La revisión que se hace aquí de toda una serie de limitaciones y de errores habituales en la evaluación educativa ayudará sin duda a los lectores a tomar conciencia del problema y, como propone el autor, a concebir la evaluación más como un método para posibilitar oportunidades que como vía para establecer categorías. 相似文献

David Banes, Headteacher, and Richard Walter, IT co-ordinator, describe ways in which the Internet has been used by a group of pupils with complex needs at Meldreth Manor school. The rationale, some teaching techniques and methods of evaluating the experiment are discussed, and a range of issues requiring further investigation are identified. 相似文献

In this article, Walter Parker brings structure and agency to the foreground of the current tumult of public schooling in the United States. He focuses on three structures that are serving as rules and resources for creative agency. These are a discourse of derision about failing schools, a broad mobilization of multiculturalism, and an enduring nationalism. Drawing on Anthony Giddens's structuration theory, Parker examines how these discourses figure in redefining school reform, redefining school curricula, and requiring schools once again to serve nationalistic purposes. 相似文献

The Monty Hall dilemma is a probability puzzle in which a player tries to guess which of three doors conceals a desirable prize. After an initial selection, one of the nonchosen doors is opened, revealing that it is not a winner, and the player is given the choice of staying with the initial selection or switching to the other remaining door. Pigeons and humans were tested on two variants of the Monty Hall dilemma, in which one of the three doors had either a higher or a lower chance of containing the prize than did the other two options. The optimal strategy in both cases was to initially choose the lowest-probability door available and then switch away from it. Whereas pigeons learned to approximate the optimal strategy, humans failed to do so on both accounts: They did not show a preference for low-probability options, and they did not consistently switch. An analysis of performance over the course of training indicated that pigeons learned to perform a sequence of responses on each trial, and that sequence was one that yielded the highest possible rate of reinforcement. Humans, in contrast, continued to vary their responses throughout the experiment, possibly in search of a more complex strategy that would exceed the maximum possible win rate. 相似文献
