Die trotz rechtlicher Gleichstellung bestehenden faktischen Ungleichgewichte zwischen den Geschlechtern in Bezug auf die Verteilung von Arbeitspl?tzen bzw Leitungsfunktionen führten im Bereich des ?ffentlichen Dienstes zur Einführung von Geschlechterquoten. Für die Universit?ten sehen das Universit?tsgesetz (UG) bzw das Bundes-Gleichbehandlungsgesetz (B-GlBG) die bevorzugte Aufnahme von Frauen einerseits in bestimmten Universit?tsgremien, andererseits bei der Besetzung von Stellen und bei Bef?rderungen innerhalb der universit?ren Strukturen vor. Der folgende Beitrag versucht die verfassungsrechtlichen Fragestellungen (Vereinbarkeit mit Gleichheitssatz, Bestimmtheitsgrundsatz) im Zusammenhang mit den Quotenregelungen des UG bzw des B-GlBG in concreto aufzuarbeiten bzw allgemein zur Frage der Gerechtigkeit und der rechtspolitischen Notwendigkeit von Quotenregelungen Stellung zu nehmen.  相似文献

Construct3D is a three dimensional geometric construction tool based on the collaborative augmented reality system Studierstube. Our setup uses a stereoscopic head mounted display (HMD) and the Personal Interaction Panel (PIP) - a two-handed 3D interaction tool that simplifies 3D model interaction. Means of application in mathematics and geometry education at high school as well as university level are being discussed. A pilot study summarizes the strengths and possible extensions of our system. Anecdotal evidence supports our claim that the use of Construct3D is easy to learn and encourages experimentation with geometric constructions.  相似文献

The issue of literacy retention is central to the educational policy concerning of most developing countries. It has been variously suggested that 4–6 years of primary education may serve as an inoculation against ‘relapse’ into illiteracy in the Third World. This paper reports on one of the first longitudinal studies designed to address this question, by investigating the nature of literacy and cognitive retention in a sample of 72 adolescents two years following fifth grade departure from primary school in Morocco. The present study found that these school leavers, when reassessed two years later, showed a significant increase in performance in first literacy (Arabic), modest gains in second literacy (French), no change in cognitive skills, and a decrement in math skill. Furthermore, urban leavers gained more literacy than rural leavers, and girls more than boys. The present findings do not support the hypothesis of literacy ‘relapse’ or loss of academic/cognitive skills after five grades of primary schooling. It was also found that girls retained more academic skills than boys, but were much less likely to be employed, a finding which calls into question certain claims about the impact of schooled knowledge and literacy on employment in developing countries.  相似文献

Abstract

Mathematicians use example generation to test and verify mathematical ideas; however, the processes through which undergraduates learn to productively generate examples are not well understood. We engaged calculus students in a teaching experiment designed to develop skills in productively generating examples to learn novel concepts. This article presents three student case studies. These case studies are representative of our findings and serve to summarize the activities we found useful. They also serve as examples of various student experiences during the teaching experiment. One student expressed a continued negative view to using example generation. Two increased in skills and experience and expressed positive changes in views.  相似文献

Two experiments with rabbits investigated the concordance of two measures of conditioning, eyeblink and potentiated startle, during a blocking sequence with paraorbital shock reinforcement. In both, a shift in the locus of shock from one eye to the other between the conditioning of an element and a compound of that element and a new cue had differential effects on the two measures of conditioning to the new cue. When the shock was unchanged, diminished conditioning in relation to controls (i.e., blocking) was observed on both measures. When the shock was changed, little conditioning was observed in startle, but control-equivalent amounts were observed in eyeblink (i.e., blocking occurred on the former but not the latter). The results are interpreted as showing a dissociation of the associative learning involving the emotive features of Pavlovian reinforcers and that involving the remaining sensory-perceptual features, and more compatible with a diminished US-processing, than with a CSprocessing, view of blocking.  相似文献

Nearly 1,000 management students enrolled in New Zealand's Technical Correspondence Institute during 1980‐1982 were mailed a questionnaire and followup letters from March ‐‐ July, 1983. Response rate was 76.9% (N=724). Did dropouts (3.43%) differ from persisters in their preferences for supplementary or alternative educational technologies? Dropouts were more receptive to telephone and audio taped communications and seminars. Audio tape and seminar variables were among surviving predictors of dropout after extensive multiple linear regression analyses. Distance education institutions should consider using multiple communication channels in order to cater to diverse student learning styles.  相似文献
