The editorial presents the papers of this special issue regarding children at risk of poor educational outcomes. The articles “provide a cross-section of the multifaceted research carried out within this framework. This research demonstrates the various theoretical and methodological approaches that can be used to tackle the question of how to provide support for students at risk.” (DIPF/Orig.

Developmental changes in the association between approximate number representations and addition skills in elementary school children

The approximate number system (ANS) is assumingly related to mathematical learning but evidence supporting this assumption is mixed. The inconsistent findings might be attributed to the fact that different measures have been used to assess the ANS and mathematical skills. Moreover, associations between the performance on a measure of the ANS and mathematical skills may be discontinuous, i.e., stronger for children with lower math scores than for children with higher math scores, and may change with age. The aim of the present study was to examine the development of the ANS and arithmetic skills in elementary school children and to investigate how the relationship between the ANS and arithmetic skills develops. Individual markers of children's ANS (internal Weber fractions and mean reaction times in a non-symbolic numerical comparison task) and addition skills were assessed in their first year of school and 1 year later. Children showed improvements in addition performance and in the internal Weber fractions, whereas mean reaction times in the non-symbolic numerical comparison task did not change significantly. While children's addition performance was associated with the internal Weber fractions in the first year, it was associated with mean reaction times in the non-symbolic numerical comparison task in the second year. These associations were not found to be discontinuous and could not be explained by individual differences in reasoning, processing speed, or inhibitory control. The present study extends previous findings by demonstrating that addition performance is associated with different markers of the ANS in the course of development

Socioscientific decision making in the science classroom: the effect of embedded metacognitive instructions on students' learning outcomes

The purpose of the present study was to examine the effects of cooperative training strategies to enhance students' socioscientific decision making as well as their metacognitive skills in the science classroom. Socioscientific decision making refers to both “describing socioscientific issues” as well as “developing and evaluating solutions” to socioscientific issues. We investigated two cooperative training strategies which differed with respect to embedded metacognitive instructions that were developed on the basis of the IMPROVE method. Participants were 360 senior high school students who studied either in a cooperative learning setting (COOP), a cooperative learning setting with embedded metacognitive questions (COOP+META), or a nontreatment control group. Results indicate that students in the two training conditions outperformed students in the control group on both processes of socioscientific decision making. However, students in the COOP+META condition did not outperform students in the COOP condition. With respect to students' learning outcomes on the regulation facet of metacognition, results indicate that all conditions improved over time. Students in the COOP+META condition exhibited highest mean scores at posttest measures, but again, results were not significant. Implications for integrating metacognitive instructions into science classrooms are discussed

Typizitätsnormen zu sechs taxonomischen und zu acht thematischen Kategorien

Im vorliegenden Abschnitt wird von zwei Studien berichtet, die bereits im Herbst 1984 im Rahmen eines umfangreicheren Projektes zur Bedingungsanalyse verbaler Gedächtnisleistungen bei Viertklässlern begonnen wurden. Im Rahmen dieses Projektes musste die "kategoriale Typizität" von 70 Begriffen aus sechs "taxonomischen" und acht "thematischen Kategorien" beurteilt werden, die als Items in experimentellen Lernuntersuchungen eingesetzt wurden. Daher wurden zunächst Produktionsnormen zu den insgesamt 14 semantischen Kategorien bei Viertklässlern erhoben (Studie 1), die seinerzeit allerdings nur unvollständig (auf die 70 Begriffe beschränkt) ausgewertet wurden. Wegen des weitgehenden Fehlens deutschsprachiger Produktionsnormen von Kindern wurde im Zusammenhang mit der Vorbereitung des vorliegenden Handbuches eine vollständige Auswertung nachgeholt. Im Rahmen einer zweiten Studie wurden zu den gleichen 70 Begriffen der ausgewählten 14 Kategorien Typizitätseinschätzungen erhoben. Neben Grundschulkindern der vierten Klassenstufe nahmen an dieser Studie auch Erwachsene teil, um die Entwicklungsabhängigkeit "kategorialer Typizitäten" für den deutschen Sprachraum zu replizieren.

Spatial representations of numbers and letters in children

Different lines of evidence suggest that children's mental representations of numbers are spatially organized in form of a mental number line. It is, however, still unclear whether a spatial organization is specific for the numerical domain or also applies to other ordinal sequences in children. In the present study, children (n = 129) aged 8–9 years were asked to indicate the midpoint of lines flanked by task-irrelevant digits or letters. We found that the localization of the midpoint was systematically biased toward the larger digit. A similar, but less pronounced, effect was detected for letters with spatial biases toward the letter succeeding in the alphabet. Instead of assuming domain-specific forms of spatial representations, we suggest that ordinal information expressing relations between different items of a sequence might be spatially coded in children, whereby numbers seem to convey this kind of information in the most salient way

Individual differences in children’s early strategy behavior in arithmetic tasks

As demonstrated by the Overlapping Waves Model (Siegler, 1996), children’s strategy use in arithmetic tasks is variable, adaptive, and changes gradually with age and experience. In this study, first grade elementary school children (n = 73), who scored high, middle, or low in a standardized scholastic mathematic achievement test, were confronted with different arithmetic tasks (simple addition, e.g., 3 + 2, simple subtraction, e.g., 7 – 2, and more advanced addition, e.g., 7 + 9) to evoke different calculation strategies. Video analysis and children’s self-report were used to identify individual strategy behavior. In accordance with the Overlapping Waves Model, children in all achievement groups showed variable and multiple strategy usage and adapted their behavior to the tasks of the different categories. We demonstrated that not only low achievers differed from normal achievers but also that high achievers exhibited a unique pattern of strategy behavior in early mathematics

Gender differences in children’s math self-concept in the first years of elementary school

In the course of elementary school children start to develop an academic self-concept reflecting their motivation, thoughts, and feelings about a specific domain. For the domain of mathematics, gender differences can emerge which are characterized by a less pronounced math self-concept for girls. However, studies are rather sparse regarding the early years of elementary school education, hence, the point in time when such gender differences emerge yet remains a matter of debate. In our study, we found that the math self-concept of elementary school children (n = 81) declined from first to second grade. While no differences in math achievement were observed between girls and boys, it became apparent that girls’ math self-concept was already less pronounced than the math self-concept of boys in the first years of elementary school. Our findings emphasize the importance of considering such gender differences even at the beginning of school education

Inhibition in the dynamics of selective attention: an integrative model for negative priming

We introduce a computational model of the negative priming (NP) effect that includes perception, memory, attention, decision making, and action. The model is designed to provide a coherent picture across competing theories of NP. The model is formulated in terms of abstract dynamics for the activations of features, their binding into object entities, their semantic categorization as well as related memories and appropriate reactions. The dynamic variables interact in a connectionist network which is shown to be adaptable to a variety of experimental paradigms. We find that selective attention can be modeled by means of inhibitory processes and by a threshold dynamics. From the necessity of quantifying the experimental paradigms, we conclude that the specificity of the experimental paradigm must be taken into account when predicting the nature of the NP effect

Von Risiken und Ressourcen : LOEWE-Zentrum IDeA erforscht kindliches Lernen

Während Bildungspolitiker heftig über die Abschaffung der Hauptschule streiten und Hamburger Bürger sich per Volksentscheid für den Erhalt des Gymnasiums ab Klasse 5 einsetzen, sind sich die meisten Bildungsforscher einig: Entscheidend ist nicht, wo, sondern wie Kinder unterrichtet und betreut werden. Wie kann es gelingen, pädagogische Interventionen den unterschiedlichen Lernvoraussetzungen so anzupassen, dass möglichst alle Schülerinnen und Schüler optimal gefördert werden? Um das herauszufi nden, bedarf es intensiver Anstrengungen in der Lehr-Lernforschung, wie sie in Frankfurt im Forschungszentrum IDeA unternommen werden

Effects of requested, forced and denied shift schedule change on work ability and health of nurses in Europe: results from the European NEXT-Study

Background: Previous cross-sectional findings from the European Nurses Early Exit Study (NEXT) show that nurses who were dissatisfied with their work schedule tended to consider leaving the nursing profession. Mediating factors in this decision process may be caused by self-perceived poor work ability and/or health. The aim of this paper is to investigate changes in work ability and general health among nurses in relation to requested, forced and denied change of shift schedule. Methods: Longitudinal data from the NEXT Study was used. In total 11,102 nurses from Belgium, Germany, Finland, the Netherlands, Poland, Slovakia, France and Italy completed both the ‘basic questionnaire’ (t1) and the ’12 month follow-up questionnaire’ (t2). To examine the time-effect (repeated measures) and the group-effect of five defined groups of nurses on the Work Ability Index (WAI) and general health (SF36), an adjusted 2-way analysis of covariance (ANCOVA) was performed. Results: The nurses who wanted to, but could not change their shifts during the 12 month follow-up had the lowest initial and follow-up scores for WAI (t1: 37.6, t2: 36.6, p <0.001), lowest general health (t1: 63.9, t2: 59.2, p <0.001) and showed the highest decrease in both outcomes. Shift pattern change in line with the nurses’ wishes was associated with improved work ability and to a lesser comparatively low extent with increased decline in health scores. A forced change of shift against the nurses’ will was significantly associated with a deteriorating work ability and health. Conclusions: The findings would suggest that nurses’ desire to change their shift patterns may be an indicator for perceived low work ability and/or low health. The results also indicate that fulfilling nurses’ wishes with respect to their shift work pattern may improve their personal resources such as work ability and – to somewhat lesser extent – health. Disregarding nurses’ preferences, however, bears the risk for further resource deterioration. The findings imply that shift schedule organization may constitute a valuable preventive tool to promote nurses’ work ability and – to lesser extent – their perceived health, not least in aging nursing work forces
