The paper discusses a smartphone application with four features: the presentation of audio quiz questions, optical character recognition (OCR) scoring on a server, record management, and an English dictionary. It was tested with about 120 students, in grades 6, 7, and 8, in (I presume) Pakistan. The time spent by teachers grading and recording was significantly reduced, and a teacher reported that “students love technology interaction.”

It seems to be a useful tool, whose functionality could be expanded. The paper is worthwhile reading because it shows how a common piece of technology, an Android smartphone, can accomplish tasks usually done by much more expensive systems. It will be of particular interest to instructors in under-resourced schools and to people thinking about sensible ways to use technology in education. The title mentions “collaboration,” but such is not discussed in the paper.
