This paper draws on findings of comparative international research on students’ poetic writing about the natural environment in the context of the classroom and a naturalistic setting. The study involved 97, nine- to 10-year-olds in four classes: two classes were in an English primary school with their counterparts in a Western Australian primary school. One class in each school had vicarious contact with nature as a stimulus for writing, using a previously taught technique for writing poetry; the other class in each school used the same technique but had direct contact with nature. The study has implications for students’ literacy development, creativity and agency and suggests that students’ poetic writing is enhanced through direct contact with nature. Teachers in both England and Australia, countries where ‘high stakes’ testing dominates the literacy curriculum, may find that standards of writing improve when students are given direct contact with natural spaces and are scaffolded to elicit their poetic voice. 相似文献

This study examined the effects of teachers’ biology-specific dimensions of professional knowledge – pedagogical content knowledge (PCK) and content knowledge (CK) – and cognitively activating biology instruction, as a feature of instructional quality, on students’ learning. The sample comprised 39 German secondary school teachers whose lessons on the topic neurobiology were videotaped twice. Teachers’ instruction was coded with regard to cognitive activation using a rating manual. Multilevel path analysis results showed a positive significant effect of cognitive activation on students’ learning and an indirect effect of teachers’ PCK on students’ learning mediated through cognitive activation. These findings highlight the importance of PCK in preservice biology teachers’ education. Items of the rating manual may be used to provide exemplars of concrete teaching situations during university seminars for preservice teacher education or professional development initiatives for in-service teachers. 相似文献

This study was conducted to examine the relationship between prenatal exposure to drugs and parenting stress and child maltreatment. The sample was comprised of 48 subjects including 24 drug-exposed children and a comparison group of 24 non-drug-exposed children matched on age, race, gender and socioeconomic status. The subjects' age ranged from 1 to 33 months with a mean of 13 months. As predicted, mothers who used drugs during pregnancy reported higher levels of stress than foster mothers and comparison mothers on total parenting stress, child related stress, and parent related stress as measured by the Parenting Stress Index (Abidin, 1990). Biological mothers and foster mothers of drug-exposed infants scored higher than comparisons on child-related stress, most notably in the areas of hyperactivity, distractability and adaptability. A strong association was found between maternal use of drugs and child maltreatment serious enough to necessitate removal of the children by CPS. Over 40% of the drug-exposed children were in foster care, most often with maternal grandmothers. Most mothers who used drugs during pregnancy were polysubstance abusers and 21% were intravenous drug users increasing the risk of HIV infection for mothers and children. Implications for intervention are discussed. 相似文献

The majority of the objects found in the textiles collection at the German Historical Museum in Berlin have been treated with different biocides at various points in the past. Prior to this study, the presence of organochlorinated pesticides in rooms and storage cabinets had already been proven in an analysis of air samples that employed gas chromatography and mass spectroscopy. To estimate the risks these toxins pose to both collections and museum staff, we conducted a field study with the help of a portable X-ray fluorescence spectrometer. In this study, we present an attempt at a reliable quantitative analysis. In addition to chlorine, other potentially hazardous elements such as lead, arsenic, and mercury were found in the majority of the objects. In some cases, however, it has to be taken into account that the detected elements might have originated from manufacturing processes rather than biocide treatments. Such knowledge is a crucial prerequisite to proper risk prediction. 相似文献

Harper Lee’s novel To Kill a Mockingbird is one of the most widely taught texts in language arts classrooms through the English-speaking world and is greatly valued by many readers today for its depiction of youth grappling with racism in the American South of the Depression Era. However, the novel’s subtle and sustained critique of public education has remained largely unrecognised. This essay identifies in the novel an underlying nostalgia for the past homeschooling of Southern white aristocracy as well as disdain for modern public institutions and for the democratic values that those institutions seek to instil in youth. 相似文献
