Alternative models of the structure of individual and developmental differences of written composition and handwriting fluency
were tested using confirmatory factor analysis of writing samples provided by first- and fourth-grade students. For both groups,
a five-factor model provided the best fit to the data. Four of the factors represented aspects of written composition: macro-organization
(use of top sentence and number and ordering of ideas), productivity (number and diversity of words used), complexity (mean
length of T-unit and syntactic density), and spelling and punctuation. The fifth factor represented handwriting fluency. Handwriting
fluency was correlated with written composition factors at both grades. The magnitude of developmental differences between
first grade and fourth grade expressed as effect sizes varied for variables representing the five constructs: large effect
sizes were found for productivity and handwriting fluency variables; moderate effect sizes were found for complexity and macro-organization
variables; and minimal effect sizes were found for spelling and punctuation variables. 相似文献

Effects of child and environmental factors in moderating the course of bilingual development were investigated using longitudinal data, from age 2.5 to 5 years, on 126 U.S.-born children with early exposure to Spanish and English. Multilevel models of Spanish and English expressive vocabulary identified children’s phonological memory ability as a significant predictor of both outcomes, while also replicating the effect of the relative amount of language exposure. In addition, nonverbal IQ was a significant predictor of English vocabulary; birth order and maternal education in Spanish were significant predictors of Spanish vocabulary. These findings expand our understanding of the sources of the wide heterogeneity in bilingual development and of the requirements that language acquisition makes of learners and their environments. 相似文献

Many students at minority-serving institutions are underexposed to Internet resources such as the human genome project, PubMed, NCBI databases, and other Web-based technologies because of a lack of financial resources. To change this, we designed and implemented a new bioinformatics component to supplement the undergraduate Genetics course at Clark Atlanta University. The outcomes of the Bioinformatics course were assessed. During the first week of the semester, students were assigned the Felder-Soloman's Index of Learning Styles Inventory. The overwhelming majority of students were visual (82.1%) and sequential (75.0%) learners. Furthermore, pre- and postcourse surveys were administered during the first and the last week of the course to assess learning, confidence level, and mental activity. These indicated students increased the number of hours spent using computers and doing homework. Students reported confidence in using computers to study genetics increased, enabling them to better visualize and understand genetics. Furthermore, students were more mentally engaged in a more social learning environment. Although the students appreciated the value of the bioinformatics component, they reported the additional work load was substantial enough to receive additional course credit. 相似文献
