Experimentation as an active methodology in teaching and learning genetics

Abstract

This work reports on an experience about the importance of practical classes in the process of teaching and learning genetics. The study was conducted in the form of an experience report based on the experience and observation of a practical DNA extraction class in the Biology discipline in the 3rd year at a public institution in the city of Paracatu – MG. The pedagogical intervention was carried out in six Integrated High School classes during two classes (100 minutes). During the practical class, the methodology used was participatory, which allowed students to act effectively in the educational process without considering them mere recipients. Throughout the practical classes, the teacher observed and noted the students' behavior regarding understanding and execution of the activity, participation, teamwork, etc. The students' learning was assessed through discussions during the experiment and the questionnaire they answered at the end of the practical class. In view of the above, it was possible to observe the importance of the practical class as a methodological tool in the Biology discipline to approach genetics. Among the main advantages highlighted by the students is the greater retention of the content that was previously seen in the theoretical classes.
