Uso de programação com o Scratch para a busca de evidências de aprendizagem significativa no ensino de juros simples para o 9º ano

Abstract

This dissertation aimed to apply a didactic sequence using Scratch computer programming, aiming at significant learning in teaching simple interest for the 9th year of elementary school. Furthermore, it was specifically intended to present computer programming as a learning process, explore teaching-learning processes of simple interest and Scratch programming, identify students' subsumers (prior knowledge) according to financial mathematics, develop and apply a educational product in the form of a didactic sequence using Scratch computer programming aimed at teaching simple interest and verifying whether in the application of the educational product, there was evidence of significant learning. In view of this, it brought up the problem of analyzing how the use of programming with Scratch enhances student involvement in order to verify the existence of significant learning in the teaching of simple interest in the 9th year of elementary school. The educational product entitled Teaching simple interest with Scratch programming intended to address, during ten hours/class, the teaching of simple interest through Scratch programming, for exactly 06 students, distributed in classes of the 9th year of Elementary School, in a school in city ​​of Chupinguaia/RO. The study was premised on what governs the National Common Curricular Base (BNCC) and was based on Papert's theory of constructionism, together with the concept of computational thinking. Therefore, the research brought a qualitative research approach to the participatory research procedure. For data collection, a diagnostic questionnaire was applied in order to test the students' prior knowledge, in addition to considering the teacher/researcher's logbook and the screen prints with the production of the Scratch programming developed by the students. The results showed that there was evidence of significant learning using programming with Scratch in teaching simple interest for the 9th year, since the students involved, at the time they developed problems related to simple interest, also learned Scratch programming in a intuitive and fun way. The educational product is available on the educational products portal of the Postgraduate Program in Science and Mathematics Teaching, at the University of Passo Fundo, and on the EduCapes website
