2015 개정 수학과 교육과정에서 교과 역량의 필요성이 부각되고 그 하위 요소까지 명시되었지만, 교육과정을 구체적으로 반영한 교과서에서 정작 교과 역량을 얼마나 어느 정도로 다루고 있는지에 대한 분석은 별반 없다. 이에 본 논문은 초등학교 3~4학년군 수학 교과서에 의도된 교과 역량을 분석하였다. 그 결과, 의사소통과 추론 능력이 전체의 절반 정도로 가장 많이 나타났고, 그 다음으로 창의·융합, 정보 처리, 태도 및 실천, 문제 해결 능력 순서로 제시되어 있었다. 또한 각 교과 역량의 하위 요소별로 분석한 결과 그 편차가 큰 것을 알 수 있었다. 본 논문은 수학 교과 역량별로 하위 요소까지 분석하고 구체적인 사례를 제시함으로써 수학 교과서에 의도된 교과 역량의 특성을 파악하고 더불어 역량 기반의 교과서 개발과 관련하여 논의를 촉진할 것으로 기대된다.

Nowadays many articles describe the controlling models for four rotor flying vehicle. Basic approaches to the problem of these articles are mathematical expressions describing dynamics of the models of the vehicle and PID control for manipulating the object in 3 dimensional space. Design of control systems is usually started by careful consideration of its mathematical model description. We present a detailed mathematical model for a quad rotor. This paper first considers simulation of quadcopter control based on full state feedback technique with linearization in MATLAB environment and shows the results of the simulations. Finally will be shown experimental results of the state feedback control implemented in real model.

Nowadays application of modem achievements of information technologies in science, engineering and education is usual phenomenon. Application of these technologies allows easily creating new methods of learning of mathematics. More of new methods of creation of multimedia electronic manuals on high mathematics are founded to application of multimedia and communication opportunities of the computer. But application only multimedia and communication opportunities of the computer at creation of multimedia electronic manuals on high mathematics is insufficient to elimination of 'gap' between training and studying high mathematics. So, we offer a new way of the decision of this problem: creation of a multimedia electronic manual on high mathematics with built-in a mathematical environment MathCad in the national language.

The purpose of this review of literature is to investigate what kinds of research have been done on social construction of mathematics understanding among elementary students in small groups. Only empirical studies were reviewed, and then grouping was done in terms of the purpose of the study. This grouping identified three categories: 1) Social and mathematical norms in mathematics classroom, 2) Teaching productive communication behaviors for active learning in small group, and 3) Participation roles and communication behaviors in different group structure. To enhance social construction of mathematics understanding in small group settings two suggestions are made: the importance of the selection of collaborative tasks or problems and teachers' beliefs about mathematics and the teaching an learning of mathematics.

This study was aimed to examine problem-solving ability of fifth graders on two types of mathematical essay problems, and to analyze the process of mathematical justification in solving the essay problems. For this purpose, a total of 14 mathematical essay problems were developed, in which half of the items were single tasks and the other half were data-provided tasks. Sixteen students with higher academic achievements in mathematics and the Korean language were chosen, and were given to solve the mathematical essay problems individually. They then were asked to justify their solution methods in groups of 4 and to reach a consensus through negotiation among group members. Students were good at understanding the given single tasks but they often revealed lack of logical thinking and representation. They also tended to use everyday language rather than mathematical language in explaining their solution processes. Some students experienced difficulty in understanding the meaning of data in the essay problems. With regard to mathematical justification, students employed more internal justification by experience or mathematical logic than external justification by authority. Given this, this paper includes implications for teachers on how they need to teach mathematics in order to foster students' logical thinking and communication.

근래 수학의 학습에서 수학의 내용뿐만 아니라 수학적 과정을 평가할 수 있는 문항의 중요성에 대한 인식이 확산되고 있다. 본 연구에서는 수학의 내용과 더불어 수학적 과정 즉, 수학적 의사소통, 추론, 문제해결을 명시적인 평가요소로 포함하는 서술형 문항으로서 '수학적 과정 문항'이라는 개념을 제안하고, 수학적 과정 문항의 제작을 위한 예시 평가기준과 문항 및 채점기준 개발을 통해 서술형 문항을 활용한 수학적 과정 평가 방안을 논의한다.

One of the important aims in mathematics education is to enhance mathematical thinking for students. And students posing questions is a vital process in mathematical thinking as it is part of the reasoning and communication of their learning. This paper investigates how students develop their mathematical thinking through working on tasks in fractions and posing their own questions after successfully solved the problems. The teaching was conducted in primary five classes and the results showed that students' reasoning is related to their analogy with what previously learned. Also, posing their problems after solving the problem not only helps students to understand the structure of the problem, it also helps students to explore on different routes in solving the problem and extend their learning content.

The purposes of this study were to explore in depth about 5th graders' mathematical speaking and writing abilities and to investigate differences on those abilities. The study involved 3 5th graders and their speaking and writing abilities in geometry area were analyzed. According to the results of the study, the children had difficulties in selecting and using appropriate mathematical languages to explain mathematical concepts, mathematical ideas, and problem solving steps. The children who participated in the study showed higher ability in speaking than writing.

We study a maximal operator defined on spaces of homogeneous type, and we prove that this operator is of weak type (1,1). As a consequence we show that the maximal operator belongs to the Muckenhoupt's class $A_1$.

One of important topics in mathematics education research is communication. Mathematical communication consists of writing, reading, listening and speaking. But, research on reading has not yet to have a commensurate emphasis, despite important changes that have occurred in the theory and practice of communication. This study is intended to search for reading in school mathematics. First, we explore theories of reading and reading instruction. Second, the factors involved in reading are examined. These factors are learners, texts and teachers. Third, we provide a variety of reading strategies that are reading and enacting strategy, reconstructing strategy, presupposing strategy, becoming an author strategy, sketch to stretch strategy and reading- cooperative learning strategy. They will help students to foster students' mathematical ability as well as reading skill.
