Exploring the potential of mobile phones for active learning in the classroom

Research has shown that educational technology can broaden and enhance the use of active learning in large classrooms. An educational technology platform often relies on students to bring laptops or specialized wireless devices like clickers to interact through the system. Mobile phones are an attractive alternative, as most students already possess them, they have more capabilities than dedicated clickers, and yet are small enough to minimize interference with note taking on a classroom desk.This paper presents the design and use of a mobile phone extension to Ubiquitous Presenter, which allows students to submit solutions to active learning exercises in the form of text or photo messages. In an exploratory study, students found that text messaging worked well for exercises with multiple choice or short answers. Entering symbols common to computer science was difficult. Many problems were more suitable to photo messaging of a handwritten answer, although image quality must be managed. The phone's small size left space for the use of a notebook. The students had concerns about the message charges that would accrue in use. In conclusion, we offer recommendations to instructors and system designers interested in leveraging mobile phones to increase communication in the classroom.
