Replikationsdaten für: Effects of Enactment in Virtual Reality – A Comparative Experiment on Memory for Action
No full textVirtual Reality (VR) is predicted to be a promising learning medium, especially for actions by enabling learning by enactment. Learning by enactment is based on the enactment effect, which assumes that learning by enactment leads to better memory performance than learning without enactment. To date little is known about whether the enactment effect appears in VR like in real reality. The study takes up this topic as a first research question and additionally explores in a second research question to what extent the memory performance of learning by enactment in VR can be compared to learning by enactment in real reality. We conducted a VR-experiment with four groups (n=112) that differed in terms of learning condition or environment. Participants were asked to remember short actions for a later memory test. The results indicate that learning by enactment in VR outperforms passive verbal learning in VR but does not exceed observational learning in VR. Furthermore, the results demonstrate that the memory performance of learning by enactment in VR is similar to the learning by enactment in real reality. These findings are highly relevant as the potential of VR as a new learning medium supporting learning by enactment has been demonstrated
Replikationsdaten für: Learning Transfer from Virtual Reality to Real Reality – An Experimental Study on Learning by Doing as a Learning Principle
No full textImmersive Virtual Reality (IVR) has emerged as a powerful training medium, offering unique attributes for imparting motor skills. In this context, IVR enables learning by doing - a learning principle that makes use of the interactive nature of IVR by allowing learners to actively perform movements and action sequences. This study explores the effects of learning by doing in IVR in contrast to observational learning in IVR on short-term and long-term task performance in real reality. Moreover, to better understand mechanisms behind these effects, the study investigates the role of cognitive load and enjoyment in this regard. In an IVR experiment two groups of participants were asked to learn an action sequence in IVR, either by observation or by doing, which was to be demonstrated immediately after the experiment and approximately two weeks later. Surprisingly, no superiority of learning by doing over learning by observation emerged in terms of short-term and long-term task performance to reality, but tendencies of a higher long-term task performance in the learning by doing condition are evident. Despite the higher enjoyment associated with learning by doing, it did not mediate the relationship between learning by doing and learning outcomes. Notably, learning by doing did not result in higher germane cognitive load, and mediations in this context showed no evidence for an indirect effect. These findings are highly relevant as they show slightly discernible advantages of learning by doing and at the same time highlight the relevance of further research
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
