Adopt a Bacterium: a professional development opportunity for teacher assistants.

Science teaching in most Brazilian Universities tends to focus mainly on lectures and provides few opportunities for the development of modern teaching skills. Our group developed an online tool called Adopt a Bacterium, which consists on a Facebook group where teacher assistants (TAs) can interact with students and have a first contact with student-focused learning approaches. This work shows the TAs' own assessment of how the tool could be further explored to help them develop skills and become better teachers. © FEMS 2020.
