Event-related potentials (ERPs) were recorded from 27 children (14 girls, 13 boys) who varied in their reading skill levels. Both behavior performance measures recorded during the ERP word classification task and the ERP responses themselves discriminated between children with above-average, average, and below-average reading skills. ERP amplitudes and peak latencies decreased as reading skills increased. Furthermore, hemisphere differences increased with higher reading skill levels. Sex differences were also related to ERP amplitude variations across the scalp. However, ERPs recorded from boys and girls did not differ as a function of differences in the children's reading levels.  相似文献

2 strategies were used to investigate the continued impact of early experience and adaptation given subsequent experience and/or developmental change in a poverty sample (N = 190). Groups were defined whose adaptation was similar during the preschool years but consistently different earlier; then these 2 groups were compared in elementary school. In addition, a series of regression analyses was performed in which variance accounted for by near-in or contemporary predictors of adaptation in middle childhood was removed before adding earlier adaptation in subsequent steps. Children showing positive adaptation in the infant/toddler period showed greater rebound in the elementary school years, despite poor functioning in the preschool period. Regression analyses revealed some incremental power of early predictors with intermediate predictors removed. The results were interpreted as supporting Bowlby's thesis that adaptation is always a product of both developmental history and current circumstances. While this research cannot resolve such a complicated issue, it does point to the need for complex formulations to guide research on individual development.  相似文献

This project represents a replication of Russ, Simonds, and Hunt’s (2002) project that explored the influence of instructor sexual orientation disclosure on perceptions of teacher credibility and learning. Our purpose was to see if the original findings—that students perceive gay teachers as less credible and that they learn less than from a straight teacher—could be replicated in a sample of students from a different location and after more than 15 years from the original study. Employing a quasi-experimental methodology, we did not find the same result as they did: gay instructors were not rated lower in credibility and learning by the students in our sample. We provide some context and discussion around why this might be the case.  相似文献

This paper analyses the concerns, parameters and silences emerging in the field of English research on contemporary educational restructuring. The research effort oriented to the investigation of Thatcherism and the marketisation of education is documented. Its strong emphasis on markets and processes of marketisation and its neglect of alternatives to Thatcherism is noted. This pattern of emphases and silences in research seems to have arisen as a result of changes in the research‐policy context, and because of the way Thatcherism has been conceptualised in educational research. I argue that these developments have encouraged a narrowing of both research and political horizons in education. I suggest that a more comprehensive framework for analysing educational restructuring can be developed by recontextualising Thatcherism and drawing on recent social science research on institutional design. Such a framework would appear to offer a basis for tackling the empirical and normative work of assessing probable futures and the possibilities of preferred futures in the practical work of education reform.  相似文献

This article provides insight into different expectations between Chinese and British academic culture for distance learning. The article is based on a pedagogic research project, a case study, and is centered on a distance learning course in maritime law proposed by a British university for a university in China. Some important commonalities and gps between perceptions of deliverers and receivers of the proposed course were identified. There were important differences between Chinese and UK respondents about the value of open educational resources, the sequential access to course materials, the type of technologies that were important for delivery of content and for communication, the value of peer assessment, and the time expectations for feedback. Recommendations are suggested for bridging the cultural gaps in distance learning between a British and Chinese context.  相似文献

In Experiment 1, a group of rats were runway trained on each of two reward series for 32 days. The two series consisted of three runs, the first two of which were, respectively, rewarded and nonrewarded; the third run was rewarded in one series but nonrewarded in the other. A 40-min interval separated the two series; the first and second runs within the series were separated by a 10-min interval, whereas the second and third runs were separated by a 30-sec interval. The reward (and nonreward) events and temporal cues of the two series are designated R-NR/R-NN. A second group was similarly trained, with the exception that the 10-min interval separated the second and third runs (RN-R/RN-N). Both groups developed appropriate differential running on the third run of the two series, and the RN-R/RN-N animals ran appropriately (slowly) on the second run of both series. Appropriate Run 2 performance appeared in one half of the R-NR/R-NN animals (depending upon order of series presentation); the remaining half ran faster on Run 2 of the R-NR series than on the same run of the R-NN series, an effect currently termed interevent anticipation. A cue shift phase in which all within-series intervals were 30 sec showed that the temporal intervals were controlling performance before the shift. Experiment 2 showed that interevent anticipation appears when all within-series intervals are either 10 min or 30 sec from the beginning of training, suggesting that the elimination of interevent anticipation in Experiment 1 was due to the differential cuing of runs by the temporal intervals rather than the particular interval duration. The overall findings suggest that the similarity of Run 2 and Run 3 performance termed interevent anticipation may be due to a failure to discriminate the ordinal position of runs within a series.  相似文献

The present study sought to examine whether preschool children's emotion regulation, problem behaviors, and kindergarten behavioral self-regulation in the classroom were predictors of kindergarten achievement scores. The children (N = 122, 47% male and 63% European American) who were participating in an ongoing longitudinal study, were seen at both a preschool and kindergarten assessment. The present study examined the relation between parent report, teacher report, and laboratory measures of regulation and children's achievement test scores. Children's emotion regulation and behavioral self-regulation in the classroom were related to all measures of achievement. The relation between preschool emotion regulation and kindergarten achievement was mediated by behavioral self-regulation in the kindergarten classroom. In addition, all measures of regulation were correlated, suggesting that some children who have difficulty regulating their behavior in one setting (such as home) may also have difficulty with regulation in other settings (such as school).  相似文献
