Utilizando monitoramento e atuação através de sistemas embarcados e móveis para a realização de experimentos em polarimetria

Abstract

Scientific experimental learning is vital to the students of different ages to understand the world and its problems. Nowadays, this is a complex problem for teachers in underdeveloping countries because good laboratories are expensive and access to them is not universal. Another problem about scientific learning is in motivate students to learn the concepts behind the practices. How can teachers help these students pay more attention to their laboratory activities and apply their knowledge in the real world? One answer to this question is to use alternative ways as open he006Cardware and software to create cheaper measuring instruments and different approaches to access them. The present paper has its primary objective to develop a didactic polarimeter of low cost and easy access for professors and students interested in Chemistry, Biology, and Optic Physics. The polarimeter's creation was used an open hardware platform called Arduino and the open-source software App Inventor to interface the user and the experiment. Finally, the evaluation of this work was done acceptance test with natural science teachers. The initial results were promising, showing a good functioning of the developed product and a good acceptance by the users.
