App permission requests are a control mechanism meant to help users oversee and safeguard access to data and resources on their smartphones. To decide whether to accept or deny such requests and make this consent valid, users need to understand the underlying reasons and judge the relevance of disclosing data in line with their own use of an app. This study investigates people’s certainty about app permission requests via an online survey with 400 representative participants of the UK population. The results demonstrate that users are uncertain about the necessity of granting app permissions for about half of the tested permission requests. This implies substantial privacy risks, which are discussed in the paper, resulting in a call for user-protecting interventions by privacy engineers. [less ▲]

INTRODUCTION Team-teaching, also known as collaborative-teaching, co-teaching and pair-lecturing has been practiced for ages (Buckley 2000). It is generally described as a positive pedagogical practice that can both enhance learning among students and the experience of teaching among instructors (Plank 2011, 2014). While it is acknowledged that team-teaching is not simple and requires great coordination among instructors, it is presented in gleaming terms for both instructors and students alike. More recent work highlights an increased necessity for collaborative-teaching due to the growing complexity in higher education combined with dwindling resources (Minett-Smith and Davis 2020), or as a deliberate cost-saving measure (Liebel et al. 2017). Yet, little quantitative evidence can be found in the literature showing the positive efficacy of this methodology, relative to Student Evaluation Teaching (SET) measures (for exception see: Carpenter et al. 2007). Thus, this study aims to answer: 1) how prevalent is team-teaching; 2) what are the most common team compositions (number of instructors, gender, instructor status and seniority); 3) are there any significant differences in SET scores relative to differences in composition; and 4) what can we learn from the open-text feedback to help us understand, or contextualize, any quantitative differences found between solo- versus team-taught courses? DATA & METHODS To address our research questions and investigate the contours of team teaching in the Faculty of Humanities, Education and Social Sciences (FHSE) at the University of Luxembourg, we use SET data (course feedback), as an indirect measure of quality of education (Marsh 2007). We use descriptive statistics and regression analysis to examine the quantitative feedback for a total of 2908 courses collected over eight semesters (Winter semester 2015-Summer semester 2019). We compliment these results with content analysis of open-text comments that help us understand and contextualize the quantitative findings. PRELIMINARY RESULTS While course feedback data does not directly measure the quality of learning experienced by students (i.e., whether students learn better in team-taught courses vs. solo instructor courses), it does however shed light on the general sentiment experienced and reported by participating students. Preliminary analyses indicate that approximately 30% of courses are team-taught (60% with two-person teams and 40% with teams of 3 and 4+ instructors). Furthermore, we found that, on average, team-taught courses receive significantly lower ratings from students than solo instructor courses. In the remainder of this article, we analyse this basic finding and discuss the implications for team teaching. [less ▲]

Research in human–computer interaction (HCI) has identified meaning as an important, yet poorly understood concept in interaction design contexts. Central to this development is the increasing emphasis on designing products and technologies that promote leisure, personal fulfillment, and well-being. As spaces of profound historical significance and societal value, museums offer a unique perspective on how people construct meaning during their interactions in museum spaces and with collections, which may help to deepen notions of the content of meaningful interaction and support innovative design for cultural heritage contexts. The present work reports on the results of two studies that investigate meaning-making in museums. The first is an experience narrative study (N = 32) that analyzed 175 memorable museum visits, resulting in the establishment of 23 triggers that inform meaningful interaction in museums. A second study (N = 354) validated the comprehensiveness and generalisability of the triggers by asking participants to apply them to their own memorable museum experiences. We conclude with a framework of meaning in museums featuring the 23 triggers and two descriptive categories of temporality and scope. Our findings contribute to meaning research in HCI for museums through an articulation of the content of meaning-making in the cultural sector. [less ▲]

The ever-increasing scale and complexity of cyber attacks and cyber-criminal activities necessitate secure and effective sharing of cyber threat intelligence (CTI) among a diverse set of stakeholders and communities. CTI sharing platforms are becoming indispensable tools for cooperative and collaborative cybersecurity. Nevertheless, despite the growing research in this area, the emphasis is often placed on the technical aspects, incentives, or implications associated with CTI sharing, as opposed to investigating challenges encountered by users of such platforms. To date, user experience (UX) aspects remain largely unexplored. This paper offers a unique contribution towards understanding the constraining and enabling factors of security information sharing within one of the leading platforms. MISP is an open source CTI sharing platform used by more than 6,000 organizations worldwide. As a technically-advanced CTI sharing platform it aims to cater for a diverse set of security information workers with distinct needs and objectives. In this respect, MISP has to pay an equal amount of attention to the UX in order to maximize and optimize the quantity and quality of threat information that is contributed and consumed. Using mixed methods we shed light on the strengths and weaknesses of MISP from an end-users’ perspective and discuss the role UX could play in effective CTI sharing. We conclude with an outline of future work and open challenges worth further exploring in this nascent, yet highly important socio-technical context. [less ▲]

In 2016, UNESCO estimated that 24.4 million primary school teachers and another 44.4 million secondary school teachers were needed to provide every child in the world access to education. Widespread teacher shortages have led researchers to investigate what motivates candidates to become teachers and to remain in the profession (see for example Watt et al., 2012). Luxembourg is no exception, in 2019 for example, the government wanted to hire 320 new teachers at the fundamental school level; however, only 63 graduates from the country’s main teacher training programme at the University of Luxembourg took the required state exam to join the teaching ranks. The country needs 300 to 400 new fundamental schoolteachers per year to keep up with population growth. To help address this need, we draw on 10 years of admissions data (exam performance and noncognitive indicators) collected from candidates seeking entry to the University of Luxembourg’s teacher training programme. Our study investigates the major correlates, similarities and differences, between candidates that never-registered, i.e., candidates that after being admitted never start the programme; drop-outs, i.e., students that start but never finish; and of course, those that persist until completion. While circumstances may differ between these types of candidates, the first two nevertheless took-up the place that someone else who could have finished and possibly become a teacher. In light of the pressing need for more teachers, this study identifies important factors associated with showing up and staying in the programme until the end. Policy implications are described and discussed. [less ▲]

Cross-border migration leads to a diversification of societies, which is reflected in the education system, where classrooms are composed of students with heterogeneous cultural, linguistic, socio-economic characteristics. However, this diversity is only to a limited extent reflected in the teacher population, even though teachers from different backgrounds can bring specific intercultural competencies, have more positive attitudes toward multicultural heterogeneity and act as role models. To facilitate the diversification of the teaching profession, it is imperative that the cohorts of students entering teacher education programs represent the diversity of societies, however studies have shown students with migration background or from families with lower socio-economic status are underrepresented in such programs. This study considered the demographic constellation of applicants for admission into the teacher education program in Luxembourg (2015-2019) and investigated to what extent the admission process (dis)advantages certain groups. Results revealed that although applications come from diverse backgrounds, proficiency in the country´s native languages poses a disadvantage for students with migration background. In addition, applicants coming from more privileged families stand a better chance of being admitted. Results are interpreted within the framework of social mobility and social reproduction. Implications for the admission to the teachers education program are discussed. [less ▲]

Students with immigrant backgrounds are often disadvantaged in public educational systems. In Luxembourg, about 50% of primary and secondary school students have an immigrant background, most notably from Italy, the former Yugoslavia and Portugal. Using data from Luxembourg’s national school monitoring program, we investigate and document for the first time, existing and emerging differences in academic achievement among different immigrant generations of students. Our results indicate that student achievement in Math, German and French is differentially affected by immigrant generational status and language spoken at home. In addition, we find secondary effects of student social background. [less ▲]

Online services pervasively employ manipulative designs (i.e., dark patterns) to influence users to purchase goods and subscriptions, spend more time on-site, or mindlessly accept the harvesting of their personal data. To protect users from the lure of such designs, we asked: are users aware of the presence of dark patterns? If so, are they able to resist them? By surveying 406 individuals, we found that they are generally aware of the influence that manipulative designs can exert on their online behaviour. However, being aware does not equip users with the ability to oppose such influence. We further find that respondents, especially younger ones, often recognise the "darkness" of certain designs, but remain unsure of the actual harm they may suffer. Finally, we discuss a set of interventions (e.g., bright patterns, design frictions, training games, applications to expedite legal enforcement) in the light of our findings. [less ▲]

Research indicates students with immigrant background are disadvantaged in educational systems of the host country (e.g., OECD, 2018). In Luxembourg, roughly half of the school population has an immigrant background (Lenz & Heinz, 2018), and several studies indicate these students are considerably disadvantaged in terms of educational achievement levels (Hadjar et al., 2015, 2018). Lower achievement may be partly due to difficulties related to displacement and settling of 1st generation immigrant students. Second and later generation students may however also experience disadvantages as they speak languages at home that are different from the two main languages of instruction (i.e., German and French), and their parents may be less familiar with the educational system and less able to provide support for their children (Alba & Foner, 2016). This may explain why educational inequalities persist; however little is known about the influence of language proficiency of different generations of immigrant students on their performance in other school subjects. Therefore, our poster focuses on the effect of generation after controlling for the effect of language on math competency. Using data from the Luxembourg School Monitoring Programme (Épreuves Standardisées) for the 2016 cohort of 9th grade students in the two main tracks of secondary school (n=4,339), we conduct regression analysis to investigate to what extent language proficiency in German and French and generational status have an impact on math performance. Data indicates that language proficiency in both German and French explains a significant proportion of variance in math performance. In addition, there is a generation effect, whereby 3rd and later generation immigrant students achieve a higher level of math competency than students of the 1st or 2nd generation. Results will be discussed in terms of social mobility and educational inequality. [less ▲]

In the United States, much has been written about the upward or downward social mobility of the so-called, “New Second Generation”. In Europe, this topic has only recently begun to take shape; mostly in regard to the Netherlands, Germany, France and the UK. In the context of Luxembourg, however, there is very little literature on this topic even though nearly 50% of its population is now of immigrant status. Though small in geography and population, Luxembourg is a founding member of the E.U. and quite literally in the heart of continental Europe. It hosts a diverse set of immigrant groups, continuously attracting economic and some political immigrants, most notably from Italy, the former Yugoslavia and Portugal. Each of these groups arriving at a specific sociohistorical moment: Italians at the height of the steel industry, former Yugoslavians fleeing war, and Portuguese to meet construction and service industry needs. Consequently, Luxembourg is truly a multilingual and multicultural country that makes for a fascinating microcosm to test and explore existing theories of immigrant integration. Its context presents a unique opportunity to study and extrapolate from to anticipate the needs of immigrants elsewhere. Using 2016 data from Luxembourg’s school monitoring programme (ÉpStan), we investigate existing and emerging differences in academic achievement among 1st, 2nd, and later generation immigrant groups in Luxembourg. We analyse math and language proficiencies (German and French) among a cohort of secondary school students (9th grade, N=6286). Preliminary results indicate clear generational differences. These are interpreted in relation to immigrant group characteristics and acculturation in Luxembourg. Implications for the new second generation in the European context will be discussed. [less ▲]

In Luxemburg erreichen viele Jugendliche ein gutes Lesekompetenzniveau nicht nur in einer, sondern gleich in zwei Sprachen. Allerdings wird wiederholt darauf hingewiesen, dass die Lesekompetenzen in Luxemburg stark mit dem familiären Hintergrund der Schülerinnen und Schüler zusammenhängen. Die vorliegende Studie soll jedoch über die Darstellung der Zusammenhänge zwischen den Deutsch- und Französisch-Lesekompetenzen und Einflussfaktoren wie sozio-ökonomischem Hintergrund, Migrationsstatus und Muttersprache hinausgehen. In der Tat stellt sich die Frage, ob es Faktoren gibt, die sich positiv auf das Lesekompetenzniveau der Schülerinnen und Schüler auswirken und auf die sie – anders als bei diesen mittlerweile gut belegten Faktoren – selbst Einfluss nehmen können? Das Leseverhalten Jugendlicher stellt hierfür einen naheliegenden Ansatzpunkt dar. Somit wurden die Schülerinnen und Schüler während der ÉpStan 2016 nicht nur zu ihrem familiären, schulischen und persönlichen Hintergrund befragt, sondern erstmals auch zu ihrem außerschulischen Leseverhalten. Hierbei wurde erfasst, wie häufig sie in ihrer Freizeit Texte unterschiedlicher Art (z. B. Erzählungen, Sachtexte, Zeitungsartikel, Foreneinträge oder Emails) lesen, und in welchen Sprachen sie dies tun. Mittels verschiedener Regressionsanalysen wurde der familiäre Hintergrund der Jugendlichen, ihr Leseverhalten, sowie ihr Lesekompetenzniveau im Deutschen und Französischen zueinander in Bezug gesetzt. Die aus diesen Analysen hervorgehenden Ergebnisse belegen eindrücklich, dass neben dem familiären Hintergrund auch die Lesehäufigkeit und die Sprache, in der die Schülerinnen und Schüler üblicherweise lesen, von Bedeutung für das erreichte Lesekompetenzniveau sind. Darüber hinaus haben insbesondere die Textsorten, mit denen sich die Jugendlichen in ihrer Freizeit auseinandersetzen, entscheidenden Einfluss auf ihre Deutsch- und ihre Französisch-Lesekompetenz. Insbesondere die Häufigkeit, mit der Jugendliche angeben, narrative Texte (wie Geschichten, Romane oder Erzählungen) zu lesen, steht deutlich in positivem Zusammenhang mit ihrer Lesekompetenz in beiden Sprachen. Der Vortrag schließt mit einer Diskussion bezüglich der außerordentlich hohen Attraktivität von digitalen Textsorten bei Kindern und Jugendlichen, und den Möglichkeiten, diese Vielfalt an primär kommunikativ bzw. interaktiv ausgerichteten Lesematerialien als lebensnahe, pädagogische „Sprungbretter“ zu nutzen, mit deren Hilfe zukünftige Leserinnen und Leser an zunehmend komplexere Texte herangeführt werden könnten.

En matière d’éducation en général, et plus précisément dans le contexte de l’acquisition de compétences et de connaissances scolaires, on ne cesse de souligner que dans beaucoup de pays il existe des écarts importants entre des élèves en fonction de leur arrière-fond socio-économique, de leur langue maternelle, ou de leur statut de migration. Souvent, cependant, il importe de clarifier quelles pourraient être des caractéristiques qui interagissent avec les variables pré-mentionnées. Cela aiderait à saisir le pourquoi des ces différences et à élucider quelles mesures de soutien pourraient être adoptées. En supposant que la fréquence de lecture puisse avoir un impact important sur le niveau de lecture, nous nous intéressons, dans la présente étude, aux différences en matière de lecture et ce en fonction des différentes caractéristiques socio-culturelles et des habitudes de lecture des élèves. À cet effet, nous aurons recours aux données issues des Épreuves Standardisées de l’année 2016/2017. Tous les élèves du grade 9 de l’enseignement secondaire du Luxembourg y ont participé à des tests de lecture de textes en français et en allemand. En outre, ces mêmes élèves ont été questionnés sur leur arrière-fond socio-culturel, ainsi que sur leurs habitudes de lecture. Plus précisément, il leur était demandé d’indiquer à quelle fréquence ils lisaient différents types de textes en dehors de l’école. Les résultats montrent que les textes en format numérique sont ceux qui sont le plus attrayants pour les adolescents. Cette préférence générale pour des textes numériques se retrouve parmi tous les groupes socio-culturels sans exception. Des analyses de régression mettent en évidence que ce sont surtout le fait et la fréquence de lire des textes narratifs qui ont un impact sur les compétences de lecture, et ce même si on prend en compte les variables d’arrière-fond socio-culturel des élèves. La discussion des résultats mettra d’un côté l’accent sur l’importance de la lecture ainsi que sur les possibilités de stimuler la motivation de lecture auprès des jeunes, mais aussi sur la popularité croissante de textes en format numérique et les conséquences correspondantes.
