GUERRA SALCEDO, Marisela de la Caridad    MENDEZ SANTOS, Isidro Eduardo. Development of analytical keys; alternative for the learning of biology. []. , 18, 85, pp. 7-14.   02--2022. ISSN 1990-8644.

A procedure to guide the elaboration of analytical keys is socialized, as an alternative that guarantees learning from subjects that deal with contents of biological systematics, in biology teachers in training. The arguments that support the use of keys are systematized, their potentialities are revealed and the meaning for this has not only the use of those in force in specialized literature or those created by the teacher, but also their elaboration by the students, as approach of a problem to solve in the subjects of systematic cut. The procedure consists of three moments: assurance of the preconditions, elaboration of the key and evaluation of the results achieved, with emphasis on self-evaluation.
