Revisiting a year in the sand: An HPT‐style after‐action review     

Dana Tucker 《Performance Improvement》2012,51(8):42-47

This is a retrospective analysis of the performance of a large training program in a combat environment looked at through the lens of human performance technology. Van Tiem, Moseley, and Dessinger's performance improvement/HPT model and strategic, operational, and tactical levels are used to describe effective and ineffective applications of human performance technology in a complex, multinational operation. While some interventions or projects at the training center showed marked improvements in targeted areas, there were numerous opportunities to do even better work, and the ultimate analysis of the effectiveness of the training center remains to be determined.  相似文献   

Object Properties and Object Kind: Twenty-One-Month-Old Infants' Extension of Novel Adjectives   总被引：2，自引：1，他引：1  

Sandra R. Waxman  Dana B. Markow 《Child development》1998,69(5):1313-1329

Three experiments examined the conditions under which infants acquiring English succeed in mapping novel adjectives, applied ostensively to individual objects, to other objects with the same property (color or texture). Twenty-one-month-old infants were introduced to a target (e.g., a yellow object) and asked to choose between (1) a matching test object (e.g., a different yellow object) and (2) a contrasting test object (e.g., a green object). Infants hearing the target labeled with novel adjectives were more likely than those hearing no novel words to choose the matching test object. Infants also revealed an emerging distinction between novel adjectives and nouns. Finally, infants' expectation regarding the extension of adjectives appears to unfold within the support of a familiar basic-level category. Infants extended novel adjectives to the matching test object when all objects were all drawn from the same basic level category; they failed to do so when the objects were drawn from different basic level categories.  相似文献   

Estimating the Impact of Instructional Practices on Student Achievement in Science     

Clare E. Von Secker  Robert W. Lissitz 《科学教学研究杂志》1999,36(10):1110-1126

This study used a hierarchical linear model (HLM) to estimate direct and indirect effects of instructional practices recommended by the National Science Education Standards on individual achievement. Three pedagogical reforms—namely, providing more opportunities for laboratory inquiry, increasing emphasis on critical thinking, and reducing the amount of teacher‐centered instruction—were expected to account for variability in school mean achievement and explain why gender, racial‐ethnic status, and socioeconomic status have more influence on achievement of students in some schools than in others. Results suggest that whereas the instructional policies recommended by the authors of the Standards may be associated with higher achievement overall, they are equally likely to have the unintended consequence of contributing to greater achievement gaps among students with different demographic profiles. Theoretical expectations about the impact of instructional practices on academic excellence and equity require further evaluation. © 1999 John Wiley & Sons, Inc.

Measuring The Business Impact of E‐Learning: An Empirical Study     

Greg Wang  Robert Von Der Linn  Diane Foucar‐Szocki  Oris Griffin  Erin Sceiford 《Performance Improvement Quarterly》2003,16(3):17-30

This study fills a gap in the current HRD literature of return on investment (ROI) analysis of technology‐based learning interventions. Using a Type IV control group method as defined by Wang (2002), the study empirically analyzed and measured the learning effectiveness and the business impact of an e‐learning system implemented in General Electric Company. The e‐learning system under study demonstrated significant economic returns in regard to reduced learning response time and reduced project cycle time. The study shows that e‐learning, as a means of technology‐based HRD intervention, can be highly effective as a performance support learning mechanism, although the results also suggest that e‐learning alone is not sufficient to replace the traditional face‐to‐face learning platforms.  相似文献

This study examined the association of gestational diabetes mellitus (GDM), prenatal, and postnatal maternal depressive symptoms with externalizing, internalizing, and autism spectrum problems on the Preschool Child Behavior Checklist in 2379 children aged 4.12 ± 0.60 (48% female; 47% White, 32% Black, 15% Mixed Race, 4% Asian, <2% American Indian/Alaskan Native, <2% Native Hawaiian; 23% Hispanic). Data were collected from the NIH Environmental influences on Child Health Outcomes (ECHO) Program from 2009-2021. GDM, prenatal, and postnatal maternal depressive symptoms were each associated with increased child externalizing and internalizing problems. GDM was associated with increased autism behaviors only among children exposed to perinatal maternal depressive symptoms above the median level. Stratified analyses revealed a relation between GDM and child outcomes in males only.  相似文献
