ABSTRACT:  Providing effective food safety education to young consumers is a national health priority to combat the nearly 76 million cases of foodborne illness in the United States annually. With the tremendous pressures on teachers for accountability in core subject areas, the focus of classrooms is on covering concepts that are tested on state performance examinations. As a result, topics such as food safety are rarely addressed in middle school classrooms. Middle school is an ideal time to teach food safety because adolescents are in the process of setting lifelong behaviors; therefore, they are more likely to synthesize new food safety knowledge in a way that will lead to the development of lifelong behaviors. The purpose of this study was to scientifically validate an educational resource that provides a method for classroom teachers to involve young consumers in food safety education while meeting state content area curriculum standards. An interdisciplinary curriculum targeted at middle school students and correlated directly to state content standards was designed to include highly effective instructional strategies that teach food safety concepts through all core subject classes (science, math, social studies, and language arts). The curriculum was pilot tested in 5 schools using a pretest, posttest, and follow-up test assessment model. The results showed that the curriculum was highly effective at raising student knowledge (21% gain) and improving students' food handling behaviors (8.47% gain) from pretests to posttests. In addition, 6 wk after implementation, students retained 86% of their total knowledge gain as measured by a follow-up assessment.  相似文献

In countries around the world policy makers propose that parents should exercise more control over the choice of schools that their children attend. This paper considers the ways in which the introduction of new opportunities for school choice changes the education system. It argues that choice affects the education system as a whole by introducing new actors into the system, by changing the terms of relationships among existing actors, and by creating new pressures within the system that require new responses. The nature, magnitude, and consequences of these effects cannot be predicted in advance, as they depend on a number of factors including the social and economic context. The empirical basis for this paper derives from a case study of the implementation of choice policies in the state of Michigan in the US, but the conceptual issues raised have important implications for the study of school choice wherever such policies are adopted.  相似文献

Standards for College Libraries provide benchmarks for collection size and professional staffing. Formulas from the Standards were used to compare the recommended collection size and number of professional librarians with the actual size of the collections and the number of librarians for a random sample of Baccalaureate I and II colleges.  相似文献

The Principles of Fair Information Practice are almost three decades old and need to be broadened to take account of new technologies for collecting personal information such as drug testing, video cameras, electronic location monitoring, and the Internet. I argue that the ethics of a surveillance activity must be judged according to the means, the context and conditions of data collection, and the uses/goals, and suggest 29 questions related to this. The more one can answer these questions in a way that affirms the underlying principle (or a condition supportive of it), the more ethical the use of a tactic is likely to be. Four conditions are identified that, when breached, are likely to violate an individual's reasonable expectation of privacy. Respect for the dignity of the person is a central factor and emphasis is put on the avoidance of harm, validity, trust, notice, and permission when crossing personal borders.  相似文献
