Bioacústica de anuros e sua importância ecológica: apresentação da temática como instrumento de ensino em turmas de biologia do ensino médio

Abstract

Anurans belong to a group of vertebrates of great relevance in an ecosystem, as they are bioindicators and biocontrollers. Given the above, this work aimed to describe and analyze the efficiency of a differentiated methodology in the study of frogs and their vocalizations in a high school in Urucuí-Pi. The methodology used was based on a qualitative and quantitative research, using a lecture on the importance of anurans ecology and types of vocalization and its importance for species recognition as well as for attracting females during the reproductive period. A semi-structured questionnairewith 10 questions was applied and to end the class, the students were taken to the bioacoustics booth. The results showed that the students had a certain level of knowledge that allowed them to have a minimum percentage of error. In the questions that asked about vocalization, after the didactic intervention associated with the bioacoustic box, the answers in the questionnaires were more elaborate in relation to the answers in the pre-questionnaire. Based on the objectives, it was observed that the students were able to give more precise answers after the didactic interventions, in addition to the fact that the bioacoustic cabin brought a good result associated with the class. It was observed that the students were able to understand the ecological importance that frogs play in nature. Thus, this research proves to be relevant in this process of knowledge construction in a differentiated wayg
