이 연구는 개정된 물리교과서에 포함된 현대물리학 소재인 특수 상대성 이론에 대해 고등학생의 인지 수준을 고려하고 학습자의 주도적 수업참여를 구현하기 위하여 '가상현실'과 '사건도표' 활동이 포함된 수업방법을 고안하여 그 효과를 정량적이고 정성적으로 분석하는 데 목적이 있다. 특수상대론 개념 학습 프로그램을 통한 수업과 전통적 수업은 선택 후 설명식 문항의 전반적인 성취도에서 유의미한 차이를 나타내지 않았다. 프로그램 수업을 이수한 학생은 복합 개념 형 문항의 성취도는 유의미하게 높게 나타났다. 특수 상대론적 역설문제에서는 프로그램 수업집단은 전통적 수업집단보다 통계적으로 유의미하게 높은 성취도를 나타내었다. 프로그램 수업집단 학생들은 역설문제 해결과정에서 특수 상대론적 현상을 좌표계의 틀 위에서 객관적으로 설명하는 좌표계 의존 형 문제 해결방식의 특성을 나타내었다. 전통적 수업집단의 학생들은 특수 상대론적 현상을 불완전하거나 잘못된 좌표계 개념으로 설명하였고 사건의 순서를 관찰자의 직관에 의존하여 판단하는 관찰자 의존형 문제 해결방식을 나타내었다. 특수 상대론적 효과가 시각화된 영상을 보고 사건도표라는 가상의 시공간을 노트에 그려보고 생각하는 활동은 학생들에게 도약판을 만들어 주는 하나의 방법으로 제안한다.

The purpose of this study through ethnographic inquiry is to describe how an elementary teacher teaches mathematics with understanding. The ways that teachers'beliefs affect instructional activities, what means understanding from the view of cognitive psychology, and ethnographic research tradition were reviewed to anchor theoretical background of this study. A third-grade teacher and his 45 students were selected in order to capture vivid and thick descriptions of the teaching and learning activities of mathematics. Three major sources of data, that is, participant-observation with video taping, formal and informal interviews with the teacher and his students, and a variety of official documents were collected. These data were analyzed through two phases: data analysis in the field and after the fieldwork. According to data analysis, ‘teaching mathematics with understanding’ was identified as the teachers central belief of teaching mathematics. In order to implement his belief in teaching practices, the teacher made use of three strategies: ⑴ valuing individual student's own way of understanding, ⑵ bring students' everyday experiences into mathematics classroom, and ⑶ lesson objectivies stated by students. It is suggested for future research that concrete and specific norms of mathematics classroom for the improvement of mathematics understanding are needed to be identified and that experienced and skillful teachers' practical knowledge should be incorporated with theories of teaching mathematics and necessarily paid more attention by mathematics educators.

본 논문은 학교수학에서 다루어지고 있는 매개변수 개념의 교수-학습에 관한 논의이다. 우리나라 수학교과서에서 매개변수 개념은 중학교 수준의 학습내용과 관련된 대수적 표현에서 자주 다루어지고 있음에도 불구하고 그 개념에 대한 용어 정의는 고등학교 선택교육과정 교과서에서 비로소 도입되고 있기 때문에 매개변수개념 이해를 위한 수학교사의 교수학적 노력이 요망된다. 본 논문에서는 학교현장에서 매개변수 개념의 지도를 위한 교수학적 시사점을 이끌어 내기 위해 매개변수의 개념 정의를 분석하고 우리나라 수학과 교육과정상에서 매개변수가 도입되는 맥락을 외국의 사례와 비교해서 검토한다. 또한 선행연구를 통해 대수학습의 관점에서 매개변수 개념 이해의 중요성을 확인하고 매개변수 개념이 학교수학에서 의미 있게 다루어져야 할 학습맥락에 대해 논의해 본다. 마지막으로 본 논문의 연구내용을 종합하여 매개변수 개념의 교수-학습을 위한 시사점을 요약하여 제시한다.

It is necessary for lower grade students to study the correct usage of tools as a base of the technical education for dismantling and assembling various machines. However, enough understanding has not been obtained though the usage of these tools when training first grade students. So, we started to develop a teaching text and materials within the students' practice curriculum based on the dismantling and assembly of all-terrain vehicle [ATV]'s, which is a very motivating for lower grade students. This practice makes the student learn both how to use the tools and the steering mechanism of cars through the dismantling and assembling of the ATV. It is possible to not only have the student learn about the knowledge obtained through the practice, but also they also acquire wider and deeper knowledge through making the text and teaching materials for the practice. The textbook and secondary educational materials of this practice curriculum were created in cooperation with a fifth grade student as part of their graduation research. As a result, an effective teaching and learning text and secondary educational material regarding manufacturing practice could be developed from the student's point of view. Making a teaching text and materials is effective for promoting the study and experience of engineering.

Purpose - This study investigated the effects of lectures in the English medium (EML) on understanding and learning outcomes. Sixty percent of EML lectures in Korea also use Korean for further support. Thus, this situation needs to clearly distinguish the specific impacts of the EML classes on learning outcomes. Here, we use the same English materials, including PowerPoint slides and video content, given in the Korean and English lectures. The difference between the lectures becomes only whether the lecture is delivered in Korean or English. Thus, we can clearly identify whether the language difference makes any difference in learning outcomes. Research design, data, and methodology - Our sample consisted of 91 students taking an international business course the spring of 2015. All course materials, including textbooks, PowerPoint slides, exams, video, and support content, were presented in English. Survey data and exam results were used. Students filled out their student identification number and name, so we could match the surveys against the exam results. Results - First, results show that whether the lecture was delivered in English or Korean was an important factor when students chose the class. Second, English proficiency related to international business and general English levels were higher in the English class than in the Korean class. However, the understanding of key concepts and reading abilities of international business newspapers were the same for students in both classes. Third, teaching materials and lectures were the most important material for the understanding of key concepts in the business major. Fourth, the exam results showed no difference in performance of the students in the English versus the Korean class. This shows that EML classes were not necessarily detrimental to the understanding of major concepts of the lecture. Thus, it is important that researchers carefully design empirical settings to study the effectiveness of EML. Conclusions - The English lecture can be as helpful for enhancing knowledge in the business major as the Korean lecture. For further research, various English lecture forms can be considered to distinguish the effects of the English lecture.

In nursing, a practice discipline, it has been argued whether the mastery of clinical competence depends on types of learning styles, learning experience, and the use of specialized skills. All these problems are not limited to nursing education. Later educators identified the importance of reflective learning which is a vital element in any form of learning and that teachers and students need to consider how they can incorporate some forms of reflection in the courses. The purpose of this study is to review educational articles for understanding better what reflection in learning is, to identify the theme which is of important relevance to professional practice, from the book, Educating the reflective practitioner, and to discuss the theme within nursing education. Reflection in learning was defined by Dewey(1933) as the process which is involved the perception of relationships and connections between the parts of an experience. This experience is passed on when two people becoming involved with each other in a conversation. schon(1987) emphasized that learning conversation, which is a part of the interaction of student and teacher, is an important factor of the process of reflection-om-actopm. In clinical nursing education, good relationships between teacher and student, faculty's role, interpersonal skills are critical in learning conversation. Then Practing nurses who accept the need to choose nursing actionss on the basis of reflection, who accepet the necessity for understanding and being able to communicate the reasons for action are a powerfful force for the development of nursing into an increasingly more effective profession for the benefit of patients.
