Subscore added value analyses assume invariance across test taking populations; however, this assumption may be untenable in practice as differential subdomain relationships may be present among subgroups. The purpose of this simulation study was to understand the conditions associated with subscore added value noninvariance when manipulating: (a) subdomain test length, (b) differences in subgroup mean ability, and (c) subgroup differences in intersubdomain correlations. Results demonstrated that subscore added value was noninvariant for 24–100% of replications (depending on subdomain test length) when the subgroup difference in intersubdomain correlation was equal to .30. To examine if this condition was met in practice, applied invariance analyses of three operational testing programs were conducted. Across these datasets, noninvariant subscore added value was present for some subdomains across sex and ethnic subgroups. Overall, these results indicate that subscore added value noninvariance is largely driven by differential intersubdomain correlations among subgroups, which may be present in some operational testing programs. 相似文献

This study is based on the hypothesis that television contents themselves constitute a source of learning through television narratives. In specific terms, we defend the idea that it is possible to teach and learn values through said narratives. Some of the research dealing with the relationship between television and values is categorized from a three-fold standpoint: the contents themselves, the medium itself and the language. As a result of this review, we maintain that reiterated attacks on television, blaming it for the majority of problems suffered by young people today, are not supported by the studies carried out by psychologists over recent decades. We believe that viewers incorporate the information provided by television from different contexts and that the enculturation is not unidirectional. There is an interrelation between development contexts and messages. We are specifically interested in analyzing the implicit and explicit values underlying television contents. Thus, based on the model developed by Schwartz and Bilsky, we have compiled a questionnaire (Val-TV 0.1) with the aim of classifying values and interpreting the behaviours visualized in television texts, and relating them to adolescents’ own values. 相似文献

Why are some teachers more effective than others? The importance of understanding the interplay between teacher preparation, pedagogy and student achievement has motivated a new line of research focusing on teacher knowledge. This study analyses the effects of teacher mathematics knowledge on student achievement using longitudinal data from rural Guatemalan primary schools. After presenting a conceptual framework for linking the work of the teacher with student learning in mathematics together with an overview of the different forms of teacher knowledge, the paper introduces the Guatemalan context and the analytical framework including the sample, data and methods. Overall, the results provide some empirical support for a widely held, if infrequently tested, belief in mathematics education: effective teachers have different kinds of mathematical knowledge. The results also suggest specific mechanisms by which effective teachers can make substantial impacts on student learning, even in extremely poor contexts. 相似文献

ABSTRACTReading is a tool that promotes the learning of science across schooling. Scientific texts are conceptually and linguistically complex, especially for students from low-income contexts because they have neither the experience with the language nor the literacy skills to face the challenges of scientific knowledge. This study used a mix method approach to compare the cognitive scaffolding practiced by teachers during science reading activities in high- and low-performing schools. Three teachers and 141 fourth grade students from low socioeconomic background schools participated in 48 class sessions. Classes were video-recorded and transcribed. The data were analyzed using Sanchez’ Pedagogic Practice Analysis System. The results show that teachers from both types of schools continuously use reading as a tool for learning. The effective teacher uses reading with non-invasive scaffolding and varied verbal participation to elaborate knowledge, promoting literal and inferential comprehension and more opportunities for the students to construct knowledge. By contrast, less effective teachers use reading with invasive scaffolding and little verbal participation of the students to consolidate knowledge, promoting mainly literal comprehension. This study shed light on different approaches teachers use to foster reading comprehension for science learning. 相似文献

Curriculum reforms have led to discursive and organizational changes in Argentina. These reforms have reshaped school knowledge and institutional patterns of school administration. We analyse the process of this 'curriculum reterritorialization', the contradictions and displacements it produces, and the hybrid products that result from it. Reterritorialization is traced through four interrelated movements: the hybridization of discourses; the design of new maps of relations between the centre and the periphery of the educational system; the new 'regime of truth' that emerges out of these changes; and the role of the intellectual in educational reform. Although they are different in scope and magnitude, these movements provide the tools required to analyse the many ways in which curriculum reform is transforming Argentina's educational experiences. 相似文献
