Resumo
The objective of this study was to evaluate the effectiveness of the use of homemade microscopes built by students, using low-cost and easily accessible material, as a didactic tool for learning in science, in order to enable a meaningful understanding of cells. The research was developed with 50 students of the 8th grade of Elementary School of a municipal public school located in the state of Espirito Santo, in the city of Sooretama. Therefore, the research begins from the difficulties encountered to carry out a work in Elementary School, which seeks to lead to the understanding of cellular functioning in a school devoid of microscopes and science laboratory. The research consisted of retrieving previous knowledge, teaching sequence applied to reinforce learning, making homemade microscopes, discussion and socialization of knowledge and post-test application to evaluate the acquired learning. A selection was made and three models of microscopes were chosen and were built by the students using easily accessible materials, based on articles found in the literature. The models built were: low-cost microscope using CD cover and mobile device, microscope with pet bottle and microscope with cardboard box and mobile device. After the construction of the models, observations were made of plant and animal cells, such as onion epithelium, pepper epidermis cells, cheek mucosal cells, cajá flower, among others. The microscope built with a CD cover obtained more positive results. In general, the results showed that after applying the proposal, the students were able to elaborate their answers in an affirmative way, and it is clear that the activity developed was very significant and that the participants understood more about the subject of Cell Biology. With the methodology applied through this research, it was possible to develop more dynamic and attractive classes for students, favoring the understanding and learning of the content that was being worked on, making the student the protagonist of the learning process
