Research on media success factors is a fragmented field. Definitions, measures, and methods vary, and findings are often inconsistent. In an attempt to fill this perceived research gap, we distilled generic success factors of media products from the literature. Guided by theory and empirical findings, these factors were aggregated to complex concepts, building blocks of success that we further investigated in an exploratory qualitative study. We found that the building blocks are applicable to all types of media, independent of seriality and content types of media products. Subsequently the research question of this article is: Which building blocks of success are most important for media products? To answer this question, we conducted an online survey of 255 media professionals in print, audio-visual, and online media in Austria, Germany and Switzerland. To analyze our data, we deployed qualitative comparative analysis, a method based on set theory that is suitable to investigate complex causality. We conclude that four building blocks are necessary for success: “good” distribution, environmental orientation, form/design, and human resources are preconditions for achieving success in terms of audience market share. In addition, three patterns emerge in the sufficient paths (combinations of building blocks) to success. Which route to success a media product shows can be related to the width of its topical scope and the corresponding projected audience size.  相似文献

External support by a local coordinating agency facilitates the work of school-to-school networks. This study provides an innovative theoretical framework to analyse how support provided by local education offices for school-to-school networks is perceived by the participating teachers. Based on a quantitative survey and qualitative interview data from a networking project in eight German districts, we argue that in order to enable networks to work independently on innovative reforms, local coordinating agencies should focus on autonomy support, such as training on network management, and on support aimed at establishing significance, i.e. through vision and goal setting.  相似文献

Scientific reasoning skills are not just for researchers, they are also increasingly relevant for making informed decisions in our everyday lives. How can these skills be facilitated? The current state of research on supporting scientific reasoning includes intervention studies but lacks an integrated analysis of the approaches to foster scientific reasoning in primary through secondary education. This meta-analysis evaluates effect sizes taken from 30 interventions in experimental and quasi-experimental studies and shows a medium mean effect of interventions on scientific reasoning. Interventions successfully facilitate scientific discovery, scientific argumentation, or nature of science in all age groups. Moderator analyses show that interventions set in constructive and interactive learning activities yield positive effects but do not differ substantially. Although the meta-analysis is limited by the number of studies included, we can conclude that scientific reasoning can successfully be facilitated and we show which characteristics are beneficial in educational interventions.  相似文献

The purpose of this paper is to show how curricular quality is related to the day‐to‐day activities experienced by children and the pedagogical activities of staff, both coded through systematic target‐child observations. Data were drawn from the Effective Provision of Pre‐School Education (EPPE) and the Researching Effective Pedagogy in the Early Years (REPEY) studies. Curricular quality was measured by coding the ECERS‐E, an English curricular extension to the well‐known ECERS‐R. In centres scoring high on the ECERS‐E, staff engaged in pedagogical practices that included more ‘sustained shared thinking’ and more ‘direct teaching’ such as questioning or modelling. In high‐scoring centres, children were also observed participating in more activities associated with early reading, emergent writing and active listening. Children in centres assessed as ‘adequate’ spent more time in activities associated with the ‘Physical Development’ and ‘Creative’ curriculum. Thus the ECERS‐E gives higher scores to pedagogical practices and activities where staff take a more active role in children’s learning, including scaffolding young children’s play, especially in the communication and literacy domains of the curriculum.  相似文献

Obwohl heute ein weitgehender Konsens darüber vorliegt, dass der Qualit?tssicherung bei Humandienstleistungen ein ganz besonderer Stellenwert zukommt, fehlt eine systematische Auseinandersetzung mit den Gründen und M?glichkeiten einer solchen Qualit?tssicherung. Am Beispiel der Bildung, Erziehung und Betreuung von Kindern in Kindertageseinrichtungen sollen deshalb in diesem Beitrag systematische überlegungen zu einer Qualit?tssicherung zusammengetragen und diskutiert werden. In einem ersten Teil des Beitrags werden prim?r aus ?konomischer, jedoch auch aus p?dagogischer Perspektive die unterschiedlichen Gründe für eine Qualit?tssicherung au?erhalb des Marktes dargelegt. Eine solche Qualit?tssicherung muss jedoch nicht vom Staat selbst übernommen werden, vielmehr hat dieser lediglich die Rahmenbedingungen für ein funktionierendes Qualit?tssicherungssystem zu setzen. Der Beitrag stellt dar, welche Anforderungen ein solches Qualit?tssicherungssystem prinzipiell erfüllen muss, im Anschluss daran wird überprüft, inwiefern diese Anforderungen im deutschen Kindertageseinrichtungsbereich erfüllt sind. Als Ergebnis kann festgehalten werden, dass das deutsche Qualit?tssicherungssystem zu keinen ausreichenden Ergebnissen führt und daher reformbedürftig ist. Als Ansatzpunkt für solche Reformüberlegungen schlagen wir ein Gütesiegelsystem vor, das — in Kombination mit einer Subjektf?rderung über Kinderbetreuungsgutscheine — wettbewerbliche Elemente nicht nur bei der Zuteilung von Finanzmitteln, sondern auch bei der Qualit?tssicherung nutzbar macht. Damit verspricht das Gütesiegelsystem im Vergleich zum bisherigen System effizienter und effektiver zu sein.  相似文献

Socio-economic status during childhood has been shown to be a strong predictor of adult health outcome. Therefore, we examined associations of parental educational level, household income and migrant background with physical fitness, spinal flexibility, spinal posture as well as retinal vessel diameters in children of an urban Swiss region. A total of 358 first graders of the Swiss canton Basel-Stadt (age: 7.3, SD: 0.4) were examined. Physical fitness (20 m shuttle run test, 20 m sprint, jumping sidewards and balancing backwards), spinal flexibility and spinal posture (MediMouse®, Idiag, Fehraltdorf, Switzerland) and retinal microcirculation (Static Retinal Vessel Analyzer, Imedos Systems UG, Jena, Germany) were assessed. Parental education, household income, migrant background and activity behaviour were evaluated with a questionnaire. Parental education was associated with child aerobic fitness (P = 0.03) and screen time (P < 0.001). Household income was associated with jumping sidewards (P = 0.009), balancing backwards (P = 0.03) and sports club participation (P = 0.02). Migrant background was associated with BMI (P = 0.001), body fat (P = 0.03), aerobic fitness (P = 0.007), time spent playing outdoors (P < 0.001) and screen time (P < 0.001). For spinal flexibility and retinal vessel diameter, no associations were found (0.06 < P < 0.8). Low parental education, low household income and a migrant background are associated with poor physical fitness, higher BMI and body fat percentage and low-activity behaviour.  相似文献

This article deals with the investigation of the psychometric quality and constructs validity of algebra word problems generated by means of a schema-based version of the automatic min–max approach. Based on review of the research literature in algebra word problem solving and automatic item generation this new approach is introduced as a theory-based top–down method of automatic item generation featuring a quality control framework aimed to minimize the construct unrelated variance in the item parameters. The first study deals with the evaluation of an initial set of items. The results are replicated in the second study using a larger item set which also allows the investigation of the construct representation of the generated item. Since construct unrelated variance components (e.g. reading comprehension) have been controlled for in the item generation phase the results revealed some interesting insights into the cognitive processes of the actual mathematization phase of algebra word problem solving. The third study investigated the nomothetic span is using hierarchical confirmatory factor analysis. The results argue for the convergent and discriminant validity of the automatically generated items. Taken together, the results indicate that the automatic generation of construct valid algebra word problems at a high psychometric level is viable. The discussion is thus concerned with the implications of this new approach to item generation for theory development and evaluation as well as practical benefits for educational assessment and the development of intelligent tutoring systems.  相似文献
