Research has shown that various individual factors play an important role in the underachievement of gifted students. Most often discussed as predictors of underachievement are motivation, learning behavior, and emotions. To examine which specific constructs from these fields simultaneously predict underachievement among gifted fourth graders, logistic regression was performed on data from eighty-five highly intelligent students out of thirty-four classrooms. Students reported on their self-efficacy, learning goal orientation, use of text-reduction strategies, anxiety, boredom, anger, and enjoyment. Emerging predictors of underachievement were self-efficacy, use of text-reduction strategies, and anxiety. As these constructs are all connected to self-regulated learning in different ways, an intervention was implemented which successfully encourages self-regulated learning among students of differing cognitive abilities. Assessing the intervention’s effectiveness for different ability levels was important as the intervention was not a pull-out program, but was integrated into regular classroom instruction in which all students in these classes participated. Results from multilevel longitudinal models showed positive intervention effects for learning behavior among gifted underachievers, but no intervention effects on self-efficacy and anxiety could be detected.  相似文献

Doping and antidoping are socially constructed, evolving and historically contingent phenomena relying on actors agreeing about allowed and deviant behaviour. Therefore, public discourse about doping represents an important part of the history of doping and antidoping. Content analysis of doping discourse in German quality media Der Spiegel und Die Zeit in the 1950s and 1960s shows that public attention for doping was rather low even though awareness increased due to the politicisation of sport and the rise of anabolic doping. Doping does not appear as a particular pressing but solvable problem. Moreover, doping is not linked to West German sport. In ethical terms, doping is perceived negatively. Neither does there exist a general mistrust in the sport bodies nor are sport bodies or sport policy clearly and resolutely requested to act. Therefore, the well-known 1969 article by Brigitte Berendonk marks a qualitative turn in public doping discourse.  相似文献

ABSTRACT

The football goalkeeper position arguably represents a unique role within the team sport. Despite its highly complex skill demands, research on football goalkeeping has only sporadically examined the position within isolated and limited parameters. In particular, there is limited literature on “modern” skill acquisition training methods and approaches within the field of goalkeeper training. In a cross-cultural study with fifteen expert goalkeeper coaches, researchers here examined the overarching research question of “how does the modern football goalkeeper train?”. Semi-structured interviews explored expert coaches’ views on critical skills for performance in goalkeeping and the training approaches used to develop these critical skills. Results indicate that four skill sets are considered essential by goalkeeper coaches, these are: decision-making skills, athleticism, mentality, and technical skills. In terms of developing these skills in goalkeeper-specific training, the majority of expert coaches apply a similar microstructure to training sessions. This structure involves a steady progression from simple to complex training tasks, where for large parts, isolated technical training appears to be prioritised over a holistic training approach that integrates technical skills and perceptual-cognitive components (e.g., decision making). Scientific and practical recommendations for researchers and practitioners in the field of football goalkeeper coaching are provided.  相似文献

The Library Outreach Program Committee at Western Washington University serves as a coordinating body for outreach activities to the non-departmental campus community. Successful projects include collaboration with New Student Services/Family Outreach, Academic User Technology Services, and Residential Life. A database of outreach activities assists in tracking and assessing outreach activities.  相似文献

Circulating tumor cells (CTCs) are important biomarkers for monitoring tumor dynamics and efficacy of cancer therapy. Several technologies have been demonstrated to isolate CTCs with high efficiency but achieve a low purity from a large background of blood cells. We have previously shown the ability to enrich CTCs with high purity from large volumes of blood through selective capture in microvortices using the Vortex Chip. The device consists of a narrow channel followed by a series of expansion regions called reservoirs. Fast flow in the narrow entry channel gives rise to inertial forces, which direct larger cells into trapping vortices in the reservoirs where they remain circulating in orbits. By studying the entry and stability of particles following entry into reservoirs, we discover that channel cross sectional area plays an important role in controlling the size of trapped particles, not just the orbital trajectories. Using these design modifications, we demonstrate a new device that is able to capture a wider size range of CTCs from clinical samples, uncovering further heterogeneity. This simple biophysical method opens doors for a range of downstream interventions, including genetic analysis, cell culture, and ultimately personalized cancer therapy.  相似文献

In this study, we examined whether gendered discourse styles were evidenced in online, synchronous, physics collaborative learning group discussions, and the extent to which such discourse patterns were related to the uptake of ideas within the group. We defined two discourse styles: the oppositional/direct style, theorized to be the socialized discourse pattern typically used by males, and the aligned/indirect style, theorized to be the socialized discourse pattern typically used by females. Our analysis indicates the presence of both styles in these chats and the styles were generally utilized along theorized, gendered lines. However, we also observed male use of the stereotypically ‘feminine' discourse style and female use of the stereotypically ‘masculine' discourse style. Moreover, we found no main effect for discourse style on the uptake of ideas. The findings indicate that, contrary to prior research in both face-to-face science classroom settings and online physics settings, ideas were taken up at relatively similar rates regardless of the gendered discourse style employed. Design implications of this study are discussed and suggestions for future research are made.  相似文献

Interpersonal neural synchrony (INS) has been previously evidenced in mother–child interactions, yet findings concerning father–child interaction are wanting. The current experiment examined whether fathers and their 5- to 6-year-old children (N = 66) synchronize their brain activity during a naturalistic interaction, and addressed paternal and child factors related to INS. Compared to individual problem solving and rest, father–child dyads showed increased INS in bilateral dorsolateral prefrontal cortex and left temporo-parietal junction during cooperative problem solving. Furthermore, the father’s attitude toward his role as a parent was positively related to INS during the cooperation condition. These results highlight the implication of the father’s attitude to parenting in INS processes for the first time.  相似文献
