High-Quality Preschool: The Socioeconomic Composition of Preschool Classrooms and Children's Learning

Research Findings: As policymakers expand access to preschool, the sociodemographic composition of preschool classrooms will become increasingly important. These efforts may create programs that increase the concentration of children from low-income families or, alternatively, foster the creation of socioeconomically diverse preschool classrooms. What effect the creation of such contexts would have on very young children remains unclear. Using multilevel methods and data on 2,966 children in 704 prekindergarten classrooms, this study explores the relationship between socioeconomic classroom composition and children's social and cognitive development. The results indicate positive associations between the mean socioeconomic status (SES) of the class and children's receptive language, expressive language, and mathematics learning, regardless of children's own sociodemographic backgrounds and the characteristics of their classrooms. However, the analyses indicate no association between the development of social competence and class mean SES. Practice or Policy: The links between classroom SES and language and mathematics development were comparable in size to those associated with instructional quality and even children's own SES. Neither structural nor instructional characteristics of prekindergarten classrooms explained these relationships, suggesting the possibility of direct peer effects. The findings indicate that the composition of children's classrooms should be considered an important aspect of preschool quality.     

How Haptics and Drawing Enhance the Learning of Anatomy

Students’ engagement with two-dimensional (2D) representations as opposed to three-dimensional (3D) representations of anatomy such as in dissection, is significant in terms of the depth of their comprehension. This qualitative study aimed to understand how students learned anatomy using observational and drawing activities that included touch, called haptics. Five volunteer second year medical students at the University of Cape Town participated in a six-day educational intervention in which a novel “haptico-visual observation and drawing” (HVOD) method was employed. Data were collected through individual interviews as well as a focus group discussion. The HVOD method was successfully applied by all the participants, who reported an improvement of their cognitive understanding and memorization of the 3D form of the anatomical part. All the five participants described the development of a “mental picture” of the object as being central to “deep learning.” The use of the haptic senses coupled with the simultaneous act of drawing enrolled sources of information that were reported by the participants to have enabled better memorization. We postulate that the more sources of information about an object, the greater degree of complexity could be appreciated, and therefore the more clearly it could be captured and memorized. The inclusion of haptics has implications for cadaveric dissection versus non-cadaveric forms of learning. This study was limited by its sample size as well as the bias and position of the researchers, but the sample of five produced a sufficient amount of data to generate a conceptual model and hypothesis.     

The education welfare service: the case for a review in England

The only major review of the education welfare service (EWS) took place in 1973 when the role and responsibilities of the service were very different from those of today. Recent legislative changes, the influence of the Children Act 2004 and revised public needs of the service, including new multidisciplinary and interdisciplinary frameworks, suggest that an up‐to‐date review would be timely. It may also help to professionalise the service in a number of different ways, something which is long overdue. This paper provides both the rationale and evidence for making the case for a major review of the EWS based on a reading of all key relevant documents and participation in a range of local and national evaluations on the role of the EWS in England and Wales. The major issues which need to be reviewed are identified and a way forward is suggested.     

Best entry points for structured document retrieval—Part II: Types,usage and effectiveness

Structured document retrieval makes use of document components as the basis of the retrieval process, rather than complete documents. The inherent relationships between these components make it vital to support users’ natural browsing behaviour in order to offer effective and efficient access to structured documents. This paper examines the concept of best entry points, which are document components from which the user can browse to obtain optimal access to relevant document components. It investigates at the types of best entry points in structured document retrieval, and their usage and effectiveness in real information search tasks.     

Informed Consent in the Study of On-Line Communities: A Reflection on the Effects of Computer-Mediated Social Research

In studying on-line communities, researchers must consider the unique environmental factors involved in order to minimize potential harm to human subjects. In particular, the often commented upon disinhibiting effect of computer-mediated communication can encourage people to agree to or even insist on a kind of public exposure by which they may eventually be harmed. On the Internet, where perceptions of interpersonal affect and effects may be obscured by the nature of the medium itself, care must be taken to guard against not only any increased tendency for researchers to objectify subjects, but also the tendency for subjects to underestimate the potential consequences of consent. The criteria for informed consent that may be sufficient in face-toface research environments are not necessarily so in a medium in which subjective experience is easily objectified and information is easily devalued.     

Young People's Conceptions of Environment: A phenomenographic analysis

Environmental education in schools is an important strategy in achieving environmental improvement. However, it needs to be based on children's understandings of environment rather than on assumptions of what children know and believe. This paper reports on a research project where school children's answers to a question 'I think the term/word environment means ' were analysed using the qualitative research method of phenomenography. Six distinct conceptions were isolated, ranging from the least sophisticated--environment as a place--to the most inclusive and expansive--environment and people in a relationship of mutual sustainability. An important qualitative difference was found between conceptions that treat the environment as an object and relational conceptions. The implications of these findings for environmental education are discussed.     

The veridicality of punitive childhood experiences reported by adolescents and young adults

OBJECTIVE: The primary goal of the present research was to determine whether retrospective reports of childhood disciplinary experiences and perceptions of that discipline correspond to actual childhood events and whether the accuracy of that report was influenced by the affective state of the respondent. METHOD: Eighty-three adolescent and young adult males completed a retrospective measure of physical child maltreatment, Assessing Environments (AEIII), and the Brief Symptom Inventory (BSI). As children the participants had been observed naturalistically in their homes interacting with their parents an average of 10 years earlier. RESULTS: Analyses were consistent with the hypothesis that both current mood and actual observations of parent-child interactions during childhood predict self-reported recollections of childhood maltreatment by one's parents. Further the veridicality of such recollections appears to depend upon the objective specificity versus the perceptive nature of the questions used to elicit the recollections. CONCLUSIONS: The findings suggest that assessment instruments suitable for obtaining information regarding earlier childhood victimization must utilize behaviorally specific items. Thus, items that are either global or intimate a normative comparison should be avoided.
