The materials, procedures and findings of an evaluation of initial approaches to the use of audio visual media in a course teaching the French language to distance learners are reported as a case study of a formative evaluation. The study illustrates the design-research-revision stages of the formative evaluation cycle. Innovative features of the course were the pivotal role played by audiovisual (videocassette and audiocassette) media in providing resource material for teaching and learning, the use of short sequences for intensive study and the high degree of integration between the audiovisual media and the print. Key teaching design features of the draft audiovisual and print packages were identified and evaluated in terms of students’ reactions to them. Central issues of teaching design are discussed in relation to revisions made to the course materials in the light of the evaluation. 相似文献

The relationship between education policy and workforce policy has long been uneasy. It is widely believed in many quarters of American society that the U.S. education system is in decline and, what’s more, that it bears significant responsibility for a wide range of social ills, including stagnant wages, increasing inequality, high unemployment, and overall economic lethargy. However, as analyzed in this paper, the preponderance of evidence suggests that the U.S. education system has produced ample supplies of students to respond to STEM labor market demand. The “pipeline” of STEM-potential students is similarly strong and expanding.

A pipelined architecture for distributed text query evaluation 总被引:1,自引:0,他引:1

Two principal query-evaluation methodologies have been described for cluster-based implementation of distributed information
retrieval systems: document partitioning and term partitioning. In a document-partitioned system, each of the processors hosts
a subset of the documents in the collection, and executes every query against its local sub-collection. In a term-partitioned
system, each of the processors hosts a subset of the inverted lists that make up the index of the collection, and serves them
to a central machine as they are required for query evaluation.
In this paper we introduce a pipelined query-evaluation methodology, based on a term-partitioned index, in which partially
evaluated queries are passed amongst the set of processors that host the query terms. This arrangement retains the disk read
benefits of term partitioning, but more effectively shares the computational load. We compare the three methodologies experimentally,
and show that term distribution is inefficient and scales poorly. The new pipelined approach offers efficient memory utilization
and efficient use of disk accesses, but suffers from problems with load balancing between nodes. Until these problems are
resolved, document partitioning remains the preferred method.

This article focuses on teachers’ experiences of supporting looked after and adopted children in one case study primary school in England. Children who are looked after and adopted may have a disrupted attachment with their primary carer which has resulted in an insecure attachment. Children with insecure attachments can feel anxious, uncertain and have low self-worth which can result in a struggle to adapt to school as they are unable to articulate their feelings. This article draws on qualitative research using semi-structured interviews with teaching staff in order to illuminate strategies, subsidised through Pupil Premium Plus funding, to support such children. A key outcome was the creation of a school-based model consisting of six main components that can be developed to support children with insecure attachments. 相似文献

This paper examines the construction of ‘socially just’ curriculum renewal initiatives for Samoan students in a low socio-economic secondary school. Basil Bernstein's concept of recontextualization is used to investigate the implementation of Queensland's Social Justice Strategy at the school level. Interview data provided by the school's first two ‘social justice coordinators’ is analysed, focussing on the categorizations of students and discourses operative within the reform initiatives. Shifts in what counted as socially just curriculum for Samoan students are documented. The focus is on the varying strength of the boundaries of cultural categories (i.e. ‘Samoan’) and on tensions over the emphasis on the cultural knowledge of community representatives and the professional knowledge of school educators. The findings make explicit implications for the distribution of discursive resources to the Samoan students and, hence, life chances in a world in which English is a tool needed by young Australians irrespective of their cultural background. 相似文献

Two preliminary studies explored the use of a self‐management strategy as a component of a training program for residential Child and Family Workers. The self‐management strategy comprised the Correspondence Training procedures of Risley (1977) and the formulation of specific implementation plans (Sanders & Glynn, 1981). Experiment 1 found that prompting staff to formulate plans of how they would implement target behaviour management skills and providing individual feedback on their performance in accordance with their plans resulted in gains in implementation of target skills; no gains in implementation resulted from Instruction and Group Feedback conditions alone. This experiment examined pooled data from 18 staff collected by regular time sampled observations. Experiment 2 introduced similar procedures in a multiple baseline design to four volunteer staff, each of whom selected two target behavioural skills from the training manual. The self‐management strategy resulted in clear gains in implementation of these self‐selected target skills by all four staff. Results are discussed in terms of the potential of the correspondence training paradigm and the formulation of specific implementation plans as an approach to on‐the‐job training of residential staff. 相似文献
