In discussion of the properties of criterion-referenced tests, it is often assumed that traditional reliability indices, particularly those based on internal consistency, are not relevant. However, if the measurement errors involved in using an individual's observed score on a criterion-referenced test to estimate his or her universe scores on a domain of items are compared to errors of an a priori procedure that assigns the same universe score (the mean observed test score) to all persons, the test-based procedure is found to improve the accuracy of universe score estimates only if the test reliability is above 0.5. This suggests that criterion-referenced tests with low reliabilities generally will have limited use in estimating universe scores on domains of items.  相似文献

Mothers' perspectives of children's peer-related social development were obtained from matched groups of young children with developmental delays, communicative disorders, and typically developing children. Structured interviews elicited information on numerous issues including mothers' views of the importance of children's social skills development, rationales with respect to why children succeed or had difficulties on specific social tasks, and the socialization strategies mothers employ to promote children's peer-related social development. Mothers also reported on their efforts to arrange play with peers for their child and the degree to which they monitored that play. Results indicated that mothers rated children's social development as highly important, offered primarily internal rationales (e.g., traits, dispositions) for success or difficulties in achieving social tasks, and endorsed moderate and low power socialization strategies. Differences across the three groups were minimal. Mothers arranged play with peers least often for children with developmental delays and communication disorders, but monitored play more extensively for children with delays. These finding were discussed in terms of mothers adopting a developmental orientation to understand children's social development and their implications for maternal participation in peer competence intervention programs.  相似文献

Recent research on student learning in higher education has identified clear associations between variations in students’ perceptions of the academic environment and variations in their study behaviour. This study investigated a general theoretical model linking students’ demographic characteristics, perceptions and study behaviour with measures of outcome, and in particular, compared three accounts of the causal relationship between perceptions and study behaviour. Data were obtained from 469 postgraduate students at six British business schools. Path analysis was used to assess the causal relationships among the students’ age and gender, their scores on the Course Experience Questionnaire, their scores on the Revised Approaches to Studying Inventory and their ratings of general satisfaction with their programmes. This yielded evidence for the causal efficacy of most of the paths identified in the general theoretical model. In particular, as in the case of students taking more traditional academic subjects, there exists a bidirectional causal relationship between variations in students’ perceptions of the academic environment and variations in their study behaviour.  相似文献

Faced with repression and reform, humor has become tactical for public school teachers in Oaxaca, Mexico, engaged in a decades-old movement that after 2006 involved intensified street- and school-based pedagogies. This piece explores how humor adds to a political project via mocking names, images, and dictates of elite leaders to bring a here and now to what is taken as inaccessible in the teachers’ political lives. Humor forms part of an (e)sc(h)atology in which critical practices are part eschatological, a call for definite transformation, and part scatological, embodied vulgarity. La parte chusca (the funny part), its (e)sc(h)atological contribution, angles toward critical literacies in Oaxaca and beyond.  相似文献

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
