As part of a larger research project aimed at transforming preK-8 mathematics teacher preparation, the purpose of this study was to examine the extent to which prospective teachers notice children’s competencies related to children’s mathematical thinking, and children’s community, cultural, and linguistic funds of knowledge or what we refer to as children’s multiple mathematical knowledge bases. Teachers’ noticing supports students’ learning in deep and meaningful ways. Researchers designed and enacted a video analysis activity with prospective teachers in their mathematics methods course. The activity served as a decomposition of practice in order to support prospective teachers in engaging in an approximation of the practice of noticing. Our findings showed that prospective teachers evidenced noticing of mathematics teaching and learning as early as the mathematics methods course. We also found that the prompts and structure of the activity supported prospective teachers by increasing their depth of noticing and their foci in noticing, moving from attending primarily to teacher moves (and merely describing what they saw) to becoming aware of significant interactions (and interpreting effects of these interactions on learning). Implications for teacher educators interested in designing and enacting activities to support noticing are discussed. 相似文献

Academic accommodations for students experiencing disabilities are increasingly available at postsecondary institutions. More studies of the efficacy of accommodations for student success are warranted, however. Given the increased gender gap in university participation, more focus on the unique impact of gender is also needed. Using a sample of students registered with Access and Inclusion Services with learning disabilities (LD), attention-deficit/hyperactivity disorder (ADHD), and combined LD/ADHD at a Canadian undergraduate university (N = 661), we explored the impact of gender on academic performance and accommodation usage. Next, we examined how gender intersected with the impact of academic accommodations on academic performance. Women, on average, demonstrated better academic performance. Academic strategies and assistive technologies were not associated with higher academic performance. However, testing accommodations (extended time and environmental accommodations) were positively associated with academic performance for men with LD or ADHD, but not for the combined group LD/ADHD. For the former two, the more tests accommodated, the higher the academic performance. Furthermore, this gender association was most prominent for students experiencing ADHD. Interpretations and policy recommendations related to these findings are presented. 相似文献

Objective: With Web 2.0, the variety of information sources for parents of paediatric psychiatric patients has increased dramatically. Information use theory suggests newer sources supplement rather than supplant traditional sources of health information. This study sought to determine the use and value of traditional and emerging sources of information and whether the subjects had access to highly valued sources of information. Methods: One hundred parents indicated the use and value of six sources of information on the child’s symptoms, diagnoses and treatment. The data were analyzed to determine if significant relationships existed between type of source and the use and value of the information sources. Results: Ninety‐four percent of the subjects had access to the Internet and almost half of those reported using the Social Web. Eighty‐five percent had at least one high‐value information source. The psychiatrist in the clinic, the Internet and the primary care physician were the most highly used and valued sources. Conclusion: Use of digital information sources was greater than found in other studies of similar populations. This use appears to complement rather than supplant more traditional sources. Further studies are needed to see if the negative impact of lack of Internet access is replicated. 相似文献

Eight trained male cyclists who competed regularly in track races, were studied under control, alkalotic (NaHCO3) and placebo (CaCO3) conditions in a laboratory setting to study the effect of orally induced metabolic alkalosis on 60 s anaerobic work and power output on a bicycle ergometer. Basal, pre- and post-exercise blood samples in the three conditions were analysed for pH, pCO2, pO2, bicarbonate, base excess and lactate. All blood gas measurements were within normal limits at basal levels. There were significant differences in the amount of work produced, and in the maximal power output produced by the cyclists in the experimental condition when compared to the control and placebo conditions (P less than 0.01). The post-exercise pH decreased in all three conditions (P less than 0.05) and post-exercise pCO2 increased significantly in the alkalosis trial (P less than 0.01). In the alkalotic condition, the pre-exercise base excess and HCO3- levels were both higher (P less than 0.05) than the basal levels, suggesting that the bicarbonate ingestion had a significant increase in the buffering ability of the blood. Post-exercise lactate levels were significantly higher (P less than 0.05) after the alkalotic trial when compared to the other two conditions, immediately post-exercise and for the next 3 min. Post-exercise lactate levels were higher than basal or pre-exercise levels (P less than 0.001). This was true immediately post-exercise and for the next 5 min. The results of this study suggest that NaHCO3 is an effective ergogenic aid when used for typically anaerobic exercise as used in this experiment. We feel that this ergogenic property is probably due to the accelerated efflux of H+ ions from the muscle tissue due to increased extracellular bicarbonate buffering. 相似文献

Brief critiques are offered of Mahner and Bunge's disjunction between the religious convictions and the scientific work of scientists, and of the substantial omissions, especially in the historical sources, they use. The historical background is extended to the encapsulated cosmology of the tribal Greeks, to the dualism of the Greek Enlightenment, and to the major Judaeo-Christian paradigm changes in cosmology, especially in the desacralization of space, time and matter, that rendered science possible. The historical development of this paradigm and the current positive interaction between science and theology are outlined. Finally, the reductionist position of Mahner and Bunge is reversed, and their epistemology queried. *** DIRECT SUPPORT *** AJ102003 00005 相似文献

This paper examines the close relationship between literacy and history in terms of the processes of historical enquiry and the literary outcomes of the historian’s work. It highlights the rich resource which historical documents represent for the primary classroom in a wide range of genres, and suggests that such documents can be used in their original form with all ability ranges. The means by which this can be done is presented in a case study of an integrated approach to teaching history, literacy and music, in a Year 6 class. The key to the success of the reading and writing activities was the use of varied teaching approaches including storytelling, drama, singing and discusssion as ways into challenging texts. The children used the concept of time and the listing of jobs as organisers for their extended writing. The careful scaffolding through text‐marking and the recording grid, as well as the emotions stimulated through the texts and activities, ensured success for all the children. The study emphasises the links between these genuine historical tasks, and activities in the National Literacy Strategy and suggests how music might be successfully integrated. 相似文献

This study examines children’s perceptions of the achievement goals parents and teachers emphasize for them in mathematics, and the relation of these goals to children’s personal achievement goals, self-efficacy beliefs, and coping strategies. Results indicated that children’s perceptions of both parent and teacher mastery and performance goal emphases predicted children’s personal goals. Further, children’s personal goals mediated the relation between perceived parent and teacher goal emphases and children’s efficacy beliefs and coping strategies. Children’s perceptions of parent and teacher emphasis on performance goals varied slightly by gender but not ethnic background, whereas variance across groups in perceptions of mastery emphases did not reach practical significance. Relations between goal perceptions, personal goals, efficacy and coping strategies also did not vary by gender or ethnic background. Implications for future research regarding the goals children perceive to be emphasized in home and school contexts, and their importance for children’s adaptive beliefs and behaviors in mathematics, are discussed. 相似文献
