Existing structures should be exploited as best as possible in the course of document reuse. Reuse may take multiple forms: rearranging a single document so as to provide different views of the same information, copying a portion of a single document so as to provide a portion of a new document, and combining portions of existing documents to constitute a new document. We present algorithms for doing this reuse, describe some computer tools which we have built to support this reuse, and provide real examples. For significant reuse, the information in existing documents needs to be abstracted so as to highlight the conceptual patterns. Outlines are a structure which could, at least, partially support this function.  相似文献

This article reports on the findings of a study that investigated the effects of instructional conditions and prior experience on students’ self-reflection. The study was conducted with the use of a video annotation tool that was used by undergraduate performing arts students to reflect on their video-recorded performances. The study shows a consistent positive effect of previous experience with the video annotation tool for engagement with reflection. Graded instructional conditions with feedback had a positive effect on increasing higher order reflections particularly for students with prior experience with the video annotation tool for reflective purposes. The finding suggests that when including reflection in the curriculum, it is important to consider introducing it at a program or degree level rather than individual courses in order to provide an opportunity for students to gain experience with reflection and any particular tool that is used (e.g., a video annotation tool). Furthermore, reflective tasks should be scaffolded into the curriculum with ample opportunity for formative feedback and summative assessment in order to encourage higher order thinking and foster students’ metacognitive awareness and monitoring for increased goal-setting and acknowledgement of the motive or effect of their observed behavior.  相似文献

This paper illustrates a new way of working collaboratively on the development of a methodology for studying teacher agency for social justice. Increasing emphasis of impact on change as a purpose of social research raises questions about appropriate research designs. Large-scale quantitative research framed within externally set parameters has often been criticised for its limited potential for capturing the contexts and impacting change, while smaller, locally embedded, mostly qualitative inquiries have been questioned on the grounds of their limited generalizability and sometimes compromising research rigour. New ways of working collaboratively are increasingly explored as a way of reconciling research rigour and impact. The paper presents the procedures for designing a study that is both methodologically rigorous and potentially impactful. Twelve researchers, practitioners and policy-makers in Scotland were extensively involved in designing a mixed-method study of teacher agency for social justice. The Critical Communicative Methodology was employed to establish egalitarian dialogue between researchers and practitioners. The procedures and the resulting research tools can be used in future studies, including large-scale quantitative analysis. The paper discusses the challenges of ownership, choice of methods, and knowledge transfer, that need to be addressed in these ways of working.  相似文献

Building upon recent research that defines psychological development as a continuous process of sense-making situated within a cultural and historical context, this paper explores how culturally diverse youth growing up in New York City use evaluative language to enact relational complexity as they make sense of technologically mediated interpersonal interactions with their peers. Forty-four individuals (ages 15–20) participated in a quasi-experimental research workshop that engaged them in the process of sense-making by asking them to write projective narratives toward a vignette depicting text-massage mediated interpersonal interaction embedded among monocultural and bicultural group of peers. Data analyses focus on evaluative devices used by youth and manifest the relational flexibility of sense-making by immigrant youth and their U.S. born peers across diverse relational dimensions. Results suggest that immigrant youth are able to coordinate diverse ways of interpreting interpersonal interactions across relational dimensions, manifest by varied use of logical/hypothetical, causal and affective evaluative devices. In contrast U.S. born youth largely use same frequency of evaluative devices across two relational dimensions. Statistical analysis highlights the use of affect in projective narratives by exploring a discursive learning hypothesis: that higher use of emotions in the process of sense-making by U.S. born youth gradually scaffolds the use of emotions in narrative by immigrant youth.  相似文献

Research Findings: Effects of parenting quality on the academic functioning of young homeless children were examined using data from 58 children ages 4 to 7 and their parents during their stay at an emergency homeless shelter. Parenting quality, child executive function, child intellectual functioning, and risk status were assessed in the shelter, and teacher reports of academic functioning were obtained when the children began kindergarten or 1st grade. As hypothesized, parenting quality was associated with children's academic success, and this effect was mediated by executive function skills in the child. Parenting quality also had a moderating effect on risk, consistent with a protective role of high-quality parenting among children with higher risk levels. Concomitantly, children with higher risk and lower parenting quality appeared to be more vulnerable to academic problems. Practice or Policy: In homeless families, parenting may play an especially important role in academic success through multiple pathways, including the development of executive function skills in their children. Policies and practices to support parents and foster the executive function skills of young children in homeless families may be important strategies to promote child academic success. Implications for intervention efforts with homeless parents and children are discussed.  相似文献

Online shared spaces are destinations where people of common interests interact to achieve common goals or borrow each other's expertise for personal pursuits. Due to a multitude of users, such spaces generate large amounts of content, thus creating a potential for information overload. To deal with it, users of online shared spaces develop information management strategies that frequently involve the use of information technology. In this paper we present a case study of the use of widgets as information management tools in uCern, an online shared workspace where healthcare industry stakeholders get involved in various types of interactions. To understand how widgets served the purpose of information management and whether they were considered useful, we administered an online questionnaire (n = 183) followed by qualitative interviews (n = 5). Data analysis revealed that study participants used widgets as tools that promoted their situation and activity awareness of events and activities going on in uCern and helped them with organizing and accessing the content in a quick and efficient manner. We also describe issues associated with the use of widgets and their usefulness as reported by participants and propose implications for design and development of online shared spaces in relation to information management tools.  相似文献
