This paper reports research into the student experience of learning through discussions in a blended environment. Third year engineering students studying e‐commerce engaged in both face‐to‐face discussions and online asynchronous discussions as key aspects of their learning experience. Adopting a quantitative methodology, questionnaires were completed by students at the end of their learning experience. The results suggest qualitatively different experiences of learning through discussions. The results show that students who have a deep understanding of how the discussions are related to their learning outcomes tend to approach the discussions in more meaningful ways. In the face‐to‐face context, their approach emphasizes learning through the experience of others and, in the online environment, their approach emphasizes reflecting on the problems discussed from a variety of perspectives. Formation par discussions dans des environnements intégrés. Une étude a été menée sur les expériences d’étudiants avec la formation par discussions dans un environnement intégré. Des étudiants d’ingénierie de troisième année ont engagé des discussions personnelles et des discussions en ligne différés lors de leurs études de commerce en ligne représentant les aspects clés pour leur expérience de formation. En adoptant une méthode quantitative, des questionnaires ont été remplis par des étudiants à la fin de leur expérience de formation. Les résultats suggèrent des expériences de formation qualitativement différentes par discussions. Les résultats montrent que les étudiants qui ont une grande connaissance sur le fait que les discussions influent sur leur issue de formation, tendent à aborder les discussions de manière plus significative. Dans un contexte personnel, cette évaluation met l’accent sur la formation par l’expérience d’autres, et dans l’environnement en ligne, elle met l’accent sur la réflexion des problèmes discutés avec une variété de perspectives. Lernen durch Diskussionen in integrierten Lernumfeldern. Diese Studie berichtet über die Erfahrungen von Studenten beim Lernen durch Diskussionen innerhalb eines integrierten Lernumfelds. Studenten des Ingenieurwesens im dritten Studienjahr befassten sich während ihres e‐Commerce Studiums sowohl mit persönlichen Diskussionen als auch mit zeitlich versetzt geführten Online‐Diskussionen, die Schlüsselaspekte für ihre Lernerfahrungen darstellten. Mit einer quantitativen Methode wurden am Ende der Lernerfahrung durch die Studenten Fragebögen ausgefüllt. Die Ergebnisse zeigen qualitativ unterschiedliche Lernerfahrungen durch Diskussionen auf. Sie belegen, dass Studenten, die gute Kenntnisse darüber haben, wie Diskussionen ihren Lernerfolg beeinflussen, bedeutend mehr dazu tendieren, an Diskussionen teilzunehmen. Dieser Ansatz beweist, dass in persönlichen Diskussionen der Lernerfolg durch die Erfahrung anderer erreicht wird, wohingegen bei einer Problemdiskussion innerhalb eines Online‐Umfelds der Schwerpunkt auf die Vielfältigkeit der Betrachtungsweisen aus verschiedenen Blickwinkeln gelegt wird. Dieser Ansatz hebt im persönlichen Kontext das Lernen durch die Erfahrung anderer und in der Online‐Umgebung die Betrachtung über die aus vielen Blickwinkeln diskutierten Probleme hervor. 相似文献

This article describes a collaborative action research process in pre-school and primary education in Spain during a four-year period (2006–2010). The aim was the need to promote a level of reflection among the participants as to their teaching practice. The methodology used was a technologically mediated action research process. The results are analysed based on the constructed meanings in the area of practice, innovation strategies used and the degree of collaboration reached in the research. Finally, conclusions are made regarding the essential need to prioritize the research and professional development of teachers in the innovative use of technology. It proved necessary to promote collaboration in action research in order to rethink and negotiate the use of technology in a social learning environment. 相似文献

This paper aims to analyze the companies’ view about the financial valuation of intangibles relevance and its influence on corporate performance. Based on the theory of resources, the role of intangibles in business competitiveness is justified. The traditional factors of production have become secondary, while the success is primarily based on the development and utilization of intangible resources. One of the main problems in managing the intangibles appears to be that, there is a general lack of information about them. Therefore, financial valuation of intangibles will result in significant benefits to the organization that will help determine business strategy, process design as well providing competitive advantage. It follows the hypothesis of this work, the greater known about their intangibles and the greater sensitivity to the financial valuation of them, the better performance. To achieve this objective, a field study is done, doing telephone calls to Basque Country companies’ financial managers. 相似文献

Previous research has extensively evaluated the impact of delay on the value of positive reinforcers, but the study of its impact on the value of aversive consequences is scarce. The present study employed a modification of Evenden and Ryan’s procedure (1996, Psychopharmacology, 128(2), 161–170) to obtain data on temporal discounting of an aversive consequence, with rats as experimental subjects. In the first phase of the procedure, rats chose between one-pellet and four-pellet alternatives; when subjects developed preference for the larger-amount alternative, a shock was added to it, resulting in a loss of preference. In the first experimental condition, the delay to shock was progressively increased within each session from zero to 40 s (ascending delays), which resulted in a recovery of the preference for the larger-amount + shock alternative as the delay to shock was increased. In a subsequent condition (descending delays) the delay to shock was progressively decreased within each session, from 40 to 0 s. In both conditions, the preference for the smaller-amount no-shock alternative was well described by a hyperbolic function. The order of presentation of the delays within the session, ascending or descending, did not alter the relationship between preference and delay to shock. The temporal discounting curve obtained in the present study could represent a baseline for analyzing the impact that diverse environmental and pharmacological variables have on the temporal discounting of aversive consequences. 相似文献

Acrobatic gymnasts need excellent balance control to execute pyramids where one gymnast is supported by another. The objectives of this study were: (1) to describe balance performance by assessing the centre of pressure displacement in a group of acrobatic gymnasts executing pyramids; (2) to determine the relationship between the parameters describing the centre of pressure oscillations and pyramid score; and (3) to examine the role of each foot in providing a solid base of support to maintain the balance of the pyramid. Sixteen acrobatic gymnasts grouped in pairs performed a Half pyramid and a Straddle pyramid held for 7 s on two force platforms. Path length, variance, range trajectory, and surface area of the centre of pressure of each foot were examined to analyse the balance of the pyramid. The path length was correlated with the pyramid score (Straddle: p = 0.692 [large]; Half: p = 0.407 [moderate]). There were differences in the functions of each leg to maintain balance, with the non-preferred leg supporting a higher weight of the pyramid while the preferred leg performed control movements to maintain balance. The results suggested that quantitative analysis of balance can provide important information on pyramid performance. 相似文献

ABSTRACTSince the new millennium, the issue of financial inclusion of young people has increasingly gained recognition, especially in relation to those living in deprived circumstances. Financial inclusion can be promoted through education that specifically aims for the strengthening of young persons’ financial capabilities. In 2013, a participatory action research project was started in a rural region of Colombia to improve the research capacity of a local university through the development and implementation of a demonstration project on the financial inclusion of young people. University teachers, students and employees of a financial cooperative were trained in conducting qualitative methods with a specific aim of being responsive to the life stories of their interviewees. This paper shares the experiences from an international team of educational scholars who aim for the democratisation of research capacity and the dissemination of localised knowledge. This is done by working closely together with stakeholders and ultimately giving a voice to youth employed in the informal economy as they are usually the ones being most deprived from access to financial services. 相似文献

ResumenSe estudiaron los procesos fonémicos de decodificación y codificación en relaáón a la comprensión lectora en una muestra de 49 disléxicos de 10 a 12 años, comparándolos con un grupo de 32 lectores normales, pareados por edad, curso y nivel socio-económico. Todos los niños tenían un CI normal y se les aplicó cuatro tests verbales estandarizados, más tareas experimentales de percepción, discriminación e integración auditivo-fonémica y de comprensión.Se pudo delimitar, dentro de los disléxicos, un subgrupo de ellos con un rendimiento inferior en decodificación de pseudo-palabras, perceptión auditivo-fonémica, comprensión verbal oral y comprensión lectora silenciosa, lo que confirmó la hipótesis principal del estudio. Las diferencias entre disléxicos y lectores normales también fueron significativas. Los procesos fonémicos más estrechamente relaáonados con lectura y deletreo de pseudopalabras fueron discriminación auditiva de palabras similares e inversión oral de secuencias de letras CVC (trigramas). Esta investigación forma parte de un estudio de seguimiento. 相似文献

Visualization and mapping techniques can build a dynamic picture of information practices, including action research, within libraries, raising awareness of how the information landscape at each library may both support and retard research into the library's information practices. These techniques have implications for researchers as they generate richer data than interview or survey techniques, or methods that only take one “snapshot” of the state of practice. The data are also available to participants immediately, thus, allow for co-operative inquiry to take place in the library. Examples are offered from a project under way in two Norwegian academic libraries. 相似文献

We present a low cost microfluidic chip integrating 3D micro-chambers for the capture and the
analysis of cells. This device has a simple design and a small footprint. It allows the
implementation of standard biological protocols in a chip format with low volume consumption. The
manufacturing process relies on hot-embossing of cyclo olefin copolymer, allowing the development of
a low cost and robust device. A 3D design of microchannels was used to induce high flow velocity
contrasts in the device and provide a selective immobilization. In narrow distribution channels, the
liquid velocity induces a shear stress that overcomes adhesion forces and prevents cell
immobilization or clogging. In large 3D chambers, the liquid velocity drops down below the threshold
for cell attachment. The devices can be operated in a large range of input pressures and can even be
handled manually using simple syringe or micropipette. Even at high flow injection rates, the 3D
structures protect the captured cell from shear stress. To validate the performances of our device,
we implemented immuno-fluorescence labeling and Fluorescence in Situ Hybridization
(FISH) analysis on cancer cell lines and on a patient pleural effusion sample. FISH is a Food and
Drug Administration approved cancer diagnostic technique that provides quantitative information
about gene and chromosome aberration at the single cell level. It is usually considered as a long
and fastidious test in medical diagnosis. This process can be easily implanted in our platform, and
high resolution fluorescence imaging can be performed with reduced time and computer intensiveness.
These results demonstrate the potential of this chip as a low cost, robust, and versatile tool
adapted to complex and demanding protocols for medical diagnosis. 相似文献
