加拿大英语除了具有鲜明的创新性特点以外,其保守性特点也很突出。18世纪末英国殖民者将当时的英语带到北美。随着时代的变迁,英语在祖国发生了变化,但大洋彼岸因种种因素没有发生同样的变化。因此在今天的加拿大英语中却仍可寻到昔日英国英语的痕迹。这在语音、词汇和语法方面均有体现。加拿大英语保守性特点的成因主要有语言接触因素、社会因素和移民源的心理因素。通过对加拿大英语保守性特点及其成因的分析,有助于英语的学习与传播。 相似文献

Home advantage in team games is well proven and the influence of the crowd upon officials' decisions has been identified as a plausible cause. The aim of this study was to assess the significance of home advantage for five event groups selected from the Summer Olympic Games between 1896 and 1996, and put home advantage in team games in context with other sports. The five event groups were athletics and weightlifting (predominantly objectively judged), boxing and gymnastics (predominantly subjectively judged) and team games (involving subjective decisions). The proportion of points won was analysed as a binomial response variable using generalized linear interactive modelling. Preliminary exploration of the data highlighted the need to control for the proportion of competitors entered and to split the analysis pre- and post-war. Highly significant home advantage was found in event groups that were either subjectively judged or rely on subjective decisions. In contrast, little or no home advantage (and even away advantage) was observed for the two objectively judged groups. Officiating system was vital to both the existence and extent of home advantage. Our findings suggest that crowd noise has a greater influence upon officials' decisions than players' performances, as events with greater officiating input enjoyed significantly greater home advantage. 相似文献

Two studies of second graders at risk for reading disability, which were guided by levels of language and functional reading system theory, focused on reading comprehension in this population. In Study 1 (n = 96), confirmatory factor analysis of five comprehension measures loaded on one factor in both fall and spring of second grade. Phonological decoding predicted accuracy of real-word reading; automatic letter naming predicted rate of real-word reading; accuracy and rate of both real-word reading (more so than decoding of pseudowords) and text reading predicted reading comprehension; and Verbal IQ also predicted reading comprehension. In Study 2 (n = 98), the treatment group (before/after school clubs receiving an integrated instructional approach that was supplementary to the general reading program) improved significantly more in phonological decoding and state standards for reading fluency than the control group (general reading program that had some code instruction but emphasized comprehension). The rate of phonological decoding explained 60.3% of real-word reading. Both treatment and control children improved significantly in reading comprehension, but controlling for pretreatment individual differences in oral vocabulary or in phonological decoding eliminated this effect. Taken together, the results of the two studies support two paths to reading comprehension: one from vocabulary and verbal reasoning, and one from written language that has multiple links between subskills: (a) alphabetic principle --> phonological decoding, (b) automatic phonological decoding --> accurate real-word reading, (c) automatic letter coding ---> automatic word reading, and (d) automatic word reading --> fluent text reading. Instructional implications of both paths and the links within the written language are discussed. 相似文献

In this article, we report on a study that investigated the motivational (e.g. intrinsic motivation) and dispositional variables (e.g. attitudes) that determine teachers’ intention to use or not to use digital learning materials (DLMs). To understand the direct and indirect relationships between these variables, we replicated a study in which self-determination theory (SDT) and the theory of planned behaviour/integrated model of behaviour prediction (IMBP) are combined and a distinction was made between global level psychological needs, and contextual level as well as situational level motivational constructs. Using a sample of 1273 teachers, our preliminary findings support the findings of the previous study. The combined model potentially provides us with a more comprehensive explanation of teachers’ volitional behaviour regarding their use of DLMs in their pedagogical practices than would be possible on the basis of SDT or IMBP alone. 相似文献

Despite that benefits of feedback in student learning are reported in much research, little has been reported regarding the use of feedback from teachers to other teachers—a key tool in professional development. In this study, we triangulated data from videotaped peer coaching sessions, questionnaires, and interviews regarding 12 primary school teachers in four peer groups in the Netherlands. We focused our research on two issues: the interplay of observed feedback dimensions and elements and perceptions of that feedback. Feedback dimensions were generally effective and the influence of the elements on the dimensions mostly aligned with the expectations. Teachers generally perceived feedback as effective. Moreover, effective observed feedback was perceived as effective. Findings indicate that peer coaches should stimulate coached teachers to become goal directed, specific, detailed, and neutral (neither positive nor negative) by using feedback elements so as to optimize feedback processes. 相似文献

The history of science shows a shift from single-investigator ‘little science’ to increasingly large, expensive, multinational, interdisciplinary and interdependent ‘big science’. In physics and allied fields this shift has been well documented, but the rise of collaboration in the life sciences and its effect on scientific work and knowledge has received little attention. Research in biology exhibits different historical trajectories and organisation of collaboration in field and laboratory – differences still visible in contemporary collaborations such as the Census of Marine Life and the Human Genome Project. We employ these case studies as strategic exemplars, supplemented with existing research on collaboration in biology, to expose the different motives, organisational forms and social dynamics underpinning contemporary large-scale collaborations in biology and their relations to historical patterns of collaboration in the life sciences. We find the interaction between research subject, research approach as well as research organisation influencing collaboration patterns and the work of scientists. 相似文献

Instructional Climate in Dutch Secondary Education 总被引：1，自引：0，他引：1

Research, aimed at constructing an instrument for measuring instructional climate, was conducted in 121 Dutch schools for senior general secondary education. The instrument comprised scales for students, teachers, heads of department and principals. All scales proved to be sufficiently reliable and valid. The results show that the following variables are significantly related to students' results in mathematics: students' enjoyment of mathematics; students' attitude towards high grades; students' enjoyment of learning; appreciation of how teachers prepare students for tests; students' appreciation of the teacher as a person; students' appreciation of teaching abilities; an orderly instructional climate in the classroom; frequent monitoring of student results; emphasizing achievement by teachers; and the principals' emphasis on a task oriented climate. 相似文献

In South Africa, recent government plans tochange the institutional landscape of highereducation have resulted in mergers of collegesinto universities or technikons. The researchreported in this article focuses solely on theimpact of a ``college-into-university'incorporation as manifested in the personal,emotional and career experiences of thesecollege staff members. It traces the changes intheir perceptions and emotions during and afterthe incorporation process. It also identifiesrecurring themes and issues evident in thepersonal lives of those affected by thisincorporation.A unique research methodology was engaged: TheCollege staff who had been appointed to theuniversity after the merger, identified sevencritical themes and then designed and conducted30 semi-structured interviews among themselves.This article thus documents the impact ofincorporation into a university on theindividual and collective lives of theresearchers themselves.The data suggest that the emotional impact ofincorporation was intense and that theuncertainty, especially, led to considerabletrauma. The most important concern emanatingfrom this joint research project is that whilea certain degree of distress is unavoidable inany institutional merger, inattention to themanagement of human resources, emotions andaspirations could linger on, possibly having anegative effect on the ambitions for thetransformation of the new entity. 相似文献
