Understanding the prevalence and demographic correlates of physical activity is important for public health and epidemiological research. This analysis examines the association between acculturation and physical activity in a large (approximately 5,000) sample of Hispanic adults from the 2000 National Health Interview Survey. Scores for eight questions concerning language use were summed to produce an acculturation index. Factor analysis indicated that these questions assessed a single underlying construct. Self-reported adherence to recommendations concerning leisure time physical activity increased from 22. 6% in the least acculturated tertile to 47% in the most acculturated tertile. In contrast, prevalence of walking or bicycling for errands decreased from 25.2 to 18.2%, and prevalence of standing or walking during most of the day decreased from 82.8 to 65.6% as acculturation increased. Thus, patterns of physical activity associated with leisure versus nonleisure time differed among Hispanics with varying acculturation levels. Alternatively, cultural factors may have differential effects on responses to questions concerning leisure and nonleisure time physical activity. In either case, assessing both types of activity is important for monitoring and understanding Hispanic health behaviors and interpreting epidemiological studies that involve physical activity in Hispanics. 相似文献

Previous research suggests that undergraduate research methods students doubt the utility of course content and experience math and research anxiety. Research also suggests involving students in hands-on, applied research activities, although empirical data on the scope and nature of these activities are lacking. This study compared academic performance, research methods anxiety, perceived utility of research methods, and course satisfaction across students in a large lecture-based course and a smaller project-based course. Results show minimal differences in student outcomes between the courses. Limitations are discussed, as is the ideal scope of project-based learning in the undergraduate mass media research methods course. 相似文献

Computerized adaptive testing (CAT) is a testing procedure that adapts an examination to an examinee's ability by administering only items of appropriate difficulty for the examinee. In this study, the authors compared Lord's flexilevel testing procedure (flexilevel CAT) with an item response theory-based CAT using Bayesian estimation of ability (Bayesian CAT). Three flexilevel CATs, which differed in test length (36, 18, and 11 items), and three Bayesian CATs were simulated; the Bayesian CATs differed from one another in the standard error of estimate (SEE) used for terminating the test (0.25, 0.10, and 0.05). Results showed that the flexilevel 36- and 18-item CATs produced ability estimates that may be considered as accurate as those of the Bayesian CAT with SEE = 0.10 and comparable to the Bayesian CAT with SEE = 0.05. The authors discuss the implications for classroom testing and for item response theory-based CAT. 相似文献

Faculty willingness to accommodate students with learning disabilities: a comparison among academic divisions 总被引：1，自引：0，他引：1
One hundred seven faculty members at a northwestern college responded to a questionnaire devised to assess faculty willingness to provide students with learning disabilities instructional, assignment, examination, and special assistance accommodations. Faculty responses to the questionnaire were analyzed to determine if differences existed among faculty in the colleges of Education, Business, and Arts and Sciences. Results indicate that, in general, faculty were willing to provide students with learning disabilities accommodations, but that differences exist among the three academic divisions as to faculty willingness to provide students accommodations. The implications of these results for colleges and universities and future research are discussed. 相似文献

Because toddlers and 2-year-olds learn and explore by using their senses, cooking provides a wealth of multisensory experiences. They can touch, taste, see, smell, and hear food. Cooking can boost children's self-esteem, since it provides children with firsthand experiences, involving them in the processes of planning, preparing, and cleaning. Carefully planned and developmentally appropriate cooking projects can provide young children the opportunity of experiencing the rewards of cooking, such as a sense of accomplishment, joy, and excitement. 相似文献

Abstract Early childhood teachers’ understandings of play were examined in a qualitative comparative study of 41 Japanese and 41 American participants. Qualitative analysis of the data yielded five themes: the power of living, the opportunity to learn and to develop, fun activities, child's work, and the opportunity to explore nature. Two themes emerged in regard to the meaning of play for adults: enjoyable and voluntary activities and child's play. Finally, we identified two themes regarding playfulness: state of heart and fun feelings. Teachers in both nations used rhetoric that is congruent with the current Zeitgeist of developmentally appropriate early education. One theme that differentiated the groups was the notion that play is children's work. While several Americans mentioned this slogan, this was not the case for the Japanese participants. In contrast, the theme of play as the power of living was more representative of Japanese teachers’ understandings of play, and this reflects the philosophy set forth by the Japanese Ministry of Education, Culture, Sports, Science, and Technology. 相似文献

In this paper we present an overview of the advances in debugging standard Prolog programs. The analysis offered is in terms of a classification of tools that provide different degrees of activity in the debugging process. Other possible dimensions of analysis are also outlined. 相似文献

In this study we compared five item selection procedures using three ability estimation methods in the context of a mixed-format adaptive test based on the generalized partial credit model. The item selection procedures used were maximum posterior weighted information, maximum expected information, maximum posterior weighted Kullback-Leibler information, and maximum expected posterior weighted Kullback-Leibler information procedures. The ability estimation methods investigated were maximum likelihood estimation (MLE), weighted likelihood estimation (WLE), and expected a posteriori (EAP). Results suggested that all item selection procedures, regardless of the information functions on which they were based, performed equally well across ability estimation methods. The principal conclusions drawn about the ability estimation methods are that MLE is a practical choice and WLE should be considered when there is a mismatch between pool information and the population ability distribution. EAP can serve as a viable alternative when an appropriate prior ability distribution is specified. Several implications of the findings for applied measurement are discussed. 相似文献
