The search for meaningful learning continues to be a challenge for many teachers, who
need to plan their classes with the objective of achieving teaching that meets the needs
of students. This work aimed to propose a didactic sequence for the teaching of
"cytology" in the 1st year of high school, based on the Theory of Didactic Situations
(TSD), having as a starting point the use of a homemade microscope. The methodology
involved a qualitative and bibliographical research, seeking to suggest a teaching model
based on TSD, which consists of the application of four phases: action, formulation,
validation and institutionalization. The proposal is promising and can be applied in
different curricular contents.
