Biotecnologia e vacinas: uma sequência didática, em ambientes virtuais, no processo de ensino e aprendizagem de biologia

Abstract

The current scenario has made virtual work almost mandatory and, therefore, of great importance to teachers and students. The teacher, when looking for didactic resources, can use those that make it possible to transpose his class out of the physical environment to the digital environment, using technological resources and tools in the form of VLE (Virtual Learning Environment). The choice of topic was based on the importance that the subject of vaccines and biotechnology presented as it is considered a high priority due to the devastating effects of COVID-19 and allows the student to share their views, opinions, etc. The biotechnological process has contributed decisively to the improvement of processes related to the development and production of new vaccines or the improvement of existing vaccines, so that they become safer and more effective. The vaccine is a suspensionor fragments of organisms used to induce immunity and therefore reduce the spread of infections and the occurrence of epidemics. Although vaccination is important in the control of the infectious diseases, several studies show insufficient knowledge about vaccines and diseases against which they protect. The present study had as general objective to promote the use of ICTs in the remote teaching of Biology, with the content biotechnology, theme vaccines, in the 3rd year of High School, through a didactic sequence (SD), using tools available on Google, such as pedagogical resources for content dissemination. The activities included the screening of a film, complementary texts for research, an interactive game, classes with active and investigative methodologies and structured debate. Several qualitative approaches were carried out, through questionnaires, using the virtual resources WhatsApp, Google Classroom and Google Meet. The work was carried out at Colégio Municipal Rio Branco, located in the municipality of Visconde do Rio BrancoMG, where students from the third grade of high school participated. In addition to bringing greater knowledge to students on the subject, it was possible to verify that the SD presented a positive aspect in the learning of biotechnology content. According to the qualitative questionnaires, the students classified the activities as interesting, attractive and dynamic, claiming that it caused an increase in interest in the content. Some information obtained during the activities was transcribed, allowing the analysis of the answers, making it possible to observe the benefit of the methodology used in the acquisition of knowledge by the participating students, in additionto favoring greater participation than traditional classes. In addition, it was possible to examine questions on the subject more effectively, sharpening students' curiosity and autonomy in the search for their own knowledge. The purpose of the product was to facilitate the teaching and learning of this topic, since the current scenario of the Covid-19 pandemic is a favorable moment to delve into this content. After analyzing the results, it was concluded that the elaborated didactic sequence can be applied, with quality, being an interesting support material for teachers and students.
