The primary objective of this thesis is to conduct an evaluation of user experience within a specific case study – the online learning environment Umíme (umimeto.org). The evaluation will employ qualitative methods, including semi-structured interviews, usability testing, and observational studies. The evaluation will encompass user testing and interviews involving various user groups within the learning environment (teachers, students in a classroom setting, and individual learners). The findings of the evaluation will be synthesized into specific recommendations for future development of the system.
