In this study the interpretive perspective means a point of view on educational curriculum in which in order to reach the understanding of the meaning of the behaviors and beliefs of human beings, and the historical and cultural products, the process of discussing on the basis of historical and cultural knowledge is very important. The developed curriculum means the one that consists of the goal of the curriculum, the contents of the curriculum, lesson plans, and the instruction-learning materials. This study has been carried out in four steps: conceptualization, development, application and evaluation. This study has tried to propose some changes in the contents of clothing life education on the basis of the interpretive perspective by firstly, assuming some core concepts that were related to clothing life education in Home Economics and secondly, organizing the contents of the clothing life culture area based upon historical and cultural materials. The results of the application of the developed curriculum came out positive. The strong points of the developed curriculum showed that for the students the curriculum was helpful in seeking answers to such questions as 'who I am' and 'what kind of being I am' through the perception of traditional culture and clothing life. In addition, the developed learning contents were recognized as new knowledge. It also showed that teaching contents with a focus on the interpretive perspective could play a role as reflection for the practice and for the arrival at the final perception. A weak point of the developed curriculum is that the Home Economics teachers themselves might find difficulty preparation for teaching this material because of their limited understanding and knowledge of the historical and cultural materials about clothing life.

In the 7th-curriculum, only basic arithmetics of complex numbers have been taught. They are taught formally like literal manipulations. This paper analyzes mathematically essential relations between algebra of complex numbers and plane geometry. Historical analysis is also performed to find effective methods of teaching complex numbers in school mathematics. As a result, we can integrates this analysis with school mathematics by help of Viete's operations on right triangles. We conclude that teaching geometric interpretation of complex numbers is possible in school mathematics.

수학학습장애는 독해장애와 더불어 학습장애의 주요영역으로 인식되고 있다. 그러나 독해 장애에 대한 연구와 비교하였을 때 상대적으로 주목받지 못한 분야로, 과연 수학학습장애는 무엇이며, 수학학습장애 아를 판별하는 기준을 어떻게 설정할 것인가의 문제가 여전히 논란이 되고 있다. 본고에서는 수학학습장애에 대한 최근의 세 가지 관점-신경학적 관점, 발달심리적 관점, 교육적 관점-의 고찰을 통해, 수학학습장애를 진단하기 위한 하나의 통합적 관점이 필요함을 제안하고 있다. 이것은 수학학습장애를 신경적 결함으로만 해석하려는 전통적 관점에 대한 발달심리학자들의 비판을 수용한 것이며, 오늘날 파행적인 교육체계에서 희생되고 소외되어온 학생계층을 포용하기 위한 한 가지 제안이 될 것이다.

역사의 시작은 어디인지 아득하지만 일반적으로 문헌을 통한 과학적인 신뢰성을 갖게 되는 실질적인 방법이 원칙이다. 하지만 이런 연구가 거의 전무한 우리 수학의 뿌리에 대한 연구는 문헌 연구가 그 기반을 이룰 것이다. 따라서 본 연구자는 우리 역사의 뿌리를 수학적 관점에서 한 분야로서 여러 기존의 문헌을 중심으로 특히 사학 연구를 활용하여 수학의 뿌리를 찾으려고 하며, 민족 신화(단군신화) 이전의 경전인 천부경(天符經)의 사상을 기초로 한 동양 사상과 철학의 배경으로 그 위상을 세우고자 한다. 결코 우리 민족의 우수성과 고난의 시절에서 많은 상황적 변화로서 와전되어 있는 부분도 있지만 이를 해석한 여러 문헌을 논리적으로 체계화하려는데 초점을 두고 있다. 주로 신라 시대의 석학인 최치원 선생에 의해 천부경 81자의 한자로 구성되어 해석한 사실에 주목해야한다. 특히 한민족의 언어가 아닌 한자로 우리의 언어와 사상이 기록되어 있고, 이 민족의 침입으로 인한 민족 문화의 말살이 걸림돌이 되고 있다. 그럼에도 불구하고 현재에 어려움을 인식하고 연구가 수행되었음을 부인할 수 없다. 따라서 본 연구는 우리 민족 수학의 뿌리를 찾아 민족의 수학사를 인식하는 계기를 주고, 자주적인 민족 정서의 수학 교육에 첫 걸음을 내딛는데 연구의 필요성과 목적이 있다.

This essay is a critical study of the three models of practical theology that emerged in the second half of the 20th century: the critical correlational model (Sherrill, Browning), the hermeneutical model (Groome, Gerkin), and the faith community formation model (Westerhoff, Campbell). This essay first explores the central ideas of practical theologians who adhere to each of the three models and focuses on Christian education, pastoral counseling, and homiletics. This essay then critically evaluates the three models in accordance to the following four themes: how practical theology has 1) responded to the challenges of postmodernity, 2) engaged in dialogue with different types of theology, 3) participated in interdisciplinary dialogue, and 4) understood Christian practice. In conclusion, this essay suggests that the essential tasks of contemporary Christian education as practical theology include: 1) providing an active response to many challenges of postmodern, postsecular, postdigital, and posthuman era, 2) engaging in interactive dialogue with diverse forms of theology, and 3) facilitating interdisciplinary dialogue based on transversal rationality, and 4) establishing of the concept of Christian practice at the individual, ecclesial, social, public, ecological, and digital levels.

학생들이 실세계와 수학적 세계사이를 연관시켜 사고하고 해석하는 방법 및 실제 문제를 해결하는 일반적인 전략의 방법론의 하나가 수학적 모델링(Mathematical modelling)이라고 볼 수 있다. 한편, 수학 교수 ${\cdot}$ 학습 과정에서 구체적인 조작 활동을 통하여 학생 스스로가 지식을 ‘구성(construction)’ 할 수 있도록 해 주어야 한다는 구성주의적 사조가 대두되고 있는데, 본 논문에서는 구성주의적 관점에서 수학적 모델링을 통한 수학 교수 ${\cdot}$ 지도를 위한 활용 방안을 한 예시를 통해서 고찰해 보고자 한다.

Inventive mathematical thinking, original mathematical problem solving ability, mathematical invention and so on are core concepts, which must be emphasized in all branches of mathematical education. In particular, Polya(1981) insisted that inventive thinking must be emphasized in a suitable level of university mathematical courses. In this paper, the author considered two cases of inventive problem solving ability shown by his many students via real analysis courses. The first case is about the proof of the problem "what is the derived set of the integers Z?" Nearly all books on mathematical analysis sent the question without the proof but some books said that the answer is "empty". Only one book written by Noh, Y. S.(2006) showed the proof by using the definition of accumulation points. But the proof process has some mistakes. But our student Kang, D. S. showed the perfect proof by using The Completeness Axiom, which is very useful in mathematical analysis. The second case is to show the infinite countability of NxN, which is shown by informal proof in many mathematical analysis books with formal proofs. Some students who argued the informal proof as an unreasonable proof were asked to join with us in finding the one-to-one correspondences between NxN and N. Many students worked hard and find two singled-valued mappings and one set-valued mapping covering eight diagrams in the paper. The problems are not easy and the proofs are a little complicated. All the proofs shown in this paper are original and right, so the proofs are deserving of inventive mathematical thoughts, original mathematical problem solving abilities and mathematical inventions. From the inventive proofs of his students, the author confirmed that any students can develope their mathematical abilities by their professors' encouragements.

Gender might be interpreted in different roles and meanings depending on social and cultural backgrounds. Based on the premise that understanding of gender may change the direction of mathematics education, this paper confirmed how gender is interpreted in the preceding study of mathematics education in Korea by applying the literature research method. In particular, predictive model based on empirical perspective and gender schema model based on constructivist perspective. Based on the analysis of gender and research methods in cultural and historical composition models based on historical perspectives and postmodernism models based on postmodernism perspectives, this study analyzed trends in domestic mathematics education. As a result of the analysis, it is confirmed that gender is recognized as a biological difference in domestic mathematics education, and that analysis of gender and related elements of mathematics education is mainly used using statistical analysis techniques. This suggests that various approaches to interpreting gender's role in future mathematics education are needed. The existing mathematics education research on gender is composed in terms of gender differences. Since biology at the time did not explain this difference, however, it should now be based on the concept of gender, which is socially defined gender. Accurate understanding of gender and gender can be the basis for clearer understanding and interpretation of gender-related mathematics research.

In the 2009 revised science curriculum, comprehensive verbs such as 'know (38%)' and 'understand (46%)' are used in more than 80% of the achievement standard. Many readers, such as teachers, textbook makers, etc. have difficulties in interpreting the meaning of achievement standard sentences with these comprehensive verbs. On the other hand, 'Trends in International Mathematics and Science Study (TIMSS)' uses more various and specific verbs to express the cognitive domain. In this study, we analyzed the 2009 revised science curriculum achievement standard focusing on the TIMSS cognitive domain assessment framework. We divided achievement standard to 228 sentences and three teachers analyzed the meaning of verbs in achievement standard. There were two main results of this study. First, the verb 'Know' was analyzed into different kinds of meanings, such as 'Describe (27%)', 'Recall/Recognize (25%)' and 'Relate (17%)', etc; and the verb 'Understand' was analyzed into 'Explain (37%)', 'Relate (27%)' and 'Describe (21%)', etc. Second, there appeared to have a disagreement among the three analysts during the process of interpreting the achievement standards when the level and scope of the contents of each grade is not clear. This study concludes that there's a need for continuous discussion on the use of verbs in achievement standard to promote clearer expressions for better understanding.

This study analyzed the difficulty trend of item which are common with TIMSS 1999, 2003, 2007 and are released since TIMSS 2007. The results show that the 7th curriculum has positive effects on the students' achievement in the domain such as spatial sense of rotation, ratio proportion percent, pattern, calculation of decimal numbers, concept of angle, area of triangle, and qualitative approach to graph. And the results leaved the consideration for the process of scoring, teaching method of statistical probability concept, and making table as a problem solving method.
