Given the prevalence of smart phone devices and Internet usage, more and more schools are embracing the Bring-Your-Own Device (BYOD) policy to make learning more enjoyable and effective. Along with this trend, CloudClassRoom (CCR) was developed to transform smart phone devices into powerful interactive tools for classroom learning. CCR works on every Internet-capable device without further software or plug-in installation. It operates across-platforms, including iOS, Android, and Windows. Once the teacher connects his/her device to CCR, he/she can easily initiate anonymous quizzes. In addition to the traditional forced-choice answer format, CCR enables students to respond with short texts, pictures, or even emoticons. Students’ answers are automatically aggregated, in real time, and analyzed, providing the teacher with a rough picture of student learning progress just in time. To date, approximately 20,000 teachers and students have registered in CCR. More than 170,000 classroom activities have been conducted by using CCR. CCR is a promising tool that will improve interactivity, especially within East Asian classrooms, where students are customarily silent and hesitate to express their ideas. NTNU Chair Professor, Chun-Yen Chang is currently leading an international project to investigate the impact of CCR on classroom learning across Taiwan, Thailand, Vietnam, and other Asian countries. It is expected that the results can inform researchers, teachers, and policy makers, of how to better leverage the potential of mobile technology to boost learning and teaching.
