This study explored the transactional association between anxiety symptoms and risk-avoidance in Dutch elementary schoolchildren (N = 1200; 50% girls) across ages 8–12. Anxiety symptoms were obtained using self-, peer-, and teacher-reports. Risk-avoidance was measured using the Balloon Analogue Risk Task—Youth Version. Random-intercept cross-lagged panel models showed that, across informants, increases in anxiety symptoms predicted decreases in risk-taking. Apart from minor exceptions, this effect was similar across sexes. For peer-reports, the reverse path from decreases in risk-taking to increased anxiety was also found. Overall, this study gives insight into the developmental link between symptoms of anxiety and risk-avoidance which is important for early signaling and prevention as well as for our understanding of the consequences of childhood anxiety symptoms. 相似文献

This study investigated the strategy characteristics and development of children with mathematical disabilities (MD) in the domain of simple addition and subtraction, in terms of Lemaire and Siegler's model of strategic change, using the choice/no-choice method and the combined chronological-age (CA)/ability-level (AL)-match design. Four groups of children, matched on either CA or mathematical AL, solved a series of 36 problems with the bridge over 10 in four conditions. In the choice condition, children could choose between retrieval, decomposition to 10, and counting on to solve each problem. In the retrieval, decomposition, and counting conditions, they had to answer the same 36 problems using retrieval, decomposition to 10, and counting on, respectively. The results revealed clear differences in the frequency, efficiency, and adaptiveness with which the CA-matched children applied the available strategies. In contrast, we observed no differences in strategy frequency, efficiency, and adaptiveness between the AL-matched children. These results support the hypothesis that the strategy development of children with MD is marked by a delay rather than a specific deficit. Moreover, this study further documents the value of the methodology used to study children's strategy use and development in the domain of simple arithmetic. 相似文献

Several studies have reported significant relationships between children’s season of birth and measures of their academic success (i.e., the ‘season of birth effect’). Whereas most of these studies were cross‐sectional, the current study uses growth curve modelling to analyse longitudinal data on 3,187 children in Flemish primary education. The results indicate season of birth effects on both grade retention and mathematics achievement during the first two years of primary school. Because the Flemish cut‐off date is 31 December, children born in the fourth quarter (October‐November‐December) invariably are among the youngest in their grade age group. Almost 20% of these children were found to have been retained or referred to special education by the end of Grade 2, whereas for children born in the first quarter (January‐February‐March), this was only 6.34%. First quarter‐born children also showed moderately higher mathematics achievement at the start of first grade. During the next two school years, this achievement gap between children born in the first and the fourth quarter narrowed significantly. Finally, differentiated instruction was not found to be related to the decrease of the season of birth effect. 相似文献

We explored the genetic background of individual differences in dynamic measures of verbal learning ability in children, using a Dutch version of the Auditory Verbal Learning Test (AVLT). Nine-year-old twin pairs (N = 112 pairs) were recruited from the Netherlands Twin Register. When possible, an older sibling between 10 and 14 years old participated as well (N = 99). To assess verbal learning, non-linear curves were fitted for each child individually. Two parameters were estimated: Learning Speed (LS) and Forgetting Speed (FS). Larger twin correlations in monozygotic (MZ) than in dizygotic (DZ) and sibling pairs for LS and FS indicated the importance of genetic factors in explaining variation in these traits. The heritability estimate (percentage of variance explained by genetic factors) for LS was 43% for both twins and siblings. For FS heritability was estimated at 20% in twins and was slightly higher (30%) in their older siblings. 相似文献

This study aimed at analysing traditionally taught children’s acquisition and use of shortcut strategies in the number domain
20–100. One-hundred-ninety-five second, third, and fourth graders of different mathematical achievement levels participated
in the study. They were administered two tasks, both consisting of a series of two-digit additions and subtractions that maximally
elicit the use of the compensation and indirect addition strategy (, so the answer is 2 + 1 or 3). In the first task, children were instructed to solve all items as accurately and as fast as
possible with their preferred strategy. The second task was to generate at least two different strategies for each item. Results
demonstrated that children of all grades and all achievement levels hardly applied the compensation and indirect addition
strategy in the first task. Children’s strategy reports in the second task revealed that younger and lower achieving children
did not apply these strategies because they did not (yet) discover these strategies. By contrast, older and higher achieving
children appeared to have acquired these strategies by themselves. Results are interpreted in relation to cognitive psychological
and socio-cultural perspectives on children’s mathematics learning.

Clear Self,Better Relationships: Adolescents’ Self‐Concept Clarity and Relationship Quality With Parents and Peers Across 5 Years

This study examined reciprocal associations between adolescents’ self‐concept clarity (SCC) and their relationship quality with parents and best friends in a five‐wave longitudinal study from age 13 to 18 years. In all, 497 adolescents (57% boys) reported on their SCC and all informants (i.e., adolescents, both parents, and adolescents’ best friends) reported on support and negative interaction. Within‐person cross‐lagged analyses provided systematic evidence for both parent effects and child effects, with the direction of effects being strongly dependent on the relational context. For example, higher maternal support predicted higher adolescent SCC, supporting a parent effects perspective, whereas higher SCC predicted lower paternal negative interaction, supporting a child effects perspective. Peer effects on adolescent SCC were not consistently found across adolescent and best friend reports. 相似文献

Many students experience difficulties in solving applied physics problems. Most programs that want students to improve problem-solving
skills are concerned with the development of content knowledge. Physhint is an example of a student-controlled computer program
that supports students in developing their strategic knowledge in combination with support at the level of content knowledge.
The program allows students to ask for hints related to the episodes involved in solving a problem. The main question to be
answered in this article is whether the program succeeds in improving strategic knowledge by allowing for more effective practice
time for the student (practice effect) and/or by focusing on the systematic use of the available help (systematic hint-use
effect). Analysis of qualitative data from an experimental study conducted previously show that both the expected effectiveness
of practice and the systematic use of episode-related hints account for the enhanced problem-solving skills of students. 相似文献
