  • 본 연구는 사회문화적 관점에서 지식의 생산자이자 소비자인 과학교사의 학습과정을 전 생애에 걸쳐 살펴보고 이를 바탕으로 과학교사의 실천적 지식의 형성 및 발달 과정을 탐색하고자 한다. 이를 위하여 수년 동안 대학 및 대학원에서 수업 및 세미나를 함께 하면서 예비 교사 혹은 교사로서의 삶을 가까이에서 지켜 볼수 있었던 두 명의 과학교사를 연구 참여자로 최종 선정하였다. 이들은 교직경력 3년에서 6년의 중학교 과학교사로 각자 상이한 삶의 맥락을 토대로 과학교사로서 전문성을 발달시키며 실천적 지식을 형성해 나가고 있었다. 연구 참여자의 삶에 대한 심층적 이해와 과학 교사로서 실천적 지식을 탐색하기 위하여 생애사 모델과 실천적 지식의 구조를 분석틀로 사용하였다. 연구 결과 과학 교사의 실천적 지식의 형성 및 발달은 교사 개인의 삶의 맥락에 따라 주요 관심과 비중이 상이하게 달라짐을 확인 할 수 있었다. 이러한 교사 개인의 삶의 여정을 통해 자연스럽게 형성된 과학교사의 실천적 지식은 수업 전문성 향상을 위한 중요한 모티브로 작용하고 있었으며, 교사 개인의 끊임없는 반성과 성찰로 더욱 공고히 발전하는 경향을 보였다.

  • Purpose: The purpose of this study is to investigate the improvement measure of dental technician practical examination. Methods: A survey was performed on 111 dental technicians who were self-written questionnaire. The results were analyzed by SPSS 12.0. The collected data was analyzed by frequency and chi-square test. Results: Questions most necessary work tools with the articulator was the highest with 55.9%, Electric wax carver(16.2%), heating clear(14.4%), CAD/CAM program(9.0%) was in the order. The need for additional practical test in response to actions included maxillary and mandibular comments occlusal work that you have to wax up the highest rate of 63.8%. Items most in need of improvement was strengthen of clinically oriented(48.0%), separation of written and practical(14.6%), control the degree of difficulty(11.4%) were the next order. Conclusion: Based on the results of this study, the current dental technician did not show major problems in the practical test. However, clinicians should be strengthened mainly. To do this, the use of the articulator is essential.

  • This study developed an integrative curriculum design plan for Home Economics through a deliberation method. This study established a research framework to integrate the deliberation models of Schwab, Walker, and Reid that inherited the intellectual tradition of curriculum deliberation along with the practical reasoning process of Brown and Paolucci from a critical science perspective. The practical research problem was formulated as "What should be done to develop a Home Economics integrative curriculum?" To address this practical research problem, deliberation with deliberators of each small, medium, and large groups was processed for the development of integrative curriculum design plans. An initial proposal was developed from small group deliberation processes. An initial proposal was examined and an alternative plan was developed from medium group deliberation processes. An alternative plan and its consequence were re-examined from large group deliberation processes. The authors finalized a proposal organized on four valued ends of self-formation, intersubjectivity, social action, and life skills. A practical problem focused integrative curriculum was developed and proposed to pursue the four valued ends. The suggested final practical problem focused curriculum demonstrates the power of Home Economics to contribute to the advancement of individuals, families, and society as well as the practical empowerment of students.

  • Purpose: The purpose of this study is to investigate the improvement measure of dental technicians practical examination system. Methods: The subjects in this study were 290 dental technicians who were self-written questionnaire. The results were analyzed by SPSS 16.0. The collected data was analyzed by frequency and chi-square test. Results: Dental technician practical exam feasibility of survey were largely negative views. Articulators work required in practical exam as a tool used (28.7%), electric wax carver (19.5%), heating clear (17.8%), handpiece (16.2%) had a response. Dental Technician positions in accordance with practical exam in comparison to satisfaction, the professor is satisfied, but the clinical dental technicians were generally dissatisfied (p<0.05). Conclusion: Based on the results of this study, Current is necessary to analyze the practical test. It also should be compared with foreign institutions. Long-term and short-term improvement examination system that can be applied to the improvement of the dental technician to draw practical test it is necessary to improve the system.

  • Objectives : The purpose of this study was to examine the problems with the current practical examination, to suggest some of the right directions for that and to facilitate the improvement of the exam. Methods : The subjects in this study were the selected professors involving professors in charge of practice and the selected clinical dental hygienists who had ever served as the graders of the national practical exam. Results : A direct practical test was required in the national practical exam (77.3%), and educational facilities(79.2%)(p<0.05). They didn't put confidence in the national practical exam(81.0%) nor viewed the items about the removal and detection of dental calculus as appropriate(58.5%), either. Specifically, the items were considered to be more inappropriate by the professors in charge of practice(74.3%) than by the other professors and clinical dental hygienists(p<0.05). Concerning ways of administering the national exam, the largest group preferred that a professional evaluator should evaluate students in person by visiting their colleges(66.8%). Conclusions : The above-mentioned findings illustrated that both of the dental hygiene professors and the clinical dental hygienists thought the current national dental hygienist practical exam would absolutely be necessary since it exerted a great influence on education and educational facilities, and that the national exam should be improved to gain more confidence, to solve comprehensive problems and to ensure the efficiency of administration.

In addition, the study presents practical limitations of theoretical acceptance sampling by attribute and by variable. Finally, following research also recommends the sampling inspection based on production technology. However, the inspection method requires quality expertise with various experience and implicit knowledge of the field.

  • Purpose: This study aims to make suggestions for the implementation of the job-based dental technician practical exam. Methods: The duties of dental technicians and the recent trends in the dental technician field were defined and identified, respectively, to achieve the purpose of the current study. The practical test system of domestic and foreign national tests was comparatively analyzed to seek improvements. Additionally, the direction of the practical test to be taken in the future was investigated through a public hearing of domestic experts. Results: As a result of this study, the job site of dental technicians was recently found to be undergoing many changes, and it can be observed that related laws and the work site have already changed. Comparison of overseas test systems showed that Korea was limited to a rather small evaluation range; in general, the scope of the evaluation of the practical tests in foreign countries was widely conducted. In the results of the public hearing, opinions exist that the evaluation range of the practical test was expanded and that new subjects were needed, but the opinion on the existence of practical difficulties was mainly mentioned. Conclusion: The evaluation range of the current practical examination subjects should be expanded and the evaluation of digital dental engineering subjects should be added to proceed with the job-based practical examination. However, it seems that efforts should be made gradually through various efforts in the future due to practical difficulties.

  • 본 연구의 목적은 태권도를 전공하는 대학생들의 태권도 내용을 파악하고 전문지식과 실무능력을 향상시키는 것이다. 연구대상은 대학태권도지도자, 국내와 국외 태권도 실무지도자로 하였다. 조사방법은 델파이 조사를 하였고, 1차는 개방형 질문으로 구성하여 실기 능력을 개선하기 위한 개선점을 학교의 개선점과 학생의 개선점으로 구분하였다. 2차 델파이 조사는 학교와 학생으로 구분한 질문에 응답하도록 하였고 Likert 5점 척도를 사용하였다. 3차 델파이 조사 결과 태권도에 대한 전문지식과 전문 실기 능력(품새, 겨루기, 시범)을 갖추어야 하는 필요성과 문제점을 이야기하였고, 그 문제점을 바탕으로 대학에서는 '종목별 전문지식을 쌓을 수 있도록 동기부여 필요' '학생들에게 수련 기회 제공', '다양한 진로 방향을 제시' 등이 나타났다. 학생들의 경우 '전공 종목 이외에 다른 종목의 취업 가능성 인식', '태권도 종목별 우월감을 버리고 소통할 수 있는 노력', '다른 종목을 배워야 하는 필요성 제고' 그리고 '생활체육 태권도 관심 유도 노력' 등이 주요주제로 밝혀졌다. 대학프로그램에 있어서 현장에서 적용·가능하도록 개선해야 할 필요성과 학생들의 인지도 변화가 절실히 필요함을 알 수 있었다.

  • 본 연구에서는 현직 교사가 자신의 생애, 특히 교직입문 이후 경력이 경과함에 따라서 접하게 되는 다양한 경험들 속에서 이루어진 교수실행의 연화과정을 탐색하고자 한다. 이를 위하여 구체적으로 교사의 관점에 근거해 교사의 삶을 살펴보는 생애사적 접근을 취하였고, 실천원리 (practical principle)의 변화 중심으로 개별 과학 교사의 교수실행 변화 과정을 상술하였다. 연구 참여자들은 각각 7년차, 10년차 중등 과학교사로 면담 및 수업관찰을 통해 연구 참여자의 교수실행 특징 및 변화 과정에 관한 자료를 수집하였다. 연구 결과로부터 연구 참여자들의 교수실행 변화과정의 특징을 다음과 같이 도출할 수 있었다. 연구 참여자들의 교수실행 변화는 1) 변화를 촉발한 결정적 경험, 이후 2) 기존 교수실행에 대한 적극적인 반성, 마지막으로 3) 교수실행의 구체적인 변화에 직접적인 영향을 미친 경험들이라는 3 요소의 상호작용을 통해 이해될 수 있었다. 이와 같은 교수실행 변화는 실천원리의 지형 (국면) 변화로 나타났다. 과거와 비교하여 변화원 주요 실천원리의 변화 양상은 (1) 기존 실천원리의 강화, (2) 기존 실천원리의 대체 (3) 새로운 실천원리의 형성으로 대별할 수 있었다.
