The study focuses on improving e-learning effectiveness and its implementation during the COVID-19-induced lockdown. The study involved 328 students aged 20 to 24 years with an equal number of males and females. Research shows that e-learning is mostly used together with embedded pedagogical tools and technologies rather than single training programs to improve the quality of teaching based on a unified method. Constructivism is an effective approach for this purpose. The research results can be used in programs with embedded learning elements based on constructivist pedagogy in online and blended learning at higher educational institutions.
