动态测验对“数学学习困难”儿童的进一步甄别

本研究意在考查动态测验对数学学习困难儿童作进一步程度区分的有效性。以传统且常用的数学学习困难鉴别方式和标准选取30名四年级数学学习困难儿童为实验组,30名同年级智力匹配儿童为对照组,以Swanson认知加工测验(S-CPT)的4个子测验为测量工具对被试进行动态测验。结果发现：(1)在传统数学学习困难鉴别方式的基础上,动态测验的“潜在认知能力”指标可以对儿童数学成绩增加19%的预测力;(2)以“潜在认知能力”指标为依据能够将数学学习困难儿童进一步区分为“发展落后”和“发展缺陷”两个水平;(3)“发展落后”儿童一年内数学成绩发生了增长性变化,与正常儿童水平相当,而“发展缺陷”儿童的数学成绩没有变化。研究证实关注潜能指标的动态测验范式在快速、准确甄别数学学习困难儿童上具有独特效用。

编程学习与儿童认知发展关系的探讨

随着编程课程渗入到学前教育当中,研究者开始探究编程学习对学前儿童认知发展的影响及机制。本文通过对已有文献的分析发现,编程学习可显著提升学前儿童的认知控制、工作记忆等基础认知能力,并促进问题解决、创造力等高阶认知能力的发展,还对数学与语言学习绩效具有提升效果。未来早期编程学习研究还需从设计、工具、研究系统性和其他影响因素等层面进行变革,揭示编程学习影响认知发展的机制,为开展儿童编程教育提供科学依据。     

学习不良儿童与一般儿童认知发展、学习动机和家庭资源的比较

运用认知测验法和问卷法,综合考察了167名学习不良儿童和161名一般儿童的认知发展、学习动机和家庭资源的特点,结果表明:与一般儿童相比,学习不良儿童认知发展的速度比较缓慢,对于较简单的认知能力,其年龄差异显着,而对于较复杂的认知能力,年龄差异较小;学习不良儿童的学习动机显着低于一般儿童,但其学习动机与其认知水平呈显着的正相关;学习不良儿童的家庭资源配置与一般儿童相比差异明显.     

儿童逻辑关系认知发展的实验研究

通过追踪研究和横断研究相结合的方法研究７岁、９岁和１２岁儿童的逻辑关系认知能力的发展。结果表明：儿童的认知成绩随着年龄的增长而提高,不同项目间差异很大,而且不同实验项目有不同的发展速度。儿童间的个别差异也很大,这主要与儿童的家庭教育程度以及城市与郊区不同学校教育条件等因素有关,并且儿童的逻辑关系认知能力与儿童的学习能力,学习成绩以及儿童的智力水平有很高的相关。另外儿童的物理逻辑认知并非都按固定不变的顺序发展。

Cognitive strategies and strategic learning. The socio-instructional approach

Recent developmental studies have focused on children's learning strategies and on the socio-instructional dynamics that foster strategic learning. The introduction of Vygotsky's concept of the zone of proximal development has been central to this research effort. Zone theory is discussed in the context of traditional cognitive strategies research and in terms of its practical applications.

Generative connectionist networks and constructivist cognitive development

This article presents a novel computational framework for modeling cognitive development. The new modeling paradigm provides a language with which to compare and contrast radically different facets of children's knowledge. Concepts from the study of machine learning are used to explore the power of connectionist networks that construct their own architectures during learning. These so-called generative algorithms are shown to escape from Fodor's (1980) critique of Constructivist development. We describe one generative connectionist algorithm (cascade-correlation) in detail. We report on the successful use of the algorithm to model cognitive development on balance scale phenomena; seriation; the integration of velocity, time, and distance cues; prediction of effect sizes from magnitudes of causal potencies and effect resistances; and the acquisition of English personal pronouns. The article demonstrates that computer models are invaluable for illuminating otherwise obscure discussions.     

The role of collaborative planning in children's source-monitoring errors and learning.

The aim of this research was to provide empirical evidence for a cognitive process that may contribute to children's learning from another person. A cornerstone of Vygotsky's sociocultural theory is that knowledge is internalized from others; however, the cognitive processes that support this transformation are underspecified. In a series of three studies, kindergarten children (mean age 5 years 8 months) participated in a categorization task with an adult in several collaborative and noncollaborative conditions and then were tested on their memory of who had performed which actions in the task. After the memory task, children were asked to recategorize the items on their own. Source-monitoring patterns and children's learning varied across conditions according to predictions. A measure of recoding was related to children's planning language that, in turn, predicted learning among the children. The results suggest that one process that contributes to children's internalization of knowledge may involve recoding of agent information and that recoding can be indexed by source-monitoring performance.     

Implications of Timing of Maternal Depressive Symptoms for Early Cognitive and Language Development

: Statistically, women, particularly pregnant women and new mothers, are at heightened risk for depression. The present review describes the current state of the research linking maternal depressed mood and children's cognitive and language development. Exposure to maternal depressive symptoms, whether during the prenatal period, postpartum period, or chronically, has been found to increase children's risk for later cognitive and language difficulties. The present review considers both the timing of maternal depression and the chronicity of mothers' depression on children's risk for cognitive and language delays. Infancy is frequently identified as a sensitive period in which environmental stimulation has the potential to substantially influence children's cognitive and language development. However, children's exposure to chronic maternal depression seems to be associated with more problematic outcomes for children, perhaps because depression interferes with mothers' ability to respond sensitively and consistently over time. Consistent with this expectation, interventions targeting parenting practices of depressed mothers have been found to increase children's cognitive competence during early childhood. The current review provides a synthesis of the current state of the field regarding the association between maternal depression and children's cognitive and language development during early childhood.

Cognitive Development Masks Support for Attributional Style Models of Depression in Children and Adolescents

Attributional style models of depression in adults (Abramson et al. 1989, 1978) have been adapted for use with children; however, most applications do not consider that children's understanding of causal relations may be qualitatively different from that of adults. If children's causal attributions depend on children's level of cognitive development, then support for attributional models of depression in young people will vary with cognitive development. In this paper, a new measure of cognitive development, the Peabody Causal Reasoning Test (PCRT), is introduced to assess children's understanding of ability versus effort, task difficulty, and luck as causal factors. Analyses revealed that in 8- to 16-year-old children, failure to control for level of cognitive development suppressed empirical support for cognitive diathesis-stress models of depression. Statistically controlling for measures of cognitive development strengthened support for this model.     

Does learning behavior augment cognitive ability as an indicator of academic achievement?

Measures of cognitive ability have a rich history of accounting for meaningful levels of achievement variance. In contrast to other student characteristics, however, they are somewhat limited in terms of their intervention relevance and treatment validity. Alternatively, children's observable learning behaviors are believed to enhance both treatment validity and the predictions afforded by cognitive ability. This study examined student learning behaviors in the context of cognitive ability and academic achievement. Three structural models were evaluated on a sample of 1304 students ranging in age from 6 to 17 years. Results supported the unique relationship between learning behavior and academic achievement, beyond cognitive ability. Multi-group structural equation modeling (SEM) analysis revealed that these findings were invariant across groups differing by gender and ethnicity. These findings are consistent with previous observations that children's behavioral features in learning situations will supplement the outcome-oriented standardized tests of cognitive ability.     

Male teacher effects on young children: A theoretical and empirical consideration

The argument has been frequently made that an increase in the number of male teachers working at the early school levels would reduce the number of school-related problems for boys. This argument is evaluated in the context of two major theories of sex-role development, the social learning and cognitive developmental theories, and the results of an examination of the studies of children's performance and development in relation to teacher's gender. The hypothesis that male teachers reduce boys' problems in school does not receive much support empirically or theoretically.This work was supported by a grant from the Quebec Department of Education to the first author.
