Assessment of a method for usability testing by determining usability of the online learning platform

Abstract

Today many products are designed to be reasonably easy to use so, in addition to usefulness, product usability is of great importance. Usability means simply using or simply learning to use a tool or device. In software engineering, usability is the degree to which certain users can effectively use software to achieve their goals in the context of use. Usability assessment involves measurement methods, such as analyzing consumer needs and examining perceptions of product efficiency and product attractiveness. In human-computer interaction, studying usability means the analysis of attractiveness and clarity of an application which is designed to interact with a computer program or web site. Usability takes into account both user satisfaction as well as the usability and quality of the component under study, while striving to improve the user experience through iterative product design. The basic problem of the research project was the pilot assessment of the suitability of our own method of testing the usability of the Sakai online learning platform in integration with the BigBlueButton conference call program. The article presents the most important results of assessing our own method of testing the usability of the learning platform on groups of students and lecturers participating in the e-learning process and project (CPK) testers. The testing was performed on the basis of the evaluation of the test subjects' introspective insight into their own expression of emotional reactions by means of a questionnaire and analysis of mimics, gestures and proxemics from the videos of the test subjects by the testers. The statistical significance of the differences between the groups was performed by Kullback 2Ȋ test of the independence hypothesis.
