QuatiView 2.0: nova versão de um software de visualização de algoritmos a partir de avaliação de usabilidade

Abstract

Algorithms and data structures are fundamental subjects in the field of Computer Science; however, the abstract nature of these concepts poses a challenge for students. In this context, algorithm visualization software serves as a complementary resource to traditional teaching methods, contributing to the connection between theory and practice. In 2021, a Computer Science student at Unioeste, Foz do Iguaçu campus, developed QuatiView, a web-based algorithm visualization tool designed to support the teaching and learning process of algorithms and data structures. This research aimed to propose the development of version 2.0 of the tool based on a usability evaluation. To achieve this, an analysis of similar tools and a systematic literature review were conducted, resulting in the development of a questionnaire adapted from the System Usability Scale (SUS). The application of the questionnaire to Computer Science students at Unioeste and expert professors in the field made it possible to measure a usability score of 84.26. Based on suggestions for improvements and new features provided by the participants, a list of functionalities and enhancements was defined and included in version 2.0 of the tool.
