Heightened accountability pressures and an increased emphasis on teaching quality have directed scholarly attention to scrutinizing instruction, particularly with respect to issues of validity and reliability. However, these attempts have largely been directed toward “core” content areas and investigated generic or content-specific instructional aspects separately. Focusing on a less explored area, physical education, and concurrently attending to both instructional aspects, in this exploratory study, we examined whether the optimal lesson-rater combination needed to obtain reliable teaching-quality estimates differs depending on the type of instructional aspects considered. Data analysis of 147 lessons using generalizability theory suggested that either a 3-lesson-2-rater or a 4-lesson-1-rater combination yields sufficiently reliable estimates for nearly all dimensions examined (generic or content specific). Quality of student practice, however, required 11 lessons scored by 2 raters. These findings underline the importance of examining individual dimensions within a given observational instrument and the merit of carefully selecting and training raters. 相似文献

This article explores the attitudes and opinions of Cypriot primary teachers about the use of the Internet for their personal development and as an educational tool. It also examines the teachers’ concerns about the implementation of the Internet in schools and their opinions about what has to be done in order to ensure its effective integration into the educational settings. The research revealed that Cypriot primary teachers had positive attitudes towards using the Internet both for their professional development and as an educational tool. The only factor that appeared to have a significant positive relationship with the attitudes of the teachers was the degree of confidence in using the Internet. Additionally, teachers considered training in the use of the Internet as the most important need for its effective implementation in primary schools. 相似文献

Children exposed to institutional care often suffer from “structural neglect” which may include minimum physical resources, unfavorable and unstable staffing patterns, and socially emotionally inadequate caregiver‐child interactions. This chapter is devoted to the analysis of the ill effects of early institutional experiences on resident children's development. Delays in the important areas of physical, hormonal, cognitive, and emotional development are discussed. The evidence for and against the existence of a distinctive set of co‐occurring developmental problems in institutionalized children is weighed and found to not yet convincingly demonstrate a “postinstitutional syndrome.” Finally, shared and nonshared features of the institutional environment and specific genetic, temperamental, and physical characteristics of the individual child are examined that might make a crucial difference in whether early institutional rearing leaves irreversible scars. 相似文献

In this article, we: (1) offer a conceptualisation of what it means for Greek Cypriot teachers to be ‘reconciled’ with the ‘other side’ (i.e. Turkish Cypriots) in Cyprus; (2) examine Greek Cypriot teachers' emotional responses to the new educational objective of cultivating peaceful coexistence in schools; and (3) investigate how Greek Cypriot teachers' perceptions of reconciliation and emotional responses to the new educational objective of cultivating peaceful coexistence are entangled, and what implications these entanglements may have for educational reform efforts. This investigation is based on data collected in a national survey of Greek Cypriot primary and secondary teachers. The study is important not only for the Greek Cypriot educational system, but also for educational reform efforts in other conflict-ridden areas in Europe because it addresses a fundamental issue in relation to reconciliation: Can teachers, who may still carry traumatic experiences from a conflict and thus be (potentially) emotionally unready to engage in reconciliation, be convinced to put the past behind and promote peaceful coexistence in schools? The findings highlight the teachers' multiple ambivalences, yet they also identify openings for promoting reconciliation and peaceful coexistence in schools. The implications are discussed in terms of educational policymaking, curriculum development, and teacher training. 相似文献

The purpose of this study was to examine the simple view of reading (SVR) and contributions of verbal proficiency and reading fluency to reading comprehension for fourth‐, seventh‐ and ninth‐grade readers (N=271). The SVR explained a significant proportion of variance in reading comprehension for all grades with decreasing explained variance in higher grades. The variance explained by decoding decreased from fourth grade to higher grades. The variance explained by listening comprehension increased from fourth‐ to seventh‐grade, but did not change from seventh‐ to ninth‐grade. In all grades, verbal proficiency and reading fluency contributed substantial additional variance to reading comprehension beyond the SVR. Changes in the predictive relation between listening and reading comprehension and factors influencing reading comprehension in each grade are discussed. 相似文献

This paper examines the contribution of mathematical knowledge for teaching (MKT) and curriculum materials to the implementation of lessons on integer subtraction. In particular, it investigates the instruction of three teachers with differing MKT levels using two editions of the same set of curriculum materials that provided different levels of support. This variation in MKT level and curriculum support facilitated exploring the distinct and joint contribution of MKT and the curriculum materials to instructional quality. The analyses suggest that MKT relates positively to teachers' use of representations, provision of explanations, precision in language and notation, and ability to capitalize on student contributions and move the mathematics along in a goal-directed manner. Curriculum materials set the stage for attending to the meaning of integer subtraction and appeared to support teachers' use of representations, provision of explanations, and precision in language and notation. More critically, the findings suggest that less educative curriculum materials, coupled with low levels of MKT, can lead to problematic instruction. In contrast, educative materials can help low-MKT teachers provide adequate instruction, while higher MKT levels seem to enable teachers to compensate for curriculum limitations. 相似文献

A refutation text is designed to promote conceptual change by explicitly acknowledging commonly held misconceptions about a topic, directly refuting them, and providing an accurate explanation. In this study, we determined the impact of different types of refutation texts on adolescent readers’ conceptual change learning in science. Specifically, we manipulated the way the correct conception was justified and explained following work in epistemic cognition. Three different types of justification were compared to a control condition: justification by authority, justification by multiple sources, and justification by personal opinion. The findings showed that learning effects were optimized when the correct conceptions were presented in terms of a corroborated consensus among multiple sources. 相似文献

Teaching and learning fractions has traditionally been one of the most problematic areas in primary school mathematics. Several
studies have suggested that one of the main factors contributing to this complexity is that fractions comprise a multifaceted
notion encompassing five interrelated subconstructs (i.e., part-whole, ratio, operator, quotient, and measure). Kieren was
the first to establish that the concept of fractions is not a single construct, but consists of several interrelated subconstructs.
Later on, in the early 1980s, Behr et al. built on Kieren’s conceptualization and suggested a theoretical model linking the
five subconstructs of fractions to the operations of fractions, fraction equivalence, and problem solving. In the present
study we used this theoretical model as a reference point to investigate students’ constructions of the different subconstructs
of fractions. In particular, using structural equation modeling techniques to analyze data of 646 fifth and sixth graders’
performance on fractions, we examined the associations among the different subconstructs of fractions as well as the extent
to which these subconstructs explain students’ performance on fraction operations and fraction equivalence. To a great extent,
the data provided support to the associations included in the model, although, they also suggested some additional associations
between the notions of the model. We discuss these findings taking into consideration the context in which the study was conducted
and we provide implications for the teaching of fractions and suggestions for further research. 相似文献

The effects of epistemic beliefs and text structure on cognitive processes during comprehension of scientific texts were investigated. On‐line processes were measured using think‐aloud (Experiment 1) and reading time (Experiment 2) methodologies. Measures of off‐line comprehension, prior knowledge and epistemic beliefs were obtained. Results indicated that readers adjust their processing as a function of the interaction between epistemic beliefs and text structure. Readers with misconceptions and more sophisticated epistemic beliefs engage in conceptual change processes, but only when reading refutation texts. Results also showed that memory for text is not affected by differences in epistemic beliefs or text structure. These findings contribute to our understanding of the relations among factors associated with text comprehension and have implications for theories of conceptual change. 相似文献
