수학을 교육하다 보면 느끼는 것 중의 하나가 학생의 이해를 돕기 위하여 수학 내용을 시각적으로 알려주되 그 방법이 쉬운 것을 찾는 것이다. 컴퓨터의 발달과 보급으로 인하여 조그만 노력하면 이것이 가능하다는 것을 보여준다. Visual Basic은 윈도우 컴퓨터 언어로서 배우기가 쉬울 뿐 아니라, 이 언어를 이용하여 윈도우용 실행화일을 쉽게 만들 수 있다. 이번 발표는 수치해석학에서 비선형방정식의 해를 구하는 과정을 그래픽을 이용하여 보여주는 프로그램 작성에 관한 것이다. 이것은 모든 수학의 주제에 이용할 수 있다는 가능성을 보여준다. 또한 이것의 종합적인 개발로 수학 교육에 관한 프로그램을 개발할 수 있다.

MZ는 국제적 환경 생태 지대가 될 수 있으며, 황해의 한-임진 강어귀를 열곡 중심에 있는 철원 유역과 이으며, 동해안 바위투성이 해안에 있는 설악산과 금강산 사이의 태백산까지 잇는다. 이 통일의 자연 기념비는 인류의 희망의 성지와 많은 사람들이 목숨을 잃은 국경 지대에서 평화의 상정이 된 멸종 위기의 학의 보호 구역이 될 수 있다. White-napped 학 (Grus vipio), Red-necked 학 (Grus japonensis), 아시아에서 충성의 상징인 Hooked 학 (Grus monacha)은 곧 멸종할 운명에 처해 있다. 임진강 어귀 근처에서 시작되는 귀중한 풍경은 여러분의 유산을 재발경하고, 풍경에 내재된 본질적인 자연?문화적 가치를 포착하고, 그리고 환경적으로 건강한 개발을 하면서도 다음 세대를 위해 그것들을 보존할 완전한 자원망이다. 환경교육은 '고객으로서의 장소'의 모델과 연계된 환경 교육은 DMZ의 미래를 위한 일치된 의견을 이뤄내는 관문이 될 것이다.

본 논문에서는 사회적 구성주의(social constructivism) 관점에서 고등학교 수준에서의 수학적 모델링 (mathematical modelling) 자료를 개발, 적용, 활용함으로써 학교수학과 실생활 문제를 관련시켜 학생 스스로 관찰 ${\cdot}$ 해석 ${\cdot}$ 사고 ${\cdot}$ 분석하여 구조화하는 고차원적인 인지능력의 형성과 문제 해결력을 배양할 수 있는 학습방법을 고찰한다.

Taylor series has a complicated structure comprising of various concepts in college major mathematics. This subject is a strong tool which has usefulness and applications not only in calculus, analysis, and complex analysis but also in physics, engineering etc., and other study. However, students have difficulties in understanding mathematical structure of Taylor series convergence correctly. In this study, after classifying students' mathematical characteristic into three categories, we use structural image of Taylor series convergence which associated with mathematical structure and operation acted on that structure. Thus, we try to analyze the understanding of Taylor series convergence and present the results of this study.

The texts in the national science curriculum documents are expected to be interpreted in the same meaning as that of the authors. In this study, the science achievement standards in national curriculum documents were examined through an analysis of the differences between the interpretations of Korean language education experts and science education experts. Three Korean language education experts designed and utilized an analysis framework on science curriculum standards from their viewpoints while three science education experts utilized TIMSS cognitive domain framework to analyze the 2009 Korean revised science curriculum achievement standards. The differences between interpretations of both groups were analyzed qualitatively through interviews. First of all, the two groups seemed to have different meanings for terms such as "explain," "analyze," "define," and "cause and effect." The science achievement standards described by general verbs like "explain" were interpreted in various ways. The verb "explain" that appears many times in the science achievement standards seem to be representing the "describe" subsections in the framework of Korean language education expert rather than the "explain" subsections of the framework of science education experts. Science education experts seemed to focus on prepositional phrases, which indicate inquiry process, while Korean language education experts seemed to focus on objective phrases. Moreover, the science education experts would interpret the achievement standards based on their background knowledge while the Korean language education experts would interpret them based on the structure of the sentences. This study suggests that achievement standards should specifically indicate the levels and scopes of cognitive domain as well as the knowledge domain. Also, integrations of achievement standards in cognitive domains of Korean language and science subjects should be considered.

기하는 수학의 기초를 이루는 중요한 영역이다. 그러나 기하교육을 위한 프로그램 설계와 교수전략에 대한 연구가 부족한 실정이다. 그러므로 현장의 수학교사들에 의한 프로그램개발과 동시에 프로그램과 지도방법을 통합하는 수학교사들의 지속적인 연구가 절실히 요구된다. 이에 본 연구는 영재의 특성들을 고려하고 교사 중심의 강의식 수업보다는 토론, 발표, 세미나에 적합한 프로그램을 구안해 보았다. 프로그램 설계의 내용적 면에서는 기하학의 한 방법인 해석기하학과 현재 고등학교에서 다루는 Euclid 초등기하의 한계를 넘어 공선(共線), 공점(共點)의 비계량적 개념의 사영기하학을 도입하였다. 그리고 프로그램을 운영하는 방법적인 면에서는 문제제시단계, 문제해결단계, 수학적 개념추출단계, 수학화 단계, 확장단계의 단계별 절차를 두었다. 이와 같은 수학영재교육 프로그램의 설계 및 교수전략의 목적은 수학영재들을 새로운 문제와 지식을 제안하고 생산하는 수학 창조자를 만들고자 하는데 있다.

Historically the value of the secondary Home Economics subject matter has been justified with the extrinsic aim to satisfy the needs of the individual and family and of the society. The purpose of this study is to investigate the educational and philosophical significance of the knowledge in Home Economics education through reasoning out its intrinsic aim. From the point of discipline-based curriculum, Home Economics as 'the structure of knowledge' constitutes the curriculum of the secondary Home Economics subject matter and contributes to understanding the family life intellectually with its unique perspective. When students understand these theoretical contents, they will internalize the core idea of Home Economics so that their cognitive perspective on family life is developed or widened. With this cognitive perspective, they are able to discover the aspect of family life from their daily life, to interpret and judge every situation properly. It is the presupposition of socially expected practical problem solving that makes Home Economics education intrinsically meaningful. In conclusion, the secondary Home Economics curriculum needs to be reinterpreted or reorganized as the structure of knowledge, not as fragmentary informations or facts, through which the broad cognitive perspective on family life is developed and Home Economist's mode of thinking is transmitted.

This study investigated the Aristotle's continuity and the historical development of continuity of function to explore the differences between the concepts of mathematics and students' thinking about continuity of functions. Aristotle, who sought the essence of continuity, characterized continuity as an 'indivisible unit as a whole.' Before the nineteenth century, mathematicians considered the continuity of functions based on space, and after the arithmetization of nineteenth century modern ${\epsilon}-{\delta}$ definition appeared. Some scholars thought the process was revolutionary. Students tended to think of the continuity of functions similar to that of Aristotle and mathematicians before the arithmetization, and it is inappropriate to regard students' conceptions simply as errors. This study on the continuity of functions examined that some conceptions which have been perceived as misconceptions of students could be viewed as paradigmatic thoughts rather than as errors.

The purpose of this thesis is to explain the difference between Heidegger's hermeneutical philosophy and Gadamer's philosophical hermeneutics. The difference is to say that Heidegger's philosophy begins with Aristotle's theory of category and transcendental philosophy. On the other hand, the beginning of Gadamer's philosophical research is Plato's dialog, philosophy and Hegels dialectic. 2. Heidegger regards humanism as a variant of the modern ideal of human beings. On the contrary, Gadamer understands humanism as a place where romantism leads to the ideals of human education. 3. Heidegger says that the hermeneutical circle is still a logical and existential structure of the circle. On the contrary, Gadamer understands the circle as a circle between the whole and the part. This circle is the law of traditional hermeneutics derived from the tradition of rhetoric. 4. Heidegger says Plato's philosophy is the first beginning of the substance metaphysic, Hegel's philosophy the end of the subject metaphysic. On the contrary, Gadamer says the hermeneutical understanding and the hermeneutical interpretation is endless. 5. Heidegger's ontology is as Sein zum Tode a future oriented and eschatological. On the contrary, Gadamer's hermeneutic is as Sein zum Text always the way to a past, the infinite openness.

본 연구에서는 수학성취도에서의 불평등도를 모색하였다. 구체적으로 경제적인 불평등도로서 널리 사용하는 지니계수를 활용하여 학업성취에서의 불평등도를 계산하였고, 불평등성에 대한 언어적 해석의 기준을 마련하였다. 자료 분석 결과는 농촌지역보다는 중소도시, 중소도시보다는 대도시, 대도시의 일반고 보다는 과학 고등학교에서의 불평등도가 약하게 나타났다.
