Kit artesanal de microscopia para aulas de biologia celular no Ensino médio

Abstract

The objective of this work was to encourage protagonism in the study of cell biology and microscopy through the construction and use of a low-cost handmade microscopy kit made by public and comprehensive high school students. For this, an investigative cycle with five phases was carried out: Orientation, Contextualization, Research, Conclusion and Discussion. The students also answered a questionnaire on knowledge about cell biology and microscopy. At the end of the activities, the students answered a questionnaire to evaluate the pedagogical strategy adopted in the work. For the analysis of the participants' answers, they were organized into a text corpus using Microsoft Office word 2010 software and the necessary adaptations were made for content analysis in the thematic modality using the software IRaMuTeq version 0.7 alpha 2 and the software "R" version 4.1.2. The results of the first questionnaire were presented in three thematic classes: Identification with the scientific practice; Concept of cell in the view of high school students and Initial conceptions about microscopy: focus, illumination and magnification. The results of the second questionnaire were presented in three thematic classes: Experience with the activity; What it takes to create a microscopy kit and Concept of the cell in the view of high school students. The pandemic of COVID-19 made it difficult for some students to participate because they did not have access to the internet, did not have the necessary equipment, or were still working to help their families. All participants judged the activity positively, also stating that it was good for the study, especially because it was a practical activity. As an educational product, among the microscopy kits produced, the one that in the students' view is the most appropriate for use in biology classes was chosen. There was an incentive to the students' protagonism, who were able to investigate more deeply the universe of cell biology and microscopy.
