본 연구는 초등학생에게 알맞은 수학과 PBL(문제중심학습)의 목표와 모형을 개발하여 실제 수업에 적용 분석함으로써 수학 교과에서의 PBL에 대한 실천적 이해와 구체적인 방안을 제시하는 것을 목적으로 한다. 본 연구는 7차 개정 수학과 교육과정의 목표를 구현할 수 있도록 지식, 기능, 태도 영역으로 구분하여 10가지 목표를 설정하고 수학과 PBL 목표 기준을 표로 제시하였다. 또한 기존의 PBL 모형을 수정 보완하여 초등학교에 적합한 수학과 PBL 모형을 개발하고자 수학적 의미화, 수리 정보 수집 단계를 추가하고 정리단계를 강화한 초등학교 수학과 PBL 모형을 제시하였다. 이를 초등학교 4학년 소수 단원에 두 차례의 현장 적용을 하는 동안 4명의 개별 학생들의 수학과 PBL 목표 도달여부와 반응을 살펴보았다.

This study investigates the relationship of mathematics anxiety and achievement in college mathematics for engineering major freshman students. An revised and modified 30-item version of the Mathematics Anxiety Scale(MAS) was completed by 176 university engineering students enrolled in introductory calculus courses offered by the department of mathematics. Correlational analysis indicated complex interaction patterns between mathematics anxiety and mathematics achievement, depending on the level of anxiety. The results from this study confirm the negative correlation between mathematics anxiety and mathematics achievement in college mathematics for engineering major student, and also those support the claim that the relationships between mathematics anxiety and achievement have non-linear patterns.

The purpose of this study is to diagnose the current states and the problems of student assessment of Elementary School Mathematics. For that purpose, this study conducted a survey and had the individual interviews. The surrey items consisted of the six main parts: questions about the development of assessment tools, the method to assess, the grading, the special supplementary courses, the opening of learning effect, and the follow-up guidances. The results of this study are as the follow First, elementary teachers depended heavily on internet sites for developing assessment problems. Second, elementary teachers made use of a performance assessment, a unit assessment, and a term examination at ordinary times. Third, unit assessment was largely referred for grading by elementary teachers. Fourth, in selecting the students for the special supplementary courses, both criterion-referenced assessment and norm-referenced assessment were considered. After finishing the special supplementary courses, additional tests were usually taken. Fifth, elementary teachers took a negative attitude in opening of learning effect. specialty opening of test paper to parents of students was done under 30%. Sixth, fellow-up guidances were the most through the classroom guidances. but consulting with parents of students was not frequently conducted by teachers.

본 논문은 예비교사들이 함수교육과 관련된 subjective-matter knowledge와 pedagogical content knowledge를 어떻게 효율적으로 의미있게 학습하고 발전시키는 가에 대하여 조사하였다. 함수의 기본개념과 원칙, 그리고 그들이 어떻게 조직되었는지를 이해하는 능력과 의미있는 함수학습이 가능하도록 그들을 표현하고 구성하는 능력을 증진시키기 위하여 본 연구에서는 구성주의와 협동학습에 기반 한 학습방법을 채택하였다. 사전, 사후테스트와 인터뷰를 통하여 평가한 결과 소그룹 구성원들과의 상호작용 결과를 전체 구성원과의 토론을 통하여 학습하는 과정에서 보다 깊이 있고 확장된 subject-matter knowledge와 다양한 pedagogical content knowledge를 획득하게 되는 결과를 얻게 되었다.

'Calculus for Life Science' is one of the calculus courses for students majoring life science in Seoul National University. Contrary to the other calculus courses for students in natural sciences and engineerings, in 'Calculus for life Science' we have primarily chosen computer-based curriculum that is useful to life science and so we have tried to fulfill the requirements of the students majoring life science. Like this, we are of the opinion that there are diverse requirements in life science as well as other majors in basic mathematical education of the university. Upon this view, in this research, we consider the present conditions, the points at issue and study improvements of them. In section II and III, we introduce briefly the present 'Calculus for Life Science' focused on the curriculum. In section IV, according to the course evaluations and questionnaire, we make an analysis of the present condition and the points at issue of 'Calculus for Life Science'. In section V and VI, we present the improvements of the curriculum and the several education environments.

Because all areas of mechanical engineering involves the use of mathematics, mechanical engineers need mathematical understanding and skill enhancement. To achieve the effective mathematics education for mechanical undergraduate students, it should reorganize the important subtopics of mathematics. In this paper, we explore the direction of the development of mathematics education for mechanical engineers by analyzing the teaching hours of each topics in the mathematics and by comparing the results with significance analysis of expert survey. To do so, syllabuses of mathematics courses of the selected mechanical engineering departments were analyzed and the survey responses of professionals in the Korean Society of Mechanical Engineers were also investigated. Finally, the revision of mathematics curriculum in the mechanical engineering was proposed.

The purpose of this study is to examine how academic achievement in college math courses differ depending on when the course takes place. As a result, based on years of data analyses on students' academic achievement, it was affirmed that achievement levels differ due to environmental factors despite the diverse efforts of instructors and students. By further analyzing the causes of these differences, this study suggests solutions for improving the different academic achievement levels.
