The present study examined the relationships between work related flow (i.e., absorption, work enjoyment, and intrinsic work motivation) and role conflict causes (i.e., teacher's belief, teaching and interaction with young children, comradeship, relationships with parents, workload, supervision, and social awareness of the job). A canonical correlation analysis was performed on the data from a sample of 154 childcare teachers. The results are as follows (1) there was a reciprocal-causal relationship between teachers' role conflict causes and their work-related flow; (2) canonical function 1 showed that absorption and work enjoyment are strongly associated to a teacher's belief and supervision of conflict causes; and (3) canonical function 2 showed that intrinsic motivation has a relatively strong relationship with workload and supervision of conflict causes. It can be concluded that it is important for childcare teachers to have sufficient job resources to promote their flow at work. Further research is needed for investigation of teacher's flow at various conditions of work.

This study examined the relationship among supervision behaviors, self-efficacy, and job stress of childcare teachers for infants. This study also investigated whether the childcare teachers' supervision behaviors affected self-efficacy and job stress and whether their self-efficacy acted as a mediating effects on job stress and supervisory behaviors. The participants were 292 childcare teachers for infants in Seoul and Gyeonggi-do. The instruments utilized were the parent supervision attributes scale, Korean occupational stress scale, and teacher self-efficacy scale. The data analyzed by means of Pearson's correlation coefficients and hierarchical regression analysis. A hierarchical multiple regression analysis, Which Baron & Kenny first proposed, was conducted. The significance of the mediation effect was verified by the Sobel test. The results were as follows: First, the childcare teachers' supervision behaviors had a positive correlation with the teachers' self-efficacy, while the teachers' supervision behaviors and self-efficacy had a negative correlation with job stress. Second, job stress appeared to have a negative on supervision behaviors. Self-efficacy appeared to have a positive effect on supervision behaviors. Third, the mediating effect of self-efficacy was verified in the relationship between supervision behaviors and job stress. The more self-efficacy the childcare teachers had, the more supervision behaviors they performed. The greater their self-efficacy, the more the childcare teachers were able to control job stress. Therefore, by enhancing the self-efficacy of childcare teachers, their level of supervision behaviors should increase and their level of job stress should decrease.

Purpose: This study was conducted to evaluate the validity and reliability of the Korean version of the clinical learning environment, supervision and nurse teacher evaluation scale (CLES+T) that measures the clinical learning environment and the conditions associated with supervision and nurse teachers. Methods: The English CLES+T was translated into Korean with forward and back translation. Survey data were collected from 434 nursing students who had more than four days of clinical practice in Korean hospitals. Internal consistency reliability and construct validity using confirmatory and exploratory factor analysis were conducted. SPSS 20.0 and AMOS 22.0 programs were used for data analysis. Results: The exploratory factor analysis revealed seven factors for the thirty three-item scale. Confirmatory factor analysis supported good convergent and discriminant validities. The Cronbach's alpha for the overall scale was .94 and for the seven subscales ranged from .78 to .94. Conclusion: The findings suggest that the 33-items Korean CLES+T is an appropriate instrument to measure Korean nursing students'clinical learning environment with good validity and reliability.

The purpose of this study was to investigate what middle school Home Economics(HE) teachers perceive, practice and need for self-supervision at school related to HE. Questionnaires were sent by E-mail and 150 were collected. Descriptive statistics including frequency, percentage, average, standard deviation, t-test and ANOVA analysis were reported using SPSS/win 10.1. The results of this research were as follows: First, middle school HE teachers perceived that self-supervision at school was essential since it promoted self reflection of teachers themselves and improved professional skills. Furthermore, peer-coaching was highly preferred. Second, negative responses to the supervision of principal, vice-principal, and peer teachers overwhelmed positive answers. Information exchange among peer teachers was frequent, yet, approximately 22.6% of middle school HE teachers were still avoiding sharing information process for several reasons. About half of the teachers answered that all teachers needed to participate in this process. Third, they pointed out that self-supervision at school was not implemented well because of the lack of time due to the heavy work load, negative and passive attitude for the improvement of teaching-learning activities, administration-centered supervision that did not reflect teachers' opinion, and shortage of economical, and environmental support.. HE teachers perceived that peer teachers who were doing good practices were most helpful for the supervision. Also, they preferred self-evaluation at the end of the self-supervision at school. Forth, to improve self-supervision at school, there were very high demands for reduction of administrative work, additional time, fundamental philosophy toward HE education. Fifth, the purpose and detailed plans of self-supervision were recognized as the results that were democratically derived by the HE teachers. Sixth, class inspection and informal inspection were operated once in a year, and self-training was rarely operated. Peer coaching and self-coaching were operated occasionally. Self-coaching and peer coaching were reported as the most helpful types of supervision. In addition, HE teachers answered that supervision was helpful to teaching method followed by contents, evaluation, and philosophy of education.

This study explored the meaning of beginning teachers' first-year experience in an eco child educare center. Participants were 4 teachers at survival stages of teacher development; they had had the same preservice experience. Data were collected by semi-structured in-depth interviews, participant observation, researcher's field notes, and document collection. Five themes emerged as first year teachers' struggles and strategies for survival : (1) caring for children's daily lives vs. responsibility for formal education, (2) planned lessons vs. ease in teaching, (3) agreement or disagreement on philosophy of running the education program, (4) paradox of teacher empowerment, (5) overcoming struggle through voluntary peer supervision. These results indicated that beginning teacher' experiences at the survival stage varied by contextual and personal factors.

The school library plays very important and central role for the fullfillment of educational objective in the process of implementing the school curriculum. And the media specialist known as teacher-librarian is. primarily responsible for the successful operation and effective management of the media center. It is true that effectiveness of the school library depends greatly on the cooperative coordination among teacher-librarian, teacher and principal in addition to the strong support and effective supervision of school district authority, specifically, supervisor of school library program. The successful program therefore is influenced by their perception of the teacher-librarian's role. The purpose of this study was to investigate the teacher-librarian's. educational role perceived by teacher-librarian, teacher, principal and school district supervisor. A standard task model describing both the management and educational functions and expectations of teacher-librarian was proposed after studying the relevant current standards of four countries. Serveral hypotheses were made regarding role perception and a survey instrument was designed based on this proposed task model and the results of the literature review to validate the hypotheses. The questionnaires were mailed out and the returned questionaires were analyzed by SPSS computer routine. The major findings are summarized as follows: 1) There was difference of the role perception among teacher-librarian, teacher, principal and district supervisor at the significance level of p<0.001 for both management and educational functions of teacher­librarian. The mean score of the teacher-librarian was highest among four groups and the score for the educational function tasks were lower than that of management function tasks. 2) The positive correlation exists at the significance level of p<0.001 between the role perception and the attitude toward changing social trends such as acceptance of new technology, need for better communication and information. 3) The positive correlation exists at the significance level of p<0.001 between the role perception and the view on the curriculum and teaching method.

The purpose of this study is to clarify conceptually the difference of instructional coaching, instructional supervision, and instructional consulting by analyzing their own characteristics. The practices for instructional improvement are common in that fundamental objectives are improvement of instruction and development of teacher's professionalism in instruction. However, each area changed according to the social flow and the demands of the educational field and created a unique activity system. So, in order to get rid of this mixed use of these terms, it is meaningful to distinguish the concepts, attributes, and areas of each activity. The specific study questions were 1) what is the origin of coaching, supervision, and consulting? 2) how are instructional coaching, instructional supervision, and instructional consulting defined in existing research in korea? 3) how can we conceptually distinguish instructional coaching, instructional supervision, and instructional consulting? Based on reviewing various existing studies, First, this study investigated the conceptual origins and lexicons of coaching, supervision, and consulting, respectively, in addition reviewd the prior studies conducted in Korea with regard to instructional coaching, instructional supervision, and instructional consulting, and summarized how each concept is defined according to the researcher. Second, this study compared each two concept with another one. Finally, the existing definitions of instructional coaching, instructional supervision, and instructional consulting were analyzed to find out the inherent and common attributes of each concept. In conclusion, this study suggest that the concept of instructional consulting needs to be redefined to better reflect the characteristics of activities, and that studies that rethink the relationship between instructional coaching and instructional supervision are needed.

This paper proposes a novel approach for training an unsupervised depth estimation algorithm. The objective of unsupervised depth estimation is to estimate pixel-wise distances from camera without external supervision. While most previous works focus on model architectures, loss functions, and masking methods for considering dynamic objects, this paper focuses on the training framework to effectively use depth cue. The main loss function of unsupervised depth estimation algorithms is known as the photometric error. In this paper, we claim that direct depth cue is more effective than the photometric error. To obtain the direct depth cue, we adopt the technique of knowledge distillation which is a teacher-student learning framework. We train a teacher network based on a previous unsupervised method, and its depth predictions are utilized as pseudo labels. The pseudo labels are employed to train a student network. In experiments, our proposed algorithm shows a comparable performance with the state-of-the-art algorithm, and we demonstrate that our teacher-student framework is effective in the problem of unsupervised depth estimation.

The method used in this descriptive study is the survey. The purpose of the study is to investigate performances of middle school home economics(HE) teachers regarding the HE subject. Respondents in this study were 177 HE teachers. Questionnaires from HE teachers were collected through e-mails. With the operation of the SPSS/Win (ver10.1) program, the analyses such as mean, standard deviation, frequencies, percents, t-test and ANOVA are done to see the relations between the related variables. The results of this study were as follows. First, the middle school HE teachers performed well above the standards in terms of planning, execution, and evaluation about self supervision related to HE. Second, the HE teachers collected materials for instruction by using literary (books) survey, Internet and mass media. They mainly focused on improving ways of "teaching and learning" and deepening the studies related to contents of textbooks. Third, the HE teachers used various ways to improve self supervision in the following order: mass media, literary (books) survey, participation in societies for researches, meetings, various training and field trip More than half of the middle school HE teachers proceeded to graduate schools, joined meetings for researches and had experiences of taking classes in private institutes. They also made a field trip once or twice a year and depended much on TV programs and education broadcasting programs as ways of improving their performances related to self supervision. While they were actively sharing information with their peer group, they made little effort at analyzing and evaluating their classes and utilizing expert group for their classes. The main problems as to self supervision were that only the half of the HE teachers responded that they were performing self supervision related to their classes well above the standards and the area where they heavily focused on has been "teaching and learning" and "the studies related to contents of textbooks". Therefore, to motivate incentives of the HE teachers for self supervision, meetings for researches should be activated and various training programs should be developed. In addition, government should give administrative and institutional support through a publication of books introducing detailed ways of self supervision and an establishment of centers and institutions for supporting self supervision.

This study examined the effects of day-care center organizational characteristics on teacher efficacy. The participants of this study were 319 day-care center teachers who work in the Seoul-Gyeonggi area. The results of this study are as follows: First, day-care center teacher efficacy shows the difference depending on the teachers' career. Second, teachers' efficacy was influenced by day-care center organizational characteristics. In particular, it appeared that 'challenge' and 'distinction of role' affect teacher efficacy when the career of the teacher is less than 5 years. And it appeared that 'challenge', 'distinction of role' and 'retraining' affect teacher efficacy when the career of the teacher is more than 5 years. We discussed organizational characteristics for improving teacher efficacy and suggested the implication for retraining teachers and supervision to promote teacher efficacy based on the results.
