Children''s Use of Anatomically Detailed Dolls to Recount an Event   总被引:2,自引:0,他引:2  
The use of anatomically detailed dolls in child sexual abuse investigations has raised several controversial issues related to important theoretical questions in developmental psychology. The present study was designed to examine some of these issues in a methodologically sound experiment. 80 3- and 5-year-old children experienced a social interaction with a male confederate and were later tested under 1 of 4 recall conditions: reenactment with anatomically detailed dolls, reenactment with regular dolls, free recall with visual cues, or free recall without visual cues. The children were also asked a variety of specific and misleading questions, some of them dealing with acts associated with abuse ("He took your clothes off, didn't he?"). Both anatomically detailed and regular dolls along with other props aided 5-year-olds more than 3-year-olds in recounting the event. To use increased rather than decreased age differences. Anatomically detailed dolls did not foster false reports of abuse. Overall, 3-year-olds were more suggestible than 5-year-olds. The findings have implications for children's testimony in child abuse cases and for psychological theories concerning the effects of stimulus support on children's memory.  相似文献

Three tests of receptive language were administered to thirty children enrolled in regular, gifted, and learning disabled‐gifted programs. Analyses of variance indicated that the Token Test for Children differentiated the learning disabled‐gifted children and the Verbal Absurdities Subtest of the Detroit Tests of Learning Aptitude differentiated the gifted children from the other two groups.  相似文献

Preschool children's reasoning about ability   总被引:3,自引:0,他引:3  
Young children's reasoning about ability was investigated among 155 preschoolers (M = 4 years, 10 months) across 3 studies. Results suggest that preschoolers are sensitive to mental state information when making judgments about another child's ability: They judged a child who finds a task easy to be smarter than one who finds the same task hard. Systematic patterns of errors on recall tasks suggest that preschoolers perceive positive correlations between (a) exerting effort and experiencing academic success, and (b) being nice and having high academic ability. Results from a comparison group of forty 9- to 10-year-olds (M = 9 years, 10 months) suggest that the preschool findings generally reflect emerging patterns of reasoning about ability that persist into later childhood, but that the perceived correlations between high effort and academic outcomes and between social and academic traits diminish with age.  相似文献

The rapid pace of development is bringing advanced technologies to the World Wide Web (WWW), and, as a result, schools have access to new tools for science investigations. In this exploratory study, we investigated how an educational experience organized around students' use of a WWW‐controllable atomic force microscope (AFM) influenced students' understandings of viruses. The context for the study was a weeklong unit on viruses for two high school biology classes which incorporated student use of the WWW controllable AFM. We also investigated how the haptic (involving kinesthetics and touch) experiences afforded by this tool might influence students' knowledge of viruses, microscopy, and nanometer scale. Fifty students from two high school biology classes participated in a series of instructional activities and pre‐ and postassessments (knowledge test, opinion questionnaire, and interviews). Results showed that students' understandings of microscale, virus morphology, and dimensionality changed as a result of the experiences. Students' conceptions moved from a two‐dimensional textbook‐like image of a virus to a three‐dimensional image of an adenovirus. The results of this preliminary study suggest that the use of the technology as a tool for learning about morphology of materials too small to see may be beneficial. © 2003 Wiley Periodicals, Inc.

The National Science Education Standards (National Research Council 1996, National science education standards. Washington, DC: National Academy Press) and various other national and state documents call for teachers who possess science content knowledge, employ an inquiry approach in teaching, and engage in reflective practices. This paper describes a rationale for choosing particular recommendations to implement and how we incorporated those as we revised our elementary science education program. An analysis of the impact of the reformed inquiry-based content courses revealed that students who take more than one reformed content course improve their science content knowledge and efficacy towards teaching science significantly more than students who take fewer courses.  相似文献

OBJECTIVES: Since the late 1980s, there has been a strong theoretical focus on psychological and social influences of perpetration of child sexual abuse. This paper presents the results of a review and meta-analysis of studies examining risk factors for perpetration of child sexual abuse published since 1990. METHOD: Eighty-nine studies published between 1990 and April of 2003 were reviewed. Risk factors were classified into one of the following six broad categories: family factors, externalizing behaviors, internalizing behaviors, social deficits, sexual problems, and attitudes/beliefs. Sex offenders against children (SOC) were compared to three comparison groups identified within the 89 studies: sex offenders who perpetrated against adults (SOA), non-sex offenders, and non-offenders with no history of criminal or sexual behavior problems. RESULTS: Results for the six major categories showed that SOC were not different from SOA (all d between -.02 and .14) other than showing lower externalizing behaviors (d=-.25). Sex offenders against children were somewhat different from non-sex offenders, especially with regard to sexual problems and attitudes (d=.83 and .51). Sex offenders against children showed substantial differences from non-offenders with medium sized effects in all six major categories (d's range from .39 to .58). CONCLUSION: Child sex offenders are different from non-sex offenders and non-offenders but not from sex offenders against adults. PRACTICE IMPLICATIONS: This study suggests that the presence of general risk factors may lead to a variety of negative behavioral outcomes, including the perpetration of child sexual offending. Family factors were strongly related to the perpetration of child sex offending (vs. non-sexual offending or non-offending) and may be valuable intervention points for interrupting the development of child sex offending, as well as other negative behaviors. Other potential points for intervention may focus on the development of appropriate social and emotional skills that contribute to sexual offending.  相似文献

In this article, we describe an innovative capstone course for preservice K-8 teachers integrating action research and a unifying theme in science (AAAS in Science for all Americans. Oxford University Press, New York, 1989; NRC in National science education standards. National Academy Press, Washington, DC, 1996). The goals of the capstone course are to increase student knowledge of the unifying theme, improve written communication skills, and introduce students to educational research. We provide evidence that each of these goals is met. Student growth in theme knowledge is demonstrated through concept maps, questionnaires, and previously reported assessments. Improved writing ability is demonstrated using the spelling and grammar checking feature of Microsoft Word. The analysis of action research reports demonstrates that students are able to connect their action research project results to previous research.  相似文献

This study investigated students' with visual impairment concepts about linear size and scale. Specifically the study examined the accuracy of students' concepts over many orders of magnitude as well as experiences students have had in and out‐of‐school learning about size and scale. The results of assessments of 17 students with visual impairment were compared to those of students with normal sight. The study showed that students with visual impairment were most accurate for measurements in the human scale and were least accurate with very large and very small scales that cannot be directly experienced. However, when compared to students with normal sight, students with visual impairment were more accurate at large and small scales than their normally sighted peers. © 2009 Wiley Periodicals, Inc.
