Publikation Towards hybrid dialog management strategies for a health coach chatbot(2023) Pande, Charuta; Martin, Andreas; Pimmer, ChristophWe present an iterative and incremental approach to designing dialog management for a health coach chatbot based on our in-progress research. The requirements are derived from the coaching needs of young people living with HIV. We identify a hybrid dialog management approach to address different coaching needs as well as dialog acts to enable smooth conversations. In addition, relevant technical components were identified to be integrated into the dialogs to improve user experience.04B - Beitrag KonferenzschriftPublikation The role of gamification in the development of (fake) news literacy in higher education(IATED, 2023) Jäger, Janine; Eisemann, Christoph; Pimmer, Christoph; Gómez Chova, Luis; González Martínez, Chelo; Lees, JoannaFake news has become a major societal concern, particularly in the online and social media sphere. Higher education institutions have an important role to play in fostering critical thinking and promoting media and news literacy. Therefore, educators need to explore effective and innovative ways to teach news literacy. Online games have emerged as a potentially promising tool. Against this background, the paper presents a framework that conceptualises competences relevant for news literacy and 'fake' news literacy. It then uses the framework to conduct an evaluation of 17 popular and freely available online games about misinformation and disinformation and their suitability for developing competences relevant to (fake) news literacy in a higher education context. The findings indicate that the games were generally limited in scope and covered only specific news literacy competence areas. The paper discusses the results of the analysis and develops some suggestions for the integration of games in the higher education landscape.04B - Beitrag KonferenzschriftPublikation WhatsApp for mobile learning. Effects on knowledge, resilience and isolation in the school-to-work transition(Elsevier, 2021) Pimmer, Christoph; Brühlmann, Florian; Odetola, Titilayo Dorothy; Dipeolu, Oluwafemi; Oluwasola, Olusola; Jäger, Janine; Ajuwon, Ademola JohnsonThis experimental study investigated the use of instant messaging in the school-to-work transi-tion, a crucial stage of learning and development. Newly graduated health professionals (n=235) participated in WhatsApp groups in which moderators shared knowledge and stimulated professional discussions. The results show that participants in the WhatsApp groups had markedly higher levels of knowledge, greater resilience as well as lower levels of professional isolation– in comparison with the control group. They also reported less stress when searching for a new job These findings are affirmed by the qualitative analysis of open survey questions: knowledge ac-quisition emerged as the main benefit followed by connectedness and professional informational benefits. A further interesting result is that the general, day-to-day use of WhatsApp outside of the intervention was linked to higher levels of resilience. Another finding is that although the actual (measured) and self-reported frequency of participation in the WhatsApp groups correlated highly, these measures did not predict the outcome variables in the regression analysis. This observation questions the frequency of participation as a proxy for the success of engagement.01A - Beitrag in wissenschaftlicher ZeitschriftPublikation Educational Approaches to Adress Fake News(IADIS Press, 2021) Eisemann, Christoph; Pimmer, Christoph; Sampson, Demetrios G.; Ifenthaler, Dirk; Pedro, IsaíasFake and false news, an unfortunate hallmark of today's information society, have serious political and societal consequences. Little systematic knowledge is available about effective learning, teaching and awareness-raising strategies that help users in addressing fake news. This study reports preliminary results from a systematic literature review aimed at systematising different approaches and determining their effectiveness. Three main approaches emerged in the analysis: Firstly, the findings suggest that strategies to correct existing misconceptions caused by fake news have limited effectiveness and can be even counterproductive, particularly for polarising topics. Secondly, the evidence on the effectiveness of training on fake news detection methods is encouraging but inconclusive. Thirdly, despite the common perception that fake news detection needs to be linked to an understanding of the economic, ideological and cultural dimensions of media systems, the few empirical studies found in this area did little to support this claim. A tentative conclusion from these findings is the need to integrate education on false news and training on fake news detection strategies in educational programmes as early as children's media consumption starts.04B - Beitrag KonferenzschriftPublikation Fake News Resilience through Online Games? Tentative Findings from a Randomized Controlled Trial in Higher Education(IADIS Press, 2021) Eisemann, Christoph; Pimmer, Christoph; Mateescu, Magdalena; Demetrios, G. Sampson; Ifenthaler, Dirk; Isaías, PedroLearners’ cognitive abilities to assess the credibility of information in digital spaces are a relevant part of 21st century skills. Emerging evidence suggests that gamification could be a suitable approach for learners to develop these skills independently of their educational level. This study examined two popular online fake news games in a higher education setting using a randomized controlled trial. 72 students were randomly assigned to one of two games. Their ability to classify news, i.e. to distinguish fake news from correct news, was tested before and after playing the game. The results from multiple regression analysis suggest that there was only a very modest increase in participants’ news classification abilities in one game and no improvement in the other game. Contrary to some prior literature, these preliminary findings provide no evidence for the use of gamification in developing students’ fake news resilience in higher education contexts and they call for more nuanced education and gamification approaches.04B - Beitrag KonferenzschriftPublikation WhatsApp community of practice for nurse graduates in South Africa(Elsevier, 2020) Ologun-Abiodun, Rita; Daniels, Felicity; Pimmer, Christoph; Chipps, Jennifer01A - Beitrag in wissenschaftlicher ZeitschriftPublikation Educational approaches to address fake news.

A qualitative systematic review of South Africa’s community service programme(Democratic Nursing Organisation of South Africa, 2019) Ologun-Abiodun, Rita; Daniels, Felicity; Pimmer, Christoph; Chipps, JenniferBackground: The student-to-nurse graduate transition is a pivotal phase in the professional development of nurses. In South Africa, this transition is part of a compulsory community service programme, which requires newly graduated nurses to work in rural and/or underserved areas for a period of 1 year. Objectives: The aim of this study was to review nurse graduates’ experiences and support needs during their transition in the compulsory community service programme. Methods: A qualitative systematic review of experiences was conducted. Qualitative research studies that addressed nurses’ experience in South Africa (2008–2017) were identified in Cochrane, Joanna Briggs Institute (JBI), Academic Search Complete, CINAHL, PubMed, SABINET, Science Direct, SCOPUS and Google Scholar databases. The systematic review methods included searching, sifting, abstracting and quality assessment of relevant qualitative studies by two reviewers and cross-checking by a third reviewer. Two reviewers independently performed blinded data extraction and quality assessment using the confidence in qualitative synthesis findings (ConQual) approach. Results: A total of 1257 studies were identified of which 12 met the inclusion criteria. Seven of the 12 studies were published articles and six were theses. The quality of the studies was found to be of high standard based on the ConQual rating. Four main themes emerged from the analysis: (1) rich developmental experiences through practice exposure, (2) difficulties in reconciling theory and practice, (3) contextual challenges in the workplace and (4) need for professional support structures, educational measures and public guidelines. Conclusion: Although positive experiences were reported, various challenges emerged, indicating the need for more systematic support mechanisms during transition.01A - Beitrag in wissenschaftlicher ZeitschriftPublikation Collaboration on large interactive displays: A systematic review(Taylor & Francis, 2019) Mateescu, Magdalena; Pimmer, Christoph; Zahn, Carmen; Klinkhammer, Daniel; Reiterer, HaraldLarge Interactive Displays (LIDs), such as tabletops or interactive walls, are promising innovations, which are increasingly used to support co-located collaboration. Yet the current evidence base on the impact of LID use on collaborative processes and outcomes, and associated influencing factors, is fragmented, particularly in comparison with other media. To address this gap, a systematic review was carried out in the databases Web of Science, Psych.Info, ACM, Elsevier, JSTOR and Springer and in the ACM CHI conference database. A corpus of 38 articles with experimental study designs met the eligibility criteria and was analyzed in-depth. With regard to collaboration processes, the findings suggest a relatively clear advantage of the use of LIDs over classic forms of collaboration, in particular over single-user environments (e.g. laptops). With attention to collaborative outcomes, positive effects of LIDs were identified for knowledge gains and social encounters, and mixed effects for task-related outcomes. The analysis further shows relevant influencing factors of LID, such as the separation of personal and joint work spaces and the deployment of horizontal instead of vertical displays. Conceptual and practice implications are discussed.01A - Beitrag in wissenschaftlicher ZeitschriftPublikation Collaboration on large interactive displays: a systematic review(Taylor & Francis, 2019) Zahn, Carmen; Mateescu, Magdalena; Pimmer, Christoph; Klinkhammer, Daniel; Reiterer, HaraldLarge Interactive Displays (LIDs), such as tabletops or interactive walls, are promising innovations, which are increasingly used to support co-located collaboration.
