Scientifically gifted students' argumentation characteristics in science instruction using the internet messenger was investigated. Participants in this study were five 9th grader in middle school in Seoul. They attended a program offered by the Science-Gifted Education Center, Seoul National University. Internet messenger (instant messenger) was used for instruction, and data were collected by saved messages. Toulmin's argument model was used as a tool for analyzing students' argumentation, and the argumentation patterns were categorized by sequence of argument operations. The results showed that in case of learner-centered instructions, there were lots of relatively higher-level argumentations appeared. On the contrary, teacher-centered instruction ended up with few or lower-level argumentation. Also there were four types of argumentation patterns emerged throughout the whole instructions. Findings suggest that the development of an instruction models and the selection of an appropriate topic be necessary for promoting the interaction between teacher and students as well as enhancing the students' ability of argument.

The purpose of this study is to examine the relationships between image of nurses and nursing professional values in nursing students. Data were collected through self reported structured questionnaire using convenient sampling methods survey from 147 students enrolled in the nursing department from March 11 to March 22, 2013. There was a significant difference in the image of nurses on the club activities, satisfaction with major, satisfaction with college life. There was a significant difference in the nursing professional values according to the satisfaction with major. Image of nurses has positively correlation with nursing professional values. 'Social participation' domain of image of nurses has a strong positive correlation with nursing professional values. 'Self concept of profession' domain of nursing professional values has a strong positive correlation with image of nurses. Therefore, it is thought that developing various teaching strategies, promoting club activities, paying attention to the student, and guiding them for raising degree of satisfaction with major and college life would be helpful to improve nurse' image and nursing professional values of nursing students.

With the increasing access to the internet, the number of designers who rely on internet to use information on design is on the rise. Therefore common dictionary of design terminology need to be formed and shared among designers. To do so, internet is very useful medium. However as relating terminology increases rapidly through interactivity among designers, it will be far from taking full advantage of features of internet to set up and provide such information unilaterally on internet. This indicates that providing data on the internet, not via traditional books, requires in-depth study on process of establishment of database structure and appropriate interface design. Thus this study will show design terms database model that harnesses internet feature that enables establishment of information spontaneously through user's interactivity, departing from a model that conveys information unilaterally. This report summarized and analyzed various models and suggested classification system in accordance with user's learning cognition. Problems on existing dictionary of design terminology were identified and new methods addressing such problems were exploited. In a word, this report is intended to propose user oriented inter-constructive database model that highlights high level of openness and interactivity by enabling changes of text in the cyber space and encouraging user to participate in making design dictionary.

Electronic BBS (bulletin board system) Ins been widely recognized as an appropriate medium for exchanging ideas and sharing information asynchronously. The communication ability if BBS is the main reason for utilizing it as a tool for collaborative learning. Researchers in the community reported a number if findings regarding the educational utilization if BBS recently. In this paper, we propose a qualitative method to measure communication activities using BBS so that the complex discussion behaviors of participants can be understood analytically. We propose characteristic vectors to describe discussion behaviors of groups and individuals, which can be conveniently used for characterizing and comparing discussion groups as well as individuals. The interactivity model representing interactive activities shows graphically the degree of inter activity if discussion groups as well as individuals. Also, time dependent measurements are investigated to analyze discussion activities with time. Experiments on the proposed measurements conducted on the Web-based discussion project using BBS demonstrate how measurements can be carried out, how characteristic vectors and inter activity model can be constructed and used.

The purpose of this study is to present the mental model of young adolescents' media environment and the use and to provide several educational suggestions drawing on the revealed model. For this, the data were collected through 4 activities such as interview, picture drawings, word association experiment, and sentence completion task with ten 4-5th graders in elementary schools; they were qualitatively analyzed by 2 researchers. First, the meaning components driven by sentence completion task, word association experiment were totally 6 components: media device, connection(alienation), competence(provision), entertainment, adverse effects, ambilaterality. Second, the components of media mental model driven by pictures were 4 components: functions/competence, entertainment, conflict with paper books/sharing, harmfulness/ambilaterality. Third, the components from interview consisted of conflict between paper books and electronic media, communication-centeredness, fear(addiction) and users' qualification. Based on those results, careful examination in cyber talk, necessity of addiction prevention, active development of learning media and their balanced utilization with books, and healthful media literacy education and reinforcement of critical thinking were suggested.

Inquiry instruction is a dynamic process that uses questioning and answering to have students actively participate in their own learning. Inquiry instruction is a teaching technique in which teachers do not provide knowledge, but help students discover knowledge by themselves. However, Inquiry instruction currently has problems of lack of connection between inquiry process and school library, lack of collaboration between the media specialist and teacher, and lack of applicable models. Information literacy is the ability to access, evaluate and use information. Information literacy process is closely related to the inquiry process. Thus, this study suggested an elaborative model in inquiry instruction using information literacy process. This research derived the skills, strategies, activities of inquiry instruction model by comparing and analyzing Lippitt's inquiry process with information literacy process(Big6 Skills, Pathways to Knowledge, I-Search, 8Ws, Inquiry Process, Inquiry in the Research Process). Based on the results, this study designed an elaborative model in inquiry instruction using information literacy process.

The purpose of this study is twofold: to theoretically review the 'resources-based view' (RBV) developed by D. Hammer and his colleagues as an alternative cognitive theory and to illustrate the usefulness of the theory by applying it to interpret a science learning activity in which undergraduate students worked together to construct a model of the seasons. The theoretical review was based on the exploration of relevant literature and dealt mainly with three types of resources: conceptual, epistemological, and practical resources. The trial application revealed that scientific models have been developed through the combination of different pieces of conceptual resources activated from participants, rather than emerging as unitary wholes. However, all the activated resources were not included into a model, and some of the conceptual resources acted as constraints to constructing a scientific model. The implications included that science educators should be attentive and responsive to students' resources and help them use the resources productively to learn science.

In this paper, we propose a gaze depth estimation method based on a binocular eye tracker for virtual reality and augmented reality applications. The proposed gaze depth estimation method collects a wide range information of each eye from the eye tracker such as the pupil center, gaze direction, inter pupil distance. It then builds gaze estimation models using Multilayer perceptron which infers gaze depth with respect to the eye tracking information. Finally, we evaluated the gaze depth estimation method with 13 participants in two ways: the performance based on their individual models and the performance based on the generalized model. Through the evaluation, we found that the proposed estimation method recognized gaze depth with 90.1% accuracy for 13 individual participants and with 89.7% accuracy for including all participants.
