of students in the HEI takes place in the political science format, constant discussion of problem situations, so the task of introducing IC technology in this process is the accurate transfer of the content of the discussions. Individualization and autonomization of the educational process, its dependence on the results of the choice of educational content, and the use of pedagogical management tools change the philosophy of education for children and youth. The authors conclude that the formation of a digital generation, characterized by an increased level of digital literacy of children and youth, the possession of a certain level of digital capacity requires the use of strategies aimed at optimizing the learning process in a digital educational environment.

This study is based on Freudenthal's mathmatising process and the didactical phenomenology of linear function concept, I have described and examined the process in which students represent the constant rate of change into tables, graphs and equations and, in this way, how they construct mental objects and essence of the linear function concept. The students used the proportionality as composite units, when they represented the phenomenon with constant rate of change into tables. When representing in graphs, all but one student represented it into a line. There were differences among the students in the level they were using the given conditions, co-variation perspective, and corresponding rules when formulating equations. The students compared the relationship between two variables in a multiplicative way, and under the guidance of teachers they reached to the understanding that its relationship becomes a constant. Moreover, they could construct mental objects of a constant rate of change, understanding the situation where the relationship between time difference and distance difference becomes one value, namely speed. The students had difficulties in connecting the rate of change with the inclination of a line. The students constructed the essence (concept) of linear functions, after building and organizing the image that the rate of change is constant, the graph is linear, and the equation is formulated as y=ax+b (a: inclination, b: intercept).

This study examined longitudinal mediated effects of informal labeling on the relationship between adolescent abuse and academic achievement using autoregressive cross-lagged modeling. Data were obtained from the second, third, and fourth waves of the middle school student cohort (N=3,168) of the Korean Youth Panel Survey. The major longitudinal findings of this study are as follows: First, adolescent abuse was found to have a positive association with future informal labeling. Second, informal labeling was found to have a negative association with future academic achievement. Finally, the longitudinal relationship between adolescent abuse and academic achievement was partially mediated by informal labeling. Based on these results, this study suggests directions for adolescent abuse prevention. The need for education and prevention of informal labeling was discussed, as well as the direction of intervention programs for adolescents with experience of informal labeling. Furthermore, this study may provide empirical evidence for labeling theory and contribute to increasing awareness on the longitudinal influence of adolescent abuse and informal labeling.

This study examined the reasoning of gifted elementary science students in a socioscientific issues (SSI) classroom discussion on COVID-19-related trash disposal challenges. This study aimed to understand the characteristics of evidence use and decision-making difficulties in each type of SSI-related reasoning. To this end, the transcripts of 17 gifted students of elementary science discussing SSIs in a classroom were analyzed within the framework of informal reasoning. The analysis framework was categorized into three types according to the primary influence involved in reasoning: rational, emotional, and intuitive. The analysis showed that students exhibited four categories of evidence use in SSI reasoning. First, in the rational reasoning category, students deemed and recorded scientific knowledge, numbers, and statistics as objective evidence. However, students who experienced difficulty in investigating such scientific data were less likely to have factored them in subsequent decisions. Second, in the emotional reasoning category, students' solutions varied considerably depending on the perspective they empathized with and reasoned from. Differences in their views led to conflicting perspectives on SSIs and consequent disagreement. Third, in the intuitive reasoning category, students disagreed with the opinions of their peers but did not explain their positions precisely. Intuitive reasoning also created challenges as students avoided problem-solving in the discussion and did not critically examine their opinions. Fourth, a mixed category of reasoning emerged: intuition combined with rationality or emotion. When combined with emotion, intuitive reasoning was characterized by deep empathy arising from personal experience, and when combined with rationality, the result was only an impulsive reaction. These findings indicate that research on student understanding and faculty knowledge of SSIs discussed in classrooms should consider the difficulties in informal reasoning and decision-making.

The purpose of this study was to examine the phenomena that occurred when the students were practicing flip-learning lessons and to present the good points and the unsatisfactory points to improve the students' learning pleasure. Therefore, it is aimed to provide the basic data and the advantages and disadvantages which are needed to apply the flip learning method which is newly emerging recently to the university instruction. The method of this study was a questionnaire survey to understand the perception of flip learning. Based on the results of this study, the following conclusions are presented. First, the experience of flip learning instruction was first encountered by 50% of college students. Second, the students showed a very low tendency in practicing the flip learning instruction(video watching) the instructor intended. Third, college students have a habit of learning that they are not ready for pre-study of the subject. Fourth, the perception of flip learning lesson through the provision of video was highly positive. Fifthly, flip learning lessons have the advantage of being able to learn regardless of the time and place that they have, but they are not actively involved if they are not actually reflected in the test or grades. In conclusion, it was found that college students became accustomed to the incentive-style lessons due to the application of various learning techniques from elementary school age, making it difficult to participate in voluntary learning.

This study is a descriptive research to investigate the effects of nursing college students in graduation year, self-management competency and grit on employment preparation behavior. The data were analyzed using SPSS 26.0 program, frequency analysis, t-test, ANOVA, Pearson's correlation, and multiple regression. Self-management competency(r=.41, p<.001) and persistence of effort(r=.44, p<.001) of the grit sub-factor showed a positive correlation with employment preparation behavior. Interest consistency(r=-34, p<.001) of the grit sub-factor and employment preparation behavior showed a negative correlation. Self-management competency(β=.27, p<.01) and persistence of effort of the grit sub-factor(β=.22, p<.01) had a positive effect on employment preparation behavior. Interest consistency of grit sub-factor(β=-.32, p<.001) showed a negative effect on employment preparation behavior. In order to promote the employmentt preparation behavior of nursing students, it is necessary to improve self-management competency and persistence in effort. It also suggests that a strategy to suggest various nursing-related employment fields is needed to reduce interest consistency.

In order for SW education to be established in the era of non-face-to-face caused by COVID-19, research on the efficiency of SW education according to face-to-face and non-face classes is needed. Therefore, this study classified the operation status of the curriculum of 30 SW gifted classes nationwide in 2020 according to the class method(face-to-face, non-face, and blended). Subsequently, the results of class time and production per person were compared and analyzed through quantitative analysis. According to the study, the type of classes that performed the most classes compared to the planned number of hours was non-face-to-face(90.9%), followed by face-to-face(84.2%) and the least was blended(80.5%). The average number of products per student was the highest in the face-to-face class(0.504), while the blended class(0.421) and non-face-to-face class(0.42). Based on the results of this study, the non-face-to-face approach is advantageous in securing the number of hours, but various measures should be prepared to solve this problem because teachers and students find it difficult to guide the output.

Customer engagement refers to the physical and emotional connection between customers and brands. If the customer's degree of engagement is high, they purchase more, promote more, and show more loyalty. This study suggests the following implications, starting from the assumption that engagement with various service activities in universities can increase loyalty to departments and Universities. In university services, customer engagement plays a important role in strengthening college loyalty after college students are satisfied with university. Although it has an effect on university satisfaction, it can play a big role in increasing the loyalty of marketing goals at a higher level after satisfaction. Among the central factors of university service engagement, it was found that students could increase their department and university loyalty through capacity building and job-related activities for future employment, and among the surrounding factors, friendship activities were a very important factor in department or school loyalty. It can be said that it is of paramount importance to establish a system that can strengthen loyalty through various programs that can build friendships with students. Further research did not verify the moderating effect of service engagement among student groups, but the high-credit group was found to have a very high degree of engagement not only in the central cues but also in the peripheral cues, which is thought to reverse the common sense that high-credit students will be relatively less immersed in the peripheral elements.

Purpose: This study was conducted to investigate the eating behavior (EB) and nutritional status of university students in Gwangju, and to compare their nutrition quotients (NQs) and problems according to their EB types. Methods: The subjects were 219 (127 female and 92 male) undergraduate students from Gwangju. The Student's t-test was used to compare the EB levels according to gender, and Pearson's χ² test was used to compare the distribution of EB types by gender. A gender-adjusted analysis of covariance (ANCOVA) was conducted to examine the difference in NQs by EB types. Results: First, there were significant differences in the EB scores and the distribution of EB types according to gender. Female students showed higher levels of emotional (Emo) and external (Ext) EBs than the male students, and Emo, Ext, and combined (Com) EB types were more evident among female rather than male students. Second, there was a difference in NQs according to the EB types. The Emo EB type subjects had a lower NQ than those of the restrained (Res) EB type and showed significant differences in diversity and dietary behavior. Specifically, the Emo EB type subjects displayed significantly lower efforts to maintain a healthy diet and subjective health status than the Com EB type and their levels of checking nutrition labels, hand washing, and water intake were significantly lower than that of the Res EB type. The Ext EB type showed significantly lower moderation of Ramyeon and sweetened drink intake than the Res and Com EB types. Conclusion: The level of EBs and the distribution of EB types varied according to gender, and the NQs were different according to EB types. The results of this study are expected to contribute to the establishment of customized strategies for improvement by identifying major nutritional problems by gender and the EB types of university students.
