Do artesanal ao tecnológico: desenvolvimento de material para o ensino sobre o DNA com modelo de impressão 3D

Abstract

This work proposes the use of 3D printing as a pedagogical resource in conjunction with the production of didactic material for teaching the structure of DNA, offering an interactive and accessible approach. The proposed model can be adapted for elementary and high school (middle and high school) curricula, complementing theoretical instruction with practical activities, such as the assembly of DNA, which stimulates active participation and the development of perceptions regarding the complexity of the structures and chemical bonds present in the DNA molecule. The research also addresses, as main themes, the contributions of Rosalind Franklin, the model proposed by Watson and Crick based on Photograph 51, and the production of some basic materials representing the DNA structure. The use of modeling software, such as Thingiverse, Printables, and PrusaSlicer, allows for the customization of the models, making the resource even more flexible. This technological approach can enrich the teaching of genetics, promoting a shift from traditional teaching dynamics to active and visual learning.
