M-learning refers to learning that takes advantage of portable technologies and can occur anywhere, allowing for "anytime, anywhere learning." It involves interaction with tutors, learners, and content through mobile devices like smartphones, tablets, and e-readers. While m-learning provides benefits like increased motivation and student-centered learning, it also presents challenges such as potential distraction, cheating, and ensuring device compatibility and durability. For m-learning to be effective in schools, clear guidelines, training, support, and cost analysis are needed.
