ABSTRACT:  The purpose of this study was to use a validated instrument to determine the attitudes and knowledge of high school teachers regarding food irradiation, and to determine the correlations among their knowledge and attitudes and certain demographic variables. Knowledge and attitudes about food irradiation were measured in selected high school family and consumer sciences teachers ( n = 121) who taught Food and Nutrition, Food Science and Technology, and/or Food Production Management and Services, via a 24-item instrument with 6 factors. Results revealed these teachers held neutral to positive attitudes about the safety of irradiated foods, their perception of the risk of foodborne illness, and learning about food irradiation, and neutral to negative perceptions of their understanding of food irradiation and their competence to teach about it. These teachers had a moderate knowledge base regarding food irradiation. Teachers' attitudes regarding the safety of food irradiation were positively correlated with their perceived understanding of food irradiation, actual knowledge of it, and competence to teach about it. Their perceived understanding of food irradiation was positively correlated with competence to teach about it, knowledge, and attitudes toward the safety of food irradiation. The only demographic variable correlated with knowledge or attitudes was teachers' previous food irradiation educational experiences. These data suggest the importance of education for family and consumer sciences teachers concerning food irradiation.  相似文献

With particular reference to recent developments (including some in communication‐technology), this first of two papers explores the nature of ‘language change’ – its kinds, mechanisms and effects – and some attitudes towards it. It then suggests a case for teaching and learning about language change (bearing in mind, particularly, students in the 11–16 age range). The second paper, which will appear in Changing English 18:2, suggests approaches of two broad kinds and contexts: (1) as opportunities arise in undertaking other work; and (2) within planned, ‘set‐piece’ activities. Extensive notes/references are offered as support to teachers.  相似文献

反向旅游是一种追求"景观差异极大化"的旅游形式,反向旅游市场是一个极具潜力的市场。按照"极大化差异景观"的产生原因,可以将反向旅游分为自然型反向旅游、人文型反向旅游和综合型反向旅游。旅游者的反向旅游意向是既已存在且比较强烈的,通过对相应的营销策略的研究,可以起到既能满足旅游者需求,又能实现营销目标的作用。在对反向旅游进行类型划分的基础上,以对北京市民调查结果为依据,结合反向旅游理论和旅游者心理特征,运用经典的4P营销组合理论,从产品策略、价格策略、销售渠道策略和促销策略四个方面提出反向旅游营销策略。  相似文献

The purpose of this investigation was to determine the extent to which pre-service educators’ interpersonal characteristics affected their attitudes toward teaching students with disabilities (inclusion), as measured by the FIRO-B and ATIES pre- and post-course. The FIRO-B was administered to assess expressed and wanted aspects of three interpersonal needs: personal inclusion, affection and control. The ATIES was administered to measure attitudes toward classroom inclusion of students with physical, academic, behavioral and social disabilities. Repeated measures ANOVAs revealed a main effect for wanted inclusion and an interaction effect for expressed inclusion and expressed affection on attitudes toward classroom inclusion. Ultimately, these findings reveal how unique relational characteristics may influence preparation initiatives and may encourage consideration of how individual factors may mediate teacher training and preparation.  相似文献

某桥墩桩基偏位分析与纠偏实施效果   总被引:3,自引:0,他引:3  
根据桥墩桩基施工现场的具体情况,通过理论计算,分析了两基桩产生偏位的主要原因。采用卸载止推、反向堆载、挖坑卸荷、强力牵拉等综合纠偏方法对产生偏位的两基桩实施纠偏,经过一个多月的缓慢纠偏使两桩基基本恢复原位,纠偏后经桩身低应变动测(反射波法)检测其桩身完整满足设计要求。  相似文献

Abstract

University rankings are increasingly important internationally, and in the UK include a sustainability ‘Green League’. However, there is little evidence about experiences of studying in ‘sustainable universities’. We report an empirical study at five universities in varied positions in the Green League, exploring students’ energy literacy, environmental attitudes and perceptions of their institution’s energy-saving efforts. Although the link to energy literacy is not clear, findings suggest that there are significant differences between students’ environmental attitudes at universities placed at different points in the league. In addition, students at higher ranked universities are more positive about their university’s energy-saving efforts, suggesting that these institutions may exhibit more overt manifestations of sustainability. This is important since students report being more likely to choose energy-conservation behaviours if there is visible representation of energy use. The study is the first to attempt a comparison between universities at different positions in a sustainability ranking.  相似文献

The literature on teacher uncertainty suggests that it is a significant and perhaps inherent feature of teaching. Yet there is disagreement about the effects of these uncertainties on teachers as well as about the ways that teachers should regard them. Recognition of uncertainties can be viewed alternatively as a liability or an asset to effective teaching. Findings from the literature on uncertainties in teaching are summarized and analyzed, including explanations in the research about what accounts for and contributes to uncertainties. Recommendations for research and professional development are provided.  相似文献

This study investigated the chemistry laboratory classroom environment, teacher–student interactions and student attitudes towards chemistry among 497 gifted and non-gifted secondary-school students in Singapore. The data were collected using the 35-item Chemistry Laboratory Environment Inventory (CLEI), the 48-item Questionnaire on Teacher Interaction (QTI) and the 30-item Questionnaire on Chemistry-Related Attitudes (QOCRA). Results supported the validity and reliability of the CLEI and QTI for this sample. Stream (gifted versus non-gifted) and gender differences were found in actual and preferred chemistry laboratory classroom environments and teacher–student interactions. Some statistically significant associations of modest magnitude were found between students' attitudes towards chemistry and both the laboratory classroom environment and the interpersonal behaviour of chemistry teachers. Suggestions for improving chemistry laboratory classroom environments and the teacher–student interactions for gifted students are provided.  相似文献
