Investigating Graphical User Interface Design principles for designing Iranian educational mobile applications

E-learning tools should be developed based on learners' psychology. Many studies have been conducted on the nature of learning and the factors affecting it. One of the psychological issues that should be considered is the user interface in E-learning because the user interface (UI) is the point of interaction between the user and the learner. The user interface influences the possibility of using an application and the ease of learning. If such correlation fails, the training objectives may not be achieved, even if the training content is well chosen and the user is willing to learn. For this reason, the main issues in successful collaboration, which should be considered in designing user interfaces for E-learning and educational applications, are the focus of this study. This research aims to investigate the rules of graphic user interface design for the design of Iranian educational applications. The research method is a descriptive survey, and the data collection methods are library-based and qualitative. One hundred educational applications published in the Google Store, rated between 4 and 5, have been examined in this study. These applications have been reviewed regarding overall design style, fonts, primary colors, icons, and more. Also, a questionnaire was designed to know the importance of each item from the audience's point of view, and it was distributed among 169 people, and its results were analyzed and checked using SPSS. The results showed that successful applications use similar design styles, fonts, colors, and icons, which can be used as a suitable model.
