This article makes the argument that the present discourse on developmental appropriateness needs to be expanded. Four points are made: First, the present discourse assumes a consensus about child development that is more apparent than real; second, it is premised on a suspect notion of broad, universal stages; third, it ignores an important alternative perspective to the dominant individualist perspective on learning and development; and fourth, it ignores an important alternative perspective to the dominant view of the relationship between learning and development. Critiques are made and alternative perspectives presented.  相似文献

This co-authored article outlines the research process and key findings from the Stratus Writers Project, a participatory action research project with a group of seven students on the autistic spectrum at a university in the North of England. The project explores their experiences of university through critical autobiographies and offers unique insider perspectives into some of the key issues, challenges and successes. Building on a participatory action research approach, the data were collected by the participants themselves; however, this study departs from traditional research in that the participants also analysed the data, thus offering rich and potentially overlooked theoretical knowledge. The article concludes by demonstrating the strength of participatory action research approaches by identifying the impact that our project and its findings have had so far.  相似文献

After receiving events in a fixed order, A-B-C…, rats, like people, on being provided with A, may anticipate not only B, a current anticipation, but also C, a remote anticipation. In two experiments, we attempted to determine whether rats’ remote anticipations are mediated by item cues (C elicited by A) or by position cues (C directly elicited by Position 3 cues, which generalize to Position 2). In Experiment 1, rats in a runway received two series of three trials, XNY and ZNN, each in irregular order each day. N signified nonreinforcement; X, Y, and Z signified three qualitatively different food reinforcements. The rats manifested a remote anticipation by running faster on Trial 2 in the XNY series than in the ZNN series. Since the series were presented irregularly, Trial 2 performance cannot be explained on a positional basis alone. It can be explained on an item basis, by assuming that the memory of the Trial 1 reinforcer became associated not only with the Trial 2 event, but with the Trial 3 event as well. Thus on Trial 2 the memory of X signaled N and Y, whereas the memory of Z signaled N and N. Experiment 2 produced the same results, regardless of whether the XNY and ZNN series were presented in regular or irregular order. These results indicate that remote anticipations can be mediated by item associations. They offer no evidence that position associations can do the same, but they do not rule out that possibility.  相似文献

Is Visually Guided Reaching in Early Infancy a Myth?   总被引:4,自引:0,他引:4  
The issue examined was whether infants require sight of their hand when first beginning to reach for, contact, and grasp objects. 7 infants were repeatedly tested between 6 and 25 weeks of age. Each session consisted of 8 trials of objects presented in the light and 8 trials of glowing or sounding objects in complete darkness. Infants first contacted the object in both conditions at comparable ages (mean age for light, 12.3 weeks, and for dark, 11.9 weeks). Infants first grasped the object in the light at 16.0 weeks and in the dark at 14.7 weeks, a nonsignificant difference. Once contact was observed, infants continued to touch and grasp the objects in both light and dark throughout all sessions. Because infants could not see their hand or arm in the dark, their early success in contacting the glowing and sounding objects indicates that proprioceptive cues, not sight of the limb, guided their early reaching. Reaching in the light developed in parallel with reaching in the dark, suggesting that visual guidance of the hand is not necessary to achieve object contact either at the onset of successful reaching or in the succeeding weeks.  相似文献

This study was an exploration of school consultation interactions between instructional consultants and consultees. Of specific interest was how consultants (n = 18) and consultees (n = 18) used verb tense and emotion words during the problem identification and analysis instructional consultation stage, similarities and differences in communication patterns, and whether verb tense and emotion words were related to perceptions of collaboration, consultee outcomes, or client outcomes. Data provided mixed support for study hypotheses. Among the findings, consultants’ past tense verb use negatively correlated with the consultation relationship (r = ?.62, p = .01), consultees’ present tense use correlated with better consultee outcomes (r = .49, p = .05), and positive emotion word use by consultees was correlated with better consultee outcomes (r = .54, p = .05). Implications of these and other findings are explored in the context of interpersonal communication during school consultation.  相似文献

This paper analyses the relationships among life goals, job prospects and fields of study for a sample of young European higher education graduates. The results show that there is a characteristic pattern for each field of study with regard to the variables used. Graduates in a given field have similar life goals and job prospects, as well as a similar educational and social background, irrespective of cultural and labour market differences associated with their country of residence.  相似文献

K-12 Calculator Usage and College Grades   总被引:1,自引:1,他引:1  
We find that students in the big mathematics service courses at the Johns Hopkins University who were encouraged to use calculators in K-12 have somewhat lower grades than those who weren't. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

Some IRT models can be equivalently modeled in alternative frameworks such as logistic regression. Logistic regression can also model time-to-event data, which concerns the probability of an event occurring over time. Using the relation between time-to-event models and logistic regression and the relation between logistic regression and IRT, this article outlines how the nonparametric Kaplan-Meier estimator for time-to-event data can be applied to IRT data. Established Kaplan-Meier computational formulas are shown to aid in better approximating “parametric-type” item difficulty compared to methods from existing nonparametric methods, particularly for the less-well-defined scenario wherein the response function is monotonic but invariant item ordering is unreasonable. Limitations and the potential for Kaplan-Meier within differential item functioning are also discussed.  相似文献
