We investigated the relationship of brain dominance with mathematics and science achievement. The participants were 131 middle school students (male: 74, female: 57). It was found that the above average group in mathematics and science achievement had the highest frequency with left lower brain (LLB) (mathematics: 33.8%, science: 35.0%), whereas the below average group in mathematics and science achievement had the highest frequency with right lower brain (RLB) (mathematics: 38.7%, science: 36.1%). The LLB score showed a significant difference between the above average group and the below average group in science (p<.05). In the correlational analysis, the LLB scores had the highest correlation coefficients (mathematics: r=.28, science: r=.26). The LUB scores had the second highest correlation coefficients (mathematics: r=.18, science: r=.24). These results suggest that LLB and LUB are related to mathematics and science achievement. Therefore, we insist that the assessment of mathematics and science achievement should consider brain dominance.

In this study, the case of error became the object of learning, and the investigator applied these cases to an actual class and established three study problems in order to achieve the purpose of this study. The results of analysis of students' errors in figure based on before achievement test are shown as follows: First, the most errors occurred in the figure was the ones from deficient mastery of prerequisite concepts and definitions. Specially, the errors from deficient mastery of prerequisite concepts and definitions have the majority. it is very high ratio even if it considers an influence of an evaluation question item. so, I think it is necessary to teach concept related figure above all. Second, as the results of application 'finding errors' to a class, there is a meaningful difference in the mathematical achievement and reasoning ability within significance level 5%. This means 'finding errors' is one of the teaching method that it develops the mathematical achievement and reasoning ability.

The purpose of this study is to investigate the effect of mathematics classes focused on mathematical problem posing activities on 10th grade students' mathematics achievement and affective characteristics of mathematics. This study was conducted in a total of 45 regular mathematics classrooms with 81 students from two classes through a nonequivalent control group design. The results of the study showed that the teaching method based on mathematical problem posing activities had a more positive effect on students' mathematics achievement and the affective characteristics of mathematics than the teaching method that focuses on problem solving. The teaching method based on problem posing activities proposed in this study could induce students' self-reflective learning motivation, which in turn gave them a more solid understanding of the mathematical concepts they had learned. In addition, it was found that students' problem solving ability, mathematical communication ability, and mathematical thinking ability were positively influenced by problem posing activities. Regarding the affective characteristics of mathematics, the mathematical problem-posing activity suggested in this study turned out to be a very effective strategy for improving students' interest in mathematics.

This study examines the learning styles of freshmen enrolled in a college of science and engineering, and analyses the relationship between learning styles and academic achievement in mathematics to provide basic data for the teaching-learning methods, which are more suitable to learning styles of students. For the purpose of this research, a reliability analysis of Kolb's LSI is applied to 282 freshmen enrolled in a college of science and engineering of the medium-sized university. The outcomes of this survey are followings. Firstly, students hold higher positions in the order of converger, assimilator, accommodator, diverger among 4 learning styles. Secondly, while there is a positive corelation between abstract conceptualization[AC] and academic achievement, there is a negative corelation between concrete experience[CE] and academic achievement. Thirdly, as for academic achievement in mathematics, converger is superior to assimilator and accommodator. Finally, the correlation between learning styles and academic achievement is different by demographic characteristics. Based on these results, this study suggests the necessity for various teaching-learning strategies, which are adjusted to both academic characteristics of mathematics and learning styles. Also, the need for teaching methods, which help students to develop effectively four learning cycles, is proposed.

Shanghai has been reported as the highest performing countries(economies) in PISA 2009 and PISA 2012. In this reason, we reviewed literatures related to educational system of Shanghai focusing on the mathematics education. Additionally, we analysed the results of PISA 2009 of mathematics domain between Korea and Shanghai to compare some differences between two countries. As a result, we discovered the followings: 1) Comparing with Shanghai students, Korea students attained low performance in every sub-categories of mathematics abilities indicated in the PISA framework. 2) In PISA 2009 Framework, Korea students produced low achievement than Shanghai students in sub-categories of "reflection". 3) In PISA 2012 Framework. Korea students attained low performance than Shanghai students in sub-categories of "formulating". Consequently, it gave us insight into the idea that school mathematics in Korea should use authentic context to help students improve their competencies "reflection" and "formulating".

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.

본 연구는 학습 구조차트 구성을 통하여 고등학교 수학의 학습내용을 구조적 ${\cdot}$ 체계적으로 조직화시켜 학생들로 하여금 학습 내용의 효과적인 이해와 상호 관련성을 촉진시키고 학습 내용의 조직화 및 구조화 활동이 고등학생들의 학업에 미치는 영향을 조사하는데 그 목적이 있다. 본 연구에 따르면 수학 학업성취도가 상인 학생은 문제풀이시 머릿속에서 차트를 그리게 되고 여러 가지 개념을 나열하여 조작할 수 있는 능력이 생겼으며 문제 유형에 맞춘 학습 보다는 어떤 개념들이 문제풀이에 사용되었으며 이러한 개념들이 어떻게 나열되는지에 대한 학습으로 관심이 전환되었다. 수학학업 성취도가 하인 학생들은 학습 구조차트의 구성에만 만족하는 편이며 선행지식의 부족으로 복합적인 개념의 문제풀이에 있어서는 여전히 어려움을 경험하고 있었다. 성적이 낮은 학생일수록 개념에 대한 구조화와 조직화에 대한 어려움이 많은 것으로 보여 이들 학생들에 대한 장기적인 연구가 필요하다고 본다.

We discuss the effect of ability grouping calculus courses based upon student's proficiency of the subject and their collective examination of midterms and finals among mid-level and low-level classes. We assess incoming freshmen at Seoul National University of Technology(SNUT) of their proficiency in calculus and assign them to the appropriate levels within the course(i.e., high-level, mid-level, low-level). We found that this was beneficial to both students and instructors. Instructors can easily determine the pace in which each class should be kept, and students can quickly adapt to the learning environment.

오늘날과 같은 지식 정보화 사회는 지식과 정보를 기초로 한 사회활동이 주를 이루고 있다. 그래서 교육현장에서도 학습자는 컴퓨터를 이용하여 정보를 수집하고 처리하는 정보의 주체로 인식되어지고 있다. 특히 수학 교과 내용 중 도형 영역은 컴퓨터를 이용하여 다양한 시각적 경험과 탐구 기회를 제공하는 것이 매우 중요하다. 이를 실현하기 위한 방법으로써 여러 가지 방법이 있지만, 본 논문에서는 Sketchup이라는 상용 소프트웨어를 활용하여 도형 영역에 적용시켜 활용하는 방안에 대해 연구하였다. 학생들이 수학을 재미있고 쉽게 생각할 수 있는 방안을 내세우기란 쉽지 않지만, 이 연구의 결과로부터 수학과목의 도형영역에 대한 수학적 사고력과 성취도를 높이고 Sketchup과 같은 탐구형 소프트웨어의 효과적 활용 방안을 마련하고, 이를 통해 수학에 대한 긍정적인 인식을 마련할 수 있는 기틀이 되고자 한다.

We surveyed statistically the freshmen's achievement of the first year mathematics courses in Kwangwoon University, which were opened at the first semester of academic year 2006. In doing so, we classified the freshmen according to the Mathematical Area 'ga' or 'na' and the Natural Science or Social Science Area of Korean Scholastic Aptitude Test(KSAT) which they have chosen. We found that the freshmen who have chosen the Mathematical Area 'na' and the Social Science Area have the serious problem in studying the freshmen's math courses.
