Online learning platforms have become integral to modern education, especially during the COVID-19 pandemic, as they offer a dynamic environment for remote education. This study focused on evaluating postgraduate students' and Ph.D. scholars' perceptions of online learning platforms at the Vel Tech Rangarajan Dr. Sagunthala R&D Institute of Science and Technology, School of Management Studies. Employing a descriptive research design, this study utilized convenience sampling and distributed a Google Forms to 218 students in March 2023. In total, 104 responses were received. However, 101 questionnaires were found to be valid and fit the analysis. The study used a five-point Likert-scale questionnaire to collect data on students' perceptions of four factors (educational system quality, information quality, ease of use, and usefulness). The study employed statistical packages for social sciences (SPSS) and SmartPLS4 were used for data analysis. The study used data analysis techniques such as descriptive statistics, Pearson correlation, construct reliability and validity, convergent validity, outer loadings, R-square, and f-square to evaluate the reliability, data quality, and fitness of the model. Apart from that, path coefficient was run to examine the level of influence of the independent variables on students' perceptions. The findings supported the hypotheses related to the positive correlation between educational system quality, ease of use, and overall satisfaction with online learning. However, this study challenged the hypothesis that information quality significantly affects student perceptions of online learning. While this study did not provide strong statistical evidence for the positive relationship between the perception of information quality and students' intention to attend online learning sessions, it highlights the importance of ensuring high-quality educational materials and considering other factors that influence students' decisions in online learning. The findings suggest that focusing on these aspects can enhance student satisfaction, engagement, and motivation in online learning environments. Moreover, educators and institutions should capitalize on the unique advantages of online learning, such as flexibility and multimedia-rich content. In conclusion, this study provides valuable insights into the complex interplay between students' perceptions of online learning platforms and their intentions and behaviors. The implications discussed offer guidance to educators and platform developers to enhance the design, implementation, and effectiveness of online learning experiences. This study also identified future research directions, emphasizing the need for more comprehensive studies, considering additional predictor variables, incorporating qualitative data, and conducting longitudinal research.
