Multiple-choice (MC) reading comprehension test items comprise three components: text passage, questions about the text, and MC answers. The construct validity of this format has been repeatedly criticized. In three between-subjects experiments, fourth graders (N 1 = 230, N 2 = 340, N 3 = 194) worked on three versions of MC items from the Progress in International Reading Literacy Study 2001 reading comprehension test with relevant components successively deleted: “original version” (text, questions, MC-answers), “version without text” (questions, MC-answers), “version without text and without questions” (only MC-answers). Answering correctly the MC items became more difficult as the relevant information was eliminated. In the two narrative fictional texts presented, the students' performance of the version without text was not better than chance. Conversely in the informational (fictional) text, the students' performance of the version without text was better than chance. In the third condition, students' performance was never better than chance. 相似文献

This study focused on combining both the group- and individual-level analyses in studying a collaborative activity in technology-enhanced interactions in a higher education setting. The aim was to make visible, with empirical examples, the quality of the students' web-based discussions and trace the route for shared understanding. By quantifying various communicative functions, the analysis provided general knowledge on the quality and purpose of the discussion in the group and highlighted the different functional positions each student had within the group. However, only a detailed interpretative analysis of the relationships between specific thematic contents, communicative functions, and the collaborative features of the discussion, in the temporal frame, made it possible to trace and gain a deeper understanding of the true acts of collaboration. It also highlighted the individual participants' different participatory and discursive positions in the different phases of the task. Over the study, it became evident that any attempts to define a collaborative activity from either the group's or individual's perspective would only result in a partial interpretation of the collaborative enterprise. 相似文献

AbstractAbsence from sport participation among girls from ethno-cultural minorities is often highlighted as an inclusion policy challenge. Based on 35 interviews with community sports coaches, managers and partners, we explore how the absence of girls is problematized in four Swedish sports-based interventions, focusing on how problems, as well as the means and the ends of social inclusion, are articulated. The girls are assessed as being in need of social change due to their alleged social exclusion. Absence is explained by “patriarchal norms” as well as by the introvert conduct of the girls themselves. Girls-only sports activities performed by female coaches as role models are described as a way for girls to gain social inclusion and to become emancipated from subjugating norms. In conclusion, participation in community sport is highlighted in discourse as crucial for adopting powers of emancipation. A similar discourse could be recognized elsewhere, inside and outside the realm of sport. 相似文献

This study examined whether defending and passive bystanding during peer victimization episodes were associated with individual- and classroom-level efficacy to stop peer victimization. Self-report survey data were analyzed from 1,467 Swedish fourth-grade students (mean age = 10.55) from 100 classrooms in 63 schools. Multilevel analyses revealed that, when witnessing peer victimization, students more often defended victims if they were high in defender self-efficacy and if they belonged to classrooms high in collective efficacy. In contrast, students were more likely to remain passive if they were low in defender self-efficacy and if they belonged to classrooms low in collective efficacy. Taken together, our findings suggest that efficacy beliefs both at the individual and at the classroom level contribute to explaining variability in students' bystander behaviors, which has potential implications for prevention and intervention work. 相似文献

Most of the fastest-growing string collections today are repetitive, that is, most of the constituent documents are similar to many others. As these collections keep growing, a key approach to handling them is to exploit their repetitiveness, which can reduce their space usage by orders of magnitude. We study the problem of indexing repetitive string collections in order to perform efficient document retrieval operations on them. Document retrieval problems are routinely solved by search engines on large natural language collections, but the techniques are less developed on generic string collections. The case of repetitive string collections is even less understood, and there are very few existing solutions. We develop two novel ideas, interleaved LCPs and precomputed document lists, that yield highly compressed indexes solving the problem of document listing (find all the documents where a string appears), top-k document retrieval (find the k documents where a string appears most often), and document counting (count the number of documents where a string appears). We also show that a classical data structure supporting the latter query becomes highly compressible on repetitive data. Finally, we show how the tools we developed can be combined to solve ranked conjunctive and disjunctive multi-term queries under the simple \({\textsf{tf}}{\textsf{-}}{\textsf{idf}}\) model of relevance. We thoroughly evaluate the resulting techniques in various real-life repetitiveness scenarios, and recommend the best choices for each case. 相似文献

This paper presents the argument that education and the teaching profession have been saturated by a new form of risk consciousness and risk consideration. The aim is to shed light on this issue and present a number of empirical examples and questions of interest in educational research. Furthermore, the paper presents some of the central theories regarding risk and an attempt is made to relate these theories to an epistemological framework. The article also emphasizes the problems and issues that arise from the way teachers think, experience and manage risk in their daily work, and examines how this affects their didactic intentions and, in the long run, also the pupils’ learning potential. It is the intention of the authors, in the scientific as well as in the professional discussion, to reintroduce the positive connections between teaching and risk zones, as well as between professional development and risk taking. 相似文献

In this study, parent-child interaction in two carefully matched subgroups-school-age boys with learning disabilities (LD) who showed a discrepancy between their verbal IQ and performance IQ and had more extensive difficulties in higher-level language abilities (VIQ < PIQ, n = 8) and boys with LD who did not manifest a discrepancy between verbal IQ and performance IQ (VIQ = PIQ, n = 8), were investigated. The effects of the child's language problems on child task performance and on the quality of maternal communication were analyzed in a mother-child problem solving task. Children in the VIQ < PIQ group were found to be less successful on the task than children in the VIQ = PIQ group, and their mothers exhibited lower communication clarity in their instructions than the mothers of the children in the VIQ = PIQ group. An interesting interaction effect was found for communication deviances. For mothers in the VIQ < PIQ group the extent of deficient communication increased from the monologue to the dialogue situation, whereas communication deviances decreased for mothers in the VIQ = PIQ group. Three possible models are discussed in light of the differences between the subgroups. 相似文献

In this paper, it is argued that e‐learning environments are currently more like ‘buildings’, ie, learning spaces, rather than ‘schools’, ie, places for learning. The concepts originated from architecture and urban design, where they are used both to distinguish static spaces from inhabited places, and more importantly, as design objectives. The transformation from space to place is supported and enabled by social interactions between the (learning) community members. We argue that this distinction between the concepts explains some of the problems with current e‐learning systems and propose issues to consider when designing new systems. By acknowledging the importance and characteristics of a place, designers and researchers can justify the need and support for social interactions in learning space, consequently enabling social community building in e‐learning environments, and most importantly, supporting the development of a user‐friendly and motivating e‐learning place. 相似文献

Visuospatial working memory in adolescents with poor performance in mathematics: variation depending on reading skills 总被引:2,自引:1,他引:1
Minna Kyttälä 《教育心理学》2008,28(3):273-289
The first purpose of this study was to investigate whether the visuospatial working memory (VSWM) skills of 15–16‐year‐old pupils with difficulties in mathematics differ from those of their normally achieving peers. The goal was to broaden the view of the complex system of VSWM. A set of passive and active VSWM tasks was used. The study’s second purpose was to investigate whether pupils with mathematical difficulties differed in their VSWM skills based on whether they had signs of reading deficits or not. Results indicate that the pupils with poor performance in maths showed poorer performance on certain VSWM tasks. The group with deficits only in maths had less capacity for storing passive visual simultaneous information, while the group with difficulties both in maths and reading had deficits in both storing (passive visual and visuospatial information) and processing, and had less ability to control irrelevant visuospatial information compared to their peers of the same age. The results indicate a general VSWM deficit in pupils with both mathematics and reading problems and a specific VSWM deficit in pupils with only mathematics problems. 相似文献
