The purpose of this study is to compare the preferences of the school mathematical terms of South Korea and those of North Korea by administering a survey for learners, inservice teachers, and pre-service teachers, to establish the criteria of desirable school mathematical terms, and to evaluate the school mathematical terms of South Korea and those of North Korea based on the criteria. According to the result of the survey, the preferred mathematical terms are different from one group to the other, yet the mathematical terms of South Korea are more preferred. In general, terms written in pure Korean and concise terms which are easily understandable are favored. To discuss about the criteria of desirable school mathematical terms, four perspectives were set up, 1) the semantic perspective and the regulatory perspective, 2) terms written in pure Korean and Chinese letters, 3) terms from everyday language and technical terms, and 4) the consistency. Six criteria were followed from the aforementioned four perspectives. Finally, various school mathematical terms of South and North Korea were reviewed in the angles of the four perspectives and the six criteria.

The purpose of this study was providing implications in teaching and learning activities to vitalize mathematical communication and to raise positive attitudes about mathematics. We analyzed mathematical communication, disposition and attitudes of the students who had lower mathematical achievement rather than that of Korean language in class using reading materials and strategies. We found that teaching-learning activities using the reading materials and strategies let the low achievers in mathematics communicate more about mathematical notions and problem-solving process actively. The activities triggered interests and attention of mathematics and self-study. In addition, the lessons with reading materials and strategies aroused confidence, will and responsibility to mathematics learning to the students. They made the learners notice mathematics' values and roles and gave the opportunity of reflection about students' learning processes. As a result, the teaching-learning using reading materials and strategies should be developed and accomplished actively in classroom to turn mathematical inclination and attitudes of the students who had had negative inclination and attitudes to mathematics into those of positive and to vitalize mathematical communication to the lower achievers in mathematics.

This paper explores the effects of two different methods of instruction for 106 low-level Korean learners of English at a college in learning request expressions. Both of the methods contained the focus-on-form and function characteristics, while the degree of explicitness for input enhancement was differentiated. Abundant email samples written by English native speakers for the input were provided and email writing practice for the output was proceeded for both groups of the students in the treatment sessions. The numbers of target forms used in pretest and posttest results were compared quantitatively: The tests included email writing and open-ended Discourse Completion Test (DCT). The results indicated that the target pragmatic features were slightly better learned under the condition of relatively high degree of explicit instruction with metapragmatic information, even though the difference was statistically insignificant. In addition, the students' use of request strategies both in email and DCT was affected positively by the treatment with email input and output. That is, the students applied the request strategies they learned through email into their oral production (open-ended DCT) as well as their email writing. Further study on the output effect of target features in advancing pragmatic competence is suggested.

The study focused on exploring the ways that young ESL learners can cultivate media literacy by asking critical questions about the messages embedded in popular American TV cartoons. The participants in the study were five Korean children who came from three different families that had been living in a Midwestern college-town in the U. S. for less than two years. Research methods include analysis of interviews, video-taped sessions and photos of children's drawings. The children were asked about their American cartoon viewing habits as well as critical questions after watching two episodes of their favorite cartoons-Pok$\acute{e}$mon and SpongeBob. The analysis revealed that on one hand popular culture played an important role in helping children to adjust to a new culture and in motivating them to learn English. Further, the children believed that watching American cartoons was helping them improve their English skills. On the other hand, it appeared that they were not accustomed to being asked critical questions and thinking critically while watching American cartoons. Participation in the study increased the children's familiarity with critical questions and critical thinking to varying degrees. Pedagogical implications and suggestions for teachers are discussed.

Environments surrounding production sites have changed greatly in recent years. Accommodating environmental changes calls for the design and development of information systems that center on production lines. There is a need for a training program that teaches learners to understand the particulars of an operation and apply that knowledge to an information system. In this research, we used material requirements planning (MRP) as the subject for which basic skills are to be taught and developed an MRP exercise-based training program. The program is designed for 13 lectures of 90 minutes each, and it consists of MRP exercises, modeling methods to represent them, the use of a programming language for system development, and finally, evaluation of the exercises. Lecture materials are described in 505 lecture slides using Microsoft PowerPoint to allow visualization of topics through graphs and models. The developed training program was then delivered to 86 college students, and its results were measured through quizzes to verify educational effectiveness.

This study examined the texts of the Late Joseon Dynasty's YEONJEONG GASA, whose authors are unknown, to list the contents of education which can be provided by conventional elements. Most existing discussions on expression education have focused on creativity. However, the perspective creativity based on the concepts of modern individualism and difference believes that creation can be done only by special professionals with inborn abilities and is likely to jeopardize the possibility and need of expression education to reduce the scope of expression education. On the other hand, conventionality has been related to "cliche" and "old-fashioned" and considered the counterpoint of creativity with lacking originality and aesthetical or educational valuelessness. Nevertheless, conventionality is valuable as cultural custom in that it is closely related to the contemporary culture, thoughts, and language. Also, it is the power that creates new text and induces sympathy in receivers. The Late Joseon Dynasty's YEONJEONG GASA by unknown authors include typicality of circumstances, schematism of emotion, and formula in conventionality. The positive aspects of conventionality - familiarity and intimacy - are the basis of sympathy and become the power that encourages the public to participate in creation and enjoyment within the frame of creativity. Ultimately, conventionality of YEONJEONG GASA allows learners to experience the pleasure of expression and has an important meaning for expression education as it provides them with the opportunity to perform expressions to extend sympathy.
