Over time, researchers have acknowledged the importance of understanding the users’ strategies in the design of search systems. However, when involving users in the comparison of search systems, methodological challenges still exist as researchers are pondering on how to handle the variability that human participants bring to the comparisons. This paper present methods for controlling the complexity of user-centered evaluations of search user interfaces through within-subjects designs, balanced task sets, time limitations, pre-formulated queries, cached result pages, and through limiting the users’ access to result documents. Additionally, we will present our experiences in using three measures – search speed, qualified search speed, and immediate accuracy – to facilitate the comparison of different search systems over studies. 相似文献

Abstract Interactives—computers and other multimedia components, physical manipulatives (including whole‐body and tabletop activities), and simulations—occur in all types of museums. There is considerable interest in the nature of the learning that happens when visitors use interactives. Museum professionals have enlisted constructivist theory to support the notion that interactive elements are invaluable components of any exhibition experience, and are effective learning tools that enable active visitor engagement. Interactives are also seen as vital to sustaining institutional image and expanding institutional popularity. Despite the increasing use of interactives in exhibitions and the substantial investments being made in their design and maintenance, there is a paucity of research as to whether these constructivist assumptions are supported. There is little work exploring visitors' perceptions of specific types of interactives, or the role of interactivity in the visitor experience generally. Museum staff thus have a limited ability to make informed decisions about the level and type of interactivity that might enhance exhibition experiences. This paper describes a collaborative effort in 2001 by researchers at the Powerhouse Museum (PHM), Sydney; the Institute for Learning Innovation (the Institute), Annapolis, Maryland; and Curtin University of Technology (Curtin) and Scitech Discovery Centre (Scitech), both in Perth, Western Australia. This study investigated two aspects of interactivity: 1) visitor perceptions of interactivity in two different contexts, a museum and a science center; and 2) the types of short‐ and long‐term learning that resulted from use of interactives in these two institutions. 相似文献

Novalis, the Early German Romantic poet and philosopher, had at the core of his work a mysterious depiction of the ‘absolute’. The absolute is Novalis’ name for a substance that defies precise knowledge yet calls for a tentative and sensitive speculation. How one asserts a truth, represents an object, and sets about encountering things in the world, is in the first instance the domain of the absolute, which diffuses through all things in the world. In this article, I begin by describing the absolute in general and I outline its importance in Novalis’ works. I then speculate on its natural tendency to render an object mysterious and fundamentally unknowable. Although the absolute also allows us an insight into an object, my attention in this article is drawn to its concealment in mystery because, as Novalis was at pains to indicate, the Enlightenment has been more than generous to the clear perception of an object. I turn to consider the poet—a most important political character in Novalis’ works—and their Bildung (educative formation) of themselves and their communities. They bring their communities to continual maturation through their role in romanticising the ordinary world and through their need to consistently reflect on, and be aware of, the absolute. They also develop themselves in their ongoing state of mystery as they carry out their political and poetic responsibility. 相似文献

ABSTRACTThis paper considers the emancipatory potential of incorporating youth participatory action research (YPAR) and restorative practices (RP) implementation into a transformative mixed methods study design as a means to create equitable and caring school systems for marginalized youth. The utilization of transformative mixed methods research offers a methodological orientation to legitimize, illuminate, and prioritize perspectives from marginalized youth that may be undervalued, decontextualized, and oversimplified in traditional quantitative and qualitative research methodologies. Furthermore, the authors suggest that YPAR and RP align with Critical Theory and Quantitative Criticalism, which are theoretical and methodological frameworks consistent with the transformative paradigm. The integration of these various theoretical, methodological and applied frameworks provides researchers opportunities to flatten hierarchies and actively engage marginalized youth to address the structural and programmatic inequities they experience in schools. Informed by the authors’ multi-year university-school district action research partnership, this paper explores how the alignment of YPAR, RP, and transformative mixed methods may promote critical consciousness amongst students, families, staff, and administration in schools. Finally, we also demonstrate how social science researchers can blend YPAR, RP, and transformative mixed methods design to partner with school districts to address structural societal problems, such as racism and inequity. 相似文献

Public Libraries tout that they serve diverse communities, even having collection development policies, programs, and service that recognize their dissimilar neighborhoods. The authors of this article, having noted the influx of Arab‐speaking populations from Iraq and other Middle East countries to the United States, sought to find out the extent to which this population was receiving library service. The investigators discovered that four Michigan counties comprise a significant Arab‐speaking population; in fact, that population base is surpassed only by that of the Middle East countries and Paris, France. The researchers constructed a survey, based on a successful model used with libraries serving Spanish‐speaking populations and applied it to the Michigan libraries in the counties with a significant Arab‐speaking population. The results reveal that the Arab‐speaking neighborhoods, at least at the time of the survey, were not very well served (except in a few instances) by their public libraries. 相似文献

This paper presents a prospective study aimed at identifying the predictors of academic achievement among first-year university students. It tries to develop an inclusive view of academic achievement by taking into account the possible differential impact of several predictors in two different faculties of the university. Some 317 university students from the two faculties (science and physical education), who were in their first year at university, participated in the study. During the academic year, these students completed a questionnaire. The outcome variable was their average academic mark at the end of the year. Multiple regression analyses were performed to identify the most powerful predictors of achievement. The results showed that past school failure, parental education and self-efficacy beliefs predicted achievement in both programs. Age, secondary-school specialisation, reasons for choosing the program, deep processing, time spent studying and intention to persist have also been highlighted as significant predictors of success, but only in one of the two faculties. Self-efficacy was the most powerful predictor of achievement in physical education courses, whereas intention to persist was the most powerful predictor in science. These results show the importance of adopting an integrated and contextualised approach to exploring the predictors of academic achievement at university. 相似文献

The notion of flow of a proof encapsulates mathematical, didactical, and contextual aspects of proof presentation. A proof may have different flows, depending on the lecturer’s choices regarding its presentation. Adopting Perelman’s New Rhetoric (PNR) as a theoretical framework, we designed methods to assess aspects of the flow of a proof. We present a case study from a Number Theory class at the beginning undergraduate level, focusing on an intervention concerning one lesson given in two consecutive years. The intervention consisted of a discussion with the lecturer about findings from Year-1 and potential changes in the flow of the proof before the Year-2 lesson. We analyze two aspects of the flow of the proof: the scope and organization of the argumentation and the presence (in the PNR sense) of different elements. Our analysis revealed that the intervention caused global and local changes in the flow and that PNR enables us to capture these changes. 相似文献
