The purpose of this study is to subdivide responsive teaching types proposed in the previous study in order to observe the change in the responsive teaching types in teacher educational programs, and to identify factors that impede changes in responsive teaching types. To this end, an educational program including introduction of responsive teaching, case analysis of responsive teaching, individual assignments and group discussions on facilitator type educational scenarios is provided for chemistry teachers who participated in a chemistry education course established in a graduate school of education. Based on previous research, when the teacher's teaching method was analyzed as evaluator, transfer, guide and facilitatore, a type that could not be classified was observed. In this study, responsive teaching types were added by adding two types: explorer and interpreter. In addition, through individual assignments and group discussion data, we could observe the factors that hinder teachers' responsive teaching changes. The obstacles that impede the change to responsive teaching were classified into teacher factors, student factors, and environmental factors. Among the obstacles, teacher factors include a belief in teacher-led instruction, a belief in the role of a teacher as a transfer of knowledge, a belief that the curriculum should be followed, a lack of understanding of the teacher about students, and a lack of the teacher's ability to lead student-led expansion. The student factor was distrust of the student's competence. Also, as an environmental factor, there was an educational environment such as multi-students class. Effective teacher education on responsive teaching can be achieved only when the perception related to these obstacles can be removed.

The purposes of this study are to investigate the change in the teacher efficacy beliefs of elementary pre-service teachers in mathematics during the student teaching, and to suggest the direction of the student teaching program for improving the pre-service teachers' efficacy beliefs in mathematics. For this, 93 elementary pre-service teachers participated. After the 4 weeks of practice, any changes in their teacher efficacy beliefs in mathematics were analyzed and the positive and negative causes of the differences were discussed. Consequently, their teacher efficacy beliefs in mathematics meaningfully decreased. The analysis of the cause of the decrease indicated that the teacher efficacy beliefs in teaching mathematics, rather than in the management of their mathematics class, meaningfully decreased. The meetings with the subjects also revealed that they had more negative experience with class teaching and were not able to gain much positive experience with it after all.

An effective teacher community helps the participating teachers improve their instructional quality. This study reports a teacher community consisting of 15 elementary school teachers and one teacher educator. This paper analyzed 15 mathematics lessons in which the teachers implemented the five practices for orchestrating productive mathematics discussions by Smith and Stein (2018) based on the grade-specific discussions as well as the whole community's discussions. The results of this study showed that the overall levels of each practice either increased gradually or maintained at the highest Level 4, as mathematics lessons had been implemented. Specifically, the following practices were quite successful: setting goals for a lesson, selecting an appropriate task, anticipating student responses, and selecting student solutions. However, both sequencing and connecting student solutions were implemented at various levels. Monitoring student work tended to remain at Level 2 which included incorrect implementation of the practice. This paper closes with implications related to the skillful implementation of the five practices through a teacher community.

The goal of the study is to find the necessary measures to facilitate a desirable Technology and Home Economics curriculum by reflecting the perception and needs of the teachers, principals, educational specialists from the perspective of the curriculum content, professionalism of the teacher, realistic operations of the school, and the administration of the school system. The research was executed through mail surveys to nationwide junior high school technology teachers, home education leachers, principals and to educational specialists. The results obtained from the research are as follows. 1) The integration of Technology and Home Economics was perceived to lessen the burden of students. However the background knowledge and characteristics of the two curriculums are different, and in addition there is a negative perception due to the fact that it is hard to facilitate a class with just one teacher, 2) The issues that were most serious to teachers, principals and education specialists were professionalism of the teacher, qualification of the teachers, and teaching method. 3) In regards to qualifications of the teacher, the teachers requested that teachers should have single qualification in'Technology(or Home Economics)'. The principals were of the similar opinion but the educational professionals wanted dual qualification for both'Technology'and'Home Economics'. As for teaching methodology all 3 groups responded that from the teacher and student perspective the teaching should be divided whereas from the school's perspective the responsibility should be put on a single teacher. 4) Teachers responded that from the perspective of the teacher, parent or student Technology and Home Economics should be separated into taro subjects. On the other hand the principals and educational specialists agreed that from their own perspective Technology and Home Economics should remain an integrated subject and the teaching should be done by one teacher but replied that from the student or parent perspective division of responsibility in teaching would be appropriate.

The myth reflects the human way of thinking about the world. Therefore, an important part of myth is human creation and role. This study examines the process of human creation in myth and discusses implications for education. The subjects that can be considered from the viewpoint of education are as follows. The status and role of teachers and students, the relationship between teachers and students, how to create or create humans, and the purpose and results of human creation. First, it is the position and role of the teacher. In myth, being like a teacher is a divine being that transcends human ability. In Dangun mythology, Hwanwoong or Shinwoong descended from heaven, and in the Genesis it is the Creator God. In Dangun mythology, the role of the teacher guides the way of becoming a human and provides necessary tasks. In Genesis, the image of the teacher is the Creator God. God plays the role of a teacher who prepares various environments in which learners can work. Second, the status and role of students in myths. In Dangun mythology, students are symbolized by bear and tiger. They go to the teacher with the desire to become human beings. In Dangun mythology, the student is not a passive existence but an autonomous and active image. In Genesis, the appearance of a student is a passive being created by a teacher. Third, the creation of human beings in myth can be seen in terms of educational process and method. In Dangun Myth, the beginning of education is the wish or expectation of learners. Learners eat mugwort and garlic and participate in human learning. In Genesis 1, however, there is no need for a special method, since human beings are created according to the Creator's command. Fourth, the purpose of education can be discussed through the purpose of human creation. In Dangun mythology, the purpose of education is not to live according to instinct but to become human with culture and personality. In Genesis 1, the purpose of human creation is the role of the Creator in creating and managing the world. Therefore, it is the aim of humans to manage the world in an orderly manner. The purpose of education in Genesis 2 is to enable humans to serve the world.

There are many students in school. So school safety accidents are happened by accident. But, if teachers know and understand about school safety accidents exactly, the school safety accidents can be reduced. The conclusion of this study is as follow. First, generally teacher has a duty and responsibility to protect and care students in educational activities. And teacher has a responsibility to protect and care students only in the cases of predictability. Second, teacher must do his/her best about a duty of attention. If teacher do his/her best about a duty of attention, he(she) has not the responsibility about the accident. Third, teacher needs to have more concern student who has a controversial figure. And teacher needs to have an evidence that he/she did his/her best for the student ordinary times. Fourth, the criteria of teacher's legal or illegal punishment to students is (1) the motivation and details for punishment, (2) the methods and degree for punishment, (3) a part of body for punishment, (4) the degree of damage for punishment. Fifth, teacher need to learn the program about school safety accidents systematically.

This descriptive study was conducted to examine the factors affecting core competency, learner motivation, and learner satisfaction of nursing students and to develop effective teaching methods. The subjects of this study were 134 nursing students. The core competencies of nursing students were higher in 3rd grade than in 2nd grade, and the core competency, motivation, and learner satisfaction of the nursing students were higher than those of below average students. The explanatory power of a core competency model constructed using the self-directed learning readiness, teacher-student interaction, and academic achievement was 45.1%. Additionally, the explanatory power of a learner motivation model based on self-directed learning readiness, teacher-student interaction, academic achievement, and learner motivation was 47.5%, while that of a learner satisfaction model constructed using the teacher-student interaction and learner motivation was 43.4%. In conclusion, it is necessary to improve teacher-student interaction and self-directed learning readiness to increase core competency and learner motivation. To increase learner satisfaction, it is necessary to intervene to encourage learner motivation and to make the teaching-student interaction efficient.

The purpose of this study was to apply the coteaching to the teaching practice of the student-teachers and identify the distinctive characteristics of the communication processes appeared in coteaching. We developed the semiotic analyzing-frame and observed 7 classes of middle schools where the student-teachers cotaught one or two units. Then we analyzed the communication processes on the view of semiotics. We found three patterns of the communication processes. First, when there was a discontinuous communication between the student-teacher and the students, the communication was restarted by the other student-teacher leading to the complete meaning making. Second, when an insufficient communication took place by the student-teacher using inadequate interpretant, the other student-teacher modified the communication by selecting another interpretant including sufficient meaning towards the object. With this new interpretant, students could refine the imperfect private meanings and eventually establish the more objective meanings. Third, the communication was pre-planned between coteachers to help students understand the contents through the successful translation of interpretants. Coteaching provided positive implications to improve the communication processes in science lesson.

This study was to examine the effects of teacher's encouraging language on elementary student's adjustment to school life. To achieve this purpose, teacher's encouraging language were drawn from Adlerian literatures and ten principles of encouragement were established as the following: recognizing the student's values and potentials, putting an emphasis on student's positive sides, helping the student realize his or her own strength, tolerating student's mistakes, using perceptual alternatives, practicing self-encouragement, accepting and supporting opponents, stimulating internal motivations, and emphasizing social usefulness. Subjects were 34 1st graders at J elementary school in CheonNam. 17 subjects were assigned to experiment group and 17 subjects were assigned to control group. Teacher's encouraging language were applied to experiment group and teacher's usual languages were provided to control group for ten weeks. The quantitative data were collected through Elementary school adjustment behavior rating scale(Oh, 2009) and were analysed via ANCOVA. The qualitative data were collected through observations and products of the subjects and were analysed via qualitative methods. The results showed that teacher's encouraging language had a positive effect on the student's adjustment to school life.

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.
