- Mobile phones are ubiquitous devices that allow widespread access to the internet and are changing people's habits. - Teachers can use mobile phones in the classroom to enhance motivation through activities like having students take photos, record audio, and create silent movies using the devices. - These activities encourage speaking practice, negotiation of meaning, and collaborative learning through visual, aural and kinesthetic modes. They also use students' real-life mobile devices. - Mobile phones can foster learner autonomy outside the classroom if teachers help students identify language learning apps and resources to use independently on their own devices.
