- PublikationGamification of electronic learning in radiology education to improve diagnostic confidence and reduce error rates(American Roentgen Ray Society, 2020) Winkel, David J.; Brantner, Philipp; Lutz, Jonas; Korkut, Safak; Linxen, Sebastian; Heye, Tobias [in: American Journal of Roentgenology]OBJECTIVE. The purpose of this study is to validate an electronic learning, or e-learning, concept featuring gamification elements, rapid case reading, and instant feedback. SUBJECTS AND METHODS. An e-learning concept was devised that offered game levels for the purpose of providing training in the detection of pneumothorax in 195 cases, with questions read in rapid succession and instant feedback provided for each case. The user's task was to locate the pneumothorax on chest radiographs and indicate its presence by clicking a mouse. The game level design included an entry test consisting of 15 cases, training levels with increasing difficulty that involved 150 cases, and a final test that including 30 cases (the 15 cases from the entry test plus 15 new cases). A total of 126 candidates were invited via e-mail to participate and were asked to complete a survey before and after playing the game, which is known as RapRad. The level of diagnostic confidence and the error rate before and after playing the game were compared using a Wilcoxon signed rank test. RESULTS. Fifty-nine of 126 participants (47%) responded to the first survey and finished the game. Of these 59 participants, 29 (49%) responded to the second survey after completing the game. Diagnostic confidence in pneumothorax detection improved significantly, from a mean (± SD) score of 4.3 ± 2.1 on the entry test to a final score of 7.3 ± 2.1 (p < 0.01) after playing RapRad, with the score measured on a 10-point scale, with 10 denoting the highest possible score. Of the participants, 93% indicated that they would use the game for learning purposes again, and 87% indicated that they had fun using RapRad (7% had a neutral response and 6% had a negative response). The error rate (i.e., the number of failed attempts to answer a question correctly) significantly decreased from 39% for the entry test to 22% for the final test (p < 0.01). CONCLUSION. Our e-learning concept is capable of improving diagnostic confidence, reducing error rates in training pneumothorax detection, and offering fun in interaction with the platform.01A - Beitrag in wissenschaftlicher Zeitschrift

- PublikationIs It Still Where I Expect It?—Users’ Current Expectations of Interface Elements on the Most Frequent Types of Websites(Oxford University Press, 27.08.2016) Heinz, Silvia; Linxen, Sebastian; Tuch, Alexandre Nicolas; Frasseck, Lars; Opwis, Klaus [in: Interacting with Computers]Knowing users’ expectations about what they expect on a website and where they expect to find it is crucial for the success of a website. For the last decade, technological advances have entailed major changes in website design but the impact of these changes on users’ mental representations of websites remains unclear. In an online study (N = 841), we asked users to sketch their prototypical version of an online shop, a news website and a company page, thereby indicating the interface elements they expect on the website and their expected location. We compared our results to those of a previous study to investigate changes in users’ mental representations of websites over time. This comparison suggests that interface elements such as the logo, main content and navigation area are still expected in the same location although others have shifted to the rich footer area at the bottom of the website. In addition, new elements such as links to social networks have been incorporated into users’ mental representations whereas other interface elements have disappeared. By providing updated consolidated blueprint models for all three website types, we help designers to create expectation-based websites. Further implications for research and practitioners are discussed.01A - Beitrag in wissenschaftlicher Zeitschrift

- PublikationInformal mobile learning in nurse education and practice in remote areas. A case study from rural South Africa(Elsevier, 2014) Pimmer, Christoph; Brysiewicz, Petra; Walters, Fiona; Linxen, Sebastian [in: Nurse Education Today]Background: With the proliferation of portable digital technology, mobile learning is becoming increasingly popular in nursing education and practice. Most of the research in this field has been concentrated on small-scale projects in high income countries. Very little is known about the ways in which nurses and midwives use mobile technology in remote and resource poor areas in informal learning contexts in low and middle income countries. Objectives: To address this gap, this study investigates whether nurses use mobile phones as effective educational tools in marginalized and remote areas, and if so, how and why. Setting and Methods: In rural South Africa, 16 nurses who attended an advanced midwifery education program, facilitators and clinical managers were interviewed about their use of digital mobile technology for learning. Techniques of qualitative content analysis were used to examine the data.01A - Beitrag in wissenschaftlicher Zeitschrift
- PublikationMobile learning in resource-constrained environments. A case study of medical education(Taylor & Francis, 01.12.2012) Pimmer, Christoph; Linxen, Sebastian; Gröhbiel, Urs; Kumar Jha, Anil; Burg, Günter [in: Medical Teacher]Background: The achievement of the millennium development goals may be facilitated by the use of information and communication technology in medical and health education. Aims: This study intended to explore the use and impact of educational technology in medical education in resource-constrained environments. Methods: A multiple case study was conducted in two Nepalese teaching hospitals. The data were analysed using activity theory as an analytical basis. Results: There was little evidence for formal e-learning, but the findings indicate that students and residents adopted mobile technologies, such as mobile phones and small laptops, as cultural tools for surprisingly rich "informal" learning in a very short time. These tools allowed learners to enhance (a) situated learning, by immediately connecting virtual information sources to their situated experiences; (b) cross-contextual learning by documenting situated experiences in the form of images and videos and re-using the material for later reflection and discussion; and (c) engagement with educational content in social network communities. Conclusion: By placing the students and residents at the centre of the new learning activities, this development has begun to affect the overall educational system. Leveraging these tools is closely linked to the development of broad media literacy, including awareness of ethical and privacy issues.01A - Beitrag in wissenschaftlicher Zeitschrift
