Explaining the modality effect in multimedia learning: Is it due to a lack of temporal contiguity with written text and pictures?     

Anne Schüler  Katharina Scheiter 《Learning and Instruction》2012,22(2):92-102

The study examined whether the modality effect is caused by either high visuo-spatial load or a lack of temporal contiguity when processing written text and pictures. Students (N = 147) viewed pictures on the development of tornados, which were accompanied by either spoken or written explanations presented simultaneously with, before, or after the pictures. For verbal recall no modality effect was observed, whereas for transfer the influence of modality varied as a function of phonological working memory capacity. For pictorial recall the results showed a modality effect that was limited to simultaneous presentation, apparently in line with the temporal contiguity explanation. However, spoken simultaneous presentations were not superior to spoken sequential presentations, which contradicts the temporal contiguity explanation for the modality effect. Rather, it seems as if learners with simultaneous presentation of written text and picture concentrated more on the text and ignored the pictures, resulting in worse pictorial recall.  相似文献   

Media Logic and Political Logic Online and Offline     

Jörg Haßler 《Journalism Practice》2014,8(3):326-341

One aspect of the mediatization of politics is the idea that political actors adapt to the communication logic of news media to gain, for example, news media attention. Currently, this process may be influenced by the diffusion of the internet as a political communication channel, especially because online communication provides a new opportunity for political actors to communicate directly with citizens. Thus far, the adaptation to media logic by political parties has mainly been examined in the context of election campaigns. In order to transfer these findings to regular political communication, this study compares the use of media logic in the mass media and in direct political communication channels online and offline about the United Nations Climate Change Conferences 2011 and 2012. A quantitative content analysis of the conference protocols (input) and the presentation of the conference results in the seven most frequently used German offline news outlets (print and TV) and their online counterparts, as well as political offline and online communication channels like parliamentary speeches and websites of the six parties represented in the German parliament (output), was conducted. Results show that in the context of regular political communication, political actors seem to follow media logic to a lesser extent than in the context of election campaigns. Thus far, the influence of online communication on the mediatization of politics seems to be rather marginal. The causes and consequences of these findings are discussed.  相似文献

Cognitive preconditions of early reading and spelling: a latent-variable approach with longitudinal data     

Anna-Lena Preßler  Tanja Könen  Marcus Hasselhorn  Kristin Krajewski 《Reading and writing》2014,27(2):383-406

The aim of the present study was to empirically disentangle the interdependencies of the impact of nonverbal intelligence, working memory capacities, and phonological processing skills on early reading decoding and spelling within a latent variable approach. In a sample of 127 children, these cognitive preconditions were assessed before the onset of formal education, whereas reading as well as spelling achievement was measured at the end of grade 1. The findings indicate that working memory does contribute to the prediction of early reading and spelling, and that this contribution outperforms that of general intelligence and phonological recoding from long-term memory during the early steps of reading and spelling acquisition. Moreover, the results show that phonological awareness mediates the effects of working memory capacities on early literacy outcomes. The role of working memory and phonological awareness as key cognitive preconditions of early reading and spelling are discussed.  相似文献   

Detecting Multidimensional DIF in Polytomous Items with IRT Methods and Estimation Approaches     

Güler Yavuz Temel 《Journal of Educational Measurement》2024,61(1):69-98

The purpose of this study was to investigate multidimensional DIF with a simple and nonsimple structure in the context of multidimensional Graded Response Model (MGRM). This study examined and compared the performance of the IRT-LR and Wald test using MML-EM and MHRM estimation approaches with different test factors and test structures in simulation studies and applying real data sets. When the test structure included two dimensions, the IRT-LR (MML-EM) generally performed better than the Wald test and provided higher power rates. If the test included three dimensions, the methods provided similar performance in DIF detection. In contrast to these results, when the number of dimensions in the test was four, MML-EM estimation completely lost precision in estimating the nonuniform DIF, even with large sample sizes. The Wald with MHRM estimation approaches outperformed the Wald test (MML-EM) and IRT-LR (MML-EM). The Wald test had higher power rate and acceptable type I error rates for nonuniform DIF with the MHRM estimation approach.The small and/or unbalanced sample sizes, small DIF magnitudes, unequal ability distributions between groups, number of dimensions, estimation methods and test structure were evaluated as important test factors for detecting multidimensional DIF.  相似文献   

Internet in the Classroom: Effects on Reading Comprehension,Motivation and Metacognitive Awareness     

Carina Weinmann  Charlotte Löb  Tamara Mattheiß 《Educational Media International》2013,50(3):149-161

This study examined the potential of entertainment-education (E-E) for promoting engagement with a science issue. It was assumed that certain entertaining features of a media experience increase viewers’ perceived knowledge about an issue. Drawing on different theoretical models of E-E and on persuasive effects of narrative media messages, three hypotheses and one research question were assessed in a survey among 103 participants, who were shown a movie about genetic engineering beforehand. Results suggested that the higher viewers’ transportation, identification, and enjoyment were, the more they actually felt informed. Viewers’ degree of transportation, though, revealed to be sufficient to explain their perceived knowledge.  相似文献   

A new instrument for measuring pre-service biology teachers' pedagogical content knowledge: The PCK-IBI     

Jörg Großschedl  Virginia Welter  Ute Harms 《科学教学研究杂志》2019,56(4):402-439

Teachers' pedagogical content knowledge (PCK) is highly important for effective design and implementation of school teaching. Thus, the current status, development and efficacy of this knowledge, its relationships with teaching quality parameters, and its impact on students' learning processes and success, require rigorous examination. Thoroughly validated, objective and reliable test instruments that are highly sensitive to changes in variables of proven knowledge-related relevance in teacher education are also required. Previous attempts to design such instruments for assessing science teachers' PCK have largely focused on mathematical content. Therefore, here we present an instrument (the pedagogical content knowledge in biology inventory, PCK-IBI), based on conceptualizations of teachers' professional competence, for assessing secondary school pre-service biology teachers' PCK. In a series of three evaluations and refinements it was tested with samples of N = 274 and N = 432 German pre-service as well as one sample of n = 65 German pre-service and n = 35 German in-service biology teachers. Item analysis, scale analysis and empirically obtained indicators of validity suggest that the final 34-item-version of the PCK-IBI is unidimensional, provides objective test scores and enables reliable and valid registration of pre-service biology teachers' PCK. Thus, hypotheses regarding specific aspects of the model on which the PCK-IBI's construction is based on are empirically supported. The results of our study provide empirical support for the instrument's potential utility.  相似文献   

Wider die „Sternchenkunde“!     

Dirk Büsch  Bernd Strauß 《Sportwissenschaft》2016,46(2):53-59

In general, empirical results are analyzed using statistical methods to examine and discuss differences and interrelationships. Statistical methodological evaluation and the underlying reporting strategy can be described as a technical language that has to be learnt for successful communication between researchers, authors and reviewers; however, empirical science is a constantly changing environment which is why the statistical methods applied have to be refined to adhere to new empirical approaches. This line of thought will be discussed in this article and five essential recommendations will be presented: (a) directionality of hypotheses, (b) confidence intervals, (c) effect sizes, (d) confidence intervals of effect sizes and (e) practical meaningfulness.  相似文献   

(N)Olympia in Germany? An analysis of the referendum against Munich 2022     

Thomas Könecke  Mathias Schubert  Holger Preuß 《Sportwissenschaft》2016,46(1):15-24

In November 2013, local citizens of Munich and the surrounding districts voted in a referendum against a city’s bid for the 2022 Winter Olympic Games. Since this is but one example of such a failed referendum—others being the ones in Poland, Switzerland and Austria—it is astonishing that it seems to become common practice to conduct public polls regarding the bid for a mega sport event. The city of Hamburg, for instance, will be the next German city to hold a referendum on its bid for the 2024 Olympic Games in November 2015. Against this backdrop, we introduce the ‘Arenatheoretical Model’ into mega event research and conduct a qualitative content analysis of the media coverage on the Munich referendum. Three nationwide German newspapers were analysed as the model suggests that this coverage has a profound influence on the public opinion in other parts of the country. The aim was to identify arguments brought forward to explain the outcome of the referendum. Besides a number of other issues, such as concerns regarding event legacy and regional matters, major findings stress the significance of a damaged brand image of international sport organisations and ‘their’ events. Based on these insights, a number of implications can be derived for other cities/nations and sport organisations that depend on a favourable public opinion in their efforts to stage a mega sport event.  相似文献
