Forschung in der Lehrerbildung

Beiträge zur Lehrerinnen- und Lehrerbildung, 1998
Die Lehrerbildung hat bislang kaum eigene Forschung betrieben und auch kaum Forschung nötig gehabt. Die Tertialisierung der Ausbildung legt einen Forschungsbezug nahe, er macht wesentlich die Unterscheidung zur bisherigen Ausbildung aus. "Forschung" ist
