In an experiment designed to investigate individual differences in learning from written materials preceded by advance organizers, 89 fourth-grade subjects were randomly assigned to treatment conditions in which programmed material on insects was preceded by one of three introductory passages containing: (1) higher level generalizations and specific examples; (2) higher level generalizations without examples; or (3) a control passage. Membership in treatment groups was determined by random assignment. Criterion performances were immediate and delayed posttest performance and errors during instruction. Analysis of variance results of treatment effects showed that the three treatments were about equally effective in terms of promoting retention and program errors. Simple regression analysis of Aptitude × Treatment interactions disclosed that Otis-Lennon IQ scores interacted significantly with instructional treatments for program errors showing a negative relationship between IQ scores and the degree of structure provided by the advance organizers. 相似文献

Effects of an Attachment‐Based Intervention on Child Protective Services–Referred Mothers' Event‐Related Potentials to Children's Emotions 下载免费PDF全文
This study examined the neurobiology of maternal sensitivity to children's emotions among mothers involved with Child Protective Services (CPS) and low‐risk comparison mothers (Mage = 31.6 years). CPS‐referred mothers participated in the Attachment and Biobehavioral Catch‐up (ABC) intervention or a control intervention. Mothers' event‐related potentials (ERPs) were measured while they categorized images of children with crying, laughing, and neutral expressions. CPS‐referred ABC mothers (n = 19) and low‐risk comparison mothers (n = 30) showed a larger enhancement of ERP responses for emotional faces relative to neutral faces than CPS‐referred control mothers (n = 21). Additionally, the magnitude of ERP responses to emotional faces was associated with observed maternal sensitivity. Findings add to the understanding of the neurobiology of deficits in parenting and suggest that these deficits are changeable through a parenting intervention. 相似文献

What is the difference between NAEP anchor levels and achievement levels? How are the processes different for creating these levels? What points of controversy surround use of these levels for reporting achievement? Will having standards for NAEP promote improvement of public education? 相似文献

This paper examines issues in the debate on quality assurance in the English system of higher education as they have developed between the Further and Higher Education Act of 1992 and the review proposed by the Secretary of State at the end of 1994. The main focus is on the development by the Higher Education Funding Council for England (HEFCE) of its method of quality assessment and the call for the restoration of 'self-regulation' in such matters to the institutions. The role of the institutions in developing the methods adopted by the Funding Council is outlined, and the chief criticisms of its effects evaluated. The paper concludes by reviewing options for change in the immediate future and the conditions that will have to be met. It is argued that systems could undoubtedly be improved, but that key elements of 'self-regulation' have already been won in the continuation of external peer review. 相似文献

This paper outlines the electronic ‘short loan’ collection of high-demand journal articles developed by Project ACORN (Access to Course Readings via Networks) (1). It summarises some preliminary findings on the volume and type of use made of the service, and users' reactions to it. Factors affecting non-use are also presented. Issues and developments for the future are discussed in the light of experiences to date. 相似文献

Using the theoretical frameworks of Erving Goffman and Michael Lipsky, an example of school library staff and student interactions is examined, using functional discourse analysis to reveal how practice is produced as a clerical control routine which upholds institutional authority over users, rather than legitimate service work. The study, which consists of a single interaction between a middle school library clerk and a young adolescent with overdue books, is an example of what Goffman calls a “remedial interchange” in which the clerk, with the use of the library's computer, identifies the student's “offense” of keeping books overdue, despite repeated notices. Upon admission of the student's virtual transgression, the clerk provides an “offering” to hold his desired books until he returns the others, thus redressing the balance of the interaction while still retaining asymmetrical institutional control over the student. 相似文献
