T1 - Relation between mathematical performance, math anxiety, and affective priming in children with and without developmental dyscalculia T2 - Postprints der Universität Potsdam : Humanwissenschaftliche Reihe N2 - Many children show negative emotions related to mathematics and some even develop mathematics anxiety. The present study focused on the relation between negative emotions and arithmetical performance in children with and without developmental dyscalculia (DD) using an affective priming task. Previous findings suggested that arithmetic performance is influenced if an affective prime precedes the presentation of an arithmetic problem. In children with DD specifically, responses to arithmetic operations are supposed to be facilitated by both negative and mathematics-related primes (= negative math priming effect). We investigated mathematical performance, math anxiety, and the domain-general abilities of 172 primary school children (76 with DD and 96 controls). All participants also underwent an affective priming task which consisted of the decision whether a simple arithmetic operation (addition or subtraction) that was preceded by a prime (positive/negative/neutral or mathematics-related) was true or false. Our findings did not reveal a negative math priming effect in children with DD. Furthermore, when considering accuracy levels, gender, or math anxiety, the negative math priming effect could not be replicated. However, children with DD showed more math anxiety when explicitly assessed by a specific math anxiety interview and showed lower mathematical performance compared to controls. Moreover, math anxiety was equally present in boys and girls, even in the earliest stages of schooling, and interfered negatively with performance. In conclusion, mathematics is often associated with negative emotions that can be manifested in specific math anxiety, particularly in children with DD. Importantly, present findings suggest that in the assessed age group, it is more reliable to judge math anxiety and investigate its effects on mathematical performance explicitly by adequate questionnaires than by an affective math priming task.

Rechenschwächen. Neben der Persistenz wurden Auswirkungen von Rechenproblemen auf künftige Rechenleistungen sowie den Schulerfolg geprüft. Methodik: Für 2909 Schüler der 2. bis 5. Klasse liegen die Resultate standardisierter Rechen- und Intelligenztests vor. Ein Teil dieser Kinder ist nach 37 und 68 Mona-ten erneut untersucht worden. Ergebnisse: Die Prävalenz von Rechenstörungen betrug 1.4 %, Rechenschwächen traten bei 11.2 % auf. Rechen-probleme zeigten eine mittlere bis hohe Persistenz. Schüler mit Rechenschwäche blieben im Rechnen gut eine Standardabweichung hinter durchschnittlich und ca. eine halbe Standardabweichung hinter unterdurchschnittlich intelligenten Kontrollkindern zurück. Der allgemeine Schulerfolg rechenschwacher Probanden (definiert über Mathematiknote, Deutschnote und Schultyp) ähnelte dem der unterdurchschnittlich intelligenten Kontrollgruppe und blieb hinter dem Schulerfolg durchschnittlich intelligenter Kontrollkinder zurück. Eingangs ältere Probanden mit Rechenproblemen (4. bis 5. Klasse) wiesen eine schlechtere Prognose auf als Kinder, die zu Beginn die 2. oder 3. Klasse besuchten. Schluss-folgerungen: Rechenprobleme stellen ein ernsthaftes Entwicklungsrisiko dar. Längsschnittuntersuchungen, die Kinder mit streng definierter Rechenstörung bis ins Erwachsenenalter begleiten und Prädiktoren für unterschiedlich erfolgreiche Verläufe ermitteln, sind dringend notwendig. N2 - Objective: The present study examines the 5 years course of mathematics learning disabilities (MLD) and poor mathematics achieve-ment in children from primary to secondary schools. The study investigates the persistence and the impact of mathematical difficulties on the later mathematics performance and school-related success. Method: First, 2909 second to fifth graders were examined with standardized tests in mathematical skills and intelligence. A part of these children was re-examined after 37 and after 68 months. Results: A prevalence of 1.4 % for MLD and 11.2 % for poor mathematics achievement was determined. Mathematical difficulties showed medium to high persistence. Later performance of children with poor mathematics achievement was one standard deviation below a control group without mathematical difficul-ties with average intelligence and 0.5 standard deviations below a group of children with intellectual deficits. School-related success was a composite score of the mathematics grade, the language grade and school type. Children with poor mathematics achievement showed similar school-related success to children with intellectual deficits. Furthermore, they scored significant lower than children without mathematical difficulties and average intelligence. Older children with mathematical difficulties (4th to 5th grade) showed a poorer prognosis than children attending grade 2 or 3. Conclusion: Poor mathematics achievement is a considerable developmental risk. Large longitudinal studies into adult-hood with strict MLD definition are needed to evaluate predictors of successful developmental courses.

Methodik: 1897 Kindergartenkinder nahmen an dieser Studie teil. Ein Teil dieser Kinder wurde 9 Monate später und erneut in der ersten Klasse untersucht. Ergebnisse: Während des Kindergartenjahres verbesserten sich die Kinder in allen untersuchten Leistungen. Reziproke Zusammenhänge zwischen den drei erhobenen Vorläuferfähigkeiten konnten nachgewiesen werden. Das ZMW erwies sich als guter Prädiktor für die AG- und Intelligenzleistung. Bei der Überprüfung der Vorhersage des Rechnens erwies sich das ZMW als bester Prädiktor der späteren Rechenleistung. Erwartungsgemäß zeigten die zu t1 erfassten allgemein-kognitiven Leistungen indirekte Effekte über das ZMW auf die Rechenleistung. Die Intelligenz und das AG zu t2 konnten direkt zur Vorhersage des Rechnens in der ersten Klasse beitragen. Schlussfolgerungen: Die Ergebnisse verdeutlichen, dass das AG und die Intelligenz zwar an dem Aufbau des ZMW beteiligt sind, aber vor allem selbst durch dieses vorhergesagt werden. Die Daten sprechen dafür das Potenzial des ZMWs in Trainingsprogrammen zu nutzen, durch dessen Förderung auch intellektuelle und Gedächtnisleistungen zunehmen können, die allesamt die schulische Rechenleistung positiv beeinflussen. N2 - Objective: The present study examines the development and reciprocal relation between specific (basic quantity-number competen-cies [QNC]) and general mathematical precursor skills (working memory [WM] and intelligence), and their predictive value for mathematics achievement in the first grade. Methods: 1897 children in kindergarten participated in the present study. These children were retested 9 month later and during the first year of primary school. Cross-lagged panel analysis was used to investigate the longitudinal reciprocal relations be-tween the specific and general mathematical precursor skills in kindergarten. Results: During the last year of kindergarten children showed improvements in all applied measures. Reciprocal relations between the three mathematical precursor skills were found. Basic QNC proved to be a good predictor of WM and intelligence. Results also emphasized basic QNC as the best predictor of mathematics achievement in first grade. As hypothesized, general mathematical precursors at t1 showed indirect effects via QNC on mathematics school achievement. Intelligence and WM at t2 contributed directly to mathematics school achievement. Conclusions: Results reveal that WM and intelligence predict growth in QNC, and furthermore are predicted by QNC themselves. The data emphasize the potential of QNC in training programs, as they might improve intel-lectual and WM performance, which have a positive impact on mathematics school achievement.

Klasse T2 - Postprints der Universität Potsdam : Humanwissenschaftliche Reihe N2 - Fragestellung: Ziel der Studie war die Überprüfung der Wirksamkeit einer vorschulischen Förderung der phonologischen Bewusstheit und der Buchstaben-Laut-Verknüpfung bei Kindern mit einem Risiko für die Entwicklung einer Lese-Rechtschreibstörung (LRS) unter Bedingungen, die sich am Alltag der Kindertagesstätten orientierten und somit auch bei einem breiten Einsatz des Programms eine relativ ökonomische Variante darstellen. Methodik: Die Risikokinder der Trainingsgruppe (n = 20) wurden über 11 Wochen mit den Programmen Hören, Lauschen, Lernen 1 und 2 (Küspert & Schneider, 2008; Plume & Schneider, 2004) von Erzieherinnen gefördert. Sie wurden einer nicht-geförderten Risiko-Kontrollgruppe (n = 43) hinsichtlich ihrer Lese- und Rechtschreibleistungen sowie der Häufigkeit von LRS von der 1. bis zur 3. Klasse gegenübergestellt. Dabei wurden neben den Daten regulär eingeschulter Kinder auch jene in die Analyse inkludiert, die vom Schulbesuch zurückgestellt wurden. Ergebnisse: Im 1. und 2. Grundschuljahr zeigten die trainierten Risikokinder im Lesen und Rechtschreiben einen mindestens tendenziellen Leistungsvorsprung gegenüber nicht-geförderten Risikokindern. Trainingseffekte zeigten sich ebenfalls in einer Reduktion der Anzahl von Kindern mit LRS bis Klasse 2, tendenziell auch in Klasse 3. Schlussfolgerung: Insgesamt sprechen die Befunde für die Wirksamkeit des Trainings in der primären Prävention von Lese-Rechtschreibschwierigkeiten bei Risikokindern unter alltagsnahen Bedingungen. N2 - Objective: The present study evaluates the long-term effects of a preschool training stimulating phonological awareness and letter-sound correspondence in children at risk for dyslexia under conditions tending more to the kindergarten routine than in the context of an intervention study with controlled conditions. Method: The children at risk for dyslexia of the experimental group (n = 20) were trained with Hören, Lauschen, Lernen 1 und 2 (Küspert & Schneider, 2008; Plume & Schneider, 2004) by their kindergarten teachers. They were compared with an untrained control group of children at risk (n = 43) with regard to their reading and spelling achievement and the percentage of dyslexia in 1st, 2nd and 3rd grades. For statistical analyses data of children with a regular and a postponed enrolment at primary school were used. Results: The preschool intervention indicated long-term effects in the 1st and 2nd grade: The trained children at risk tended to outperform the untrained children at risk in their average reading and spelling competences. Furthermore the percentage of children suffering from dyslexia was significantly lower in the training group compared to the control group. Conclusion: In summary, results indicate long-term efficacy of the preschool training and point to the potential of preventing children at risk to develop severe reading and writing problems.

Es wurden 32 Risikokinder mit einer Kombination aus den Förderprogrammen Mathematik im Vorschulalter und Mengen, zählen, Zahlen im letzten Kindergartenjahr von den Erzieherinnen trainiert und mit 38 untrainierten Risikokindern verglichen. Hinsichtlich der kurzfristigen Wirksamkeit zeigten sich positive Trainingseffekte auf die numerischen Leistungen im letzten Kindergartenjahr. Es ließen sich keine signifikanten mittelfristigen Trainingseffekte auf die Rechenleistungen im zweiten Halbjahr der 1. Klasse finden. Das eingesetzte vorschulische Präventionsprogramm leistete danach einen wichtigen Beitrag zur kurzfristigen Verbesserung der mathematischen Basiskompetenzen. N2 - A slew of studies has shown that training programs teaching numerical competencies have positive short-term effects on mathematical performance. The results for the intermediate effects are not consistent and there are only a few studies on this issue. The aim of this investigation was to evaluate the short-term and intermediate effects of a preschool training program stimulating numerical competencies for children at risk of developing dyscalculia (≤ 10th percentile). During the last kindergarten year, 32 children at risk were trained with a combination of the intervention Mathematik im Vorschulalter and Mengen, zählen, Zahlen by their kindergarten teachers, who were trained and supervised. Contents of the preschool training were: counting, number knowledge up to 10, comprehension of quantity concept, visual differentiation, spatial ability, simple arithmetic operation, handling of symbols, realizing abstract–logical correlations, and identifying cause–effect relations. The training lasted 11 weeks and took place twice a week (session duration = 30 – 40 min). Children who participated in at least 50 % of the sessions were included. The control group consisted of 38 untrained children at risk. For measuring numerical competencies in kindergarten, a subtest of the instrument Basisdiagnostik Umschriebener Entwicklungsstörungen im Vorschulalter – Version III (BUEVA-III) was used, and for measuring mathematical performance the test Deutsche Mathematiktest für erste Klassen (DEMAT 1+) was used. Before the training there were no group differences between the training and control group regarding mathematical performance and overall intelligence. The training showed positive short-term effects for numerical competencies in the last kindergarten year (medium effect size). While trained children could significantly improve their mathematical competencies to an average level (from 34 to 41 t-value points), the performances of the untrained children stayed below average. Unfortunately, there were no significant intermediate effects for mathematical performance in the second half of the first grade. Regarding the diagnosis of dyscalculia as defined by the ICD-10, it was not possible to gather a sufficiently large sample in the first grade fulfilling the criteria to test differences between training and control groups. Methodological limitations of this study were the missing random allocation to treatment conditions, a large drop-out rate, and long testing periods. The preschool training that was used to stimulate numerical competencies contributed significantly toward improving numerical competencies in the short term. Further investigations will determine the long-term effects of the training in the second and third grade. This is particularly important because dyscalculia occurring from the second grade on is a stable phenomenon.

T1 - Efficacy of a Computer-Based Learning Program in Children With Developmental Dyscalculia BT - What Influences Individual Responsiveness? T2 - Postprints der Universität Potsdam : Humanwissenschaftliche Reihe N2 - This study presents the evaluation of a computer-based learning program for children with developmental dyscalculia and focuses on factors affecting individual responsiveness. The adaptive training program Calcularis 2.0 has been developed according to current neuro-cognitive theory of numerical cognition. It aims to automatize number representations, supports the formation and access to the mental number line and trains arithmetic operations as well as arithmetic fact knowledge in expanding number ranges. Sixty-seven children with developmental dyscalculia from second to fifth grade (mean age 8.96 years) were randomly assigned to one of two groups (Calcularis group, waiting control group). Training duration comprised a minimum of 42 training sessions à 20 min within a maximum period of 13 weeks. Compared to the waiting control group, children of the Calcularis group demonstrated a higher benefit in arithmetic operations and number line estimation. These improvements were shown to be stable after a 3-months post training interval. In addition, this study examines which predictors accounted for training improvements. Results indicate that this self-directed training was especially beneficial for children with low math anxiety scores and without an additional reading and/or spelling disorder. In conclusion, Calcularis 2.0 supports children with developmental dyscalculia to improve their arithmetical abilities and their mental number line representation. However, it is relevant to further adapt the setting to the individual circumstances.

Pre-School Children’s Spontaneous Focusing on Numerosity and Their Development of Arithmetical Skills at School T2 - Zweitveröffentlichungen der Universität Potsdam : Humanwissenschaftliche Reihe N2 - Background: Children’s spontaneous focusing on numerosity (SFON) is related to numerical skills. This study aimed to examine (1) the developmental trajectory of SFON and (2) the interrelations between SFON and early numerical skills at pre-school as well as their influence on arithmetical skills at school. Method: Overall, 1868 German pre-school children were repeatedly assessed until second grade. Nonverbal intelligence, visual attention, visuospatial working memory, SFON and numerical skills were assessed at age five (M = 63 months, Time 1) and age six (M = 72 months, Time 2), and arithmetic was assessed at second grade (M = 95 months, Time 3). Results: SFON increased significantly during pre-school. Path analyses revealed interrelations between SFON and several numerical skills, except number knowledge. Magnitude estimation and basic calculation skills (Time 1 and Time 2), and to a small degree number knowledge (Time 2), contributed directly to arithmetic in second grade. The connection between SFON and arithmetic was fully mediated by magnitude estimation and calculation skills at pre-school. Conclusion: Our results indicate that SFON first and foremost influences deeper understanding of numerical concepts at pre-school and—in contrast to previous findings –affects only indirectly children’s arithmetical development at school.
