The goal of this study is to explore the possibility of applying the podcasting in Korean education for foreign students. To achieve this goal, concepts and applicability of the podcasting is discussed. Previous studies on foreign language education are reviewed and the cases on Korean language education based on technology using mobile phones are investigated. Some of the outstanding merits of the podcasting are found to be its accessibility, mobility and variability along with its room for control by the learners. It also enables the learners to be motivated and to enhance their learning ability. In addition, the podcasting with the content-based instruction is applied for the foreign students majoring in business and its results and implications are discussed. Based on the above results of this study, more active discussions are expected on such issues as educational designs through the podcasting, related variables and the performance evaluation.

This paper presents a novel approach in the design of a CAM for an asynchronous cache. The architecture of cache mainly consists of four units: control logics, content addressable memory, completion signal logic units and instruction memory. The pseudo-DCVSL is useful to make a completion signal which is a reference for handshake control. The proposed CAM is a very simple extension of the basic circuitry that makes a completion signal based on DI model. The cache has 2.75KB CAM for 8KB instruction memory. We designed and simulated the proposed asynchronous cache including CAM. The results show that the cache hit ratio is up to 95% based on pseudo-LRU replacement policy.

The purpose of the study was to determine the effect of a practical problem-based instruction(PPBHEI) perceived by female and male high school students. One Group post-test only design was used in this quasiexperimental study. The experimental group of the study was 101(67 male and 34 female) second grade students of a high school in Kyung Kee Area. The Practical Problem-Based Home Economics Instruction had been conducted to the group during the 14th weeks of 1997 spring semester. Post-test including the two parts was conducted at the end of the semester. The instrument of the study was developed and used, based on the previous literature after testing validity and reliability by the researcher. The questionnaire was composed of open-ended question. The data of this study were analyzed by content analysis. The results were as follows: 1)both female and male respondents indicated PPBHEI helped to improve their friendships(93.1%), expression skills(69.3%), their thinking ability(82.1%), and problem soiving skills(76.2%); 2)both female and male respondents indicated that problems of PPBHEI were that a few students didn't like joining the class and classroom space was too small; and 3)half of students(52.3%) perceived the Practical Problem-Based Home Economics Instruction related to student achievement.

This study was conducted as a part of the project to evaluate the quality of mathematics instruction in the national curriculum system. The purpose of this study is to measure the consistency between teaching goals of mathematics curriculum, contents presentation of textbooks, and testing including adequacy of each element in mathematics instruction for 8th grade. To do this, we used MIQP (instructional quality profile for Mathematics) developed basing on the instructional quality profile (IQP) in the previous research of the project. First, the quality of textbooks' content presentation for 8th grade was found that the desirable levels in number and operation area and geometric area was relatively less compared to other areas, but it was generally good. Second, it was found that the quality of mathematics testing for 8th grade was good in terms of consistency with the curriculum's teaching goals, consistency with the content presentation of textbooks, and adequacy of testing. However, regional differences in the quality of testing showed that there were some deficiencies in regions outside the metropolitan.

Purpose: The purpose of this study was to identify and assess from nursing students and nurses in the clinical field what constitute good instruction, through the review of nursing students' opinions and clinical field demands. Methods: The study design was used Creswell's exploratory sequential design by collecting and analyzing qualitative data obtained from interviews and then analysis of quantitative data. The participations were 79 seniors in nursing schools and 85 nurses with less than three years of clinical experience. The data were collected through individual interviews and analyzed based on Elo and Kyngas's content analysis method. The quantitative data were collected using the questionnaire developed based on qualitative results and analyzed by SPSS 23.0 program and Importance Performance Analysis (IPA). Results: The results showed that IPA extracted seven items with high importance but low satisfaction: "nursing fads and trends," "teacher-learner communication and reflection," "materials used in clinical settings such as monitoring results and test results," "special presentations by experienced practitioners," "instruction assures learners' comprehension," "accurate and detailed evaluation standards" and "feedback on homework and exam." Conclusion: The factors comprising good instruction were verified, and the necessity for additional efforts to improve high importance and low performance factors was noted. Therefore, this study can serve as a guide for nursing education facilities and educators in developing of a thorough education system with excellent instruction designed to achieve an ideal nursing education.

The purpose of this study was to explore the possibility of mathematical instruction through performance task activities based on the The Backward Design, which was suggested at first by Wiggins & McTighe in 1998. The Design deals with a performance assessment task involving the whole objective and its entire content of a lesson. Based on the Backward Design, this study established the mathematical instructional materials, which deal with the concept of 'the sector' taught in middle school, with one large performance task including three small tasks. It is important that in the lesson students be guided to achieve the several learning goals by themselves through reasoning activities. For this purpose, a formal interview was carried out by the subject of three middle school mathematics teachers. As a result, in order to implement the instruction utilizing the performance tasks more efficiently in future, it is required that a large performance task should be selected or developed including the content or problem contexts to be relevant with the real-life challenging situations. In addition, to make students enhance reasoning skills, it is strongly requested that the tasks including the utilization of supplementary materials such as technological devices or manipulatives be dealt with in a lesson.

The purpose of this study is to help the students in middle school improve their English listening comprehension by presenting effective teaching and learning techniques using animation. A good animation provides a self-contained world with language expressed in a virtual context. A few animation such as "Mulan", "The Emperor's New Clothes", and "Gulliver's Travel" are presented. The materials are primarily for English listening comprehension, enhance awareness of American culture and life-styles, and to encourage students' active role in learning English. It is suggested that their use with content-based instruction, where animation provides relevant schema background, makes language relevant and comprehensible. Practical aspects of classroom instruction are discussed, focusing on the adaption of pre-viewing, while-viewing, and post-viewing activities to the selected animation. It is concluded that careful animation selection, purposeful lesson planning, and the integration of pre-viewing, while-viewing, and post-viewing activities into the content-based lesson encourage natural language skills, especially the listening comprehension and students' interest in English.

During the last three decades, earth science has been re-conceptualized as an interdisciplinary discipline entitled Earth System Science (ESS), which is based on knowledge of the physical earth system and human impact on the earth. While there is increasing effort to teach earth as a system in K-12 education, teachers' preparedness of to teach earth system is still in its infancy. This article focuses on reviewing the literature of teachers' knowledge of earth systems and of how teachers' knowledge of subject matter affects their teaching practice and pedagogical content knowledge (PCK). First, the study investigated a literature of PCK in general as well as in science teaching. Then this study duscuss what teachers' subject matter knowledge (SMK) is and what it means to be in teaching earth system science. Third, a literature of teachers' knowledge of earth system was reviewed. Finally, a number of suggestions and implications are made as to what teacher education program should do to better prepare future teachers to teach earth systems.
