A matemática e os códigos de barras: uma proposta de ensino

Abstract

Barcodes can be an important tool to stimulate the learning of math, because they are extremely used everyday. With that in mind, this work has as it general objective to analyze the comprehension of the main characteristics of barcodes and the motivation of 9th grade students of the elementary school of the Marcílio Dias Municipal School, in Nova Iguaçu-RJ. Initially, we approach the concept of motivation, its different types, motivational strategics and its importance in the learning process. In sequence, we define some math concepts that they need to understand the math behind the barcodes. Then, we describe the barcodes structures, specially of the EAN-13 barcodes. We also briefly present the QR Codes. Lastly, a qualitative approach is made based on the evaluation of diversified activies and of research instruments, seeking to identify the school motivation and math motivation of those involved. This work demonstrates that is possible to motivate students in their teaching-learning processes by contextualizing math, through barcodes
