Classroom     

P. Jayanth Vyasanakere  K. Sudeesh 《Resonance》2008,13(8):768-771

In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. We may suggest strategies for dealing with them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences and viewpoints on matters related to teaching and learning science. This project was done as part of the Research Education Advancement Programme held over weekends at the Bangalore Association for Science Education, Jawaharlal Nehru Planetarium, Bangalore.  相似文献   

Genetic and environmental influences on reading and listening comprehension     

Janice M. Keenan  Rebecca S. Betjemann  Sally J. Wadsworth  John C. DeFries  Richard K. Olson 《Journal of Research in Reading》2006,29(1):75-91

We report preliminary behaviour genetic analyses of reading and listening comprehension from The Colorado Learning Disabilities Research Center. Although the twin sample with these new measures is still of limited size, we find substantial, and significant, genetic influences on individual differences in both reading and listening comprehension. In addition, word recognition and listening comprehension each accounted for significant independent genetic influences on reading comprehension. Together, they accounted for all the genetic influence on reading comprehension, indicating a largely genetic basis for the ‘simple model’ of individual differences in reading comprehension proposed by Hoover and Gough (1990) .  相似文献

Comparing Automatic and Manual Measures of Parent–Infant Conversational Turns: A Word of Caution     

Naja Ferjan Ramírez  Daniel S. Hippe  Patricia K. Kuhl 《Child development》2021,92(2):672-681

The Language ENvironment Analysis system (LENA) records children’s language environment and provides an automatic estimate of adult–child conversational turn count (CTC). The present study compares LENA’s CTC estimate to manually coded CTC on a sample of 70 English-speaking infants recorded longitudinally at 6, 10, 14, 18, and 24 months of age. At each age, LENA’s CTC was significantly higher than manually coded CTC (all ps < .001, Cohen’s ds: 0.9–2.05), with the largest discrepancies between the two methods observed at younger ages. The Limits of Agreement Analyses confirm wide disagreements between the two methods, highlighting potential problems with automatic measurement of parent–infant verbal interaction. These findings suggest that future studies should validate LENA’s CTC estimates with manual coding.  相似文献   

Let’s Cross the Next One: Parental Scaffolding of Prospective Control Over Movement     

Elizabeth E. O’Neal  Shiwen Zhou  Yuanyuan Jiang  Joseph K. Kearney  Jodie M. Plumert 《Child development》2021,92(2):e173-e185

This investigation examined parental scaffolding of children’s prospective control over decisions and actions during a joint perception-action task. Parents and their 6-, 8-, 10-, and 12-year-old children (N = 128) repeatedly crossed a virtual roadway together. Guidance and control shifted from the parent to the child with increases in child age. Parents more often chose the gap that was crossed and prospectively communicated the gap choice with younger than older children. Greater use of an anticipatory gap selection strategy by parents predicted more precise timing of entry into the gap by children. This work suggests that social interaction may serve as an important experiential mechanism for the development of prospective control over decisions and actions in the perception–action domain.  相似文献   

Toddlers learn and flexibly apply multiple possibilities     

Mariel K. Goddu  J. Nicholas Sullivan  Caren M. Walker 《Child development》2021,92(6):2244-2251

The ability to consider multiple possibilities forms the basis for a wide variety of human-unique cognitive capacities. When does this skill develop? Previous studies have narrowly focused on children's ability to prepare for incompatible future outcomes. Here, we investigate this capacity in a causal learning context. Adults (N = 109) and 18- to 30-month olds (N = 104) observed evidence that was consistent with two hypotheses, each occupying a different level of abstraction (individual vs. relational causation). Results suggest that adults and toddlers identified multiple candidate causes for an effect, held these possibilities in mind, and flexibly applied the appropriate hypothesis to inform subsequent inferences. These findings challenge previous suggestions that the ability to consider multiple alternatives does not emerge until much later in development.  相似文献   

Self-Regulatory Development in Children from Chinese Immigrant Families: Evidence for Commonality and Specificity     

Stephen H. Chen  Xue Fang Deng  Emily Zhang  Leslie K. Wang  Cindy H. Liu 《Child development》2021,92(6):e1126-e1137

A central theme of acculturative specificity is the heterogeneity of the immigrant experience. This study integrated this application of the Specificity Principle with intergenerational transmission models of self-regulation and identified both common and specific pathways in the self-regulatory development of Chinese American children in immigrant families (N = 169, M_age = 9.2 years). Consistent with intergenerational transmission models, results indicated associations between parents’ and children’s effortful control, with the mediation of these associations via authoritarian parenting. Parental education, family income, and children’s bilingual proficiency were also uniquely associated with children’s executive function and effortful control. Together, findings provide new directions for research with ethnic minority immigrant families, and underscore the utility of within-group approaches in advancing research on ethnic minority children’s development.  相似文献   

Fish Oil Supplementation in Pregnancy and Neurodevelopment in Childhood—A Randomized Clinical Trial

A double-blind randomized controlled trial of n-3 long-chain polyunsaturated fatty acid (n-3 LCPUFA) supplementation or matching placebo during third trimester of pregnancy was conducted within the COPSAC₂₀₁₀ mother-child cohort consisting of 736 women and their children. The objective was to determine if maternal n-3 LCPUFA pregnancy supplementation affects offspring neurodevelopment until 6 years. Neurodevelopment was evaluated in 654 children assessing age of motor milestone achievement, language development, cognitive development, general neurodevelopment, and emotional and behavioral problems. Maternal n-3 LCPUFA supplementation during pregnancy improved early language development and reduced the impact of emotional and behavioral problems. The n-3 LCPUFA supplementation was in boys associated with the earlier achievement of gross motor milestones, improved cognitive development, and a reduced impact of emotional and behavioral problems.  相似文献
