Applying a connectionist description of feedback timing     

Roy B. Clariana  Daren Wagner  Lucia C. Roher Murphy 《Educational technology research and development : ETR & D》2000,48(3):5-22

This investigation considers the effects of feedback on memory with an emphasis on retention of initial error responses. Based on a connectionist model (Clariana, 1999a), this study hypothesized that delayed-retention memory of initial lesson responses would be greater for delayed feedback compared to immediate feedback, that feedback effects will be greatest with difficult items, and that there would be a disordinal interaction of feedback timing and item difficulty. High school students (n = 52) completed a computer-based lesson with either delayed feedback, single-try immediate feedback, or multiple-try immediate feedback. There was a significant difference for type of feedback, with retention test memory of initial lesson responses greater under delayed feedback than under immediate feedback. Also, instructional feedback effects varied depending on lesson item difficulty. The findings indicate that a connectionist model can explain instructional feedback effects.  相似文献   

A Standardized Generalized Dimensionality Discrepancy Measure and a Standardized Model‐Based Covariance for Dimensionality Assessment for Multidimensional Models          下载免费PDF全文

The standardized generalized dimensionality discrepancy measure and the standardized model‐based covariance are introduced as tools to critique dimensionality assumptions in multidimensional item response models. These tools are grounded in a covariance theory perspective and associated connections between dimensionality and local independence. Relative to their precursors, they allow for dimensionality assessment in a more readily interpretable metric of correlations. A simulation study demonstrates the utility of the discrepancy measures’ application at multiple levels of dimensionality analysis, and compares them to factor analytic and item response theoretic approaches. An example illustrates their use in practice.  相似文献

Role of Common Biochemical Markers for the Assessment of Fracture Union     

Mukhopadhyay M  Sinha R  Pal M  Bhattacharyya S  Dan A  Roy MM 《Indian journal of clinical biochemistry : IJCB》2011,26(3):274-278

The progress of fracture union requires close monitoring. Whereas, clinical examination and radiographic studies assess the outcome, biochemical markers like serum alkaline phosphatase and urinary hydroxyproline reflect the actual status of bone resorption and bone formation over a short time frame. 36 patients of long bone fracture were randomly allocated for the study. When the patient reported to the Department of Orthopedics after fracture, serum and urinary samples were collected and X-ray of the affected part were taken. Subsequent samples were collected and X-ray taken just after management (either operative or conservative), after 3rd, 5th, 8th and 12th week, respectively after onset of fracture. According to the course of callus formation the patients were divided into two groups that progressed to proper union or malunion. The levels of serum alkaline phosphatase, urinary total and free hydroxyproline levels were measured and statistically analysed and compared. A statistically significant positive correlation between total urinary hydroxyproline excretion and serum alkaline phosphatase indicate progress towards satisfactory union. Thus, serial monitoring of biochemical markers of bone turnover can be used as an adjunct to clinical and radiological evidence of fracture healing.  相似文献
