Aplicação de sequência didática para o ensino de biotecnologia – transgenia

Abstract

Biotechnology is a very important topic for high school students, who seek to educate students to think critically about modern scientific technologies. This content is often challenging for educators who are faced with the difficulty students have in understanding the topic and the lack of pedagogical training of teachers. Therefore, it is necessary to think about new methodologies such as Digital Information and Communication Technologies (TDICs), which emphasize the leading role of students in teaching biotechnology. In an attempt to improve and facilitate learning about biotechnology content, this study developed a didactic sequence for teaching biotechnology – transgenics. The study was developed with 3rd year high school students from the “Frei Marcelino de Milão” State School, in the city of Iapu, Minas Gerais. The methodology was applied with a discussion group on the transgenic topic, bibliographic research on the topic and subsequent presentation of this research. A playful activity on the construction of the DNA molecule and presentation of the digital platform (OGM3D) were also carried out. As an evaluation method, an exhibition was presented through a science fair about transgenic technology. The results obtained showed that the students' prior knowledge about the topic - Transgenics - was scarce and superficial. The playful activity brought gains in learning, since the students were able to perceive the phenotypic changes after changes in specific codons in the DNA molecule. Finally, the application of the platform called OGM3D brought positive results, regarding the interest and perception for the development of transgenics. The science fair allowed the presentation of the proposed didactic sequence and the perception of the knowledge acquired by the school's employees and students. After the results obtained, it is concluded that the didactic sequence proposed in this study can be used as a model in the educational process, in the area of biotechnology-transgenics.
