The aim of this study is to describe the typology and content of future foreign language teachers’ mediation and communicative-interactive skills to visualize the educational material in a foreign language lesson at school. The work presents the definitions of the concept of ‘visualization of educational material’ and related concepts of ‘non-continuous text’, ‘multimedia text’, and ‘multimodal text’. The visualization of the educational material is considered in the framework of professional and communicative competence of a foreign language teacher. The scientific novelty of the study lies in the typology of mediation and communicative-interactive skills to visualize educational material in accordance with mediation and presentation strategies, a description of communicative tasks solved in terms of visualization of educational material, and the main mistakes of teachers in the implementation of these tasks. As a result, we assume that the skills of visualizing linguistic material correlate with professional and communicative strategies of mediation and explanation of educational material and require purposeful development, taking into account the key principles of competence-based, communicative, and sociocultural approaches, solved educational tasks, level and age needs of learners, principles of selection of material, cultural value of the visual sources used, and other parameters.
