  • The purpose of this study is to investigate teacher's knowledge of concept of equality and derive implications about proper teaching methods. To solve these study problems, three elementary school teachers are chosen for this study, and a pencil-and paper tests for comprehension of the equality concept targeting 72 students for elementary school that the teachers are in charge of the students was carried out. Also, The semi-structured interview(using a questionnaire) was conducted for analyzing of the teachers' knowledge of the equality concept. The findings are as follows. First, during the lesson, the teachers' reading of equal sign has a decisive effect on the students' the way of reading. Second, teachers tend to interpret the concept of equality as a systematic analysis rather than a relational analysis, and use a equal sign focusing on meaning of 'same result'. So, Students also can't interpret the concept of equality as a relational analysis. Third, under the influence of teacher's feedback or reaction, making the mistake of the using equal sign of students reoccurred continually. Fourth, teachers misjudged some of examples of the nonstandard context equation for teaching elementary school students. Furthermore, during the lesson, they usually used a limited equality context. So, students can't have a chance to learn equality in a plenty of context. Thus, the knowledge of teachers and their lesson has decisive influence on the comprehension of students about the equality concept. So, Teacher has to focus on the meaning of the equality as a relational analysis and teach them in a plenty of context. With this, lots of study and in-service training are needed to enhance knowledge of teachers. And more of lesson programs and materials have to provided on the instruction manual for teaching the meaning of the equality.

  • Men learning has no fixed route. In other words, any route can be taken, which can also be seen in the structure of other "complex systems" discussed in modern society. It can also be examined through Yang's long-standing classic, The Book of Changes Men learning itself started from informal learning to become today's formal learning. As we look at the stages of human civilization's progress, we can quickly discover these stages of development. The issue of human beings has always been a topic of discussion, and these discussions are ongoing. Men learn through language and tools, technology and culture, and through philosophy, art, and religion to deal with their complex and diverse mental world. Through these various activities, learning is accomplished. This is not limited to the physical processes of one generation learning through inheriting knowledge; men's learning, a kind of mental process, has extended our life. This is why there is no other reason that men's minds and learning are always developing. This study is about how to learn in a complex and diversified modern society and to find out how to coexist with the principles of the "complex system" and The Book of Changes.

  • Software visualization can assist developers to understand a software system and change its code. The recent development of bottom-up visualization tools demonstrates the advantages by revealing the code that is directly related to a software evolution task. However, the information provided by these tools is limited to the code already investigated by the developers in that task session. To broaden the scope and provide the code information that developers should explore, we propose to present the latest revision of a software system via a class diagram. When a developer clicks on a button, the proposed tool reveals the code changes committed to a configuration management system, and facilitates the understanding of code changes. We also conduct case studies illustrating the advantages of the proposed tool.

  • This paper determined students' ranks of difficulty on the use of materials in terms of 1) understanding the layout of the learning materials, 2) reading comprehension of the learning materials, and 3) realization on relevance to needs of the learning materials. It also determined students' 4) rank and frequency of attitude on the materials. With the data gathered through 128 survey questionnaires, 7 focused group discussions, and 10 interviews, the results were found out that there was an inappropriate assessment procedure set by this particular university. The researcher concludes that: 1) design of four types of classes by just using the two textbooks with their respective workbooks is grammar-based with limited conversation activities; 2) placement for these students in one big class size was implemented without considering their common interest and motivation and language levels; and, 3) qualification of teachers teaching these EFL students did not support students' real needs and the language program itself. Content professors who were made to teach may have the ability to input learning, but their teaching styles may differ from the ones who are real English teachers. This paper then recommends that teachers and school administration should have an appropriate placement exam before students attend the class, especially in a big class size. There could only be a few problems among students in one big class size when students' level of competence is proportioned. With this, topics and conversation activities can even be more flexible with the maneuver of art of questioning, various dimensions of thinking, strategic competence, learning attitude or behavior, etc. to ensure sustenance of communicative mode and level of interest and motivation in the classroom. Grammar-based instruction can only be taught when a need arises. Thus, the course description of each class will be able to transact the objectives ready for developing students' communication competence. Moreover, proper measurement can be utilized to validly assess the amount of students' learning and the progress of language curriculum design in terms of materials selection and teaching approach.

  • The ambiguity of spatial language can be a source of communication problems. For instance, the 'the opposite side' in a sentence such as 'where is the opposite side of building X' can mean more than one direction. Research interests are focused on the directions of a spatial language 'the opposite side'. This study also explored the effect of geometric properties such as reference object's shape and distance from the reference object and spatial reference frame in the comprehension of 'the opposite side'. The assessment tasks used consisted of rating how appropriate the sentence 'where is the opposite side of building X' was to describe a series of pictures. The results of experiment suggest that 'the opposite side' means in most cases more than one direction simultaneously. Changing spatial reference frame has significant effects on individuals' rating of the tasks. However, while reference object's shape (prolonged building) has a consistent effect of the ratings given, the distance from the reference object (shortened road width) has limited influence in comprehending the tasks.

  • This study was conducted to compare the outward aspects, objectives, and the contents of Home Economics text books of middle schools of Korea, Japan, U.S.A. and England. The results were summarized as follows. 1. The outward aspects of tex books: The Korean text books were small in size and the quality of paper was inferior to those of foreign countries. The Japanese text books were written by many authors, contained many lab works and data. Text books of U.S.A. were big in size made with good quality paper and contained many colour pictures. Text books England contained many problems and lab works. 2. Objectives of the Home Economics and Unit objectives: The objective of the subjects of Home Economics was written only in Korean text books. The unit objectives were described most concretely and detailedly in Korean text books comparing with other countries. 3. Contents: Korean text books covered all six areas of foods, clothings, housing, home management, family and occupation and theoretical explanations prevailed. Japanese text books contained numerous lab works, lacked two areas of home management and occupation, thecontents included a few practical lab works two areas of home management and occupation, the contents included a few practical lab works. In the text books of U.S.A. contained all six areas of Home Economics were covered and special emphasis was placed on self discovory and self development, and vocational guidance was also stressed. The text book of England contained only three areas of Home Economics, clothing, foods and housing; the number of area was limited but the basic theories of covered area was intended to lead to self comprehension through questions and lab works.

  • Carlos Jimenez's 'House and Studio' was self-designed to fully function as both a home and workplace. Since its establishment in 1983, the installation has been continuously updated for almost 30 years solely under the guidance of the owner's life occurrences and routine needs. The additions and alterations succeeding the building's erection were executed to incorporate small yet symbolic fragments of the resident's memories and life episodes. The particularity of the 'House and Studio' can be compared with other residential remodeling and expansion projects in regards to certain key aspects. These means of comparison include, but are not limited to, building strictly under the direction of a master plan of development vs. allowing natural adaptations that comply with the resident's needs, rapid development vs. gradual advancement, the ornamenting by exposing showy features vs. the enhancing by addition of modest natural components, sustainability vs. sustenance, systematic room divisions vs. ambiguous spatial organization, possession as a materialized asset vs. preservation as a recollection of memories, and finally the recognition as one example of signature architecture vs. the witnessing of a maturing animated shelter. The given propositions can be further explained with the comprehension of Erich Fromm's theory of the 'Having' mode and 'Being' mode, two mechanisms that categorize the essence of human life. The 'Having' mode is described by the human greed for wealth, power, and influence, whereas the 'Being' mode is comprised of compassion, joy, and productivity. Fromm's thesis applies to the general sense of human life, but the ideas can be narrowed to accommodate the architectural standpoint. In architecture, the 'Having' mode can be translated to be the conspicuous form-oriented and self-contained object. The 'Being' mode, on the other hand, is transposed as the more natural form, incorporating the needs of the owner before commercialization. The growth of Jimenez's 'House and Studio' can be perceived as an architectural suggestion to the overcoming of human indifference caused by fixation on the 'Having' mode.

  • This study shows the current management status and the results of B University's multicultural creative-HR team's voice training supporters' preparation course that is part of the local funding project at the university. For this, the concept of voice training and educational contents of the multicultural members are first extracted from several documents. Then, a description of the management case of B University's voice training supporters' education course is given regarding the goals, operator of management, propulsion progress, and contents of previous education. For analyzing the management results of this work, in-depth interviews with the supporters and a half-structured survey are conducted with the voice academy main instructors. Moreover, reports of the work results, work journals of supporters and etc. are used for analyzing the results. According to the results of this analysis, the aspect of education, previous education contents, and teaching practicum are not organically connected. A more detailed curriculum about the comprehension ability of practical affairs is needed for managing a classroom. In aspect of management, the preparatory stage of voice training course and the practice stage were not linked, and thus, more cooperation is required with the main instructors. Although the results are limited, the voice training of the supporters' training course has its implications. First, the education of Korean pronunciation and intonation are provided for the supporters, thereby being able to facilitate learner-centered education. Second, it demonstrates in an empirical case that a class can be administered by specializing in Korean pronunciation and intonation. At last, it can provide a chance to practice teaching and offer field experience for students who have a Korean education major.

  • With the advent of smart media, short and fast-paced video content appeared, and conditions for viewing changed to viewing in environments where the perception is dispersed due to distracting and complicated external situations in a short period of time. Accordingly, smart media videos are quickly delivering meaning while keeping the eyes of viewers who lack patience. Our eyes and brain have a hard time accepting image information that flows through the constraints of a small screen. Our visual perception is limited in terms of acceptable visual information and, in particular, less cognition in moving images, so the production of smart media images should be directed in a way that enhances perceptual understanding. To be able to effectively communicate what you want to talk about while reducing the visual burden, intuitive image comprehension is needed by applying intuitiveness and behavioral induction to the moving images. Close-up shot, stable structure such as frontality and three-division structure, and color have such 'visual affordance' Therefore we need to use that device appropriately.

  • Object orientation has become the predominant paradigm for conceptual modeling (e.g., UML), where the notions of class and object form the primitive building blocks of thought. Classes act as templates for objects that have attributes and methods (actions). The modeled systems are not even necessarily software systems: They can be human and artificial systems of many different kinds (e.g., teaching and learning systems). The UML class diagram is described as a central component of model-driven software development. It is the most common diagram in object-oriented models and used to model the static design view of a system. Objects both carry data and execute actions. According to some authorities in modeling, a certain degree of difficulty exists in understanding the semantics of these notions in UML class diagrams. Some researchers claim class diagrams have limited use for conceptual analysis and that they are best used for logical design. Performing conceptual analysis should not concern the ways facts are grouped into structures. Whether a fact will end up in the design as an attribute is not a conceptual issue. UML leads to drilling down into physical design details (e.g., private/public attributes, encapsulated operations, and navigating direction of an association). This paper is a venture to further the understanding of object-orientated concepts as exemplified in UML with the aim of developing a broad comprehension of conceptual modeling fundamentals. Thinging machine (TM) modeling is a new modeling language employed in such an undertaking. TM modeling interlaces structure (components) and actionality where actions infiltrate the attributes as much as the classes. Although space limitations affect some aspects of the class diagram, the concluding assessment of this study reveals the class description is a kind of shorthand for a richer sematic TM construct.
