The relationship between key state policy variables — (1) relative (private–public) tuition prices, (2) state student-aid funding, and (3) public institution density — and the competitive position of private colleges and universities is examined. Elite private schools are found to be nearly impervious to state policy. Large and moderately selective private institutions are adversely affected by public institution density and low public prices. Such prices divert students who would otherwise prefer these private institutions to similar public schools. State student aid funding most affects the enrollment market shares of the small, low-selectivity private colleges enrolling the greatest proportions of minority and modest-income students. The findings suggest state policies in this era of strong demand for higher education and constrained public sector capacity should use price signals (student aid and public institution pricing) to encourage students to consider seriously whether private higher education might serve their needs as well as or better than public institutions.  相似文献

The huge and sudden increase in the demand for qualified teachers which UPE has occasioned is obliging many countries to develop alternatives to conventional initial training, notably distance programmes and the use of headteachers as trainers of their staff. Universal primary, but not secondary, education also implies changing the content of the training curriculum. All these innovations should not be viewed as threatening constraints but as opportunities for progress towards a policy of lifelong professional development. Features of such a policy would include a review of the respective contributions of initial, induction and inservice training, school-based and school-focussed alternatives to the course, a concern with the cost-effectiveness of different strategies, and the active involvement of teachers in their own training.
Zusammenfassung In vielen Ländern hat der weltweite Ausbau des Primarschulwesens einen gewaltigen und plötzlichen Anstieg im Bedarf an qualifizierten Lehrkörpern nach sich gezogen. Dadurch wurden viele Länder gleichermaßen gezwungen, Alternativen zur herkömmlichen Anfangsausbildung zu entwickeln, insbesondere Fernunterricht und Einsatz von Schulleitern bei der Ausbildung ihres Lehrpersonals. Der weltweite Ausbau der Primar-, aber nicht Sekundarerziehung impliziert eine inhaltliche Änderung des Ausbildungscurriculums. All diese Innovationen sollten nicht als bedrohliche Zwänge, sondern als richtungsweisende Möglichkeiten für ein Programm lebenslanger, beruflicher Entwicklung angesehen werden. Eine solche Bildungspolitik würde u.a. einen Rückblich auf anfängliche, einführende und weiterführende Formen der Ausbildung einschließen. Sie würde aber auch die auf Schulen basierten und konzentrierten Alternativen zu dem Kursus gewährleisten. Sie sind die Formen, die Kostenwirksamkeit verschiedener Strategien sichern und die Lehrer aktiv an ihrer eigenen Ausbildung beteiligen.

Résumé La croissance soudaine et intense de la demande d'enseignants qualifiés que l'enseignement primaire universel a provoquée oblige de nombreux pays à recourir à d'autres moyens que la formation initiale conventionelle, notamment à des programmes à distance et à l'emploi des directeurs d'établissement comme formateurs de leur propre personnel enseignant. L'enseignement primaire universel — mais non le secondaire — implique aussi des changements dans le contenu du curriculum de formation. Toutes ces innovations ne devraient pas être regardées comme des contraintes menaçantes mais plutôt comme des occasions de progresser vers une politique de développement professionnel continu. Une telle politique incorporerait les aspects suivants: évaluation des contributions respectives apportées par la formation initiale, la formation à l'entrée en service et celle en cours d'emploi; choix entre le cours traditionnel et celui donné à l'école et centré sur les besoins de l'école; étude du rapport coût-efficacité des différentes stratégies de formation, et participation active des enseignants à leur propre formation.

The present study investigated the utility of 52 items, selected from a readily available item pool developed for instructional purposes, when the items are used to measure critical thinking abilities of biology students. The items yield scores that have reasonable internal consistency reliability. Furthermore, analyses involving ACT, Watson-Glaser Critical Thinking Appraisal, and Group Embedded Figures Test scores also suggest that the critical thinking test items have good concurrent validity. Thus, the measure may be useful in both science instruction and future research regarding critical thinking phenomena.  相似文献

We examine the role of tasks that have the intended effect of teachers re-conceiving the mathematics they teach as comprising a coherent body of meaningful ideas. We ground our discussion in ideas of trigonometry and modular functions and draw from a professional development research project to illustrate our approach. In this project, many teachers experienced dissonance that was rooted in their commitments to their curricular knowledge of trigonometry. Teachers who built new meanings into a coherent whole were those who coordinated them at a micro level. Teachers who saw implications of their own reasoning for student learning were also successful at expressing that reasoning in natural language. We saw a similar pattern in the case of teachers' creation of meanings for action and process conceptions of mod(f(x),g(x)). Teachers who gained insight into implications of their own activities for student learning were the teachers who reasoned at a micro level in regard to the meaning of mod, who coordinated that meaning with a covariational perspective on the behavior of functions, and who expressed that coordination in natural language. We conclude that a primary feature of tasks that promote teachers' construction of coherent mathematical meanings is that they support an overall effort to have teachers engage in the coordination of meanings in the context of explaining significant ideas and relationships.  相似文献

Abstract

This article is both an editorial introduction for this special issue and a distinctive contribution in its own right. The article seeks to extend a dynamic and multiple conception of time to the sociology of education to think beyond the clock time associated with modernity and industrialisation. This need is illustrated through an account and critique of E.P. Thompson’s canonical account of clock time. The article argues that this construction of clock time implicitly frames most work in the sociology of education. The concept of ‘timespace’ offers a way to go beyond both clock time and the current ‘spatial turn’ in the sociology of education that prioritises space over time. It is shown how computerisation also ushers in a new temporality, which works simultaneously with clock time and perhaps presages the move from a disciplinary to control society. The article accepts that there are multiple and dynamic temporalities and correlatively supports a working together of historical and sociological imaginations towards a sociology of education that acknowledges and works with multiple temporalities, empirically, methodologically, theoretically and in research writing.  相似文献

The authors examined whether math fluency was independent from untimed math and from reading using 314 pairs of school-aged twins drawn from the Western Reserve Reading and Math Projects. Twins were assessed through a 90-min home visit at approximately age 10 and were reassessed in their homes approximately 1 year later. Results suggested that the shared environment and genetics influenced the covariance among math fluency, untimed math measures, and reading measures. However, roughly two thirds of the variance in math fluency was independent from untimed math measures and reading, including reading fluency. The majority of this independent variance was the result of genetic factors that were longitudinally stable across two measurement occasions. These results suggest that math fluency, although related to other math measures, may also be a genetically distinct dimension of mathematics performance.  相似文献

ObjectiveStudies have consistently demonstrated a lack of agreement between youth and parent reports regarding youth-witnessed violence. However, little is known about whether disagreement is associated with poorer outcomes and less utilization of mental health services. The purpose of the current study was to examine disagreement among youth and parents about youth witnessed violence, and determine whether concordance predicted trauma symptoms and recognition of need and receipt of counseling services.MethodsConcordance about youth-witnessed violence was examined in 766 dyads from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN). Youth participants self-reported trauma symptoms, caregivers indicated youth need for and receipt of services. Both youth and parents provided information about youth-witnessed violence exposure in the last year.ResultsResults showed youth and caregivers differed significantly about youth-witnessed violence. Specifically, 42% of youth reported youth-witnessed violence, compared to only 15% of parents. For those parents who reported youth-witnessed violence, only 29% reported an identified need for services and only 17% reported the youth had received any mental health services. Concordance between parent–youth dyads was associated with greater identified need for services but was not associated with the use of counseling services or trauma symptoms.ConclusionsYouth who reported witnessing violence reported more frequent trauma symptoms regardless of concordance. Parents from dyads in which both informants reported youth-witnessed violence were more likely to endorse need for, but not receipt of counseling services. Given this association between youth-witnessed violence and mental health problems, more work is needed to identify barriers to concordance as well as service utilization.  相似文献

This paper presents a conceptual analysis for students’ images of graphs and their extension to graphs of two-variable functions. We use the conceptual analysis, based on quantitative and covariational reasoning, to construct a hypothetical learning trajectory (HLT) for how students might generalize their understanding of graphs of one-variable functions to graphs of two-variable functions. To evaluate the viability of this learning trajectory, we use data from two teaching experiments based on tasks intended to support development of the schemes in the HLT. We focus on the schemes that two students developed in these teaching experiments and discuss their relationship to the original HLT. We close by considering the role of covariational reasoning in generalization, consider other ways in which students might come to conceptualize graphs of two-variable functions, and discuss implications for instruction.  相似文献

This study explored the relationship between identity development, as gauged by Marcia's identity development construct, and student perception of instructor political bias. Regression analysis was employed to compare participant responses on the Ego Identity Process Questionnaire, a measure of Marcia's construct, with the Political Bias in the Classroom Survey, a measure gauging perceptions of and reactions to instructor political bias. The EIPQ's commitment scale was found to be a significant positive indicator for the PBCS's perception scale, suggesting that students who are strongly committed to their identity are more likely to perceive an instructor as having a political bias. Recommendations are made for how to address perceptions of political bias.  相似文献
