The purpose of this study was to analyze the examples presented in the "Separation of Mixtures" section of the 2015 revised science authorized textbook introduced in elementary schools in 2022 and to see how the teachers and students understand the concept. To do that, 96 keywords were extracted through three cleansing processes to separate the elements of the mixture presented in the textbook. In order to analyze the teachers' perceptions, 32 teachers at elementary schools in Gyeonggi-do received responses to a survey, and a survey of 92 fourth graders who learned the separation of the mixture with an authorized textbook in 2022 was used for the analysis. As a result, as for the solids, 54 out of 96 separations (56.3%) showed the highest ratio, and the largest number of cases were presented according to the characteristics of the development stage of students. It was followed by living things, liquids, other objects and substances, and gasses. By analyzing the mixture, the structure and the interrelationships between the 96 extracted keywords were systematized through the network analysis, and the connection between the keywords, which were a part of the mixture was analyzed. The teachers partially responded to the separation of the complex mixture presented in the textbook, but most of the students did not recognize it. Because the analysis of the teachers' and students' perceptions of the seven separate categories presented in the survey was not based on a clear conceptual perception of the separation of the mixture, but rather they tended to respond differently for each characteristic of each individual category, it was decided that it was necessary to present clearer examples of the separation of the mixture, so that the students could better understand the concept of separation of mixtures that could be somewhat abstract.

The purpose of this study is to suggest how to activate the school library by examining how the users' perceive teacher librarians. For this purpose, questionnaires and in-depth interviews were conducted for students in 10 middle and high schools in Seoul and Gyeonggi. Analyses lead to these findings: the image types of teacher librarians were classified as professional image, active image, and simple-work image. Multiple regression analysis was used to examine the effect of teacher librarians images on school library user satisfaction. In order to enhance the teacher librarians images and school library user satisfaction, it is necessary to strive to cultivate the active attitude and professionalism of teacher librarians. Also, as the frequency of use is lower, the teacher librarians' images are viewed as simple work. Therefore, it is required to consider various reading events and reading education to raise the frequency of use. This study shows that the teacher librarians' images have a positive effect on school library users' satisfaction and suggests improvement plan for school library activation.

This study investigated high school student and chemistry teacher perceptions on the effect of water vapor in the air on evaporation and boiling of water by a questionnaire. In science textbooks evaporation and the boiling of water are related to the vaporization concept, boiling is related to vapor pressure and air pressure, and vapor pressure is related to the vapor concept in the air. High school student and chemistry teacher perceptions on these linkages were compared. Science textbooks were also analyzed for reasons behind these diverse perceptions. Results revealed that a majority of students conceptualized that vapor in the air was related to evaporation and boiling, but were unable to distinguish the evaporation phenomena at the macroscopic level and the evaporation of water molecules at the microscopic level. They also thought that vapor in the air affected vapor pressure and boiling. Although the percentage of teacher scientific conception was higher, a great number of teachers had diverse perceptions on evaporation and boiling just as students had. Common explanations of evaporation and boiling phenomena in science textbooks were at the macroscopic level. Moreover, there were few connections of concepts even if the explanations were at the microscopic level.

There is a paucity of research on socialization of novice teachers that has been found to have influence on their career through studies in different subject fields in various regions. This study addresses how novice English teachers perceive their socialization at the first years. It aims to draw implications for novice teacher support for training and professional development. Data were obtained from a questionnaire survey. From the review of the relevant literature, six themes were identified as significant factors in novice teachers' socialization process: relationship with pupils, teaching, rapport with colleagues, support from headteachers, relationship with parents, and expectations from the society. There were 44 questions under six key factors. 99 secondary English novice teachers participated in the survey. The analysis of the gathered responses to each question reveals information on their socialization process to become a secondary English teacher including adaptation challenges for professional development, which have been neglected but are gaining more attention from different stakeholders. This is being increasingly supported in the time of the coronavirus (COIVD-19) pandemic crisis, disruption and recovery. The study is concluded with some implications for research on novice teacher induction, and teacher education policy and practice.

The purpose of the study is to examine the relationships of parents' satisfaction towards their children's school education and the demographic variables associated with decision-making on post high school academic completion of parents of the students with disabilities. The Korean Education Longitudinal Study data, which contained the responses of 162 parents of high school students with mild disabilities who enrolled in regular high schools, was used for the study. For data analysis, descriptive statistics, ordinal logistic regression analysis, and chi-square test were used. As a result, provision of college entrance related information/consultation, improvement of academic performance level, collaboration/ communication between the teachers and parents, and overall school education were significantly related to parents' decision-making on their children's post high school academic completion. Also, mothers' educational level showed significant difference in parents' decision-making on their children's post high school academic completion.

This study aimed to identify the difficulties that new science teachers in secondary schools experience. Subjects for this study were 190 science teachers attending qualifying training for 1st degree of teaching certificate. Using an open questionnaire, the difficulties these teachers encounter were collected, categorized, and compared between their first year and their succeeding years of teaching in terms of their school level, gender, majors and regions. Results showed that first year science teachers have had difficulties in areas including subject teaching, guidance, administrative affairs, human relationship and self-understanding. On their succeeding years, difficulties about subject teaching were reduced to half while other difficulties remained. New teachers in middle schools have experienced the most number of difficulties about guidance, while new teachers in general high schools have experienced the most number of difficulties about subject teaching. Based on these findings, some recommendations were proposed for new science teachers in secondary schools, school administrators, and training institutions.

In this study, prospective teachers were involved in arranging the teaching sequence of multiplication and division of fractions and decimal numbers based on their experience and knowledge of school mathematics. As a result, these activities provided an opportunity to demonstrate the prospective teachers' perception. Prospective teachers were able to learn the knowledge they needed by identifying the differences between their perceptions and curriculum. In other words, prospective teachers were able to understand the mathematical relationships inherent in the teaching sequence of multiplication and division of fractions and decimal numbers and the importance and difficulty of identifying students' prior knowledge and the effects of productive failures as teaching methods.

This study analyzed the process of establishing a social structure in a third-grade mathematics classroom for one semester and explored learning processes based on various social interactions and relationships between the teacher and students. In the early phase of the semester, main foci were placed on establishing an overall social norms and basic social structure for effective mathematical learning. In the middle phase of the semester, an emphasis among students' interactions was given to exploration of mathematical concepts. Students tended to ask whatever they did not know exactly and clearly understood what to explain. In the late phase of the semester, students' individual disposition was further considered. Disciplinary personality traits including intellectual courage, honesty, consideration, and cooperation were emphasized along with mathematical exploration. Based on these research results, this study was intended to provide implications for implementing more meaningful mathematics lessons by fully considering not only mathematical connections but also social connections.

This study examined the elementary school teachers' present utilization of science museums in teaching-learning and their perceptions of the educational programs in science museums. The results indicate that teachers have not utilized science museums as intimately as possible with formal instruction, therefore, the students' experiences of science museums are usually limited. The main reasons for lower than optimum usage of science museums in their teaching and learning is not because of its insignificant educational effects, but because of the lack of external and administrative support mechanisms. The elementary school teachers prefer to commit to programs in science museums such as science camps or experiment activities, and those exhibitions which have some kind of clear and discernable relation to the school curriculum. The results also indicate that most teachers want to participate in the various activities of science museums, such as developing and managing the programs or pre- and post activities for museum field trips, participating in the teachers' community in science museums, and so on.
