Mobile learning, or m-learning, is defined as learning across multiple contexts using personal electronic devices. It allows students to actively participate in lectures from home in real time and continue learning activities anywhere at any time. M-learning delivers both formal and informal education through mobile technologies in a way that is context-aware and authentic for the learner. It enhances collaboration among students and makes courses more attractive by using communication apps, videos, and interactive displays on portable devices. M-learning also decreases training costs.
