Effect of foster care on young children's language learning

This report examines 174 young children's language outcomes in the Bucharest Early Intervention Project, the first randomized trial of foster placement after institutional care. Age of foster placement was highly correlated with language outcomes. Placement by 15 months led to similar expressive and receptive language test scores as typical age peers at 30 and 42 months. Placement from 15 to 24 months also led to dramatic language improvement. In contrast, children placed after 24 months had the same severe language delays as children in institutional care. Language samples at 42 months confirmed that placement after 24 months led to lower expressive skill.  相似文献   

Problem-based learning and argumentation: testing a scaffolding framework to support middle school students’ creation of evidence-based arguments     

Brian R. Belland  Krista D. Glazewski  Jennifer C. Richardson 《Instructional Science》2011,39(5):667-694

Students engaged in problem-based learning (PBL) units solve ill-structured problems in small groups, and then present arguments in support of their solution. However, middle school students often struggle developing evidence-based arguments (Krajcik et al., J Learn Sci 7:313–350, 1998). Using a mixed method design, the researchers examined the use of computer-based argumentation scaffolds, called the Connection Log, to help middle school students build evidence-based arguments. Specifically we investigated (a) the impact of computer-based argumentation scaffolds on middle school students’ construction of evidence-based arguments during a PBL unit, and (b) scaffold use among members of two small groups purposefully chosen for case studies. Data sources included a test of argument evaluation ability, persuasive presentation rating scores, informal observations, videotaped class sessions, and retrospective interviews. Findings included a significant simple main effect on argument evaluation ability among lower-achieving students, and use of the scaffolds by the small groups to communicate and keep organized.  相似文献

Harnessing technology to improve formative assessment of student conceptions in STEM: forging a national network   总被引：2，自引：0，他引：2

Concept inventories, consisting of multiple-choice questions designed around common student misconceptions, are designed to reveal student thinking. However, students often have complex, heterogeneous ideas about scientific concepts. Constructed-response assessments, in which students must create their own answer, may better reveal students' thinking, but are time- and resource-intensive to evaluate. This report describes the initial meeting of a National Science Foundation-funded cross-institutional collaboration of interdisciplinary science, technology, engineering, and mathematics (STEM) education researchers interested in exploring the use of automated text analysis to evaluate constructed-response assessments. Participants at the meeting shared existing work on lexical analysis and concept inventories, participated in technology demonstrations and workshops, and discussed research goals. We are seeking interested collaborators to join our research community.  相似文献   

Home IV Antibiotic Therapy and Exercise Capacity in Children with CF: A Case Series     

Narelle S. Cox  Karen O. McKay  Jennifer M. Follett  Jennifer A. Alison 《Cardiopulmonary Physical Therapy Journal》2011,22(1):16-19

Purpose: This case series describes the effect of home intravenous (IV) antibiotic therapy on spirometry and exercise capacity in a group of children with cystic fibrosis (CF). Methods: Outcomes from 10 children with CF who were prescribed a 14-day course of home IV antibiotics for a respiratory exacerbation are reported. All children performed spirometry and a modified shuttle test (MST) before and after 14-days of home IV therapy. Results: After 14 days, FEV₁ increased by mean (± SE) 12 ± 4 % (p < 0.05) but mean MST did not improve compared to baseline. All children improved or maintained spirometry values with treatment, however, only 5 improved MST distance. Conclusion: After 14 days of home IV antibiotic therapy, a significant improvement in spirometry, but not exercise capacity, was seen in this small series of children with CF. The lack of improvement in exercise capacity for all children following home IV antibiotic therapy suggests factors other than spirometry determine exercise capacity. Identifying and investigating the factors that influence exercise capacity during home IV antibiotic therapy requires further investigation.Key Words: cystic fibrosis, home IV therapy, FEV₁, Modified Shuttle Test  相似文献   

e-Government stakeholders—Who are they and what do they want?     

Jennifer Rowley^{Author Vitae} 《International Journal of Information Management》2011,31(1):53-62

There is an increasing recognition that various stakeholder groups for e-government have a significant role to play in ensuring the long-term success of the e-government enterprise. This article seeks to contribute to the understanding of the stakeholders’ multiple perspectives by proposing typologies of stakeholder roles, and stakeholder benefits, respectively, and embedding these in a stakeholder benefits analysis tool. A literature review is used to surface the diverse existing categorizations of e-government stakeholders and their interests and the benefits sought. This review informs a proposal for a typology of stakeholder roles, and for a typology of stakeholder benefits, which together are used to construct an initial proposal for a stakeholder benefits analysis tool (SBAT), which can be used to map stakeholder roles to stakeholder benefits. This tool has been tested by an expert group, and revised. This exploratory study is an important first step towards the development of tools and approaches for understanding the benefits sought by a wide range of different stakeholder groups in e-government. Progress in the development of such tools is important for the development of knowledge and practice, policy, and evaluation with respect to stakeholder engagement with, and participation in, e-government.  相似文献

Can self-esteem protect against the deleterious consequences of self-objectification for mood and body satisfaction in physically active female university students?     

Thøgersen-Ntoumani C  Ntoumanis N  Cumming J  Bartholomew KJ  Pearce G 《运动与训练心理学杂志》2011,33(2):289-307

Using objectification theory (Fredrickson & Roberts, 1997), this study tested the interaction between self-objectification, appearance evaluation, and self-esteem in predicting body satisfaction and mood states. Participants (N = 93) were physically active female university students. State self-objectification was manipulated by participants wearing tight revealing exercise attire (experimental condition) or baggy exercise clothes (control condition). Significant interactions emerged predicting depression, anger, fatness, and satisfaction with body shape and size. For participants in the self-objectification condition who had low (as opposed to high) appearance evaluation, low self-esteem was associated with high depression, anger, and fatness and low satisfaction with body shape and size. In contrast, for participants with high self-esteem, these mood and body satisfaction states were more favorable irrespective of their levels of appearance evaluation. For female exercisers, self-esteem-enhancing strategies may protect against some of the negative outcomes of self-objectification.  相似文献
