Research methodology in special needs education in the concept of professor Aleksander Hulek

Summary/Abstract: The article presents an analysis of research methodology in special needs education as presented by Aleksander Hulek in 1983 in relation to the current research. The article contains Professor Hulek’s scientific achievements, as well as the theory of common and specific factors in revalidation. Methodological assumptions, as presented by Aleksander Hulek were applied in research conducted to verify the theory as specified above. Professor Hulek specified four stages of scientific research development in the field of special needs education, however only the last of them, in his opinion, met the conditions of research objectivity. He suggested a model of comparative studies, taking into consideration both the control group and a representative selection of subjects as well as using qualitative measurement. Now, after thirty years, the specified stages should be understood as approaches to research and each of them has been developed and is still applied. The suggested model is still used, although it has some limitations.
