The number line estimation task is an often-used measure of numerical magnitude understanding. The task also correlates substantially with broader measures of mathematical achievement. This raises the question of whether the task would be a useful component of mathematical achievement tests and instruments to diagnose dyscalculia or mathematical giftedness and whether a stand-alone version of the task can serve as a short screener for mathematical achievement. Previous studies on the relation between number line estimation accuracy and broader mathematical achievement were limited in that they used relatively small nonrepresentative samples and usually did not account for potentially confounding variables. To close this research gap, we report findings from a population-level study with nearly all Luxembourgish ninth-graders (N = 6484). We used multilevel regressions to test how a standardized mathematical achievement test relates to the accuracy in number line estimation on bounded number lines with whole numbers and fractions. We also investigated how these relations were moderated by classroom characteristics, person characteristics, and trial characteristics. Mathematical achievement and number line estimation accuracy were associated even after controlling for potentially confounding variables. Subpopulations of students showed meaningful differences in estimation accuracy, which can serve as benchmarks in future studies. Compared with the number line estimation task with whole numbers, the number line estimation task with fractions was more strongly related to mathematical achievement in students across the entire mathematical achievement spectrum. These results show that the number line estimation task is a valid and useful tool for diagnosing and monitoring mathematical achievement. [less ▲]

Basic mathematics skills build on nonverbal number sense But these innate non-verbal skills are insufficient to develop symbolic exact number concepts and to learn arithmetic. Language development allows the acquisition of number words and math vocabulary, crucial for developing basic exact number concepts and arithmetic skills. This presentations highlights five key aspects on how language influences mathematical development. First, language is a building block for basic math skills. Second, number naming systems affect number transcoding. Third, multilingual students calculate better in the language in which they have learned numbers. Forth, children's home language influences their mathematics achievement. And finally, the mastery of the language of instruction has a strong impact on mathematics achievement. The implication of these key aspects are discussed with regard to education and instruction in schools. [less ▲]

For decades, researchers have been raising awareness of the issue of educational inequalities in the multilingual Luxemburgish school system. Especially children from families with a migration background or a lower socio-economic status show large deficits in their language and mathematics competences in comparison to their peers. The same applies to children who do not speak Luxemburgish or German as their first language (Hornung et al., 2021; Sonnleitner et al., 2021). One way to reduce such educational inequalities might be an early and extensive participation in early childhood education and care (ECEC). Indeed, participation in ECEC was found to be positively connected to language and cognitive development in other countries, especially for children from disadvantaged families (Bennett, 2012). However, these children attend ECEC less often (Vandenbroeck & Lazzari, 2014). There are indications that lower parental costs might go hand in hand with a greater attendance of ECEC in general (for a Luxembourgish study, see Bousselin, 2019) and in particular by disadvantaged families (Busse & Gathmann, 2020). The aim of this study is to spotlight the attendance of ECEC in Luxembourg during the implementation of the ECEC reform after 2017 which increased free ECEC hours for all families from 3 to 20 hours a week. We draw on a large dataset of about 35.000 children from the Épreuves Standardisées (ÉpStan, the Luxemburg school monitoring programme) from 2015 to 2021 and investigate which children attend any kind of regulated ECEC service (public, private or family daycare) in which intensity, taking socio-economic and cultural family factors into account. The findings might help to understand in which contexts ECEC attendance should be further encouraged. Implications for future policy decisions are discussed with the goal of further promoting equal educational opportunities for all children. [less ▲]

Providing timely and adequate support to children experiencing difficulties in reading and writing is key to minimize the impact on children’s academic achievements, social and emotional well-being, particularly for children with specific learning disorders. However, the diagnostic process is especially challenging in Luxembourg’s multilingual educational system with changing instruction languages (Luxembourgish, German, French) and multilingual population. The chosen language of the diagnostic tool is usually identical to the main language of instruction at school, which at time of diagnosis (typically grade 3) is German. This may especially affect the diagnosis of children who do not speak German or Luxembourgish at home as data from the Luxembourgish national school monitoring program reveals significant differences in German reading comprehension in grade 3 depending on the language spoken at home (Hoffmann et al., 2018; Martini et al., 2021). Furthermore, the diagnostic tools currently employed in Luxembourg are developed in countries with primarily one language of instruction, challenging the validity of the diagnostic process in a multilingual population (Ugen et al., 2021). The aim of the current project is to develop a diagnostic tool adapted to the Luxembourgish educational curriculum, that takes children’s potential proficiency differences in the test language into account in the instructions, tasks and resulting norms. This way, over-diagnosis of reading and writing disorders in children who do not speak the main language(s) of instruction at home and underdiagnosis of children who do, can be avoided. The developed test battery assesses children’s performance in key domains relevant for reading and writing comprising phonological skills, (non)word and text reading (fluency and accuracy), reading comprehension, writing, and vocabulary. We will present the pre-test results of 9 sub-tests completed by 214 children, providing the first insights into the test development and validation process.   References Hoffmann, D., Hornung, C., Gamo, S., Esch, P., Keller, U., & Fischbach, A.

Today’s educational field has a tremendous hunger for valid and psychometrically sound items to reliably track and model students’ learning processes. Educational large-scale assessments, formative classroom assessment, and lately, digital learning platforms require a constant stream of high-quality, and unbiased items. However, traditional development of test items ties up a significant amount of time from subject matter experts, pedagogues and psychometricians and might not be suited anymore to nowadays demands. Salvation is sought in automatic item generation (AIG) which provides the possibility of generating multiple items within a short period of time based on the development of cognitively sound item templates by using algorithms (Gierl & Haladyna, 2013; Gierl et al., 2015). The present study psychometrically analyses 35 cognitive item models that were developed by a team of national subject matter experts and psychometricians and then used for algorithmically producing items for the mathematical domain of numbers & shapes for Grades 1, 3, 5, and 7 of the Luxembourgish school system. Each item model was administered in 6 experimentally varied versions to investigate the impact of a) the context the mathematical problem was presented in, and b) problem characteristics which cognitive psychology identified to influence the problem solving process. Based on samples from Grade 1 (n = 5963), Grade 3 (n = 5527), Grade 5 (n = 5291), and Grade 7 (n = 3018) collected within the annual Épreuves standardisées, this design allows for evaluating whether psychometric characteristics of produced items per model are a) stable, b) can be predicted by problem characteristics, and c) are unbiased towards subgroups of students (known to be disadvantaged in the Luxembourgish school system). After item calibration using the 1-PL model, each cognitive model was analyzed in-depth by descriptive comparisons of resulting IRT parameters, and the estimation of manipulated problem characteristics’ impact on item difficulty by using the linear logistic test model (LLTM, Fischer, 1972). Results are truly promising and show negligible effects of different problem contexts on item difficulty and reasonably stable effects of altered problem characteristics. Thus, the majority of developed cognitive models could be used to generate a huge number of items (> 10.000.000) for the domain of numbers & operations with known psychometric properties without the need for expensive field-trials. We end with discussing lessons learned from item difficulty prediction per model and highlighting differences between the Grades. References: Fischer, G. H. (1973).

Antônio ist ein Junge aus Luxemburg im schulpflichtigen Alter. Er wird demnächst Lesen und Schreiben lernen. Antônios Eltern sind Portugiesen, und zu Hause sprechen sie nur ihre Muttersprache. In Cycle 1 (Vorschule) hat Antônio Luxemburgisch sprechen gelernt. Seit er in der Vorschule mit der Sprache in Berührung gekommen ist, hat er sich einen großen Wortschatz in Luxemburgisch angeeignet. Wortschatzkenntnisse gehören zu den wichtigsten Voraussetzungen für das Lesen (Lervåg & Aukrust, 2010). Kinder, die das Lesenlernen mit umfangreicheren Wortschatzkenntnissen beginnen, haben bessere Chancen auf Lernerfolge beim Lesen. Für Kinder in Luxemburg ist es eine große Herausforderung, dass der Schriftspracherwerb in Deutsch erfolgt, das für die meisten von ihnen eine Fremdsprache ist, und nicht in Luxemburgisch, also der Sprache, die sie zuvor in Cycle 1 gelernt haben.
