The research purpose is to analyse the self-regulation of students who use the massive open online course (MOOC) technology to learn the exact sciences. The sample included 252 students: females were 47%, and males were 53%. The average age of students was 20.08 ± 0.72. The students were divided into two groups: group 1 consisted of students who learnt the Digital singular (nano) optics course online using the MicrosoftTeams platform with teacher's support; group 2 consisted of students who learnt the MOOC course individually. The relationships between self-regulation and academic success were also analysed. The research found that the overall level of self-regulation of students using MOOCs was 40% higher. In students who learnt online using the MicrosoftTeams, the level of self-regulation was average and amounted to 24.96 ± 1.32. In students who learnt the course based on the MOOC technology, the level of self-regulation was high and amounted to 35.02 ± 1.44 (p < 0.05). The research of self-regulation shows higher results among the students who learnt using MOOCs platforms: flexibility -- 46%, planning -- 23% and results assessment -- 15%; modelling and programming were no different. The average success score of students after learning the course on the MicrosoftTeams platform was 3.83 ± 0.36, and in the MOOC group, it was 4.43 ± 1.89.
