Abstract The current SARS-CoV-2 pandemic gave rise to a spirit of methodological anarchy in some fronts of biomedical research, embraced by some under the excuses of urgency and time restraints. This movement, however, comes at the same time when social sciences begin to recognize the value and soundness of the clinical research rationale - the need for randomization, of fair comparisons between intervention groups, the humility of acknowledging ignorance and accepting uncertainty, these last two imperatives usually subsumed under the principle of “equipoise”.

ABSTRACT The “Adopt a Bacterium” project is based on the use of social network as a tool in Microbiology undergraduate education, improving student learning and encouraging students to participate in collaborative learning. The approach involves active participation of both students and teachers, emphasizing knowledge exchange, based on widely used social media. Students were organized in groups and asked to adopt a specific bacterial genus and, subsequently, submit posts about “adopted genus”. The formative assessment is based on posting information on Facebook®, and the summative assessment involves presentation of seminars about the adopted theme. To evaluate the project, students filled out three anonymous and voluntary surveys. Most of the students enjoyed the activities and positively evaluated the experience. A large amount of students declared a change in their attitude towards the way they processed information, especially regarding the use of scientific sources. Finally, we evaluated knowledge retention six months after the end of the course and students were able to recall relevant Microbiology concepts. Our results suggest that the “Adopt a Bacterium” project represents a useful strategy in Microbiology learning and may be applied to other academic fields.
