Children's Use of Metaphorical Language: an experimental study of the technique of guided fantasy in the secondary school English classroom

The technique of guided fantasy is being used in schools to stimulate creative writing. Children are given a planned opportunity to imagine a particular scene and then to use this experience as a stimulus for related imaginative writing. This study attempts to examine the apparent superiority of this technique over more conventional methods. Thirty third‐year pupils produced work under two contrasting conditions and the compositions were then assessed against a range of linguistic criteria, including the number and novelty of images produced, the number of words per essay, absolute vocabulary, unusual vocabulary, unspecific vocabulary and the degree of adverbial and adjectival modification and repetition. Additional criteria were time spent on the task and the number and quality of statements of feeling. The guided‐fantasy stimulus, however, did not produce the expected results. Possible explanations of this are discussed through the literature on children's learning.     

Family Structure and Psychosocial Correlates among Urban African-American Adolescent Males

Substance use and delinquency, psychological well-being, and social support were compared across 5 family constellations among 254 urban African-American adolescent males. Single-mother, stepparent, both parents, mother with extended family, and extended family only households were studied. The only differences found were that youth living in single-mother households reported more parental support than other youth. Relationships with father and male role models were also studied and related to several psychosocial outcomes. The results challenge the assumptions that single African-American mothers are alone in providing support to their sons and that fathers' absence results in no significant relationship.     

Using an Approximate Chi-Square Statistic to Test the Number of Dimensions Underlying the Responses to a Set of Items

An approximate χ² statistic based on McDonald's (1967) nonlinear factor analytic representation of item response theory was proposed and investigated with simulated data. The results were compared with Stout's T statistic (Nandakumar & Stout, 1993; Stout, 1987). Unidimensional and two-dimensional item response data were simulated under varying levels of sample size, test length, test reliability, and dimension dominance. The approximate χ² statistic had good control over Type I errors when unidimensional data were generated and displayed very good power in identifying the two-dimensional data. The performance of the approximate χ² was at least as good as Stout's T statistic in all conditions and was better than Stout's T statistic with smaller sample sizes and shorter tests. Further implications regarding the potential use of nonlinear factor analysis and the approximate χ² in addressing current measurement issues are discussed.     

Development and validation of two scales to measure elaboration and behaviors associated with stewardship in children

This investigation examines the development of two scales that measure elaboration and behaviors associated with stewardship in children. The scales were developed using confirmatory factor analysis to investigate their construct validity, reliability, and psychometric properties. Results suggest that a second-order factor model structure provides the best fit. This model produced: (1) a stewardship elaboration scale measuring interest and cognitive engagement in stewardship issues, and (2) a stewardship behavior scale measuring in-park, community, and home behaviors. These scales will be useful for evaluating environmental educational programs focused on environmental and park stewardship. The scales may also help researchers assess whether environmental education results in participants elaborating on persuasive messaging, thereby increasing the likelihood that behavioral intentions leading to behavior change will occur.     

Current Tobacco-Smoking and Neural Responses to Infant Cues in Mothers

Objective. Smoking has a detrimental impact on maternal physical health and exposes children to secondhand smoke, but the extent to which it affects maternal brain and behavior is not well-known and may have implications for parent and child development. We examined how current smoking status might relate to maternal neural responses to infant cues using event-related potentials. Design. Current smoking (n = 35) and non-smoking (n = 35) mothers viewed photographs of emotional infant faces while electroencephalography was simultaneously recorded. Results. The latency of the face-specific N170 event-related potential component was delayed in smoking mothers compared to non-smoking mothers, and the P300 was differentiated by smoking status. Conclusions. Postpartum smoking is associated with event-related potential measures that may reflect modulation of infant face perception in motherhood.     

Learning via direct and mediated instruction by deaf students

Four experiments investigated classroom learning by deaf college students receiving lectures from instructors signing for themselves or using interpreters. Deaf students' prior content knowledge, scores on postlecture assessments of content learning, and gain scores were compared to those of hearing classmates. Consistent with prior research, deaf students, on average, came into and left the classroom with less content knowledge than hearing peers, and use of simultaneous communication (sign and speech together) and American Sign Language (ASL) apparently were equally effective for deaf students' learning of the material. Students' self-rated sign language skills were not significantly related to performance. Two new findings were of particular importance. First, direct and mediated instruction (via interpreting) were equally effective for deaf college students under the several conditions employed here. Second, despite coming into the classroom with the disadvantage of having less content knowledge, deaf students' gain scores generally did not differ from those of their hearing peers. Possible explanations for these findings are considered.     

How Instruction Influences Conceptual Development: Vygotsky's Theory Revisited

Although current interpretations of Vygotsky's theory largely assume that instruction pushes development, the issue of how this occurs has yet to be clarified. For example, the notion of “zone of proximal development” has aroused strong disagreement, and the common conceptualization of the notion of “nonspontaneous concept” has been widely recognized as unsatisfactory. This article proposes a new interpretation of Vygotsky's theory of cultural development, closely based on Vygotsky's writings, that clarifies why and how instruction pushes development and resignifies the notions of zone of proximal development and nonspontaneous concept. The article introduces important nuances into the widely held interpretations of Vygotsky's theory and discusses some of the implications of these nuances for research and practice in educational psychology.     

Emotion regulation in the brain: conceptual issues and directions for developmental research

Emotion regulation cannot be temporally distinguished from emotion in the brain, but activation patterns in prefrontal cortex appear to mediate cognitive control during emotion episodes. Frontal event-related potentials (ERPs) can tap cognitive control hypothetically mediated by the anterior cingulate cortex, and developmentalists have used these to differentiate age, individual, and emotion-valence factors. Extending this approach, the present article outlines a research strategy for studying emotion regulation in children by combining emotion induction with a go/no-go task known to produce frontal ERPs. Preliminary results indicate that medial-frontal ERP amplitudes diminish with age but become more sensitive to anxiety, and internalizing children show higher amplitudes than noninternalizing children, especially when anxious. These results may reflect age and individual differences in the effortful regulation of negative emotion.     

Learning to Deal with Social Factors as a Goal in the Education of Engineers

One of the challenges engineers face is how to deal with the combination of scientific‐technological and social factors in the development and implementation of new technologies. To prepare student engineers for this there are two options: (a) train a special type of engineer, who has had a combination of engineering and social science courses; and (b) teach the ‘normal’ engineers to get a good feeling for the relevance of social factors to their work. Both types of training are offered at the Eindhoven University of Technology. In this article, we describe the results of a study into the way student engineers in their master's thesis struggle with the integration of social factors in their engineering work. A programme of guidelines for doing this in a more sophisticated way has been developed on the basis of these experiences and of literature in the field of technology assessment and design methodology.
