This study is of a theoretical-conceptual nature and is a partial outcome of the research project VEGA MŠVVaŠ SR and SAV no. 1/0176/15. It deals with one of the problems currently faced by educational theory and practice, i.e. the foreign language education of seniors. The trend is typical for many EU member states, since it results from the needs of a modern society. In addition to strategic documents, programs and legislation which binds the Slovak Republic to create conditions for lifelong education, including foreign language education, the authors are more closely preoccupied with specificities and possibilities of the language education of seniors, which are explained on a comparative basis with the language education of children and youth. Even though in literature one can find results of many substantial empirical research projects devoted to foreign language education of children and youth, research into the education of adults and seniors in the area of foreign languages falls behind considerably. A sufficient platform for the methodology of language education of adults and seniors in Slovakia has not been created either, if compared with the methodology of language education of younger age categories. This shortcoming is often quite noticeable in practice. The study attempts to pay adequate attention to the analysis of selected teaching styles specific for adult and senior age as well as teaching methods which may be used in the language education of seniors.
