    The Efficacy of Mathematics Education

    Evidence supports the notion that mathematics education in the United States is inadequate. There is also evidence that mathematics education deficiencies extend internationally. The worldwide mathematics education deficit appears large enough that improving student performance in this educational problem area could yield great economic benefit. To improve the efficacy of mathematics education, education’s root problems must first be understood. Often supposed educational root problems are considered and contrasted against potential deficiencies of mathematics methodologies and curricula that are based on mainstream educational philosophies. The educational philosophies utilized to form early-grade mathematics methodologies and related curricula are judged to be the main reasons for low levels of interest in the subject of mathematics by student populations. An exploration of available literature in regard to how the human brain learns is provided. Two unifications are resultantly hypothesized: interest and learning appear to be mentally intertwined, this unification may serve as the basis for a more effective educational methodology; children are nearly universally interested in the visual arts, arithmetic and geometric mathematical principles are intertwined with the visual arts principles of linear perspective and proportion. An early grade curriculum that relates those mathematical principles via artistic methods (similar to those developed and utilized by master artists and engineers of the Renaissance era) may prove broadly effective at equitably increasing students’ mathematical achievement. Future research in such a direction is highly recommended

    Estimation of the efficiency of two subsystems of the “Energy Towers”

    In order to reduce CO2 emissions, it is necessary to change over to climate-neutral energies as quickly as possible. To achieve this, the use of climate-neutral technologies must be expanded on the one hand, and on the other hand, the efficiency of existing plants, even those that are not climate-neutral, must be increased. In this publication, a new type of plant is investigated, which is designed to enable efficient energy conversion on the basis of Archimedes principle. In this investigation, the conversion efficiencies of two subsystems were calculated. The analytically calculated results provide a first estimate for the efficiencies of the two subsystems and can be further specified when a more detailed model of the plant is availabl

    Cultural practices of the reception and appropriation of films from the standpoint of a praxeological sociology of knowledge

    Der Autor untersucht aus der Perspektive einer praxeologischen Wissenssoziologie und mittels der dokumentarischen Methode die Aneignung und Rezeption von Filmen. Anhand des Spielfilms "The Others (2001) entwickelt er verschiedene Typen der Rezeption durch Jugendliche. Er befasst sich vor allem mit dem Typus der "produktiven Aneignung", bei dem sich habituelle Orientierungen der Jugendlichen in wichtigen Komponenten verändern. In einem empirischen Forschungsprojekt wurden hierzu 14 Jugendliche im Alter von 18 bis 22 Jahren nicht nur zum genannten Film, sondern auch zu ihrem Umgang mit Filmen allgemein befragt. Den Film "The Others" haben die Jugendlichen zudem schriftlich nacherzählt, ergänzt um den persönlichen Eindruck und das eigene Urteil. Der Autor bezieht die Nacherzählungen und die Interviews bei der Auswertung jeweils aufeinander und analysiert sie mit Hilfe der dokumentarischen Methode. Seine Ergebnisse verdeutlichen, dass Filme einerseits als Ressource für Gruppeninteraktion und soziale Beziehungen und andererseits als Ressource zur Welterfahrung dienen. Die letztere wird z. B. wirksam, wenn die von einem Film inszenierte Realität von Jugendlichen mit ihrer Alltagspraxis und ihren eigenen Orientierungen verknüpft wird. Der Autor diskutiert ferner Konzepte zur Zuschaueraktivität, vor allem sozialkonstruktivistische Ansätze aus der kognitiven Filmpsychologie, der systemtheoretischen Rezeptionsforschung und den Cultural Studies.
