The purpose of this study is to investigate the duties of teachers working at secondary level technical vocational education institutes, and analyze job importance, difficulty and frequency of performance perceived by teachers. For deducing the duties of teachers working at secondary level technical vocational education institutes, they were theoretically devised by reviewing related legislations & regulations and domestic & overseas literatures. The devised duties were reviewed by 16 current teachers and 3 education experts to be revised and supplemented to complete the job model. Based on this, development of research tool was finalized, and questionnaires were used as the research tool. The results of this study are as follow. First, the job categories of teachers working at secondary level technical vocational education institutes consisted of 7 categories that are subject instruction, student instruction, class management, curriculum organization & administration, school affairs & administrative duties, PR & field practical training and expertise enhancement. Based on the CFA, they consisted of 46 sub-factors in 10 categories with 3 categories of lesson preparation & planning, lesson administration and academic evaluation for subject instruction, and 2 categories of extracurricular student guidance and school life guidance for student instruction, and class management, curriculum organization & administration, school affairs & administrative duties, PR & field practical training and expertise enhancement. Second, job importance perceived by teachers working at secondary level technical vocational education institutes was found to be high overall with 4.10, while above average in difficulty with 3.45 and average in frequency of performance with 3.12 (1-3 times a month). As for categories with high job importance, they were found to be in the order of academic evaluation (4.32), lesson preparation & planning (4.28), expertise enhancement (4.27), lesson administration (4.26), school life guidance (4.25), class management (4.17) and PR & field practical training (4.12). In regards to categories with high job difficulty, they were found to be in the order of PR & field practical training (4.07), curriculum organization & administration (3.73), expertise enhancement (3.55), school life guidance (3.48), academic evaluation (3.35) and extracurricular student guidance (3.22). As for categories with high frequency of job performance, they were found to be in the order of class management (3.88), lesson administration (3.77), school life guidance (3.52), school affairs & administrative duties (3.40) and lesson preparation & planning (3.17).

2003년 미국 IT기업인 린덴랩에서 개발한 3D 가상현실 사이트인 세컨드라이프가 최근 인터넷 서비스 시장에서 큰 주목을 받고 있다. 그 까닭으로는 세컨드라이프가 3D 기반 인터넷 기술과 사용자의 서비스 경향을 충실히 담고 있다는 점과 현실과 밀접히 연결되는 부분을 많이 가지고 있어 현실 세계에 미치는 영향력이 점점 증가세에 있다는 것을 들 수 있다. 최근의 우리나라 교육 현장에서는 다양한 ICT활용 교육을 통하여 학교에서 이루어지는 교과 지도와 생활 지도를 온라인으로 확장하고 있으며, 또한 기술의 발달에 힘입어 모바일 교육과 U-Learning과 같은 새로운 교육 방법과 함께 온라인에서 주목받는 우수한 소프트웨어를 학교현장에 도입하려는 노력을 시도하고 있다. 본 연구에서는 Second Life가 머지않아 교실수업과 인터넷수업을 잇는 매개체로 사용될 것이라 보고 세컨드라이프의 국내외 적용사례를 살펴보고 초등교육에서 활용하기 다양한 방안을 제시하고 장단점을 분석한다.

In this paper we introduce mathematical modellings in teaching and learning differential equations which were adopted by 2009 revised curriculum. The textbook of 'Advanced Mathematics II' published in 2014 with one publisher includes the content of the second order differential equation y"+y=0 by the power series method. This paper discusses the issue of the power series and gives an alternative method to explain problems of differential equation. Also, we found that the textbook of 'Advanced Mathematics II' used the mechanical system not electrical system in solving differential equation problems. Thus this paper suggests a method using an electric circuit in teaching and learning the first order differential equation. Finally we suggest some terminologies in the teaching and learning of differential equations.

Classification is presented in the curriculum of elementary school mathematics, science, Korean language, and integrated subjects as the major function that needs to be learned. In addition, mathematics textbooks teach the classification as a basic process for organizing and interpreting collected materials in a separate unit. So, we analyzed the curriculum documents and textbooks of mathematics, science, Korean language, and integrated subjects. And we explored how to teach the classification in the context of mathematics subject. As a result, it is necessary to find different classification criteria in conjunction with detailed observation and investigation activities, and to teach that considering the circumstances and purpose of the classification. It also provided implications on how to revive converged classes that focus on big ideas and skills, which are commonly offered by various subjects.

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.

The purpose of this study is to investigate the problems and conditions of educational guidance and counselling of teachers in the gifted classes. For the study, 267 teachers were sampled from the Gifted Education Institutes of metropolitan and provincial offices of education and Gifted Classes of the school across Korea, and the questionnaire developed by the researchers were administered to them. The results of this study are as follows : First, the 82% of respondents reported that the guidance and counselling in the gifted education is needed. So it demands the active responsive strategies on it. Second, the respondents reported that the selfish or self-centered traits of the gifted students are the most problematic in the gifted classes. It shows the emphasis should be put on the basic life habits and moral education in the guidance and counselling of the gifted education. Third, they pointed out the case-based education is needed for the parents of the gifted to correct their misconceptions about their children. Fourth, to support the teachers of the gifted program, the administrative measures have to be taken, like operation of character education program, forming a consultative group with the experienced teachers, developing the case-based guideline for the guidance and counselling for the gifted education, etc. Fifth, we should develop the Korean model of the gifted education to promote social capital for our future society.

This research has been conducted to investigate the satisfaction level of the learners on after school caring education and the mechanism to improve the drawbacks. In doing so, questionnaire has been carried out on the learners who have finished after school caring education. The results indicates that satisfaction level have been the highest in those who are not married(SD=27.18), has graduated high school(SD=25.55), earn between 2mil and 3mil Won a month(SD=27,42), participate in the program through internet(SD=25.91) respectively. In addition, there have not been significant differences in the level of satisfaction according to motivating factors including benefits for obtaining certificate(SD=27.12), benefits for finding job(SD=26.76), benefit for leisure activity(SD=26.20) and benefit for promotion(SD=24,32). These results imply that there needs to be educational facility and program which can satisfy the learners.

증명은 수학에서 기초적이고도 중요한 주제이다. 추측을 만들어내고 자신에게는 물론 타인에게까지 그 추측을 정리로서 확신시키는 활동은 수학활동에서의 핵심이라고 할 수 있다. 그러나 현재의 증명 학습지도에서는 학생들의 수준보다는 높은 증명 발달단계를 제시하고 있다는 보고와 함께 기존의 지도방법의 개선책을 요구하고 있다. 따라서 본고에서는 몇 가지 증명의 발달 단계를 정리해 보고 Balacheff의 증명 4단계를 토대로 하여 증명활동을 점진적인 구성으로 제시한다.
