ResumenEn este estudio se realiza una revisión de los sistemas de evaluación de la escritura y de estudios relacionados. Se comienza con una visión de conjunto de las dificultades principales en el estudio de la evaluación de la escritura, y de la importancia y utilidad que tiene un sistema de evaluación de la escritura en distintas áreas de conocimiento. Posteriormente se analiza cuál es el objeto de evaluación de los diferentes sistemas y qué medidas se utilizan en las investigaciones acerca de la escritura. A este respecto se expone un modelo del producto de la escritura que permite organizar, de modo prácticamente exhaustivo, las medidas del producto escrito. Tras resumir los requisitos, que según distintos autores debería cumplir cualquier sistema de evaluación de la escritura, se clasifican los sistemas de evaluación en base a si el objeto de análisis es el proceso o el producto de la escritura, definiendo sus características generales. A su vez, se exponen diferentes clasificaciones de los sistemas de evaluación del producto escrito, realizadas principalmente en función de la estrategia de evaluación. Esta revisión muestra la falta de acuerdo existente entre los diferentes autores respecto al objeto y el modo de evalución, así como a la terminología utilizada. 相似文献

To examine whether the intervention effects of Familias Unidas, compared to community practice, on Hispanic adolescent alcohol and drug use varies by nativity status (i.e., U.S.-born and foreign-born). A total of 213 eighth grade Hispanic adolescents with behavior problems and their primary caregivers were assigned randomly to one of two conditions: Familias Unidas or Community Control. Participants were assessed at baseline and at 6, 18, and 30 months post baseline. Results showed that, the effects of Familias Unidas on alcohol use was moderated by nativity status. Specifically, Familias Unidas was efficacious in preventing/reducing alcohol use for U.S.-born youth, but not foreign-born. No moderating effects were found for drug use. These findings suggest that prevention interventions may be more efficacious in preventing/reducing alcohol use among certain Hispanic adolescent subgroups.

This paper discusses Husserl’s views on physical theories in the first volume of his Logical Investigations, and compares them with those of his contemporaries Pierre Duhem and Henri Poincaré. Poincaré’s views serve as a bridge to
a discussion of Husserl’s almost unknown views on physical geometry from about 1890 on, which in comparison even with Poincaré’s—not
to say Frege’s—or almost any other philosopher of his time, represented a rupture with the philosophical tradition and were
much more in tune with the physical geometry underlying the Einstein-Hilbert general theory of relativity developed more than
two decades later. 相似文献

In previous investigations (Jacobson, Berger, Bergman, Millham and Greeson, 1971; Jacobson and Greeson, 1972), it was reported that as a result of the use of a behavior modification program, preschool children from poverty backgrounds demonstrated rapid conceptual acquisition. In addition, the Ss increased from the dull-normal to the normal range of intellectual functioning within approximately 20 hr of program participation. Since the increases in IQ found were most pronounced for children of lowest IQ (IQs = 46–83), the investigators hypothesized that the program would prove to be useful with Ss of greater cognitive and behavioral deficits than the initial population investigated.The present study reports the use of a variant of the conceptual acquisition program with an institutionalized, profoundly retarded microcephalic teenager with chronic brain syndrome and cerebral palsy. Prior to the study the boy demonstrated neither language nor an ability to comprehend and follow verbal directions. 相似文献

Team performance and coordination have gained considerable interest in disparate fields (e.g., aviation, process control, medicine, and wartime operations). Team-Track, a C program that allows controlled experimental manipulation of team conditions, was developed to meet the research needs resulting from this interest. Using Team-Track, one can manipulate task interdependence, team staffing, relative contributions of team members, communications, and informational displays in a low-cost environment. The dependent measure of performance generated by the program is the absolute tracking error along each dimension. The program is ideal for investigating team interactions as it allows for orthogonal manipulation of team variables, therefore accommodating a multitude of research paradigms. 相似文献

It has been suggested that certain theoretically important anomalous results in the area of verbal short-term memory could be attributable to differences in strategy. However there are relatively few studies that investigate strategy directly. We describe four experiments, each involving the immediate serial recall of word sequences under baseline control conditions, or preceded by instruction to use a phonological or semantic strategy. Two experiments varied phonological similarity at a presentation rate of one item every 1 or 2 seconds. Both the control and the phonologically instructed group showed clear effects of similarity at both presentation rates, whereas these were largely absent under semantic encoding conditions. Two further experiments manipulated word length at the same two rates. The phonologically instructed groups showed clear effects at both rates, the control group showed a clear effect at the rapid rate which diminished with the slower presentation, while the semantically instructed group showed a relatively weak effect at the rate of one item per second, and a significant reverse effect with slower presentation. The latter finding is interpreted in terms of fortuitous differences in inter-item rated associability between the two otherwise matched word pools, reinforcing our conclusion that the semantically instructed group were indeed encoding semantically. Implications for controlling strategy by instruction are discussed. 相似文献

Whereas biomedical products are required to be tested for safety with respect to vulnerable organ systems, psychosocial treatments are not required to be tested for safety with respect to vulnerable social systems such as the family. This article provides some evidence for the need to document the potential negative effects of psychosocial treatments on family-level outcomes. Three randomized controlled trials are reviewed in which independent ratings or self-reports of family functioning were measured. Each of the 3 studies compared the efficacy of a family and a nonfamily treatment. Totally unexpectedly, the nonfamily treatment in each of the 3 trials demonstrated significant declines in family functioning. The authors suggest that psychosocial treatments with vulnerable populations have the potential to produce negative side effects on families. Therefore, it is important to conduct further research to determine whether safety studies should be required for psychosocial treatments. 相似文献

This work compares the sensitivity of five modern analytical techniques for detecting the effects of a design with measures which are partially repeated when the assumptions of the traditional ANOVA approach are not met, namely: the approach of the mixed model adjusted by means of the SAS Proc Mixed module, the Bootstrap-F approach, the Brown-Forsythe multivariate approach, the Welch-James multivariate approach and Welch-James multivariate approach with robust estimators. Previously, Livacic-Rojas, Vallejo and Fernández found out that these methods are comparable in terms of their Type I error rates. The results obtained suggest that the mixed model approach, as well as the Brown-Forsythe and Welch-James approaches, satisfactorily controlled the Type II error rates corresponding to the main effects of the measurement occasions under most of the conditions assessed. 相似文献
