Design de interação no Moodle Mandacaru: análise da usabilidade e arquitetura da informação do ava Moodle no formato Mandacaru

Abstract

This papers objective is to evaluate the usability and the information architecture of the Moodle Mandacaru interface, now being utilized in the Center for Studies in Public Health in the Federal University of Rio Grande do Norte (UFRN). Specifically in the Specialization Course in Labor Management and Health Education (CGTES), and to propose improvements for future versions. The study was based on the concepts of usability evaluations using predictive techniques, using ergonomic criteria for inspection via checklist LabUtil, and prospective, using the cooperative evaluation and satisfaction questionnaire. The research methodology is descriptive and its mixed approach, in which are utilized quantitative analysis, collected in satisfaction questionnaires and interpretative analysis, collected in interviews on site with 5 students of the course. To help in the organization and direction of the research it was used a framework called DECIDE, where a specific sequence of orientation, execution and analysis in the evaluation process was drawn .Data collection was organized in three stages: (1) the preparatory phase, the organization of actions that will guide the subsequent steps; (2) the first stage, with the realization of a diachronic analysis of the object under study and ergonomic inspection; (3) the second stage, with the implementation of cooperative evaluation coupled with the satisfaction questionnaire. Data analysis in the first stage, through environmental diachronic analysis showed a significant improvement in visual appearance, content organization and use of new technologies in previous versions, however the inspection via checklist presented a percentage of approximately 33% non-compliance with the ergonomic criteria in Ergolist, presenting flexibility, user control, feedback and minimal actions as one of the interface problems. The results of the second step showed a consistent with most points of the previous stage, adding a personal touch user satisfaction with regard to usability and aspects relevant to the environment.
