This study examines the longitudinal effect of goal perception, mathematics class factors(perceptions about mathematics teachers (PMT), mathematics classroom attitude), and mathematics academic achievement. This study consists of three research models. First, we examined the longitudinal change of goal perception, perceptions about mathematics teachers (PMT), mathematics classroom attitude, and mathematics academic achievement using latent growth curve modeling. Secondly, the slope of PMT is a critical mediator between the slope of goal perception and the slope of mathematics academic achievement. Finally, the slope of mathematics classroom attitude is a critical mediator between the slope of goal perception and the slope of mathematics academic achievement. Data were extracted from Seoul Education Longitudinal Study from 2010 to 2012 (in three waves), and the analysis used by middle school students, measured by 4163 students of the three-wave surveys. Latent growth modeling was applied to verify the research problems. The results of the research are as follows. First, the slope of goal perception had positive and significant effects on the slope of PMT and mathematics classroom attitude, respectively. Second, the slope of PMT and mathematics classroom attitude had positively significant effects on the slope of mathematics academic achievement. Finally, it was confirmed that the slopes of PMT and mathematics classroom attitude are critical mediators between the slope of goal perception and the slope of mathematics academic achievement.

본 연구에서는 교육과정 질 관리의 측면에서 의무교육 대상인 초등학교와 중학교의 수학 교육 실태를 분석하여 교육과정의 투입, 과정, 산출 단계의 측면에서 질 관리가 되어야 할 주요 내용을 중심으로 학생, 학부모, 교사 대상 설문을 실시하였다. 설문 결과, 첫째, 투입 단계에서 초등학생들은 학습량이, 중학생은 내용 수준의 어려움이 있음이 나타났다. 둘째, 과정 단계에서 초등학교 교사들이 중학교 교사들에 비하여 교육과정 상의 교수 학습 방법을 더 잘 이행하고 있는 것으로 나타났다. 셋째, 산출 단계에서 학생 및 학부모의 인지적 영역과 정의적 영역의 만족도가 초등학교보다 중학교에서 낮은 것으로 나타났지만, 응답 평균은 두 학교급에서 모두 높은 편이었다. 이상을 고려하여 추후 새교육과정이 교육 현장에 적용될 때에 학교급별로 나타난 문제점을 해소할 수 있는 방법이 마련되어야 하고, 궁극적으로 교육과정 질 관리를 위한 수단으로서 교육과정이 개정될 수 있는 체제가 마련되어야 할 것이다.

As a researcher engaged in the mathematical education, mathematics teachers are interested in instructional methods. While it is unlikely that the viewpoints of individual mathematics teachers are reflected in making decisions on instructional purposes and instructional contents, a good many parts of instructional methods on mathematical facts are decided by individual teachers. This means that the role of mathematics teachers is given much weight in the mathematical education. Therefore, the mathematics teachers must not be excluded in all parts of the study of mathematical education. We studied the instructional methods of function concept, a central topic in school mathematics from the following perspectives. First, we examined the characteristics of the three(correspondence-centered, middle, dependence centered) viewpoints about the essence of function concept. And we should that which of them should be the viewpoint of instruction of function concept in school mathematics. Second, we investigated the questions regarding the process of function instruction in school mathematics and presented alternative instruction methods of function concept to solve the questions. Third, we postulated the importance of polynomial function, relating college mathematics in order to present the reason why the polynomial function is importantly treated in functional instruction of school mathematics.

The purpose of this study is to compare and analyze the impact on low-achievers in mathematics who studied mathematics using Blended e-learning and Personalized system of instruction after school. Blended e-learning is defined as the management of e-learning using the e-study run by the education office in local. Personalized system of instruction was proceeded as follows; (1) all students are given a syllabicated learning task and a study guide, (2) students study the material autonomously according to their own pace for a certain period of time, (3) the teacher strengthens the students' motivation through grading and feedback after students study a subject and solve the evaluation problem. The learning materials for Personalized system of instruction are re-edited the offline education contents provided by the blended e-learning to the level of students. The 118 $7^{th}$ grade students from the D middle school participated in this study. The results were verified by achievement tests before and after the study, as well as survey regarding their attitude toward mathematics. The results are as follows. First, Blended e-learning has more positive impacts than Personalized system of instruction in mathematics achievement. Second, there was no difference in mathematics achievement according to their self-directed learning between Blended e-learning and Personalized system of instruction. Third, both types utilizing Blended e-learning and Personalized system of instruction have positive effect on attitude toward mathematics, and there is not their difference between two methods of teaching and learning mathematics.

본 연구는 유클리드의 자료론(The Data)에 제시된 명제 94개의 가장 핵심적인 구성 원리에 기초하여 중학교 기하영역에서 '자료론'의 '자료(datum)'에 부합된 문제를 중학교 교과서를 중심으로 분석하고 이를 기초로 하여 자료(datum) 개발을 목적으로 한다. 이러한 연구 목적을 위해 다음과 같은 연구를 진행한다. 첫째, 자료론의 명제들은 '자료(datum)'라고 불리는 독특한 구조를 형성하고 있다. 이러한 구조에 대해 구체적으로 고찰한다. 둘째, 현재 중학교 교과서에서 다루어지는 기하 내용영역에서 자료로 분류할 수 있는 학습 자료를 분석하고 탐색한다. 셋째, 중학교 기하교육에 적용 가능한 전형적인 자료(datum)의 형태를 가지는 자료 개발하고 탐구한다. 이러한 연구 결과를 통해 학교현장에서 수학교육이 더 풍성해 질 것과 수학교육과정의 개정 및 교수-학습 개선에 의미 있는 시사점을 제공하리라 기대된다.

본 논문은 학교수학의 연계성에 대하여 체계적으로 비교하고 분석하였다. 또한 수학적 의미에 바탕을 둔 수평적 및 수직적 연계성을 분류하고 검토함으로써 학교수학에 관한 이론적 기반을 조성하고자 하였다. 지금까지 학교수학은 일반적으로 수직적 연계성에 중심을 두어 거시적인 차원에서 수학을 바라보았으나 본 논문은 수평적 연계성을 살펴봄으로써 미시적인 측면과 거시적인 측면을 함께 살펴보았다. 또한 인터넷을 활용함으로써 다양한 활동을 제공하고 특히 함수에 관한 교육과정의 변화를 모색한다. 그리하여 우리는 함수의 지도를 원활하게 할 수 있는 활동과 모델을 제시한다.
