Districts are increasingly making personnel decisions based on teachers’ impact on student-achievement gains and classroom observations. In some schools, however, a teacher’s practices and their students’ achievement may reflect not just individual but collaborative efforts. In other settings, teachers’ instruction benefits less from the insights and support of their colleagues. This article analyzes multiple measures of teacher and teaching quality for 24 language arts teachers in New York City who teach in different types of school environments. Teachers in different value-added quartiles were observed and scored using two protocols, PLATO and CLASS. Schools were categorized as more and less functional using Department of Education environment grades. To compare the practices of higher and lower value-added teachers in more and less functional schools, we conduct MANOVAs of observation scores and use qualitative coding of field notes. We find value-added measures and observation protocols provide confirmatory information in less functional schools but provide contradictory information about teacher quality in more functional schools. Implications for teacher education, policy, and future research are discussed. 相似文献

Concept acquisition in the human infant. 总被引:1,自引:0,他引:1
The ability of 18-, 24-, and 30-week-old infants to learn conceptual categories regarding adult female faces was examined using a habituation paradigm. Little evidence for conceptual categorization occurred at 18 or 24 weeks, but at 30 weeks infants learned to respond to "a specific female face regardless of orientation" and to "female faces in general." 相似文献

This study addresses the topic of how anchoring methods for differential item functioning (DIF) analysis can be used in multigroup scenarios. The direct approach would be to combine anchoring methods developed for two-group scenarios with multigroup DIF-detection methods. Alternatively, multiple tests could be carried out. The results of these tests need to be aggregated to determine the anchor for the final DIF analysis. In this study, the direct approach and three aggregation rules are investigated. All approaches are combined with a variety of anchoring methods, such as the “all-other purified” and “mean p-value threshold” methods, in two simulation studies based on the Rasch model. Our results indicate that the direct approach generally does not lead to more accurate or even to inferior results than the aggregation rules. The min rule overall shows the best trade-off between low false alarm rate and medium to high hit rate. However, it might be too sensitive when the number of groups is large. In this case, the all rule may be a good compromise. We also take a closer look at the anchor selection method “next candidate,” which performed rather poorly, and suggest possible improvements. 相似文献

The ability to choose the larger between two numbers reflects a mature understanding of the magnitude associated with numerical symbols. The present study explores how the knowledge of the number sequence and memory capacity (verbal and visuospatial) relate to number comparison skills while controlling for cardinal knowledge. Preschool children’s (N = 140, Mage-in-months = 58.9, range = 41–75) knowledge of the directional property of the counting list as well as the spatial mapping of digits on the visual line were assessed. The ability to order digits on the visual line mediated the relation between memory capacity and number comparison skills while controlling for cardinal knowledge. Beyond cardinality, the knowledge of the (spatial) order of numbers marks the understanding of the magnitude associated with numbers. 相似文献

Current research explores adaptability by gathering teachers' reflections on their adaptations. However, the field knows little of what the term adaptability means to teachers who currently teach in today's educational context. In this article, adaptability is discussed from the perspectives of 3 practicing classroom educators, teaching in various contexts (geographic region and grade level). Teachers' voices of adaptability are examined and a definition of adaptability is discussed. Obstacles are presented in these teachers' efforts to adapt their instruction in their respective contexts. Teachers then discussed the ways in which they navigated these obstacles to modify their instruction to fit a variety of learners and experiences despite these constraints. 相似文献
