Engaging students in learning activities is the main responsibility of teacher. The responsibility becomes more challenging when we approach the teaching and learning process through an online platform. Students at all levels, from elementary schools to graduate need to have some specific engagement arrangements in virtual or online platform for their smooth learning. Student engagement and their active attention in learning is extremely vital for attaining desirable learning outcomes. Studies about attention shows that human attention span is 8 seconds only and this human attention span increases significantly to 120 seconds when watching a video. As our educational practices is moving towards the rapid use of digital devices and digital platform, understanding about the student learning engagement in digital platforms becomes crucial. However research in this important condition of teaching learning process is limited. The objectives of the study is to assess different dimensions, factors and strategies for improving student learning engagement in digital platforms. Through a systematic search approach 40 research publications from both India and abroad have been thoroughly examined and assessed. The findings of study suggest that, student learning engagement is a multi-dimensional (behavioral, emotional and cognitive) process which is influenced by a complex interplay of internal and external factors. Other essential findings and recommendations for better student learning engagement in digital platform are subsequently provided.
