With the aim of improving the education, we wanted to work on something that can improve students improve their learning. With multimedia content being increasingly used in the context of E-learning, we tried to explore the possibility of sounds in improving the learning.

After getting insights from the several papers on cognitive theory of multimedia-based learning, working memory model and application of sound in the film industry; we prepared a framework where we taught some students using audio cues and checked their performance against those studying without any audio cues. On a set of 20 freshmen engineering students, we demonstrate that the systematic use of audio cues led to an 37.6% relative improvement in learning outcome and 44% relative improvement in long-term retention. Post-study interviews establish that the students associated improved recall and engagement to the presence of audio cues.

Here is the Abstract of the paper: Abstract: Multimedia content is increasingly being used in the context of e-learning. In the absence of classroom-like active interventions by instructors, multimedia-based learning leads to disengagement and shorter attention spans. In this paper, we present a framework for using audio cues interspersed with the content to improve student engagement and learning outcomes. The proposed framework is based on insights from cognitive theory of multimedia learning, modeling of working memory and successful use of audio in the film industry. On a set of 20 freshmen engineering students, we demonstrate that the systematic use of audio cues led to 37.6% relative improvement in learning outcome and 44% relative improvement in long-term retention. Post-study interviews establish that the associated students improved recall and engagement to the presence of audio cues.
