This meta-analysis synthesizes the last two decades of experimental and quasi-experimental research on reading instruction across academic contexts (e.g., social studies, science, mathematics, English language arts) for English learners (ELs) in grades 4 through 8, to determine (a) the overall effectiveness of reading instruction for upper elementary and middle school students who are ELs and (b) how the magnitude of the effect varies based on student, instructional, and study characteristics. The analysis included a total of 11 studies with 46 individual effect sizes and yielded a mean effect size of g?=?0.35 across all (i.e., standardized and unstandardized) reading measures, g?=?0.01 across standardized reading measures, and g?=?0.43 across unstandardized reading measures. For all reading, unstandardized reading, all vocabulary, and unstandardized vocabulary measures, results suggest that higher quality studies tended to have smaller effects, and these effects were even more evident for unstandardized measures (i.e., one unit increase in study quality was associated with decreased effects: g?=?0.21, g?=?0.30, g?=?0.24, g?=?0.30, respectively). For all comprehension measures, effects were larger for instruction that included both vocabulary and comprehension (g?=?0.39) than for instruction that focused on vocabulary alone (g?=?0.08). Results suggest the benefit of developing and refining high-impact approaches to reading instruction for ELs that can be delivered across content areas and grades.  相似文献

In Experiment 1, rats were trained to leverpress on a variable ratio (VR) 30 schedule with a 500-msec delay between the reinforced response and food delivery. Subjects that experienced a signal during the delay responded faster than did control subjects that received the stimulus un-correlated with reinforcement. Higher response rates were obtained when the stimulus used to signal reinforcement was auditory rather than visual. Experiments 2 and 3 compared the effects of signaling reinforcement with either a localized or a diffuse light on responding maintained by VR schedules of reinforcement. Elevated response rates were observed with the diffuse stimulus, but the localized stimulus failed to produce such potentiation. Experiment 3 also examined the conditioned reinforcing power of localized and diffuse visual stimuli. These results are discussed with reference to (1) theories of selective association and sign tracking and (2) their implications for current theories of signaling reinforcement.  相似文献

The research described in this article reports the results of a study designed to evaluate the relationship among object‐oriented (OO) computer programming task performance and a student's (1) theoretical value belief, (2) cognitive ability, and (3) personality. The results of this study do not support the assertion that cognitive ability is a main determinant of performance. Rather, the findings suggest that characteristics of an individual nature have more effect on a student's performance. This supports our belief advanced herein that theoretical value belief and personality are significant predictors of computer programming performance in OO environments. From the findings of this study, we assert that academicians who must teach OO computer programming consider these factors when developing course materials or student assistance programs.  相似文献

There have been many efforts to conceptualise literacy, both in terms of its essence and component parts, but it has proved difficult to define. This paper considers work that is undertaken with children and older learners with sensory needs in order to promote the early stages of literacy. Recent government initiatives aimed at fostering literacy development have caused teachers of children with sensory needs to re-examine their practice. The paper discusses early literacy as part of children's attempts to communicate and describes children with sensory needs engaging in a range of activities that are termed 'literacy' by those working with them. By taking into account these activities, the authors endeavour to throw light on the broader questions around concepts of literacy.  相似文献

Many children with severe disabilities do not perform basic daily living skills needed for typical school and home environments. Previous research on literacy-based behavioural interventions (LBBIs) has shown promise for promoting skill acquisition and maintenance in some learners; however, only one study has examined the effectiveness of this intervention when delivered by peers. In this study, peer classmates were taught to deliver an LBBI story that highlighted hand-washing skills in three students with severe disabilities. Results showed that the accuracy of students’ new skills increased dramatically after their peers delivered the stories with pictures and printed words, and these skills maintained after the LBBI stories were removed. Further, each of the students demonstrated accurate hand-washing in novel environments using different sinks. This study builds on previous LBBI studies by incorporating peers into the story delivery, and using the intervention to teach new self-care skills.  相似文献

In this study of Kipling's Puck books, I attempt to clarify the enduring characteristics of the time-slip story as he and E. Nesbit invented it and also to determine his own distinctive contribution to the genre. Although his formal procedures were not influential, his genius lies in showing us the mere uncounted folk of history, not the big players of E. Nesbit's stories. As a conservative democrat, he shows what treasures are hid on one's own hearth and doorstep, so to speak, so that you do not have to venture far to find magic. For Kipling, that magic resides in the common culture of England, the surviving traditional ways, which catastrophic changes over two thousand years had not greatly altered. The magic is traced to the nature of the land itself, a place deeply enchanted and manifest in the merry supernaturalism that G. K. Chesterton saw in Shakespeare's A Midsummer Night's Dream.  相似文献
