Just two tablets enough to cause long-term health problems, psychologists (心理学家) are told Ecstasy (摇头丸), the so-called (所谓的) love drug taken by hundreds of thousands each weekend, can result in crippling depression after just a couple of tablets, a study revealed. 相似文献

ABSTRACTThis paper describes the aims, origins and principles of the Australian National Exceptional Teaching for Disadvantaged Schools programme and reflects on findings from its first eight years. As a well-established, mainstream university-based initial teacher-education programme designed to prepare social justice teachers for low socio-economic or high-poverty schools, NETDS has had significant impact on recruiting and retaining high-performing teachers in the schools that need them most. In this paper we discuss how it works, but also outline some of the complexities that arose in trying to design a teacher-education programme with equity at the centre and some of the changes we made along the way. 相似文献

What proficiencies are brought tobear when students work on mathematicsproblems? And to what extent may these becaptured by knowledge categories? These arequestions that I consider in this article,as I explore notions of competency, that gobeyond knowledge to include themathematical `dispositions' that studentsbring to problems and the `practices' withwhich they engage. This exploration willdraw from two frameworks that have recentlybeen introduced in the US. In addition, Iconsider the ways in which researchknowledge is conceived and developed,reflecting upon the important role oftheory and the potential of `workinghypotheses' for connecting with practice innew ways. 相似文献

Twenty‐three preschool‐age children, 3;6 (years; months) to 4;1, were videotaped separately with their mothers and fathers while each mother and father read a different unfamiliar storybook to them. The text from the unfamiliar storybooks was parsed and coded into story grammar elements and all parental extratextual utterances were transcribed and coded for (1) their relationship to the story grammar elements found within the storybook, and (2) the natural strategies parents used to direct their children's attention to these elements. Children's overall exposure to story grammar elements during book reading was also explored for its relationship to their language abilities. Results indicated that parents focused significantly more on the resolution, attempt, and consequence compared to the initiating event and plan, and most frequently used the text and pictures as strategies for recruiting their children's attention to the story grammar elements within the book. In addition, the frequency of parental utterances related to story grammar elements was negatively correlated with children's language abilities. This study did not examine the complexity or depth of parental utterances related to story grammar elements. These findings provide initial evidence that children may derive their understanding of story grammar at least in part through their parents' extratextual discussions during parent–child book reading. 相似文献

This study aims at investigating the profiles of teacher educators in order to explore their ability to prepare preservice teachers for technology integration in education. Specifically, the current study examines whether teacher educators can be grouped on the basis of their attitudes toward ICT (in education), their ICT self-efficacy to design ICT-rich learning environments, their competencies to use ICT in their teaching practice and the strategies they use to prepare preservice teachers for technology integration. These strategies are included in the SQD (Synthesis of Qualitative Data) model and comprise: (1) teacher educators as role models, (2) reflecting on the role of technology in education, (3) learning how to use technology by design, (4) collaboration with peers, (5) scaffolding authentic technology experiences and (6) providing continuous feedback. Data were collected from a sample of 284 teacher educators in Flanders, the Dutch-speaking part of Belgium, and submitted to latent profile analysis. The added value of the current study lies in the account of how SQD strategies and a typical set of determinants of ICT integration can be associated within teacher educators’ profile. Based on the profiles emerging from this study, teacher training institutions should consider their teacher educators to be gatekeepers when preparing future generations of teachers for the learning environments of the twenty-first century. In the discussion section, the implications for practice and future research are discussed. 相似文献

The low status of the foundation subjects (e.g. Music and Physical Education (PE)) in English primary schools is well documented. Using PE as an illustrative example, a thematic analysis of 51 PE trainee students’ assignments, based on their perceptions of a two-week experience in a primary school, highlighted a number of areas of concern (e.g. limited/inadequate preparation; insufficient teacher knowledge/confidence; variable/limited subject leadership and non-qualified teachers delivering the curriculum). The possibility of teachers, coaches and other external specialists learning collaboratively with and from each other within a community of practice/learning is proposed as one way of strengthening the foundation subjects within the primary school curriculum. 相似文献

Pigeons were trained to match temporal (2 and 8 sec of keylight) and color (red and green) samples to vertical and horizontal comparison stimuli. In Experiment 1, samples that were associated with the same correct comparison stimulus displayed similar retention functions; and there was no significant choose-short effect following temporal samples. This finding was replicated in Phase 1 of Experiment 2 for birds maintained on the many-to-one mapping, and it was also obtained in birds that had been switched to a one-to-one mapping by changing the comparison stimuli following color samples. However, in Phase 2 of Experiment 2, when the one-to-one mapping was produced by changing the comparison stimuli following temporal samples, a significant choose-short effect was observed. In Experiment 3, intratrial interference tests gave evidence of temporal summation effects when either temporal presamples or color presamples preceded temporal targets. This occurred even though these interference tests followed delay tests that failed to reveal significant choose-short effects. The absence of significant choose-short effects in Experiment 1 and in Phase 1 of Experiment 2 indicates that temporal samples are not retrospectively and analogically coded when temporal and nontemporal samples are mapped onto the same set of comparisons The interference test results suggest that the temporal summation effect arises from nonmemorial properties of the timing system and is independent of the memory code being used 相似文献

Becoming literate in Chinese: a comparison of native‐speaking and non‐native‐speaking children 下载免费PDF全文

How do native Chinese‐speaking (CS) and non‐Chinese‐speaking (NCS) children learn to read and write in Chinese? In the present study, 29 CS and 34 NCS second and third graders aged 76 to 122 months (M = 93.65) participated in an experiment where they were taught 16 new Chinese characters in one of four conditions – copy, radical, phonological and look–say. Results showed that the copying condition best facilitated writing of Chinese characters for both groups, whereas radical knowledge facilitated only CS children's writing. NCS children benefited more from the phonological condition than from the look–say condition in learning to read Chinese. These results highlight the effectiveness of copying practice for all children learning to write Chinese. However, approaches to reading and writing Chinese may differ somewhat depending on the Chinese background knowledge of the children as well. Teaching children Chinese should be geared towards the strengths of different groups for learning. 相似文献
