The hypothesis testing knowledge blend     

Ted?RandlesEmail author  Christopher D?Blades  Adam?Fadlalla 《知识管理研究与实践》2008,6(4):339-349

The creation of several forms of knowledge that would enable organizations to ask and say the right things during complex diagnoses is proposed. Based on the concept of knowledge combustion, the hypothesis testing knowledge blend (HTKB) is the cognitive equivalent of petrol for the combustion engine. The HTKB requires the creation of a knowledge hybrid that uses existing technologies to ask and say the right things. In addition to timing mechanisms and problem space maps, two forms of declarative knowledge (directions and explanations) are integrated to create the HTKB. These directions and explanations would be obtained directly from the video recordings of diagnosticians conducting teleconsultations. By providing these profound dialogues during the conduct of complex diagnoses, the HTKB should increase the knowledge capital of organizations. Formal analyses are beginning to validate the conceptual structure (blue print) presented in this paper, and the results will be provided in the future.  相似文献   

Genetic etiology of spelling deficits in the Colorado and London twin studies of reading disability     

J. C. Defries  Jim Stevenson  Jacquelyn J. Gillis  Sally J. Wadsworth 《Reading and writing》1991,3(3-4):271-283

The basic multiple regression model for the analysis of selected twin data (DeFries and Fulker 1985, 1988) was fitted to spelling data from 100 pairs of MZ twins and 71 pairs of same-sex DZ twins tested in the Colorado Reading Project (DeFries, Olson, Pennington and Smith 1991), and to data from 12 pairs of MZ twins and 15 pairs of same-sex DZ twins tested in the London twin study of reading disability (Stevenson, Graham, Fredman and McLoughlin 1984, 1987). Estimates of h _g ² obtained from analyses of these data suggest that about 60% of the deficit of probands is due to heritable influences in both samples. When a regression model was fitted separately to data from males and females in the combined Colorado and London samples, resulting estimates of h _g ² were 0.66±0.18 and 0.56±0.19, respectively, a nonsignificant difference. Collaborative analyses of data from additional twin studies of reading disability would facilitate more rigorous tests of hypotheses of differential genetic etiology as a function of group membership.  相似文献   

Contexts for Independent Learning     

Ted Glynn 《教育心理学》1985,5(1):5-15

One major world view that dominates the field of developmental psychology is the organismic world view. This world view depicts individuals, including children, as active agents who know the world in terms of their own operations upon it. Individuals are seen as being in control of their own learning. This control is exercised by individuals initiating and maintaining their own learning opportunities within a responsive social context.

The responsive social context is increasingly seen by developmental psychologists (Bronfenbrenner, 1979; Wood, 1982) as of fundamental importance for the acquisition of intellectual skills. It is within responsive social contexts that individuals acquire not only specific skills but also generic knowledge about how to learn. It is this generic knowledge that allows individuals a measure of control over, and hence independence in, these social contexts.

Educational policy statements, school prospectuses and, more recently, the Core Curriculum, abound with aims and objectives to do with achieving individual autonomy and independence as a learner. Yet there is growing evidence that in many contemporary classrooms at primary, secondary and tertiary levels, we may be providing precisely the wrong contexts for students to become autonomous and independent learners. Too many classroom learning environments simply do not qualify as responsive social contexts. Individual learners have minimal control over learning interactions and hence are excessively dependent on external control by teachers.

Theoretical explanations for differences between unskilled and skilled performance are being sought increasingly in terms of characteristics of the specific contexts in which performance occurs and less in terms of qualitative differences in global capacities or in thinking processes between individuals (Wood, 1982). For example, differences in complexity of oral language between three‐year‐old children might be explained by differences in the amount and quality of language exchange with caregivers. They might also be explained by differences in caregiver skills in interpreting and responding to needs signalled by an individual child's use of language in a particular context. If we are genuinely concerned about aims of autonomy and independence in learning, then we need to discover and analyse those characteristics of responsive environments which support and promote independent learning. On the basis of existing research it is possible to specify four such characteristics of responsive learning contexts.

A Self‐Management Strategy for Increasing Implementation of Behavioural Procedures by Residential Staff     

Ted Glynn  Beryl Clark  Wendy Vaigro  Susie Lawless 《International Journal of Disability, Development & Education》1984,31(3):209-222

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   

Prevalence,School Progress and Referral of Mildly Retarded Children in Regular Classes     

Tony Cooper  Keri Wilton  Ted Glynn 《International Journal of Disability, Development & Education》1985,32(1):5-11

This study sought to determine the prevalence of mildly retarded children in a sample of 312 primary school classes (N (pupils) = 8,967). Schools were chosen at random from each of the eight Psychological Service districts of metropolitan Auckland; all Grade 2‐5 classes in the sample schools were included in the investigation. Eighty percent of the teachers surveyed believed they had one or more mildly retarded children in their classes, yielding an overall prevalence rate of 8.04 percent (N = 721). Approximately one‐third of the children designated as mildly retarded were considered by their teachers to be not coping academically as well as socially, but of these 75 percent had not been referred for special educational consideration. Comparisons among the eight districts revealed that prevalence/referral rates and characteristics of identified/referred children did not differ significantly across districts. Results are discussed in terms of their policy implications for the identification and referral of mildly retarded children in need of special educational services.  相似文献   

In the Midst of Doubled Imaginaries: The Pacific Community as Diversity and as Difference   总被引：1，自引：0，他引：1  

Ted T. Aoki 《Interchange》1999,30(1):27-38

How shall we understand the signified "community" as in a Pacific Community? Conventional understanding of "community" privileges community understood as diversity, a collective of multiple identifiers of cultures and nations (as in multiculturalism or multinationalism). Postcolonialists, like Stuart Hall and Homi Bhabha, claim that such imaginary is inscribed in "democractic liberalism," suppressing, concealing, and containing the imaginary of "community as difference." In this article, the author calls upon readers to move boldly into the interspace midst these two imaginaries, and claims that though it is a site of ambiguity, ambivalence, and uncertainty, it may be a site of generative possibilities and hope for newness, a site of becoming in struggle.  相似文献   

Shared Reading by Cambodian Mothers and Children Learning English as a Second Language: Reciprocal Gains     

Ted Glynn  Vin Glynn 《International Journal of Disability, Development & Education》1986,33(3):159-172

Subjects were five Cambodian mother‐child pairs. Three mothers (Group One) had received one year's schooling, and two (Group Two) had had no schooling in Cambodia; all children were participating in regular primary school class reading programs and receiving individual help from an ESL teacher. Group One was introduced to Shared Reading in a multiple baseline across‐subjects design, while an AB design was used for Group Two. Probes were taken of mothers and children reading individually from unseen books at the same level as those used in Shared Reading. During the Shared Reading program the Group One mothers and children markedly increased their rate of progress through book levels as did the Group Two children, but the Group Two mothers did not, although there was some evidence of minor progress in word recognition. Results are discussed in terms of the importance of the interactive social context for acquiring literacy skills.  相似文献   

Genetic and environmental influences on reading and listening comprehension     

Janice M. Keenan  Rebecca S. Betjemann  Sally J. Wadsworth  John C. DeFries  Richard K. Olson 《Journal of Research in Reading》2006,29(1):75-91

We report preliminary behaviour genetic analyses of reading and listening comprehension from The Colorado Learning Disabilities Research Center. Although the twin sample with these new measures is still of limited size, we find substantial, and significant, genetic influences on individual differences in both reading and listening comprehension. In addition, word recognition and listening comprehension each accounted for significant independent genetic influences on reading comprehension. Together, they accounted for all the genetic influence on reading comprehension, indicating a largely genetic basis for the ‘simple model’ of individual differences in reading comprehension proposed by Hoover and Gough (1990) .  相似文献   

Differential genetic etiology of reading disability as a function of IQ   总被引：5，自引：0，他引：5  

Wadsworth SJ  Olson RK  Pennington BF  DeFries JC 《Journal of learning disabilities》2000,33(2):192-199

To test the hypothesis that the genetic etiology of reading disability differs as a function of IQ, composite reading performance data from 223 pairs of identical twins and 169 pairs of same-gender fraternal twins in which at least one member of each pair was classified with reading disability were subjected to multiple regression analysis (DeFries & Fulker, 1985, 1988). In the total sample, heritability of the group deficit in reading performance (h(g)2) was .58 (+/- .08). However, when the basic regression model was fitted separately to data from twin pairs with average Wechsler (1974, 1981) full scale IQ scores below 100 or 100 and above, resulting estimates of h(g)2 were .43 and .72, respectively, a significant difference (p < or = .03, one-tailed). The results of fitting extended regression models to reading performance and continuous IQ data provide evidence that the genetic etiology of reading disability differs as a linear function of IQ (p < or = .007, one-tailed). These results suggest that IQ is relevant for the diagnosis of reading disability and that environmental influences may be more salient as a cause of reading difficulties in children with lower IQ scores.  相似文献   

Meeting the challenge of HIV and AIDS in the classroom     

Donna E. Wadsworth Ph.D.  Diane Knight 《Early Childhood Education Journal》1996,23(3):143-147

Contemporary early childhood teachers are facing new challenges as children who test HIV positive or who have AIDS enter the classroom. Providing appropriate health care and educational programs for these children is a major concern of teachers. This article presents a brief discussion of guidelines and issues that might be addressed in an in-service for teachers in general education to prepare them for a student with HIV or AIDS in their classrooms.  相似文献
