Achievement disparities between American Indian students and non-American Indian peers are persistent and well documented. Student engagement is a promising target for intervention given its relation to academic achievement. This study investigated the relation between specific teacher practices (opportunities to respond [OTRs], praise, and reprimands) and classroom on-task behavior in an urban, public K–8 school that serves primarily American Indian students. OTRs and praise were positively associated with student on-task behavior, whereas reprimands were negatively associated with on-task behavior. Results from multilevel logistic regression indicated that OTRs significantly increased the likelihood that a classroom was highly on-task, whereas the reprimands significantly decreased the likelihood. Praise did not have a significant effect after controlling for the other variables in the model. Results are interpreted in a context of evidence-based instructional practices for increasing OTRs and praise, decreasing reprimands, and ultimately enhancing on-task behavior in an urban classrooms serving primarily American Indian youth. 相似文献

This essay looks at three contemporary Jewish American playwrights: Tony Kushner, Martin Sherman and Deb Margolin, whose plays
ask fundamental questions about Jewish identity in its political, cultural and spiritual dimensions. Breaking from the concerns
of their theatrical predecessors, most of whom ignored or disguised their Jewish roots, these playwrights draw on profoundly
Jewish concepts to reconfigure narratives of redemption, obligation, ethical community, and Messianic utopianism. Their plays
are characterized by a sensibility of “unruly difference.” Attracted by the politics of marginality; these writers re-imagine
otherness in plays that celebrate a different understanding of faith and conjure the sublime. By carving out a more capacious
definition of Judaism that embraces contradiction and contention, faith and doubt, progressive social vision and deepened
spiritual commitment, they sit aslant the mainstream. They are drawn to their understanding of the spiritual power and cultural
grandeur of the Jewish heritage, but question the politics of accommodation and the limitations of tradition and law. The
ambivalence these writers express about Judaism adds to the complexity of their writing and to its value as a cultural indicator.
Working in new idioms, they refute traditional discourses and dominant paradigms of conformity and coalescence that characterize
modern Jewish-American life. 相似文献

Previous studies of letter recognition have not found priming for abstract letter identities. We used a task that required participants to decide whether a target is the same or different from a reference letter presented in opposite case, which avoids the shortcomings of tasks used in previous studies. We found robust priming effects in this task, which were the same size for letter pairs that have similar visual features across case (e.g., c/C, x/X) and dissimilar features (e.g., a/A, b/B). Also, the pattern of priming was the same whether the prime was in the same or different case as the reference. We take these findings as evidence that abstract letter identities support priming in this task. We suggest that the same-different match task is a useful tool for studying representations used to support masked priming in letter recognition and with other stimuli with limited set size. 相似文献

Language evolution as a Darwinian process: computational studies 总被引:1,自引:0,他引:1
This paper presents computational experiments that illustrate how one can precisely conceptualize language evolution as a
Darwinian process. We show that there is potentially a wide diversity of replicating units and replication mechanisms involved
in language evolution. Computational experiments allow us to study systemic properties coming out of populations of linguistic
replicators: linguistic replicators can adapt to specific external environments; they evolve under the pressure of the cognitive
constraints of their hosts, as well as under the functional pressure of communication for which they are used; one can observe
neutral drift; coalitions of replicators may appear, forming higher level groups which can themselves become subject to competition
and selection.

Gestural communications of 10 mild and moderate aphasics and five controls were examined in two conditions: Face-to-face informal dyadic conversation and restricted visual access between speaker and listener. Gestural production was significantly reduced with restriction of visual access, supporting the posited communicative function of the hand and arm gestures investigated in this study. No differences were found between aphasic and control subjects in the rate of gestural communication in the natural condition of face-to-face interaction. Moderate aphasics, however, were found to produce proportionally fewer of the complex semantic modifying and relational communicative gestures and more nonspecific, nonconsensually shared, unclear gestures. Gestural complexity was significantly negatively correlated with measures of linguistic impairment for the aphasics. The relationship between the frequency and complexity of communicative gestures and concurrent verbalizations was also examined. The findings of this study provide confirmation for the view that there is an identifiable class of gestures utilized by aphasics for communication, aphasics are impaired in their gestural communicative competence in natural conditions of communication, and the quality of aphasics' gestural communications parallels changes in their verbal communication patterns. 相似文献
