Identification and reporting of child maltreatment by Head Start personnel: attitudes and experiences 总被引:1,自引:0,他引:1
A two-part questionnaire was administered to 143 Head Start personnel in order to determine how personal characteristics of the Head Start workers and the characteristics of the families they serve, affect the identification and reporting of child maltreatment. Of additional interest was whether some forms of maltreatment, once identified, would be more likely to be reported than other forms of maltreatment. The results support the efficacy of educational programs in child maltreatment for increasing the identification and reporting of maltreatment by workers. They also indicate that there are complex interactions between certain characteristics of the reporter (e.g., educational level) and prior training in maltreatment identification. Finally, neglect, although more frequently identified by the workers, appears to be least likely of all forms of maltreatment to be reported to official sources. Results are discussed in light of their implications for future research and practical application. 相似文献

The robustness of the effect of precise elaborations on memory and the relationship of these effects to metacognitions about
learning was investigated in two studies. Twenty-six naive experimenters administered prepared tasks to 130 subjects. Participants
rated the comprehensibility of each sentence as it was read. An unexpected cued-recall test with a confidence rating for each
answer given was administered, followed by rating the ease of learning the types of items used in three treatments: precisely
elaborated, imprecisely elaborated, and unelaborated base sentences. Both studies resulted in very similar findings: Memory
for precise elaborations was 50% greater than for either imprecisely elaborated or unelaborated statements. Comprehension
ratings of the three sets of statements were not significantly different. Confidence ratings of correctly answered items were
significantly higher than of incorrectly answered items. 相似文献

The concepts of randomness and variation are pervasive in science. The purpose of this study was to document how post-secondary life science students explain randomness and variation, infer relationships between their explanations, and ability to describe and identify appropriate and inappropriate variation, and determine if students can identify sources of variation. An instrument designed to test statistical concepts was administered to 282 college students from three universities, ranging from introductory non-science majors to science graduate students. Students readily distinguished between causes of variation. A naïve no-pattern concept of randomness persisted from first-year non-science majors to senior-level science majors, contributing to incorrect responses on the variation instrument. Students’ expressions of randomness were better predictors of performance on the variation instrument than their expressions of variation. It is argued that inclusion of everyday language uses of randomness in instruction can bridge the gap between vernacular and scientific uses of this term. 相似文献

In this paper we continue our search for a socially responsible science education by an examination of the trends in the Science,
Technology and Society movement. These trends reflect differing ideological perspectives and result in courses which serve
different ends. We identify two major flaws in the movement that inhibits the realization of a schooling in science dedicated
to democracy. We propose skills necessary for citizens to participate in debate over issues surrounding the impact of science
and technology on society and a teaching stategy to help develop them.
Specializations: social responsibility and the curriculum, ideology and comparative science education. 相似文献

Widely cited experiments on optimal foraging have used bivalued distributions as representing environmental stochasticity, characterizing these in terms of their arithmetic means. In contrast, research on free-operant choice has established that organisms prefer variable patterns of food delivery, relative to fixed patterns with the same mean values. To explore such departures from linear averaging, specifically with respect to bivalued alternatives, pigeons were given choices between a fixed-ratio (FR) schedule of food delivery that required 15, 30, or 60 responses and bivalued variable-ratio schedules with an arithmetic mean of 60,5 or 60, A bivalued schedule of 1 and 120 was preferred almost exclusively over each of the FR values. With a bivalued schedule of 15 and 105, there was a shift of preference, most notably in the FR-15 condition, but in no case was linear averaging a good predictor of the birds’ choices. Geometric averaging fared better, but even this failed to represent the apparent salience of the minimum value of the bivalued schedule in some conditions. 相似文献

Competence to work in schools is an important dimension of professional competence, although it is often a neglected dimension of teacher development. This article reports a qualitative study that examined student teachers’ learning experiences in initial teacher education (ITE) in relation to competence to work in schools. In-depth interviews were conducted with 12 student teachers on an undergraduate ITE programme in Hong Kong. The findings of the study show that competence to work in schools is characterised by student teachers’ deep contextualised learning. In addition, it offers a deeper understanding of this competence in the ITE context by identifying its three facets, namely understanding of the micro-political realities of schools, social capital building and social strategies. The study provides insights for ITE and schools to support student teachers’ development of their competence to work in schools, including the design of ITE curricula, ITE processes and co-curricular activities in undergraduate studies. Moreover, it suggests the importance of developing schools as growth-fostering and positive micro-political sites for ITE fieldwork and teacher induction. 相似文献

This study was designed to explore the influence of changes in children's knowledge on earlier constructed memories. Kindergartners' (N = 102) recall of a series of stories was examined as a function of their interpersonal knowledge about the main story character. Children's knowledge about the protagonist was manipulated prior to presentation of the stories, and the effects of their impressions on story recall were examined. A change in some of the children's impressions was then promoted, and the impact of this second knowledge manipulation on recall of previously heard stories was assessed. The results indicated that children's story recall was affected by their prior impressions. Moreover, following the second knowledge manipulation, children revised their story reports in ways that were consistent with their newly acquired impressions, which suggests that they had reconstructed their memories of previously heard stories. These findings provide evidence for both prospective and retrospective effects of knowledge on memory. 相似文献

7-month-old full-terms and high-risk preterms (less than 1,500 grams at birth) were compared on problems of visual recognition memory and tactual-to-visual cross-modal transfer. On the visual problems, preterm infants showed significantly less differential attentiveness to novelty than full-terms. They also required longer exposure times during visual familiarization, primarily because of longer pauses between fixations. Preterms and full-terms exhibited different patterns of looking, as indicated by the duration of fixation and the frequency in shifts of gaze. On the cross-modal problems, preterms and full-terms both exhibited similar and significant preferences for familiar rather than novel stimuli, a direction of preference which suggests that these problems were relatively difficult for both groups. For the preterms, novelty and exposure-time scores were found to be related to several medical risk factors. Novelty preferences were compromised in preterms who had suffered RDS postnatally, particularly those who had required prolonged mechanical ventilation. In general, high-risk preterms exhibited deficits in visual recognition memory and in the ability to recruit, sustain, and shift attention. 相似文献
