This paper considers the work of the Russian social philosopher and cultural theorist, Mikhail Mikhailovich Bakhtin as a source of understanding for those involved in action learning. Drawing upon data gathered over two years during the evaluation of 20 action learning sets in the north of England, we will seek to work with the ideas of Bakhtin to consider their value for those involved in action learning. We consider key Bakhtin features such as Making Meaning, Participative Thinking, Theoreticism and Presence, Others and Outsideness, Voices and Carnival to highlight how Bakhtin's can enhance our understanding of the nature of action and learning. 相似文献

Young Filipino children are expected to solve mathematical word problems in English, which is not their mother tongue. Because of this, it is often assumed that Filipino children have difficulties in solving problems because they cannot read or comprehend what they have read. This study tested this assumption by determining whether presenting word problems in Filipino or reading them aloud to children in either language facilitated solution accuracy. Contrary to the initial hypothesis, reading word problems aloud did not seem to improve student performance (p > 0.10). In contrast, presenting word problems in Filipino significantly improved solution accuracy (p < 0.0001) and led to differences in error patterns – children were less likely to use an inappropriate arithmetic operation when problems were presented in Filipino. However, the language of the problem had minimal effects on the more difficult Compare problem type. Finally, the benefits of using Filipino were more pronounced for low‐achieving students who may have lower proficiency in English than their high‐achieving peers (p < 0.01). 相似文献

Awareness of the structure and meaning of morphologically complex words: Impact on reading 总被引:3,自引:1,他引:2
Many new words middle school children encounter in books they read are relatively transparent derived forms whose meanings might be figured out through analysis of the word parts. Of importance is whether students can not only read and recognize the structure of morphologically complex words but also determine their meanings. This issue was addressed by investigating the relationship of third and fifth graders' awareness of the structure and meanings of derived words and the relationship of these forms of morphological awareness to word reading and reading comprehension. The results showed that awareness of structure was significantly related to the ability to define morphologically complex words; some aspects were also significantly related to the reading of derived words. The three morphology tasks accounted for significant variance in reading comprehension at both grade levels, but the contribution was stronger for the fifth than the third grade. It may be educationally noteworthy that morphological analysis contributed significantly to reading comprehension for the third graders because they are presumably just beginning to learn to read and understand morphologically complex words. 相似文献

Eighty-nine female and 43 male special education teachers completed a battery of instruments dealing with job stress and satisfaction and social role characteristics. Social role orientation (expressive, instrumental, balanced, and undifferentiated) was determined for each of the teachers both on- and off-the-job using the Bem Sex Role Inventory, and then analysed in relation to six indices of work-related stress and satisfaction. For female special educators, a balanced social role orientation was associated with higher levels of satisfaction and lower levels of stress, while an undifferentiated orientation was associated with lower levels of satisfaction and higher levels of stress. Implications for teacher preparation programs are discussed, and suggestions for future research are included. 相似文献

Oxygen uptake kinetics in children and adults after the onset of moderate-intensity exercise 总被引:1,自引:0,他引:1
The literature suggests that the oxygen uptake (VO2) response to the onset of moderate-intensity exercise may be both mature from childhood and independent of sex. Yet the cardiorespiratory response to exercise and the metabolic profile of the muscle appear to change with growth and development and to differ between the sexes. The aim of this study was to investigate further changes in the VO2 kinetic response with age and sex. Participants completed a series of no less than four step change transitions, from unloaded pedalling to a constant work rate corresponding to 80% of their previously determined ventilatory threshold. Each participant's breath-by-breath responses were interpolated to 1 s intervals, time aligned and then averaged. A single exponential model that included a time delay was used to analyse the averaged response following phase 1 (15 s). Participants with parameter confidence intervals more than +/- 5 s were removed from the sample; the results for the remaining 13 men and 12 women (age 19-26 years), 12 boys and 11 girls (age 11-12 years) were used for statistical analysis. Children had a significantly shorter time constant than adults, both for males (19.0+/-2.0 and 27.9+/-8.6 s respectively; P<0.01) and females (21.0+/-5.5 and 26.0+/-4.5 s respectively; P<0.05). There were no significant differences in the time constant between the sexes for either adults or children (P>0.05). A significant relationship between the time constant and peak VO2 was found only in adult males (P<0.05). A shorter time constant in children may reflect an enhanced potential for oxidative metabolism. 相似文献

This article assesses the potential for US news coverage offoreign affairs to influence US public opinion about foreigncountries during the latter part of 1989 and early 1990, a timeof dramatic changes in central Europe. The study draws on twosources of data: content analysis of US network news and wireservice coverage of nine countries (West Germany, East Germany,the Soviet Union, Hungary, Poland, Great Britain, France, Japan,and Israel) over a six month period, and a nationally representativesurvey of 1,117 US adults which measured opinions about thesecountries, conducted in early 1990. The study shows that thereis an important relationship between the visibility of foreigncountries in TV news and US public opinion about these countries.TV is more important than newspapers for influencing publicopinion about foreign countries. And attention to foreign affairsnews, rather than simple exposure to news, best predicts generalliking of a country. Finally, attention to television news coveragehad a positive and significant influence on sympathy with Westand East Germany in 1990, even if one had German friends, relativesor ancestors, or had visited Europe. 相似文献

This study determined gender and ethnic differences in physical work capacity (PWC170) of 8-16-year-old American youth as they progress from elementary to high school. A multicohort group of 2,540 youth participated 50.4% girls (21.4% African Americans, and 78.6% Caucasians). PWC170 was predicted from cycle ergometer testing six times over a 7-year period. The absolute PWC170 of girls stabilized in early adolescence, while boys increased with each trial. The PWC170 relative to body weight of girls decreased steadily, whereas the boys remained stable. African Americans had greater absolute PWC170 values than Caucasians (p = .0001). The relative PWC170 was lower for African American girls than Caucasian girls (p = .0001), but there were no ethnic differences for boys (p > .05). Although correlations and grouping suggested moderate tracking; girls with high relative PWC170 tended to migrate to lower levels as they aged, where as high-peforming boys maintained their PWC170 as they aged. 相似文献
