We had been teaching a first-year course on “education in the digital age” as a lecture for a few years. However, we have observed, over the last years, that (1) many students failed to pass the exam and (2) that a lot of them, when in their 4th year, had forgotten most of these theoretical foundations. These considerations have driven us to rethink & redesign our teaching methods and how we assess students learning outcomes. Our pedagogical approach combines various learning & teaching methods that require students to actively and collaboratively construct meaningful knowledge and share it in a community of learners using an online digital portfolio. Overall, we are quite satisfied with our teaching approach but will have to improve our formative assessment practices and will have to set up a digital portfolio solution that is more reliable and leads to greater user satisfaction.

A la suite du Traité de Versailles, la Belgique s’agrandit de quelques 60.000 habitants et de 1.000 km², en annexant les deux Kreise allemands d’Eupen et de Malmedy. Tandis que le premier est largement germanophone, le deuxième compte env. 10.000 franco- ou wallonophones autour de Malmedy. La conférence retrace d’abord les origines de cette annexion, des projets d’expansion territoriale, conçus pendant la guerre, aux négociations du Traité de Versailles. Un accent sera mis sur l’élaboration de l’article 34 de ce traité, qui prévoit une forme de « consultation populaire » unique en son genre et dont l’application a lourdement hypothéqué l’intégration des « Nouveaux Belges » dans leur nouvelle patrie. La deuxième partie de la conférence est consacrée au régime de transition que la Belgique y instaure en 1920. Ce gouvernement provisoire placé sous le Haut Commissaire Herman Baltia est alors en charge de l’intégration des habitants dans l’Etat belge. Comment peut-on « gagner les cœurs et les esprits » d’une population qui, encore en 1918, ne se serait jamais vue devenir belge ? La troisième partie traite de la loi d’intégration du 6 mars 1925 qui met fin au régime de transition et intègre les trois cantons d’Eupen-Malmedy-Saint-Vith dans l’arrondissement de Verviers et la province de Liège. Dans ce contexte, des propositions voient le jour qui seront encore d’actualité lors des débats sur l’autonomie culturelle dans les années 1960. La recherche scientifique a montré depuis longtemps que la politique d’intégration belge menée dans la région pendant l’entre-deux-guerres a été un échec – révélé au plus tard en mai 1940. La conférence jette une nouvelle lumière sur les débuts de celle-ci et sur sa perception par la population et les acteurs politiques. [less ▲]

The modelling of a legal text into a machine-processable form, such as a list of logic formulæ, enables a semi-automatic reasoning about legal compliance but might entail some anticipation of legal interpretation in the modelling. The formulæ need therefore to be validated by legal experts, but it is unlikely that they are familiar with the formalism used. This calls for an interdisciplinary validation methodology to ensure that the model is legally coherent with the text it aims to represent but that could also close the communication gap between formal modellers and legal evaluators. This paper discusses such a methodology, providing an human-readable representation that preserves the formulæ's meaning but that presents them in a way that is usable by non-experts. We exemplify the methodology on a use case where Articles of the GDPR are translated in the Reified I/O logic encoded in LegalRuleML. [less ▲]

Classical higher-order logic, when utilized as a meta-logic in which various other (classical and non-classical) logics can be shallowly embedded, is suitable as a foundation for the development of a universal logical reasoning engine. Such an engine may be employed, as already envisioned by Leibniz, to support the rigorous formalisation and deep logical analysis of rational arguments on the computer. A respective universal logical reasoning framework is described in this article and a range of successful first applications in philosophy, artificial intelligence and mathematics are surveyed.

The internal/external frame of reference model (I/E model; Marsh, 1986) depicts the formation of academic self-concept by assuming an interplay of social and dimensional comparison processes within and across different domains. Associations between achievement and self-concept are expected to be positive within one given domain due to social comparisons (i.e., external frame of reference) and negative across different domains due to dimensional comparisons (i.e., internal frame of reference). The Generalized I/E model (GI/E model; Möller, Müller-Kalthoff, Helm, Nagy, & Marsh, 2015) allows for the inclusion of other outcome variables besides academic self-concept, for example, interest or motivation. The present research aimed at applying the GI/E model to the construct of test anxiety, thereby replicating and significantly extending some first supportive findings on the validity of the GI/E model with test anxiety (Arens, Becker, & Möller, 2017). To this end, we expanded the scope of the GI/E model with test anxiety for the first time to four domains; namely math, physics, German, and English. For this purpose, we drew on a sample of N = 305 9th and 10th graders attending the highest ability school track (i.e., Gymnasium) from six different secondary schools in four German federal states. Analyses were carried out using structural equation modelling in Mplus 8. We used school grades in the respective domains as achievement indicators. Test anxiety was assessed separately for each domain while simultaneously differentiating between two components of test anxiety; namely, worry and emotionality. Our results suggested negative within-domain relations between achievement and test anxiety in all four domains (i.e., higher grades were associated with less test anxiety). The pattern of results for the relations across domains was not as clear. Positive links between achievement and test anxiety across domains (i.e., higher grades in domain A were associated with higher test anxiety in domain B) were weak and could only be established for the association between German achievement and students’ worry in mathematics. These findings partially supported the assumptions made by the GI/E model. As such, we replicated preexisting findings and added novel insights to the GI/E model. Our results were discussed within the framework of self-concept theory and research as well as dimensional comparison theory. [less ▲]

The influence of personality on academic outcomes has been demonstrated consistently in previous research. In particular, conscientiousness and its lower order facets generally show the strongest predictive validity for academic success. MacCann et al. (2009) constructed a 68-item questionnaire for the comprehensive assessment of different conscientiousness facets in secondary education. However, such questionnaires are arguably too long for the use in large-scale educational assessments. Investigating the influence of conscientiousness facets within large-scale educational assessments is, nevertheless, crucial for advancing our knowledge of the differential influence of facets on various academic outcomes. Short and psychometrically sound questionnaires are thus required. Currently, no short and yet comprehensive questionnaire assessing the lower order facets of conscientiousness, that is suitable for large-scale educational assessments exists. Therefore, within the present investigation we develop a short-form instrument based upon the seven-factor version (59 items) of the questionnaire presented by MacCann et al. (2009), by using an exhaustive search algorithm and traditional item selection methods. Our sample consists of a large and representative dataset comprising all 9th grade students in Luxembourg from the Luxembourgish national school monitoring system (N = 6325; see epstan.lu), who answered French and German adaptations of the original 59-item questionnaire. We specified the exhaustive search algorithm to select the best possible combination of four items for each lower order facet, by considering goodness of fit criteria, factor saturation statistics, and measurement invariance between the German and French version. In addition, we used Mokken scale analysis and assessed the congruence of item wordings and theoretical definitions of each lower order facet to ensure content validity. We finally selected four to five items per scale based on our analyses. We found good fit statistics for all lower order facet scales (CFI >.95, RMSEA < 0.05), and acceptable to good factor saturation statistics for all but one of these scales (McDonalds ω > 0.7). On top of that, all scales show either scalar invariance, or partial scalar invariance between the German and French language version. The result of our investigation is a short and psychometrically sound instrument for the assessment of the lower order facets of conscientiousness. It is specifically tailored towards the unique context of the multilingual Luxembourgish educational system, and can be used in the upcoming Épstan cohorts. [less ▲]

Already at the beginning of elementary school, students start to develop self-beliefs and attitudes that reflect their motivation, thoughts, and feelings about a specific school domain. The internal/external frame of reference (I/E) model (Marsh, 1986) encapsulates this phenomenon by explicating the formation of academic self-concept through a combination of social (i.e. comparing one’s achievement in one domain with the achievement of one’s peers in the same domain) and dimensional (i.e. comparing one’s achievement in one domain with one’s achievement in another domain) comparison processes. The recently established generalized internal/external frame of reference (GI/E) model (Möller, Müller-Kalthoff, Helm, Nagy, & Marsh, 2015) builds on the I/E model by extending it to the formation of other subject-specific academic self-beliefs and attitudes, such as interest and test anxiety. Despite the salience of the (G)I/E model in educational research, studies investigating the formation of self-beliefs and attitudes according to this model remains scarce among elementary school children. This study aims to contribute to the current literature by examining the associations between verbal and mathematics achievement, on the one hand, and corresponding domain-specific self-concepts and interests, on the other hand. A population of Luxembourgish elementary school students was assessed twice, two years apart (once in Grade 1 and once in Grade 3) as part of the Luxembourgish school monitoring system (EpStan, cohorts 2014 & 2016; epstan.lu). Using a domain-specific approach, students were assessed on math and verbal achievement as well as German- and math self-concept and interest. This culminated in a sample of N = 3606 elementary school children who participated in both waves. German- and math self-concepts and interests were self-reported whereas standardized achievement tests (see epstan.lu) were used as indicators of math and verbal (Luxembourgish for Grade 1 and German for Grade 3) achievement. Cross-lagged structural equation modelling was performed in Mplus 8 using WLSMV estimation for categorical variables. Overall, the results suggest strong support for the (G)I/E model for Grade 3, while only partial support was found for the (G)I/E model for Grade 1. More specifically, for both Grade 1 and Grade 3, achievement was positively related to self-concept and interest within the same domain. Negative relations between achievement and self-concept and interest across domains were found in Grade 3, but not in Grade 1. The findings are discussed within the context of theory and research on self-concept differentiation processes, dimensional comparison theory, and the multilingual Luxembourgish educational system.

Im Rahmen des luxemburgischen Schulmonitorings werden Schlüsselkompetenzen der Schülerinnen und Schüler der luxemburgischen Regelschulen in regelmäßigen Abständen durch die so genannten Épreuves Standardisées (ÉpStan) gemessen. Diese längsschnittliche Begleitung der Schülerinnen und Schüler birgt die einmalige Chance, neue Erklärungsansätze für ein (alt)bekanntes Problem des luxemburgischen Schulsystems zu finden: die großen Unterschiede der Bildungschancen von Schülerinnen und Schüler je nach Geschlecht, sprachlichem und sozioökonomischem Hintergrund. Der vorliegende Beitrag gibt nun einen ersten Einblick in die längsschnittliche Kompetenzentwicklung in den Bereichen Deutsch-Leseverstehen und Mathematik. Hierfür werden die Testergebnisse der untersuchten Schülerkohorte aus den ÉpStan-Kompetenztests 2010 in der 3.Schulstufe den Leistungen in der 9. Schulstufe im Jahre 2016 gegenübergestellt. Die Darstellung der Entwicklungsverläufe mittels Sankey-Flussdiagrammen, erlaubt ein schnelles und intuitives Verständnis, von welchem Kompetenzniveau die Schülerinnen und Schüler in der 3. Klasse starten und welches sie schließlich in der 9. Klasse erreichen. Der Effekt von nachgewiesenermaßen einflussreichen, demografischen (Hintergrund-) Merkmalen wie Geschlecht, sprachlichem Hintergrund und sozioökonomischem Status wird dabei gesondert analysiert. Beim Blick auf die generellen Entwicklungsverläufe in den Bereichen Deutsch-Leseverstehen und Mathematik fällt vor allem eine sehr hohe Stabilität der Kompetenzeinstufungen auf: Schülerinnen und Schüler der 3. Klasse, deren Leistungen auf dem (erwartungskonformen) Niveau Socle oder Niveau Avancé liegen, verfügen in der Regel auch 6 Jahre später über hohe Deutsch- bzw. Mathematikkompetenzen. Umgekehrt verbleibt die Mehrheit der Schülerinnen und Schüler mit anfänglich schwachen Leistungen auch später auf einem niedrigen Kompetenzniveau. Bezieht man nun die Teilergebnisse zum Sprachhintergrund mit ein, lässt sich ganz klar folgern, dass die Unterrichtssprache hierfür einen entscheidenden Faktor darstellt: Schülerinnen und Schüler, die Luxemburgisch oder Deutsch als Muttersprache angeben, können sowohl in Deutsch-Leseverstehen als auch in Mathematik eher ein hohes Niveau halten bzw. sich im Laufe ihrer Schulkarriere auf ein solches verbessern. Portugiesischsprachige bzw. frankophone Schülerinnen und Schüler, die im Allgemeinen ohnehin auf einem niedrigeren Kompetenzniveau starten, können sich nur teilweise deutlich verbessern, profitieren aber vom Wechsel der Unterrichtssprache im Secondaire. Die Analysen zeigen darüber hinaus, dass typische Geschlechtsunterschiede, die auf einen Vorteil für Mädchen beim Lesen und einen leichten Vorteil für Jungen in Mathematik hindeuten, schon anfangs der 3. Klasse bestehen, und über die folgenden 6 Jahre weitgehend stabil bleiben. Zusammenfassend bestätigen die Ergebnisse die bereits mehrfach aufgezeigten landestypischen Probleme, erlauben aber eine feinere Aufschlüsselung und zeitliche Verortung der Wechselwirkungen zwischen Unterrichtssprache, sprachlichem und sozioökonomischem Schülerhintergrund, und bilden so die Grundlage für effektivere Interventionen.
