This study examined a theoretical model hypothesizing that reading strategies mediate the effects of intrinsic reading motivation, reading fluency, and vocabulary knowledge on reading comprehension. Using path analytic methods, we tested the direct and indirect effects specified in the hypothesized model in a sample of 1105 fifth-graders. In addition to standardized tests and questionnaires, we administered a performance test to assess students' proficiency in the application of three reading strategies. The overall fit of the model to the data was good. Both cognitive (fluency and vocabulary) and motivational (intrinsic reading motivation) variables had an indirect effect on reading comprehension through their influence on reading strategies. Reading strategies had a unique effect on reading comprehension and partially mediated the effects that cognitive and motivational variables had on fifth-graders' reading achievements. 相似文献

We tested a simple and compact device designed for manual resistance training in conditions of microgravity (Self-Powered Rope Trainer Duo (SPoRT Duo)) to increase muscle performance. Twenty-four participants (20.8 ± 2.1 years) were randomly assigned to a manual resistance group (n = 12) and a free-weight group (n = 12). Participants performed eight exercises (three sets; 8–12 efforts) either with free weights or the SPoRT Duo twice a week for 6 weeks. Maximal isometric force of trunk flexion, back extension and chest press increased (P at least 0.01, d at least 0.52) both in the manual resistance group (18.4% ± 15.0%; 32.7% ± 22.7%; 15.3% ± 9.7%) and free-weight group (18.0% ± 13.9%; 26.6% ± 28.9%; 13.3% ± 7.6%). The change in maximal isometric force of wide grip row in both groups (d at best 0.38) did not reach statistical significance (P at best 0.08). The squat one-repetition-maximum increased in the manual resistance group (29.8% ± 22.1%) and the free-weight group (32.4% ± 26.6%). Jump height, determined by a jump-and-reach test, increased in the free-weight group (9.8% ± 13.2%) but not in the manual resistance group (2.0% ± 8.5%). Manual resistance training was equally effective in increasing strength as traditional resistance training with free weights. This apparatus is a useful addition to current in-flight exercise systems. 相似文献

This article gives a report on a recent empirical study on cooperative religious education in German primary schools. Special emphasis is given to the views, needs, and rights of children. Results from interviews with the children and with the teachers as well as from classroom observation form the basis for the authors' suggestions concerning the future shape of religious education. 相似文献

OBJECTIVES: This study was designed to assess the incidence of child emotional and physical abuse, associated risk factors and psychosocial symptoms in a cross-cultural comparison between post-communist bloc countries. Method: One-thousand one-hundred forty-five children ages 10-14 from Latvia (N = 297), Lithuania ( N = 300), Macedonia (N = 302), and Moldova (N = 246) participated in the study. They completed questionnaires assessing their experience of emotional or physical abuse, and provided information about family risk-factors and psychosocial symptoms, including PTSD-related symptoms. RESULTS: Incidence rates of maltreatment differed by country, as did levels of reported psychosocial symptoms. Incidence of emotional and physical abuse differed by region, with higher levels of abuse reported in the rural regions. In all four countries, a similar association between emotional/physical abuse and psychosocial symptoms was found, with the uniformly largest correlation between emotional abuse and anger. When examining the combined scores of emotional and physcial abuse, even higher correlation's were found, particularly in relation to anger and depression. In all four countries, parental overuse of alcohol was associated with emotional and/or physical abuse. CONCLUSIONS: Findings show differences by country in child-reported levels of emotional and physical abuse, but similar patterns of correlation with psychosocial symptoms and the risk factors of parental alcohol overuse and living in a rural area. 相似文献
