Immersed in Design: Using an Immersive Teaching Space to Visualise Design Solutions     

Lisa Chandler  Alistair Ward 《The International Journal of Art & Design Education》2019,38(2):314-327

A significant component of design pedagogy is the need to foster critical design thinking and to support students in understanding links between educational exercises and their potential application in professional design practice. Problem solving is central to design so it is also essential that students understand that there can be multiple solutions to a design brief, and are supported in creative experimentation and in generating imaginative outcomes. This article examines some innovative approaches to addressing these pedagogical needs. It investigates the effectiveness of pedagogical design incorporating the Immerse Lab, a three‐wall projection room at an Australian university, as a learning context for design practice, for generating ideas and for supporting learning involving the comparative display of design outcomes. Anonymous student survey results revealed that the majority of students found learning in the Immerse Lab to be beneficial; comparative review more effective than in standard tutorial rooms; that the activity generated new ideas; it encouraged students to think differently about their designs; and it inspired students to develop their existing designs or create new ones. The project demonstrated that curricula involving immersive spaces can be effective in supporting engaging and relevant design pedagogy.  相似文献   

A Murray Cod assemblage: Re/considering riverScape pedagogy     

Alistair James Stewart 《The Journal of environmental education》2018,49(2):130-141

ABSTRACT

This article enacts Deleuze and Guattari's (1987 Deleuze, G., & Guattari, F. (1987). A thousand plateaus: Capitalism and schizophrenia (B. Massumi, Trans.). Minneapolis, MN: University of Minnesota Press. (Original work published in 1980) [Google Scholar]) concept assemblage to craft a riverScape pedagogy that is informed by, and responsive to, the Murray Cod, the river, and its circumstances. The Murray Cod, the largest fish species in Australia's Murray-Darling Basin, has diverse cultural meanings. Cod are at once a creation being of Indigenous people, a migratory predator that breeds in response to warm floodwaters, and a fish suffering significant ecological decline as a result of changes to land and water use in its habitat. Murray Cod assemblage weaves these elements together to re/create a bioegalitarian pedagogy, part thought experiment and part teaching strategy.  相似文献   

The Use of Computers in the Education of Open University Students with Disabilities     

Alistair D. N. Edwards 《Educational Media International》2013,50(2):100-103

Abstract

In 1988 the Open University is implementing a major new policy on the use of computers in its courses; students taking certain courses will be obliged to have access to a microcomputer. This new policy has many far‐reaching consequences, not least for students who are disabled. In the past most computing in Open University courses has been done by students using terminals in local study centres, linked to the University's mainframe computers. Also, a number of students who are disabled have used computers in their studies, principally for word‐processing written work. By interviewing disabled students who have taken such courses, and surveying other disabled students, it has been possible to anticipate to some extent the likely impact of the home‐computing (HC) policy. Results suggest that for many disabled‐ students the HC policy represents an improvement in their opportunities; now they will be able to study courses involving computers entirely at home. However, a number of problems have also been identified. Hopefully, as many of these have been recognised at an early stage, it will be possible to address them before they affect students directly.  相似文献   

Binary Interpolative Coding for Effective Index Compression   总被引：5，自引：1，他引：4  

Alistair Moffat  Lang Stuiver 《Information Retrieval》2000,3(1):25-47

Information retrieval systems contain large volumes of text, and currently have typical sizes into the gigabyte range. Inverted indexes are one important method for providing search facilities into these collections, but unless compressed require a great deal of space. In this paper we introduce a new method for compressing inverted indexes that yields excellent compression, fast decoding, and exploits clustering—the tendency for words to appear relatively frequently in some parts of the collection and infrequently in others. We also describe two other quite separate applications for the same compression method: representing the MTF list positions generated by the Burrows-Wheeler Block Sorting transformation; and transmitting the codebook for semi-static block-based minimum-redundancy coding.  相似文献

Solving the mystery of vanishing rivers in China     

Yichu Wang  Jinren Ni  Yao Yue  Jiaye Li  Alistair G L Borthwick  Ximing Cai  An Xue  Li Li  Guangqian Wang 《国家科学评论(英文版)》2019,6(6):1239

A major controversy was sparked worldwide by a recent national water census claiming that the number of Chinese rivers with watersheds ≥100 km² was less than half the previous estimate of 50 000 rivers, which also stimulates debates on the potential causes and consequences. Here, we estimated the number of rivers in terms of stream-segmentation characteristics described by Horton, Strahler and Shreve stream-order rules, as well as their mixed mode for named rivers recorded in the Encyclopedia of Rivers and Lakes in China. As a result, the number of ‘vanishing rivers’ has been found to be highly relevant to statistical specifications in addition to the erroneous inclusion of pseudo-rivers primarily generated in arid or frost-thaw areas. The modified Horton stream-order scheme reasonably depicts the configuration of complete natural streams from headwater to destination, while the Strahler largely projects the fragmentation of the named river networks associated with human aggregation to the hierarchical river systems.  相似文献   

Click-based evidence for decaying weight distributions in search effectiveness metrics     

Yuye Zhang  Laurence A. F. Park  Alistair Moffat 《Information Retrieval》2010,13(1):46-69

Search effectiveness metrics are used to evaluate the quality of the answer lists returned by search services, usually based on a set of relevance judgments. One plausible way of calculating an effectiveness score for a system run is to compute the inner-product of the run’s relevance vector and a “utility” vector, where the ith element in the utility vector represents the relative benefit obtained by the user of the system if they encounter a relevant document at depth i in the ranking. This paper uses such a framework to examine the user behavior patterns—and hence utility weightings—that can be inferred from a web query log. We describe a process for extrapolating user observations from query log clickthroughs, and employ this user model to measure the quality of effectiveness weighting distributions. Our results show that for measures with static distributions (that is, utility weighting schemes for which the weight vector is independent of the relevance vector), the geometric weighting model employed in the rank-biased precision effectiveness metric offers the closest fit to the user observation model. In addition, using past TREC data as to indicate likelihood of relevance, we also show that the distributions employed in the BPref and MRR metrics are the best fit out of the measures for which static distributions do not exist.  相似文献   

Looking back,looking forward: celebrating a quarter century of serving distance education ‘down under’     

Alistair Inglis 《Distance Education》1999,20(1):7-30

The Open and Distance Learning Association of Australia (ODLAA) has reached 25 years of age. This article traces the development of the Association over that period. It records the major changes that have taken place in the range and types of activities of the Association and explains the circumstances that led to those changes. It concludes by attempting to identify the principal challenges facing the Association in entering its second quarter century and proposes ways in which these challenges might be addressed.  相似文献
