  • Adaptive learning in e-learning has garnered researchers' interest. In it, learning resources could be recommended automatically to achieve a personalized learning experience. There are various ways to realize it. One of the realistic ways is adaptive learning path recommendation, in which learning resources are provided according to learners' requirements. This paper summarizes existing works and proposes an innovative approach. Firstly, a learner-centred concept map is created using graph theory based on the features of the learners and concepts. Then, the approach generates a linear concept sequence from the concept map using the proposed traversal algorithm. Finally, Learning Objects (LOs), which are the smallest concrete units that make up a learning path, are organized based on the concept sequences. In order to realize this step, we model it as a multi-objective combinatorial optimization problem, and an improved immune algorithm (IIA) is proposed to solve it. In the experimental stage, a series of simulated experiments are conducted on nine datasets with different levels of complexity. The results show that the proposed algorithm increases the computational efficiency and effectiveness. Moreover, an empirical study is carried out to validate the proposed approach from a pedagogical view. Compared with a self-selection based approach and the other evolutionary algorithm based approaches, the proposed approach produces better outcomes in terms of learners' homework, final exam grades and satisfaction.

  • Developing countries, including Africa, are experiencing very little human resources development due to the deprivation of equal educational opportunities, poor educational conditions, and the gap in information technology with developed countries. Developing countries that do not have excellent human resources are lagging behind in globalization competition with developed countries, and the problem of 'human resource development' in developing countries can not be avoided. In developing countries, education budgets are too low to meet education needs and compulsory education, and therefore they are not adequately responding to the increasing demand for education. The lack of education budget is due to the lack of education infrastructure. In this study, the NAS based server is configured to configure functions such as educational content and learning management, and the client area is presented with solutions for various media such as tablet, PC, and beam projector. And to support optimized e-learning services in developing countries by constructing a SCORM-based platform.

  • Background: YouTube has become a popular source of healthcare information in orthopedic surgery. Although quality-based studies of YouTube content have been performed for information concerning many orthopedic pathologies, the quality and accuracy of information on the rotator cuff have yet to be evaluated. The purpose of the current study was to evaluate the reliability and educational content of YouTube videos concerning the rotator cuff. Methods: YouTube was queried for the term "rotator cuff." The first 50 videos from this search were evaluated. Video reliability was assessed using the Journal of the American Medical Association (JAMA) benchmark criteria (range, 0-5). Educational content was assessed using the global quality score (GQS; range, 0-4) and the rotator cuff-specific score (RCSS; range, 0-22). Results: The mean number of views was 317,500.7±538,585.3. The mean JAMA, GQS, and RCSS scores were 2.7±2.0, 3.7±1.0, and 5.6±3.6, respectively. Non-surgical intervention content was independently associated with a lower GQS (β=-2.19, p=0.019). Disease-specific video content (β=4.01, p=0.045) was the only independent predictor of RCSS. Conclusions: The overall quality and educational content of YouTube videos concerned with the rotator cuff were low. Physicians should caution patients in using such videos as resources for decision-making and should counsel them appropriately.

  • A school library is an institution that supports the school's educational objectives through various educational activities based on information resources, and teachers' perception is essential to connect resources and users. However, most studies have been conducted based on the self-perception of teacher librarians. This study aims to understand the effect of teachers' experience of library programs and cooperative classes with the school library on their perception of the school library roles and librarian teachers' professionalism. A questionnaire survey was conducted on 78 teachers at eight national and public high schools in Seoul and Gyeonggi Province, and the results were statistically analyzed using factor analysis and regression. As a result, it was found that the teachers' experiences affect their perception of the school library's roles, especially informational, educational, and cultural roles. Also, the teachers' experiences affect their perception of librarian teachers' educational support and library expertise. Based on the results, considerations in school library programs and cooperative classes were suggested to improve teachers' perception of the school library roles and librarian teachers' professionalism.

  • As the teaching environment of schools has significantly shifted toward using various types of educational contents, the need for the use of educational contents as class resources has increased. Having an archive is an effective way of organizing information that can provide various educational contents. The National Archives (TNA) of the UK has been actively producing and providing educational contents for teachers and students for a long time. The purpose of this study is to analyze in depth the detailed examples and structure of the contents, the process of producing educational contents, and the methods of providing various contents of the TNA, which systematically provides diverse educational contents. It intended to help archivists discover the educational values of archives in providing users with various types of educational contents. Then, the study compared the analysis results with the National Archives of Korea and suggested for its improvement, as well as that of other archives in the country.

  • This study attempts to review the present situations of rural schools in South Korea, to analyze problems regarding the educational environments for their students, and to present direction for improving toward better educational environments. All the data and information are based on using avaiable documents and personal macro observation and insights. The sharp decrease of rural population for recent decades has made lots of public schools unexceptionall much smaller by school number and students' number. Nearly five thousands of rural small schools have already been abolished and the rest are also endangered to be dosed. In order to tackIe such problem, the Government has been trying to provide rural students with better educational environment, but failed to attract them to stay in rural schools. Most of rural school students have poorer family environment, underprivilged school learning environment, and less civilized community environment. Those normal parents living in rural areas are likely to send their kids to urban schools for prior opportunities to enter better quality of higher level of schools and then the remained attending rural schools are those who live with grand parents or whose parents are very disadvantaged. The rural school teachers are teaching much less number of students compared to urban teachers, but their students are less achieved learners. Notwithstanding their abudant natural community learning environments, the rural school students are less making use of those resources and less benefited from more civilized life due to their underdeveloped community conditions. In order to improve such educational environments, incentives for young couples to safely reside in rural communities, incentives for better qualified teachers to preferably work for rural schools, better learning facilities for rural school students and for better vocational experiences, lifelong learning opportunities for all community people, and increased public support to rural development for rural people not to worry about their rural lives, need to be guarantyed.

  • This thesis examined and analyzed the occupational status of the promising occupations in the environmental industry. A study on the status of the occupations in the environmental industry is very necessary for planning policies and improving occupations in the environmental industry. Studies and discussions regarding the status of the occupations in the environmental industry, however, were extremely insufficient. A survey of the employees in the environmental industry was conducted in order to certainly comprehend the status of the occupations, educational and training programs, and occupational changes and to utilize the result of the survey as foundational data necessary for occupational studies in the environmental industry. The subject of the survey was limited to the employees who had work for one or more years in twenty promising occupations in the environmental industry. The content of the survey was occupational performance competencies, occupational careers, the degree of occupational satisfaction, vocational education and training, working conditions, occupational changes, and the security of the human resources. Dissimilarities as well as similarities among twenty promising occupations were discovered according to the analysis result of the occupations in the environmental industry. A major discovery was that there are lots of difficulties in securing environment-related human resources. Primary reasons for the difficulties were inconsistent working conditions and the shortage of the qualified human resources. To solve the difficulties in securing the human resources, the curriculum of the educational and the training institutes should be innovated and the human resources from the institutes could be applied to the workplace directly after the graduation.

  • Prisons are mostly filled with social deviants and like other correctional institutions, deserve organized information (provision) centers such as library. A study on library resource needs and accessibility by prison inmates was conducted at Kuje prison, Abuja and Kaduna prison, Kaduna, Nigeria, both of which have functional libraries. A sample of 898 inmates was randomly selected from all the convicted inmates in the two prisons. A total of 106 inmates were selected from Kuje prison and 792 from Kaduna prison. A well-structured questionnaire was used to collect data from the inmates. All the 898 inmates responded. A total of 786 (87.9%) males and 112 (12.4%) females were involved in the study. With regards to the educational level attained by the inmates, 347 (38.6%) had Junior Secondary School Certificate while 323 (30.0%) had Senior School Certificate both accounting for 74.6% of the sampled population. In areas of information needs, 94.5%, 96.1%, 98.7%, 99.4%, 100%, and 100% of the respondents indicated that information on current affairs, survival and coping, educational support, legal aid, skill acquisition, and health, respectively were highly needed by the inmates. Out of the 12 information resources listed, only newspaper, novel, handbook and manual, and bulletin were readily accessible with percentage accessibility of 60.7, 7.8, 6.8, and 1.9, respectively. One major reason adduced by the respondents for limited access to information resources was the very strict rules and regulations in the prison. Providing more library resources and granting the inmates more access to the library would assist in character reformation and rehabilitation of the inmates.

  • In this research, the change of Korean middle-school science education environments is investigated through analyzing eighth graders' survey data collected over the past 20 years of TIMSS. We extracted educational context variables that provide meaningful information on changes of Korean science education, and have been surveyed more than 3 study cycles up to TIMSS 2015. The selected educational context variables include school resources and school climate from the school principal's questionnaires, and teacher characteristics and instructional activities from the teacher's questionnaires. For each context variable, we analyzed its trend over TIMSS cycles, and discussed its implications in light of Korean educational policy and curriculum changes. Based on the results, we recommended several ways that help to improve science teaching and learning in light of lab assistants, computer availability, teacher learning community, and middle school Earth science curriculum.

  • In the age of knowledge and information when every aspect of economy, education and culture in society is changing rapidly, the teacher is not just a provider of knowledge in classroom. Ultra-modern educational tools and materials have come into being with the latest developments in science and technology and we see classroom teaching in general tending towards more 'open' classroom and study. What the students need most for the coming century is the cultivation of higher faculties such as creative thinking, the power to solve problems, and the spirit of inquiry. The present-day teacher is required to make use of various teaching medial in order to provide the students with better educational environment for developing these faculties, not the teaching method of the past with the teacher at the center. One way to enhance classroom environment is in reintroducing the modernized teacher's desk to the center of teaching apparatus. This paper is about the better way of designing the teacher's multimedia desk equipped with a PC that will make it possible for the teacher to utilize the internet-based educational resources.
