Przemiany współczesnej retoryki wykładowej (na przykładzie praktyki akademickiej z historii)

The article describes differences between the theoretical model of academic lecture establi- shed in Polish linguistics and the conclusions drawn from the analysis of the corpus of authentic utterances. The language of academic lecture is determined mainly by the primacy of its didactic function. However, the results of the analysis demonstrate that the genre also comprises other communicative patterns typical, for example, of written academic discourse or the oral language. Thus the conclusions of the paper illuminate the ways generic models are constructed. The necessity to take into account authentic utterances and secondary communicative influences is strongly emphasized
