The purpose of this study was to examine African American children’s performance on a phonological awareness task that included items reflecting differences between African American English (AAE) and mainstream American English. The relationship between spoken production of AAE forms and performance on phonological awareness, vocabulary, and letter-word recognition tasks was also investigated. Analyses indicated that children who produced fewer AAE features in speech performed significantly different from those who produced AAE features more frequently on the experimental phonological awareness task. Furthermore, analyses showed that the relationship between spoken AAE production and phonological awareness was partially mediated, while the relationship with letter-word recognition was fully mediated. Overall, the results suggest a direct relation between spoken AAE use and phonological awareness and an indirect relation with letter-word reading.  相似文献

Achievement in mathematics of eighth-grade students is modeled as a function of within-school, between-school and cross-country differences. The data were obtained from 217,728 students, within 7,216 secondary schools, in 48 countries, who participated in the 2007 Trends in International Mathematics and Science Study. Multilevel analysis showed that out of the total variance in mathematics achievement, 40.39%, 20.61%, and 38.99% were accounted for within-school, between-school-within-country, and cross-country differences, respectively. Mathematics self-concept followed by socioeconomic status was the strongest predictor of achievement at the student level. At the school level, school location yielded the strongest link to achievement, while at the country level socioeconomic status was the main predictor of national mathematics average.  相似文献
