Abstract
The tragic situation caused by the COVID-19 epidemic also became the biggest experiment in higher education. We sought the answer to the challenges arising at University of Tokaj with a higher education pedagogical experiment. The experiment was based on the practice-oriented design of cooperative learning, which was implemented through the joint project work of groups of different ages. The research question at the center of the experiment was whether the learning effectiveness of the groups participating in the experiment changed as a result of the completely on-line training during the COVID period. Based on deductive logic, the conclusion can be drawn that students active in the COVID period can be effectively educated within the “blended learning” methodology with an online-dominant training organization of up to 80%. The so-called COVID groups do not belong to a uniform age group, but to a group of students with the same history. In higher education, it is advisable to use the effect of the “spontaneous experiment” caused by the global tragedy of COVID as soon as possible, so that within the “blended-learning” method, the ratio of contact (classroom) and online training is between 20% and 80% we approximate to.
