Can EFL Speakers Communicate in English-mediated Classes?: A Case of a Liberal Arts Class for Engineering Students in Korea

The purpose of this paper is twofold: (1) to explore what factors prevent English as a foreign language (EFL) students from participating in English-medium instruction classes; and (2) to examine how dialogic teaching techniques enhance students’ participation in classroom interaction. Utilizing the notions of “communicative competence” and “truncated repertoire,” we first investigated the barriers to communication in classrooms. We next examined how EFL speakers are able to communicate in English-medium instruction (EMI) classes. The findings suggest that when the instruction was designed to reduce cultural barriers and to facilitate authentic discussion, EFL students were able to participate in classroom interaction, and they perceived discussion as a way to learn an unfamiliar subject taught in English.     

Low-cost,disposable microfluidics device for blood plasma extraction using continuously alternating paramagnetic and diamagnetic capture modes

Blood plasma contains biomarkers and substances that indicate the physiological state of an organism, and it can be used to diagnose various diseases or body condition. To improve the accuracy of diagnostic test, it is required to obtain the high purity of blood plasma. This paper presents a low-cost, disposable microfluidics device for blood plasma extraction using magnetophoretic behaviors of blood cells. This device uses alternating magnetophoretic capture modes to trap and separate paramagnetic and diamagnetic cells away from blood plasma. The device system is composed of two parts, a disposable microfluidics chip and a non-disposable (reusable) magnetic field source. Such modularized device helps the structure of the disposable part dramatically simplified, which is beneficial for low-cost mass production. A series of numerical simulation and parametric study have been performed to describe the mechanism of blood cell separation in the microchannel, and the results are discussed. Furthermore, experimental feasibility test has been carried out in order to demonstrate the blood plasma extraction process of the proposed device. In this experiment, pure blood plasma has been successfully extracted with yield of 21.933% from 75 μl 1:10 dilution of deoxygenated blood.     

开放大学面临的挑战：来自韩国的案例

韩国国立开放大学有过成功的历史，但目前它正处在困境之中。本文通过数据分析，描述了开放大学所存在的主要困难：①报名人数和在学学生的人数急剧减少；②学生注册率呈连续下降趋势；③学生出现女性化和大龄化的趋势；④学生数量少于招生指标的院系数目增多，不同院系学生数量之间的差距增大。根据韩国开放大学的经验，作者提出以下建议：把学生数维持在一个合理的范围内；开放大学要尽力提高教育质量。     

Examining the development of action learning practice in South Korea

This year marks the 25th anniversary since action learning (AL) was first introduced in 1993 in South Korea. Although AL has greatly contributed to meeting organizational needs so that it would result in its strong presence as an organizational learning tool, there is no single review study on the development of AL practice in Korea. The purpose of this study, therefore, was to examine the development of AL practice in Korea to understand its current state and envision the future. To that end, two research questions guided our inquiry: What are the distinctive features of the development of AL practice in Korea? What is unique about the development of AL practice in Korea? To answer the two research questions, we conducted semi-structured interviews with 13 AL practitioners who have experienced AL practice for many years, analyzed 13 annual AL conference proceedings published since 2005, and reviewed Korean publications on AL published since 2000. Based on the triangulated data analysis, we discuss the uniqueness of the development of AL practice in Korea and implications for research and practice.     

Reading Achievement in the Middle School Years: A Study Investigating Growth Patterns by High Incidence Disability

Numerous research studies (e.g., Anderson, Kutash, &; Duchnowski, 2001; Lane, Carter, Pierson, &; Glaeser, 2006 Lane, K. L., Carter, E. W., Pierson, M. R., &; Glaeser, B. C. (2006).

Growth in reading achievement of students with disabilities, age 7 to 17. Exceptional Children, 78, 89–106.[Web of Science ®] , [Google Scholar]) have shown that students with disabilities generally exhibit lower reading scores than their peers without disabilities. However, questions remain about the possibility of longitudinal differences among high-incidence disability classifications (e.g., speech/language impairments, SLI; emotional disturbances, ED; learning disabilities, LD; and attention deficit disorders, ADD). This study investigated growth patterns in reading achievement among middle school students from 5th to 8th grade with different high incidence disability classifications on one state's high-stakes assessment. After a repeated measures analysis of variance and post hoc testing, results reveal that students identified as LD and SLI evidenced more growth in reading than those classified as either ADD or ED. In light of the No Child Left Behind Act of 2001 legislation, findings about the various growth patterns are discussed with respect to policy, measurement, and practical implications.
