Lessons are typically conducted in classrooms. Some teachers take their learners on field trips or find other innovative ways of teaching outside of the classroom, but this happens only on occasion. In most cases it is not practical to have a lesson outside the classroom. The downside of a lesson constrained by the four walls of the classroom is that when the learners leave the room, the lesson is over.
Cell phones can be used to let the lesson continue outside of the classroom. Activities and content can be given for leaners to engage with after they leave the classroom. This means that the classroom is now expanded to the homes of learners, or even to the transport that the learners will use travelling between their homes and school. When learners cannot be taken on field trips, or when they need be educated about other parts of the globe, a cell phone can be used to give them a glimpse into those aspects.
When learners cannot come to school owing to sickness, or when civil unrest prevents them from moving around freely, we can use their cell phones to put the classroom in their homes.
Using cell phones outside of the classroom can enhance any lesson, but it would be particularly useful when a school has a strict no cell phone policy, or where the use of cell phones is prohibited in the classroom. Despite the restrictions, teachers can still expand the walls of their classroom by letting the learners use their devices for learning outside of the classroom.
