본 연구는 고등학교 학생들의 수학의 본질에 대한 인식과 신념 및 수학 학습에 대한 신념을 살펴보고, 수학교육의 발전을 위한 시사점을 찾아보는 데 목적이 있다. 이를 위해 일반계고 학생들과 전문계고 학생들의 수학의 본질에 대한 인식과 신념, 수학 학습에 대한 신념을 비교 분석하였고 각 학교의 학생들에 대한 신념의 차이점을 살펴보았다. 그 결과, 일반계고와 전문계고의 학교 유형별로 수학의 본질에 대한 인식과 신념, 수학 학습에 대한 신념의 차이가 두드러지게 나타났다. 또 고등학교 학생들은 수학의 가치성에 대해 낮게 평가하였으며, 일반계고 학생들이 전문계고 학생들보다 수학의 '심미적 가치', '도야적 가치' 및 '실용적 가치'를 더 낮게 평가하고 있는 것으로 분석되었다.

As intuition is more unreliable than logic or reason, its studies in mathematics and mathematics education have not been done that much. But it has played an important role in the invention and development of mathematics with logic. So, it is necessary to recognize and explore the value of intuition in mathematics education. In this paper, I investigate the function and role of intuition in terms of mathematical learning and problem solving. Especially, I discuss the positive and negative aspects of intuition with its characters. The intuitive acceptance is decided by self-evidence and confidence. In relation to the intuitive acceptance, it is discussed about the pedagogical problems and the role of intuitive thinking in terms of creative problem solving perspectives. Intuition is recognized as an innate ability that all people have. So, we have to concentrate on the mathematics education via intuition and the complementary between intuition and logic. For further research, I suggest the studies for the mathematics education via intuition for students' mathematical development.

In this study, a class of nonlinear boundary fractional Caputo Volterra-Fredholm integro-differential equations (CV-FIDEs) is taken into account. Under specific assumptions about the available data, we firstly demonstrate the existence and uniqueness features of the solution. The Gronwall's inequality, a adequate singular Hölder's inequality, and the fixed point theorem using an a priori estimate procedure. Finally, a case study is provided to highlight the findings.

According to changing the society rapidly in the 21s1 century, the self-regulated learning ability is considered as an ability of which people should carry on their lives. The purpose of this study was to investigate prospective elementary school teachers in mathematics teaching method class in terms of the following areas: (1) the degree of their abilities shown the lower level factors of motivated strategies for learning such as self-efficacy, intrinsic value, anxiety, cognitive strategy use, and self-regulation (2) relations between factors of motivated strategies for loaming and performance of prospective elementary school teachers The results show that the prospective elementary school teachers showed above the mean value of the motivated strategies for learning and there are positive relations among lower level factors of motivated strategies fur learning except anxiety, positive relation between motivated strategies for learning and achievement. In order to help the prospective elementary school teacher to improve their motivated strategies fur learning in their elementary mathematics teaching method lecture, several methods such as mathematical connections to real world problem, history of mathematics and interview with mathematicians and application of feller's ARCS model to elementary mathematics education are suggested.

본 연구는 교사와 학생의 가치의 변화 양상을 분석하기 위해 수학학습 가치 설문지를 활용하여 15차시 수업이 진행되는 과정에서 학생들과 교사의 가치를 4차에 걸쳐 분석하였다. 그 결과 가치는 개인이 수많은 경험을 거쳐 내면화된 깊이 있는 판단 양식임에도 불구하고 수업이 진행됨에 따라 많은 변화가 나타났다. 교사는 자신이 중요하게 생각하는 가치를 무조건 강요하기 보다는 학생들이 무엇을 중요하게 생각하는지를 반영하여 자신의 목표를 수정해 나갔다. 수학적 가치의 경우, 합리주의, 객관주의, 미스터리는 교사와 학생이 서로 수렴하였고, 통제는 일관되게 유지되었으며, 개방의 경우 교사와 학생모두 상향 하였다. 수학 교육적 가치의 경우에는 이해, 즐거움, 용어, 적용의 경우 서로 수렴하였고, 성취는 일관되게 유지되었다. 또한 교사는 효과적인 수업으로 나아가기 위해 끊임없이 학생과의 가치에 대해 협상해 가면서 몇 가지 전략을 사용했다. 이러한 연구 결과를 바탕으로 진정한 의미에서 학습자 중심수업으로 나아가기 위한 한 가지 방안으로 가치가 중요한 요인이 될 수 있다는 시사점을 제공하고자 하였다.

Although many people have recognized the importance of history of mathematics in mathematics education, there are few studies that history and mathematics educations are connected. In this paper, we present and discuss the ways of introducing the instruction with mathematics machines. This instruction use the history of mathematics as part of a class not as a tool to stimulate students' interest but as a goal that it can be targeted mathematical itself. To do this, we first analyze the characteristics of applying history of mathematics in mathematical education, second, describe the meaning and the educational value of mathematical machines, and finally explained the way of applying history of mathematics with mathematics machines. The Instruction of history of mathematics with mathematics machines has advantages that practice (manipulation and experiment) and theory (elaboration of definition, production of conjectures and constructions of proofs) are interlaced within a historic-cultural perspective.

In this paper, we will first prove the linearity of additive mappings with bounded value near a point. And by using our theorem we will investigate the instability of the Cauchy equation in ℝ².

This paper deals with existence of positive solutions of nonlinear elliptic singular boundary value problems in a ball. It is shown that results of Grandall et al. [1] and [2] follow as special cases of our results proved in this article.

We consider the boundary value problem with a Dirichlet condition for a second order linear uniformly elliptic operator in a non-divergence form. We study some properties of a barrier at infinity which was introduced by Meyers and Serrin to investigate a solution in an exterior domains. Also, we construct a modified barrier for more general domain than an exterior domain.
