摘要：With the increasing use of digital learning materials in higher education, the accumu?lated operational log data provide a unique opportunity to analyzing student learn?ing behaviors and their efects on student learning performance to understand how students learn with e-books. Among the students’ reading behaviors interacting with e-book systems, we fnd that jump-back is a frequent and informative behavior type. In this paper, we aim to understand the student’s intention for a jump-back using user learning log data on the e-book materials of a course in our university. We at frst formally defne the “jump-back” behaviors that can be detected from the click event stream of slide reading and then systematically study the behaviors from diferent perspectives on the e-book event stream data. Finally, by sampling 22 learning materi?als, we identify six reading activity patterns that can explain jump backs. Our analysis provides an approach to enriching the understanding of e-book learning behaviors and informs design implications for e-book systems.
