Integration Von Allgemeiner Und Beruflicher Bildung In Westlichen Industrienationen

Zusammenfassung Bisher besteht in vielen Ländern eine Ungleichheit in den beruflichen Abschlüssen des beruflichen Schulwesens und des Allgemeinbildenden Schulwesens. Inzwischen kann man in einigen Industrieländern Entwicklungen beobachten, allgemeine und berufliche Bildung zu verbinden. Es erscheint günstig, am Anfang der Ausbildung eine breite berufliche Grundlagenausbildung in Verbindung mit Allgemeinbildung zu vermitteln, und erst danach eine Spezialisierung vorzunehmen. In diesem Zusammenhang werden Beispiele aus Schweden, den USA (Career Education), der Bundesrepublik Deutschland, Dänemark und der Republik Irland dargestellt.

Up to now in many countries there exists no equality between vocational education and general education in the educational system. In the meantime in some industrial countries a development can be observed to integrate vocational and general education in schools. It seems favourable to offer a broad vocational education in connection with general education at the beginning, and to specialize afterwards. In order to demonstrate this development examples are presented from Sweden, the USA (Career Education), the Federal Republic of Germany, Denmark and the Republic of Ireland.

Résumé Dans de nombreux pays l'égalité entre enseignement professionnel et enseignement général n'est pas encore un fait accompli. Par ailleurs, dans certains pays industrialisés, on a pu observer une tendance à intégrer dans les écoles ces deux types d'enseignement. Il paraît avantageux, au début, de dispenser un enseignement professionnel sommaire en rapport avec l'enseignement général, et de passer à la spécialisation plus tard. L'auteur appuie son exposé d'exemples empruntés à la Suède, aux USA (Career Education), à la République Fédérale d'Allemagne, au Danemark et à la République d'Irlande.

     

The filament forming reactions of vimentin tetramers studied in a serial-inlet microflow device by small angle x-ray scattering

The structural organization of metazoan cells and their shape are established through the coordinated interaction of a composite network consisting of three individual filament systems, collectively termed the cytoskeleton. Specifically, microtubules and actin filaments, which assemble from monomeric globular proteins, provide polar structures that serve motor proteins as tracks. In contrast, intermediate filaments (IFs) assemble from highly charged, extended coiled coils in a hierarchical assembly mechanism of lateral and longitudinal interaction steps into non-polar structures. IF proteins are expressed in a distinctly tissue-specific way and thereby serve to generate the precise plasticity of the respective cells and tissues. Accordingly, in the cell, numerous parameters such as pH and salt concentration are adjusted such that the generation of functional networks is ensured. Here, we transfer the problem for the mesenchymal IF protein vimentin to an in vitro setting and combine small angle x-ray scattering with microfluidics and finite element method simulations. Our approach is adapted to resolve the early assembly steps, which take place in the sub-second to second range. In particular, we reveal the influence of ion species and concentrations on the assembly. By tuning the flow rates and thus concentration profiles, we find a minimal critical salt concentration for the initiation of the assembly. Furthermore, our analysis of the surface sensitive Porod regime in the x-ray data reveals that the formation of first assembly intermediates, so-called unit length filaments, is not a one-step reaction but consists of distinct consecutive lateral association steps followed by radial compaction as well as smoothening of the surface of the full-width filament.     

Observing justice in the primary school classroom

Justice-related situations are a part of students? everyday life. In order to test the antecedents, correlates, and consequences of (in)justice in school, valid measures of justice are needed. To our knowledge, this is the first study to develop an observer low inference rating instrument that can be applied to measure justice in the primary classroom. In two pre-studies, justice-relevant situations in the classroom were extracted and observable indicators for these situations were developed. In the main study, this instrument was used to observe 208 primary school students with regard to their experiences of justice or injustice. In addition to this, other measures of justice were developed to examine the convergence between observer low inference ratings of classroom justice and high inference rating instruments for teachers, students, and external observers.Factor analyses and correlations between the different indices of the observer low inference rating and the high inference rating items suggested that incidents of justice and injustice in the classroom do not tend to co-occur frequently. Teachers do not appear to have a general tendency to treat a child more or less justly across a large number of situations.The findings suggest that a comprehensive assessment of classroom justice requires a multi-method approach where the justice ratings of students, teachers and external observers are all taken into consideration.     

THE DETERMINATION AND EVALUATION OF RESULTS IN THE STUDY PROCESS

Student assessment and grading schemes in higher education institutions should be adapted and applied in such a way that they stimulate students to achieve to the utmost of their abilities. It is not sufficient to simply give a grade to a student for a task accomplished or even to give him an average grade for a series of tasks accomplished during a given time period, a semester, for instance. Rather it is necessary to create an action framework of a kind which links the performance dynamic of both students and teachers so as to ensure the accurate determination, evaluation, and analysis of the joint student‐teacher performance behaviour in such a way that the individual procedures subject to evaluation can be grouped into joint procedures which stimulate self‐determination self‐evaluation, and self‐analysis on the part of students, teachers, and eventually, the employers of graduates. The authors have designed two models which illustrate optimum evaluation procedures of the kind which they favour.     

Rechtliche Rahmenbedingungen für die Gestaltung universit?rer Curricula

Die bereits im Zuge der Autonomie-St?rkung der Universit?ten durch das UOG 1993 im Rahmen der Erlassung des UniStG 1997 vorgenommene Aufwertung der Selbstregelungskompetenzen der Universit?ten bei der Gestaltung des Studienrechts, findet in der Fassung der studienrechtlichen Vorgaben des UnivG 2002 seine konsequente Fortsetzung. Diese Ausweitung der Selbstregelungskompetenzen geht im rechtsstaatlichen Sinne typischerweise (als Gegengewicht) mit besonderen Anforderungen an Rechtsschutz und Rechtssicherheit einher. Insofern hat der universit?re Verordnungsgeber auch auf die in den Gesetzesgrundlagen zum Ausdruck kommenden Wertungen und Grunds?tze eingehend Bedacht zu nehmen.     

Probleme von Lehrerinnen und Lehrern mit der Beurteilung von Schülerleistungen

Zusammenfassung Die Erzeugung, Begründung und Durchsetzung von Leistungsbeurteilungen in der Schule stellt für Lehrkr?fte in verschiedenen Hinsichten ein Problem dar. Einerseits sind die Grenzen des Konzepts der Schulleistung strittig, andererseits gilt es, ungeachtet der defizit?ren wissenschaftlichen Rationalisierung der Praxis der schulischen Leistungsbeurteilung vertretbare Selektionsentscheidungen zu produzieren sowie zwischen den vielfach als widersprüchlich empfundenen Zielsetzungen der F?rderung und der Selektion abzuw?gen. Der Beitrag geht der Frage nach, wie Lehrkr?fte an ?ffentlichen Schulen mit diesen und ?hnlichen Problemen umgehen. Er berichtet über Teilergebnisse eines von der DFG gef?rderten Forschungsprojekts über „Selektionsentscheidungen als Problembereich professionellen Lehrerhandelns“ (Terhart/Langkau/Lüders 1999). Insbesondere werden Befunde einer Dilemma-Studie vorgestellt, in deren Rahmen Lehrkr?fte mit problematischen Zensierungs-und Selektionsentscheidungen konfrontiert und um eine Stellungnahme gebeten worden sind. Dabei stehen keineswegs erneut die vielfach konstatierten Schw?chen des Lehrerurteils im Zentrum der Betrachtung. Ziel des Beitrages ist es vielmehr, die erhobenen Stellungnahmen der Lehrkr?fte als Ausdruck bestimmter Rahmenbedingungen schulischen Bewertungshandelns zu interpretieren, damit einen vertieften Einblick in die Praxis der Leistungsbeurteilung als Praxis einer in Organisationen t?tigen Profession zu geben und Hypothesen für die weitere Forschung zu generieren.

Summary Problems Concerning the Judgement of Pupils’ Performance The generation, justification and assertion of judgements concerning pupils’ performance present teachers with a variety of problems. On the one hand, the boundaries of the concept of pupil performance are controversial whilst, on the other, in spite of the deficiency of scientific rationalization of this practice, adequate selective decisions must be generated and the balance between support and selection must be weighed up. This paper considers the way teachers in public schools cope with these and other similar problems. It reports on some of the results from a DFG-supported research project entitled “Selective decisions as a problem area in professional teaching practice” (Terhart/Langkau/Lüders 1999). In particular, responses from a dilemma study are presented, in which teachers were confronted with problematic selective decisions and asked for their professional opinion. The focal point of this study is not the regularly proclaimed weakness of teachers’ judgements. The objective of this paper is instead to interpret the professional judgement of teachers as an expression of particular conditions of school assessment practice; through this, to offer a deeper insight into the practice of performance assessment conceived of as the practice of a profession which works in organizations, and to generate hypotheses for further research in this field of study.

     

Tier 3 specialized writing instruction for students with dyslexia

Two instructional experiments used randomized, controlled designs to evaluate the effectiveness of writing instruction for students with carefully diagnosed dyslexia, which is both an oral reading and writing disorder, characterized by impaired word decoding, reading, and spelling. In Study 1 (4th to 6th grade sample and 7th to 9th grade sample), students were randomly assigned to orthographic or morphological spelling treatment but all students were taught strategies for planning, writing, and reviewing/revising narrative and expository texts. Both treatments resulted in improvement on three measures of spelling and one measure of composition. Morphological treatment resulted in better improvement in spelling pseudowords, whereas orthographic treatment resulted in better improvement in rate of reading pseudowords. In Study 2 (4th to 6th grade sample), students were randomly assigned to explicit language treatment (phonological working memory + phonological-orthographic spelling + science report writing training) or nonverbal problem solving treatment (virtual reality-based computer simulation, drawing maps, and building clay models). Both treatments used science content material and resulted in significant improvement in spelling and reading pseudowords (accuracy and rate). The surprising finding was that hands-on, engaging science problem solving led to more improvement in phonological working memory than did specialized phonological instruction. Only when spelling instruction emphasized orthography or morphology (Study 1) did real word spelling improve. Preparation of this chapter was supported by Grant Nos. HD25858 and P50 33812 from the National Institute of Child Health and Human Development (NICHD). In Study 1 teaching assistants included Sylvia Abbott, Marci Anderson-Youngstrom, Belle Chennault, Kate Eschen, Noelia Garcia, Sandra Hiramatsu, Lynn Junell, Julia Kim, Stephanie King, Shin-Ju (Cindy) Lin, Rebecca Metzger, Heather Murphy, Jennifer Norton, Sue Palewicz, Rebecca Pirie, and Suzanna West. Also on the assessment team were Sylvia Abbott, Belle Chenault, Kate Eschen, and Rebecca Pirie. Certified teachers Diana Hoffer and Christina Johnson implemented the composition lessons written by the first author. In Study 2, teaching assistants included Nicole Alston-Abel, Leah Altemeier, Wade Altom, Marci Anderson-Youngstrom, Annie Boyd, Nicole Garcia, Laura Gould, Marta Holsinger, Yen-Ling Lee, Shin-Ju (Cindy) Lin, Laurie McCarthy, Heather Murphy, Hema O’Shea, Michelle Proux, Kristine Tardiff, and Kari Terjeson. Janine Jones supervised the assessment team. Margaret McShane and Doug Stock served as administrative assistants.     

Revitalizing Ernst Mach’s Popular Scientific Lectures

Compared to Ernst Mach’s influence on the conceptual development of physics, his efforts to popularize science and his reflections on science literacy are known to a much lesser degree. The approach and the impact of Mach’s popular scientific lectures are discussed in view of today’s problems of understanding science. The key issues of Mach’s popular scientific lectures, reconsidered in the light of contemporary science, still hold a high potential in fascinating a general audience. Moreover, Mach’s grand theme, the relation of the physical to the psychical, is suited to contribute to a dialogue between different knowledge cultures, e.g. science and humanities.
