Current interest in mathematics learning that focuses on understanding, mathematical reasoning and meaning making underscores the need to develop ways of analyzing classrooms that foster these types of learning. In this paper, I show that the constructs of social and sociomathematical norms, which grew out of taking a symbolic interactionist perspective, and Toulmins scheme for argumentation as elaborated for mathematics education by Krummheuer, provide us with means to analyze aspects of explanation justification and argumentation in mathematics classrooms, including means through which they can be fostered. Examples from a variety of classrooms are used to clarify how these notions can inform instruction at all levels, from the elementary grades through university-level mathematics.

The six core competencies included in the mathematics curriculum revised in 2015 are problem solving, reasoning, communication, attitude and practice, creativity and convergence, information processing. In particular, the problem solving is very important for students' enhancing much higher mathematical thinking. Based on this competency, this study selected the four elements of the problem solving such as problem solving process, cooperative problem solving, mathematical modeling, problem posing. And also this study selected the domain of function which is comprised of the content of the coordinate plane, the graph, proportionality in the seventh grade mathematics textbook. By the subject of the ten kinds of textbook, this study examined how the four elements of the problem solving competency were shown in each textbook.

This study analyzes the tasks selected and implemented by pre-service mathematics teachers to support students' development of epistemic actions. Data was collected from 20 students who participated in a mathematics education curriculum theory course during one semester, and multiple data sources were used to gather information about the microteaching sessions. The study focused on the tasks selected and demonstrated during microteaching by pre-service teachers. The results suggest that providing students with a variety of learning opportunities that engage them in different combinations of abductive and deductive epistemic actions is important. The tasks selected by pre-service teachers primarily focused on understanding concepts, calculation, and reasoning. However, the use of engineering tools may present challenges as it requires students to engage in two epistemic actions simultaneously. The study's findings can inform the development of more effective approaches to mathematics education and can guide the development of teacher training programs.

The purpose of this study is to analyze the influences of discussion-based learning of mathematics using smart phone application on the middle school students' mathematics learning. For this purpose, we selected 6 open problems suitable for learning mathematical reasoning and five 3rd grade middle school students as participants who expected to participate in 6 lessons of discussion-based learning of mathematics using smart phone application. From the analysis of 6 lessons, we found the following results. First, attending the lessons of discussion-based learning of mathematics using smart phone application makes students more interested in mathematics and change their mathematics learning attitudes more positively. Second, the lessons of discussion-based learning of mathematics using smart phone application facilitate students' mathematical communication with the help of various communication methods using many functions of smart phone applications. Third, the lessons of discussion-based learning of mathematics using smart phone application provide teachers with teaching-learning environment where teachers can easily give their students consultation about mathematics learning or daily life.

2015 개정 수학과 교육과정에서 문제해결능력 함양을 위한 교수 학습 방법으로 수학적 모델링이 제시되면서, 국내에서 1990년 이래로 꾸준하게 연구되어 온 수학적 모델링에 관한 논의가 더욱 활발해지고 있다. 이에 본 연구는 수학적 모델링의 교육적 가치와 현장 적용의 필요성을 재음미해보고자, 수학 교과 역량의 관점에서 수학적 모델링에 관한 선행 연구를 고찰하였다. 그 결과, 수학적 모델링은 수학 교과 역량 중 문제해결의 하위 요소로 제시되고는 있지만, 문제해결 뿐만 아니라 추론, 의사소통, 창의 융합, 정보 처리, 태도 및 실천을 지지하는 교수 학습 방법임을 확인할 수 있었다. 이러한 측면에서, 수학 교과 역량에서의 수학적 모델링의 위치에 대한 논의의 필요성과 학교 현장 적용을 위한 방안으로 수학적 모델링에 대한 교사 교육 및 수학 교과서와 수업에서 수학적 모델링 과제의 적극적인 활용을 제안하였다.

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.

본 연구는 비와 비율에 대한 한국과 싱가포르의 관점을 비교·분석하고 두 나라의 교수·학습 방법이 어떻게 전개되는지를 양적 추론의 측면에서 탐색하였다. 연구 결과 교과서에 제시된 문제 상황, 단위의 유형, 단위 사용 방법, 두 양의 종류와 관계 및 표현 방법 등 전반적으로 많은 차이가 나타났다. 이를 통해 한국과 싱가포르는 비와 비율에 대한 서로 상이한 관점을 취하고 있으며, 특히 한국은 다른 선행연구와는 구분되는 독특한 관점을 취하고 있다는 것을 알 수 있었다. 이를 바탕으로 비와 비율과 관련된 교과서와 교수·학습 방법의 개선을 위한 시사점을 제안하였다.

Under 2009 Revised Mathematics Curriculum and 2015 Revised Mathematics Curriculum, mathematics teachers can help students inductively express real life problems related to sequences but have difficulties in dealing with problems asking the general terms of the sequences defined inductively due to 'Guidelines for Teaching and Learning'. Because most of textbooks mainly deal with the simple calculation for the sums of sequences, students tend to follow them rather than developing their inductive and deductive reasoning through finding patterns in the sequences. In this study, we reconstruct 8 problems to find the sums of sequences in MukSaJipSanBup which is known as one of the oldest mathematics book of Chosun Dynasty, using the terminology and symbols of the current curriculum. Such kind of problems can be given in textbooks and used for teaching and learning. Using problems in mathematical books of Chosun Dynasty with suitable modifications for teaching and learning is a good method which not only help students feel the usefulness of mathematics but also learn the cultural value of our traditional mathematics and have the pride for it.
