Purpose
This study aims to identify the most important factors affecting the usability of Learning Management Systems (LMSs) and present these factors in the form of a comprehensive and practical framework and validate the framework.

Design/methodology/approach
In this research, a mixed research method and sequential exploratory research design were used. In the qualitative section, the qualitative meta-synthesis method was utilized to extract usability factors from the research literature and formulate the framework of factors, and in the quantitative section, the survey method was employed to validate the framework. In the qualitative section, the research field included the research available in the Scopus and Web of Science databases, and the data collection tool included electronic and printed documents on the usability factors of LMSs. To validate the findings, in addition to citing research literature and theoretical foundations, the audit trail, consensual validity and expert peer review methods were used. Also, to analyze the data, the thematic analysis method and thematic network via MAXQDA 2020 software were used. In the quantitative section, the statistical population was students of the Faculty of Psychology and Educational Sciences at Allameh Tabatabai University in Iran, and the sample included undergraduate students of this faculty with a volume of 200 people. The tool for collecting information was a researcher-made questionnaire that was provided to students in the first half of the academic year 2022–2023. To validate the findings, content-related validity through Content Validity Ratio (CVR) and Content Validity Index (CVI) and construct validity through Confirmatory Factor Analysis (CFA) and Convergent Validity were examined. Cronbach’s alpha coefficient and Composite Reliability (CR) were also used to check reliability. To analyze the data one-sample T-test via SPSS 27 software was used, and the PLS-SEM was utilized via SmartPLS 4 software to validate the framework proposed by the researcher.

Findings
The findings from the qualitative part of this research include basic themes and organizing themes related to the global theme of usability. Based on the findings from the qualitative part, it can be concluded that the factors in terms of frequency in the research literature have the following ranks: interaction (first rank), ease of use and usefulness (second rank), learnability (third rank), navigation (fourth rank), satisfaction and enjoyment, visual design and accessibility (fifth rank), help and assessment and feedback (sixth rank) and content, errors correction and privacy and security (seventh rank). The findings of the quantitative part include the external fit indexes of the framework and the internal fit index of the framework; based on the obtained values, it can be concluded that the framework of LMS usability factors has a good fit.

Research limitations/implications
This research is the first comprehensive study of all theories on the usability of LMSs, in which a framework is proposed that combines the important factors mentioned in the relevant theories and models for the first time. Additionally, practical and applicable suggestions are provided in this study to enhance each of the usability factors of LMS.

Originality/value
To the best of the authors’ knowledge, this research presents a framework for the first time in which all important factors of usability theories and models are combined and prioritizes these factors based on their importance in relevant research. It also provides practical recommendations for enhancing these factors in LMSs for system developers and instructional designers.
