상호작용적인 가상현실 기술은 실제 환경의 제약을 극복할 수 있으며 사용자에게 흥미와 적극적인 참여를 유도하여 과학적 탐구학습에도 적극 활용되고 있다. 그러나 기존 연구에서는 주로 특정 교안에 대한 응용 프로그램의 개발에 중점을 두고 있어서 다른 교안을 위한 탐구학습가상환경 개발에 쉽게 활용하기 어려웠다. 이에 본 연구에서는 과학적 탐구학습 가상환경의 개발을 도와주는 통합적인 가상현실 시스템 SASILE (System for Augmenting Scientific Inquiry Learning Environments)을 개발하였다. 본 논문에서는 먼저 가상현실을 활용한 과학적 탐구학습 관련 연구를 살펴보고, 제안하는 시스템의 구조와 구현에 대해서 설명한다. 그리고 이 시스템을 이용하여 가상현실 모양성에서 한옥에 나타난 대류현상에 대한 과학적 탐구학습 환경 개발 사례와 가상환경 화성 암석의 성분을 측정하여 운석이 떨어진 곳을 찾는 화성 탐사 개발사례를 설명한다. 마지막으로 이 시스템의 향후 연구 방향에 대해 논한다.

This study analyzed variations of learning stress by comparing the salivary cortisol levels of students who participated in Earth Science inquiry activities. The cortisol concentrations between the pre- and post-inquiries of the sample of 34 university students, who had taken the course of 'Basic Earth Science and Experiments', were analyzed. The Earth Science inquiries consisted of geology and astronomy activities. The observational geology activities consisted of a session of 'structure contours and map patterns' and the cognitive astronomy activities consisted of a session of 'representations of horizontal and equatorial coordinates'. These Earth Science inquiry activities were found to cause students to have anxiety, and the thought processes that these activities involved were found to cause learning stress. The variations in cortisol concentrations of students increased by $1.6{\pm}5.9ng\;mL^{-1}$ after conducting observational activities in geology compared with $2.1{\pm}6.2ng\;mL^{-1}$ after doing cognitive activities in astronomy. The analysis of the observational activities in the geology inquiry activities indicated that they were consistent with low levels of learning stress. Conversely, the analysis of the cognitive activities in the astronomy inquiry activities showed significant individual variations in cortisol concentrations. Furthermore, individual differences in cognitive ability were reflected in the astronomy inquiry activities. While students, who received high scores, exhibited low levels of stress in the geology inquiry activities, they showed high levels of stress in the astronomy inquiry activities. It was concluded that, in the case of students with high scores in the study, the level of learning stress increased due to the raised anxiety in cognitive inquiry activities. In contrast, students, who received low scores in the study, exhibited high levels of stress in the geology inquiry activities, and low levels of stress in the astronomy inquiry activities.

The purpose of this study is to examine the effects of an free inquiry method based on PBL(Problem-Based Learning: PBL) to improve students science process skills and self-directed learning characteristics. To verify this research, twenty-two third-grade students were selected from Chung-ryeol Elementary School located in Busan. They have received pre-test and post-test about their abilities in their science process skills and abilities for self-directed learning characteristics. Also, their self-reflection data was analyzed. The teaching and learning PBL process is to provide the information named 'I am the expert on Earth and Moon' which is recreated by analyzing the science curriculum and characteristics of students from Lesson 3 'Earth and Moon', and to make plans for solving the information with K/NK method. Then, to solve the information is gathered and investigated using the PBL workbook. Lastly, students present their finding using the free inquiry method in a group. The post-test showed following results : first, the free inquiry method based on PBL stimulates inquisitiveness in students about science learning and the research group shows improved science process skill. It shows us that using the free inquiry method based on PBL can be used effects to elevate science process skill. Second, the free inquiry method based on PBL has a positive effect on self-directed learning. The research tells us that using the free inquiry method based on PBL can improve a student self-directed learning characteristics.

The purpose for this study is to check if research activities can make positive effects on inquiry instruction utilizing materials when compared to traditional instruction utilizing the textbook. The effects of the class should be measured both in cognitive domain and in affective domain. The cognitive domain was measured by the change in achievements in learning science, and the affective domain was measured by the change in learning attitudes of science. The assumptions to be verified in this study were as follows. First, achievements in learning science are higher in the learner oriented inquiry instruction utilizing materials than in the learner oriented traditional instruction utilizing the textbook. Second, learning attitudes of science are higher in the learner oriented inquiry instruction utilizing materials than in the learner oriented traditional instruction utilizing the textbook.The results of the research are as follows. In the cognitive domain, achievements in learning science showed significant change(p=.045) measured by verifying the score for the difference among the averages for each sub-scale, in 5% of meaningful probability, and were higher in the inquiry instruction utilizing materials study. In the affective domain, learning attitudes of science showed significant change(p=.019) measured by verifying the score for the difference among the averages for each sub-scale, in 5% of meaningful probability, and were higher in the inquiry instruction utilizing materials study. In learning attitudes of science, 2 items(self-conception of science, attitudes of learning science) out of 3 items(self-conception of science, attitudes of learning science, learning habits of science) showed significant changes (p=.045, p=.001). But the difference(learning-habits of science) was not significant(p=.914).

The purpose of this study is to device the teaching-learning method and the evaluating method on 'free inquiry' which is newly introduced in 2007 revised curriculum. The teaching-learning models which apply 'free inquiry' are 'group investigation', 'PBL', 'project investigation' and 'IIM'. And the unit which apply 'free inquiry' on the fourth grade and the second semester in the elementary science. The results of this study are as follows: First, The person leading the lesson is not a teacher but learners. The focus of teaching-learning is not a unit but topic, problem or project on the science textbook. A teacher's role is not the deliverer of knowledge but the guide of learning. Second, the outcome of applying group investigation, PBL project investigation and IIM to 'free inquiry' is improvements of the problem-solving ability and the self-directed learning ability as well as building scientific attitude and social skills as educational effect in commonly. Third, to apply 'free inquiry' efficiently, teachers should understand each subject very well, teach a class with a thorough and concrete plan, and try to evaluate objectively.

The purpose of this study was to examine the effect of integrated science inquiry teaming method through literature materials on the learner's science concept formation, inquiry ability, and attitude related to science when it was applied to the unit 'The temperature of atmosphere and winds', 'The journey of water' in the 5th grade, and to find out the effect on science learning according to teaming styles. To study these subjects, 4 classes of 5th grade in J elementary school in Busan were selected. The result of this study were as follows: First, Integrated science inquiry learning method through literature materials was more effective for concept formation than conventional teaching method. In science inquiry ability, there was not significant difference at all between the comparison group and the experimental group. In attitude related to science, the experimental group showed significant difference only in the interest in occupation related to science. The visual modality learners within the experimental group showed significantly higher statistics than the other modality learners in the post-investigation into the science concept and there was significant difference between the visual and the kinesthetic modality learners in the result of post-test on science inquiry ability.
