ABSTRACT

The systematic review and meta-analysis evaluated the effect of aerobic, resistance and combined exercise on RMR (kCal·day^-1) and performed a methodological assessment of indirect calorimetry protocols within the included studies. Subgroup analyses included energy/diet restriction and body composition changes. Randomized control trials (RCTs), quasi – RCTs and cohort trials featuring a physical activity intervention of any form and duration excluding single exercise bouts were included. Participant exclusions included medical conditions impacting upon RMR, the elderly (≥65 years of age) or pregnant, lactating or post-menopausal women. The review was registered in the International Prospective Register of Systematic Reviews (CRD 42,017,058,503). 1669 articles were identified; 22 were included in the qualitative analysis and 18 were meta-analysed. Exercise interventions (aerobic and resistance exercise combined) did not increase resting metabolic rate (mean difference (MD): 74.6 kCal·day^-1[95% CI: ?13.01, 161.33], P = 0.10). While there was no effect of aerobic exercise on RMR (MD: 81.65 kCal·day^-1[95% CI: ?57.81, 221.10], P = 0.25), resistance exercise increased RMR compared to controls (MD: 96.17 kCal·day^-1[95% CI: 45.17, 147.16], P = 0.0002). This systematic review effectively synthesises the effect of exercise interventions on RMR in comparison to controls; despite heterogenous methodologies and high risk of bias within included studies.  相似文献

Reading to Learn or Learning to Read? Engaging College Students in Course Readings     

Mary Margaret Kerr  Kristen M. Frese 《College Teaching》2017,65(1):28-31

Despite instructors' belief that class readings are integral to the learning process, only 20–30% of undergraduate students complete required readings. Failure to complete course reading has been associated with declines in exam and research performance. This article first offers a brief review of the literature on why students do not complete course readings: 1) unpreparedness, 2) lack of motivation, 3) time constraints, and 4) an underestimation of reading importance. We then identify approaches that encourage students to read, enjoy reading, and develop metacognitive knowledge, shown to improve learning.  相似文献   

Using Student Video Cases to Assess Pre-service Elementary Teachers’ Engineering Teaching Responsiveness     

Tejaswini?DalviEmail author  Kristen?Wendell 《Research in Science Education》2017,47(5):1101-1125

Our study addresses the need for new approaches to prepare novice elementary teachers to teach both science and engineering, and for new tools to measure how well those approaches are working. This in particular would inform the teacher educators of the extent to which novice teachers are developing expertise in facilitating their students’ engineering design work. One important dimension to measure is novice teachers’ abilities to notice the substance of student thinking and to respond in productive ways. This teacher noticing is particularly important in science and engineering education, where students’ initial, idiosyncratic ideas and practices influence the likelihood that particular instructional strategies will help them learn. This paper describes evidence of validity and reliability for the Video Case Diagnosis (VCD) task, a new instrument for measuring pre-service elementary teachers’ engineering teaching responsiveness. To complete the VCD, participants view a 6-min video episode of children solving an engineering design problem, describe in writing what they notice about the students’ science ideas and engineering practices, and propose how a teacher could productively respond to the students. The rubric for scoring VCD responses allowed two independent scorers to achieve inter-rater reliability. Content analysis of the video episode, systematic review of literature on science and engineering practices, and solicitation of external expert educator responses establish content validity for VCD. Field test results with three different participant groups who have different levels of engineering education experience offer evidence of construct validity.  相似文献   

CSRP's Impact on low-income preschoolers' preacademic skills: self-regulation as a mediating mechanism     

Raver CC  Jones SM  Li-Grining C  Zhai F  Bub K  Pressler E 《Child development》2011,82(1):362-378

Based on theoretically driven models, the Chicago School Readiness Project (CSRP) targeted low-income children's school readiness through the mediating mechanism of self-regulation. The CSRP is a multicomponent, cluster-randomized efficacy trial implemented in 35 Head Start-funded classrooms (N = 602 children). The analyses confirm that the CSRP improved low-income children's self-regulation skills (as indexed by attention/impulse control and executive function) from fall to spring of the Head Start year. Analyses also suggest significant benefits of CSRP for children's preacademic skills, as measured by vocabulary, letter-naming, and math skills. Partial support was found for improvement in children's self-regulation as a hypothesized mediator for children's gains in academic readiness. Implications for programs and policies that support young children's behavioral health and academic success are discussed.  相似文献   

Double jeopardy: poorer social-emotional outcomes for children in the NICHD SECCYD experiencing home and child-care environments that confer risk   总被引：1，自引：0，他引：1  

Watamura SE  Phillips DA  Morrissey TW  McCartney K  Bub K 《Child development》2011,82(1):48-65

Using data from the National Institute of Child Health and Human Development Early Child Care Research Network (NICHD SECCYD), the authors examined whether interactions between home and child-care quality affect children's social-emotional adjustment at 24, 36, and 54 months (N = 771). Triadic splits on quality of home and child care were used to examine children in specific ecological niches, with a focus on those who experience the double jeopardy of poor quality home and child-care environments. Children in this niche exhibited the highest levels of mother-reported problem behavior and the lowest levels of prosocial behavior. However, there was evidence that children from lower quality home environments were able to benefit from the compensatory influence of high-quality child care. These results suggest policies aimed at the cross-context influences of protective and risky settings.  相似文献   

A real world comparison of the effectiveness of satellite training and classroom training     

Deborah L. Whetzel  Daniel B. Felker  Kristen M. Williams 《Educational technology research and development : ETR & D》1996,44(3):5-18

Businesses and educational institutions use satellite technology to transmit information for a number of purposes, including training. This study assessed the effectiveness of a satellite training program for achieving various learning requirements ranging from recognition and recall of information to the performance of a specific job procedure. This study also compared satellite training with traditional classroom training for two courses in which the same material was taught using both media. Results showed that learning occurred using the satellite medium and that there were slight but statistically significant differences between satellite and classroom instruction for learning job-related skills.Kristen M. Williams is a senior member of AIR's research staff specializing in training research and evaluation. The research reported here was conducted under Contract Number 104230-88-D-1811, Task Order Number 10430-92-D-1296 with the United States Postal Service.

Childbirth Education for the HIV-Positive Woman     

Montgomery KS 《The Journal of perinatal education》2003,12(4):16-26

Pregnant HIV-positive women have unique education needs during the perinatal period. HIV-positive women need information regarding the differences in recommended care they can expect to experience both for themselves and their newborn. Differences in recommended care are related to minimizing transmission of the HIV virus. This article discusses the unique educational content needs of HIV-positive pregnant women. Providing women with appropriate information about what their labor and delivery experiences will entail can help them make decisions and promote a positive birth experience.  相似文献   

The existence and extent of spatial working memory ability in honeybees     

Michael F. Brown  Jonathan A. Moore  Catherine H. Brown  Kristen D. Langheld 《Learning & behavior》1997,25(4):473-484

Honeybees foraged from six locations, each of which was baited with sugar solution prior to each experimental trial. Under a variety of conditions, bees exhibited a small but reliable tendency to avoid revisits to locations that they had visited earlier during the experimental trial. These results replicate those of Brown and Demas (1994), who concluded that bees use working memory to discriminate previously visited locations from those not yet visited. The present experiments included procedures that allowed alternatives to this explanation to be more completely ruled out. The extent of spatial working memory performance exhibited by honeybees in these experiments appears to be limited by a process other than working memory capacity, perhaps the ability of bees to discriminate among several locations in close proximity to one another.  相似文献
