In this article, the theoretical framework of developmental pedagogy is presented as a tool in studying and developing children’s knowing within the arts. The domains of art focused on are music, poetry and dance/aesthetic movement. Through empirical examples from a large‐scale research project, we illustrate the tools of developmental pedagogy and show how this perspective contributes to our understanding of children’s learning of music, dance and poetry. More specifically, we will analyse: (a) the important role of the teacher in children’s learning within the arts; (b) the importance of conversing when learning the arts; (c) what constitutes the knowledge, what we refer to as ‘learning objects’, to be appropriated within the three domains of art focused on; and (d) how to conceive of progression in children’s knowing within the arts. 相似文献

This study was designed to investigate the cross‐cultural similarity of vocational interests as measured by the Strong Interest Inventory. An Icelandic version of the SII was administered to Icelandic college students studying medicine, business, library science, geology, biology, psychology, theology, and nursing. 290 first year students were tested, and 123 students approaching final exams of whom 80 were re‐tested two years later. Reliability coefficients for the scales (occupational themes, interests, occupations and the special scales) varied from 0.79 to 0.89. On the basis of the US norms 74‐83 percent of students were correctly classified into their actual professional group. The results indicate that US norms are valid for Icelandic college students and allow for satisfying prediction of educational and vocational choice. This may indicate that the US norms of the SII could be applicable for other Nordic college students. SII scale scores for all groups indicate identical interest structure for Icelandic and US groups of the same field of study. 相似文献

Summaries English This paper presents the results of a study of the development of pupils’ knowledge of the process of photosynthesis and the related biological processes of respiration, breathing and digestion. The information already known to primary pupils untutored in biology was assessed and the changes effected by teaching were monitored in the secondary school. The results indicate that concepts which are wrong but which are nevertheless meaningful to the learner may escape detection by the usual methods of testing and are highly resistant to replacement by correct information. The formation of wrong concepts may predate formal instruction or may arise during the course of instruction as a result of the inappropriate use of subsuming information. 相似文献

Forms of knowledge and modes of innovation 总被引：5，自引：0，他引：5
This paper contrasts two modes of innovation. One, the Science, Technology and Innovation (STI) mode, is based on the production and use of codified scientific and technical knowledge. The other, the Doing, Using and Interacting (DUI) mode, relies on informal processes of learning and experience-based know-how. Drawing on the results of the 2001 Danish DISKO Survey, latent class analysis is used to identify groups of firms that practice the two modes with different intensities. Logit regression analysis is used to show that firms combining the two modes are more likely to innovate new products or services than those relying primarily on one mode or the other. The paper concludes by considering the implications for benchmarking innovation systems and for innovation policy. 相似文献

That technological developments are strongly influenced by economic, political, and social factors is now widely recognised. The interplay of these factors is well exemplified by Sweden's system of storing strategic reserves of oil underground in huge caverns blasted from solid rock. With the completion of present plans total capacity of peace-time reserves will exceed ten million cubic metres. 相似文献

AbstractFactor mixture models are designed for the analysis of multivariate data obtained from a population consisting of distinct latent classes. A common factor model is assumed to hold within each of the latent classes. Factor mixture modeling involves obtaining estimates of the model parameters, and may also be used to assign subjects to their most likely latent class. This simulation study investigates aspects of model performance such as parameter coverage and correct class membership assignment and focuses on covariate effects, model size, and class-specific versus class-invariant parameters. When fitting true models, parameter coverage is good for most parameters even for the smallest class separation investigated in this study (0.5 SD between 2 classes). The same holds for convergence rates. Correct class assignment is unsatisfactory for the small class separation without covariates, but improves dramatically with increasing separation, covariate effects, or both. Model performance is not influenced by the differences in model size investigated here. Class-specific parameters may improve some aspects of model performance but negatively affect other aspects. 相似文献

This article examines the problem of specification error in 2 models for categorical latent variables; the latent class model and the latent Markov model. Specification error in the latent class model focuses on the impact of incorrectly specifying the number of latent classes of the categorical latent variable on measures of model adequacy as well as sample reallocation to latent classes. The results show that the clarity of remaining latent classes, as measured by the entropy statistic depends on the number of observations in the omitted latent class—but this statistic is not reliable. Specification error in the latent Markov model focuses on the transition probabilities when a longitudinal Guttman process is incorrectly specified. The findings show that specifying a longitudinal Guttman process that is not true in the population impacts other transition probabilities through the covariance matrix of the logit parameters used to calculate those probabilities. 相似文献
