Aplicação das Técnicas de IHC para Avaliação de uma Ferramenta Complementar ao Ensino de Estatística

Abstract

This paper investigates the application of Human-Computer Interaction (HCI) techniques to evaluate and propose improvements in a complementary tool for teaching statistics, with a focus on usability. Considering the high dropout rates and difficulties faced by students in this discipline, basic functionalities of descriptive statistics were selected in the RStudio environment, using the Rcmdr package. The research adopted methods such as Hierarchical Task Analysis (HTA), heuristic inspection and Universal Design (UD) principles. Theoretical and inspection analyses revealed barriers to use in the current interface. Based on these results, a high-fidelity prototype was developed that incorporates the identified improvements, aiming to make the tool more intuitive and suitable for the educational context. It is expected that this proposal will contribute to facilitating the use of statistical resources by students, promoting more accessible and direct learning.
