In order to obtain empirical evidence on the formation of professional and technical competence in microbiology among students in biological and pharmaceutical chemistry, a quasi-experimental study was carried out in a practical course on Experimental Microbiology. Three types of interventions were tested at various times during the course: a) professor's lecture, b) demonstration of technique, and c) an instructional video. The study's general results showed statistically significant differences (p<0.05 and p<0.01) in favor of the use of the video. Thus the conclusion can be made that this teaching strategy, applied at two different times in the course (instructional session and reinforcement session) and supplemented by evaluation, favors the attainment of professional and technical competence among students in biological and pharmaceutical chemistry.
