This study examined low-income African American and European American preschoolers' socioemotional causal attributions. Forty-seven Young (M = 48 months) and Old (M = 62 months) preschoolers were asked to justify a puppet's current emotion and to talk about their past emotional experiences. Responses were coded for Causal Theme and Clarity. Old preschoolers were twice as likely to attribute interpersonal themes, and Young preschoolers were 4 times more likely to generate causal themes that were uncodeable. In terms of clarity, children provided clearer responses for anger and fear than they did for happiness. Old preschoolers' explanations for emotions were clearer than young preschoolers' and young African Americans', who had the most difficulty explaining emotions. Results indicate that younger preschoolers, particularly young African Americans, may need help articulating emotions. Suggestions for how adults can scaffold preschoolers' emotional reasoning are discussed. 相似文献

Two experiments tested the motivational role of the US in classical conditioning of the rabbit’s nictitating membrane (NM) response. In Experiment 1, subjects were trained to an intermediate performance level and then given a series of (1) CS-US trials, (2) “backwards” US-CS trials, (3) CS-alone trials, (4) US-alone trials, or (5) no-stimulus presentations. Interpolated presentations of the US, either alone or in a backwards contingency, tended to produce an impairment of subsequent acquisition. In Experiment 2, subjects were trained with strong or weak US intensity on paired or interpolated trials. US intensity on interpolated trials had only a very small effect, whereas the effect of US intensity on paired trials was quite large. Shifts in paired-trial US intensity produced corresponding shifts in performance, but shifts in the intensity of the interpolated US produced no apparent effect. We conclude that the arousal of motivation is not sufficient to maintain performance in classical NM conditioning. 相似文献

In three experiments, we investigated the optimal presentation of graphic organizers (GOs) and text by having undergraduates
read a chapter-length text in its entirety, a few pages at a time, or a few sentences at a time, before or after viewing seven
GOs in their entirety (large bites), one at a time (small bites), or one cell at a time (animated). Large bites were better
than small bites for learning concept relations and applying that knowledge, and for recalling macropropositions when the
GOs were presented before text. Animated GOs offered no advantages over the large-bites GOs at first presentation and considerably
extended total study time. Presenting several GOs first, followed by the entire text, appears to be optimal in directing students’
attention to across-chapter relations in text. 相似文献

This article considers the role of literacy in the lives of four people with physical disabilities. Interviews with them reveal that despite experiencing potential barriers to participating in literacy activities, literacy is nevertheless an important dimension to their identities. Limitations of the traditional models of disability and literacy are explored and alternative, social models are found to offer a more helpful framework, in which engagement with text is seen in the context of people's lives. It is suggested that interventionists still have some way to go before their practice will fully reflect these perspectives. 相似文献

Advice to schools on countering bullying has emphasised the need for a whole school approach. This implies close collaboration between students and teachers. Little attention, however, has been paid to how students view the prospects of such collaboration. Two student surveys (n=7091 and n=632) were conducted among Australian adolescent schoolchildren, average age 14 years. The results suggest that approximately 40% of the students believed that teachers were not usually interested in taking action to stop bullying and a similar proportion were either opposed or unsure whether they should collaborate. Multiple regression analysis indicated that students who were more involved in bully/victim encounters as either as bullies or as victims were more likely than others to disparage the conflict resolution skills of teachers. In addition, bullies were particularly inclined to judge teachers as unfair in their behaviour toward students. The implications of these findings for the implementation of whole school approaches to conflict and bullying and for teacher education are discussed. 相似文献

Research at the Language Teaching Research Unit of Brighton Polytechnic has focussed on two questions. The first is the use of CCTV as a catalyst for social interaction and the development of individual communication skills and the second has been the use and effectiveness of broadcast foreign language courses, both for adults and in schools. The first stage of the research of this second focus was a large‐scale national enquiry, backed up by tests, classroom observation and in‐depth interviews. This is now being followed up by two projects, one investigating a postulated need for a support strategy to consolidate the motivation of adult home‐learners, and the other exploring the role of the teacher's expectations and attitudes in his mediation of broadcast material in the school classroom 相似文献

Prediction of School Outcomes Based on Early Language Production and Socioeconomic Factors 总被引:7,自引:0,他引:7
Early differences in family SES, child language production, and IQ were related to outcomes in early elementary school in the present prospective, 10-year longitudinal study. In a prior study of family interactional variables associated with language learning, major differences in parenting (i.e., time, attention, and talking) were found to be associated with differences in child productive vocabulary between 7 to 36 months of age, and child IQ, favoring higher-SES parents. Lower-SES children were exposed less often than higher-SES children to diverse vocabulary through their parents' attention and talking, and they were prohibited from talking more often. In the current study, 32 children involved in the earlier study were repeatedly assessed between 5 to 10 years of age, while in kindergarten through third grade. Results indicated that SES-related differences in child language prior to school were predictive of subsequent verbal ability, receptive and spoken language, and academic achievement assesed on standardized tests in kindergarten through grade 3. However, none of the predictor variables were related to direct measures of elementary schooling. When combined with a composite SES indicator, early child language production significantly increased the variance accounted for in the prediction of elementary language and academic competencies in each subsequent year in elementary school. Implications are discussed in terms of the stability of performance on language and academic performance measures of children who entered school with different early language learning experiences, and the need to consider early home- and school-based intervention designed to prevent or ameliorate these trends. 相似文献

This study examined the protective effects of religiousness and parent involvement for the development of conduct problems beyond the effects of risk factors. Measures of violence exposure, conduct problems, parent involvement, and religiousness, from the longitudinal Social and Health Assessment survey, were completed by 1,703 high-risk urban adolescents (12.5 +/- 1.7 years; 53% female). Witnessing of and victimization by community violence appeared to be significant risk factors for an increase in conduct problems over a 1-year period. Religiousness and parental involvement were each uniquely associated with a decrease in conduct problems. Moreover, several dimensions of religiousness moderated the relationship between violence exposure and conduct problems, buffering the negative effects of violence exposure. Implications of these findings for prevention efforts are discussed. 相似文献

ABSTRACTIn the last two decades, we have witnessed a rapid expansion of higher education in Mainland China and Taiwan, recording a significant increase in higher education enrolments in these two Chinese societies. The massification of higher education in China and Taiwan has inevitably resulted in an oversupply of university graduates, with growing social concerns for skills mismatches being found in the labour market, stagnant graduate employment and social mobility. This article critically examines how university students and graduates in these two Chinese societies reflect upon their employment experiences. Human capital theory predicts that other things being equal, raising participation in higher education will initially increase inequality as rates of return rise, and then it will reduce inequality as expansion reaches mass levels and rates of return decline. If the output of graduates outpaces the demand for their skills, which appears to be the current case in many countries, then supply and demand pressures reduce the pay premium for degrees and lower income inequalities. However, this study clearly demonstrates that the massification and the universalisation of higher education in Mainland China and Taiwan, respectively, have actually intensified inequality. 相似文献
