Aprendizagem colaborativa: construção de modelo do sistema cardiovascular humano associado à robótica

Abstract

Educational technologies bring many possibilities and should be used to contribute to the teaching-learning process. The Arduino platform is very efficient in the educational process and because it is flexible it can be used on practical occasions or more complex projects at different levels of education. In the construction of models based on collaborative learning, it is the students, mediated by the teacher, who perform the production of this didactic resource. The cardiovascular system presents a certain degree of abstraction and a large amount of specific information, the difficulty of assimilating knowledge, this process can be facilitated by alternative methodologies. The present work aimed to build, in a collaborative way, a didactic model of the cardiovascular system of the human body associated with robotics, using the Arduino platform as a tool. This construction was carried out by students through a project at a state school in Água Doce, Maranhão. An investigative teaching sequence (SEI) was developed and the dialogues between students throughout the project were recorded by audio recordings. A questionnaire covering basic knowledge about the cardiovascular system was applied before and after the project and its data used to ascertain the evolution of learning through the hake equation. The students developed the stages of the project in a participatory and committed way, suggesting and materials for the model, which had a base made of expanded PVC and the cardiovascular system simulated by hoses and hydraulic pumps associated with a construction relay and ultrasonic sensor. SEI has positive results in the development of learning about the cardiovascular system, being one of the products of this research, the other was the didactic model together with the programming codes for Arduino.
