EVALUATION OF TWO CAMERA-BASED APPROACHES FOR COLLECTING STUDENT FEEDBACK
Published: 2 Oct 2014
Abstract: Many educators have demonstrated that use of the clicker-based Instant Feedback System (IFS) during lectures advances in students' active learning that results in better academic achievements. The wide proliferation of smartphones and tablets (having high-resolution digital cameras and powerful computing processors) means that simple and inexpensive camera-based feedback systems (CBFS) can and should be developed. In this paper, the usefulness and reliability of two CBFS implementations will be analyzed. A number of tests of the two systems were run in big classes (more than 50 students) and in small classes (less than 20 students). Pedagogical impact of both CBFS implementations is discussed.
