Es gibt einige Hinweise darauf, dass Vorstellungen vom Lehren und Lernen sowohl für das Handeln der Lehrkr?fte im Unterricht
als auch für Zielkriterien auf der Ebene der Schüler eine Rolle spielen. Dabei gelten konstruktivistisch orientierte Sichtweisen
als besonders günstig. Empirische Untersuchungen dazu gibt es jedoch bislang nur auf einzelne fachdidaktische Inhaltsbereiche
bezogen. In der vorliegenden Studie werden konstruktivistisch orientierte Lehrereinstellungen mit Merkmalen des Unterrichts
(?ffnung des Unterrichts im Hinblick auf Entscheidungsm?glichkeiten für Schüler/-innen und Strukturierung des Unterrichts)
sowie mit Einsch?tzungen der Schüler/-innen (Selbstbestimmungsempfinden und Interessantheit des Unterrichts) in Beziehung
gesetzt. Die Ergebnisse best?tigen die Theorie: In den Klassen der Lehrer/-innen mit überwiegend konstruktivistischen Vorstellungen
von Lernen und Lehren gibt es mehr Freir?ume, ohne dass der Unterricht weniger strukturiert abl?uft. Zudem empfinden sich
die Schüler/-innen als selbstbestimmter und sch?tzen den Unterricht als interes-santer ein. 相似文献

This introductory essay reviews the key contributions of David Teece's landmark paper “Profiting from Innovation” published in research policy in 1986. It summarises the contributions of each of the papers in the special issue. It then offers some perspectives on the key themes emerging from these papers, and on the broader challenges facing researchers, strategists and policymakers in the field of technology innovation today. 相似文献

Although the principle of holography was conceived as long ago as 1947, interest was limited until the advent of the laser in 1960 made possible the off-axis holography widely used today. Since then holography has found many applications and become so well known outside the laboratory as to be a recognized art form. Within the last few years considerable progress has also been made in acoustic holography. 相似文献

Providing test questions after an initial study phase is a common instructional technique. In theory, questions that require higher-level (deep) processing should be more beneficial than those that require lower-level (shallow) processing. However, empirical evidence on the matter is inconsistent. To shed light on two potential reasons for these inconsistencies, we conducted an experiment (N = 81) to analyze the role of (a) the share of information to which test questions direct learners and (b) the learning activities performed in the initial study phase with respect to the effects between higher- and lower-level test questions. We found that both the share of focused information and the initial learning activities moderated the effects between higher- and lower-level test questions. 相似文献

In March 2013, after six years of consultation, an Australian Labor government launched the national cultural policy document, Creative Australia. In July 2013, a Coalition government was elected, Senator George Brandis became Minister for the Arts, and the policy was dumped. With it went cross-party consensus about funding rationales and measurement strategies, with disastrous consequences for the cultural sector. This cautionary tale of gaffes, pay-back and abrupt changes of direction, highlights the fragility of policy memory that condemns artists and arts managers to a never-ending reinvention of the evidentiary wheel. Our paper examines the problem of collective understanding (“world”) in cultural policy-making in Australia, exacerbated not only by the short-term electoral cycles which undermine long-term cultural outcome timescales, but by a fixation on what Hannah Arendt calls “the peculiar and ingenious replacement of common sense with strict logicality”. Evidence of value is only meaningful when it occurs in a policy memory that can fully avow it and respond in appropriate ways. Measurement methods are over-determined by epistemology and by experience. We argue that the balance between these determinants of effective cultural policy-making has been lost. An emphasis on numerical data – especially economic data – has forced arguments for culture into a decontextualised register of quantitative proof. Recent events in Australia suggest that different, more direct ways of engaging with cultural policy-making are required for the problem of collective understanding to be successfully assayed. 相似文献

The current study compared changes in neuromuscular control between slackline training and the stabilization training elements of the FIFA 11+ programme. Twenty-five students in 2 groups performed a 12-unit training programme. The slackline training group (n?=?13) exclusively trained with a slackline. The stabilization training group (n?=?12) practised exercises as described in the second part of the FIFA 11+ programme. Improvements in balance were assessed using three tests for dynamic, quasi-static, and perturbed postural control: the star excursion balance test (SEBT), the closed-eye single-leg stance, and the MFT S3-Check. Both groups significantly improved the stability and sensorimotor index of the MFT S3-Check (p?<?.001), their range on the SEBT (p?<?.001), and the duration of closed-eye single-leg stance (p?<?.001). The group?×?training interaction was significant for the MFT S3-Check (stability index: p?=?.042; sensorimotor index: p?=?.004) and the SEBT (dominant leg: p?=?.003; averaged both legs: p?=?.016), with the slackline training group showing a larger training effect than the stabilization training group. The results of the present study suggest that slackline training offers similar – or better – improvements in neuromuscular control as the FIFA 11+ warm-up programme. If compliance with the FIFA 11+ programme is declining, then slacklining might offer an alternative approach to reach the training goals of improved sensorimotor control. 相似文献
