소다석회유리의 성분인 SiO₂, Na₂O, CaO가 isokom 온도에 미치는 영향을 Lakatos 모델을 이용하여 분석하였다. CaO의 양이 일정하고, SiO₂가 1 mol% 줄고 대신 Na₂O가 1 mol% 증가할 때, log η = 12.3에서는 6℃, log η = 10에서는 7℃, log η = 6.6에서는 10℃, log η = 1에서는 24℃ isokom 온도가 낮아졌다. 그리고, Na₂O의 양이 일정하고, SiO₂가 1 mol% 줄고 대신 CaO가 1 mol% 증가할 때, log η = 12.3에서는 3~4℃, log η = 10에서는 2℃ isokom 온도가 높아지고, 반대로 log η = 6.6에서는 1℃, log η = 1에서는 21℃ isokom 온도가 낮아지는 것을 알았다.

In this study, the images of science education illustrated in the books written by six major modern philosophers of science (K. R. Popper, N. R. Hanson, T. S. Kuhn, I. Lakatos, P. Feyerabend and J. Ziman) were investigated. In this article, the parts, from the books investigated, which have direct relevance to science education are quoted and the discussions by the researchers on them are added. Particularly, the learning by trial and error (of Popper), the role of context in scientific thinking (of Hanson), science education through the history of science (of Lakatos), science education appreciating individualities and voluntary curiosity (of Feyerabend) and the social aspect of science as a source of its rationality (of Ziman) appear to be the main points which have direct relevances and meaningful implications to science education but which have not been considered or discussed in detail in science education.

Background : The current medical statistics used in clinical research are the results of Fisher's significance test and the Neyman-Pearson hypothesis test, which were combined by psychologists. Also, in the philosophical background, it is related to Popper's falsificationism based hypothesis-deductive method and reduction to absurdity. Objectives : This study was designed to find complementary and alternative methods of null hypothesis and alternative hypothesis used for the clinical research methodology of Korean medicine otolaryngology. Methods : The body of this paper was divided into seven part. These are historical background, hypothesis test, hypothesis test method used in the design of clinical study, falsificationism and reduction to absurdity, problem and alternative method of the Neyman-Pearson hypothesis test, diagnosis example of sinusitis differentiation syndromes by Bayesian statistics. Through this process, we found out problems of frequentist statistics and suggested alternative methods. Result & Conclusion : As a solution to the problems of the null hypothesis and the alternative hypothesis, there are effects size, confidence interval, Bayesian statistics and Lakatos methodology of scientific research programmes.

This study analyzes the epistemological meaning of‘social construction’in mathematical instruction. The perspective that consider the cognition of mathematical concept as a social construction is explained by a cyclic scheme of an academic context and a school context. Both of the contexts require a public procedure, social conversation. However, there is a considerable difference that in the academic context it is Lakatos' ‘logic of mathematical discovery’In the school context, it is Vygotsky's‘instructional and learning interaction’. In the situation of mathematics education, the‘society’which has an influence on learner's cognition does not only mean‘collective members’, but‘form of life’which is constituted by the activity with purposes, language, discourse, etc. Teachers have to play a central role that guide and coordinate the educational process involving interactions with learners in this context. We can get useful suggestions to mathematics education through this consideration of the social contexts and levels to form didactical situations of mathematics.

Dialectical Methods is the form in which thinking and being developed, according to Hegel. Every given definition removes itself necessarily and goes over to its contrary definition. The mutual struggle brings us to a new definition, which is richer and more concrete insofar as it embraces the original definition, but on a higher level. The purpose of this study is to enhancing student's creative thinking in mathematics by dialectical methods. The conclusions drawn from the results obtained in this study are as follows, First the introduction of dialectical methods to mathematics education had been made by Lakatos, Brousseau, Freudenthal. Second, the dialectical teaching methods in mathematics are developed from dialectical methods: the step of affirmation - the step of negation - the step of sublation. Third, the students who team mathematics by dialectical teaching methods are creative in its implications.

It has been proposed since modern times that we need to consult the history of mathematics in teaching mathematics, and some modifications of this principle were made recently by Lakatos, Freudenthal, and Brousseau. It may be necessary to have a direction which we consult when modifying the history of mathematics for students. In this article, we analyse the elements of the cognitive interest in Hamilton's discovery of the quaternions and in the history of discovery of imaginary numbers, and we investigate the effects of these elements on attention of the students of nowadays. These works may give a direction to the historic-genetic principle in teaching mathematics.

이 연구에서는 카발리에리가 제시한 두 가지 불가분량법 사이의 전환에 대해 고찰한다. 불가분량법 사용에 대한 반대에 대응하기 위해, 카발리에리는 그가 처음 제시했던 불가분량법을 수정하였다. 이 과정에 대한 분석을 통해, 이 연구에서는 카발리에리가 불가분량과 관련된 패러독스를 피하기 위해 도형의 밀도를 반영하는 방향으로 불가분량법을 바꾸었다는 면과 함께, 라카토스의 이론에 근거해, 이러한 전환이 불완전한 보조정리 합체법으로서의 특정을 지니고 있음을 밝힌다.

This study analyses on the history of uniform convergence, and discusses its educational implications. First, this study inspects 'overflowing of the Euclidean methodology' which was suggested by Lakatos as a cause of tardy appearance of uniform convergence, and reinterprets that cause in the perspective of 'symbolization'. Second, this study looks into the emergence of uniform convergence of Seidel and Weierstrass in this viewpoint of symbolization. As a result, of analysis, we come to know that the definition of uniform convergence had been changed into the theory of 'domain and graph' from that of 'point and function value' by the location change of the quantifier. As these results, this study puts forward an educational suggestion from an angle of epistemological obstacle, concept definition and concept image.

본 연구는 개별화된 경쟁에 치우쳐 있는 우리나라 수학교육 환경에서 고등학교 영재학생들에게 수학 발전의 사회적 과정을 경험할 수 있는 기회를 제공하기 위하여 온라인 탐구 커뮤니티의 건설을 시도하였다. 2012년 B과학고등학교에서 개설된 두 개의 미적분학 II 강좌를 수강하였던 14명의 학생들이 지정된 위키 사이트에 접속하여 약 70일간 10개의 문제를 풀었다. 협력 문제해결 과정에서 위키는 학생들의 흩어져 있는 사고과정을 공유되는 세계 내에 효과적으로 매개함으로써 상호학습이 이루어지는 것을 가능하게 하였다. 또한 학생들의 협력 문제해결의 패턴은 Lakatos(1976)의 '증명과 반박'과 비슷하게 '풀이와 반박'으로 특징지어졌으며 학생들은 이 과정을 통해 학교수학적 지식의 성장을 경험할 수 있었다. 실험 종료 후 실시된 인터뷰와 설문조사에서 담당교사와 학생들은 협력 문제해결 도구로서의 위키에 대해 매우 긍정적인 반응을 보였다. 따라서 본 연구에서 고등학교 영재학생들에게 위키는 수학적 지식의 사회적 측면에 대한 학습기회를 제공할 수 있는 가치 있는 수학교육 도구라고 평가된다.
