This study investigates the unexpected emergence of a community of practice in a middle level mathematics and science methods course. The authors describe how preservice teacher participation in a collaborative, project-based service-learning experience resulted in the formation of a community of practice characterized by teamwork, meaningful practice, and shared resources. The article concludes with a twofold argument demonstrating how collaborative, project-based service-learning experiences potentially contribute to preservice teacher learning via the positive outcomes that emerge from participation in a community of practice, while also reinforcing preservice teacher commitment to the constructive pedagogy of service-learning. 相似文献

AbstractThe aim of this study was to investigate the effects of a single bout of whole-body vibration (WBV) on running gait. The running kinematic of sixteen male marathon runners was assessed on a treadmill at iso-efficiency speed after 10 min of WBV and SHAM (i.e. no WBV) conditions. A high-speed camera (210 Hz) was used for the video analysis and heart rate (HR) was also monitored. The following parameters were investigated: step length (SL), flight time (FT), step frequency (SF), contact time (CT), HR and the internal work (WINT). Full-within one-way analysis of variance (ANOVA) of the randomised crossover design indicated that when compared to SHAM conditions, WBV decreased the SL and the FT by ~4% (P < 0.0001) and ~7.2% (P < 0.001), respectively, and increased the SF ~4% (P < 0.0001) while the CT was not changed. This effect occurred during the first minute of running: the SL decreased ~3.5% (P < 0.001) and SF increased ~3.3% (P < 0.001). During the second minute the SL decreased ~1.2% (P = 0.017) and the SF increased ~1.1% (P = 0.02). From the third minute onwards, there was a return to the pre-vibration condition. The WINT was increased by ~4% (P < 0.0001) during the WBV condition. Ten minutes of WBV produced a significant alteration of the running kinematics during the first minutes post exposure. These results provide insights on the effects of WBV on the central components controlling muscle function. 相似文献

Cultural content analysis of EFL textbooks has received considerable attention in ELT pedagogy in recent decades. The current study investigated the representation of big “C” and small “c” cultural themes in three common EFL textbooks: Top Notch, Summit and Passages. The frequency analysis indicated that in Top Notch series, small “c” cultural themes of daily life, food, customs/norms and big “C” theme of geography were the most frequent cultural themes; while, in Summit and Passages, the most frequent small “c” cultural theme was values and beliefs. This study also investigated the correspondence between EFL teachers’ and learners’ cultural preferences on the one hand, and the match between their preferences and the cultural content of the books in question. 135 EFL learners and 36 EFL teachers responded to adapted questionnaires. The findings revealed that there were areas of match (mainly in small “c” themes) and cases of mismatch (primarily in big “C” themes) between learners’ and teachers’ preferred cultural themes and the cultural content of the textbooks analysed. 相似文献

The mathematical model determines how firms can leverage their advantages to increase their market share. Represented as vortex, firms increase their market scope using: marketing expenses strategy, R&D expenditure strategy or price reduction strategy. For an overpriced good, the R&D strategy is required if sector marketing velocity growth is low otherwise the pricing strategy is suited. Conversely, for an underpriced good, the R&D strategy is used when sector marketing velocity growth is high, but when it is low, the pricing strategy is followed. Distance between firms, competitor marketing velocity and related services share contribute or limit these strategies. 相似文献

This study investigated the effect of assessment type (self vs. peer vs. teacher) on university students’ academic achievement and students’ attitudes toward them. In the main study, 82 undergraduate English-as-a-Foreign-Language students in four classes at three universities in Iran were randomly assigned into one of self-, peer- and teacher-assessment or control groups. A pre-test was designed to measure students’ initial knowledge in the subject Teaching Methods. Then experimental groups were subjected to one of the assessment types; however, the control group received no intervention. Thirty-eight students from experimental groups completed an attitude questionnaire. A similarly designed follow-up study was conducted with two classes of BA Chemistry students taking a General English course at Urmia University. The application of one-way analysis of covariance on the main study post-test data indicated differences in performances of all groups, with peer-assessment group performing the best. Quantitative and qualitative analyses indicated that both self- and peer-assessment, as well as the teacher-assessment group, had positive attitudes toward their assessment experiences. The application of one-way analysis of variance on replication study data showed that the experimental group significantly outperformed the control group on the post-test and that students in the former group had positive attitudes toward self-assessment. 相似文献

Drawing on the expectation state theory, this paper seeks to analyse the social cognitive process of the impacts of gender stereotypes along with their culturally derived schemas of status belief, status characteristics and emotion at the early stage of women's endeavour to emerge as leaders in academia. Employing a convenience sampling and interviews held with five women academic participants from three public and private universities in the western region of Indonesia, this research reveals that two social cognitive practices affect women's endeavour to emerge as leaders; (1) the incongruities of cultural and cognitive expected status belief and status characteristics about females with the expected performance of leadership. The pervasive effect of these can be mitigated when women adopt a strategy of neglection, coupled with a strategy of networking both via their own networks and their husband's networks; (2) the incongruities of cultural and cognitive expected ways of emotional expression on women with the expected performance of leadership. This impacts the status conferral that shapes the worthiness of females to emerge as leaders, leading female leaders in our study to build a protective shield of emotion display to keep them perceived as worthy individuals for leadership roles. 相似文献

Patterns and purposes in the uses and misuses of the term ‘critical thinking’ in the social sciences
This article analyses the uses and representations of the term “critical thinking” in the social science literature, based on a qualitative content analysis of titles, abstracts and keywords retrieved from the SCOPUS database for Germany, France and Russia over the last two decades. Our analysis focuses on how the use of the term “critical thinking” has increased over time, in which contexts the term is used and in which part of article texts it is used. Our findings are counterintuitive on several levels. First, the term “critical thinking” is seldom used in a pluri-disciplinary context. More commonly, it is used within specific discourses—notably education. Second, we found that it is mainly used instrumentally, rather than analytically. Third, most of the articles that use the term do not engage in actual critical analysis. There are also important geographic variation in the use of the term. In articles from Germany and Russia the term is used in similar ways—and differently in France. These nuances are difficult to analyse however, due to the different topics addressed, as well as author preferences. The use of the term “critical thinking” is diverse; indeed, at times weak and paradoxical. Finally, we discuss how editorial policy in academic journals possibly influences the discourse on critical thinking. 相似文献
