To better understand environmental electromagnetic wave exposure during the use of digital textbooks by elementary school students, we measured numeric values of the electromagnetic fields produced by tablet personal computers (TPCs). Specifically, we examined the distribution of the electromagnetic waves for various students' seating positions in an elementary school that uses digital textbooks. Electric and magnetic fields from TPCs were measured using the HI-3603 Visual Display Terminal/ Very Low Frequency (VDT/VLF) radiation measurement system. Electromagnetic field values from TPCs measured at a student's seat and at a teacher's computer were deemed not harmful to health. However, electromagnetic field values varied based on the distance between students, other electronic devices such as a desktop computers, and student posture while using a TPC. Based on these results, it is necessary to guide students to observe proper posture and to arrange seats at an appropriate distance in the classroom. © The Author(s) 2013.

Educational performance based on the learning outcomes of formal schooling in a future knowledge society could be significantly different from that of today. This study investigates the possibilities of developing an educational performance indicator for new-millennium learners (NMLs). The researchers conducted literature reviews, a meeting of experts, pilot studies, and a nationwide survey to define and refine a concept of educational performance required by a knowledge society. The study identified cognitive, affective, and sociocultural domains as core constructs of the indicator. We conducted exploratory and confirmatory factor analysis to validate the indicator. We have identified three domains with four factors in each have to measure the educational performance of NMLs. Information management, knowledge construction, knowledge utilization, and problem-solving abilities are four factors in the cognitive domain. The affective domain consists of self-identity, self-value, selfdirectedness, and self-accountability factors. Finally, the sociocultural domain includes social membership, social receptivity, socialization, and social fulfillment factors.

In the current information society, the need for securing human resources acquired with ICT competency is becoming a very important issue. In USA, England, Japan, India and Israel improving students' ICT competency has become a pedagogical issue. Accordingly, education on ICT competency is changing in many countries emphasizing the basis of computer science. The Korean government revised the ICT curriculum of 2001 focused on the basic concepts and principles of computer science as educational policy in 2005. However, it is still difficult to determine a student's ICT competency level and the outcome of ICT curriculum based on changed direction. Thereupon, this study has developed test tool for measuring the level of Korean elementary school students' ICT competency based on computer science. In this study, 'Content' and 'Information processing' are established as the two axes of the test frame standard through literature research, consideration and discussion. The validity and reliability of questions are verified though the preliminary test and the main test tool has completed through question revisions considering the distribution of answers. About 40,000 students, roughly 1% of the total elementary school students, are selected for the main test. There were several findings made in this study. Korea's elementary school students have a weakness in 'algorithm and modeling'. Information processing stage has been found to vary by grade. A modified 'Angoff method' is used to confirm the spread of the ICT competency levels of the target students. From the results, the cutoff score employed to divide the subjects into three levels, excellent, average and below average, the ratio of excellent levels decreases and the ratio of below average increases in higher grades. To solve these problems, we need to emphasize algorithmic thinking oriented more principal of computer science in ICT curriculum. For more effective ICT elementary education, teaching and learning strategies appropriate for young children to teach computer science should be introduced. © 2010 Elsevier Ltd. All rights reserved.

The purpose of this study is to present innovative approaches for u-Learning environment in public education with Digital Textbook. The Korean Government has been making efforts to introduce the u-Learning environment to maximize the learning effect in public education with Digital Textbook. However, there are only a few studies that analyze the effectiveness of u-Learning environment and Digital Textbook. This paper reviews the current status of u-Learning environment in Korea and analyzes the satisfaction level with Digital Textbooks. The first survey regarding technological factors was collected from 197 students. The results of the survey revealed that the level of satisfaction has declined over a year. The weakness of the study is that the sample frame is insufficient and survey questions did not reflect diverse factors of learning effectiveness. To supplement these shortcomings, 2,226 students were asked about learning performance. The results of the survey showed that the satisfaction with Digital Textbooks is much higher than that of paper textbooks. However, this paper is limited to u-Learning environments in public education. Therefore, research needs to be improved by reflecting both public and private sectors of education in following studies. This paper suggests useful guidelines to educators in improving their u-Learning environment. © 2012 KSII.

In this paper, a support plan for marriage immigrants with low level of education to acquire a degree through E-learning was studied. Currently, the number of Korean men marrying foreign women is rapidly increasing due to the increase in the imbalance of gender ratios caused by preference for boys and shunning of rural areas by Korean women. As a result, there is a large influx of immigrants from neighboring countries. However, the marriage immigrants are experiencing significant difficulties in adjusting to the Korean societies due to the language barrier and low income. To alleviate this problem, the Korean government is performing various social adaptation programs such as Korean language education and vocational education. Most marriage immigrants, however, are not properly educated as they are burdened by their household duties or work. In this study, a plan for supporting marriage immigrants to acquire a degree through Korean language and vocational educations through the internet was researched. To achieve this goal, a survey of intentions of the marriage immigrants to acquire an academic degree was performed. As a result, marriage immigrants who want a degree through E-learning have a strong intention of continuing their education, have an experience of internet lectures, are living mostly in Seoul, Daegu, Gwangju, Daejeon, Choongnam, Jeonbuk, and Jeju, and are mostly from Vietnam, Cambodia, and Uzbekistan. Also, those who do not have an occupation and are young, especially those in their 20s, were found to have a strong intention of learning. These characteristics were considered in this study to propose methods to acquire a degree through internet lectures alone, to develop E-learning contents combining language of marriage immigrants with high demand for education, to establish a class for marriage immigrants in air and correspondence high schools located in areas with significant population of marriage immigrants with high demand for education, and to devise a plan for combining vocational education and degree acquisition by recognizing vocation educations provided at various institutions as credits at Lifelong Education Account System and air and correspondence high schools. Above measures are expected to support the marriage immigrants with low level of education to settle as equal members of the society instead of deteriorating into an underprivileged class by providing them with an opportunity to receive education.
