    Evaluation of performance levels of students for moodle learning management system in terms of usability Criteria with PSI-Entropy-Marcos integration
    (2022) Yorulmaz, Muhammet; Can, Gulin Feryal
    The study, it is aimed to determine and compare the end-user performances within the scope of achieving the determined objectives while using the Moodle Learning Management System (LMS). Accordingly, considering multiple usability criteria, 18 users were prioritized in terms of their performances in using Moodie LMS. In this direction, Preference Selection Index (PSI) and Entropy integration was used to determine the importance weights of usability criteria, and the Measurement of Alternatives and Ranking according to Compromise Solution (MARCOS) method was used to prioritize the end-users. A new hybrid weighting method has been proposed by integrating the PSI method with the Entropy method, taking into account both the uncertainty in the performance values of the end-users according to the criteria and the preference change values of the criteria. This proposed method is applied for a three-dimensional initial decision matrix Thus, the traditional two-dimensional initial decision matrix which consists of the alternatives and the values that the alternatives take according to the criteria, has been developed and made more flexible. The objective criteria taken into account in the analysis were measured by the Morae V3 program, with the tasks defined as predetermined goals being performed by the users on the Moodie LMS. In addition, the criteria weights obtained from the proposed PSI-Entropy integration were used in the MARCOS method to rank the end-users according to their performance levels.

    Heuristic Evaluation of E-Learning
    (2018) Erenler, Hale Havva Turhangil
    As Knowledge Management applications, E-learning platforms have been used in many organizations. Universities as knowledge management appliers and early adopters of E-learning platforms as knowledge-sharing channels, making education independent of time and location, created new opportunities for students to become active and collaborative participants of their learning. In this respect, learning management systems offered tools and modules to facilitate knowledge construction, knowledge gathering and sharing among its participants. This study examined the critical factors of usability evaluation of the learning management system Moodle as part of students' blended learning in a computer literacy course at a funded University in Turkey. The model based on Nielsen's 10 heuristics and was tested with data from 236 students. Descriptive statistics showed that students generally agreed with the system and did not face problems when working with it. The study used structural equation modeling (SEM) for data analysis and found eight factors to be significant in the research model after an exploratory factor analysis. (C) AIMI Journals
