Objective: The purpose of this study was to explore the structural analysis of the relationships among principals and fellow teacher's emotional support, teacher's active motivation for choosing the teaching profession, self-leadership, and child care efficacy and commitment. Methods: Data were collected from 465 child care teachers and analyzed by means of structural equational modeling(SEM). Results: First, principals and fellow teacher' emotional support was found to have a direct effect on teacher's child care commitment, as well as an indirect effect through teacher's self-leadership. Second, teacher's active motivation for choosing the teaching profession was found to have a direct effect on teacher's child care commitment, as well as an indirect effect through self-leadership and child care efficacy. Third, teacher's self-leadership was found to have a direct effect on teacher's child care commitment, as well as an indirect effect through child care efficacy. Fourth, teacher's child care efficacy was to found have a direct effect on teacher's child care commitment. Conclusion: These results suggest the need for a great deal of utility to improve teacher's child care commitment.

본 연구에서는 2009 개정 교육과정에 따른 수학과 교육과정에서 도입한 미분방정식 지도를 위한 수학적 모델링을 소개한다. 2014년에 1개 출판사만으로 출간된 '고급수학 II'의 교과서는 이계미분방정식 y"+y=0의 풀이를 거듭제곱 급수 방법을 사용하고 있다. 이에 따른 문제점을 알아보고 그 대안을 제시한다. 또한, 고급수학 II 교과서는 기계적 시스템을 다루고 있지만 전기적 시스템은 다루지 않고 있다. 따라서 교과서에서 다루는 일 계미분방정식을 전기회로로 지도하는 방안을 제시한다. 끝으로 미분방정식 지도와 관련된 용어를 제시한다.

The purpose of this study is to further develop the strategies using science magic and investigate the their effects of the instruction on the student's attitude toward science. To do this, a main idea was selected and stages for science teaching methods were developed. Two classes of the 4th grade were selected and instructed. After implementing and using the teaching method, a test and survey were administered to examine the perception of the students and the learning effects of the new science teaching. The results of this study were as follows. First, the strategy for using science magic was developed and applied. For learners, doing science magic was more effective on their own in terms of boosting student's understanding and interest. Also the teacher's modeling was better in terms of presenting the contents. Second, the students' reaction and perception on using the science magic in classes were positive. In the classroom setting, science magic helped the learners understand better and made the learning environment fun. Third, instruction using science magic had a positive effect on student's attitude toward science. Students felt curiosity about science magic. It made them participate better in studying the activity as well. In conclusion, instruction using science magic can be applied to science to education, and the attitudes toward science and learning achievements can be improved.

Objective: Using data from the Panel Study on Korean Children, this study investigated the influence of teacher'thoughts about the transition from ECEC to primary school in relation to learner-centered teaching methods and children's school adjustment. Methods: We analyzed the longitudinal data of 658 seven-year-olds from the 8th and 9th waves of the panel study of Korean children collected by the Korea Institute of Child Care and Education in 2015 and 2016. The main analysis method was Structural Equation Modeling(SEM). Results: First, theachers' thoughts about the transition from ECEC to primary school was noteworthy. Second, the more concern a theacher' had about transition, the higher their learner-centered teaching method. Third, teacher' concern about transition influenced children's school adjustment. Fourth, a teacher's learner-centered teaching method mediated concern about children's transition and school adjustment in the first year and the second year. Conclusion/Implications: According to the results of this study, 1st grade teachers' concern about the transition from ECEC to primary school has been found to be predictors of children's school adjustment.

This paper details case study vignettes that focus on enhancing the teaching and learning of geometry and measurement in the elementary grades with attention to pedagogical practices for teaching through problem solving with rigor and centering equitable teaching practices. Rigor is a matter of equity and opportunity (Dana Center, 2019). Rigor matters for each and every student and yet research indicates historically disadvantaged and underserved groups have more of an opportunity gap when it comes to rigorous mathematics instruction (NCTM, 2020). Along with providing a conceptual framework that focuses on the importance of equitable instruction, our study unpacks ways teachers can leverage their deep understanding of geometry and measurement learning trajectories to amplify the mathematics through rigorous problems using multiple approaches including learning by doing, challenged-based and mathematical modeling instruction. Through these vignettes, we provide examples of tasks taught through rigorous problem solving approaches that support conceptual teaching and learning of geometry and measurement. Specifically, each of the three vignettes presented includes a task that was implemented in an elementary classroom and a vertically articulated task that engaged teachers in a professional learning workshop. By beginning with elementary tasks to more sophisticated concepts in higher grades, we demonstrate how vertically articulating a deeper understanding of the learning trajectory in geometric thinking can add to the rigor of the mathematics.

The article focuses on the areas of education activities in using techniques for teaching and learning with information and communication technologies (ICTs), researching and analyzing the available ICTs, gearing the technologies to the specific psychological and pedagogical conditions, independently building and modeling ICTs, enlarging and developing their use in the learning environment. The visualization of scientific research has been determined to be part of the educational support for building students' ICT competence during teaching and learning and is essential to the methodology culture. There have been specified main tasks for pedagogy technologies (PTs) to develop the skills of adaptability to the global digital space in students, their effective database operation and using the data bases as necessary elements for learning and as part of professional training for research. We provided rationalization for implementing the latest ICTs into the Ukrainian universities' curricula, as well as creating modern methods for using the technologies in the learning / teaching process and scientific activities.

Computer aided process planning and Offline programming are decisive factors in successful implementation of automated robotic production. However, conventional offline programming procedure has proven ineffective due to time-consuming teaching process for robot programming and due to inefficient system modeling. The paper presents an efficient procedure to semi-automatically generate robot job programs for ship block welding applications. In the research, the teaching positions are automatically determined by predefined rules which are functions of the type and the dimensions of the given welding section of ship block. And a sequence of robot movements and welding conditions such as welding type, welding current, welding speed, and welding torch orientation, are determined by use of Standard Program which is experimentally proved to work well for the welding wection group. Finally, a robot program for the welding section is generated automatically. Based on the algorithm, a offline automatic teaching software is developed. The paper presents also the algorithm and structure of the software.

본 연구는 수학적 모델링 활동을 수행할 수 있는 과제 개발과 이를 기반한 수업 설계의 중요성을 생각하여, 수학적 모델링에 대한 예비교사들의 내재된 인식을 바탕으로 그들이 설계한 수학적 모델링 기반 수업의 특징을 파악하는 데 목적이 있다. 그 결과 예비교사들이 개발한 수학적 모델링 과제는 주로 개념 활용 학습을 목적으로, 실생활 맥락의 소재를 활용한 적정량의 정보를 제시한 다소 구조화된 형태로, 이해, 의미, 개념과 연결이 있는 절차적 과정이 필요한 인지적 요구수준으로 개발된 경향을 보였다. 이를 바탕으로 설계한 수업은 대부분이 준비 활동, 모델 도출 활동, 모델 탐험 활동만을 유도한 경향이 있었다. 본 결과를 토대로 예비교사 교육에서의 시사점을 논의하였다.

이 연구는 보육교사가 지닌 과학교육지식과 과학에 대한 태도가 과학교수 불안에 미치는 영향을 살펴보기 위해 실시되었다. 보육교사 259명을 대상으로 수집한 자료는 PASW 18.0과 AMOS 7.0을 이용하여 Pearson의 적률상관관계분석과 구조방정식을 통해 분석되었고, 주요결과는 다음과 같다. 첫째, 보육교사의 과학교육지식, 과학에 대한 태도 및 과학교수 불안 정도는 모두 중간수준 이상인 것으로 나타났다. 둘째, 보육교사의 과학교육지식, 과학에 대한 태도는 과학교수 불안과 상관이 있었다. 셋째, 보육교사의 과학교육지식은 과학에 대한 태도에 직접적인 영향을 미쳤고, 과학교육지식의 영향을 받은 과학에 대한 태도는 과학교수 불안에 직접적인 영향을 미치는 것으로 나타났다. 보육교사의 과학교수지식과 과학에 대한 태도가 과학교수 불안에 미치는 영향은 전체 분산의 57%를 설명하는 것으로 나타났다. 이러한 결과는 보육교사의 과학교수 불안 수준을 낮추기 위해서는 보육교사의 과학교육지식, 과학에 대한 태도를 향상시켜야 함을 시사한다.
