Family is the central place of socialization during childhood and adolescence. What are the determining factors of family life that are important for the health of children and adolescents and in which stages of their life do these factors take effect? The question is answered with reference to the general health of children and adolescents as rated by their parents. The analysis is conducted with data from the KiGGS study 2003–2006 which is representative of Germany (n?=?17641, age: 0–17 years). The gender-specific effects of different family factors on good health are analysed in five age groups using binary logistic regression analysis including structural, socioeconomic and origin-related factors of family as well as housing conditions and family cohesion. Bivariate analysis indicates significant effects on general health for almost all included factors (at least in some age groups). Multivariate analysis shows family cohesion to be the most important factor for good health. In boys a bilateral migration background also has an adverse effect on good general health until the beginning of adolescence.  相似文献

The following article gives an overview on the research on teaching effectiveness and teaching quality. It starts with a glance back to the early programmatic demands formulated in the 1970s concerning teaching in higher education and sketches the development towards the current research strands. A special focus will be given to theoretical and methodological aspects of researching quality of teaching in higher education. We then will draw upon examples of state-of-the-art research in the respective construct. These examples can be clustered into (a) evaluation of teaching quality and measurement of key competency acquisition, (b) research on the efficacy of inquiry-based vs. lecture-based teaching and (c) action research into teaching and learning in higher education  相似文献

This paper interprets Wilhelm von Humboldt??s travelogue of his voyage to the Basque country (??Die Vasken??) as an empirical study on human development (??Bildung??) that applies an ethnographic research approach. Against the background of Humboldt??s comparative anthropological considerations the paper focuses on the underlying theory and methodology as well as on the results in Humboldt??s study of the Basques. It will be shown that in ??Die Vasken?? Humboldt directs his attention at anthropological questions on character building (??Charakterbildung??) through applying his anthropological method which combines empirical research with philosophical speculation. The analysis of the results of Humboldt??s study of the Basques demonstrates that Humboldt succeeds in developing his anthropological theory of ??Bildung?? in such a way that he can apply his new insights later in practice in the reform of the Prussian educational system. Finally, a critical reflection about the results of ??Die Vasken?? points out a central methodological and at the same time educational problem in ethnographic research on ??Bildung??. With this interpretation of Humboldt??s study of the Basques the paper provides a historical reflection about theory and methodology in educational anthropology that offers still important insights for actual ethnographic research in the field of education.  相似文献

Drawing from a domain specificity perspective, we assert that maternal sensitivity to infant distress cues is distinct from maternal sensitivity to non-distress cues. We review evidence from prior research demonstrating that the two constructs have more unshared than shared variance and that sensitivity to infant distress is a unique predictor of infants' early emotional well-being when both types of sensitivity are examined as simultaneous predictors. In addition, we present new evidence to test the hypothesis that maternal sensitivity to infant distress and non-distress have different origins. We draw on data from a subset of mothers and infants who participated in Phase I of the NICHD Study of Early Child Care (Study 1) and from 101 mother-infant dyads who participated in a longitudinal study of the origins of maternal sensitivity (Study 2). In both studies, maternal sensitivity to distress and non-distress were rated when infants were 6 months old. In both studies, socio-demographic risk (i.e., young, unmarried, low income mothers) was a stronger predictor of sensitivity to non-distress than of sensitivity to distress. In Study 2, mothers' emotional and cognitive responses to videotapes of crying infants during the prenatal period predicted maternal sensitivity during tasks designed to elicit infant fear and frustration but were unrelated to maternal sensitivity in a non-arousing free play context. Maternal sensitivity during infancy can be further divided into specific sub-types that have unique origins and unique effects on subsequent child well-being. Methodological, theoretical, and applied implications of such an approach are discussed.  相似文献

A content analysis of 11 journals that published career, vocational, and work-related articles from 1990 to 2009 was conducted. Of 3,279 articles analyzed, 55.9% used quantitative methods and 35.5% were theoretical/conceptual articles. Only 6.3% used qualitative research methods. Among the qualitative empirical studies, standards of academic rigor and procedures that are typically honored within qualitative research were either not followed or were not reported. Fundamental changes need to occur if qualitative research methods are to rise to a higher level of publication and general interest among consumers of career development literature. Recommendations for future training and research are provided.  相似文献

The present study examined the development of morphological awareness and its contribution to vocabulary and reading comprehension among young Chinese-speaking English language learners (ELLs). We focused on two aspects of morphological awareness: derivational awareness and compound awareness. Participants included 46 kindergarteners (younger cohort) and 34 first graders (older cohort) of Chinese descent in Canada at the beginning of the study. Children were administered a battery of English measures including derivational awareness, compound awareness, phonological awareness, receptive vocabulary, and reading comprehension at two time points spaced 1?year apart. Results demonstrated a steady growth in Chinese-speaking ELL children??s derivational and compound awareness from kindergarten to Grade 2. Importantly, for the first graders, morphological awareness accounted for unique variance in vocabulary concurrently, and unique variance in both vocabulary and reading comprehension a year later. Generally speaking, the variance explained by morphological awareness increased with grade level, and derivational awareness accounted for more variance in vocabulary and reading comprehension than did compound awareness. These results underscore the emerging importance of morphological awareness, especially derivational awareness, in young Chinese-speaking ELL children??s English reading development.  相似文献

Abstract

The efficiency of two practice schedules was examined on two large muscle motor tasks. There were four groups of subjects (N = 160); each individual in a group performed on one of the two motor tasks under one of the two conditions. Distributed practice consisted of alternating 30-second trials of practice and rest; massed practice was continuous for 8 minutes. Comparisons made during the last minute of practice prior to the rest pause revealed that the massed groups had significant decrements in performance level. In contrast, after the rest period, when both groups were on a distributed schedule, no difference was found in the amount of learning. Learning was found to be a function of the number of trials and independent of the conditions of practice.  相似文献
