The impact of Web 3.0, also known as the Semantic Web, on online learning is yet to be determined as the Semantic Web and
its technologies continue to develop. Online instructors must have a rudimentary understanding of Web 3.0 to prepare for the
next phase of online learning. This paper provides an understandable definition of the Semantic Web and its terminology, and
then explores possible implications of Web 3.0 on online learning. The foundation of the Semantic Web is data integration.
By using metadata, “display only” data is converted to meaningful information which can be located, evaluated, and delivered
by software agents. Web 3.0 technologies will assist online instructors in the areas of course development, learner support,
assessment, and record keeping. Online students will benefit from learning personalization and knowledge construction powered
by the Semantic Web. 相似文献

Limited evidence supports the external validity of the distinction between developmental phonological and surface dyslexia. We previously identified children ages 8 to 13 meeting criteria for these subtypes (Peterson, Pennington, & Olson, 2013) and now report on their reading and related skills approximately 5 years later. Longitudinal stability of subtype membership was fair and appeared stronger for phonological than surface dyslexia. Phonological dyslexia was associated with a pronounced phonological awareness deficit, but subgroups otherwise had similar cognitive profiles. Subtype did not inform prognosis. Results provide modest evidence for the validity of the distinction, although not for its clinical utility. 相似文献

This study examined the relative contributions of phonological awareness, orthographic pattern recognition, and rapid letter
naming to fluent word and connected-text reading within a dyslexic sample of 123 children in second and third grades. Participants
were assessed on a variety of fluency measures and reading subskills. Correlations and hierarchical multiple regression analyses
were carried out to explore these relationships. The results demonstrate that phonological awareness, rapid letter naming,
and orthographic pattern recognition contribute to word-reading skills. Furthermore, rapid naming, orthographic pattern recognition,
and word reading fluency moderately predict different dimensions of connected-text reading (i.e., rate, accuracy, and comprehension)
whereas phonological awareness contributes only to the comprehension dimension of connected-text reading. The findings support
the multidimensional nature of fluency in which the whole is more than its parts. 相似文献

We used a comparative interrupted time series design to examine the impact of the Massachusetts' Wraparound Zone Initiative on student achievement, attendance, retention, and suspension. This initiative was designed to create coordinated district systems that allow schools to proactively and systematically address students' nonacademic needs. The state education agency awarded grants to seven high-need districts, each of which used the funds to support a select group of schools in implementing strategies that focused on school climate and culture, family engagement, systems to identify and address student needs, and community partnerships. Results from this study showed that students in Wraparound Zone schools performed better on state academic assessments than students in comparison schools, when considering prior achievement trends. Effects were statistically significant in the 3rd year of implementation. The impact on academic achievement was greatest for third- and fourth-grade students, and was particularly strong for English learners. There was no statistically significant overall impact on attendance, retention, or suspension. 相似文献
