Web 2.0 and Transfer: Trainers' Use of Technology to Support Employees' Learning Transfer on the Job
Andrea J. Hester Holly M. Hutchins Lisa A. Burke‐Smalley 《Performance Improvement Quarterly》2016,29(3):231-255
We steer transfer research in a new direction by examining the use of Web 2.0 technologies for supporting learning transfer resulting from formal training. We report survey results from training professionals (N = 83) on how their organization uses such methods to cue and support workers’ application of learned knowledge and skills on the job. Guided by the technology acceptance model (TAM) theory, we examined predictor variables found to influence technology use based on empirical and theoretical support in the information technology (IT) literature. Results indicate that trainers are influenced by several individual factors (computer experience, computer anxiety, and computer self‐efficacy), as well as their organization's learning climate, to use Web 2.0 tools to support transfer of learning. Trainers also prefer to use social media, networking applications, and visual media to support transfer among learners. We discuss implications for using Web 2.0 technologies in support of learning transfer and provide directions for future workplace learning research. 相似文献

A spiral inertial filtration (SIFT) device that is capable of high-throughput (1 ml/min), high-purity particle separation while concentrating recovered target particles by more than an order of magnitude is reported. This device is able to remove large fractions of sample fluid from a microchannel without disruption of concentrated particle streams by taking advantage of particle focusing in inertial spiral microfluidics, which is achieved by balancing inertial lift forces and Dean drag forces. To enable the calculation of channel geometries in the SIFT microsystem for specific concentration factors, an equivalent circuit model was developed and experimentally validated. Large particle concentration factors were then achieved by maintaining either the average fluid velocity or the Dean number throughout the entire length of the channel during the incremental removal of sample fluid. The SIFT device was able to separate MCF7 cells spiked into whole blood from the non-target white blood cells (WBC) with a recovery of nearly 100% while removing 93% of the sample volume, which resulted in a concentration enhancement of the MCF7 cancer cells by a factor of 14. 相似文献

In this work, we introduce a method for the soft-lithography-based fabrication of rigid microstructures and a new, simple bonding technique for use as a continuous-flow cell lysis device. While on-chip cell lysis techniques have been reported previously, these techniques generally require a long on-chip residence time, and thus cannot be performed in a rapid, continuous-flow manner. Microstructured microfluidic devices can perform mechanical lysis of cells, enabling continuous-flow lysis; however, rigid silicon-based devices require complex and expensive fabrication of each device, while polydimethylsiloxane (PMDS), the most common material used for soft lithography fabrication, is not rigid and expands under the pressures required, resulting in poor lysis performance. Here, we demonstrate the fabrication of microfluidic microstructures from off-stoichiometry thiol-ene (OSTE) polymer using soft-lithography replica molding combined with a post-assembly cure for easy bonding. With finite element simulations, we show that the rigid microstructures generate an energy dissipation rate of nearly 107, which is sufficient for continuous-flow cell lysis. Correspondingly, with the OSTE device we achieve lysis of highly deformable MDA-MB-231 breast cancer cells at a rate of 85%, while a comparable PDMS device leads to a lysis rate of only 40%. 相似文献

The study compared differences and similarities between WISC and WISC-R scores for 48 ten- and thirteen-year-old EMR students, who were matched according to sex and race. The WISC-R yielded significantly lower VS, PS, and FS IQ scores than the WISC for this predominantly rural Georgia population. The FS IQ scores from the WISC-R averaged 7.5 points lower than the WISC FS IQs, with similar differences noted for VS and PS scores. There was no significant difference in FS IQs between the two age groups. Results suggest that many children classified as “Borderline” or slightly above by the WISC will be classified as “Mentally Deficient” by the WISC-R. 相似文献

Important problems exist in the field of communications theory whose solution is in the form of an expectation of a function of a random variable. Often it is not computationally feasible to evaluate these moments exactly. This paper presents a geometric bounding technique that yields tight upper and lower bounds to generalized moments of a broad class of random variables. This technique produces excellent results for these communications theory problems. 相似文献

Research Findings: This study investigated the joint influence of maternal cognitive readiness to parent and children's self-esteem on children's academic achievement and behavioral adjustment in the classroom at age 10. Participants were 153 adolescent mothers and their firstborn children. Findings indicated that low levels of prenatal maternal cognitive readiness to parent were associated with impairments in children's achievement and adjustment at age 10, regardless of the children's level of self-esteem. Among dyads in which mothers were more cognitively prepared for the parenting role, however, children with higher self-esteem showed notably better achievement and adjustment compared to those with lower self-esteem. These results illustrate the joint influence of mothers' preparedness for parenting and children's self-esteem on the school performance of children who are generally considered to be at high risk for impairments in achievement and adjustment. Practice or Policy: Findings are discussed in terms of the enduring impact of cognitive readiness to parent and self-esteem on the academic achievement and behavioral adjustment of at-risk children, with a focus on implications for intervention and prevention based on the specific findings from this study. 相似文献

The research reported in this paper investigates why teachers in regional primary schools in the Ballarat region of Victoria, Australia, are choosing to outsource the teaching of sexuality education. A survey was conducted of 29 Year 5 and Year 6 teachers from local primary schools. The teachers provided information about: their confidence in delivering sexuality-related topics; their perceptions of the relevance of given sexuality topics to their students; the teachers' own professional development preferences; and what they saw as their personal limitations in teaching sexuality education. Teachers tended to report low confidence in teaching topics that are considered ‘sensitive’, such as menstruation, wet dreams and sexual intercourse. Furthermore, they indicated a need for professional development in teaching sexuality education. The greatest hurdle identified lies in identifying how to motivate, engage and support teachers to take a professional interest in teaching sexuality education. 相似文献

“FRIENDS for Life” is a cognitive behavioural therapy (CBT) programme which aims to reduce anxiety and promote resilience among children. This study evaluated the “FRIENDS for Life” (FRIENDS) programme used as an intervention for seven children between the ages of 10 and 11 presenting with high functioning autism spectrum disorder (HFA) who attend mainstream schooling. The study adopts a mixed methodology, explanatory research design, which included pre- and post-quantitative anxiety scales, parental interviews completed post-intervention, narrative observation of FRIENDS sessions and a post-intervention children’s evaluation questionnaire. Quantitative findings from this study suggest that participation in the “FRIENDS” programme does not reduce anxiety levels to promote resilience. Such results are discussed with regard to the utility of using standardised self-report measures among children with HFA. Despite this, qualitative information indicates that “FRIENDS” can be made accessible for children with HFA. Recommendations and implications for future research and FRIENDS implementations are outlined. 相似文献
