The final session of the National Research Center on Learning Disabilities (NRCLD) Responsiveness-to-Intervention (RTI) Symposium, "What are alternative models to LD identification other than RTI?" included four papers that discussed concerns over the exclusive reliance on an RTI approach to learning disability identification, considerations for analyzing proposed LD identification models, and various alternatives to LD identification. The work of the participating panelists is summarized in this discussant paper, and next steps for the NRCLD in light of these presentations are suggested.  相似文献

In the spring of 2002 the Ontario College of Teachers began a research project in order to foster awareness of the Standards of Practice for the 187 000 teachers in the province. Case work, in which 18 teachers representative of the College's membership wrote narratives describing their professional dilemmas, was the methodology chosen. Through reflection and collaborative group work these practitioners co‐created a set of cases, mapping them back to the standards in order to ascertain how the standards had been embedded or absent from their daily practice. To validate the effectiveness of this method, we used the cases in pre‐service, in‐service, principal and supervisory personnel venues. We also recorded the impact of the ‘case institute’ in a focus group session with the original writers. Augmented by commentaries from internationally known teacher educators, this text will be sent to all provincial school boards as part of a resource kit to educate teachers about the standards of practice.

Au printemps 2002, l'Ordre des enseignantes et des enseignants de l'Ontario amorçait un projet de recherche ayant pour but de sensibiliser les 187 000 enseignants de la province aux normes d'exercice de leur profession. L'étude de cas rédigés par 18 enseignants membres de l'Ordre est la méthode qui allait servir à présenter divers dilemmes professionnels. Ainsi, ces praticiens ont réfléchi et travaillé ensemble pour présenter des cas et les rattacher aux normes afin de déterminer la présence ou l'absence des normes dans leurs pratiques quotidiennes. Pour valider l'efficacité de cette méthode, nous avons mis les cas à l'épreuve lors d'activités organisées pour les étudiants des facultés d'éducation, des enseignants en perfectionnement professionnel, des directeurs d'école et des agents de supervision. Nous avons également réuni les 18 rédacteurs pour discuter de l'impact des ateliers de rédaction de cas. Le texte, auquel s'ajoutent les commentaires d'éducateurs de renommée internationale, fera partie de la trousse de ressources qui sera envoyée à tous les conseils scolaires de la province pour initier les enseignants aux normes d'exercice de la profession.

Im Frühjahr 2002, unternahm das Ontario College of Teachers einen Forschungsprojekt mit dem Ziel, das Bewußtsein der Normen der Praxis unter den 187,000 Lehrer des Bundeslandes Ontario zu fördern. Die gewählte Methodologie war die Untersuchung von spezifischen Fallberichten, in denen 18 Lehrer, die repräsentativ für die Mitglieder der Organisation dastehen, ihre Entscheidungen im beruflichen Alltag begründeten. In einem von Überlegung, Zusammenarbeit und Gruppenarbeit geprägten Verfahren schufen diese Lehrer und Lehrerinnen einen Korpus der Fälle, die sie anschließend zu den Berufsnormen zurückverfolgten, um festzustellen, wie die Normen sich in der täglichen Praxis eingebettet hatten oder das Gegenteil. Um die Wirksamkeit der Methode zu bestätigen, wurden Einzelfälle in vorberuflichen, beruflichen, Direktor‐ und Aufsichtsstellen‐bezogenen Umgebungen ausgesucht. Die Wirkung der Falluntersuchungen wurde auch in einer Diskussionsrunde mit den Autoren aufgenommen. Dieser Text, bereichert durch Kommentare von Lehrerausbildern von internationalem Ruf, wird an alle Schulverwaltungen im Bundesland Ontario als Bestandteil eines Ressourcen‐Compendiums versandt, mit dem Ziel, Lehrer über die Normen der Berufspraxis weiterzubilden.

En la primavera del 2002, el Colegio de Profesores de Ontario inició un proyecto de investigación para crear conciencia entre los 187,000 maestros en la provincia sobre los estándares de práctica profesional. La metodología elegida fue el ‘Estudio de antecedentes’ en la que un grupo representativo de la membresía del Colegio, conformado por 18 maestros, redactó historias contando sus dilemas profesionales. Tras mucha reflexión y trabajo mancomunado de equipo, estos profesores crearon colectivamente un conjunto de casos, trazando un mapa vinculándolos a los estándares y así poder determinar de qué manera estos estándares habían estado arraigados en su práctica profesional cotidiana o si los habían dejado de lado. Para validar la eficacia de este método, aplicamos los casos en varios contextos docentes: estudiantes de la facultad de educación, capacitación profesional para docentes, directores de plantel y superintendentes de las juntas directivas escolares. También tomamos nota del impacto del ‘Taller para la redacción de casos’ en una sesión de enfoque grupal con los propios autores. Este texto, que ha sido complementado con comentarios de capacitadores de maestros conocidos internacionalmente, será enviado a todas las Juntas Directivas de las escuelas provinciales como parte del kit de recursos para educar a los profesores sobre los estándares de práctica profesional.  相似文献

The relation of parenting style to adolescent school performance   总被引:21,自引:0,他引:21  
This article develops and tests a reformation of Baumrind's typology of authoritarian, permissive, and authoritative parenting styles in the context of adolescent school performance. Using a large and diverse sample of San Francisco Bay Area high school students (N = 7,836), we found that both authoritarian and permissive parenting styles were negatively associated with grades, and authoritative parenting was positively associated with grades. Parenting styles generally showed the expected relation to grades across gender, age, parental education, ethnic, and family structure categories. Authoritarian parenting tended to have a stronger association with grades than did the other 2 parenting styles, except among Hispanic males. The full typology best predicted grades among white students. Pure authoritative families (high on authoritative but not high on the other 2 indices) had the highest mean grades, while inconsistent families that combine authoritarian parenting with other parenting styles had the lowest grades.  相似文献

Graphs are one of the primary means of exploration and communication in the practice of science, but students in science laboratories are customarily taught only the low-level mechanics of constructing a single kind of graph when given a table of information. The use of a microcomputer can relieve the drudgery of plotting, allowing students to pursue higher-level issues in the design and interpretation of graphs through repeated “thought experiments.” We introduced computer-assisted graphical data analysis to inner-city high school students with weak math and science backgrounds, emphasizing the dynamic manipulation of various kinds of graphs to answer specific questions. Drawing on extensive recordings and classroom observations, we describe examples of the performance of these students on open-ended problem-solving tasks in which graphs can be used to arrive at meaningful answers to applied data analysis problems.  相似文献

Historians have observed that the period 1860–1890 was educationally progressive. This paper identifies the renaissance with the creation of the General Synod of the Church of Ireland in the aftermath of Church Disestablishment. Disestablishment legislation facilitated the inclusion of the laity in Synod. The paper argues that the lay-clerical dynamic generated educational reform at all levels of provision. Post-Reformation denominational divisions qualify the discussion. The structure of Synod – General Synod, Diocesan Synods, Boards of Education and Education Committees – was the outcome of an intense debate as the post-Disestablishment Church of Ireland sought to reinvent itself. The ‘art’ of the title refers to Synod’s adroit use of this structure in promoting educational reform that mitigated tensions surrounding the religious-secular conflict which characterised Irish post-Famine modernisation. Synod’s role as agent of educational reform constitutes the theme. The paper aims to contribute to what, regretfully, remains an undeveloped historiography.  相似文献

Multidimensional sealing and related analytic procedures were used to estimate the accuracy of a set of goals used to pattern the design of a graduate curriculum. The analysis suggests that this goal set faithfully represents the essential elements within the area of professional practice to be taught. The procedures described have utility for a wide range of goal-focused analyses.  相似文献

The results of recent studies into the use of the concept mapping heuristic seem to demonstrate that meaningful learning results through its use in science classrooms. While this underscores the need to use more effective instructional strategies in science teaching, the issue of the intervening variable of anxiety in learning and science achievement, and the possible use of a metacognitive strategy in anxiety reduction have not been addressed. This study, therefore, sought to find out if the metacognitive strategy of concept mapping reduces anxiety and thereby enhances achievement in biology. A total of 51 (30 boys, 21 girls) senior secondary one (grade 10) students participated in this experiment. Two instruments—the Zuckerman Affect Adjective Checklist and the Biology Achievement Test—were used in pre- and posttest administrations to measure the treatment effect on anxiety and achievement, respectively. Findings support the stand that concept mapping is significantly more effective than the traditional/expository teaching strategy in enhancing learning in biology. In addition, it apparently reduces students' anxiety towards the learning of biology. A significant reduction of anxiety was noticed for male subjects.  相似文献

Sialic acid, the end moieties of the carbohydrate chains are biologically important and essential for functions of glycoconjugates and are reported to be altered in cancer patients. Two hundred and twenty five breast cancer (BC) patients, 100 patients with benign breast disease (BBD) and 100 healthy females (controls) were enrolled for the study. Eight hundred and twenty four follow-up samples of 225 breast carcinoma patients were also evaluated. The association of sialic acid forms, sialyltransferase and α-2–6 sialoproteins levels with presence and extent as well as prognosis of breast carcinoma was studied. Serum sialic acid forms and sialyltransferase revealed significantly elevated levels among untreated breast cancer patients as compared to the controls, patients with BBD as well as cancer patients in remission. Non-responders showed comparable levels of the markers with those found in breast cancer patients at the time of diagnosis. Higher levels of sialic acid forms at diagnosis were associated with poor prognosis. A positive correlation between serum levels of different forms of sialic acids and extent of malignant disease was observed. The changes in serum proteins with terminal α-2–6 sialic acid correlated well with alterations in the levels of sialic acid forms and sialyltransferase. Malignant tissues showed elevated levels of sialic acid and sialyltransferase as compared to surrounding normal tissues. The results suggested potential utility of these markers in evaluation of clinical outcome.  相似文献

The rate of citation duplication was examined in three databases: MEDLINE, BIOSIS, and LIFE SCIENCES COLLECTION. Duplicate citations were found to be more pertinent than unique citations. The duplicate citations came from a highly compact literature, while those from a single database were very widely scattered. The pertinent duplicated citations were more likely to be retrieved in searches that had more terms overall, had a higher percentage of thesaurus terms, and had terms which appeared in both title and abstract. These results suggest that the rate of duplication of citations in multidatabase searches may be used to rank output according to probable pertinence.  相似文献
