Through semi‐structured interviews, this study explored 11 bilingual school psychologists’ (BSPs) consultation experiences with teachers of English learners (EL) to determine referral concerns, recommendations made, challenges encountered, preparation experiences, and skills most needed. The most common referral issue concerned students’ academic performance and teachers’ attempts to parse out language acquisition difficulties from learning problems. Principal consultation challenges included the scarcity of trained professionals, teacher bias, and the stress of competing school priorities. BSPs relied most on their interpersonal skills and relationship building skills, as well as their knowledge of EL‐focused interventions and their problem identification skills. Recommendations to their monolingual school psychology colleagues included the need to actively seek out a) language and culture resources, b) relevant professional development opportunities, and c) consultations with fellow BSPs. Study limitations and implications are discussed.  相似文献

Background: A body of literature has emerged that links inattentive symptoms of attention deficit hyperactivity disorder (ADHD) to poor academic achievement. Major variation across studies renders conclusions about this relationship complex.

Purpose: This review will provide a qualitative synthesis of these studies that (1) use community samples and (2) examine inattention as a separate dimension from hyperactivity/impulsivity. The aim of this review is to ascertain whether the relationship documented between inattention and academic outcomes in ADHD also holds for the dimensional trait of inattention as manifest in non-clinical community samples of children and adolescents, taking into consideration both academic achievement and academic performance across age.

Design and methods: A comprehensive search was carried out using two databases. The PRISMA guidelines were used to report the search steps. The QUIPS tool was used to rate the quality of studies, followed by a best evidence synthesis to summarise these results.

Results: Out of 1748 citations found, 27 articles met the specific inclusion criteria. Results point to a strong effect according to the best evidence synthesis: 7 studies that have low risk of bias found that teacher-rated inattention is significantly predicative of poor academic achievement in community samples of children.

Conclusions: This review provides support for a consistent, negative relationship between classroom inattention as reported by teachers and both standardised academic test achievement and classroom performance outcomes for children in preschool (moderate evidence), elementary school and longitudinally from elementary to high school. The average relationship was stronger when classroom performance was measured, as compared to standardised achievement. However, the quantitative strength of relationship has not been confirmed with a meta-analysis due to heterogeneity and too few high-quality studies identified. Variance across the studies in terms of the strength of association suggests that other unexamined factors (e.g. cognitive function or motivation) may be contributing to this relationship. Implications for educators and clinicians who work within the school setting are discussed.  相似文献

This study sought to discover some of the causes of initial interset in and atrition from the natural sciences and engineering among the students (N=5320) who entered four highly selective institutions in 1988, with particular attention to possible special causes for the disproportionate attrition of women from science. Though a smaller proportion of women (35 percent) than men (49 percent) were initially interested in science, gender added little to the prediction of such initial choice when preadmission measures of developed abilities were taken into account in regression analysis. Of the group of 2,276 students initially interested in science, 40 percent did not finally concentrate in science, and smaller proportions of women (48 percent) than of men (66 percent) persisted. The most significant cognitive, factor predicting these losses was low grades earned in science courses taken during the first two years of study. With grades held equal, gender was not a significant predictor of persistence in engineering and biology; gender added strongly to grades, however, as a factor associated with unusually large losses of women from a category that included the physical sciences and mathematics. Responses to a questionnaire administered in the fall of 1991 showed that science majors regarded their instruction as too competitive, with too few opportunities to ask questions, taught by professors who were relatively unresponsive, not dedicated, and not motivating. Students who defected from science did so largely because of the attraction of other fields, but many shared the criticism of overcompetitiveness and inferior instruction, along with the view that the work was too difficult. Several items were about elements of classroom instruction and atmosphere thought to be especially difficult for women (i.e., the chilly climate), but except for perceived competitiveness, women did not rate their classroom experiences as being more unpleasant than did men. This research was supported by grants from the Alfred P. Sloan Foundation and the National Science Foundation.  相似文献

Using survey and interview data from the Teacher Status Project, this paper explores early years teachers' sense of status and compares it with primary and secondary teachers' perceived status. If, as Hoyle has suggested, working with children is an intractable barrier to enhanced status in the eyes of the public, early years teachers are faced with the greatest challenge. At the same time, their closer links with parents and community affords them more opportunity to enhance the esteem in which they are held through the way that they do their work. The data seem to support this view, but it is argued that whilst curriculum guidance, and the recognition of the Foundation Stage have enhanced these teachers' sense of status in the public eye, the effects of the ten‐year strategy could undermine this progress unless an emphasis is placed on the teaching, pedagogical element of their specialist expertise.  相似文献

PURPOSE: Chest radiographs (CXR) are the standard method for evaluating rib fractures in abused infants. Computed tomography (CT) is a sensitive method to detect rib fractures. The purpose of this study was to compare CT and CXR in the evaluation of rib fractures in abused infants. METHODS: This retrospective study included all 12 abused infants identified from 1999 to 2004 who had rib fractures and both CXR and CT (8 abdomen CTs, 4 chest CTs). CT exams had been performed for clinical indications, and were obtained within one day of the CXR. Studies were reviewed by two pediatric radiologists to determine the number, locations, and approximate ages of the rib fractures. A total of 225 ribs were completely (192) or partially (33) seen by CT, and the matched ribs on CXR were used for the analysis. RESULTS: The mean patient age was 2.5 months (1.2-5.6), with seven females and five males. While 131 fractures were visualized by CT, only 79 were seen by CXR (p<.001). One patient had fractures only seen by CT. There were significantly (p<.05) more early subacute (24 vs. 4), subacute (47 vs. 26), and old fractures (4 vs. 0) seen by CT than by CXR. Anterior (42 vs. 11), anterolateral (21 vs. 12), posterolateral (9 vs. 3) and posterior (39 vs. 24) fractures were better seen by CT than by CXR (p<.01). Bilateral fractures were detected more often by CT (11) than by CXR (6). CONCLUSIONS: While this study group is small, these findings suggest that CT is better than CXR in visualizing rib fractures in abused infants.  相似文献

This study aimed to determine which types of context clues exist in children's texts and whether it is possible for experts to identify reliably those clues. Three experienced coders used Ames’ clue set as a foundation for a system to classify context clues in children's text. Findings showed that the adjustments to Ames’ system resulted in 15 clues that can be used to capture the majority of clues found in children narrative and expository text. This study adds to the limited empirically validated systems available for classifying different context clues. A usable classification of context clues has application to reading research that considers or controls for text factors as well as teaching reading strategies in K–12 classrooms.  相似文献

The prospect of European integration calls urgently for educational provision which will enable Europe's school‐leavers to understand and appraise the process. Essentially, this provision is historical. What is distinctive about Europe? What made us what we are? It is suggested that modem Europe is, at bottom, the result of two related things‐‐conflict and ideas‐‐and that the conflicts have arisen because of the ideas, and have constituted their final working‐out. Three ideas, with their related conflicts, seem fundamental, and these three pairings indicate the appropriate content for a history course for Europe's senior pupils. The three ‘ideas ‘ are the Reformation, the Enlightenment and Nationalism, and the related conflicts are the 30 Years’ War, the French Revolutionary and Napoleonic Wars and the World Wars of this century. The coverage of the first pairing is sketched as an example of how the whole course may be mounted and to introduce a master theme of European history for the last 300 years. The paper ends with a brief discussion of why other seemingly crucial factors are not selected and discussed.  相似文献
