본 연구에서는 조작적 수학활동의 관점에서 일차방정식 해결과정에 관한 이론적 분석을 시도하였다. 연구방법으로 TEP(Teaching Experiment Methodology)를 사용하였다. 이 분석은 학생들의 자연수학습과 분수학습에 관해 기존에 연구 되어왔던 이차적 모델들과 연구자 자신들의 수학적 지식을 근거로 한 일차적 분석이 조합되어 이루어 졌으며, 학생들의 Explicitly Nested number Sequence (ENS)로부터 시작하여 일차방정식을 풀기 위해 필요한 그 이상의 수학적 지식에 이르기까지 고찰되었다. 연구 결과, 같은 형태의 일차방정식이라 하더라도, 일차방정식을 구성하고 있는 계수와 상수의 종류에 따라 필요한 수학적 지식이 달라질 수 있음을 보여주고 있으며, 따라서 교수학적 시사점으로서 교사들은 요구되는 수학적 지식에 따라 다양한 일차방정식 문제들을 구분할 수 있어야 하고, 또한 구분된 문제들을 상응하는 수준의 학생들에게 적절히 제시하여야 할 것이다.

Although computer technology has a great potential for improving mathematics learning practice, it rarely used in mathematics classroom. The purpose of this study is to suggest the future direction for research in mathematics computer technology. First, there has to be a research on mathematics curriculum that take computer technology into account. Second, research on teaching sequence for certain content area is needed. Because computer technology would change the order of teaching sequence. Third, how students would learn with computer technology? how do they acquire knowledge and make sense of it? Fourth, how could we assess the learning with computer technology? Most of all, because teachers play a key role to succeed in educational reform, they have to be familiar with computer technology and software to introduce it into mathematics learning and to use it properly.

Statistical thinking has a broad definition but focuses on the context of regression modelling in the present study. To foster students' statistical thinking within the context, teaching should no longer be seen as transfer of knowledge from teacher to students but as a process of engaging with learning activities in which they develop ownership of knowledge. This study aims at collaborative learning contexts; students were divided into small groups in order to increase opportunities for peer collaboration. Each group of students was asked to do a regression project after class. Through doing the project, they learnt to organize and connect previously accrued piecemeal statistical knowledge in an integrated manner. They could also clarify misunderstandings and solve problems through verbal exchanges among themselves. They gave a clear and lucid account of the model they had built and showed collaborative interactions when presenting their projects in front of class. A survey was conducted to solicit their feedback on how peer collaboration would facilitate learning of statistics. Almost all students found their interaction with their peers productive; they focused on the development of statistical thinking with concerted effort.

본 연구는 진보주의 교육과 구성주의 교육이 학습자의 주관적 지식을 강조한다는 측면에서 공통점이 있으며, 이 두 교육 사조로부터 도출된 교육 원리가 수학교육 연구와 현장에 채택되어 적용될 때 유사한 문제점 또는 부작용이 발생한다는 문제의식을 전제로 수행되었다. 주관적 지식을 강조하는 진보주의와 구성주의는 이를 교육 현장에 적용함에 있어 주관적 지식 강조의 의미, 그 목적 및 적용 방향을 분명히 할 필요가 있었다. 이 문제에 대해 먼저 과거 진보주의의 교육적 적용 방식에 대해 Dewey의 이론을 바탕으로 반성해보고, 이를 거울삼아 동일한 문제에 대한 현재 구성주의의 교육적 적용에 대해 비판적 성찰을 시도하였다. 이를 통해 구성주의에 대한 발전적 이해와 수학 교실에서 보편적 이론으로 자리매김할 수 있는 논의의 단초를 제공하고자 하였다.

This study investigates 55 preservice secondary mathematics teachers' situational understanding of functional relationship. Functional thinking is fundamental and useful because it develops students' quantitative thinking about the world and analytical thinking about complex situations through examination of the relations between interdependent factors. Functional thinking is indispensable for understanding natural phenomena, for investigation by science, and for the technological inventions in engineering and navigation. Therefore, it goes without saying that teachers should be able to represent and communicate about various functional situations in the course of teaching and learning functional relationships to develop students' functional thinking. The result of this study illustrates that many preservice teachers were not able to appropriately represent and communicate about various functional situations. Additionally, it shows that most preservice teachers have limited understanding of the value of teaching function.

Over the last three decades, there has been an increasingly strong emphasis on group-centered approaches to mathematics teaching. One primary responsibility for teachers who use group-centered instruction is to "check in", or intervene, with groups to monitor group learning and provide mathematical support when necessary. While prior research has contributed valuable insight for successful teacher interventions in mathematics group work, there is a need for more fine-grained analyses of interactions between teachers and students. In this study, we co-conducted research with an exemplary middle grade teacher (Ms. Green) to learn about fine-grained details of her intervention practices, hoping to generate knowledge about successful teacher interventions that can be expanded, replicated, and/or contradicted in other contexts. Analyzing Ms. Green's practices as an exemplary case, we found that she used exceptionally short interventions (35 seconds on average), provided space for student dialogue, and applied four distinct strategies to support groups to make mathematical progress: (1) observing/listening before speaking; (2) using a combination of social and analytic scaffolds; (3) redirecting students to task instructions; (4) abruptly walking away. These findings imply that successful interventions may be characterized by brevity, shared dialogue between the teacher and students, and distinct (and sometimes unnatural) teaching moves.

This narrative review explores the transformative potential of immersive virtual reality (IVR) in enhancing high school students' mathematics competence, viewed through the lens of the technological, pedagogical, and content knowledge (TPACK) framework. This review comprehensively illustrates how IVR technologies have not only fostered a deeper understanding and engagement with mathematical concepts but have also enhanced the practical application of these skills. Through the careful examination of seminal papers, this study carefully explores the integration of IVR in high school mathematics education. It highlights significant contributions of IVR in improving students' computational proficiency, problem-solving skills, and spatial visualization abilities. These enhancements are crucial for developing a robust mathematical understanding and aptitude, positioning students for success in an increasingly technology-driven educational landscape. This review emphasizes the pivotal role of teachers in facilitating IVR-based learning experiences. It points to the necessity for comprehensive teacher training and professional development to fully harness the educational potential of IVR technologies. Equipping educators with the right tools and knowledge is essential for maximizing the effectiveness of this innovative teaching approach. The findings also indicate that while IVR holds promising prospects for enriching mathematics education, more research is needed to elaborate on instructional integration approaches that effectively overcome existing barriers. This includes technological limitations, access issues, and the need for curriculum adjustments to accommodate new teaching methods. In conclusion, this review calls for continued exploration into the effective use of IVR in educational settings, aiming to inform future practices and contribute to the evolving landscape of educational technology. The potential of IVR to transform educational experiences offers a compelling avenue for research and application in the field of mathematics education.

This study conducted a survey to examine the knowledge formation and utilization of computer among beginning teachers of secondary school mathematics. We found that beginning teachers who had more experiences of taking computer utilization classes at teacher education institutes showed more interest in computer and saw the necessity and effectiveness of computer usage for teaching students. Teachers chose GSP the most among computer utilization knowledge learned in pre-service teachers program, and GSP is used the most in mathematics classes. However, they answered that computer is not so much available in class due to lack of hours and the relevant resources. Lastly, beginning teachers answered that the computer knowledge learned in in-service teacher program was more useful than that in pre-service. Thus, the professional development in utilizing computer should be improved through diversifying teacher training contents for beginning teachers as well as for pre-service teachers in teacher education institutes.

이 연구의 목적은 한국과 홍콩 초등학교 예비교사들의 학교수학에 대한 이해 정도를 조사하고, 교사교육 과정에서 강조되어야 할 지식의 성격에 대한 시사점을 얻기 위한 것이다. 이를 위해 초등학교 수학 교수(敎授)와 관련되면서 '무엇을', '왜', '어떻게'의 측면을 포괄하는 다섯 개의 문항을 선정하고, 한국과 홍콩의 초등학교 예비교사를 대상으로 심층면접을 실시하였다. 면접 결과 한국과 홍콩의 초등학교 예비교사들은 학교 수학의 원리에 대해 충분히 이해하고 있지 못하며, 초등학교 수학을 중등학교 수학 및 대학 수준의 수학과 연결시켜 이해하는 능력이 부족한 것으로 나타났다. 이 결과에 비추어볼 때 초등학교 예비교사 교육에서 더욱 강조되어야 할 것은 중등학교 및 대학 수준의 수학을 초등학교 수학과 연계시키는 것이라고 할 수 있다.

'교수학적 내용 지식(Pedagogical Content Knowledge)'의 개념은 '교수활동을 위한 수학 내용 지식(Mathematical Knowledge for Teaching: MKT)'의 핵심 요소들을 밝히기 위한 연구의 일환으로 많은 연구자들에 의해 확장, 발전되어 왔다. 특히 Ball(1993)은 교수활동에서 가시적으로 드러나는 교사가 알아야 할 수학에 관해 초점을 맞추어 왔는데, 본 연구에서는 MKT를 바라보는 또 하나의 대안적 관점으로서 '발달에 핵심적인 이해 (Key Developmental Understanding: KDU)'라는 개념을 제안하고 있다. Simon (2006)은 KDU란 일련의 교수활동을 통해 수행되고 다른 수학적 아이디어의 학습에 기초가 되는 이해 또는 개념이며, '등분할 조작'이 분수 개념의 KDU가 될 수 있음을 주장하였다. 본 연구에서는 예비 초등교사와의 면담을 통하여 '반복 분할 조작'과 '세 수준의 단위 구조'의 구성이 분수 곱셈에 대한 KDU가 될 수 있음을 제시하고 있다.
