Abstract: We have developed two systems for feedbacking and sharing students’ viewing responses suited to students’ viewing circumstances in broadcast lectures using mobile devices for feedback (OREAS) and online video feedback (VREAS), respectively. OREAS is able to feedback students’ viewing responses in three different survey modes: Realtime Mode, Author Mode, and User Mode. In addition, the data feedbacked in each of different modes of OREAS can be merged and uploaded and displayed in VREAS ,these systems can be used both as tools for lecture evaluation and as interactive study aids among student peers or effective tools for learning review.OREAS and VREAS were highly evaluated by university’students.
