Selected AbstractsA Tiered Intervention Model for Early Vocabulary Instruction: The Effects of Tiered Instruction for Young Students At Risk for Reading DisabilityLEARNING DISABILITIES RESEARCH & PRACTICE, Issue 3 2010Paige C. Pullen Vocabulary knowledge at school entry is a robust predictor of later reading achievement. Many children begin formal reading instruction at a significant disadvantage due to low levels of vocabulary. Until recently, relatively few research studies examined the efficacy of vocabulary interventions for children in the early primary grades (e.g., before fourth grade), and even fewer addressed vocabulary intervention for students at increased risk for reading failure. In more recent work, researchers have begun to explore ways in which to diminish the "meaningful differences" in language achievement noted among children as they enter formal schooling. This article provides a review of a particularly effective model of vocabulary intervention based on shared storybook reading and situates this model in a context of tiered intervention, an emerging model of instructional design in the field of special education. In addition, we describe a quasi-experimental posttest-only study that examines the feasibility and effectiveness of the model for first-grade students. Participants were 224 first-grade students of whom 98 were identified as at risk for reading disability based on low levels of vocabulary. Results of a multivariate analysis of variance revealed significant differences on measures of target vocabulary knowledge at the receptive and context level, suggesting that students at risk for reading failure benefit significantly from a second tier of vocabulary instruction. Implications for classroom practice as well as future research are provided. [source] On-line automatic SPE-CE coupling for the determination of biological markers in urineELECTROPHORESIS, Issue 5 2007José Ruiz-Jiménez Abstract Automatic SPE has been coupled on-line to CE by a transfer tube and the replenishment system of the CE instrument. The approach allows the target analytes (viz. creatinine, creatine, xanthine, hypoxanthine, uric acid, p -aminohippuric acid and ascorbic acid in urine samples) to be removed from the sample matrix, cleaned up, preconcentrated and injected into the capillary. The detection limits range between 0.14 and 4.50,,g/mL, the quantification limits between 0.45 and 15.0,,g/mL, and linear dynamic ranges , which include the reference healthy human values , from the quantification limits to 1332,,g/mL. The precision, expressed as RSD, ranges between 0.38 and 2.22% for repeatability and between 1.79 and 7.61% for within-laboratory reproducibility. The errors, expressed as RSD for all compounds, range between 0.20 and 6.90%. The time for automatic SPE and that necessary for the individual separation,detection of the target analytes are 13 and 12,min, respectively; the analysis frequency is 5,h,1. The accuracy of the method and potential matrix effects were studied by using spiked samples and recoveries between 96.00 and 103.07 % were obtained. The proposed method was applied to samples from healthy young students. [source] Body image treatment for a community sample of obligatory and nonobligatory exercisersINTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 4 2001Jane Ellen Smith Abstract Objective Cognitive-behavioral therapy (CBT) was used to treat body dissatisfaction in obligatory and nonobligatory exercisers within a community sample of normal weight women. Method Ninety-four women (36% obligatory exercisers, 64% nonobligatory exercisers) were assigned randomly to CBT or the waiting-list (WL) control group. Results The hypotheses that obligatory exercisers would show poorer pretreatment body image and greater compulsivity than nonobligatory exercisers were supported partially. The prediction that obligatory exercisers would respond less favorably to treatment was not supported. Overall, CBT participants evidenced significantly better body image outcomes than the WL at posttreatment, but many effects were lost by the follow-up. Discussion Treatment response is considered in light of the unique characteristics of this ethnically diverse, older community sample when compared with the young students in earlier body image intervention studies. The high rate of physical activity among even the nonobligatory exercisers is highlighted for its mood-regulation properties and its treatment implications. © 2001 by John Wiley & Sons, Inc.

[source] Korean 4- to 11-year-old student conceptions of heat and temperatureJOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 2 2007Seoung-Hey Paik The aim of the present study is to shed light on the conceptions that young students have of heat and temperature, concepts that are both important in school science curricula and closely related to daily life. The subjects of the study were students from a rural district in South Korea and they ranged in age from 4 to 11 years. Interviews were conducted with each student on the basis of questions on temperature, thermal insulation, and heat equilibrium. After calculating the frequency and percentage of student responses and analyzing the rationale for their answers, it was found that younger students tended to view temperature as "size" or a "summation of numbers." This tendency gradually diminished in older students. Most students had alternative conceptions of thermal insulation regardless of age; however, reasoning differed according to age. Younger students displayed a greater tendency to view insulation as a material property, whereas older students showed a greater tendency toward rational heat and temperature conceptions. Most students did not have clear concepts of heat equilibrium regardless of age, but possessed numerous alternative conceptions. © 2007 Wiley Periodicals, Inc.

MATTHEWSMETAPHILOSOPHY, Issue 1 2008SARA GOERING Abstract: This article highlights Gareth Matthews's contributions to the field of philosophy for young children, noting especially the inventiveness of his style of engagement with children and his confidence in children's ability to analyze perplexing issues, from cosmology to death and dying. I relate here my experiences in introducing philosophical topics to adolescents, to show how Matthews's work can be successfully extended to older students, and I recommend taking philosophy outside the university as a way to foster critical thinking in young students and to improve the public status of the profession. [source] Effect of daytime light conditions on sleep habits and morningness,eveningness preference of Japanese students aged 12,15 yearsPSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 3 2002TETSUO HARADA phd Abstract The effect of daytime light conditions on the sleep habits and morning,evening preference of Japanese junior high school students (415 girls and 411 boys; age range, 12,15 years old) was studied. Students who were outdoors during the short break between classes or their lunch-time break were more morning-type people than those who remained indoors. Students who shut out the light from outside showed longer subjective sleep latency and appealed more shallow sleep rather than those who did not. Sunlight can be an important factor for the timing of sleep based on the circadian system of Japanese young students. [source] Understanding heterologous protein overproduction under the T7 promoter: A practical exerciseBIOCHEMISTRY AND MOLECULAR BIOLOGY EDUCATION, Issue 3 2002Evangelos Christodoulou Abstract Because various genome projects have been advanced many genes are known, and large amounts of proteins are required to elucidate their function. Most biomolecular research laboratories have a need to overexpress a certain gene, or a part of it, in eukaryotic or prokaryotic expression systems. It is therefore important for young students to become familiar with the technology of heterologous gene expression systems. Gene expression in eukaryotic cells is rather complicated and costly and is therefore not ideally suited to exercises for students. The goal of this paper is to describe an experimental example of a well known and broadly used prokaryotic system, the pET system, that works under the strong T7 promoter. The clones described in this paper are suitable for the practical exercise and are available upon request. [source] | |||||||||||||
