Many topics in science, especially, abstract concepts, relationships, properties, entities in invisible ranges, are described in mathematical representations such as formula, numbers, symbols, and graphs. Although the mathematical representation is an essential tool to better understand scientific phenomena, the mathematical element is pointed out as a reason for learning difficulty and losing interests in science. In order to further investigate the relationship between mathematics knowledge and science understanding, the current study examined 793 high school students' understanding of the pH value. As a measure of the molar concentration of hydrogen ions in the solution, the pH value is an appropriate example to explore what a student mathematical structure of logarithm is and how they interpret the proportional relationship of numbers for scientific explanation. To the end, students were asked to write their responses on a questionnaire that is composed of nine content domain questions and four affective domain questions. Data analysis of this study provides information for the relationship between student understanding of the pH value and related mathematics knowledge.

The purpose of this study is to investigate the factor for improving elementary and secondary students' positive experiences about science (PES). In-depth interviews with 32 students and 8 teachers from 8 elementary and secondary Science Core schools were conducted to explore the factors for improving the student's PES. The analysis of the results reveal that the eight key factors which had a decisive impact on a student's PES were 'practice-centered exploratory activities', 'student-led class', 'positive and professional feedback', 'construction of knowledge through exploration', 'class considering student's interest and aptitude', 'use of materials related to real life', 'smooth communication and collaboration in group activities', and 'appropriate difficulty in learning content'. There were also five environmental factors that affected these key factors: 'teacher's professionalism for science classes', 'science class environment', 'teacher community in unit schools', 'change in curriculum', and 'scientific activities other than regular classes'. Based on these results, the practical implications for improving the student's PES are suggested.

This study was concentrated on the development of the effective noise environmental education program(NEEP) for elementary student. And through this program, the student who is remaining as a spector or has not active attitude for noise problems will be encouraged to solve the troubles spontaneously. The object of this study was the two classes in H elementary school where is near to the Daegu international airport. One class that is a group for experiment has five NEEP lessons during five weeks in the time for the creative discretional activities. The other class, which was compared with the experimental group was given no lessons. NEEP was made on the bases that are the contents related with noise in 7th elementary education policy and the data developed by previous researchers. This program is containing basic concepts for noise and the effects of noise problems on human body or studying in class. And after using NEEP, students became more sensitive for noise environments than previous. And also students showed the positive attitude for solving noise troubles. It was meaningful in the level of p<.001 that the result of noise knowledge and awareness in the pre-post test within experiment group. However, all of the results in comparison group didn't represent statistically meaningful difference. And there were meaningful differences between experiment and comparison group after carrying out NEEP. In the area of noise knowledge and awareness, there were clearly meaningful results in the level of p<.001. Although the difference in noise attitude was a little, it was analyzed to have not a meaningful result. What suggested for researches in future are as follows. First, because until now the concrete research for the elementary student who exposed to noise and experienced a difficulty in hearing is deficient, many studies are needed. Second, NEEP with more lessons is required because the change of effective attitude needs long term. Third, due to the student who exposed to noise generally has low ability for concentration, NEEP compensated with activities is needed.

초등학교 4학년 수학은 도형 영역에서 다양한 개념들이 동시에 등장하는 시기로, 특히 삼각형이나 사각형 등과 같은 평면도형의 경우 그 개념이 총체적으로 학습되는 시기이다. 본 연구는 초등학교 4학년 학생들을 대상으로 그들이 학습한 도형 개념들에 대한 이해 정도를 파악하기 위해 '정의하기' 서술형 평가를 실시하고, 또한 그들이 갖고 있는 비형식적인 지식을 살펴보기 위한 '이름짓기'(naming) 서술형 평가를 실시하였다. 이를 통해 학생들이 이해하고 있는 도형의 개념정의와 개념이미지를 분석하고, 각각의 특징 및 반복해서 등장하는 오 개념과 그 원인을 분석하여 도형을 학습하고 지도하는 과정에서 생각해볼 유의점을 제안하고 있다. 더불어 학생들의 이름짓기 활동을 통해 도형의 어떤 요소에 가장 먼저 주목하는가를 분석함으로써 이 과정에서 그들이 인식하지 못하거나 빈도가 낮게 나타난 수학적 성질과 개념을 살펴보고 동시에 학교수학에서 도형 학습을 통해 갖게 되는 비형식적 지식을 고찰함으로써 도형 영역의 학습 지도를 위한 개선 방안을 제시하고 있다.
