abstract = {Die Nutzung von digitalen Medien zur Teilhabe an gesellschaftlichen und wirtschaftlichen Prozessen sowie die Teilhabebarrieren und die digitale Kluft sind seit dem Aufkommen der Computertechnologie ein zentrales Phänomen sozialer (Un-)Gleichheit. Dieser Artikel gilt der Untersuchung der digitalen Kluft im Zuge der Umstellung des Studienbetriebs auf „home-learning“ an den österreichischen Universitäten Anfang März 2020. Diese notwendige Umstellung der Lehre zielte auf die Verminderung der Kontaktmöglichkeiten und damit auf die Reduzierung der Ansteckungsgefahr mit COVID-19 ab. Dieser Artikel beleuchtet – auch im Sinne partizipatorischer Fragestellungen – die Herausforderungen, denen sich Studierende in Zeiten des „home-learning“ gegenübersahen, um an der digitalen Lehre teilhaben zu können. Im Rahmen der zugrundeliegenden Studie wurde untersucht, inwieweit die universitären Maßnahmen bezüglich „home-learning“ sowie weitere (nationale) Regelungen zu Teilhabebarrieren für Studierende wurden. Im Folgenden werden die Ergebnisse dieser Befragung (n=412) unter Studierenden der Bildungswissenschaft der Universität Wien zusammengefasst. Die Ergebnisse zeigen, dass nicht so sehr der technische Zugang zu Computer und Internet hinderlich ist, sondern vielmehr die Kompetenzanforderungen bestimmter Technologien, die Organisation von Tages- und Wochenabläufen sowie des eigenen Lernens und der Umgang der Lehrenden mit der Situation. Auch steigende Kursanforderungen, der Zugang zur Bibliothek, zunehmende Betreuungspflichten und der (drohende) Verlust des Arbeitsplatzes haben die Teilnahme am „home-learning“ erheblich beeinträchtigt.},

abstract = {Evaluation studies are essential for determining the utilization of technology-enhanced learning systems. Prior research often focuses on evaluating specific factors like the technology adoption or usability aspects. However, it needs to be questioned if evaluating only specific factors is appropriate in each case. The aim of this research paper is to outline which methods are suited for evaluating technology-enhanced learning systems in interdisciplinary research domains. Specifically, we focus our analysis on pedagogical conversational agents – i.e. learning systems that interact with learners using natural language. For instance, in addition to technology acceptance, further factors like learning success are more important in this case. Based on this assumption, we analyze the current state-of-the-art literature of pedagogical conversational agents to identify evaluation objectives, procedures and measuring instruments. Afterward, we use the results to propose a guideline for evaluations of pedagogical conversational agents.},

abstract = {Test anxiety is a condition in which people experience extreme distress and anxiety before and in test situations. It affects up to 40 percent of all students. Conventional treatment includes both medication and psychotherapy, but studies also demonstrated that placebos affect anxiety symptoms. Although in the traditional understanding placebos need to be administered in a concealed way, intriguing new studies report that open-label placebos can be effective. Since prescription of fake pills involves ethical problems, open-label placebos may provide important new treatment possibilities. Here we report results of a pilot study examining whether open-label placebos may reduce test anxiety and improve self-management skills. 58 students participated in a two-group randomized controlled trial. Two weeks before an exam at the university participants received open-label placebos or no pills (control group). Participant – provider relationship and amount of contact time was held similar for all groups. After two weeks we found that test anxiety and self-management abilities (skills and resources) of the open-label placebo group were more improved than in the control group. Thus, our results seems to indicate that open-label placebos may reduce test anxiety and enhance self-management skills in students.},

abstract = {The Social Sciences have long been struggling with quantitative forms of research assessment – insufficient coverage in prominent citation indices and overall lower citation counts than in STM subject areas have led to a widespread weariness regarding bibliometric evaluations among social scientists. Fueled by the rise of the social web, new hope is often placed on alternative metrics that measure the attention scholarly publications receive online, in particular on social media. But almost a decade after the coining of the term altmetrics for this new group of indicators, the uptake of the concept in the Social Sciences still seems to be low. Just like with traditional bibliometric indicators, one central problem hindering the applicability of altmetrics for the Social Sciences is the low coverage of social science publications on the respective data sources – which in the case of altmetrics are the various social media platforms on which interactions with scientific outputs can be measured. Another reason is that social scientists have strong opinions about the usefulness of metrics for research evaluation which may hinder broad acceptance of altmetrics too.
We conducted qualitative interviews and online surveys with researchers to identify the concerns which inhibit the use of social media and the utilization of metrics for research evaluation in the Social Sciences. By analyzing the response data from the interviews in conjunction with the response data from the surveys, we identify the key concerns that inhibit social scientists from (1) applying social media for professional purposes and (2) making use of the wide array of metrics available.
Our findings show that aspects of time consumption, privacy, dealing with information overload, and prevalent styles of communication are predominant concerns inhibiting Social Science researchers from using social media platforms for their work. Regarding indicators for research impact we identify a widespread lack of knowledge about existing metrics, their methodologies and meanings as a major hindrance for their uptake through social scientists. The results have implications for future developments of scholarly online tools and show that researchers could benefit considerably from additional formal training regarding the correct application and interpretation of metrics.},

However, there is some doubt as to whether these evaluation instruments accurately measure the quality of course content, teaching and knowledge transfer. We investigated whether the provision of chocolate cookies as a content-unrelated intervention influences SET results. Methods We performed a randomised controlled trial in the setting of a curricular emergency medicine course. Participants were 118 third-year medical students. Participants were randomly allocated into 20 groups, 10 of which had free access to 500 g of chocolate cookies during an emergency medicine course session (cookie group) and 10 of which did not (control group). All groups were taught by the same teachers. Educational content and course material were the same for both groups. After the course, all students were asked to complete a 38-question evaluation form. Results A total of 112 students completed the evaluation form. The cookie group evaluated teachers significantly better than the control group (113.4 ± 4.9 versus 109.2 ± 7.3; p = 0.001, effect size 0.68). Course material was considered better (10.1 ± 2.3 versus 8.4 ± 2.8; p = 0.001, effect size 0.66) and summation scores evaluating the course overall were significantly higher (224.5 ± 12.5 versus 217.2 ± 16.1; p = 0.008, effect size 0.51) in the cookie group. Conclusions The provision of chocolate cookies had a significant effect on course evaluation. These findings question the validity of SETs and their use in making widespread decisions within a faculty.},

abstract = {Memory reactivation is a process whereby cueing or recalling a long-term memory makes it enter a new active and labile state. Substantial evidence suggests that during this state the memory can be updated (e.g., adding information) and can become more vulnerable to disruption (e.g., brain insult). Memory reactivations can also prevent memory decay or forgetting. However, it is unclear whether cueing recall of a feature or component of the memory can benefit retention similarly to promoting recall of the entire memory. We examined this possibility by having participants view a series of neutral images and then randomly assigning them to one of four reactivation groups: control (no reactivation), distractor (reactivation of experimental procedures), component (image category reactivation), and descriptive (effortful description of the images). The experiment also included three retention intervals: 1 h, 9 days, and 28 days. Importantly, the participants received three reactivations equally spaced within their respective retention interval. At the end of the interval, all the participants were given an in-lab free-recall test in which they were asked to write down each image they remembered with as many details as possible. The data revealed that both the participants in the descriptive reactivation and component reactivation groups remembered significantly more than the participants in the control groups, with the effect being most pronounced in the 28-day retention interval condition. These findings suggest that memory reactivation, even component reactivation of a memory, makes memories more resistant to decay.},

However, the low completion rates in MOOCs suggest that student engagement and progression in the courses are problematic. Following the increasing adoption of gamification in education, it is possible that gamification can also be effectively adopted in MOOCs to enhance students' motivation and increase completion rates. Yet at present, the extent to which gamification has been examined in MOOCs is not known. Considering the myriad gamification elements that can be adopted in MOOCs (e.g., leaderboards and digital badges), this theoretical research study reviews scholarly publications examining gamification of MOOCs. The main purpose is to provide an overview of studies on gamification in MOOCs, types of research studies, theories applied, gamification elements implemented, methods of implementation, the overall impact of gamification in MOOCs, and the challenges faced by researchers and practitioners when implementing gamification in MOOCs. The results of the literature study indicate that research on gamification in MOOCs is in its early stages. While there are only a handful of empirical research studies, results of the experiments generally showed a positive relation between gamification and student motivation and engagement. It is concluded that there is a need for further studies using educational theories to account for the effects of employing gamification in MOOCs.},

An vier Beispielen (Interaktivität, Selbstreguliertes Lernen, Audience-Response-System mit Lernspielen und Pädagogische Agenten) soll in diesem Beitrag die Ambivalenz mediendidaktischer Feldforschung aufgezeigt werden: Es zeigten sich einerseits die üblichen Beschränkungen dieser Art von Forschung (z. B. Bedingungskontrolle, fehlende Randomisierung, Selbstselektion und Konfundierungen), andererseits konnte die differenzielle Wirkung der oben erwähnten Medien offengelegt werden. Dem erhöhten Aufwand an Personal, Material und Zeit steht ein Erkenntnisgewinn bzgl. der Effekte des eigenen Lehrens gegenüber, der zur weiteren Verbesserung genutzt werden kann.},

The winning streak has been used in sport and video games to describe a consecutive number of successful actions and increase players' attention to complete their goal. Similarly, in gamified education system, the winning streak is employed as a game element to boost up motivation of learners. By applying game refinement theory as an assessment method, enjoyment of two user groups in Duolingo is measured to compare. The results indicate that the winning streak can boost up learners' motivation and attention to complete their goals. It also expressed that the winning streak is more significant for advanced learners who are in the high level of milestone than those who are in the low level of milestone.},

However, in such a disintermediated environment misinformation is pervasive and attempts to debunk are often undertaken to contrast this trend. In this work, we examine the effectiveness of debunking on Facebook through a quantitative analysis of 54 million users over a time span of five years (Jan 2010, Dec 2014). In particular, we compare how users usually consuming proven (scientific) and unsubstantiated (conspiracy-like) information on Facebook US interact with specific debunking posts. Our findings confirm the existence of echo chambers where users interact primarily with either conspiracy-like or scientific pages. However, both groups interact similarly with the information within their echo chamber. Then, we measure how users from both echo chambers interacted with 50,220 debunking posts accounting for both users consumption patterns and the sentiment expressed in their comments. Sentiment analysis reveals a dominant negativity in the comments to debunking posts. Furthermore, such posts remain mainly confined to the scientific echo chamber. Only few conspiracy users engage with corrections and their liking and commenting rates on conspiracy posts increases after the interaction.},

So as to reach this goal, the Duolingo platform, one of the most popular apps among L2 learners, was analyzed in terms of its possibilities and limitations for L2 learning as perceived by its users. With that aim, a study was carried out with 80 participants, 45 of whom were L2 learners who answered an online survey about their preferences for L2 learning, 25 MALL users and 10 L2 teachers who were interviewed. Data analysis used a mixed methods design with predominantly qualitative data. Results of the study showed that participants recognize the relevance of MALL for L2 learning and think that the Duolingo may aid L2 learning to a certain extent, but agree that a teacher is necessary to foster interaction and the development of production skills in L2. Based on these results the study concluded that L2 teachers should consider using blended approaches combining MALL in traditional classes.},

Over-featured interfaces are seen as a problem as they can confuse and over-complicate everyday interactions. Researchers also often claim that users do not read product documentation, although they are often exhorted to ‘RTFM’ (read the field manual). We conducted two sets of studies with users which looked at the issues of both manuals and excess features with common domestic and personal products. The quantitative set was a series of questionnaires administered to 170 people over 7 years. The qualitative set consisted of two 6-month longitudinal studies based on diaries and interviews with a total of 15 participants. We found that manuals are not read by the majority of people, and most do not use all the features of the products that they own and use regularly. Men are more likely to do both than women, and younger people are less likely to use manuals than middle-aged and older ones. More educated people are also less likely to read manuals. Over-featuring and being forced to consult manuals also appears to cause negative emotional experiences. Implications of these findings are discussed.},

Here, we present an overview of the types of climate change game currently available, the benefits and trade-offs of their use, and reasons why they hold such promise for education and engagement regarding climate change.},

Language is learned through translation with, according to developers, Duolingo being as effective as any of the leading language learning software. For translating the web, machine translation is not good enough and relying only on professional translators, far too expensive. Duolingo, we are told, offers a third way, with translation as a by-product of its language learning. Translation which will be, if as promised, almost as cheap as if done by machines and almost as good as if by professionals. Launched in June 2012, Duolingo boasts already at the time of writing 300,000 active language learners ready for the task. This article independently assesses the extent to which Duolingo, at its current stage of development, meets those expectations.},

Indeed, the search for gender differences can work against diversity which we define as a cross-gender spectrum of characteristics, interests, abilities, experiences, beliefs and identities. Our ongoing case studies at Carnegie Mellon University (CMU) provide evidence to show that a focus on culture offers the most insightful and effective approach for investigating women’s participation in CS. In this paper, we illustrate this approach and show the significance of cultural factors by describing a new case study which examines the attitudes of CS majors at CMU. Our analysis found that most men and women felt comfortable in the school, believed they could be successful in the CS environment at CMU, and thought they fit in socially and academically. In brief, we did not see any evidence of a strong gender divide in student attitudes towards fitting in or feeling like they could be successful; indeed we found that the Women-CS fit remained strong from prior years. Hence, our research demonstrates that women, alongside their male peers, can fit successfully into a CS environment and help shape that environment and computing culture, for the benefit of everyone, without accommodating presumed gender differences or any compromises to academic integrity.},

abstract = {Ziel der Studie: Wir untersuchen die höheren Bestehensraten männlicher Studierender bei der summativ-integrativen Prüfung (SIP-1) am Ende des ersten Studienjahres des Medizinstudiums an der Medizinischen Universität Wien. Obwohl Schulleistungen (Mathematik, Chemie, Physik, Englisch) in allen unseren Untersuchungen als Erfolgsprädiktor bestätigt wurden und obwohl weibliche Studierende in diesen Fächern signifikant bessere Schulleistungen aufweisen, weisen weibliche Studierende geringere Erfolgsraten auf. Als Erklärung dafür nehmen wir geschlechtsspezifisch unterschiedliches und erfolgsrelevantes „strategisches Lernen“ an.

Methode: In einer prospektiven Studie an 726 Studierenden der Medizinischen Universität Wien wurde „strategisches Lernverhalten“ mit einem Fragebogen (45 Items) erhoben. Eine Faktorenanalyse ergibt 11 Faktoren, welche mit den Prüfungsergebnissen (bestanden/nicht bestanden) und dem Geschlecht in Beziehung gesetzt werden.

Ergebnisse: Acht der 11 Faktoren erwiesen sich als geschlechtsabhängig oder mit dem Prüfungserfolg verbunden, vier von diesen als sowohl geschlechtsabhängig als auch erfolgsrelevant („Erfolgssicherheit“, „laufend und viel mitlernen“, „hohe Lernkapazität“, „ängstlich/fleißig/strategielos“). Männliche Studierende zeigen eine deutlich strategischere Ausrichtung ihres Lernverhaltens. Interessant erscheint darüber hinaus, dass ein auf Verstehen ausgerichtetes Lernen für den Prüfungserfolg nicht relevant ist.

Schlussfolgerungen: Das Lernverhalten von Mädchen, das grosso modo in der Schule zu besseren Leistungen führt, erweist sich in der Situation der SIP-1 als nicht zielführend. Es wird zu überlegen sein, inwieweit auf Gender-bezogene Differenzen in der Planung von Curriculum und Prüfungswesen Bedacht genommen werden kann.},
