Learning the fundamentals of probability and random variables can be a struggle for many students. Games by their nature require active participation and reward mastery, lending naturally to the framework of active learning. In this study, we designed and evaluated the efficacy of a lab activity using a game where strategy hinges on sums of dice to teach about linear combinations of independent random variables. We found that both activities lead to improved understandings of course concepts, but the dice game provided increased student engagement and interest. 相似文献

With the creation of interactive tasks that allow students to explore spatial ways of knowing in conjunction with their other ways of knowing the world, we create a space where students can make sense of information as they organize these new ideas into their already existing schema. Through the use of a Common Online Data Analysis Platform (CODAP) and data from Public Use Microdata Areas (PUMA), students can explore the communities in which they live and work, critically examining opportunities and challenges within a defined space. 相似文献

The aim of this study was to determine whether subtest scatter might be an indicator of learning disabilities (LDs), psychopathology, or of both, in a sample of normal adolescents. Subjects completed the WISC‐III and the MMPI‐A and then their scores for the WISC‐III subtests, verbal scatter (VScatter), performance scatter (PScatter), full scale scatter (FScatter) scores, perceptual organisation factor (PO), and the SCAD profiles were calculated. The MMPI‐A was scored and the clinical scales were extracted. The hypothesis that subtest scatter is associated with LDs was generally not supported. There was a relationship between subtest scatter and psychological disturbance in adolescent males, however the results for females were less clear. Further, high PScatter in adolescent males was associated with an MMPI‐A codetype 4‐2/2‐4, indicating tendencies toward depressive features, delinquent behavior, and possibly substance abuse, tendencies which are likely to lead to school failure. © 1999 John Wiley & Sons, Inc. 相似文献

This paper summarizes the findings from a K-6 professional development program that emphasized scientific inquiry and nature
of science within the theme of scientific modeling. During the 2-week summer workshop and follow up school year workshops,
the instruction modeled a 5-E learning cycle approach. Pre and posttesting measured teachers’ views of nature of science,
inquiry, and scientific modeling. Teachers improved their views of nature of science (NOS) and inquiry by including scientific
modeling in their definitions of how scientists work, the empirical nature of science, and the role of observations and inferences
in science. Their definitions of science expanded from a knowledge-based orientation to a process-based orientation. Teachers
added the use of mathematical formulas to their views of scientific modeling. Using scientific modeling as the central theme
was effective in providing positive influence on teachers’ views of inquiry and NOS. 相似文献

The generality of a multilevel factorial model of social competence (SC) for preschool children was tested in a 5‐group, multinational sample (N = 1,540) using confirmatory factor analysis. The model fits the observed data well, and tests constraining paths for measured variables to their respective first‐order factors across samples also fit well. Equivalence of measurement models was found at sample and sex within‐sample levels but not for age within sample. In 2 groups, teachers’ ratings were examined as correlates of SC indicators. Composites of SC indicators were significantly associated with both positive and negative child attributes from the teachers’ ratings. The findings contribute to understanding of both methodological and substantive issues concerning SC in young children. 相似文献

Interindividual Differences in Neonatal Imitation and the Development of Action Chains in Rhesus Macaques 总被引:1,自引:0,他引:1

The capacity to imitate facial gestures is highly variable in rhesus macaques and this variability may be related to differences in specific neurobehavioral patterns of development. This study evaluated the differential neonatal imitative response of 41 macaques in relation to the development of sensory, motor, and cognitive skills throughout the 1st month of life. The results show that infants who imitate facial gestures display more developed skills in goal-directed movements (reaching–grasping and fine hand motor control) than nonimitators. These differences might reflect, at least in part, the differential maturation of motor chains in the parietal and motor cortices, which partly overlap with those of the mirror neuron system. Thus, neonatal imitation appears to be a predictor of future neurobehavioral development. 相似文献

ObjectivesThis research explores the relationship between hypothesized protective factors and outcomes for children investigated for maltreatment.MethodsUsing data from the National Survey on Child and Adolescent Well-Being (NSCAW), we ran logistic regression models to examine the relationship between hypothesized protective factors (social competence, adaptive functioning skills, and peer relationships) and outcomes (externalizing behavior, internalizing behavior, reading competence).ResultsFor each hypothesized protective factor, we found variation in individual scores and sample mean scores at the lower end of the scales, indicating that these children fare worse than most children. However, many children experienced large changes in their individual scores over time suggesting that children can and do improve on these hypothesized protective factors. In examining the relationship between hypothesized protective factors and outcomes, children with higher levels of social competence were significantly more likely to be in the normal range for both externalizing and internalizing behaviors. Children with higher mean adaptive functioning skills were more likely to be in the normal range for both externalizing behavior and reading competence. The positive nature of the child's peer relationships was also related to externalizing behavior and reading competence.ConclusionsOverall, our analyses support the idea that social competence, adaptive functioning skills, and peer relationships are related to outcomes for children investigated for maltreatment. While further research is needed to establish a causal link, this work identifies three individual-level hypothesized protective factors as potential sources of variation in outcomes.Practice implicationsTo prevent or alleviate the harmful consequences maltreatment, it is necessary to understand factors that help children move beyond poor outcomes. Our analyses suggest that a strong relationship exists between a child's social competence, adaptive functioning skills and positive peer relationships and select outcomes three years after being investigated for maltreatment. With these individual-level protective factors related to more positive outcomes, it suggests that intervening to increase protective factors could improve outcomes for maltreated and at-risk children. 相似文献
