Özet:

This study presents a case study of the integration of usability evaluation into the development of task based information system prototypes in undergraduate software engineering course projects within a problem-based learning (PBL) approach. As part of the course, usability evaluation was integrated into the software development process, and the usability evaluation performance (UEP) of the projects was assessed in terms of the following criteria: effectiveness, efficiency and problem validity. It also analyzed the problem solution rate of the projects and their correlation between UEP criteria. Additionally, the study in-depth analyzed the students' final conclusions regarding the design process. The relationship between UEP criteria and the problem solving rate was examined using Spearman correlation analysis. In addition, final conclusions and problem solving behaviors were analyzed through document and thematic analysis techniques. The results supported that there is a significant correlation between usability evaluation criteria and problem solving rate. The main themes that emerged regarding usability problem solving behaviors were navigation design, error handling, database connection, algorithm design, search matching, system-user communication design and others. Final conclusions showed that project teams gained valuable insights into user-centered design, solved critical usability problems and improved their prototype design. It can be concluded that the integration of usability into software engineering education using the above approach contributes to students' understanding of user-centered interaction design.
