Herbart's education provides an implication for mathematics education that combine a practical ethics education with mathematics education. Herbart show that an theoretical mathematics education would not exist as a sole. It implies that mathematics education must do activities that take into consideration the humanity in its entirety. The theory of mathematics education based on Herbart's ethics theory of education reveals the entireness of human. There are possible explanations for the ways to increase the value of the mathematics education as an education for whole human. It is that the advantage of learning mathematics is not only that we can solve the problems we face in our lives but also that we can acquire a form of life.

본 연구는 미래 세대를 위한 교육 방법의 방향성을 제안하는 것이다. 이와 같은 방향성을 제안하기 위해 코딩활동과 수학적 모델링을 통합한 교수학습자료를 하향식과 상향식 과정을 통해 개발하였다. 코딩과 공학 전문가와 수학교육 전문가들이 협의회를 통해 교수·학습 자료를 개발하고(하향식 과정) 고등학교 1학년 학생 24명에게 적용하여 학생의 반응을 토대로 자료를 수정하였다(상향식 과정). 그 결과, 수업에 참여한 학생들은 개발된 자료를 바탕으로 동료들과 논의를 하고 코드를 수정하여 자신만의 스토리를 시각적으로 구현하였다. 한편 이 과정을 통해 수학 학습에 대한 흥미와 동기가 유발될 수 있고, 더 나아가 수학의 개념 이해, 문제 제기, 문제 해결에도 도움을 줄 수 있다고 결론지을 수 있었다. 이러한 결과를 토대로 4차 산업혁명 시대에 필요한 수학적 모델링과 코딩 활동을 통합하는 교육과정을 개발하는데 아이디어를 제공하였다고 볼 수 있다.

무선 인터넷 시대를 맞아 기기의 사용은 PC나 노트북 컴퓨터를 벗어나 휴대폰으로 확장되고 있다. 본 연구는 테크놀로지를 학습현장에 활용하는 방안의 일환으로 휴대폰을 기반으로 한 M-learning의 학습효과를 파악하고자 설계되었다. 그 동안 전통적인 학습환경이 면대면 학습위주였다면 이런 인터넷환경은 유비쿼터스적인 환경을 제공하므로 학습의 기회를 좀 더 많은 사람에게 저렴한 비용으로 제공할 수 있는 장점이 있다. 학생들의 폰강의 대한 인식은 유비쿼터스 환경, 요점정리, 저렴한 비용 등의 긍정적인 측면을 선호하였고 시간이 지남에 따라 폰강 학습을 통해 수학에 대한 성향이 향상되었으며 보충수업 반보다 성취도에서 유의미한 향상을 나타냈다.

This study will contribute to improve intimacy and interests of students in mathematics and to cultivate their abilities and attitudes to continuously learn through problem posing activities using fairy tales. An experimental study was carried out two classes of the fifth grade (total 60 of students, each group 30 os students) in G elementary school located in Daegu Metropolitan City. This experiment was performed for thirteen weeks. For this study, using two examination devices for measuring mathematical attitude and learning achievement, pre- and post-tests were carried out. As a result, it was found that two groups are identical groups. Problem posing activities with fairy tales had significant effect on mathematical attitudes of children and learning achievement of children.

The constructivism is an important stream of the recent trends of mathematics education. In order for students to construct their knowledge for themselves, above all, it should be a prerequisite that they participate in actively, Using games helps students to participate in learning mathematics actively. I think, up to now, mathematics teachers use games mainly for motivation and it does not connect to true learning mathematics through using games. So, the purposes of this study are developing the mathematical games connecting to mathematical contents closely, designing the teaching models to connect game activities to learning mathematics, and developing several teaching plans using games to mathematics class. In this study, I propose what conditions 'good' game should have, classify games as practice game, concept learning game, and strategy game, and develop 43 games from 1 to 6 grade. And I design the teaching models depending on the game types and develop the teaching plans.

Since textbooks for elementary school mathematics in accordance with the seventh curriculum are 'Class I' textbooks, which are used as one and only one textbooks throughout the country, the following aspects have been considered： In the legal aspect, the contents including the curriculum for mathematics asked of the Writing Committee by the Ministry of Education were reflected; in the aspect of theory of mathematics education, the textbooks are written in a way appropriate to theory of mathematics education; and in the aspect of application of reality, the textbooks are written to help improving mathematics education in classrooms. Therefore, the main frame of writing the textbooks is to make students feel proud enough to say "I have done mathematics", through helping students rationally solve problems surrounding them by themselves with their experiences and activities. In the above viewpoint the following sentence is reflected upon: "Hundred explanations are not equal to one manipulation activity."

The present study extends previous research in this area by investigating perceptions of change and reactions to reform efforts by pre-service and practicing secondary school mathematics teachers in the People's Republic of China (PRC) and the United States of America. Interviews were used to gather data about school experiences, teaching practices, and planned changes in mathematics programs. Analysis of the interview data supported earlier findings with respect to the well-planned nature of lessons by PRC teachers and the influence of mathematics contents and examination systems in the PRC. Findings also indicated a general agreement among teachers from both countries favoring less lecturing and more discussion and interactive activities. There were contrasts by nationality in descriptions of future teaching, ideal lessons, sources of teaching ideas, and preferences about school mathematics programs.

This paper analyzed <7-나> and <8-나> textbooks and teacher instruction activities in classrooms, focusing on procedures used to solve construction problems. The analysis of the teachers' instruction and organization of the construction unit in <7-나> textbooks showed that the majority of the textbooks focused on the second step, i.e., the constructive step. Of the four steps for solving construction problems, teachers placed the most emphasis on the constructive order. The result of the analysis of <8-나> textbooks showed that a large number of textbooks explained the meaning of theorems that were to be proved, and that teachers demonstrated new terms by using a paper-folding activities, but there were no textbooks that tried to prove theorems through the process of construction. Here are two alternative suggestions for teaching strategies related to the construction step, a crucial means of connecting intuitive geometry with formal geometry. First, it is necessary to teach the four steps for solving construction problems in a practical manner and to divide instruction time evenly among the <7-나> textbooks' construction units. The four steps are analysis, construction, verification, and reflection. Second, it is necessary to understand the nature of geometrical figures involved before proving the problems and introducing the construction part as a tool for conjecture upon theorems used in <8-나> textbooks' demonstrative geometry units.

본 연구는 초등 수학 교과서의 과제를 내용 기반 개방형 과제로 변형함으로써, 탐구를 위한 탱그램의 활용 가능성을 탐색하였다. 선행연구를 분석한 결과, 수학 과제 변형의 교육적 효과와 탱그램 활동의 교육적 가치를 확인하였으며, 교과서 분석을 통해 교과서에 제시된 탱그램 활동은 놀이 수준에 그칠 가능성이 있음을 확인하였다. 이에, 2015 개정 교육과정에 따른 교과서 탱그램 과제의 변형을 시도하였다. 연구 결과, 폐쇄형 과제를 개방형 과제로 변형을 시도해 본다면 교사의 전문성 향상과 학생들의 다양한 반응 등을 기대할 수 있었다.

초등학교 수학 교과서에 제시된 도형의 높이 개념과 측정 활동은 관련 도형의 넓이와 부피를 구하는데 필수적이다. 교과서에서 평면 도형의 높이에서 삼각형은 밑변과 마주보는 꼭짓점에서 밑변에 수직으로 그은 선분, 평행사변형과 사다리꼴은 두 밑변 사이의 거리로 서술되었다. 또한 입체 도형의 높이에서 각기둥은 두 밑면 사이의 거리, 각뿔은 꼭짓점에서 밑면에 수직인 선분, 원뿔은 꼭짓점에서 밑면에 수직인 선분의 길이, 원기둥은 두 밑면에 수직인 선분의 길이로 서술되었다. 본 논문에서는 이러한 높이 개념과 측정 활동에서 나타나는 문제점을 분석하여 방안을 제시하고, 이를 바탕으로 수학 교수 학습에서의 시사점을 도출하였다.
