Develop the Interactive Feedback Portfolio System with iBeacon Technology Applied in Flipped Classroom Learning Activities.

The paper proposes an interactive feedback portfolio (IFEP) system with iBeacon technology which is used in classroom to support the flipped classroom learning activities. The use of the IFEP system aims at promoting high interaction in classroom learning, which consists of APPs students used and web-interface functions teachers utilized. Students enable the APP in their smart phones and then the APP scan iBeacon devices. The detection statuses of iBeacon devices in classrooms can be automatically recorded in the cloud space. As a result, students' presence in classroom can be obtained automatically. Teachers can use another function the IFEP system offers to promote the interaction in classroom via displaying questions on the front screen in classroom. Meanwhile, it pushes (multicasts) these questions to students' smart phones via web-socket technology. Subsequently, students employ APP to feedback their responses to these questions. During collecting students' responses, the system also exhibits the temporary results of students' responses on screen and displays count-down time signal. This way can inspire students' interaction and interest to join the quiz-like activities. Teachers can quickly get the results of responses for students' answers. These results including students' presence in classroom and correction rates students' responses can be readily analyzed for their correlations on learning performance in the future. Moreover, teachers can quickly obtain students' learning achievements in classroom and then teachers may adjust their instructional strategies.
