This master thesis deals with the concept of autonomy and the focus is given to the self-assessment techniques. The theoretical part first introduces the idea of autonomy and various techniques which can help with the development of autonomous learning. Next, the theoretical part stresses the importance of the learner-centred classroom and introduces the constructivist theory. Aims are another substantial part of autonomous learning; therefore, one chapter is investigating the typology of aims. What follows is the classification of assessment and self-assessment. The theoretical part ends with the introduction of different techniques of self-assessment. The practical part presents a case study which investigates how the self-assessment of primary learners happens in English lessons. Several research tools are used to answer the research question.
