요즈음 수학 수업에서 협동 학습을 활용하여 문제 해결을 하는 경우가 많이 늘었다. 학생들이 소집단에서 함께 활동하면 더 나은 문제 해결자가 된다는 것을 알기 때문이다. 그러나 학생들에게 협동적인 상황에서 문제 해결을 하게 하면서 그 평가는 개인 평가나 전통적인 평가에 그치는 경우가 많다. 소집단 협동 학습은 소집단의 구성원이 협동을 할 때 그 효과가 큰 것이며, 소집단 협동 학습에서의 평가는 소집단에 있는 학생들이 수행한 것을 참되게(Authentic) 평가하여야 문제 해결에 대한 올바른 정보를 얻을 수 있고 각 학생들로 하여금 협동 학습에 적극적으로 참여하여 문제를 해결하게 할 수 있다. 만일 협동적인 문제 해결을 하였는데 개인 평가를 실시한다면 학생들은 집단에서 협동할 필요성을 적게 느끼게 되어, 학생들은 협동 학습에 적극적으로 참여하지 않으려 할 것이다. 1990년대 수학교육에 많은 영향을 끼치고 있는 NCTM의 Curriculum and Evaluation Standard for School Mathematics에서도 수학 지도 방법과 평가 방법이 일치하여야 한다고 강조하고 있다. 본고에서는 이와 같은 필요성에 의거하여 수학과 소집단 협동 학습의 유형을 알아보고, 협동적 문제 해결의 평가 방법을 알아보고자 한다.

The purpose of this study is to investigate the longitudinal impact of the engagement of private tutoring on student achievement and the influence of the engagement of gifted education on the effect of private tutoring by applying hierarchical linear growth modeling technique on the KELS (Korean Education Longitudinal Study) data. For the analysis, we used KELS data including the score of Mathematics achievement from 2005 to 2007 in order to get useful variables like whether or not to engage private tutoring, weekly time and monthly cost of private tutoring, the experience of gifted education, gender, prior achievement of 6th grade, parents' monthly income, internal motivation and self-efficacy. The sample consisted of 4,435 7th graders from Korean middle schools who were included in the KELS and have the data available to a significant dataset having no missing values include. The result suggest that the private tutoring experience predicted students' high Mathematics achievement and the interaction between grade and private tutoring time and cost has negative impact on the mathematics achievement. In contrast, it was found that the experience of gifted education has negative impact on the growth of mathematics achievement, but positive impact on the effect of private tutoring cost on the mathematics achievement. In other words, the experience of gifted education shows affirmative impact on the effect of private tutoring cost on the mathematics achievement indirectly. On the basis of this results, we discussed deeply the effect of private tutoring on the Mathematics achievement and the influence and its meaning of the experience of gifted education on the effect of private tutoring.

발생적 원리는 수학을 공리적으로 전개된 완성된 것으로 가르치는 형식주의의 결함을 극복하기 위하여 제기되어온 교수학적 원리로, 수학을 발생된 것으로 파악하고 그 발생을 학습과정에서 재성취하게 하려는 것이다. 특히, 수학을 지도함에 있어서 역사적으로 발생, 발달한 순서를 지켜 지도해야 한다는 것이 역사-발생적 원리로, 수학이 역사적으로 발생, 발달 되어온 역동적인 과정을 학생들이 재경험해 보게 하기 위해서는 이러한 일련의 과정을 효과적으로 설명할 수 있는 교수-학습 방법이 필요하다. 변증법적인 방법론은 헤겔에 의해서 꽃을 피운 철학으로, 정일반일합(正一反一合)의 원리에 따라 사물의 발생과 진화 과정을 역동적으로 설명할 수 있는 방법론이다. 따라서, 본 연구는 초등학교에서 역사-발생적 원리에 따라 수학을 지도할 수 있는 방법으로 변증법적인 방법을 고찰하여, 역사-발생적 원리의 수학 교수-학습 방법에 대한 시사점을 얻고자 한다.

최근 수학교육에서는 네덜란드의 수학교육이론인 현실적 수학교육(Realistic Mathematics Education: 이하 RME) 이론에 대한 관심이 증대되고 있다. RME 이론의 관점에서 학생들은 만들어져 있는 수학을 수용하는 사람이 아니라 스스로 모든 종류의 수학적 도구와 통찰을 개발하는 활동적 참여자로서 다루어져야 한다. 따라서 수학 학습은 수학화될 수 있는 풍부한 맥락으로부터 시작해야하며, 이러한 수학화를 실제(reality)에 둘 수 있도록 기여할 수 있는 교재로 시작해야 한다. 최근 발간된 'Mathematics In Context(이하 MIC)'는 RME 이론을 반영한 중등학교용 교과서로 맥락 문제가 그 중심이 되고 있으므로 RME 이론의 구체화된 실제를 볼 수 있는 예가 될 수 있다. 지금까지 Freudenthal의 교육철학을 소개하는 문헌 연구를 비롯하여 RME 이론을 기반으로 하는 교수 학습의 효과 분석에 관한 연구가 초등학교를 중심으로 이루어지고 있으나 중등학교 이상의 수준에서 수행된 RME 관련 연구가 부족한 실정이다. 이에 본 연구는 RME 이론이 중등학교 이상에서 수행되는 예를 찾기 위해 MIC 대수 교과서 중 'Comparing Quantities(Kindt, Abels, Meyer, & Pligge, 1998)'를 중심으로 Treffers(1991)의 다섯 가지 교수 학습 원리(구성하기와 구체화하기, 여러 가지 수준과 모델, 반성과 특별한 과제, 사회적 맥락과 상호작용, 구조화와 연결성)가 어떻게 구현되고 있는지 살펴보고자 한다. RME의 수학 학습 이론은 학생들이 맥락과 모델을 사용하면서 다양한 수준의 수학화를 통해서 자신의 수학을 개발할 수 있도록 하는 것이다. MIC 교과서는 맥락 문제와 여러 가지 해결 전략을 제시함으로써 그러한 수학 수업을 할 수 있도록 안내하는 교재가 될 수 있다.

Common Core State Standards for Mathematics(CCSSM) is a blueprint for school mathematics in 2010s of the United States. CCSSM can be divided into two major parts, the standards for mathematical content and the standards for mathematical practice. This study focused on the latter. Mathematical practice comes from the mathematical process in 'Principles and standards for school mathematics(NCTM, 2000)' as well as the mathematical proficiency in 'Adding it up(NRC, 2001)'. It is composed of eight standards which mathematically proficient students are expected to do. From Korean perspective, it can also be comparable with the mathematical process which contains mathematical problem solving, mathematical reasoning, and mathematical communication and was provided by the 2009 revised national curriculum for mathematics in Korea. However, few focused the standards for mathematical practice among the studies related to CCSSM in Korea. Moreover, there is a study that even ignores the existence of the standards for mathematical practice itself. This study aims to understand the standards for mathematical practice through analysing the document of CCSSM and its successive materials for implementing the CCSSM. This understanding will help effective implementation of the mathematical process in Korea.

This study was carried out to investigate effects of the mindmap note-taking for the formation of the mathematical concepts structure and the matjematical creativity. Two classes were randomly chosen for this study from the third grade students of a middle school located in a medium size city. Thirty one lecture hours of the mindmap note-taking on the quadratic equation and functions were administered to the experimental class of 41 students, while same lecture hours of the ordinary instruction on the same contents were administered to the control class of 40 students. It was shown from this experiment that there ware significant evidences of improvement both in the formation of students' mathematical concepts structure and mathematical creativity through the mindmap note-taking lecture. Hence, the mindmap note-taking lecture is suggested for the improvement in the formation of student's mathematical concepts structure and mathematical creativity.

The purpose of this study was to examine the effect of essay writing-centered mathematics instruction on problem solving and mathematical deposition in the elementary school. For the present study, two 6th grade classes with equivalent achievement in terms of problem solving and mathematical disposition based on the pretest. A total of 15 mathematics lessons focused on writing activities were administered to the experiment group for two months, while the textbook-based traditional lessons were given to the comparison group. Both quantitative and qualitative methods were adopted to analyze the data. The results of the present study showed that essay writing-centered mathematics teaching is statistically superior that the textbook-based mathematics teaching with respect to students' problem solving and mathematical disposition. In addition, it was evidenced that essay writing-centered mathematics instruction makes an influence on students' perceptions toward essay-based assessment in a positive way.
