Analysis of learners' study logs: mouse trajectories to identify the occurrence of hesitation in solving word-reordering problems

In this paper, we describe a Web application we have been developing in order to help both teachers and learners notice the crucial aspects of solving word-reordering problems (WRPs). Also, we discuss ways to analyze the recorded mouse trajectories, response time, and drag and drop (D&D) logs, because these records are potential indicators of the degree of learners' understanding.
