본 논문은 옛 궁궐 또는 민속마을과 같이, 어떠한 사건 또는 상황과 관계 있는 문화관광지를 관광하는데 있어서 몰입적 체험관광 시스템이 갖는 효용성을 탐구한다. 현재까지 대부분의 국내 문화관광지는 정적이고 정보전달 중심인 고전적 관람 형태를 유지하고 있다. 이는 관광 형태가 새로운 경험을 추구하는 방향으로 변화하고 문화 관광산업의 규모와 중요성이 커져가는 추세에서 해결해야 할 과제로 부각되고 있다. 본 연구에서는 이를 개선하기 위한 일환으로 몰입적 체험관광 개념을 탐구하였다. 몰입적 체험관광이란, 유적지 및 사적지 유형의 관광지에서 관련된 실황을 마치 시간여행을 하듯 생생하게 체험하는 관광 방식을 의미한다. 본 개념을 실현하기 위해 증강현실 기술을 활용하였으며 문화관광지에 적용할 수 있는 시스템을 고안하였다. 이 시스템은 한 장소에 고정되는 포스트 형태로 시청각적 증강현실을 구현하여 몰입적 체험 관광을 제공한다. 실제 유적지에서 일반관람객들을 대상으로 시청각적 증강현실 체험을 실험한 결과, 흥미와 현장감이 향상됨과 동시에 컨텐츠에 대한 이해도 또한 향상되는 것을 확인할 수 있었다. 이러한 연구 과정을 통해 유적지 및 사적지 유형의 문화관광지에서 관광의 질을 높일 수 있는 몰입적 체험관광의 효과와 가능성을 확인할 수 있었다. 더 나아가, 본 연구는 기술의 새로운 적용 방법을 통해 새로운 경험을 창출하는 측면에서 의의를 갖는다.

The purpose of this study is to examine how online knowledge-based search service is being used by students in science education. Reviewing information and summarizing data are important parts in scientific inquiry. As more and more information is available online, how to review and summarize online information for scientific inquiry also becomes an issue. In this study, we examined one of the popular online knowledge-based search services to see what kinds of information in secondary school chemistry are mostly sought and how reliable those information could be. The result indicated that users mostly seek scientific explanations and problem solving but about 30% of provided information appeared to be incorrect. It implicates that it is necessary to pay attention for teaching students how to obtain, evaluate, and communicate online information in science education to enhance students' ability for scientific inquiry.

In this study, we developed analogical experimental activities to foster scientific creativity in inquiry learning and applied them to 7th grade science-gifted students. The influences of inquiry learning-based analogical experiments were investigated with respect to the experimental design processes. We classified the patterns of experimental design processes by creative thinking processes and analyzed performance levels by the elements of experimental design processes. The students' experimental design processes were categorized into three kinds of patterns such as reinitiated motion, backward-divergent motion and stationary motion. Those belonging to the reinitiated motion performed precise experimental design from new perspectives by identifying the mapping in depth and considering the elements of experimental design processes. In the case of the backward-divergent motion, they shifted their positions to new directions, but the concreteness of experimental design was insufficient due to the lack of mapping or considering the elements. In the type of stationary motion, maintaining their previous positions, they showed less performance of experimental design without considering the elements sufficiently. Educational implication of these findings are discussed.

The purpose of this study was to search for effective strategies on teaching open-inquiry by comparing students' and teachers' recognition of its difficulties and helpful strategies. This study focused on the cases of science high school students and their teachers, who carried out open-inquiry to participate in KYPT. This research was conducted through participant observation, questionnaires, and interviews. The research findings were as follows: students stated that planning and doing experiments were the most difficult parts, whereas teachers viewed that their students had difficulties in analyzing data and making a conclusion. With respect to the effective strategy, students stated that they gained many ideas from peer discussions although they have had to carry out their individual tasks. On the contrary, teachers thought that reference materials and the discussions with teachers were most helpful. There were clear differences between students' and their teachers' recognition toward open-inquiry and the gap needs to be closed. Consequently, it would be useful to guide students to form teams and to spend more time in peer discussions especially when doing experiments and to encourage teachers to understand students' actual difficulties and needs.

The purpose of this study is to examine the characteristics of model of the experiment in students' open inquiry. The research is a reinterpretation of the data collected from the performance of a three-year research project under the theme of 'school science inquiry' the perspective of model of the experiment. The inquiry activities of a focus group made up of four students have been recorded seven times. The recorded files and transcribed copies were analyzed according to interpretive methods. Students' activities were divided into three modeling of the experiment units, considering the modeling unit that includes the process of starting from the problem until it gets solved. The results of the study include illuminating the dynamic process and characteristics of modeling of the experiment and discussing its educational meaning as a distributed cognitive system at each modeling unit. First, students, instruments, and the primitive form of calculation represented by the interaction between them turned out to be important factors in the distributed cognitive system that constitutes model of the experiment. Second, in the early stages, non-verbal activities were carried out in which students became familiar with instruments, and verbal quantitative signs were created when the activities were sufficiently carried out. The generated quantitative signs became a source of data and confidence that can be referenced in subsequent activities. Third, the specialization of instrumentalization occurred, and factors that were important in inquiry, such as variable control, appeared. The results of the study provide new implications for science education research and education, which have been centered on explanatory models, by unfolding the characteristics of model of the experiment that have not been noticed in science education through students' inquiry.
