Abstract

The paper analyzes how to improve the teaching of Operational Research, focusing on distance learning courses where professors and students are separated through space and time. This case study was done in a public Industrial Engineering undergraduate course, and the work structure is divided into three main parts: an exploratory-descriptive documentary analysis, application of free software, and evaluation of learning. The authors showed the feasibility of using the SageMath tool in the teaching-learning process. The study revealed the importance of developing alternative solutions to educational realities marked by economic and financial constraints, where structure teaching with free software is a ruling factor once Engineering education is not a similar global event everywhere. Distance learning is a phenomenon that has been growing over the last 20 years in Brazil, but this was one of the first experiences with the use of SageMath. So, it can serve as a reference for countries with socioeconomic conditions similar to Brazil. Also, this case study can help other professors to enhance their teaching in a distance learning context even in scarcity scenarios of educational resources. The software implementation would be justified in part of the groups studied.

在线运筹学教学建议：巴西 SageMath 的经验

本文分析了如何改进运筹学教学，重点是教授和学生在空间和时间上分离的远程学习课程。该案例研究是在一门工业工程本科公共课程中完成的，工作结构分为三个主要部分：探索性描述性文献分析、免费软件的应用和学习评价。作者展示了在教学过程中使用 SageMath 工具的可行性。这项研究揭示了针对以经济和财政限制为特点的教育现实开发替代解决方案的重要性，一旦工程教育不是一个随处可见的类似全球事件，使用免费软件进行结构教学就是一个重要因素。远程学习是巴西在过去 20 年中不断发展的一种现象，但这是使用 SageMath 的首批经验之一。因此，它可以为社会经济条件与巴西相似的国家提供参考。此外，即使在教育资源匮乏的情况下，本案例研究也能帮助其他教授在远程教学中提高教学水平。在所研究的部分群体中，软件的实施将是合理的。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
