ABSTRACT:  Musical parodies of contemporary songs with their lyrics altered to address current food safety issues were incorporated into a variety of food safety educational programs and the effectiveness of the music was evaluated by semiquantitative and qualitative measures. Audiences receiving the music-enriched curricula included school foodservice supervisors, school foodservice managers, culinary arts instructors, culinary arts students, Family and Consumer Sciences teachers, and youth aged 8 to 12 y and studies were conducted in South Carolina, North Carolina, and Delaware. Among school foodservice supervisors, school foodservice managers, and culinary arts students, most participants were able to recall the main points of each song that was introduced in the curriculum. The culinary arts students were less likely to recall the main points of each song than were the other 2 groups, possibly because of the lack of prior knowledge of food safety practices as well as a lack of preference for the style of songs used. Family and Consumer Sciences teachers were enthusiastic about the use of the music but also identified potential barriers to the successful use of the music, due to the potential lack of appropriate audiovisual equipment, a lack of skills in using such equipment, and time constraints for the use of music in curricula due to the strong emphasis on end of year testing. Participants in the summer youth groups demonstrated significant increases between pre- and posttest examinations of safe food handling behaviors and most were able to quote lines or phrases from the songs.  相似文献

I begin by stating a small set of troublesome but pervasive educational issues. While these have remained in the background during our work, they have served as the impetus for developing and reflecting on possible roles for computer technology in classrooms. In the remaining sections of the paper I propose that the computer can serve as an effective mediator between action and symbol. After setting the scene in the Laboratory for Making Things, I give an extended example of how computer-as-mediator contributes to learning when played out in this rather unusual classroom.  相似文献

During a dual-center study on obese and normal weight children and adolescents, focusing on glucose metabolism, we observed a marked difference in glucose results (N = 16,840) between the two sites, Salzburg, Austria and Uppsala, Sweden (P < 0.001). After excluding differences in patient characteristics between the two populations as cause of this finding, we investigated other preanalytic influences. Finally, only the tubes used for blood collection at the two sites were left to evaluate. While the Vacuette FC-Mix tube (Greiner Bio-One, Kremsmünster, Austria) was used in Uppsala, in Salzburg blood collections were performed with a lithium heparin tube (LH-Monovette, Sarstedt, Germany). To prove our hypothesis, we collected two blood samples in either of these tubes from 51 children (Salzburg N = 27, Uppsala N = 24) and compared the measured glucose results. Indeed, we found the suspected bias and calculated a correction formula, which significantly diminished the differences of glucose results between the two sites (P = 0.023). Our finding is in line with those of other studies and although this issue should be widely known, we feel that it is widely neglected, especially when comparing glucose concentrations across Europe, using large databases without any information on preanalytic sample handling.  相似文献

Century 21 International, like so many sales organizations, suffered lower productivity and higher attrition from new sales associates than they judged to be acceptable. The answer, Century 21 executives believed, was to develop a twenty-one module, multimedia training program. An external consultant urged them to study the situation prior to committing to any one solution. The results were clear. While new sales people certainly needed to have their field skills “buffed” after going through pre-licensing training and entering the office, that was not their most critical need. Far more important was an in-office support system, someone to tell them how to think through inevitable rejections, how to approach recurring challenges, how to maintain confidence even when sales do not occur, how to prospect portions of the community and how to integrate into the real estate community. The data revealed the need for a solution system comprised of training, incentives, performance support materials, the introduction of a new position, a coach, into each office, and a selection method for that coach. This article describes the front end study, the program, and some of its results in real estate offices across the United States.  相似文献

The effects of neighborhood and family income and family risk factors on developmental test scores at ages 1 through 3 are examined using a subsample (N = 347) from the Infant Health and Development Program. Beneficial effects of low numbers of risks were found for scores at ages 1 through 3. Family poverty was associated with lower scores at ages 2 and 3. Neighborhood affluence was associated with higher scores at age 3. The family risks-test score association at ages 1 through 3 and family income-test score association at ages 2 and 3 were mediated by home environment. Mediated effects were stronger for family income-test score associations at age 3 than for neighborhood income. Moderating effects of family risk on family and neighborhood income effects revealed an interaction between family poverty and risks for scores at age 3. Explanations for the early links between family risks and test scores and the later links between income and test scores are discussed.  相似文献

Although many immigrant children to the United States arrive with their parents, a notable proportion are first separated and later reunited with their parents. How do the experiences of separation and reunification shape the well-being of immigrant children? Data were from a national survey of legal adult immigrants and their families, the New Immigrant Survey from 2003 to 2004 (for academic achievement, age 6–12, N = 876; for psychosocial well-being, age 6–17, N = 1,084). Results indicated that immigrant children who were once separated from their parents exhibited poorer literacy and higher risk of emotional and behavioral problems than those who migrated with parents. A protracted period of separation and previous undocumented status of parents amplified the disadvantages experienced by these children.  相似文献
