This study examined what questions posed, and for arranging the matters, what decisions made, what practices put into by elementary preservice teachers during his or her enacting and reflecting mathematics teaching. Analysis of the study focused on the mathematics instructions practiced by four participants in practicum for senior students. Their own questions raised by each one in the instructional designs, performances, and reflections were picked out and categorized by five dimensions of mathematics instruction; the nature of classroom tasks, the role of the teacher, the social culture of the classroom, mathematical tools as learning supports, and equity and accessibility. Their instructional decision-makings and action-takings for answering to these questions were analised.

In this paper, we report the types of teaching moves a mathematics teacher educator attempted in his teaching of third-grade students at an urban elementary school in South Korea over two months. We analyze the lesson videos to find the patterns of teaching moves and speculate the link between the teaching and students' mathematical proficiencies recommended in the Common Core State Standards for Mathematical Practices. Closely related teaching moves to the students' development of a certain mathematical proficiency would imply the exemplary practices that teachers-both inservice and preservice teachers-can implement in their classrooms.

Competent mathematics teachers need to implement the responsive teaching strategy to use student thinking to make instructional decisions. However, the responsive teaching strategy is difficult to implement, and limited research has been conducted in traditional classroom settings. Therefore, we need a better understanding of responsive teaching practices to support mathematics teachers adopting and implementing them in their classrooms. Responsive teaching strategy is connected with teachers' noticing practice because mathematics teachers' ability to notice classroom events and student thinking is connected with their interaction with students. In this regard, this review introduced and examined a study of the relationship between mathematics teachers' noticing and responsive teaching: In the context of teaching for all students' mathematical thinking conducted by Kim et al. (2017).

In order to provide pre-service teachers with rich contexts for learning to teach mathematics, teacher education programs usually combine a mathematics methods course with clinical teaching experiences. This paper explores a student-teacher's experience of loaming to teach mathematics by observing one mathematics methods course she was enrolled in and her actual classroom teaching. In particular, this ethnographic case study examines how the student-teacher understands and applies messages from the methods course to her teaching practices. Some differences emerge with regard to ideas and practices. The underlying factors for explaining the gaps are discussed. Finally, this paper provides some implications for pre-service teacher education.

2015년 1학기와 2학기에 J 교육대학에서 실시한 교육실습 1과 교육실습 2에 모두 참여한 11명의 초등 예비교사들을 대상으로 수학 수업전문성 지식들로 구성된 반성적 수학 수업 분석지를 활용하여 수업 반성을 하게 한 후, 수학 수업 횟수에 따른 초등 예비교사들의 수학 수업전문성 지식의 활용 양상을 연구하였다. 그 결과는 다음과 같다. 첫째, 수학 수업 실습의 횟수가 증가함에 따라 실습에 참여한 예비교사들의 수학 수업전문성 지식 활용이 증가하였고, 7명의 수학 수업전문성 지식 활용도는 크게 증가하였다. 그러나 수학 수업전문성 지식 활용이 증가한 하위영역의 개수는 최소 2개에서 최대 7개까지 예비교사에 따라 달랐다. 둘째, 수학 수업 실습을 2회나 3회 실시한 예비교사들보다 4회 실시한 예비교사들의 수학 수업전문성 지식의 활용도가 더 높았다. 셋째, 2회나 3회 수업한 일부 예비교사들은 수학 수업전문성 지식의 활용도가 증가한 하위영역에서 조차도 수업 실습 전체 과정 동안 단 한 번도 해당 하위영역 만점의 90%에 도달하지 못하였다. 넷째, 수학 수업에서 실습에 참여한 예비교사들이 가장 어려움을 느낀 하위영역은 '수업 전 반성 - 교수관점 - 수학교과 지식의 이해'로 분석되었으며, 그 이유로는 대부분의 예비교사들이 수학적 개념의 역사적 배경에 관한 자료 부족을 호소했다.

본 연구는 수학교수에서 중요도가 높은 관행들(High-leverage Teaching Practices [HLPs])에 대해 예비교사들이 스스로 자각하고 있는 준비도를 조사하였다. 미국 중서부에 위치한 대학에서 수학교육방법론을 수강하고 있는 81명의 예비초등교사들이 HLPs에 대한 자신감 및 능력에 대한 자가응답을 요하는 설문조사에 참여하였다. 특히 이 연구는 예비교사들이 자각하고 있는 HLPs에 대한 준비도와 수학교사교육자들이 예측하고 있는 교사교육 진행과정에 대한 비교 연구를 하였다. 연구결과는 예비교사들과 수학교사교육자들이 HLPs의 복잡성에 대해 상당히 다른 견해를 보이고 있음을 제시하고 있다. 본 연구는 교사교육 프로그램들이 각각의 수학교수관행을 세분화하여 고찰할 수 있는 구체적인 기회를 예비교사들에게 제공할 것을 제안한다.

Variable concept plays a crucial role in understanding not only algebra itself but also school mathematics which is algebra-oriented. It solves as an essential means in applying mathematics to the real world because il enables us to describe varying phenomena in the real world. In this study, we examined some matters related to the learning of variable concept in school mathematics. In Particular, we discussed on the teaching of variable concept in the [7-first] stage of the 7th Mathematics Curriculum. We analysed the textbooks in the [7-first] stage and attempted to explain concretely the contents and teaching methods of variable concept which be taught in school mathematics. After reconsidering the practices on variable concept teaching, we pointed out the problems of formalistic teaching method and then proposed the direction in which variable concept teaching should go.

본 연구에서는 초등학교 교사들을 대상으로 2007 개정 교육과정 3, 4학년 수학 교과서의 '열린 질문'에 대한 인식과 지도 실태를 설문조사 하였다. 그 결과, 교사들은 열린 질문의 취지에 대해서는 전반적으로 공감하고 있지만 교과서에 제시된 열린 질문과 그 지도상의 실제에 대해서는 교과서 열린 질문 자체, 교실 수업에서의 실행, 교사용 지도서와 교사연수 등에 걸쳐 여러 문제점을 인식하고 있다는 사실이 확인되었다. 본 연구에서는 이러한 조사 결과를 바탕으로 교과서 '열린 질문'의 개선 방향을 제안하였다.

The purpose of this study was to examine what factors affect the construction of preservice white mathematics teachers' racial identities and the relationship between their racial identities and Culturally Relevant Teaching (CRT) practices. We examined five white female preservice teachers who enrolled in an elementary mathematics methods course at a private university in the US. We collected data consisting of lesson plans, semi-structured interviews, and reflection of a taught lesson in the 2018 fall term and examined them using qualitative research methods. We found that preservice teachers' racial identities were affected by their backgrounds, K-12 school experiences, and practicum school environment. We also found a relationship between teachers' sensitivity to racial issues and their endorsement of CRT strategies. The findings also revealed that the relationships were mediated by practicum school contexts. Based on the findings, we provided practical implications for the teacher education programs.

In this paper, we articulate what is a lesson for all learners with different cognitive levels and what kind of teaching practices are required to implement this type of lesson. For all learners' own sense-making, open-ended tasks are the primary sources to bring their various mathematical ideas. These tasks can be meaningfully implemented by appropriate teaching practices: providing enough time (for thinking deeply and for preparing a reply), acting intentionally (alternative wrapping up activities and appointment of a struggling student), and cultivating collaborative classroom norms (respecting peer's thinking and learning from peers). This exploratory study has the potential to help practitioners and researchers understand the complexity of the work of teaching and clarify how to deal with such complexity.
