In this paper, we study the recognition and fallacy of would-be in-service teachers about numbers with irrational exponent. We chose 51 secondary school teachers who are teaching mathematics in K metropolitan city and investigate their recognition and fallacy about the cases of irrational exponents of a positive rational and irrational exponents of a positive irrational number at the expansion of exponential law. We found following facts. First, in-service teacher's a percentage of correct answers differ depending on the type of numbers with irrational exponent. Second, in-service teachers decide their answer depending on intuition rather than logic. Third, in-service teachers decide their answer depending on exponential rather than base.

This study investigates the process of PCK formation for 2017 novice teachers in Busan. This study was conducted parallel to quantitative research using the H-PCK measurement tool as well as qualitative research methods through an open questionnaire and after-interview. Consequently, the H-PCK level of novice teachers was 3.51. The knowledge of perspective on home economics education (KP) was 3.87, knowledge of home economics curriculum (KC) was 3.37 and the knowledge of home economics instructional strategies (KI) was 3.39. Study participants reported that curriculum knowledge, curriculum content knowledge, and teaching strategy knowledge were formed through preparation for appointment; however, it was not possible to judge if PCK was formed for the restructuring ability or the reconstruction ability. Knowledge related to curriculum content was learned through teacher training, internet teacher community, and internet information materials. Knowledge of teaching strategies was learned through 1-2 teaching consulting or peer scholarship. It is necessary to revise the university curriculum (such as expansion of curriculum education, expansion of experience in teaching practice, and actual case study) order to form PCK. Second, it should be developed and operated various training programs for the formation of home economics education curriculum knowledge. Third, it is necessary to organize a nationwide system to support the mentor. In the future, it is necessary to study PCK analysis for each unit and topic as well as to explain methods that can be provided to field teachers.

The purpose of this study is to gather background data of teacher's performance of the fisheries and shipping industries high schools. This data will provide direction for advancing teacher's performance of the fisheries and shipping business high school,s by investigating and analyzing variables related to teacher's performance. This study focused on the opinions of thirty teachers within the fisheries and shipping business high schools. The conclusions of the study were as follows: First, teachers continually seek goal achievement, rewarding jobs, and a feeling of self-worth. However, it was found that male teachers have stronger task performing ability and form stronger relationships with their partners than female teachers. Second, it was shown that teachers have a much higher percentage of ability to teach. Particularly, male teachers are generally higher than female teacher. Third, it was shown that teachers have a much higher percentage of ability to teach, but it is required that they both get equal participation opportunity as there is a little difference between male teachers and female teachers. Fourth, it was found teachers exhibited a lower percentage rate of ability to manage activities, and required further development of programs for expansion of professionalism of this field.

Purpose: The purpose of this study is to provide basic data for a more reasonable health teacher placement policy sending teachers to more appropriate sites, by analyzing the change process of the health teacher placement standards and the problems caused by an unreasonable placement policy. Methods: This study mainly analyzed relevant research data and existing studies focusing on a literature analysis. Results: To date, the placement policy for health teachers has changed, going through expansion, reduction, and retrogression, since its establishment. The standard, placing health teachers only in elementary schools with more than 18 classes, was created in 1952. Despite the expansion of the role of health teachers and the revision of the school health law in 2007, this standard has been applied to date without modification. In the meantime, there have been many problems caused by inappropriate placement of health teachers. It was difficult for health teachers in large schools to carry out proper health education; and, in many schools, passive health management, such as first aid, health tests, and student health management, was mainly executed rather than active health management. Students in small schools were not even given an opportunity to receive health education and health management owing to the absence of health teachers. Also, compared to teachers teaching other subjects, health teachers have had very unfair placement standards. Conclusion: The placement policy for health teachers, which has been applied to the present, has never reflected social change, the increase of student health issues, and the demand from the school area. Although the role of health teachers expanded with the execution of health education, the current placement standards for health teachers are very unreasonable. Accordingly, it is necessary to review the health teacher placement policy in a reasonable manner and to revise the standards considering the reality.

The expansion of exponential law as the law of calculation of integer numbers can be a good material for the students to experience an extended configuration which is based on an algebraic principle of the performance of equivalent forms. While current textbooks described that exponential law can be expanded from natural number to integer, rational number and real number, most teachers force students to accept intuitively that the exponential law is valid although exponent is expanded into real number. However most teachers overlook explaining the value of exponent of rational number or exponent of irrational number so most students have a lot of questions whether this value is a rational number or a irrational number. Related to students' questions, most teacher said that it is out of the current curriculum and students will learn it after going to college instead of detailed answers. In this paper, we will present several examples and the values about irrational exponents of a positive rational and irrational exponents of a positive irrational number, and study the recognition and fallacy of would-be teachers about the cases of irrational exponents of a positive rational and irrational exponents of a positive irrational number at the expansion of exponential law.

In this study, an analysis of the actual conditions and needs regarding elementary school teacher's levels of cooperation was conducted. This was done from the assumption that it is essential for good communication and cooperation to exist between elementary school teachers and after-school care teachers to provide the most reliable after-school care environment possible. Individual interviews with 6 elementary school teachers were conducted, and the results of the data analysis were as follows. First, the necessity for close communication and interaction between teachers was clearly established, due to the obvious advantages obtained from cooperation on supporting children and improving the teacher's levels of expertise. However, contrary to this, the elementary school teachers in fact did not have very good communication between themselves and the after-school care teachers. Second, the problems in cooperation revealed a degree of disapproval regarding the perceived independence of after-school care teacher's duties, a sense of burden arising from interaction with a large number of teachers, the lack of communication time due to the workload of elementary school teachers, and the lack of material resources. Third, teachers further stated that although they were generally interested in after-school care classes, and showed approval of the role of after-school care teachers, regular meetings, and an expansion of the current messenger systems of communication with after-school teachers are clearly needed.
