The role of vision was examined as infants prepared to grasp horizontally and vertically oriented rods. Hand orientation was measured prior to contact to determine if infants differentially oriented their hands relative to the object's orientation. Infants reached for rods under different lighting conditions. Three experiments are reported in which (1) sight of the hand was removed (N = 12), (2) sight of the object was removed near the end of the reach (N = 40, including 10 adults), and (3) sight of the object was removed prior to reach onset (N = 9). Infants differentially oriented their hand to a similar extent regardless of lighting condition and similar to control conditions in which they could see the rod and hand throughout the reach. In preparation for reaching, infants may use the current sight of the object's orientation, or the memory of it, to orient the hand for grasping; sight of the hand had no effect on hand orientation. 相似文献

Infants, preschoolers, and adults were tested to determine the shortest time interval at which they would respond to the precedence effect--an auditory phenomenon produced by presenting the same sound through 2 loudspeakers with the input to 1 loudspeaker delayed relative to the other. The delayed sound is not localized at its source until time delays between onsets are lengthened beyond a critical limit, or threshold. Thresholds for the precedence effect were defined as the delay interval below which listeners respond only to the leading loudspeaker and above which they respond to both loudspeakers. Threshold estimates were determined for adults and preschoolers with an ascending and descending series, followed by a method of constant stimuli series. Infants were trained to respond to the delayed sound using a visually reinforced headturning procedure. For clicks, preschoolers' and adults' thresholds were around 12 msec, while 6-month-olds stopped responding to the delayed sound around 25 msec. A similar developmental difference in threshold was expressed between preschoolers and adults for a more complex sound, with younger subjects hearing the precedence effect over a longer time delay. 相似文献

Anchored in national longitudinal data analyzed through hierarchical linear and non-linear modeling, this study found that
African-American students have a similar probability of obtaining a BA degree whether they attended a historically Black college
or university (HBCU) or a historically White college or university (HWCU). Among African-Americans, females are more likely
to obtain a baccalaureate degree than males. Especially given that HBCUs are significantly underfunded relative to HWCUs,
the findings of this study lend support to the proposition that HBCUs contribute significantly to higher education in this
country and merit strong support from both the public and private sectors.
This paper was presented at the American Education Research Association Conference in April 2005. 相似文献

This study was done to examine the effect of answer changing on multiple-choice test performance among good and poor readers in the eighth grade. Although the gains of poor readers were higher than those of good readers, all subjects profited significantly from changing their answers on items. For all subjects, when a single response was changed, there was a two-to-one chance that the new response would raise rather than lower the final score. Gains from answer changing on test items were slightly higher for poor readers as a group than were those for good readers. However, the result was determined not to be significant. More important, this hypothesis is strengthened by the fact that all subjects profited from answer changing. Therefore, the results were interpreted as lending support to the notion that answer-changing response among young examinees should be encouraged if there is a reasonable doubt about their “first impression.” 相似文献

In response to the rise of collaborative learning within education, two teacher educators redesigned their courses to explore the complexities of pedagogy within a New Learning framework. Multi‐age grouping provided opportunities for pre‐service teachers to work with others from different year levels on an interdisciplinary assessment task. As a result of this approach to teaching and learning, pre‐service teachers were challenged and resistance arose. These acts of student resistance provided opportunities for examining the dynamics and complexity of collaborative learning and the implications this has for teachers in new times. In particular, it explores the tension around intervening and ignoring students' resistances created by engaging in new learning pedagogy. 相似文献

Although professional learning communities are often promoted as unique learning opportunities, little is known about how they get started and how they are sustained. For this reason, group members are often unprepared, and then frustrated, by inevitable group tensions. With this in mind, Karl Weick's [(1979). The social psychology of organizing. Reading, MA: Addison-Wesley] model of means convergence was used to analyze the social dynamics of a small group of Middle Years teachers over a 2-year period as they implemented Egan's [(1992). Imagination in teaching and learning: The middle school years. Chicago, IL: The University of Chicago Press; (1997). The educated mind: How cognitive tools shape our understanding. Chicago, IL: The University of Chicago Press] theory of Imagination and Learning to their practice. Along with the analysis of journal entries, focus-group discussions, and individual interviews, Weick's (1979) four developmental stages of collaboration provide a broader understanding of why conflict occurs in learning communities and its effect on collaborative learning. 相似文献
