HIGH SCHOOL STUDENTS’ PERCEPTIONS OF THE USE OF THE BIOLOGY LABORATORY IN A PUBLIC SCHOOL

Abstract

This study analyzed high school students’ perceptions regarding the use of the Biology laboratory in a public school in Sobral, Ceará, Brazil. It is a descriptive field study with a quali-quantitative approach, conducted with 76 students from the 1st and 2nd grades. Data were collected through a structured questionnaire and a laboratory inventory. The results indicate that although the infrastructure is considered adequate by students, there is underutilization of equipment and limitations related to maintenance, expired reagents, and pedagogical planning. Practical classes are recognized as relevant, contributing to content understanding, increased interest, and the development of scientific skills. However, their frequency is irregular and concentrated in specific moments. It is concluded that there is a mismatch between the pedagogical potential of the laboratory and its effective use, highlighting the need to expand experimental practices and strengthen teacher training.
