This paper explores children's beliefs about global warming and energy sources from a psychological perspective, focusing upon situational influences upon subjective beliefs, including perceived self‐efficacy. The context of the research is one of growing concern at the potential impacts of global warming, yet demonstrably low levels of self‐efficacy amongst both adults and children to effectively respond to this large‐scale environmental problem. Empirical research was conducted on a sample of 198 UK children and adults to explore the influence of a cooperative learning environment upon children's beliefs about global warming and energy. A comparative design was adopted, contrasting 9–12 year old members of the Woodcraft Folk educational organisation with non‐members of similar age and with adult members of the same organisation. Results indicate that cooperative learning environments can have a significant and positive effect upon children's beliefs about large‐scale environmental problems. In particular, Woodcraft folk children reported significantly higher levels of personal awareness and perceived self‐efficacy in relation to global warming in comparison to their peers. Secondly, unexpected differences were identified between levels of perceived self‐efficacy in children and adult Woodcraft folk. The implications of these differences for the design of educational programmes seeking to empower children to respond to global warming are discussed.  相似文献

This study sought to demonstrate that many aspects of preschoolers' peer conflict behavior are sensitive to the subtle change in social situation that occurs when a child plays with a different partner. Twenty-seven pairs of preschoolers were videotaped over four 15-minute play sessions; in the fourth session, half of the pairs played with a different partner, while half were with the same partner. Frequency and theme of conflicts, strategies used, frequency of yielding to partner, and percentage of conflicts solved were observed. Initiating and negotiating behavior in early sessions better predicted behavior in the fourth session for the same-partner (vs. change-partner) group, and thus emerged as behaviors sensitive to social context changes. Results indicate that preschoolers have a remarkably varied array of conflict behaviors and that much of their conflict behavior is sensitive to influences inherent to social interaction with a specific partner. Ways in which the apparent sophistication in young children's social understanding can inform developmental approaches to early childhood education as well as both preventative and therapeutic conflict resolution programs are discussed.  相似文献

The teaching of the science topic sound, a popular topic in science instruction, is selectively analyzed over the past century using evidence excerpted from a prominent teacher practitioner journal (School Science And Mathematics). Shifting innovative recommendations on how teachers of science should teach the sound topic are identified in the categories of content and pedagogy. Historical connections to the scientific development of sound, identification of what constitutes the subject matter of sound, recommended general pedagogical strategies, and best practices for teaching strategies associated with the sound concept are examined. Discussion relates to the influence of contextual factors in a given time period (social and theoretical) on the design of curriculum materials used to guide instructional practice. One implication for science teacher education is the need for science teachers to develop an historically and philosophically grounded perspective by examining both the teaching practices on a science topic over an extended time and the historical scientific development of the science topic.  相似文献

Animating the graphics in electronic documents may increase readers’ willingness to study them but may impair or distort the processes of gist comprehension. Experiment 1 confirmed that, compared with static diagrams, animation increased readers willingness to study a range of graphic genres (maps, time-lines, drawings of unfamiliar objects). Total reading time was also increased but readers’ differential access of static and animated graphics confounded the interpretation of immediate and delayed retention tests. Experiment 2 contrasted the effects of accessing the graphics before or during reading. Scores on a quiz immediately after reading were significantly higher when the graphics were seen before rather than during reading, suggesting that readers found it difficult to integrate the graphics while still building the gist of the text. Scores on both an immediate and a delayed quiz were significantly higher when the graphics were static rather than animated. One pointer to the cause of the decrement with animated graphics was that the quiz performance of readers having animated graphics correlated with their scores on a picture memory test, whereas those of readers with static graphics did not. In contrast the delayed quiz scores of readers with static graphics showed a significant interaction with their performance on a digit memory task. Readers with high scores on digit memory benefited from accessing the graphics while reading, but readers with low scores on the digit test were impaired by such access during reading. This suggests that the cognitive skills needed for integrating text with animated graphics may differ from those needed for dealing with static graphics.  相似文献

Journal coverage is one factor that affects the retrieval of relevant information from bibliographic databases. The aims of this study were to investigate the coverage of databases for psychiatry journals, and to assess the overlap between databases. Psychiatry journals were identified using Ulrich’s International Periodicals Directory and then analysed to see which bibliographic databases indexed the most journals. A total of 213 abstracting and indexing services were listed as indexing at least one of the 977 psychiatry journals identified. The four most frequently cited databases (PsycLIT, EMBASE, BIOSIS and MEDLINE) indexed 506 (52%) of the psychiatry journals. Of these 506 journals, PsycLIT indexed 367 (73%), EMBASE 337 (67%), BIOSIS 243 (48%) and MEDLINE 236 (47%). Combining the databases with the highest yields (PsycLIT and EMBASE) increased the number of journals indexed to 461 (91%). The four databases combined accounted for 90% of all psychiatry journals found to be indexed by at least one abstracting and indexing service. More than 400 journals were not indexed at all. Variations in the overlap between PsycLIT, EMBASE, BIOSIS and MEDLINE, and the high proportion (35%) of journals indexed in only one of these four databases emphasize the importance of searching more than one or even two databases to ensure optimal coverage of the literature.  相似文献

Does studying about the nature(s) of science contribute to a prospective teachers' effectiveness as a science teacher? This research grew out of a course created by a science educator and historian of science who believed prospective teachers needed more complex understandings of the cultural wars surrounding science. The research team consisted of five prospective teachers who participated in the course as well as the two instructors. This paper describes the experience of participating in the course from both perspectives. We argue that studying the cultural wars over science contributes to prospective teachers' professional growth as much because the course elicits tacit beliefs about school science as it introduces more complex understandings of science. We found that prospective teachers' tacit beliefs about school science were their greatest barrier to developing more complex understandings about the nature(s) of science. We contend that willingness to grapple with complexity and developing a professional identity by locating oneself in the conversations about the nature(s) of science are better criteria for determining the professional growth of prospective teachers than knowledge measures. Finally, we argue that prospective teachers should be viewed as professionals who are responsible for finding their own voice, making their own decisions, and considering the consequences of their beliefs on their practice. This study raises questions critical to teacher education programs for prospective teachers and teacher‐educators alike. © 2000 John Wiley & Sons, Inc. J Res Sci Teach 37: 895–915, 2000  相似文献
