Optical excitation and external photoluminescence quantum efficiency of Eu3+ in GaN

We investigate photoluminescence of Eu-related emission in a GaN host consisting of thin layers grown by organometallic vapor-phase epitaxy. By comparing it with a reference sample of Eu-doped Y2O3, we find that the fraction of Eu3+ ions that can emit light upon optical excitation is of the order of 1%. We also measure the quantum yield of the Eu-related photoluminescence and find this to reach (similar to 10%) and (similar to 3%) under continuous wave and pulsed excitation, respectively.Stichting voor de Technologische Wetenschappen (STW); Japan Society for the Promotion of Science [19GS1209, 24226009]; Ministry of Education, Culture, Sports, Science and Technology of Japaninfo:eu-repo/semantics/publishedVersio

ASSISTIVE TECHNOLOGY FOR EDUCATING PERSONS WITH INTELLECTUAL DISABILITY

Technology has changed and continues to change the way people manage things in their lives and it is analogous in the life of Persons with Disabilities (PwDs) through integration of technology in education. Meaningful inclusive education can be made possible with the help of Assistive Technology (AT) since it helps in identifying and overcoming all barriers for effective, continuous and quality participation of all PwDs including those with intellectual disabilities in education. This article attempts to put forward few measures that provide effective education to Persons with Intellectual Disability through the support of assistive technology specifically designed by understanding their educational needs in order to maximize their academic success. Assistive technology pertinent to various domains of education and developmental areas with appropriate examples and case study is also being illustrated. Barriers to access assistive technology and recommendations to remediate it are also discussed in comprehensive manner.  Article visualizations

Возможности развития информационных технологий в учебных заведениях среднего общего и специального образования в рамках интеграции в единое информационно-образовательное пространство

Directions of developing of information technologies in education must provide the developing of network technologies and communications, which permit to develop a technology of a distance and unbroken (continuous) educatio

Attitudes toward continuous learning and new communication technologies

In this study, based on a representative sample of 1000 respondents, we analyzed the attitude of active population in the Republic of Macedonia toward continuous learning and new communication technologies. Starting from the definition that learning is a process of creation of a relatively permanent change in attitude towards the future, for the promotion of the way of thinking and as a special importance, the attitude of the active population toward continuous learning occurs. A positive attitude toward learning is the basic premise for the introduction of lifelong learning in entrepreneurship development. Attitude toward new communication technologies is also important as for the continuous learning as well for start up, sustainability and gaining a competitive advantage in the entrepreneurial businesses. First, we analyzed the correlation between the preferences of autonomous work, technology and continuous learning, then, the differences derived from age, ethnicity, education, and socioeconomic status. The results show that there is a correlation between the preferences of autonomous work, new technology and continuous learning. The results allow creation of specific approach to formal and informal education for improving of the entrepreneurial mindset

THE ROLE OF BLOCKCHAIN TECHNOLOGY IN FACING REVOLUTION EDUCATION 4.0

Although several concepts for implementing education exaggerated using blockchain technology, t agreements which are allocated ledgers carefully and thoroughly. Blockchain technology, unlike databases that are processed by certain forces that provide policies in correctness of data through real-time implementation, Blockchain is a digital data storage system containing records that are connected via cryptography. Blockchain technology has now been used by various sectors, one of which is for transactions in cryptocurrencies such as Bitcoin. The benefit of the blockchain technology approach in education is that people who do not have knowledge of blockchain technology can benefit from blockchain technology, because a lot of the data generated by this sector is continuous from education to Bachelor. Blockchain, can be used as, "a machine to create high-level security and reliable security", the high level of security and efficiency of blockchain as a storage place for financial transactions and data has opened up opportunities for innovation in education as a storage for educators and students' data

Bellcurve: Built Environment Lifelong Learning Challenging University Responses to Vocational Education: Lifelong University for the Built Environment

BELLCURVE (Built Environment Lifelong Learning Challenging University Responses to Vocational Education) is a European Commission funded research project conducted at the School of the Built Environment, University of Salford, UK, in collaboration with Department of Construction Economics and Property Management, Vilnius Gediminas Technical University, Lithuania and Department of Building Production, Tallinn University of Technology, Estonia. This project addressed issues associated with the mismatch between graduate skills and labour market requirements as this mismatch has been identified as one of the main factors behind graduate unemployment and employer dissatisfaction, particularly in the Built Environment (BE) sector. BELLCURVE considered ‘student engagement’ as a continuous through-life process rather than a temporary traditional engagement limited by the course duration. This through-life studentship defines the essence of the new innovative “Lifelong University” concept, whereby providing an opportunity for learners to acquire and develop skills and knowledge enabling responds to changing construction labour market needs on a continuous basis. This requires a reform in governance systems to respond labour market needs effectively while promoting the lifelong learning agenda

[8]) and its interrelation with the notion “steepness” of locally Lipschitz functions are discussed. A deformation lemma and a mountain pass theorem for usco mappings are proved. The relation between these results and the respective ones for lower semicontinuous functions (cf. [7]) is considered

CONSULTING AS A PEDAGOGICAL GUIDANCE TECHNOLOGY IN THE CONTINUOUS EDUCATION OF A PEDAGOGUE

The present day tendency of rapid constant changes of the informational and technological space surrounding a pedagogue, suggests the necessity of continuous education. The necessity of constant renovation of knowledge leads a pedagogue to obtain new competences, to the emergence of new educational practices. As a result of high competition in all spheres of society the client-orientated course of modern system of professional education makes a pedagogue search for new forms of getting competences, which are not set in the frames of certain disciplines and thus provide the continuity of educational processes. Here we suggest consulting, having been worked out as a pedagogical technology that guaranties the achievement of the set goals, reproduction and replication. The purpose of our research is to substantiate the expediency of using the pedagogical technology of consulting to support the process of continuous professional training of a teacher directly at the workplace. The article deals with the theoretical stage results of our research in working out a consulting model as a pedagogical technology of continuous pedagogue’s educational guidance as well as the analysis of pedagogue-participants’ opinions concerning the pilot approbation of this model

Problems Faced by Secondary Technology Education Novice and Veteran Teachers

The purpose of this study was to examine the challenges faced by secondary technology education (TE) teachers in Illinois. Specifically, the study sought to identify and categorize a list of challenges encountered during their first years in the TE profession as well as challenges that veteran TE teachers are facing in their current teaching assignment. Seventy-three TE teachers completed an online questionnaire. Twenty-six challenges were identified and of the top five challenges, only three, equipment, funding, and understanding what TE is were identified as a continuous challenge at each career stage. Knowing the challenges identified by TE teachers at different career stages can assist school administration and TE professionals in providing specific support to address these problematic areas in efforts to improve retention rates among TE teachers
