The use of teacher praise in the classroom has been the subject of empirical research since the 1970s, but despite more than four decades of research on the use of teacher praise, large gaps continue to exist in the literature. Clarifying the role and benefit of teacher praise is particularly important because the use of positive, proactive strategies is promoted by large‐scale behavior initiatives (e.g., Positive Behavior Interventions and Support). The goal of this review is to summarize the existing research on teacher praise, including rates of praise, types of praise, and the association between praise and student behavior. In addition to summarizing the extant literature, future directions for research are highlighted. This review reveals that there is a need for current, large‐scale studies with consistent operational definitions that measure the rate of different types of praise across different grades and instructional activities, while simultaneously measuring student behavioral outcomes. 相似文献

Researchers examined whether a parent-implemented language intervention improved problem behaviors 1 year after intervention. Ninety-seven children with language delays (mean age at 12-month follow-up = 48.22 months) were randomized to receive Enhanced Milieu Teaching (EMT) language intervention or business as usual treatment. Twelve months after the intervention ended, children in the EMT intervention condition displayed lower rates of parent-reported externalizing, internalizing, and total problem behaviors. A mediation analysis revealed that the relation between EMT and problem behaviors was partially mediated by child rate of communication for both internalizing and total problem behaviors. A developmental framework is proposed to explain the impact of EMT on problem behaviors, and future lines of research are discussed. 相似文献

We investigated narcissism as a moderator of social loafing on a physical performance task. High and low narcissistic individuals twice performed a cycling task in same-sex teams of three: once when identifiability was low; and once when identifiability was high. A significant interaction between narcissism and identifiability was revealed, F(1, 40) = 4.09, p < .05, eta2 = .09 for performance. Follow-up tests indicated that high narcissists' performance significantly increased with greater identifiability, whereas low narcissists displayed no such performance differences. Results suggested that this effect was due to an increase in narcissists' on-task effort (ratings of perceived exertion and heart rate) when they knew that their performance was to be identified. 相似文献

Modern-day cricket has experienced a shift towards limited over games, where the emphasis is on scoring runs at a rapid rate. Although the use of protective equipment in cricket is mandatory, players perceive that leg guards, in particular, can restrict their motion. The aim of this study was to determine the influence of cricket leg guards on running performance. Initial testing revealed that wearing pads significantly increased the total time taken to complete three runs by up to 0.5?s compared with running without pads (P?0.05). In addition, we found that the degree of impedance was dependent on pad design and could not be solely attributed to additional weight. To assess possible causes of reduced running performance, a biomechanical analysis was performed, investigating running kinematics, stride parameters, and ground reaction forces. The results revealed that the widest pad had the greatest effect on running kinematics, increasing hip abduction and decreasing hip extension, resulting in a shortened stride length (by 0.10?m) and increased stride width (by 0.12?m) compared with running without pads. Wearing pads also significantly increased peak braking force (by up to 0.3 times body weight [BW]), braking impulse (by up to 0.012 BW?·?s(-1)), peak mediolateral force (by up to 0.17 BW), and mediolateral impulse (by up to 0.016 BW?·?s(-1)) compared with running without pads, which resulted in reduced force applied in the direction of locomotion. The consequence of this reduction in running performance is an increased risk of being run-out or a reduction in the number of runs that could be scored from a particular shot. 相似文献
