The English translation of Pierre Pomet's A Compleat History of Druggs (1712) demonstrates how the expansion of print culture altered the way that scientific ideas were communicated. Although it makes utilitarian claims, the text of the History departs from the style of contemporary British pharmacopoeias by emphasizing the exotic aspects of drugs. In this sense, the text exemplifies how Enlightenment science could be sold to a cross-over audience interested as much in the fantastical as in the quality and operation of drugs.  相似文献

This study focused on past excellent teachers’ classroom management strategies from the perspective of 148 pre-service teachers. The purpose of the study was to examine how pre-service teachers’ memories reflect classroom management models that are typically taught in teacher education coursework prior to their study of those models, as well as to explore memories that did not fit a particular model. Results indicated that pre-service teachers related episodes that clustered on establishing rules, but were less likely to relate experiences based on other strategies such as withitness, smooth transitions, or formal classroom meetings. Implications for teacher education are explored.  相似文献

This study examines whether levels of father engagement (e.g., verbal stimulation, caregiving, and physical play) vary by race/ethnicity using a model that controls for fathers' human capital, mental health, and family relationships. It also tests whether the models work similarly across race/ethnic groups. Its sample of N=5,089 infants and their families is drawn from the Early Childhood Longitudinal Study - Birth Cohort (ECLS-B). We found that, after including controls, African American and Latino fathers had higher levels of engagement in caregiving and physical play activities than White fathers. There were no differences in verbal stimulation activities across race/ethnicity. Fathers' education (college level) predicted more verbally stimulating activities whereas fathers' report of couple conflict predicted less caregiving and physical play. Although levels of engagement differed across the groups, the overall models did not differ by race/ethnicity, except for physical play. African American mothers who reported high levels of depressive symptoms had partners who engaged in more physical play than White mothers with high levels of depressive symptoms.  相似文献

Many studies have examined associations between children's theory of mind and social behavior with familiar peers, but to date none have examined how theory of mind might relate to behavior toward unfamiliar peers in a play setting. Forty-four 4-year-olds (21 girls, 23 boys) participated in standard theory-of-mind tasks and in a play session with 3 or 4 other children who were unfamiliar. Children were also tested on general vocabulary ability. No relations were found between theory of mind and social engagement. However, positive associations were found between theory of mind and time spent observing, but not interacting with, other children. Possible explanations of the links between theory of mind, temperament, and social interest are considered.  相似文献

Research on the relation between students’ achievement (ACH) and their academic self-concept (ASC) has consistently shown a Big-Fish-Little-Pond-Effect (BFLPE); ASC is positively affected by individual ACH, but negatively affected by school-average ACH. Surprisingly, however, there are few good UK studies of the BFLPE and few anywhere in the world based on science self-concept (S-ASC). Addressing this substantive limitation in existing research with data from PISA 2006, we extend new multigroup doubly-latent multilevel structural equation models – a substantive-methodological synergy. BFLPE predictions for S-ASC are supported for: the total international sample; the total UK sample; each of the four UK countries considered separately. The BFLPE was marginally larger in the UK than the international sample. However, consistent with the selective nature of school systems in the UK, the BFLPE was larger in Northern Ireland and, to a lesser extent, England than in Scotland or Wales.  相似文献

Recently, European school systems have seen various attempts to ‘modernise’ their governance. Market and competition oriented reforms have not been central to governance innovation strategies in German speaking countries, however, their number and relevance is rising in recent years. A free school choice policy which abolishes “school districts” which legally define fixed school catchment areas was introduced in the school year of 2007/2008 in the Austrian city of Linz.The effects of the implementation of this policy on the primary school sector were studied by a standardised questionnaire administered to a representative sample of 3425 parents of five age groups of primary school children. The return rate was about 55%. By special measures during data collection a satisfactory representation of parents with migrant background was achieved.Three questions are discussed in the paper: (1) Is there a rise in segregation in schools as a result of free choice policy? (2) Is there a change in the composition of the student population in different schools as a result of free choice policy? (3) Is there a change in parent school choice behaviour of as a result of free choice policy?Our data indicates that segregation in primary schools with respect to ethnic and social family characteristics increases after the policy implementation, but the sample size is too small to find significant results. In addition, no significant change is observed in the social composition of schools. In accordance with the previous findings no significant modifications of choice behaviour occur for different ethnic or social groups after free choice. However changes in choice motives can be observed.  相似文献
