[more ▼] While numerical skills are fundamental in modern societies, some estimated 5-7% of children suffer from a mathematical learning disorder, called developmental dyscalculia (DD). Nevertheless, universally valid diagnostic instruments are still lacking, as all current DD test batteries are based on language instructions. Consequently, their measurements are tightly linked to the specific language context of test administration and thus their results cannot easily be compared across countries. Here we are showing results of the first pilot study of a research project that aims to develop a test for basic math abilities that does not rely on language instruction and minimizes language use. To this aim, video and animation based instructions were implemented on touchscreen devices. A first version of the tasks has been tested with two samples of first grade children in Luxembourg’s fundamental schools, of which half completed the same tasks with traditional verbal instructions. Our results indicate that performance in the experimental group was similar or better than the control group using verbal instructions. Relationships between linguistic background and the sample’s performance on one hand and qualitative usability aspects of nonverbal task instruction and tablet-pc use with young children will be discussed.

[more ▼] Verbal number skills (i.e. counting and number naming) are milestones in numerical development. The aim of the present study was to clarify the role of different verbal abilities (VA) and visuo-spatial abilities (VSA) in the development of these verbal number skills in kindergarten. We recruited 152 children (mean age: 5.8 years) and administered different measures of VA (e.g. phonological awareness, pseudoword recall) and of VSA (e.g. spatial perception, copying) to assess their contribution to verbal number skills. Firstly, we computed two independent regression models, a “VA only” model explaining 23% of variance, and a “VSA only” model explaining 38% of variance. Adding verbal measures to the “VSA only” model does not lead to a significant increase in R2. Our results show that VSA, rather than VA, contribute to a larger extent to children’s verbal number skills. Intriguingly, the development of verbal number skills builds on VA, but more importantly on VSA. These results are potentially informative for the conception early mathematics interventions.

[more ▼] The present study investigated the predictive role of spatial skills for arithmetic and number line estimation in kindergarten children (N = 125). Spatial skills are known to be related to mathematical development, but due to the construct’s non-unitary nature, different aspects of spatial skills need to be differentiated. In the present study, a spatial orientation task, a spatial visualization task and visuo-motor integration task were administered to assess three different aspects of spatial skills. Furthermore, we assessed counting abilities, knowledge of Arabic numerals, quantitative knowledge, as well as verbal working memory and verbal intelligence in kindergarten. Four months later, the same children performed an arithmetic and a number line estimation task to evaluate how the abilities measured at time 1 predicted early mathematics outcomes. Hierarchical regression analysis revealed that children’s performance in arithmetic was predicted by their performance in the spatial orientation and visuo-motor integration task, as well as their knowledge of the Arabic numerals. Performance in number line estimation was significantly predicted by the children’s spatial orientation performance. Our findings emphasize the role of spatial skills, notably spatial orientation, in mathematical development. The relation between spatial orientation and arithmetic was partially mediated by the number line estimation task. Our results further show that some aspects of spatial skills might be more predictive of mathematical development than others, underlining the importance to differentiate within the construct of spatial skills when it comes to understanding numerical development.

[more ▼] We aimed at investigating the predictive role of spatial skills for arithmetic and number line estimation in kindergarten children (N = 125). Several studies highlighted the relation between spatial skills and mathematics. However, due to their non-unitary nature, different aspects of spatial skills need to be differentiated to clarify the relative importance of different aspects of spatial skills for mathematics. In the present study, at time 1, a spatial perception task, a spatial visualization task and visuo-motor integration task were administered to assess different aspects of spatial skills. Furthermore we assessed domain-specific skills and verbal domain-general skills. Four months later, the same children performed an arithmetic task and a number line estimation task to evaluate how the abilities measured at time 1 predict early mathematics. Hierarchical regression modelling revealed that children’s performance on the spatial perception task was predictive of their performance in both arithmetic and number line estimation, whereas visuo-motor integration and knowledge of the Arabic numerals significantly predicted arithmetic. The predictive relation between spatial perception and arithmetic was partially mediated by the number line estimation task. Our findings emphasize the role of spatial skills, notably spatial perception, in mathematical development. These results reveal the importance to differentiate within the construct of spatial skills when studying their role in numerical development. The development and implementation of pre-school interventions fostering children’s spatial perception and visuo-motor integration might thus be a promising approach for providing children with a sound foundation for later mathematical learning.

[more ▼] Nombreuses études ont pu constater que les aptitudes et les apprentissages précoces influencent les apprentissages académiques ultérieurs. La valeur prédictive de différentes fonctions cognitives à l’âge préscolaire est un sujet toujours vivement discuté. L'apprentissage des mathématiques, de la lecture et de l'écrit sont soutenues par des fonctions cognitives telles que les capacités pré-numériques, le langage, les fonctions visuo-spatiales, les fonctions exécutives dont la mémoire de travail, la vitesse de traitement et la raisonnement logique. Néanmoins, seulement peu de données scientifiques sont actuellement disponibles sur l’apport de ces différentes fonctions cognitives aux apprentissages scolaires dans un contexte multilingue comme celui du Luxembourg. Au Luxembourg environ 35 % des élèves scolarisés à l'école maternelle parlent Luxembourgeois à la maison. La plupart des enfants parlent d'autres langues voire plusieurs langues au sein de leur famille. A l'école maternelle les enfants apprennent le Luxembourgeois pendant 2-3 ans. Ensuite en 1ère année de l'enseignement fondamental primaire public, tous les enfants sont alphabétisés en Allemand. Et ce n'est qu'un an plus tard que le Français s'ajoute aux apprentissages scolaires. L'apprentissage des langues est un projet ambitieux au Luxembourg et les résultats nationaux ont montré que 42 % des élèves en 3e année primaire (CE2) n'ont malheureusement pas obtenu le niveau minimal à atteindre visé par le plan d'étude en 2013 (Hornung, Hoffmann, Lorphelin, Gamo, Ugen, Fischbach, & Martin, 2015). Le but est de développer un instrument qui s'adapte au contexte scolaire multilingue et qui permet de mesurer ces précurseurs cognitifs d’une manière valide. Ce projet vise à mieux comprendre comment différentes capacités cognitives précoces influencent les différents apprentissages scolaires dans un contexte scolaire multilingue chez l’enfant de 4 à 7 ans et les résultats de ce projet pourront servir comme base pour pouvoir développer des outils d’intervention visant à stimuler le développement de ces précurseurs dans un contexte multilingue. La présente batterie de tests inclut plusieurs épreuves brèves individuelles pour évaluer les performances numériques et visuo-spatiales, la capacité d'inhibition verbale et d'inhibition motrice, l'empan de la mémoire de travail verbale et visuo-spatiale, la flexibilité verbale, la vitesse de traitement, la conscience phonologique, la discrimination visuelle et le vocabulaire expressif chez l’enfant de 4 à 7 ans. Ces petites épreuves visent à évaluer ces différents précurseurs cognitifs de l’apprentissage scolaire et elles ont été développées et adaptées spécifiquement pour le contexte préscolaire suite à un pilotage avec la population cible. Dans une première phase, les relations entre ces différentes épreuves seront étudiées pour pouvoir concrétiser notre compréhension sur l’interrelation de ces différents précurseurs cognitifs. Afin de pouvoir évaluer la valeur prédictive de ces différentes fonctions cognitives, une approche longitudinale est visée. Nous avons prévu de mettre en relation les résultats obtenus au préscolaire (Phase I) avec les résultats de ces mêmes enfants obtenus lors des «épreuves standardisées» du monitoring scolaire au Luxembourg, réalisées en première année de l’école primaire (CP en France) (Phase II).

[more ▼] Kapitel 3 befasst sich mit dem Einfluss von Merkmalen des Schülerhintergrundes auf die in den ÉpStan gemessenen Kompetenzen. Diskrepanzen in den erfassten Kompetenzbereichen werden dabei im Hinblick auf folgende vier Hintergrundvariablen untersucht: sozioökonomischer Status, Migrationshintergrund, Sprachhintergrund, sowie das Geschlecht der Schülerinnen und Schüler. Bestehende Unterschiede werden vergleichend für die Jahre 2011, 2012 und 2013 aufgeführt (Zyklus 3.1 und Ve/9e). Das einflussreichste Merkmal ist dabei der sozioökonomische Status, gefolgt von der zuhause gesprochenen Sprache. Der Migrationshintergrund wirkt sich in geringerem Maße bis gar nicht auf die Kompetenzen aus. Der Einfluss des Geschlechtes zeigt sich konform mit einer großen Anzahl von Befunden aus der Forschung: Mädchen erzielen im Durchschnitt bessere Ergebnisse in den Sprachen, während Jungen in Mathematik besser abschneiden.

[more ▼] ÉpStan (Épreuves Standardisées) est une étude annuelle à grande échelle réalisée à Luxembourg depuis 2009. Les ÉpStan ont pour objectif d’évaluer le système éducatif luxembourgeois, en particulier le niveau de compétences atteint en mathématiques des élèves de 3ème et de 9ème année d’étude (âgés en moyenne de 8 ans vs. 14 ans). A partir des résultats mathématiques ÉpStan 2013 du primaire et du secondaire, cette recherche vise d’une part, à examiner si l’écart de performance mathématique entre les sexes constaté par PISA 2012 chez les élèves de 15 ans luxembourgeois est confirmé chez les élèves de 14 ans et chez les élèves plus jeunes (8 ans), (Robinson, & Theule Lubienski, 2011) et d’autre part, à tester si les écarts de performance entre les sexes reflètent des différences de motivation et de confiance en soi et d’anxiété.

[more ▼] Early number competence, grounded in number-specific and domain-general abilities, is supposed to lay the foundation for later math achievement. Few longitudinal studies tested a comprehensive model for early math development. Using structural equation modeling and mediation analyses, we studied the influence of kindergarteners’ basic cognitive abilities (i.e., nonverbal number sense, working memory, fluid intelligence, and receptive vocabulary) and their early number competence (i.e., symbolic number skills) on first grade math achievement (arithmetic, shape and space, and number line estimation) assessed one year later. Latent regression models revealed that nonverbal number sense and working memory are central building blocks for developing early number competence in kindergarten and that early number competence is key for first grade math achievement. Fluid intelligence significantly predicted arithmetic and number line estimation while receptive vocabulary significantly predicted shape and space after controlling for early number competence. In sum we suggest that early math achievement draws on different constellations of number-specific and domain-general mechanisms.

[more ▼] As a direct reaction to alarmingly poor student performance in PISA, like many other European countries Luxembourg started to establish a very ambitious school monitoring program: the Épreuves Standardisées (ÉpStan). One of the core competencies that are measured is, of course, mathematical achievement. Beginning with grade 1 and continued in grade 3 and grade 9, students’ proficiency in several mathematical sub-competencies is assessed. Students have to demonstrate their mathematical problem solving skills in theoretical as well as applied contexts. This design not only allows for tracking individual students’ development of mathematical abilities but also allows for a better understanding of factors that influence this process ̶ a rich and valuable source for the determination of risk factors and the implementation of individual support programs. However, due to the early beginning of this comprehensive program and the heterogeneity of Luxembourg’s students in terms of cultural background and spoken language, several challenges arise, especially for test development. We will present and discuss the theoretical framework of mathematical competencies that is assessed within the ÉpStan and we will show how we are currently using possibilities of computer-based assessment and test design in order to respond to these challenges.

[more ▼] Since 2009, ÉpStan (Épreuves Standardisées) is an annual large-scale study in Luxembourg. It aims to evaluate Luxembourg's school system, in particular students’ achieved competency level in mathematics implemented in 3rd and 9th grade. The present study aims to investigate whether the existing gender gap in mathematics among 15-year-olds revealed by PISA 2012 can be confirmed in ÉpStan 9th grade and if it already exists in younger students’ mathematics performance (ÉpStan 3rd grade) (Robinson, & Theule Lubienski, 2011). Further, we study wether a gender gap in students’ drive, motivation and self-beliefs concerning mathematics performance exists.

[more ▼] Human adults’ numerical representation is spatially oriented; consequently, participants are faster to respond to small/large numerals with their left/right hand, respectively, when doing a binary classification judgment on numbers, known as the SNARC (spatial– numerical association of response codes) effect. Studies on the emergence and development of the SNARC effect remain scarce. The current study introduces an innovative new paradigm based on a simple color judgment of Arabic digits. Using this task, we found a SNARC effect in children as young as 5.5 years. In contrast, when preschool children needed to perform a magnitude judgment task necessitating exact number knowledge, the SNARC effect started to emerge only at 5.8 years. Moreover, the emergence of a magnitude SNARC but not a color SNARC was linked to proficiency with Arabic digits. Our results suggest that access to a spatially oriented approximate magnitude representation from symbolic digits emerges early in ontogenetic development. Exact magnitude judgments, on the other hand, rely on experience with Arabic digits and, thus, necessitate formal or informal schooling to give access to a spatially oriented numerical representation.
