The purpose of this text is to identify the main strategies of the teaching-learning process, as well as the perceptions of professors during the period of social isolation in the context of the pandemic generated by Covid-19. The study sample consists of 52 professors from the Administration, Accounting, and Economic Sciences courses, working in four higher education institutions in the southern region of Brazil. The survey carried out through a questionnaire comprising 32 questions, collected the respondents' identification, the perceptions of the teaching process, and the teaching-learning strategies used from the insertion of classes remotely as an alternative in the social isolation period. As data treatment, descriptive statistics, and the Mann-Whitney statistical test were used, the analysis is quantitative. The results show that, for 96% of those surveyed, the disciplines took place remotely; 92% indicate pedagogical adaptations, and 76% responded that the institution offered training. The main teaching strategies used in the period of social isolation are: expository classes with the presentation of content on slides (98%); exercises with resolution (90%); case study (69%); and content-oriented research/reading (52%). The statistical analysis shows that professors who used problematization/teaching cases, debates, and games believe they have achieved the teaching-learning objectives. In the perception of 54% of professors, classes held remotely do not represent losses in students' teaching-learning process and have achieved their objectives. In general, the results demonstrate adaptation of face-to-face classes to the remote format. The findings suggest the importance of inserting technologies as teaching strategies, regardless of whether the model is face-to-face or not.
