In response to epoch-making development in science and technology, the innovative curricular materials have been begun to develop since the late 1950s and early 1960s. However, the new inquiry-centered materials have failed to be successfully used in teaching/learning practices of science. Among the various reasons for the failure, the very nature of the inquiry approach has been identified as the most critical problem. Nevertheless, fostering inquiry faculties on the part of the students has been emphasized as one of the most important objectives of science instruction. Therefore this study was conducted for the purpose of developing a practical inquiry-oriented instructional method. In order to obtain this goal the nature of scientific inquiry was analyzed and the status quo of science education in which inquiry-oriented instructional strategies were applied was examined. The results of the study are described in this paper.

This study investigated the condition of chemistry teacher's student competency assessment based on the inquiry report. To this end, an inquiry report was collected for chemistry teachers who took the training at two universities that conducted the 2020 first-class chemistry teacher training. The science subject competencies presented in NAEA analysis framework was used to analyze what kind of competencies teachers assess students through inquiry reports. A total of 63 chemistry teachers submitted inquiry reports, which were analyzed by competency, sub-element of each competency, and detail element to analyze the actual situation. As a result of the study, most chemistry teachers reflected their 'scientific inquiry and problem-solving ability' in their evaluation through inquiry reports. 'Ability to understand and apply scientific principles', which is mainly evaluated through paper-based evaluation, was partially used as confirmation of prerequisite learning at the beginning of the inquiry and the weight of evaluating 'scientific communication skill' was not large. In 'scientific inquiry and problem-solving ability' through inquiry report, 'design and conduct explorations', 'data analysis and interpretation' and 'drawing conclusion and suggesting solution' were mainly assessed. However, 'discover and recognize problems' and 'development and use of model' were hardly assessed.

In this study, the on-line discussion learning system of physics investigation was developed for developing the creativity in the problem solving and critical thinking. And with the number of participants of a topic unit, the formation of multiple discussion field and a turn-taking, we found that the interaction patterns of the students were composed of interpersonal interaction pattern, interaction pattern of one to one participation, interaction pattern of one to many participation and interaction pattern of many to many participation. These interaction patterns could make us understand the participation structure and the aspect of interaction of the students in the cyber space.

The purpose of this study was to find the effects of the science camp program on Science Process Skills and Scientific Attitudes for the Scientific Gifted Students. For this purpose, this research developed the science camp program. This program was totally consisted 30 lessens. there was 2 part in this program. It contained Astronomic Space Science(14 class), Aerospace Science(16 class). To find the effects of the science camp program on Science Process Skills and Scientific Attitudes for the Scientific Gifted Students. 20 participants was selected. these students were attended at a scientific gifted class(5th grade) of an elementary school located in Ulsan. First, Science Process Skills was used to find the effect of the science camp program And the results were analyzed by SPSSWIN 18.0. The results of this study were as follows. the science camp program was a positive effects on Science Process Skills of the Scientific Gifted Students(t=8.649, p=.000). Second, the science camp program was a positive effects on Scientific Attitudes of the Scientific Gifted Students(t=3.431, p=.003). According to this research, the science camp program on Science Process Skills and Scientific Attitudes for the Scientific Gifted Students. It will be contribute on the curriculum construction of the gifted school or gifted class.

The purposes of this study were to develop teaching strategy enhancing creative problem solving skills and to examine the instructional influences on studints' creative thinking skills, critical thinking skills, creative personality and academic self-regulation. In this study, a model using inter-disciplinary analogies(PDCA model) was designed and applied to the existing 'Teaching model for the enhancement of the creative problem solving skills'. And it was implemented to preservice science teachers for the one semester. Results indicated that the experimental group presented statistically meaningful improvement in creative thinking skills, especially in the originality of identifying a problem, making hypothesis, and controlling variables (p<.05). In addition, the strategy contributed to improving critical thinking skills, especially in inquiry process of recognizing problems, making hypothesis, interpreting and transforming of data (p<.05). This strategy also helped students' academic self-regulation (p<.05). But there was no significant improvement in creative personality(p<.05).

p 편광 레이저광이 금속 표면에 입사할 경우에 있어서, 금속 표면에 작용하는 법선방향 전기력을 입사각에 대한 함수로서 이론적으로 탐구하였다. 입사각이 90 도에 근접할수록 큰 값이 얻어지고, 그 방향은 금속 표면에 수직하게 밖으로 잡아당기는 방향임을 알아내었다.

최근 디지털화의 가속, 통신 인프라의 확충 등으로 전자, 정보 통신 기기들이 단일 네트워크로 연결되어 영상 및 음향정보를 서로 공유할 수 있는 환경이 마련되고 있다. 다시 말해 가정 내 모든 기기들이 네트워크화되어 마치 하나의 기기처럼 작동이 가능하게 되는 홈네트워킹의 구축이 가능해 지고 있는 것이다. 최근 LG경제 연구소에서 발행한 한 보고서에 의하면 홈네트워킹 관련 기술의 급속한 발전으로 새로운 사업 기회가 등장하고 있다. 이를 기회로 적극 활용하기 위해서는 국내 기업들의 기술력 제고, 전략적 제휴 확대 등을 통한 전반적인 경쟁력 강화가 시급하다고 지적하고 있다.

우리는 흔히 21C를 정보화 시대라고 하며 우리에게 주어지는 정보들 또한 일기예보와 같은 일상적인 분야에서 여론 조사와 같은 전문적인 분야에 이르기까지 아주 다양하다. 이런 정보들은 통계영역과 아주 밀접하며 이런 정보들을 통계적으로 바르게 해석하고 추론하여 일반화하는 등 일련의 과정들을 요구한다. 이런 상황아래 본 연구에서는 6차 초등학교 수학 교과서에서 여러 통계학 영역 중 그래프 형태로 가장 먼저 도입되는 막대그래프에 중점을 두어 현행 교과서에서 학습 내용과 학습 과정의 문제점에는 어떤 것이 있으며 아울러 그래프 이해력에 필요한 요소나 인지적 사고 능력, 그래프 이해력의 수준을 알아보고, 이를 바탕으로 여러 문헌을 통해 본 연구자가 나름대로 구안한 통계적 기법을 사용한 교수 ${\cdot}$ 학습 과정을 실험반에 적용한 후 그래프 이해력 사전 ${\cdot}$ 사후 검사를 비교함으로써 통계적 기법을 사용한 교수 ${\cdot}$ 학습 과정이 그래프 이해력에 어떠한 영향을 미치는지 알아보고자 한다.
