Objective: The purpose of this study was to analyze the experiences of foreign students in childcare practicum, with a specific focus on identifying the difficulties they encountered and the values they derived from their practicum experiences. The aim was to gain insights that can contribute to improving practicum support for these students. Methods: A total of 6 foreign students were selected as participants for this study using snowball sampling. The data collection period spanned from May 2021 to March 2023, during which semi-structured interviews were conducted and qualitatively analyzed. Results: Foreign students faced challenges in securing practicum placements prior to the start of their program. Communication difficulties necessitated the use of interpreters to interact with children. Additionally, documenting information in a language other than their mother tongue posed a challenge. Consequently, there was a need for tailored training support to address the specific needs of foreign students in childcare practicum. Despite these challenges, the students reported rewarding and valuable experiences during their practicum. These experiences included discovering the teaching identity in Korea, learning about desirable practices in the field, recognizing and addressing personal shortcomings, and developing a sense of vocation for the advancement of infant education in their home countries. Conclusion/Implications: If we actively listen to and provide appropriate support for the specific needs of foreign students in their childcare practicum, they have the potential to become excellent childcare teachers who can foster a harmonious and inclusive environment within our multicultural society.

Knowledge distillation (KD) is a model lightening technology that transfers the knowledge of deep models to light models. Most KD methods have been developed for classification models, and there have been few KD studies in the field of super-resolution (SR). In this paper, various KD methods are applied to an SR model and their performance is compared. Specifically, we modified the loss function to apply each KD method to the SR model and conducted an experiment to learn a student model that was about 27 times lighter than the teacher model and to double the image resolution. Through the experiment, it was confirmed that some KD methods were not valid when applied to SR models, and that the performance was the highest when the relational KD and the traditional KD methods were combined.

The purpose of this study is to examine the pre-service teachers' concept of measurement uncertainty. The subject of this study were 27 pre-service middle-school teachers in Seoul. They carried out open-ended inquiry tasks and surveyed two kinds of open questionnaires, and interviewed several persons. We analysed their behavior and responses. Through the analysis, we summarize pre-service teachers' concept about measurement uncertainty with representation data, precision and accuracy, error analysis, propagation of uncertainty. The results show that the teachers' concept is different from scientists' concept. They make a mistake in using term of precision and accuracy and pay no attention to measure precisely. Also they only point out sources of error but don't consider how the error affects the results of experiment. The results of study will give! 1 some implications for the curriculum and teaching material developers in order that pre-service teacher and student gain scientific concept.

In this study, classroom instructions of teachers who participate in the science teachers' community were videotaped and analyzed to understand their teaching professionalism. Among the "Standards for teaching evaluation of science instruction" developed by Korea Education Curriculum and Assessment, 12 evaluation elements were selected and used for data analysis. First of all, the results indicate that most of the teachers show the highest teaching level in the interaction between student and teacher, and the lowest in the statement of teaching object as the teaching evaluation element. Second, from the viewpoint of the teaching level, all of the teachers at the superior level were veterans whose teaching careers have spanned longer than 15 years. It was found that they used various teaching materials in class and designed meaningful learning programs for their students. Compared with teachers at the superior level, beginning teachers used limited teaching materials due to their lack of experience. In addition, their instruction falls short of flexible management in teaching. The results show that they tend to teach in a somewhat rigid style that does not have sufficient positive interaction with students.

The purpose of this study was to investigate the relationships between the ability of students' raising creative problems and academic achievement, science inquiry skills and creative personality of high school students. In order to evaluate the originality of problems, the present study used three methods: evaluation by frequency, teacher, and student. The results in this study turned out to be as follows: First, there was not much difference in the three methods. But familiar problems had the possibility of receiving higher marks. Second, the ability of students' raising creative problems was significantly correlated with academic achievement and creative personality, but there was no correlation with science inquiry skills. The subjects were divided into 2 groups by students' originality score. In the higher score group, the ability of students' raising creative problems was significantly correlated with creative personality, but in the lower score group, it was significantly correlated with academic achievement. Third, as for science inquiry skills and creative personality between two groups, there was no significant difference, whereas as for academic achievement(physics I, chemistry I), there was significant difference.

The educational situation, which resulted from the announced self-isolation regime, intensified the forced decisions on the organization of the distance educational process. The study is topical because of the provision of distance learning based on the experience of Kyiv National University of Culture and Arts. The study was conducted in three stages. Systemic, socio-communicative, competence approaches, sociological methods (questionnaires and interviews) were chosen as methodological tools of the research. The results of a survey of teachers and entrants to higher education institutions on the topic "Using social networks and digital platforms for online classes under the conditions of quarantine restrictions" allowed to scientifically substantiate the need for deeper knowledge of such tools as Google Meet (79%), Zoom (13.78%) and Google Classroom (11.62%), which are preferred by entrants. Almost a third of entrants (34.26%) noted the lack of scientific and methodological support for learning the subjects. The study showed high efficiency of messengers in distance education. The study found that in the process of organizing communication in the student-teacher system, it is necessary to take into account the priority of Telegram on the basis of which it is necessary to implement a chatbot for convenient and effective exchange of information about the educational process. Further research should focus on the effectiveness of the use of Telegram. The effectiveness of using chatbots should also be considered. Chatbots can be used to automate routine components of the learning process.

This study analyzed students' mathematical noticing in high school sequence classes based on students' two perceptions of sequence. Specifically, mathematical noticing was analyzed in four aspects: center of focus, focusing interaction, task features, and nature of mathematics activities, and the following results were obtained. First of all, the change pattern of central of focus could not be uniquely described by any one component among 'focusing interaction', 'task features', and 'the nature of mathematical activities'. Next, the interactions between the components of mathematical noticing were identified, and the teacher's individual feedback during small group activities influenced the formation of the center of focus. Finally, students showed two different modes of reasoning even within the same classroom, that is, focusing interaction, task features, and nature of mathematics activities that resulted in the same focus. It is hoped that this study will serve as a catalyst for more active research on students' understanding of sequence.

The purpose of this study is to analyze the characteristics of beginning teachers in elementary school as they experience the lifecycle of teachers, to analyze and comprehend the difficulties of these teachers based on their characteristics, and to propose a resolution strategy. The study is intended to assist beginning teachers in adapting well to their work and profession as teachers in order to contribute to the growth in quality of education; it is also intended to prepare beginning teachers to utilize their time in elementary school as a period of self-improvement to become proficient teachers. The difficulties in human relations that beginning teachers experience in school can be divided into three major categories: relations with administrators and fellow teachers, relations with parents of students, and relations with students. The standardized and uniform culture of a school and the administrators and fellow workers imposing such a culture are the reason for the difficulties that beginning teachers face, and the question of what kind of fellow teachers the beginning teachers will encounter in their first school exerts a serious influence on the growth of these teachers, who have just begun their career in education. Furthermore, the lack of skills to discipline students eventually leads beginning teachers to face difficulties in controlling students in the classroom, and the process of encountering and resolving various classroom problems contributes to the growth of teachers' proficiency. Moreover, the attitude of students' parents who behave toward them as novice teachers serves as the reason for beginning teachers to lose their confidence or face difficulties in their careers, and exerts an influence on student counseling and guidance. The resolution strategy that beginning teachers apply as they encounter such problems with the entities in the educational field is as follows: imitation, listening, and accepting the thoughts and to renounce. To resolve the difficulties that beginning teachers experience, it is necessary to allocate space and time to discuss their difficulties and possible plans for resolution during the beginning teachers' training period and initiate a mentoring system in schools. Lastly, it is necessary that the offices of education continuously conduct qualitative research on beginning teachers and publish casebooks on such studies.
