  • The purpose of this qualitative case study was to investigate the 'structure' of an elementary school teacher's practical knowledge concerning science experiment lessons. A female elementary teacher in the early career years participated in the study, and video recordings of her science experiment lessons as well as audio-taped interviews with her were analyzed by means of Elbaz's framework. The teacher expressed six images of science experiment lessons: 'Science is difficult', 'Experiments are dangerous', 'Experiments are accurate', 'A science experiment takes a long time', 'Science experiments are interesting', and 'Children are little scientists.' These images were supported by several principles and rules, most of which were clearly described. Among the images, principles, and rules, there were complex relationships with some working in synergy and some conflicting. In case of the image 'Children are little scientists', its subordinate principles and rules were not fully realized in the classroom. Implications for science teaching reform and science education research were discussed.

  • In this paper I will discuss definitions of hypermedia, multimedia and hypertext. Hypertext is the grouping of relevant information in the form of nodes. These nodes are then connected together through links. In the case of hypertext the nodes contain text or graphics. Multimedia is the combining of different media types for example sound, animation, text, graphics and video for the presentation of information by making use of computers. Hypermedia can be viewed as an extension of hypertext and multimedia. It is based on the concept of hypertext that uses nodes and links in the structuring of information in the system. In this case the nodes consist of an the different data types that are mentioned in the multimedia definition above. The 'node-and-link' concept is used in organisation of the information in hypermedia systems. The 'book' metaphor is an example of the way these systems are implemented. This concept is explained and a few advantages and disadvantages of making use of hypermedia systems are discussed. A new approach for the development of hypermedia systems, namely the knowledge-based approach is now looked into. Joel Peing-Ling Loo proposed this approach because he thought that it is the most effective way for handling this kind of technology. A semantic-based hypermedia model is developed in this approach to formulate solutions for the restrictions in presenting information authoring, maintenance and retrieval. The knowledge-based presentation of information includes the use of conventional data structures. These data structures make use of frames(objects), slots and the inheritance theory that is also used in expert systems. Relations develop between the different objects as these objects are included in the database. Relations can also exist between frames by means of attributes that belong to the frames.

  • Perception of the experiment is one of the most important factors of students' understanding of scientific inquiry and the nature of science. This study examined the perception of middle and high school students of the meaning of 'experiment' in the biological sciences. Semantic network analysis (SNA) was especially used to visualize students' perception structure in this study. One hundred and ninety middle school students and 200 high school students participated in this study. Students responded to two questions on the meaning of 'experiment' in science and biology. This study constructed four semantic networks based on the collected response. As a result, middle school students about the 'experiment' in science are 'we', 'direct', 'principle' of such words was aware of the experiments from the center to the active side. The high school students' 'theory', 'true', 'information' were recognized as an experiment that explores the process of creating a knowledge center including the word. In addition, middle school students relative to 'experiment' of the creature around the 'dissection', 'body', high school students were recognized as 'life', 'observation' observation activities dealing with the living organisms and recognized as a core. The results of this study will be used as important evidence in the future to map out an experiment in biological science curriculum.

  • This study aims to design a framework for analyzing group argumentation in terms of participants' interaction. Regarding the current group argumentation setting as argumentation on socio-scientific issues within participants who have had limited experience on group argumentation, the analytical framework was designed to explain (1) what was each participant's role on group argumentation, (2) how these roles were changed within each time of argumentation, and (3) how the patterns of interaction were changed through seven times of a series of argumentation on socio-scientific issues. Based on the literature review on analytical framework of argumentation in science education including the works on the structure of argumentation, the discourse formation through interaction, and the linguistic approach on participants' interaction, the current research framework was built. Showing the results of applying the designed framework on group argumentation as an example, strength of using the current designed framework was discussed.

  • Information gathered through experience transforms into knowledge and such knowledge becomes a foundation for intuitive decisions. Based on such background, the following study investigates intuitive decision making on basic elements needed for design concepts and visual conceptualizations. The study consist two phases. first, 12 structural elements of a digital camera and relation between each elements were arranged intuitively on a board. Next, sketches were generated with relationship of structural elements in mind. As a result of the study, concept with intuitive decisions effect structural thinking, various developments, specific operation methods , and sketch expressions. However, study also revealed that the freedom of human emotions don't accord with the qualification map.

  • Information Technology Service Management (ITSM) System has been adopted and operated by many governments and public institutions to intensify their global competitiveness. Recently these organizations are facing many problems because of the increased demands and complexity of Information Technology (IT) service. Especially, difficulty with ITSM gets bigger and bigger because of increasing IT outsourcing. An expectation regarding ITSM is grown up when facing to solve problems. Therefore, this study suggests effective alternatives about ITSM organization structure for public sectors. The ITSM organization structures changes from traditional structures based on functions to new structures based on its goal, customer, and its process. In other words, ITSM organizational structure can be composed of Service Strategy directorate, Service Design directorate, Service Transition directorate, Service Operation directorate, and Service Improvement directorate. To ensure the effectiveness and the professionalism of ITSM in an organization, this paper specifies the roles of participants and the responsibilities for each unit. The proposed ITSM organization structures will be useful for public sectors.

  • This study proposes a theory of consumer experiences based on a cognitive science framework that serves as an alternative to the mainstream marketing paradigm of information processing and choice. The theory consists of three key theoretical constructs: experiential modules, primary vs. secondary experiences, and the hierarchy of experiential modules. Based on this theory, this study investigates the effect of experiential attributes and functional attributes on consumer's product evaluations, and the moderating role of consumer's knowledge. The main research findings are (1) the subjects react faster to sensory and affective stimuli(ex: experiential attributes) than they do to intellectual stimuli (ex: functional attributes), (2) the interaction modularity of attributes(functional vs. experiential) $\times$ tempo(normal vs. fast) $\times$ product knowledge(novice vs. expert) appear significantly with product evaluation as the dependent measure.
