Research on the effectiveness of homework provides ample evidence that homework has a positive effect on learning, particularly for secondary students. Unfortunately, the rate of consistent homework completion for students, with and without disabilities, is low. This study used a between‐groups design to examine the differential effectiveness of coaching, a self‐management intervention, compared with the local treatment‐as‐usual (homework center) on improving the homework completion of 50 middle school students (Grades 6 to 8) with and without disabilities who were having substantial difficulty with homework. Results indicated that both group coaching and homework center (treatment‐as‐usual) were effective in significantly decreasing homework problems, with no clear indication that one intervention was, overall, superior to the other. However, preliminary analyses suggest that these interventions might be differentially effective as a function of disability status. 相似文献

在发展中国家和一些有多种文化背景的发达国家里,民族数学已经获得了一定水平的发展动力。另一方面,起源于发达国家的批判性数学教育特别关注民族数学研究的批判性观点。在这种研究中,为了把民族数学和学校数学连接起来,并把它作为教育尝试,批判性数学教育和民族数学之间相辅相成的关系已被详细考虑。因此,为了通过互惠方式加强批判性本质和发展以民族数学为基础的数学教育,一个基础性的框架被建立。 相似文献

This study proposed a method for suppressing torques and consumed energy of manipulators considering an effect of inertial forces in order to achieve power-saved drive. The present paper describes the case that the start and end points of a work path of a manipulator are specified and the path between the points can be determined arbitrarily, which is so-called point-to-point (PTP) control. The proposed method determines both the initial pose of a manipulator and input motions of its joints so that the torque or consumed energy is suppressed. The input motion of the joint is expressed by a motion curve that indicates the time profiles of input displacements, velocities and accelerations. The proposed method determines the motion curve as a polynomial with appropriate coefficients. Those coefficients and their values are decided by a heuristic algorithm in order to suppress the input torques or consumed energy of a manipulator. The paper actually determines the power-saved drive motion of “PUMA560” by the proposed method and reveals its effectiveness. 相似文献

In this article, we focus on Chinese word segmentation by systematically incorporating non-local information based on latent variables and word-level features. Differing from previous work which captures non-local information by using semi-Markov models, we propose an alternative method for modeling non-local information: a latent variable word segmenter employing word-level features. In order to reduce computational complexity of learning non-local information, we further present an improved online training method, which can arrive the same objective optimum with a significantly accelerated training speed. We find that the proposed method can help the learning of long range dependencies and improve the segmentation quality of long words (for example, complicated named entities). Experimental results demonstrate that the proposed method is effective. With this improvement, evaluations on the data of the second SIGHAN CWS bakeoff show that our system is competitive with the state-of-the-art systems. 相似文献

In order to design and predict the dechlorination processes for remediating the halogenated aromatic compounds in the biobarrier system applied in situ,an anaerobic continuous-flow column was set up with the introduction of an enriched 2,4,6-trichlorophenol(TCP) reductive dechlorinating consortium.The fates of TCP and its metabolites were simulated according to the first-order sequential dechlorination kinetic model.The enriched TCP anaerobic dechlorinating consortium dechlorinated 100 μmol/L TCP to 4-chlorophenol(4-CP) via 2,4-dichlorophenol(DCP) in 10 d.The consortium was predominated with the phylum of Firmicutes and Bacteroidetes,based on the PCRdenaturing gradient gel electrophoresis(DGGE) analysis.After the consortium was applied to the column,the experimental data in the steady state were fitted by the least square method,and the first-order dechlorination kinetic constants from TCP to 2,4-DCP,from 2,4-DCP to 4-CP and from 4-CP to phenol,were 1.58 d-1,2.23 d-1 and 0.206 d-1,respectively.According to the fitting results,the required biobarrier width for the complete remediation of TCP,2,4DCP and 4-CP were 126 cm,130 cm and 689 cm,respectively.The dechlorination/degradation of 4-CP must be increased when the technology is applied to the real site. 相似文献

Youth athletes are known to be at high risk of musculoskeletal (MSK) injuries. Children in developed countries are increasingly adopting a sedentary lifestyle. Although some risk factors related to sports activities have been reported, the effect of lifestyle (i.e. screen time behaviour) on MSK pain in youth athletes is not well known. This study aimed to examine the association of game playing and TV viewing with MSK pain among youth athletes. A self-administered questionnaire was mailed to youth athletes belonging to the Miyagi Amateur Sports Association. The final study population included 6,143 youth athletes (male, 71.1%; age range, 6–15 years). Multiple logistic regression analysis was used to examine the association of game playing and TV viewing behaviour with MSK pain. The point prevalence of MSK pain was 25.5%. The longest category of game playing time (≥3 h) was significantly associated with MSK pain as compared with the shortest category (<1 h) (odds ratio, 1.39; 95% confidence interval, 1.12–1.73, p = 0.003). There was no significant association between TV viewing time and MSK pain. These results suggest that game playing time might be an associated factor for MSK pain among youth athletes. 相似文献

ABSTRACTThe purpose of this study was to investigate the effects of slope on three-dimensional running kinematics at high speed. Thirteen male sprinters ran at high speed (7.5 m/s) on a motorised treadmill in each a level and a 5.0% slope condition. Three-dimensional motion analysis was conducted to compare centre of mass (CoM) energetics, pelvis segment and lower limb joints kinematics. We found that contact time was not affected by the slope, whereas flight time and step length were significantly shorter in uphill compared to level running. Uphill running reduced negative CoM work and increased positive CoM work compared to level running. Ankle, knee and hip joints were more flexed at initial ground contact, but only the knee was more extended at the end of stance in uphill compared to level running. Additionally, the hip joint was more abducted, and the free leg side of the pelvis was more elevated at the end of stance in uphill running. Our results demonstrate that joint motion must be developed from a more flexed/adducted position at initial contact through a greater range of motion compared to level running in order to meet the greater positive CoM work requirements in uphill running at high speed. 相似文献
