This study aimed to develop a model for implementing e-learning with an omnichannel approach in secondary schools (second level) in Tehran. This research adopted a mixed-methods exploratory design. In the qualitative phase, semi-structured interviews were conducted with 16 experts in e-learning and educational technology, and data were analyzed using content analysis. In the quantitative phase, a sample of 256 teachers and administrators from secondary schools (second level) was selected through stratified sampling, and a Likert-scale questionnaire was distributed among them. Quantitative data were analyzed using structural equation modeling (SEM) in AMOS software. Qualitative findings identified key themes such as technology and infrastructure, security and privacy, content management, communication and collaboration, and user experience as critical factors for successful e-learning implementation. Quantitative results confirmed that the proposed conceptual model was statistically valid, with fit indices (TLI, NFI, IFI, RMSEA, etc.) within acceptable ranges. Significant factor loadings of the core themes demonstrated strong relationships between observable indicators and latent variables. The study concluded that implementing e-learning with an omnichannel approach requires enhanced technological infrastructure, adherence to security and privacy protocols, user-friendly content and interface design, and effective collaboration among users. The proposed model offers a comprehensive framework for improving the quality of e-learning in schools.
