The Effect of Questioning Style During Storybook Reading on Novel Vocabulary Acquisition of Preschoolers 总被引:1,自引:0,他引:1
The effects of adult questioning on children’s novel word acquisition during storybook reading were investigated. Three-year-olds were assigned to one of three conditions: vocabulary eliciting questions, noneliciting questions, and no questions (control). General vocabulary comprehension and novel word knowledge were equivalent across the groups before the storybook reading intervention. Children were read 3 storybooks repeatedly across 4 reading sessions and were tested for production and comprehension of novel words in the final session. Children’s novel word comprehension increased more in both question conditions than in the control condition, suggesting that type of question is not as important to word learning as children’s active engagement in discussion about novel words in general. Novel word production was not strongly affected by any of the reading conditions. However, asking children noneliciting questions did appear to foster production of new words more than not asking questions at all. 相似文献

A key tenet of the Home–School Knowledge Exchange Project is that children's learning will be enhanced if the knowledge and experience that are to be found both at home and in school can be brought together. In this paper we explore ways of connecting home and school to support literacy learning at Key Stage 1, focusing on the home‐to‐school direction. We discuss how shoeboxes, filled with children's artefacts, can support a range of literacy‐related activities in school. It is suggested that the extensive diversity of knowledge and interests reflected in the chosen objects presents teachers with an invaluable opportunity to personalise children's literacy learning. 相似文献

This research investigated students' understanding of electrochemistry following a 7–9-week course of instruction. A list of conceptual and propositional knowledge statements was formulated, and this provided the framework for semistructured interviews that were conducted with 32 students in their final year of high school chemistry, following instruction in electrochemistry. Three misconceptions identified in this study and five which have been reported earlier are incorporated into an alternative framework about electric current. The framework is grounded on the notion that a current always involves drifting electrons, even in solution. Another area where students' misconceptions were prevalent was in relation to the sign of the anode and cathode. Students who thought the anode was negatively charged believed cations would move toward it, and those who thought it was positively charged were unable to explain why electrons move away from it. Electrolytic cells also proved troublesome for students. Many students did not associate the positions of the anode and cathode with the polarity of the applied electromotive force (e.m.f.). Other students attempted to reverse features of electrochemical cells and apply the reversals to electrolytic cells. The implications of the research relate to students' interpretation of the language that is used to describe scientific phenomena and the tendency for students to overgeneralize, due to comments made by teachers or statements in textbooks. 相似文献

This article presents a case study of 10 high-profile Australian research scientists. These scientists are highly committed to engaging with the public. They interact with a wide range of groups in the community, including the traditional media. They are aware that they are seen as representatives of science at a time when the authority of science and scientists is threatened in Australia by controversy around issues such as climate change and vaccination. Through their experiences of interacting with non-scientists, they have developed views about qualities, characteristics and knowledge that contribute to, or inhibit, positive interactions between scientists and non-scientists. Their experiences and insights highlight aspects of contemporary science that are not generally acknowledged in science curricula. 相似文献

Preweanling rats, 16 days of age, responded to an olfactory conditioned stimulus (CS) paired with a shock unconditioned stimulus (US) with increases in heart rate and behavioral activation. In two experiments this finding was replicated and, in addition, it was found that the form of these conditioned responses (CRs) changed after a retention interval. When tested 24 h after CS-US pairings, the subjects displayed a decrease in heart rate accompanied by CS-elicited freezing. Giving two unsignaled shocks prior to the delayed test effectively reinstated the tachycardia and behavioral arousal CRs. The results are discussed in terms of contextual influences on the form of the CR and how changes in the magnitude of context fear may alter responding to an olfactory CS. 相似文献

This study examined the effect of a time-limited welfare program on school-age children using data on almost 3,000 children (ages 5-17 at the four year follow up-point) from the random assignment evaluation of Florida's Family Transition Program (FTP). FTP was one of the first welfare reform initiatives to impose a time limit on the receipt of cash assistance, and it combined the time limit with a rich array of mandatory services. The effects of FTP on children were moderated by families' risk of long-term welfare dependency. Contrary to predictions laid out at the outset, there were few effects of FTP on middle childhood and adolescent children for children of parents most likely to be long-term welfare dependent (those most likely to hit the time limit). However, consistent negative effects on this same age group of children were found for children of parents least likely to be long-term welfare dependent--parents who had the largest employment gains--and effects of FTP were most strongly negative for the oldest adolescent children. The findings suggest a different theoretical model for movements into employment than the one suggested in the previous literature for job loss. The findings are discussed in terms of their contribution to research and policy. 相似文献

Connecting to current work in the area of creative pedagogies, this paper reports findings of an exploratory study that sought to identify what characterises possibility thinking in young children's learning experiences and how teachers’ pedagogical practice fosters this critical aspect of creativity. It focuses in particular on pedagogy, seeking to demonstrate how approaches adopted facilitated children's possibility thinking. Possibility thinking has been conceptualised as being central to creative learning although its role, as manifest in the learning engagement of children and the pedagogical strategies of practitioners has not been fully illuminated. The co-participative research team involved in this study comprised staff in an early childhood centre, in an infant and a primary school, working collaboratively with three university-based researchers. The 12-month long segment of a longer study employed various data collection methods including video-stimulated review (VSR) to facilitate reflection, critical conversations, classroom observation, interviews and examination of planning documents. The paper illuminates the perspectives and embedded values that the teachers expressed whilst reflecting upon their practice, and highlights common pedagogical themes, including the practice of ‘standing back’, profiling learner agency and creating time and space. Particular strategies were employed by each of the teachers. These approaches appeared to foster possibility thinking in young learners. In addition, the paper considers the development of the teachers’ thinking through the phases of the research process and presents a model for conceptualising a pedagogy of possibility thinking. 相似文献

Blue jays (Cyanocitta cristata) responded to projected black-and-white silhouettes of cherry leaves that were either undamaged or were damaged by either cryptic caterpillars that disguise leaf damage due to their feeding or by noncryptic caterpillars that do not disguise leaf damage due to their feeding. Pecks to the key on which the images were projected were reinforced only if interresponse times fell within specified temporal boundaries. These boundaries were different in the presence of the two types of leaf damage. Following training with one exemplar of each damage type, the jays correctly categorized novel instances of both types. They categorized novel undamaged leaves as if they were examples of leaves showing damage by cryptic caterpillars. Results suggest that the jays can readily discriminate and generalize to new members of a polymorphous stimulus class. The results suggest that techniques for the study of concept formation in animals can be applied to an animal’s ability to categorize stimuli that are involved in a potential prey-predator relationship. 相似文献
