Assessing the Impact of Interactive Educational Videos and Screencasts Within Pre-clinical Microanatomy and Medical Physiology Teaching
No full textModern medical curricula adopt the use self-directed learning approaches, which frequently include the use of technology enhanced learning resources. Often, students prefer those which are available via mobile devices because it can facilitate flexibility and autonomy with their learning, more so than with traditional modalities. Although the production value of resources may be appealing to users, those that work most effectively for education align well to existing pedagogies. One such pedagogy is the cognitive theory of multimedia learning. It is a framework that can be used to facilitate the construction of educational video, that can benefit learning gain through reducing the cognitive load.Although much research has been conducted on how information should be presented in video resources, there is very limited evidence within the subject of clinical anatomy and physiology or when applying different types of educational video, such as screencasts, or interactive video. In the field of anatomy education recent approaches have sought to standardize a robust methodology to evaluate digital resources. This procedure utilizes a combination of normalized learning gain and learner perceptions to gain an accurate picture of educational impact.The current study investigated the impact of both interactive educational videos and screencasts compared with traditional teaching techniques in the challenging subjects of histology and pain physiology. A quasi-randomized, cross-sectional study was conducted with 135 medical students enrolled at the University of Southampton. Sixty fourth- and fifth-year students assessed the histology resources, and 75 second-year students assessed the pain histology resources. Participants were randomly assigned to either a text-based resource, interactive video, or screencast group. Outcomes measured were:1. Normalized knowledge gain (and retention) assessed using one-best-answer multiple choice question tests2. Student perceptions using 1–10 Likert-scale style questionnaires.A significant improvement in mean normalized knowledge gain was observed for all teaching modalities. For pain physiology, the means were: Text—49.0% (n = 23), interactive video—70.1% (n = 26), and screencast—53.8% (n = 26). For all learning gains, P < 0.001. For histology, there was a mean normalized learning gain for text—80.0% (n = 20), interactive video—74.4% (n = 20), and screencast groups—68.3% (n = 20). For all learning gains, P < 0.001.For pain physiology resources, interactive videos significantly improved learning gain compared to the screencast (P < 0.05) and the text resource groups (P < 0.01). There was no significant difference between those who used the text or screencast resources. There was also no significant difference in knowledge retention between the different teaching methods for each subject.Following teaching, all three teaching modalities had similar effects on student confidence in the subjects, desire for educational channels dedicated to each topic, and preference for locally produced vs. externally produced videos. These findings have the potential to inform educators on which types of resources to create or to select for their students to have the best impact on learning
The efficacy of interdisciplinary near-peer teaching within neuroanatomical education—preliminary observations
No full textNear-Peer Teaching (NPT) is increasingly becoming an integral part of the medical curriculum. When considered alongside the increasing popularity of interdisciplinary education, it seems appropriate to explore NPT within an interdisciplinary context. In these observations, 3rd-year medical students taught 2nd-year psychology students neuroanatomy. The session was evaluated using three objective and subjective assays. A knowledge assessment test showed significant improvement after teaching, and there were significant improvements on self-perceived knowledge/attitudes towards neuroanatomy, as well as positive feedback on the use of NPT. These observations evidence the successful use of Interdisciplinary Near-Peer Teaching (INPT) within a neuroanatomical curriculum.Supplementary Information: The online version contains supplementary material available at 10.1007/s40670-021-01238-6.</p
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
