신종 코로나바이러스(COVID-19)로 인한 비대면(Untact, 비접촉) 대학수학교육에서 적절하고 공정한 평가에 대한 문제가 제기되고 있다. 이를 위해 본 연구진은 2020년 여름 S대학에서 진행한 도전학기에서 '인공지능을 위한 기초수학' 강좌를 운영하면서 평가의 공정성을 보장하면서도 교육의 양과 질을 향상시킬 수 있도록, 온라인과 오프라인 평가를 혼용한 과정중심 PBL(Problem/Project-Based Learning, 문제/프로젝트 기반학습) 평가를 전면적으로 도입하였다. 그 결과, 해당 강좌를 수강한 대부분의 학생들이 예외 없이 관련 지식을 폭넓게 학습했음을 확인했으며, 학습자들로부터 언택트 시대에 보통의 온라인 강좌에 적용 가능한 이상적이고 공정하며, 합리적이고 동시에 효과적인 평가방법이라는 피드백을 받았다. 본 원고에서는 과정중심 PBL 평가 사례를 구체적으로 증빙과 함께 소개한다.

본 논문은 학생들이 모둠을 만들어 모둠원 간의 협의를 통해 문제를 만들고 문제를 해결하는 방법인 브레인라이팅 기법을 활용한 문제제기 수업 통하여 수학적 문제해결력과 창의력 신장에 미치는 효과를 알아보고, 흥미도 검사지를 통해 브레인라이팅기법에 의한 수학학습 수업이 기존의 수학학습과 어떠한 차이가 있었는지 알아보고자 했다. 실험결과 브레인라이팅 기법을 활용한 문제제기 수학학습이 문제해결력의 신장과 창의력의 하위 요소인 유창성과 독창성 신장에 효과가 있다는 것을 알 수 있었고, 브레인라이팅 기법을 활용한 문제제기 수학 학습이 학생들의 흥미도가 올라감에 따라 학생들이 문제를 풀이하는 과정에서 모둠원간의 협의 하고, 해결하는 과정에서 자신감이 높아졌음을 알 수 있었다.

The purpose of this paper is to present the history of the research in mathematics education, its characteristic and some theories as its results in France. The french research in mathematics education really began with the inauguration of IREM in the institutional aspect, referring to Bachelard in the epistemological aspect and to Piaget in the psychological aspect. It aimed at appreciating the mathematics education as a independent science and focused on the theoretical research through its own object(didactic system) and its own method(didactic engineering). Therefore, it can be characterized by the dense and elaborate theoretical arguments. Consequently, it is known that four major theories in french mathematics education were developed: the theory of didactic situations by trousseau, the theory of didactic transposition by Chevallard, the theory of conceptual fields by Vergnaud, the theory of tool-object dialectic by Douady. Among them, this paper is focused on the situation of institutionalization and the structurization of milieu in the theory of Brousseau and the motive of didactic transposition and the didactic time in the theory of Chevallard. In that the french research in mathematics education has been founded on its own theoretical models, it may contribute to us who envy the basic theories of mathematics education.

This study suggested a teaching method to improve intuitive understanding of the statistical basic concepts about the central limit theorem with experiment. It is very hard to understand about the concept of the central limit theorem in the school mathematics class. The result of this study experiment for the class of statistics education shows that the students and mathematics teachers were interesting at this experiment. They corrected their misunderstanding about the central limit theorem by discussion for the result of experiment with team members. I think that this study can help teachers to teach the students using the experiment method.

This study examines the effects of reflective journal writing on the mathematics self-efficacy in reciprocal peer tutoring. Participants were 38 high school students in Gyeonggi province who attended at a summer intensive mathematics course for 4 weeks. This study used a mixed method. SPSS 21.0 program was used to analyze the quantitative data, and the interviews, observational journals and reflective journals of 6 students were used to analyze qualitative data. According to the results, all the subcategories of mathematics self-efficacy, - mathematics problem-efficacy, mathematics success-efficacy, mathematics learning-efficacy, and mathematics subject-efficacy - improved except mathematics occupation-efficacy. In case of mathematics success-efficacy and mathematics problem-efficacy, students revealed the greatest improvement. In conclusion, reflective journal writing in reciprocal peer tutoring could be suggested as a treatment program to improve students' mathematics self-efficacy.

In this paper, we present a Krylov subspace based projection method for reduced-order modeling of large scale bilinear multi-input multi-output (MIMO) systems. The reduced-order bilinear system is constructed in such a way that it can match a desired number of moments of multi-variable transfer functions corresponding to the kernels of Volterra series representation of the original system. Numerical examples report the effectiveness of this method.

최근 국제 수학교육에서 가치(values)를 다루는 프로젝트나 연구물이 증가하고 있으나 우리나라에서는 소개된 것이 많지 않다. 본 연구에서는 Bishop(1996)의 '수학적 가치'와 '수학 교육적 가치'를 중심으로 체계적인 문헌 검토를 통하여 최종 66편의 논문을 선정하였고 연구시기, 프로젝트, 분석 대상, 연구 방법을 기준으로 연구 동향을 제시하였다.

본 연구는 최근 수학교육 연구 논문들의 연구 동향을 파악하기 위하여 2016년 이후의 수학교육 학술지 논문들을 대상으로 텍스트마이닝 기법 중 토픽 모델링과 트랜드 분석 기법을 활용하여 분석을 실시하였다. 분석 결과 빈도수가 높은 단어들을 조합하여 5개의 토픽을 추출하였으며 이를 통해 최근 활발히 이루어지고 있는 수학교육 연구 주제들을 파악할 수 있었다. 이는 다시 기 수행된 동향 연구들과 차이점과 유사한 점들을 도출할 수 있었는데, 이와 같은 동향 분석을 통해 최근 연구자들이 수학교육 연구에서 중요시 여기는 관점을 읽어 나감과 동시에 향후 주목하여야할 연구 주제 및 방향에 대한 시사점을 제공한다.

Through this study, we aimed to capture the nature of a mathematics method course, called "the Curriculum Development and Teaching Methods in Mathematics Education" which is a pedagogy course for teaching for secondary school mathematics taught at a university located in a south eastern part of South Korea. The research participants include three junior students who took the methods course and a local high school math teacher with two professors. The research has three parts. First, we designed a method course to prepare the junior or senior students for a teaching practicum. The individual students gave a mini lecture about a secondary mathematical topic as a course requirement. Second, the three students watched a classroom video-clip of the high school teacher and analyzed his instruction before the actual classroom visits. Furthermore, by "Let's Learn" program for students, the course was associated with a local community through the students and so that they could visit the teacher's classroom three times to observe his math classroom teaching. The students discussed the difference between their own mini lectures and the actual math classroom teaching to develop an understanding of what it entails to teach an actual math class. Third, the first author supervised the students' activities in the program including their report for it to bring out their findings to the class of the method course. We found out this method course provided the students with the experience of various aspects of actual math lesson as well as learning theories about the pedagogy for teaching for secondary school mathematics. We conclude that this course gives a model for the method course in mathematics education for secondary school mathematics.
