The Parent-Caregiver Relationship Scale (PCRS) was developed and field tested as a measure of the perceived quality of the relationship between the parent and the child care provider (“caregiver”) of an infant or toddler. PCRS items were based on review of the parent-caregiver relations literature and interviews with parents and caregivers. The parent and caregiver forms of the scale were administered to 217 parents and caregivers in child care centers and family child care homes. Analysis of the scale and its psychometric properties resulted in potentially useful subscales with adequate reliability. The PCRS showed predicted correlations with other child care context variables, providing preliminary support for its validity. The PCRS shows promise as a relationship-level measure for studies of infants, parents, and caregivers in the context of full-time child care. 相似文献

The purpose of this study was to empirically investigate, in a large-scale assessment, the prevalence of enquiry-based teaching, as defined by PISA, implemented in science lessons, and the extent to which it is related to students from different socioeconomic status (SES) family backgrounds in the U.S. The Programme of International Student Assessment (PISA) 2015 data including 5,146 students in the U.S. were used. A Latent Profile Analysis (LPA) was conducted to classify students into different science teaching subgroups. Mixture regression analysis was conducted to examine whether there the association between SES and achievement varied across science teaching subgroups. Four science teaching subgroups were identified, varying in the frequency of and type of teaching practices used. Students’ attitudes, gender, science instruction time, and reading achievement are significant predictors of the subgroup membership. SES-achievement gap also varied across the science teaching subgroups. Discussions for the results and suggestions for future study were presented. 相似文献

The adverse effect of increasing age and/or body weight on distance run performance has been well documented. Accordingly, nearly all five kilometer (5K) road races employ age categories and, sometimes, a heavier body weight classification. Problems with such conventions include small numbers of runners within older age categories and the advantage given to the lightest runners within each weight category. We developed a 5K Handicap (5KH), a model that calculates an adjusted run time based on the inputs of actual 5K run time, age, and body weight for men and women. This adjusted time, then, can be compared between runners of different ages and body weights. The purpose of this paper was to explain, in detail, the derivation of the 5KH formula using published theoretical and empirical findings on age, body weight and distance run time relationships. To our knowledge, the 5KH is the first such model and overcomes the problems associated with being heavier within one weight class and having too few runners in certain age categories. We are currently undertaking large-scale validation studies and evaluation of its race day implementation. 相似文献

This study was designed to assess the impacts of maltreatment reporting policies and reporting system structures on four aspects of entry into the child protection system (the maltreatment referral rate, the percentage of referrals screened in for investigation, the screened-in report rate and the substantiated report rate). Using secondary data from several sources, eight multiple linear regression models were created and analyzed. Results from a sample of 44 states indicated significant effects for system structure but no effects for reporting policies. Specifically, states with decentralized reporting system structures were significantly more restrictive in access than other states. These results have implications for child welfare administrators and policymakers seeking to maximize access for maltreated children and their families. 相似文献

Although instructional explanations are commonly used to introduce learners to new learning content, previous studies have often shown that their effects on learning outcomes are minimal. This failure might partly be due to mental passivity of the learners while processing introductory explanations and to a lack of opportunity to revise potential misunderstandings after working on introductory explanations. Against this background, we provided learners with two instructional support measures to optimise the introduction of new principles and concepts by providing instructional explanations in the domain of management theory: (a) prompts designed to induce inferences that are focused on the central content of the explanations, and (b) remedial explanations that are adapted to the learners’ knowledge gaps. We tested their effects in a 2 × 2 factorial experimental design with the following factors: (a) prompts designed to induce focused processing (with vs. without), and (b) remedial explanations (adapted vs. random). The participants consisted of 80 psychology students. We found that the prompts fostered both the share of deep-oriented processing and the acquisition of conceptual knowledge. The beneficial effect of prompts on conceptual knowledge was mediated by the number of inferences that learners generated in response to the prompts. In addition, we found that prompts also fostered the instructional efficiency of providing instructional explanations. The provision of adapted remedial explanations, however, fostered neither deep-oriented processing nor the acquisition of conceptual knowledge. We conclude that prompts designed to induce focused processing can foster deep-oriented processing as well as both the effectiveness and efficiency of learning from instructional explanations. 相似文献

A historical review of visualization in human cognition 总被引:1,自引:0,他引:1
This paper presents a historical overview of visualization as a cognitive strategy in human creativity, discovery, and problem-solving.
Visualization strategies, such as mental imagery, pervade historical accounts of scientific discovery and invention. A selected
number of historical examples are presented and discussed on topics such as physics, aviation, and the science of chaos. Everyday
examples are also discussed to show the value of visualization in cognition for all people. Several counter examples are also
discussed showing that visualization can also lead to erroneous conclusions. Many educational implications are discussed,
such as reconsidering the dominant role and value schools place on verbal, abstract thinking. These issues are also considered
in light of emerging computer-based technologies, such as virtual reality. 相似文献

The opinions of 108 teachers, about what influenced adolescent students' motivation and de-motivation, were sought through interview, at sites in each of the UK, the USA and Russia. Teachers' opinions in all three milieux were found to concur—on the positive effects of: parental interest and involvement and parental dissatisfaction; partnership with parents; teacher-student relations; symbolic and material rewards; grades and marks; success in learning—and on the negative effects of some leisure pursuits and of potential post-school unemployment. However, the meaning to be attached to such concurrence is problematised by contextualising apparent agreement within significantly differing local arrangements for, and expectations of: partnership with parents; continuity and duration of teacher-student-parent relations; the development of teachers' professional learning from experience; the deployment of praise and criticism; the pedagogical use of assessment; and the deployment of out-of-school time. Amplifying effects of peer and community subcultures, on the influence of potential unemployment, were also found to differ between contexts. It is concluded that whilst points of concurrence in teachers' opinions are of undoubted interest for any general theory of motivation to learn in school, methods which explore the conceptual system and semantic structure of the background beliefs which inform the expressed opinions that respondents express are urgently needed. The paper argues that we need to be able to model the underlying expectations and constraints which lend structure and priority to the lived experience of being schooled. 相似文献
