A sample of 170 Italian children was assessed for reading accuracy, reading speed, text comprehension and spelling in Grades 1 and 3 in order to investigate the concurrent and longitudinal relationships among literacy skills. Main results from multivariate analyses (regression, discriminant and path analyses) indicated that reading speed was the best predictor of later literacy and that spelling was the most stable measure and influenced text comprehension and reading speed. An asymmetry was also observed in the longitudinal relationship between reading and spelling errors, with reading errors predicting later spelling errors and a non-significant result in the opposite direction.  相似文献

In this paper the problem of indexing heterogeneous structured documents and of retrieving semi-structured documents is considered. We propose a flexible paradigm for both indexing such documents and formulating user queries specifying soft constraints on both documents structure and content. At the indexing level we propose a model that achieves flexibility by constructing personalised document representations based on users views of the documents. This is obtained by allowing users to specify their preferences on the documents sections that they estimate to bear the most interesting information, as well as to linguistically quantify the number of sections which determine the global potential interest of the documents. At the query language level, a flexible query language for expressing soft selection conditions on both the documents structure and content is proposed.  相似文献

This paper reports an intensive study of problem-solving activity of female students at the senior secondary level. The study focussed both on the mathematical processing and the underlying cognitive and metacognitive activities that led to that processing. Response maps were used to analyse and categorize the written responses from individual students while videotaped problem solving sessions and structured and free response interviews probed the students' metacognitive knowledge, strategies, decision making, beliefs and affects. Metacognitive activities were involved in all phases of the solution process with key points in students' solutions identifiable in terms of the cognitive-metacognitive framework of Garofalo and Lester (1985). On average more time was spent on orientation and execution activities with little time being spent on organisation and verification activities, however, the successful groups spent less time on orientation than the other groups. All successful groups displayed a high number of key points where metacognitive decisions could influence cognitive action. Success was accompanied by a tendency to engage in a high number of organisational activities, regulation of execution activities and evaluation activities particularly evaluation of execution but fewer opportunities where metacognitive decisions could influence cognitive actions during orientation.  相似文献

Although short-term mobility programmes are increasingly promoted to university students as sources of competitive advantage, there is little research on academic learnings arising from these initiatives. A ‘field analysis’ of outbound mobility is undertaken to identify convergences and disjunctures between institutional discourses, staff perceptions and student experiences at one Australian university where outbound mobility is actively promoted as a ‘strategy of distinction’. Self-reported ‘personal transformations’ commonly associated with the mobility experience are interrogated in favour of alternative constructions of self–other relationships. An argument is made for greater institutional effort to enable students to make critical connections with ‘other-ness’ both in and out of place.  相似文献

The purpose of this study was to examine whether using a multiple‐measure framework yielded better classification accuracy than oral reading fluency (ORF) or maze alone in predicting pass/fail rates for middle‐school students on a large‐scale reading assessment. Participants were 178 students in Grades 7 and 8 from a Midwestern school district. The multiple‐measure framework yielded classification accuracy rates that were either similar to, or better than, the individual predictors. Specificity was improved using a combined measure of ORF and maze versus individual predictors alone. Educational implications for identifying students in need of reading intervention are discussed.  相似文献

The current study was designed to understand the development of comprehension monitoring among beginner readers from first to third grade, and to determine the extent to which first graders’ comprehension monitoring predicts reading comprehension in grade three. Participants were 113 children (57% female) from four US states who were followed from Grade 1 (M = 7 years, SD = 4 months) to Grade 3 (M = 9 years, SD = 4 months). Measures included decoding, vocabulary, working memory, comprehension monitoring, and reading comprehension. Children’s ability to monitor comprehension grew significantly from first to third grade, with a deceleration in growth over time. In addition, comprehension monitoring in Grade 1 made a significant contribution to reading comprehension in Grade 3, even after controlling for decoding, vocabulary, and working memory. Together, these findings supplement our understanding of young readers’ development of comprehension monitoring as well as its association with reading comprehension at a later time. Practical implications of the results in the context of providing support for higher-level language skills in beginning reading instruction are discussed.  相似文献
