Uso da robótica educacional aplicada ao ensino de química

Abstract

The present work attempts to combine educational robotics with chemistry teaching, in an attempt to mitigate two guiding problems, 1st the low level of student engagement in chemistry classes, 2nd the reduction of the workload for the chemistry subject with the new high school, with objectives in addition to those mentioned above: Developing a didactic sequence, guiding the construction of seminars and finally preparing an e-book containing the didactic sequence (SD). The research was developed in three stages. The first was to carry out an active search in periodicals from 10 A and B quality magazines in search of articles focused on the use of robotics applied to chemistry teaching. In this search, 5567 articles were evaluated, of which only two were within this threshold. The second stage was the elaboration of an SD with its subsequent application in a 2nd year high school class at the State school located in Boca da Mata, in the interior of Alagoas. SD is made up of seven moments, they are: 1 - division of groups and choice of projects to be developed. 2 - 1st questionnaire on Google Forms and class on the Canva platform. 3 - assembly of kits for construction of projects and monitoring of slides, 4 - beginning of construction of prototypes and monitoring of construction of slides, 5 - Finalization of prototypes with subsequent programming and monitoring of slides. 6 - culmination of work and final presentation, 7 - 2nd questionnaire on Google Forms. The third and final step was the application of SD. With the use of the methodology, it was possible to observe a significant increase in correct answers when comparing the two questionnaires made on Google Forms, such as the 3rd question which deals with the Chemical explanation of the phenomenon, before SD 41.7% of students opted for the alternative correct, and after applying SD the percentage became 79.2%. In the process of building the two prototypes, line follower and light follower, and a seminar developed and presented by students on the Canva app at the end of the work, it was observed that there was greater student engagement in the development of the subjects worked on by each project.
