Neuroscientific knowledge has undeniably gained interest among educators worldwide. However, not all “brain facts” believed by teachers are supported by science. This study sought to evaluate the belief in these so‐called neuromyths among 3,451 Latin American teachers. We found that, consistent with prior research among teachers in other geographic areas, teachers in Latin America hold major misconceptions about neuroscience, especially as it relates to factual information about its structure and functioning. Differences across South American nations were observed with moderate and slight effect sizes for general knowledge of the brain and neuromyths, respectively. Teachers working in higher education had slightly superior performance. Teachers at all levels who reported knowing more about the brain, however, were more likely to believe invalid assertions known as neuromyths. These results shed light on trends in the field of education, hoping to encourage the development of strategies aimed at correcting the use of science as it relates to education. The implications regarding teaching practice, policy, and teacher training are discussed. 相似文献

Abstract In this study, we examined the effects of relative positioning of attacker-defender dyads to the basket on interpersonal coordination tendencies in basketball. To achieve this aim, four right-hand dominant basketball players performed in a 1 vs. 1 sub-phase, at nine different playing locations relative to the basket (from 0° to 180°, in 20° increments). Performers' movement displacement trajectories were video-recorded and digitized in 162 trials. Results showed that interpersonal coordination tendencies changed according to the scaling of the relative position of performers to the basket. Stable in-phase modes of coordination were observed between performers' longitudinal and lateral displacements (50.47% and 43.02%) on the left side of the court. On the right side of the court, a shift in the dominant mode of coordination was observed to a defender lead-lag of -30°, both for longitudinal and lateral displacements (30.51% and 32.65%). These results suggest how information about dribbler hand dominance and relative position to the basket may have constrained attacker-defender coordination tendencies in 1 vs. 1 sub-phases of basketball. 相似文献

In this paper we present the relevance ranking algorithm named PolarityRank. This algorithm is inspired in PageRank, the webpage relevance calculus method used by Google, and generalizes it to deal with graphs having not only positive but also negative weighted arcs. Besides the definition of our algorithm, this paper includes the algebraic justification, the convergence demonstration and an empirical study in which PolarityRank is applied to two unrelated tasks where a graph with positive and negative weights can be built: the calculation of word semantic orientation and instance selection from a learning dataset. 相似文献

George Kelly’s repertory grid application seems a promising method for researching the moral significance of teaching from a ‘life world’ perspective. However, we encountered several challenges employing the repertory grid in its standard form for an inquiry into the inherent moral significance of teachers’ everyday classroom interactions. In this article we will set out in detail how, on the basis of the standard repertory grid application, we developed a repertory interview method that can be used to collect data that could foster a thorough understanding of the inherent moral significance of teachers’ day-to-day classroom interactions. 相似文献

The purpose of this study was to investigate whether using different focus affects electromyographic (EMG) amplitude and contraction duration during bench press performed at explosive and controlled speeds. Eighteen young male individuals were familiarized with the procedure and performed the one-maximum repetition (1RM) test in the first session. In the second session, participants performed the bench press exercise at 50% of the 1RM with 3 different attentional focuses (regular focus on moving the load vs contracting the pectoralis vs contracting the triceps) at 2 speed conditions (controlled vs maximal speed). During the controlled speed condition, focusing on using either the pectoralis or the triceps muscles increased pectoralis normalized EMG (nEMG) by 6% (95% CI 3–8%; p = 0.0001) and 4% nEMG (95% CI 1–7%; p = 0.0096), respectively, compared with the regular focus condition. Triceps activity was increased by 4% nEMG (95% CI 0–7%; p = 0.0308) at the controlled speed condition during the triceps focus. During the explosive speed condition, the use of different focuses had no effect. The different attentional focus resulted in comparable contraction duration for the measured muscles when the exercise was performed explosively. Using internal focus to increase EMG amplitude seems to function only during conditions of controlled speed. 相似文献
