Classroom behavior of children and adolescents with learning disabilities: a meta-analysis     

W N Bender  J K Smith 《Journal of learning disabilities》1990,23(5):298-305

Meta-analysis was used to review the results of 25 studies that compared the classroom behavior of children and adolescents with learning disabilities (LD) to children without learning disabilities. The data were analyzed from several different methodological perspectives. Results showed that both methodologically strong and weak studies demonstrated significant behavioral deficits of children with learning disabilities compared to their nondisabled peers in each of five overall areas: on-task behavior, off-task behavior, conduct disorders, distractibility, and shy/withdrawn behavior. Both observational and teacher rating data demonstrated these differences. Effect sizes for both groups of studies seemed to cluster around 1 standard deviation, suggesting noticeable and educationally significant impairment in the behavior of children with disabilities. Analysis of grade-level effect sizes suggests some explanation for the large number of referrals often witnessed during the elementary school years. Educational implications of these behavioral differences in terms of implications for mainstreaming are discussed.  相似文献   

Motor activity, anticipated motor activity, and young children's associative learning.     

B G Bender  J R Levin 《Child development》1976,47(2):560-562

The purpose of this study was to determine whether motor activity, previously assumed necessary to induce imagery in young children's associative learning, actually has to be executed. The results of our experiment with kindergartners clearly suggest not: In conditions where subjects simply planned to the potential motor activity (without executing it), learning was enhanced. Further, the temporal proximity of the planning to the potential motor activity did not prove to be important. These results, combined with those from 2 follow-up experiments, give rise to the speculation--among others--that young children can be "tricked" into imagery generation through appropriately worded instructions.  相似文献   

Teachers' education, classroom quality, and young children's academic skills: results from seven studies of preschool programs   总被引：10，自引：0，他引：10

In an effort to provide high-quality preschool education, policymakers are increasingly requiring public preschool teachers to have at least a Bachelor's degree, preferably in early childhood education. Seven major studies of early care and education were used to predict classroom quality and children's academic outcomes from the educational attainment and major of teachers of 4-year-olds. The findings indicate largely null or contradictory associations, indicating that policies focused solely on increasing teachers' education will not suffice for improving classroom quality or maximizing children's academic gains. Instead, raising the effectiveness of early childhood education likely will require a broad range of professional development activities and supports targeted toward teachers' interactions with children.  相似文献   

Das MINERVA-Projekt: Datenbankselektion für Peer-to-Peer-Websuche

Zusammenfassung In diesem Artikel wird MINERVA pr?sentiert, eine prototypische Implementierung einer verteilten Suchmaschine basierend auf einer Peer-to-Peer (P2P)-Architektur. MINERVA setzt auf die in der P2P-Welt verbreitete Technik verteilter Hash-Tabellen auf und benutzt diese zum Aufbau eines verteilten Verzeichnisses. Peers in unserem Ansatz entsprechen v?llig autonomen Benutzern mit ihren lokalen Suchm"oglichkeiten, die bereit sind, ihr lokales Wissen und ihre lokalen Suchm?glichkeiten im Rahmen einer Kollaboration zur Verfügung zu stellen. Wir formalisieren unsere Systemarchitektur und beschreiben das zentrale Problem einer effizienten Suche nach vielversprechenden Peers für eine konkrete Anfrage innerhalb des Verbundes. Wir greifen dabei auf existierende Methoden zurück and passen diese an unseren Systemkontext an. Wir pr?sentieren Experimente auf realen Daten, die verschiedene dieser Ans?tze vergleichen. Diese Experimente zeigen, dass die Qualit?t der Ans?tze variiert und untermauern damit die Wichtigkeit und den Einfluss einer leistungsstarken Methode zur Auswahl guter Datenbanken. Unsere Experimente deuten an, dass eine geringe Anzahl sorgf?ltig ausgew?hlter Datenbanken typischerweise bereits einen Gro?teil aller relevanten Ergebnisse des Gesamtsystems liefert.

This paper presents the MINERVA project that protoypes a distributed search engine based on P2P techniques. MINERVA is layered on top of a Chord-style overlay network and uses a powerful crawling, indexing, and search engine on every autonomous peer. We formalize our system model and identify the problem of efficiently selecting promising peers for a query as a pivotal issue. We revisit existing approaches to the database selection problem and adapt them to our system environment. Measurements are performed to compare different selection strategies using real-world data. The experiments show significant performance differences between the strategies and prove the importance of a judicious peer selection strategy. The experiments also present first evidence that a small number of carefully selected peers already provide the vast majority of all relevant results.

Do Fourteenth Amendment considerations outweigh a potential state interest in mandating cochlear implantation for deaf children?     

Bender DG 《Journal of deaf studies and deaf education》2004,9(1):104-111

Currently, the decision concerning pediatric cochlear implantation for children remains a personal choice for parents to make. Economic factors, educational outcomes, and societal attitudes concerning deafness could result in an increased governmental interest in this choice. This article examines case law related to the issue of parental autonomy to determine whether the state, acting in the role of parens patriae, could use economic and social reasons to mandate the provision of cochlear implants for all eligible children. The author uses previous cases as a framework to develop an opinion on whether a constitutional protection for parents may exist.  相似文献

Four-year follow-up study of language impaired children     

Rachel E. Stark  Lynne E. Bernstein  Rosemary Condino  Michael Bender  Paula Tallal  Hugh Catts 《Annals of dyslexia》1984,34(1):49-68

Children identified as normal or as specifically language impaired (SLI) were given speech, language, and intelligence testing on a longitudinal basis. Fourteen normal and 29 SLI children between the ages of 4 1/2 and 8 years were tested at Time 1. They were retested three to four years later when they were 8 to 12 years old. The results indicated that both the normal and the SLI children continued to develop skills in receptive and expressive language and speech articulation across the 3- to 4-year period intervening between evaluations. Overall, however, the SLI children appeared to develop language skills at a slower than normal rate and 80% of them remained language impaired at Time 2. In addition, the majority of the SLI children manifested reading impairment at Time 2, while none of the normal children did so. The implications for the educational management of SLI children are discussed. Research supported by the March of Dimes, Grant #12-84.

A comparison of sentence-learning errors in children of different achievement levels     

Joel R. Levin  Elizabeth S. Ghatala  Bruce G. Bender 《Contemporary educational psychology》1978,3(4):358-366

Theoretical analyses of the multiple-choice test format suggest that a test constructor should give serious consideration to the form in which correct and incorrect alternatives are presented. In this experiment, third and fourth graders were tested for previously exposed information by multiple-choice items in which: (a) correct alternatives were stated in either verbatim or synonym form; and (b) incorrect alternatives consisted of plausible responses that were either familiar or new. Comparisons of errors and error patterns were made between high and low achieving students who had been given one of two different information-processing strategies. Based on a dual test function argument, it was concluded that synonym correct alternatives combined with plausible new responses are the most desirable of the four multiple-choice variations studied here. In particular, such items were sensitive to achievement level and strategy differences without systematically increasing students' likelihood of retaining misinformation.  相似文献
