On the 24th of September 2019, Prof. Doris Holzberger took up the invitation to the LI Landesinstitut für Lehrerbildung und Schulentwicklung, literally the state institute for teacher training and school development) in Hamburg and gave a lecture at the LI Forum on "Transfer of Research Knowledge - Motivational and Emotional Development of (Prospective) Teachers". Prof. Holzberger’s scientific speech presented research results from the BilWiss research programme (click here for details) and a meta-analysis on top of the results of the working group "Research Syntheses" at the Centre for International Comparative Education Studies (ZIB). The joint discussion about the impact of the reported research results on teacher training and pedagogical action proved to be distinctly fruitful. With regard to the transfer of research knowledge, particular emphasis was placed on the importance of successful cooperation processes.
