In spite that spatial ability has been recognized as an important element of academic achievement in engineering studies, researches on the topic are rather limited in Korea. In this study, the relationship between spatial visualization skill and academic achievement of engineering students was investigated based on the several variables such as gender, high school education background and college course achievement. The result showed that there were significant relevance between spatial visualization skill and gender, high school type, achievement of high school level math & physics, and college course work grade of computer graphic and capstone design. According the case study, from the entry time of engineering college, support programs to reinforce spatial visualization skill are required for lower skill groups such as female and graduate from art course in high school. Also, college curriculum such as Engineering graphics, Capstone design are substantial to improve spatial visualization skill. However, more diversified sample groups and research methods are required in order to draw in depth results.

Math teachers are very short of computer tools and manipulatives to use in geometry classes of middle schools for the development of spatial abilities. At most they can ask student to make regular polyhedrons for helping the students to understand by concrete experience, but this experience is not enough to develop spatial abilities in spatial figures including the regular polyhedrons. This article is to introduce instructional materials for development of spatical ability in the regular polyhedrons using computer software, Geometer's Sketchpad. In this article, students can imagine the whole figure through the parts of a plane figure and think of the parts from the solid figure by free movement from 2 dimensions to 3 dimensions, or from 3 dimensions to 2 dimensions. Also, the instructional materials devised in this article will be good to enhance spatial abilities because the relation of 1-1 correspondence in the movement of the parts can be conserved and observed precisely, which is very hard to demonstrate and visualize by paper-and-pencil. It is recommended that this kind of materials should be developed in various ways for teachers to use them directly in their geometry classes.

Recently our educational methodologies have been changed to an open, student-centered structure. Mathematics is now learned through experiential interaction and less emphasis is placed on abstract theories. For example, the axioms of the geometry in the middle school curriculum have been expressed by using symbolic letters. Students find these abstractions very difficult and it hinders their ability to grasp the significance of geometrical concepts. In an effort to simplify these abstract concepts and enhance the students interest and ability to learn, the GSP (Geometry Sketchpad) is proving to be a useful and effective tool. First, Second and third grade students have found the GSP to be extremely useful. While the pad has no sound function it still enables the students to freely change diagrams without disrupting the integrity of the program. There is also a running order of instructions at the bottom of the screen to facilitate the step by step understanding of mathematical procedures. This function makes the program ideal for use by teachers, students and even beginners. Anyone experiencing difficulty can get immediate assistance from the guidebook which is located at the back of each program. Allowing individuals to manipulate and actually see the changing deductions and axiom proofs on the computer screen provides them with immediate feedback and reinforcement. It also enhances their overall interest in learning geometry. The use of the GSP is proving to be an innovative and effective tool in facilitating the transition of mathematics into an open, student-centered educational forum.

This study investigated the academic achievement of science and high school students according to the characteristics of R&E activities in mathematics and science. In addition, based on the survey results, the correlation between R&E activity characteristics and mathematics and science academic achievement was studied through correlation analysis and factor analysis between subjects. There was a difference in academic achievement in mathematics and science according to the characteristics of the R&E activity area, and the experience of R&E activity was found to be closely related to the academic achievement of related subjects. Depending on the area of R&E activity, mathematical and scientific academic achievement was found to be two factors: mathematical logic and natural understanding. Natural understanding factors significantly influenced students' academic achievement in mathematics, physics, and life sciences, and mathematical logic factors significantly influenced the academic achievement of students in chemistry and earth science subjects. In particular, mathematical logic ability was concentrated in excellent physics class students, and natural understanding ability was concentrated in excellent life science class students. Since the characteristics of the R & E activity area greatly influence the academic achievement of mathematics and science, it will significantly contribute to the selection and operation of the R & E activity area of science high school students.

본 연구는 초등 수학영재와 일반학생을 대상으로 정의적 특성과 수학적 추론 능력에서 어떠한 차이가 있는가를 알아보고, 이를 바탕으로 초등 수학영재와 일반학생의 정의적 특성과 수학적 추론 능력과의 관계를 비교 분석하는 것이다. 연구대상은 5학년의 영재 97명과 일반학생 144명이다. 검사도구로는 정의적 특성 검사지와 추론능력 검사지를 사용하였다. 본 연구의 결론은 다음과 같다. 첫째, 수학영재는 일반학생보다 정의적 특성의 하위 요소인 학업적 자아개념, 태도, 흥미, 수학불안, 학습습관에서 모두 긍정적인 인식을 지녔고, 수학적 추론 능력에서도 일반학생보다 능력의 정도가 높았다. 또한 수학영재는 정의적 특성의 학업적 자아개념, 태도, 흥미, 학습습관은 추론 능력과 정적인 상관관계를 가지고 있었으며 수학불안은 부적인 상관관계를 가지고 있었다. 둘째, 수학영재는 정의적 특성의 하위 요소 중 수학불안이 수학적 추론 능력에 부정적인 영향을 미치는 것으로 나타났는데, 이를 통해 수학 영재들의 추론 능력을 향상시키기 위해서는 수학 불안을 줄이는 실질적인 여러 방안을 모색할 필요가 있음을 알 수 있다. 셋째, 일반학생들은 정의적 특성의 하위 요소 중 흥미가 수학적 추론 능력에 영향을 주는 것으로 나타났는데, 따라서 교실 수업에서 일반학생들의 수학교과에 대한 흥미를 높여주는 적절한 방법에 대한 교수 학습 구안 및 적용을 통해 수학적 추론 능력의 향상을 도모할 수 있다.
