The purpose of this study is to analyze the content features of educational technology curricula for primary education developed by national governments. A qualitative cross-case document analysis of the national educational technology curriculum of Norway, Flanders and England was conducted. The analysis focuses on the underlying visions, specific aims and instruction related aspects that are integrated in the national educational technology curricula of the three cases under investigation. The results indicate that specific aims mainly focus on the critical use of educational technology; safe and responsible use of educational technology; information retrieval, processing and production; communication by use of educational technology; and use of educational technology for subject learning. It is possible that a discrepancy exists between the concepts of digital literacy and the specific aims that are addressed in educational technology curricula. Moreover, the rationales that underlie educational technology curricula represent a catalytic and social point of view rather than an economic one. The implications of our findings for curriculum developers and researchers are discussed. 相似文献

A review of studies published between 1980 and 2005 shows a significant positive effect of specialized training on the competency of caregivers in childcare (d = 0.45, S.E. = 0.10). Experimental results from the meta-analysis were significantly smaller for settings with no fixed curriculum content, delivery of the training at multiple sites and large-scale programs. Results were also smaller when tests were used that did not align closely with the content of the training. Furthermore, experimental results were smaller for the skills domain, compared to the knowledge and attitude domain. A subset of experiments with both caregiver and child data also showed a positive effect, supporting the causal link between caregiver training, caregiver competencies and child behavior in childcare, although this effect was not significant due to the small number of studies (d = 0.55, S.E. = 0.30). Based on these findings, we advocate the inclusion of instruction related to teacher–child interaction in the curriculum of vocational training for caregivers. 相似文献

The outcomes of an international collaborative project are presented, involving experienced teacher educators and researchers from eight different countries, who engaged in a series of structured discussions on the professional development of teacher educators. We start with an overview of the needs in practice and policy, as well as the research interests, making structured opportunities for teacher educator development necessary. As a first outcome, we present a model to conceptualise teacher educator development, grounded in a study of the international literature and the systematic critical discussion of its findings by the participants in the project. The model facilitates international (research) collaboration, mapping and guiding initiatives in policy and practice by providing both an overview of the complexities of teacher educator development and a language to discuss them. The second –structural- outcome is the establishment of InFo-TED – the International Forum for Teacher Educator Development. 相似文献

A content analysis of the textbooks used in the Dutch early childhood teacher education shows clear inconsistencies with the intended curriculum. Neither the content standards found in the professional profile for teachers nor the content standards from the educational profile of their training courses are adequately covered in the books. Whilst they pay considerable attention to the teacher's educational duties, other tasks outside the primary work process are either dealt with in much less detail or ignored altogether, including the need for strategic planning, for reflection and evaluation, for the development of educational policy, and for co-operation and liaison with colleagues from other disciplines. 相似文献

IntroductionLeukolysis-related pseudohyperkalemia due to preanalytical procedures may lead to erroneous (or absence of) treatment based on an invalid lab test result. We aimed to obtain a leukocyte threshold above which leukolysis-related pseudohyperkalemia becomes clinical relevant. Secondly, temporal dynamics of treatment-induced leukocyte decrease were studied to allow tailored implementation of laboratory information system (LIS) decision rules based on the leukocyte threshold to avoid leukolysis-related pseudohyperkalemia.Materials and methodsPotassium results of AU5811 routine chemistry (Beckman Coulter, Brea, California, USA) and iStat point of care (POC) (Abbott Diagnostics, Chicago, Illinois, USA) analysers were compared, the latter method being insensitive to leukolysis caused by pre-analytical procedures. Potassium results were combined with leukocyte counts obtained using a Cell-Dyn Sapphire haematology analyser (Abbott Diagnostics, Santa Clara, California, USA), resulting in 132 unique data triplets. Regression analysis was performed to establish a leukocyte threshold. The Reference Change Value (√2 x Z x √(CVa2 + CVi2)) was used to calculate maximum allowable difference between routine analyser and POC potassium results (deltamax + 0.58 mmol/L). Temporal analysis on the treatment-induced leukocyte decrease was performed by plotting leukocyte counts in time for all patients above the threshold leukocyte count (N = 41).ResultsEstablished leukocyte threshold was 63 x109/L. Temporal analysis showed leukocyte counts below the threshold within 8 days of treatment for all patients.ConclusionsBased on performed analyses we were able to implement LIS decision rules to reduce pseudohyperkalemia due to preanalytical procedures. This implementation can contribute to a reduction in erroneous (or absence of) treatments in the clinic. 相似文献

An e-TextBook can serve as an interactive learning environment (ILE), facilitating more effective teaching and learning processes. In this paper, we propose the novel concept of an EPUB 3-based Hybrid e-TextBook, which allows for interaction between the digital and the physical world. In that regard, we first investigated the gap between the expectations of teachers with respect to e-TextBook functionalities, on the one hand, and the ILE functionalities offered by e-TextBooks, on the other hand. Next, together with teachers, we co-designed and developed prototype EPUB 3-based Hybrid e-TextBooks that make it possible to connect their learning content to smart devices in classrooms, leveraging both digital publishing and Semantic Web tools. Based on experimentation with our prototype Hybrid e-TextBooks, we can argue that a semantically enriched EPUB 3-based Hybrid e-TextBook is able to act as a comprehensive ILE, providing the tools needed by teachers in smart classrooms. Furthermore, expert observations and Smiley o’meter results demonstrate an effective impact on student cognition and motivation. 相似文献
