Technical high school aims at educating students to acquire fundamental skill and technology required for being competent technicians, to be creative in adjusting themselves to the changing industrial society, and to do self-realization and find their ways toward the future on their own. To attain that goal and maximize learning effect, mathematics education is very important as prerequisite learning for technical subjects, as most technical courses in technical high school are basically based on mathematics. The purpose of this study was to discuss how mathematics education could be successfully linked to technical courses in an attempt to make it function properly as prerequisite learning for major subjects and facilitate students' technical learning. For that purpose, what problems the mathematics components of major subjects and the curriculum had was examined and the way to offer better education was presented. And there are some suggestions regarding mathematics education: First, technical mathematics should be newly inserted into technical high school curricula to help students learn major subjects in more efficient way. Second, most technical high schools are expected to just require tenth graders to complete a 10-stage mathematics course. In that case, they might find difficulties in learning major subjects when they are in their 11st and 12th grade. The curriculum should be designed to have 11st and 12th graders take mathematics education. Third, many students find a job after graduation, but the growing number of students go on to university to receive more education in the same field. Accordingly, there is a need to enlarge continuous progress plan, rather than completion-type one, to make students well-grounded technically. And mathematics should be taught in more classes as prerequisite subject for major courses. Fourth, mathematics elements necessary for each major subject should be outlined and announced to schools so that they could reorganize mathematics and major courses appropriately.

본 논문은 제7차 교육과정에서의 8-가 부등식 단원의 문장제 문제를 다음의 관점에서 분석하였다. 첫째, 7차 교육과정 교과서별 부등식 단원의 문장제 문제들은 소재별로 어떠한 분포를 보이며 어떠한 부분이 부족한가? 둘째, 실생활과 연계된 소재의 문제는 얼마나 되며 어떠한 실생활 상황과 연계되어 있는가? 셋째, 타교과와 연계된 소재의 문제는 얼마나 되며 어떠한 교과와 연계되어 있는가? 이와 같은 관점에서 현재 16종 교과서에 수록된 내용을 소재별로 분석하였고, 실생활 관련, 타교과 연계에 대해서 집중적으로 분석하였다. 이상에서 연구한 결과, 다양한 소재를 포함하지 못하고, 다양한 타교과와 연계되지 못한 교과서가 많다는 것을 발견하였다. 학생들의 창의성을 증진시키고 수학을 실용성을 이해시키기 위해 다양한 실생활 소재와 타교과 연계가 필요하다.

수학 교실에서 과정중심평가의 실현을 위해서는 수업의 설계자이자 실제적 운영자인 현장 교사가 역량 기반 과정중심평가를 적용한 수업을 어떻게 계획하고 실행하는지에 대한 연구의 필요성이 제기된다. 이에 본 연구에서는 초등 2학년 학생을 대상으로 역량 기반 과정중심평가를 적용한 실험 수업을 수행하여, 2015 개정 수학과 교육과정의 학생 평가로 강조되고 있는 과정중심평가에 대한 실제 수업에서의 적용 사례를 분석하였고, 이에 따른 학교수학 교육평가에서 과정중심평가가 지니는 교육적 의의를 탐색하였으며, 나아가 초등수학 교육 현장에의 적용 방안을 모색하였다. 본 연구의 시사점으로 2학년 초등수학 교실에서 실제적으로 적용 가능한 역량 기반 과정중심평가 수업을 구체화하는 방안을 실제적으로 살펴보고, 더불어 과정중심평가를 적용한 수업에서 각 학생들의 요구와 필요에 부합하는 개별적 피드백을 제공할 수 있는 현실적인 방법을 알아보았다는 것이다.

수학교육은 이제 국민대중교육, 교양교육으로서의 수학교육의 이념을 재발견하여 수학교육의 본래의 모습을 회복해야 할 시점에 와 있다. 오늘날 우리가 학교에서 가르치는 수학 지식은 어떤 성격의 지식이며 우리는 그러한 지식을 가르침으로써 인간을 어떤 상태로 만들려고 하는가\ulcorner 본고에서는 수학교육 사상의 뿌리를 탐색해 봄으로서 수학이라는 지식을 배우는 요한 목적은 실용성을 넘어 수학이라는 지식을 통하여 인간과 만물 이면에 있는 현상의 세계를 지배하는 실재를 깨달아 가도록 하는 인간교육의 구현에 있음을 밝히고, 그러한 이념을 오늘날 국민교육으로서의 수학교육이 우선적으로 지향해야 할 방향으로 제시하였다.

The purpose of this study is to help the efficient and practical teaching and learning of a mathematic subject in schools by comparing and analyzing the sixth and seventh curriculum of mathematics on the basis of the demand that the current curriculum should be improved, made, and adapted newly. This paper 1. studies the meaning of the curriculum and the theory of the curriculum of mathematics 2. looks into the history of the curriculum of mathematics from the first to the sixth. 3. compares an outline of the sixth and seventh curriculum. As a result, it exhibits the great difference in giving students choices for subjects and nullifying the meaning of the subject distinction, which means a new system with consistency based on the concept of a grade system instead of the present school system. 4. summarizes the result of comparing and analyzing the sixth and seventh curriculum which will be practiced from the year 2002 5. The beginning of the seventh curriculum in high schools will be from the year 2002 and the ministry of education is expected to take proper actions for its successful settlement, yet at this point this study gives some suggestions for its smooth and normal operation.

Problem Based learning(PBL) is a teaching and learning method to increase mathematical ability and help achieving mathematical concepts and principles through problem solving using the learner's mathematical prerequisite knowledge. In addition, the recent instructional situations or environments have focused on the learner's self construction of his learning and its process. In spite of such a quite attention, it is not easy to apply and execute PBL program actually in class. Especially, there are some difficulties in actually applying and practicing PBL in the areas of mathematics education in not only secondary school but also in college. Its reason is that in order to conduct PBL instruction constantly in real or experimental class there is no more concrete and detailed instructional content during the consistent and long period. However, to whom is related to mathematics education including instructors called scaffolders, investigation and recognition on the degree of the learner's acquisition of mathematical thinking skills and strategies is an very important work. By the reason, in this study, the instructional content was to be explored and developed to be conducted during 15 weeks in one semester, which was based on Problem Based Learning environment by the subject of the theories relevant to mathematics education in the college of education.

We introduce and discuss a new numerical method for solving system of second order boundary value problems, where the solution is required to satisfy some extra continuity conditions on the subintervals in addition to the usual boundary conditions. We show that the present method gives approximations which are better than that produced by other collocation, finite difference and spline methods. Numerical example is presented to illustrate the applicability of the new method. AMS Mathematics Subject Classification : 65L12, 49J40.
