수학과의 평가는 수학의 학습 내용에 대한 학생들의 성취도를 다양한 유형의 평가기법을 이용하여 파악하고, 이를 통해 수학교육의 질을 관리하는데 그 목적이 있다. 그러나 지금까지의 대부분의 평가는 수학교육의 본질이라 할 수 있는 학습자의 수학적 사고력을 제대로 측정하지 못하고 단편적인 수학적 지식을 결과 위주로 평가하는 데 만족해 왔다. 한편으로는 지극히 교과서적이고 인위적인, 단지 문제를 위한 수학 문제는 수학 무용론을 부추기기도 하였다(박경미, 1998). 이와 같은 수학과의 위기를 탈출하기 위해서는 결과만을 고려하는 선다형의 문제가 아닌 과정을 중시하는 서술형 주관식 문제, 기능 위주의 고립된 수학적 지식을 측정한 학업성취 결과보다는 수학 학습에 대한 태도나 노력, 관심, 탐구적 활동 그리고 성향 등 정의적 영역의 평가가 절실히 요구된다. 따라서 기존의 지필 검사를 뛰어넘는 다양한 평가의 틀이 요구된다 하겠다. 이런 점에서 1999학년도부터 시행되고 있는 고등학교에서의 수행평가는 변화하는 교육기조의 교수 ${\cdot}$ 학습에 대한 적절한 평가의 한 방법이라 생각된다. 이에 본 연구는 다양한 평가의 틀 가운데 수학과 수행평가에 관한 고찰을 통해서 현장에서의 수행평가활용 방법을 찾는데 있다.

In this paper, we surveyed the attitudes of engineering students in 6 universities in Chungcheong area to mathematics by 5-scale degrees and performed a comparative analysis of the results. The results revealed a number of meaningful points which should be applied to college mathematic education. On the basis of the results of the analysis, we made the following suggestions; 1) It is necessary to pay much attention to the students who have insufficient math ability 2) Special teaching methods are required for Freshman engineering students 3) Practical teaching strategies should be developed for engineering students that are based on the research on their math background 4) We should develop more materials in the area of mathematical concept image 5) More attention should be paid to the relation between math concepts and engineering concepts. Besides the above suggestions, we proposed that more research about students' math background and attitudes should be conducted for more efficient college math education.

One of the characteristics in math -abstract concept- makes the students find difficulties in understanding general ideas about math. This study is about how much do the modeling lessons using the technical instruments which is based on the realistic mathematical theory influence on understanding the mathematical concept. This study is based on one of the contents the first grade of middle school students study, the function, especially the meaning of it. Some brilliant students being the objects of this study, mathematically experimental modeling lesson was planned, conducted. Survey on the students' attitudes about math before and after the modeling classes and Questionnaire survey on the effectiveness about the modeling class were conducted and their attitudes were recorded also. This study tells that students show very meaningful changes before and after the modeling class and scientific knowledge seems to be very helpful for the students to understand the mathematical concept and solve the problems. When scientific research and development get together with mathematics, students will be more motivated and be able to form the right mathematical concept easily.

The purpose of this study is to examine not only students' cognition in the mathematical error-finding activity of the concept of irrational numbers, but also the students' learning stance regarding the use of errors and a teacher's questioning strategies that lead to changes in the level of mathematical discourse. To this end, error-finding individual activities, group activities, and additional interviews were conducted with 133 middle school students, and students' cognition and the teacher's questioning strategies for changes in students' learning stance and levels of mathematical discourse were analyzed. As a result of the study, students' cognition focuses on the symbolic representation of irrational numbers and the representation of decimal numbers, and they recognize the existence of irrational numbers on a number line, but tend to have difficulty expressing a number line using figures. In addition, the importance of the teacher's leading and exploring questioning strategy was observed to promote changes in students' learning stance and levels of mathematical discourse. This study is valuable in that it specified the method of using errors in mathematics teaching and learning and elaborated the teacher's questioning strategies in finding mathematical errors.

학교수학을 가르치고 배우는 과정에서 교사의 역할은 기술 공학의 활용으로 변화하고 있다. 기술공학의 역할은 학생들로 하여금 수학에 대한 태도를 변하게 하여, 탐구적이며 창의적인 방법으로 수학을 공부하는데 열의를 갖도록 한다. 반면에 현재의 수학교수는 여전히 보수적이며 환경의 변화에 더디게 적응하고 있으나, 세상이 상당히 빨리 변하고 있으므로 기술공학을 활용하여 현재의 교수를 개선해 나가야 하겠다. 변화에 대한 인식과 갈망은 학습자료, 재정 상태, 그리고 기타 여러 가지 요인보다도 훨씬 중요하며 가장 중요한 것은 교수관점 및 교수견해의 변화에 대한 의지이다. 교사가 기호연산 실행 조작이 가능한 수학 학습용 컴퓨터 응용 소프트웨어와 이들을 탑재한 휴대용 수학학습 전용기를 중등학교수학에 적용할 경우, 수학교육에서 신중히 고려해야 할 것은, 첫째 모든 수준의 학생들을 격려하며, 둘째 대상 영역의 수학학습 내용을 이해하도록 기술공학을 활용한 새로운 교수 기법에 접근할 수 있어야 한다는 점이다.

The purpose of this study was to investigate the effects of mathematical instruction using GSP program on the symmetrical figures learning and self-directed learning attitude. According to the pretest result, the experiment group and the comparison group showed to be homogeneous groups. The experiment group has learned symmetrical figures for 9 hours using the GSP program and the comparison group has learned for 9 hours using the traditional method(paper and pen lesson). As the posttests, self-directed learning attitude test and symmetry figure understanding test were performed. The results obtained in this research are as follows; First, there was a significant difference in symmetry figure understanding test between the experiment group which learned through GSP program and the comparison group which learned through traditional method. Since there showed a very high achievement in the experiment group which learned using GSP, it can be inferred that GSP was very effective in the lessons of symmetrical movements. Second, there was a significant difference in self-directed learning attitude test between the experiment group and the comparison group. This seems to be because the length of the sides of the figures, size of the angles of the figures etc can be verified instantly and the students can correct by themselves and give feedbacks when they use GSP program. Students preferred drawing using the GSP over drawing using rulers and pencils, and they showed interest in the GSP program and they did not have burden in being wrong in their study and studied in various methods. And as they become familiar with the GSP program, they even studied other contents beyond the scope presented in the textbook.
