This paper presents the initial findings of a long-term study to examine whether the introduction of compulsory school science for pupils in UK schools in 1991 is effective in raising the general level of scientific literacy. The use of the term 'scientific literacy' in the literature is considered and a definition of the term as it is applied in this study is offered. The scientific literacy level of two groups of initial teacher training studentswith contrasting experiences of school sciencewas compared. Students completed a simple science test that had been originally written for 11-year-old children. The average test score of students who had experienced compulsory school science from the ages of 11 to 16 was found to be significantly higher (p = 0.014) than that of students for whom school science was optional at secondary level. The study also highlights specific areas of conceptual difficulty in basic science experienced by almost all of the students tested. Test questions relating to the circulatory system, light and sound produced very low scores from almost all students, regardless of their science background. The paper considers the implications of these findings for science teachers and policymakers in both the primary and secondary sectors.  相似文献

Background This paper compares the findings from a recent, large-scale UK-wide survey of primary teachers' confidence in teaching science with the results of a seminal report carried out 10 years ago by Wynne Harlen in Scotland. Recent reports from across the UK have indicated there are still serious concerns relating to primary teachers' confidence and ability to teach science effectively.

Purpose The main research aims were to provide a clear, evidence-based analysis of the current issues facing primary science in the UK; explore primary teachers' confidence in science teaching and to evaluate the impact of science initiatives taking place in UK primary schools.

Sample The sample for the study comprised: telephone interviews with 300 primary teachers from all UK regions; seven focus groups of primary teachers held in England, Northern Ireland, Scotland and Wales to further explore the issues raised in the telephone interviews; and workshops from a two-day conference of 75 stakeholders in primary science from all UK regions (approximately half the delegates were teachers; also represented were teacher educators (initial and continuing professional development), curriculum developers and policy-makers). In addition, 100 teacher education institutions were surveyed in relation to their participation in primary science initiatives.

Design and methods The methodology for both studies comprised qualitative and quantitative elements (see sample details, above). All data were collected between June and September 2004.

Results The findings indicated that there are improvements in some areas of primary teachers' confidence in teaching science. However, the study showed that half of the teachers surveyed cited lack of teacher confidence and ability to teach science as the current issue of major concern in primary science. This paper also reports on some of the professional development initiatives carried out by higher education institutions in primary science.

Conclusions The paper concludes that there has been some progress in developing teacher confidence in primary science over the past 10 years. However, the situation is still critical for all stakeholders. Half of the teachers surveyed in the UK for the present study identified lack of teacher confidence and ability to teach science as the major issue of concern in primary science. Higher education institutions need to enhance the preparation of new primary teachers to ensure that they are all confident and effective teachers of science. They could also increase their partnership work with schools and other continuing professional development (CPD) providers in relation to primary science. The evidence demonstrates clearly that there is a need for substantially increasing science professional development for primary teachers. It also shows that such professional development could be more effectively targeted at specific aspects of science teaching that are more challenging for teachers. Further, the study shows that professional development in science works, in that teachers who have experienced science continuing professional development (CPD) are much more confident to teach science than those who have not.  相似文献

Can research on disciplinary socialization and imprinting help us understand the extent to which educational developers bring aspects of their disciplinary training to their educational development research? In this paper, we explore the relationship between the research approaches developers associate with their original disciplinary training and those they actively use in their own educational development research, comparing and contrasting the strength of imprinting by discipline cluster. We discuss implications for how educational development as a field supports new developers moving into the field from another discipline and for how developers work with academic colleagues in other disciplines.  相似文献

The belief that parent involvement is an important aspect of early intervention programs for children with disabilities is widely accepted, but the empirical evidence to support this belief is limited (White, Taylor, & Moss, 1992). Using a randomized experimental design, the present study compared a classroom-based early intervention program with the same program supplemented by a parent involvement component. The parent involvement component consisted of weekly parent meetings focused on (a) training parents to provide additional intervention, (b) providing information on general topics, and (c) providing social support. Outcome data were obtained following intervention and longitudinally on child and family functioning, and on educational outcomes. A cost-effectiveness analysis was completed. With respect to measures of child development and family functioning, there were some small initial effects in favor of the parent involvement group that tended to fade out in later reassessments. However, longitudinal educational outcomes indicate positive effects on child placements and teacher perceptions of the children's functioning in favor of the parent involvement group. The parent involvement component was not immediately cost effective, but may be in the long term.  相似文献

Control exerted by different categories of spatial information on short-distance return to shelter by young cockroach larvae and weighting of different information sources in conflict situations were investigated. In the absence of landmark cues, larvae preferred information given by path integration with kinesthetic cues over scototactic cues. When two landmark cues with a particular angular position between them were shifted 180°, larvae relied on these learned landmarks provided that their relative angular position was kept unchanged. When only one of the landmark cues was shifted 180°, larvae preferred to use the path integration system. When larvae could not use path integration cues, a modified configuration of the landmarks disturbed them. They relied on scototactic cues, although some seemed to rely on either one of the landmarks to find their shelter. Cockroaches could change the order of importance that they normally attributed to certain classes of spatial information (in increasing order: scototaxis, path integration, and learned visual landmarks) in relation to ongoing conditions.  相似文献

The authors describe an innovative practice in classroom pedagogy for teaching counseling theories. In an attempt to make the counseling process “transparent” for students, instructors demonstrated clinical thinking using monologue and dialogue during role plays conducted in class. Support for this approach is offered, and feedback from students in the course is presented.  相似文献

The Drug Information Portal is a free Web resource from the National Library of Medicine (NLM) that provides a user-friendly gateway to current information for more than 15,000 drugs. The site guides users to related resources of NLM, the National Institutes of Health (NIH), and other government agencies. Current drug-related information regarding consumer health, clinical trials, AIDS, MeSH pharmacological actions, MEDLINE/PubMed biomedical literature, and physical properties and structure is easily retrieved by searching on a drug name. A varied selection of focused topics in medicine and drugs is also available from displayed subject headings. This column provides background information about the Drug Information Portal, as well as search basics.  相似文献
