- PublikationThe neglected grass root adoption of mobile phones as learning tools in resource-limited settings. A study from advanced midwifery education in KwaZulu-Natal, South Africa(29.06.2013) Pimmer, Christoph; Gröhbiel, Urs; Walters, Fiona; Linxen, Sebastian; Chipps, JenniferBackground/rationale: Many mhealth and mlearning interventions fail, because they adopt a techno-centric view and ignore the local context. To address this, the present study investigated the 'organic' adoption and educational usage of mobile phones by health workers in rural health settings. Methods: A qualitative study was conducted interviewing nursing/advanced midwifery students, facilitators and nursing managers from rural, resource-constrained regions in the province of KwaZulu-Natal, South Africa. Content analysis used the concepts of Community of Inquiry theory as 'a priori-constructs'. Results: The research revealed a number of unexpected learning and teaching practices - based on the grass-root adoption of mobile phone functions and in particular social apps. These practices involved cognitive, teaching and social presence as well as reflective practice and enabled rich educational experiences - according to the Community of Inquiry Theory.04B - Beitrag Konferenzschrift
- 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

- 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

- PublikationKulturelle Unterschiede bei mentalen Modellen für Webobjekte(31.03.2014) Heinz, Silvia; Linxen, SebastianWebsiten, die basierend auf den mentalen Modellen der Nutzer gestaltet wurden, sind für Nutzer leichter zu bedienen. Werden Webelemente entsprechend platziert, d.h. entsprechend den Erwartungen der Nutzer, können Fehler vermieden und die Effizienz der Interaktion mit Webseiten gesteigert werden. Bisherige Studien haben Daten über mentale Modelle verschiedener Arten von Webseiten gesammelt, jedoch stützen sich die Erkenntnisse dieser Studien auf Untersuchungen mit spezifischen Zielgruppen und berücksichtigen den Einfluss kultureller Aspekte nicht. Darüber hinaus hat sich die Gestaltung von Webseiten im Laufe der Zeit verändert und die erhobenen mentalen Modelle könnten veraltet sein. Um diese Einschränkungen zu beheben wurde eine Onlinestudie durchgeführt und die mentalen Modelle der Nutzer verschiedener Kulturen und Länder erfasst. Die Studienteilnehmer wurden gebeten, mit den gängigsten Webelementen (z.B. Navigation, Suchfeld) die Struktur einer für sie typischen Unternehmenswebseite, eines Nachrichtenportals und eines Online-Shops zu skizzieren. Diese mentalen Modelle wurden verglichen und länderspezifische sowie kulturell bedingte Unterschiede herausgearbeitet. Die Erfassung aktueller mentaler Modelle unter Berücksichtigung kultureller Unterschiede bietet die Möglichkeit, eine Vorlage für die Platzierung von Webelementen zu schaffen, die beim Design von erfolgreichen, länderspezifisch angepassten Websites zu Hilfe genommen werden kann.06 - Präsentation
- PublikationHow WEIRD is HCI?: Extending HCI Principles to Other Countries and Cultures(ACM, 2015) Sturm, Christian; Oh, Alice; Linxen, Sebastian; Abdelnour Nocera, Jose; Dray, Susan; Reinecke, Katharina [in: Proceedings of the 33rd Annual ACM Conference Extended Abstracts on Human Factors in Computing Systems]A large majority of articles published at prominent HCI venues such as CHI and CSCW reports on studies with WEIRD (Western, Educated, Industrialized, Rich, and Democratic) participants, ignoring that the results might not apply to other subject populations. This workshop aims to have the following two main outcomes: (1) A list of major principles that HCI researchers often build on and that are unlikely to apply to users in other countries and cultures. (2) An action plan that describes how we can extend these previous findings, such as by collaborating across countries and cultures, conducting large-scale online experiments, or creating a culture of replications and extensions with more diverse subject populations. Furthermore, the workshop aims to establish an interest group with the goal to improve the external validity of HCI research and to inform the design of further research studies in this area.04B - Beitrag Konferenzschrift
