Computerbasierte Lehrund Lernsysteme sollen Wissen effizient vermitteln und den Umgang mit Problemen in Prüfungssituationen oder im Alltag vereinfachen. Damit das Gelernte in aktives, anwendbares Wissen (prozedurales Wissen) beim Teilnehmer umgewandelt wird, reicht die bloße Vermittlung von Fakten und Regeln (deklaratives Wissen) nicht aus. Die Anwendung des Wissens selbst muß in „realen“ Probl...

The software engineering community has recognised the need for integrated project support environments (IPSEs) for some time. With such a system the user is provided with an integrated set of software tools with which to operate. Given this set of integrated software tools rather than a set of ad hoc tools the cost of software and project support throughout its life cycle is reduced. The techni...

Although sperm are typically thought to be small, tadpole-like cells produced in vast quantities, sperm size, form and number all vary tremendously across species. Sperm form ranges from amoeboid or discoid to multiflagellate elongated structures [1]. Even within the more familiar uniflagellate spermatozoa, length varies by several orders of magnitude, from the tiny 28μm long porcupine sperm to...

We discuss four interconnected issues that we believe have hindered investigations into how language may affect thinking. These have had a tendency to reappear in the debate concerning linguistic relativity over the past decades, despite numerous empirical findings. The first is the claim that it is impossible to disentangle language from thought, making the question concerning "influence" poin...
