This paper reports the investigation of the organisational structure of introductory sections of research papers written by Polish authors in English and Polish. The aim of the study was to test whether in view of cultural differences, reflected in the Anglo-American and Polish intellectual styles, the rhetorical pattern of research papers would vary between the two cultures. The selected texts were analysed in terms of Swales' Creating a Research Space (CARS) model (Swales 1990). On application of the model in the analysis of articles from the English corpus, it was found that it could only be employed in very generic terms. The analysis of the Polish corpus revealed that the Variation between Anglo-American and Polish schematic patterns was too significant to justify the implementation of the same investigative tool.
