This paper deseribes our experiences in trying to extend a language tutoring system, LINGER, to deal with Spanish. LINGER is based on Definite Clause Grammar (DCG) notation. It was first developed to teach French (Barchan, Woodmansee and Yazdani, 1986). Unlike traditional language-teaching systems, it incorporates human-like knowledge of the domain it is teaching. Experiences in modifying such systems are relevant both to language teaching and to attempts at turning tutoring systems designed for specific tasks into tools capable of greater generality and use. 相似文献

Over the past decade educational reform has been taking place in the USA and in England and Wales. This paper traces the political pressures to change the social subjects curriculum on both sides of the Atlantic. In England and Wales the new National Curriculum aims to raise educational standards and to increase accountability through a national assessment system. In the USA the Federal Government has set to work on establishing national goals. There is evidence in both countries that the new curricula are emerging from a political process which imposes content and structures upon teachers with little consultation. The paper concentrates on how the social studies curriculum has been affected in this process. It explores the politics of curricular reform by comparing events in the USA and England and Wales and outlines the ways, particularly in the British context, in which the teaching profession has explored the limits of its power and has fought back against central control to make its voice heard.
Zusammenfassung In den letzten zehn Jahren gab es eine Bildungsreform in den USA, sowie in England und Wales. Dieser Bericht studiert den politischen Druck, der zu einer Änderung des Curriculums in den Sozialfächern auf beiden Seiten des Atlantiks geführt hat. In England und Wales soll das neue nationale Curriculum den Bildungsstandard anheben und die Verantwortlichkeit durch ein nationales Bewertungssystem steigern. In den USA begann die Bundesregierung mit der Festsetzung nationaler Ziele, die den Lehrern Inhalte und Strukturen mit wenig Mitbestimmungsrecht auferlegt. Der Artikel konzentriert sich auf die Auswirkungen dieses Prozesses auf das Curriculum der Sozialstudien. Er untersucht die Politik der Curriculums-Reform, in dem Ereignisse in den USA, England und Wales verglichen werden. Insbesondere im britischen Kontext werden Wege aufgezeigt, auf denen der Lehrberuf die Grenzen seiner Macht erforscht und sich gegen eine zentrale Kontrolle gewehrt hat, um Aufmerksamkeit auf sich zu ziehen.
Resumen Durante la última década se ha realizado una reforma de la educación en los EEUU, Inglaterra y Gales. Este trabajo esboza las presiones políticas de cambiar los planes de estudio de los sujetos sociales a ambos lados de Atlántico. En Inglaterra y Gales, elNew National Curriculum aspira a crear estándares de la educación y a incrementar la responsabilidad a través de un sistema nacional de valoración. En los EEUU, el Gobierno Federal ha comenzado a trabajar en la fijación de objetivos nacionales. Es evidente que en ambos países los nuevos planes de estudios están emergiendo de un proceso político que impone contenidos y estructuras a los maestros, consultándolos poco o nada. El trabajo se concentra en el impacto que ha sufrido el curriculo de estudios sociales en este proceso. Explora la política de la reforma curricular comparando acontecimientos de los EE UU y de Inglaterra y Gales y proporciona una idea general de los modos, particularmente en el contexto británico, en los que la profesión de enseñanza ha explorado los límites du su poder y se ha defendido contra el control central para hacerse escuchar.
Résumé Au cours de la dernière décennie, une réforme éducative a été engagée aux Etats-Unis, en Angleterre et au pays de Galles. Cet article retrace les pressions politigues qui ont été exercées pour remanier les thèmes sociaux dans les programmes des deux côtés de l'Atlantique. En Angleterre et au pays de Galles, le nouveau curriculum national a pour but d'élever les niveaux de l'enseignement et d'augmenter la responsabilité par un système national d'évaluation. Aux Etats-Unis, le gouvernement fédéral a entrepris d'établir des objectifs nationaux. Il est évident que dans les deux pays, les nouveaux programmes sont nés d'un processus politique qui a imposé aux enseignants des contenus et des structures en les consultant à peine. L'article se concentre sur les retombées de ce processus sur les programmes d'études sociales. Il étudie la politique de la réforme curriculaire en comparant les événements intervenus aux Etats-Unis et en Angleterre-pays de Galles et souligne, en particulier dans le contexte britannique, la façon dont le corps enseignant a épuisé les limites de son pouvoir et a résisté au contrôle central pour se faire entendre.

Perianal findings in prepubertal children selected for nonabuse: a descriptive study 总被引:6,自引:0,他引:6
The results of the perianal portion of a project designed to collect normative data of the anogenital anatomy from a representative sample of prepubertal children is presented. A total of 318 children were examined by three physicians from a child sexual abuse evaluation program. After screening for the onset of puberty and the possibility of undetected abuse, 267 subjects remained. The sample included 161 girls and 106 boys ranging in age from 2 months to 11 years. The perianal findings that were encountered with the greatest frequency included erythema (41%), increased pigmentation (30%), and venous engorgement (52%) after two minutes in the knee-chest position. Wedge-shaped smooth areas in the midline, with or without depressions, were found both anterior and posterior to the anus in 26% of the children. Anal skin tags/folds were discovered anterior to the anus in 11%. In 49% of the children there was some dilatation of the anus which opened and closed intermittently in 62%. Flattening of the anal verge and rugae occurred during dilatation by the midpoint of the examination in 44% and 34%, respectively. Perianal findings that were found infrequently in all subgroups included skin tags/folds (0%) and scars (1%) outside the midline, anal dilatation greater than 20 mm without the presence of stool in the rectal ampulla (1.2%), irregularity of the anal orifice after complete dilatation (3%), and prominence of the anal verge (3%). No abrasions, hematomas, fissures, or hemorrhoids were encountered. Less commonly detected findings within specific subgroups included perianal erythema in girls (32%) as compared to boys (57%), pigmentation in the lighter skinned white children (22%) when compared to black (53%) and Hispanic (58%) children, and venous congestion at the beginning of the examination (7%) when compared to the same findings after four minutes in the knee-chest position (73%). There were no perianal skin tags/folds found in the boys. The relatively high incidence of perianal soft tissue changes that were found in this study, when compared to the frequency of similar observations in children suspected of having been sexually abused, reemphasizes the caution medical examiners must exercise in rendering an opinion as to the significance of medical findings. 相似文献

While a vast literature exists on students and their learning, work on lecturers and their teaching continues to lag some
way behind. This paper explores the notion that the complexity of Higher Education (HE) today significantly impacts upon what
goes on in the classroom through a two-tiered study. Semi-structured interviews were conducted to explore lecturers’ perceptions
and experiences of teaching a specific module. Interviewees raised issues pertaining to the wider departmental, institutional
and socio-political context. Consequently, focus groups were run with key people in the University to explore their perceptions
of teaching and learning within the current HE climate. The findings suggest that lecturers perceive numerous external factors
to impinge upon their teaching and attempt to militate against these in various ways in order to achieve ongoing enhancement
of learning for students.

The purpose of this study was to determine if achievement on a series of problems was affected by differences among task values within a dimension. Values within inference pattern, goal object, and percept dimensions were studied. One hundred and sixty primary school children participated in the study. An analysis of the results of their achievement on the tasks indicate that task solution is affected by the dimension values used in this study. The results of the study suggest that a multidimensional scale of task dimension values should be constructed in order to assist the curriculum specialist in the construction and sequencing of concept tasks for specific grade levels. 相似文献

Building a metacognitive model of reflection 总被引:2,自引:0,他引:2
An increased value is being placed on quality teaching in higher education. An important step in developing approaches to better instruction is understanding how those who are successful go about improving their teaching. Thus, several years ago we undertook a program of research in which the concept of reflection provided the frame of reference. We envisaged reflection as a process of formative evaluation, and also saw links between reflection and metacognition. What we have documented and analyzed in detail are the reflective processes of six university professors in their day-to-day planning, instructing and evaluating of learners. The result is a metacognitive model and coding scheme that operationalize the process of reflection. Both provide a language for describing reflection and therefore a way to think about how to improve teaching. In this paper, we describe the research and the model and the contributions they make to our understanding of teacher thinking in higher education. 相似文献
