While the critical importance of phonological awareness (segmental phonology) to reading ability is well established, the potential role of prosody (suprasegmental phonology) in reading development has only recently been explored. This study examined the relationship between children's prosodic skills and reading ability. Hierarchical multiple regression analyses examined the unique contribution of word‐level and phrase‐level prosodic skills to the prediction of three concurrent measures of reading ability in 81 fourth‐grade children (mean age 9.3 years). After controlling for phonological awareness and general rhythmic sensitivity, children's prosodic skills predicted unique variation in word‐reading accuracy and in reading comprehension. Phrase‐level prosodic skills, assessed by means of a reiterative speech task, predicted unique variance in reading comprehension, after controlling for word reading accuracy, phonological awareness and general rhythmic sensitivity. These results add to the growing body of evidence of the importance of prosodic skills in reading development.  相似文献

The aim of the study is to investigate the measurement invariance of mathematics self-concept and self-efficacy across 40 countries that participated in the Programme for International Student Assessment (PISA) 2003 and 2012 cycles. The sample of the study consists of 271,760 students in PISA 2003 and 333,804 students in PISA 2012. Firstly, the traditional measurement invariance testing was applied in the multiple-group confirmatory factor analysis (MGCFA). Then, the alignment analyses were performed, allowing non-invariance to a minimum to estimate all of the parameters. Results from MGCFA indicate that mathematics self-concept and self-efficacy hold metric invariance across the 80 groups (cycle by country). The alignment method results suggest that a large proportion of non-invariance exists in both mathematics self-concept and self-efficacy factors, and the factor means cannot be compared across all participating countries. Results of the Monte Carlo simulation show that the alignment results are trustworthy. Implications and limitations are discussed, and some recommendations for future research are proposed.

This study investigated differences in student perceptions and performance among three distance learning sites taking the same off-campus M.B.A. course with the same instructor, The sites varied in class size and instructor location. Two classes (one large and one small) were linked using a two-way video system with rotating origination. The third class was small and was taught in person each week. Data were collected over an entire semester. Class size influenced performance more than location of instructor. Performance in the two smaller classes was better than performance in the large class. Student characteristics and site variables accounted for over 50% of variance in performance. One interaction effect was found. Students with initial low perceived value did best when the instructor was physically present each week. For students with high initial perceived value, location of instructor did not matter.  相似文献
