In this study, elementary school teachers' needs for the website providing science instructional materials were examined. The participants were 151 elementary school teachers. The test for needs analysis consisted of fifty-three Likert-type items; 24 items for the content of website category and 29 items for the design of website category. Variables about participants' characteristics such as teaching career, the capability of using computers, and the frequencies of searching websites in obtaining science instructional materials were also examined. The results indicated that teachers' needs for the content of website category were significantly higher than those for the design of website category. Teachers' needs were relatively higher in the items concerning flawless materials, consistency of materials with science curriculum and/or learning objectives, information about target grade and/or related topics, free website, and the materials capable of immediate use in the content of website category. The items concerning the stability of website, the accuracy of links, providing easy and reliable searching methods, easy and fast downloading, and providing list of loaded materials showed relatively higher needs in the design of website category. In several items, teachers' needs were also changed with their individual characteristics.

The purpose of this research is to suggest a model or method of needs analysis for designing syllabuses. As the learner-centered approach in teaching and learning methods becomes general, the learners' needs or wants should be reflected on the syllabus design. However, standardized scores in the previous research have disadvantages to be distorted in data interpretations because the difference between the maximum value and minimum value is so big compared to the Likert 5 scales. To solve this disadvantage, the Max-Min method is used in the needs analysis for the syllabus design. So, the differences are presented. Needs analyses need to be selected variously according to situations. Thus, further researches are needed to develop several new methods as well as the Max-Min method or the standardized score method for the whole needs analyses.

In this study, we investigated teachers' experiences in teaching with the science museum as well as their confidence, their perceptions, educational needs, and their willingness to practice the instructions using science museum. A survey was administered to 225 elementary and secondary school teachers. The analyses of the results revealed that few teachers had training for the instructions using the science museum and not many teachers had experience in teaching with the science museum. Many teachers were also found to have low confidence in teaching with the science museum. Although the teachers had a relatively good understanding of the educational effects, nature and teaching strategies for the instructions using the science museum, they tended to apply the formal views on science teaching/learning to learning with the science museum. The levels of willingness to use the science museum in their instructions and educational needs of the instructions using the science museum were high. They wanted the information about practical aspects to use in the instructions using science museum most. Educational implications of these findings are discussed.

The purpose of this study is to explore improvable proposal of instruction through analyzing learners' needs and satisfaction for college of engineering. Based on the online survey date with undergraduate students in Seoul National University, recognition difference between students in college of engineering and all students in SNU was identified. Among several factors influenced on learners' satisfaction in class, it is shown that satisfaction to facilities is higher than any other factor related to instruction. Generally, satisfaction with teaching in class is lower while satisfaction to an extrinsic support to students is high. Therefore, instructors should be more concerned about teaching in class. Learners' satisfaction with instructors' feedback to assignments and tests is significantly higher in college of engineering. However, learners' satisfaction with the progress of classwork and assignment students should perform regularly is lower than one in other colleges.

The purpose of this study is to clarify the actual condition of the layout and floor planning of elementary schools for the 7th education curriculum. This article discuses about the basic characteristics of the plan composition and the outdoor spaces of 35 elementary schools in Gyeongnam prefecture. The results of this study are summarized as follows; 1) To respond to the 7th educational curriculum, unit classrooms need to be expanded or space for a multi-purpose room needs to be secured to serve the following purposes: the operation of educational program by the level and offering of unified Subjects. overall, elementary schools need to seek ways to deal with problems associated with space composition, types of classrooms, and changes in the number of classrooms so that the 7th Educational curriculum can be carried out smoothly. 2) Different from the past, various plan types are available nowadays. Even in case of schools with the same class size, their areas were different by 130 percentages or higher. Therefore, practicality needs to be more focused than facility standards in order for the school to cope with changes in future educational environment. 3) When designing the elementary school in the future, more space needs to be assigned for learning by expanding facilities - special purpose classrooms and supporting facilities - to accommodate students' various learning activities. In addition, faculty facilities need to be rearranged to promote research and development as well as to ensure the operation of the educational program. And, resident facilities that consider the close connection with the local community need to be rearranged in an efficient manner as well.

Recently, the roof garden of the large commercial facilities has been changed as a complex cultural space follow the users' diverse needs. It is focused on large commercial facilities on Seoul and Gyeonggi area but large commercial facilities of the province still has not been able to respond to the needs of users. Thus, the present condition of roof gardens was compared space components with physical environmental factors in Seoul, Gyeonggi and Daejeon, Chungcheong. Throughout the comparison, roof gardens in Daejeon and Chungcheong area were focused on finding ways to improve As a result, roof gardens in Seoul and Gyeonggi area were applied to a variety of factors in space components experience, learning, performance, exhibition and etc. It is composed to take place of various acts in the roof garden. On the other hand, roof gardens in Daejeon and Chungcheong were not applied a variety space components by comparing Seoul and Gyeonggi area. Physical environmental factors also were insufficient by comparing Seoul and Gyeonggi area the landscape, awning facilities, amenities for handicapped. As described above, space components and physical environmental factors in Daejeon and Chungcheong area roof gardens were insufficient. To perform the role of the roof garden changing as a complex cultural space and to confront to the users' needs space component such as learning, performance, exhibition should be considered during planning. And physical environmental factors supportable space components should be considered together.

The information overload with many information resources is an inevitable problem in modern electronic life. It is more difficult to search some information with user's information needs from an uncontrolled flood of many digital information resources, such as the internet which has been rapidly increased. So, many information retrieval systems have been researched and appeared. In text retrieval systems, they have met with user's information needs. While, in image retrieval systems, they have not properly dealt with user's information needs. In this paper, for resolving this problem, we proposed the intelligent user interface for image retrieval. It is based on HCOS(Human-Computer Symmetry) model which is a layed interaction model between a human and computer. Its' methodology is employed to reduce user's information overhead and semantic gap between user and systems. It is implemented with machine learning algorithms, decision tree and backpropagation neural network, for user adaptation capabilities of intelligent image retrieval system(IIRS).

Unlike behaviors that are generally known, information regarding unspecific behaviors is insufficient. For an education or guidance regarding the unspecific behaviors, collection and management of data regarding the unspecific behaviors of special-needs students are needed. In this paper, a consultation management model based on behavior classification of special-needs students using machine learning is proposed. It collects data by photographing the behavior of special students in real time, analyzes the behavior pattern, composes a data set, and trains it in the suggestion system. It is possible to improve the accuracy by comparing the behavior of special students photographed later into the suggestion system and analyzing the results by comparing it with the existing data again. The test has been performed by arbitrarily applying unspecific behaviors that are not stored in the database, and the forecast model has accurately classified and grouped the input data. Also, it has been verified that it is possible to accurately distinguish and classify the behaviors through the feature data of the behaviors even if there are some errors in the input process.

In order to truly integrate e-Learning system into regular curriculum at a university, mobile access to Learning Management Systems has to be enabled. Mobile devices have the potential to be integrated into the classroom, because they contain unique characteristics such as portability, social interactivity, context sensitivity, connectivity and individuality. Adoption of Learning Management Systems by students is still on the low rate, mostly because of poor usability of existing e-Learning systems. Our initial research has confirmed this hypothesis. Usability issue is rising to the higher level on the mobile platform, because of the mobile devices' limited screen size, input interfaces and bandwidth, and also because of the context of use. Our second hypothesis was that it is wrong to consider a mobile device as a surrogate for desktop or laptop personal computer (PC). By just adopting the existing Learning Management System on mobile devices with adaptive technologies such as Google proxy, we do not acquire the satisfactory results. Usability can prove to be even lower compared to desktop application. One possible solution to the problem could be development of rich client applications for today's mobile devices that would raise the usability to a higher level. We developed a PocketPC prototype application by using user-centered design principles, which we presented as a third alternative in usability research conducted among university students. Results gathered in such a way have confirmed that development of e-Learning system, in order to be widely accepted by students, needs to have the user(student) in the center of development process.

The purpose of this paper is to analyze teaching-learning program which can be applied to mathematically gifted students in primary school, Our program is based on constructivist views on teaching and learning of mathematics. Mainly, we study the algorithmic thinking of mathematically gifted students in primary school in connection with the network problems; Eulerian graph problem, the minimum connector problem, and the shortest path problem, The above 3-subjects are not familiar with primary school mathematics, so that we adapt teaching-learning model based on the social constructivism. To achieve the purpose of this study, seventeen students in primary school participated in the study, and video type(observation) and student's mathematical note were used for collecting data while the students studied. The results of our study were summarized as follows: First, network problems based on teaching-learning model of constructivist views help students learn the algorithmic thinking. Second, the teaching-learning model based on constructivist views gives an opportunity of various mathematical thinking experience. Finally, the teaching-learning model based on constructivist views needs more the ability of teacher's research and the time of teaching for students than an ordinary teaching-learning model.
