This study examined the underlying structure of the Nonverbal Literacy Assessment (NVLA), an instrument designed to measure emergent literacy for K–fourth‐grade students with severe developmental disabilities. The NVLA was conceptualized as having six constructs that reflected emergent literacy skills: (a) phonemic awareness, (b) phonics, (c) comprehension, (d) vocabulary, (e) listening comprehension, and (f) text awareness. Confirmatory factor analysis using data from 207 student administrations was used to examine the six‐factor model and two alternative models. Results suggested that all three models fit the data, but the high corrections coefficients among the constructs suggested that a one‐factor model of emergent literacy was the best‐fitting model. Implications and limitations are discussed. © 2010 Wiley Periodicals, Inc. 相似文献

A case study examined the collaborative experiences of students in an online business writing classroom. The purpose was to examine the same groups of students working on collaborative writing assignments in both a synchronous (real-time) and an asynchronous (non-real-time) discussion forum. This study focused on examining the amount, pattern, and focus of interactions, as well as assessing students' attitudes toward communicating in the two different environments. 相似文献
