Engaging client groups differently: A standardized approach to performance improvement     

Timothy E. LaMacchio 《Performance Improvement》2009,48(9):18-24

Moving clients past counterproductive approaches to improving performance requires performance improvement (PI) professionals to work differently. They must collaboratively engage clients in anticipating and solving problems. It calls for a user‐friendly and explicit PI process that drives results. This proactive engagement promotes a shared view and language of the PI process. It enables PI professionals and clients to work jointly with common tools to improve performance, make everyday decisions, and achieve business results.  相似文献   

Children’s Eyewitness Memory for Multiple Real‐Life Events     

Timothy N. Odegard  Crystal M. Cooper  James M. Lampinen  Valerie F. Reyna  Charles J. Brainerd 《Child development》2009,80(6):1877-1890

The present research examined the influence of prior knowledge on children’s free recall, cued recall, recognition memory, and source memory judgments for a series of similar real‐life events. Forty children (5–12 years old) attended 4 thematic birthday parties and were later interviewed about the events that transpired during the parties using the National Institute of Child Health and Human Development protocol. Of the events, half were generic in that they could have occurred at any birthday party, and half were specific to the theme of the party. Older children demonstrated more evidence of using gist‐based information to guide their memory performance than did younger children. However, younger children were able to use global gist to inform their source memory judgments, qualifying past word‐learning research.  相似文献   

Explorable three‐dimensional digital model of the female pelvis,pelvic contents,and perineum for anatomical education     

Aimée Sergovich  Marjorie Johnson  Timothy D. Wilson 《Anatomical sciences education》2010,3(3):127-133

The anatomy of the pelvis is complex, multilayered, and its three‐dimensional organization is conceptually difficult for students to grasp. The aim of this project was to create an explorable and projectable stereoscopic, three‐dimensional (3D) model of the female pelvis and pelvic contents for anatomical education. The model was created using cryosection images obtained from the Visible Human Project, in conjunction with a general‐purpose three‐dimensional segmentation and surface‐rendering program. Anatomical areas of interest were identified and labeled on consecutive images. Each 2D slice was reassembled, forming a three‐dimensional model. The model includes the pelvic girdle, organs of the pelvic cavity, surrounding musculature, the perineum, neurovascular structures, and the peritoneum. Each structure can be controlled separately (e.g. added, subtracted, made transparent) to reveal organization and/or relationships between structures. The model can be manipulated and/or projected stereoscopically to visualize structures and relationships from different angles with excellent spatial perception. Because of its ease of use and versatility, we expect this model may provide a powerful teaching tool for learning in the classroom or in the laboratory.

Increased Implementation of Emergent Literacy Screening in Pre-Kindergarten     

Marcia Invernizzi  Timothy J. Landrum  Avery Teichman  Monika Townsend 《Early Childhood Education Journal》2010,37(6):437-446

The recent emphasis on universal prekindergarten programs, coupled with ongoing concern about children’s’ early literacy development in the first years of school, carry significant implications for how preschool educators program for literacy and assess literacy growth. We discuss the evolving role of literacy development in expanded preschool, examine key features of literacy assessments with particular attention to the content that might be assessed in preschool, and provide as an example one preschool literacy assessment tool that is in widespread use in the United States. We discuss the policy and practice implications of the growing emphasis on literacy assessment in preschoolers.  相似文献   

Stratified and Maximum Information Item Selection Procedures in Computer Adaptive Testing     

Hui Deng  Timothy Ansley  Hua-Hua Chang 《Journal of Educational Measurement》2010,47(2):202-226

In this study we evaluated and compared three item selection procedures: the maximum Fisher information procedure (F), the a-stratified multistage computer adaptive testing (CAT) (STR), and a refined stratification procedure that allows more items to be selected from the high a strata and fewer items from the low a strata (USTR), along with completely random item selection (RAN). The comparisons were with respect to error variances, reliability of ability estimates and item usage through CATs simulated under nine test conditions of various practical constraints and item selection space. The results showed that F had an apparent precision advantage over STR and USTR under unconstrained item selection, but with very poor item usage. USTR reduced error variances for STR under various conditions, with small compromises in item usage. Compared to F, USTR enhanced item usage while achieving comparable precision in ability estimates; it achieved a precision level similar to F with improved item usage when items were selected under exposure control and with limited item selection space. The results provide implications for choosing an appropriate item selection procedure in applied settings.  相似文献

A comparison of the agreement,internal consistency,and 2-day test stability of the InBody 720, GE iDXA,and BOD POD® gold standard for assessing body composition     

Bruce W Bailey  Gabrielle LeCheminant  Timothy Hope  Mathew Bell  Larry A Tucker 《Measurement in physical education and exercise science》2018,22(3):231-238

The study compared the agreement, internal consistency, and measurement stability of the GE iDXA, BOD POD, and InBody 720. Body composition of 43 men and 37 women (31.4 ± 10.7 years; 90% Caucasian and 10% other) was assessed in triplicate using each method over two different days. Mean percent body fat (% BF) of the participants was different for all three machines (27.6 ± 10.0% [GE iDXA)] 25.6 ± 10.4% [BOD POD], and 21.3 ± 10.6% [InBody 720]; p < .05). The coefficient of variation for same day repeated measures was 1.06% (GE iDXA), 3.29% (BOD POD), and 2.97% (InBody 720). The coefficient of variation for 2-day repeated measures was 1.81% (GE iDXA), 4.61% (BOD POD), and 4.24% (InBody 720). The difference between the GE iDXA and BOD POD was within acceptable variability, while the InBody 720 significantly underestimated % BF. The internal consistency was highest for the GE iDXA, followed by the InBody 720, and then the BOD POD.  相似文献   

Associations Between Sexting Behaviors and Sexual Behaviors Among Mobile Phone‐Owning Teens in Los Angeles          下载免费PDF全文

The implications of teen sexting for healthy development continue to concern parents, academics, and the general public. Using a probability sample of high school students (N = 1,208) aged 12–18, the prevalence of sexting, associations with sexting, and associations between sexing and sexual activity were assessed. Seventeen percent both sent and received sexts, and 24% only received sexts. Sending and receiving sexts were positively associated with each other and both behaviors were associated with having peers who sext. Lifetime reports of sexual intercourse, anal sex, oral sex, and recent unprotected sex were positively associated with reports of texting 300 or more times per day, only receiving sexts, and both sending and receiving sexts.  相似文献   

An intensification approach to double-block algebra: A pilot implementation of Intensified Algebra in a large urban school district     

Simon T. Tidd  Timothy M. Stoelinga  Angela M. Bush-Richards  Donna L. De Sena  Theodore J. Dwyer 《The Journal of educational research》2018,111(1):95-107

Double-block instruction has become a popular strategy for supporting struggling mathematics students in algebra I. Despite its widespread adoption, little consistent evidence supports the attributes of a successful double-block design or the effectiveness of this instructional strategy. In this study, the authors examine a pilot implementation of a double-block strategy—instantiated in the program Intensified Algebra—that combines core algebra content with insights from research on how students learn mathematics and explicit noncognitive supports focused on key attitudes, beliefs, and behaviors essential to student success. The results of the study show that, when implemented with fidelity, participation in the program significantly increased student achievement on the state end-of-course algebra I assessment.  相似文献   

Effect of a randomised 12-week resistance training programme on muscular strength,cross-sectional area and muscle quality in women having undergone Roux-en-Y gastric bypass

The purpose of this study was to examine the effect of a 12-week resistance training programme on fat-free mass (FFM), muscle cross-sectional area, muscular strength and muscle quality in women who underwent Roux-en-Y gastric bypass surgery. Participants were 16 women (mean age = 44.9 ± 10.2 years) from bariatric surgical groups who were randomly assigned into either a control or an intervention group. Air displacement plethysmography measured FFM and magnetic resonance imaging measured quadriceps muscle cross-sectional area and whole thigh muscle cross-sectional area. Muscular strength and quality was assessed using an estimated 1-Repetition Maximum assessment. All measurements were collected twice, at baseline and at a 12-week follow-up. There were significantly greater improvements in leg press strength (mean differences = 55.4%, P < 0.001, Cohen’s d = 2.4), leg extension strength (mean differences = 18.0%, P = 0.014, Cohen’s d = 0.86) and leg press muscle quality (mean differences = 54.5%, P < 0.001, Cohen’s d = 1.9) in the intervention group compared to the control group following the resistance training programme. The resistance training intervention significantly improved muscular strength and quality; however, it did not illicit changes in FFM or muscle cross-sectional area in women who underwent Roux-en-Y gastric bypass surgery.  相似文献
