This study aimed to cluster learners based on the structures of the knowledge maps they created. Learners drew their own knowledge maps to reflect their learning activities. Our system collected individual knowledge maps from many learners and clustered them to generate an integrated version of the knowledge maps of each cluster. We applied the…

Collaborative problem-solving (CPS) as a key competency required in the 21st century. There has been an increasing need to understand CPS since it involves not only cognitive but also social processes, and thus its process is difficult to examine. Recent research has highlighted that computer-based learning environments provide an opportunity for…

We propose a data driven method for decomposing population level learning curve models into mutually exclusive distinctive groups each consisting of similar learning trajectories. We validate this method on six knowledge components from the log data from an online tutoring system ASSISTment. Preliminary analysis reveals interpretable patterns of…

User clustering algorithms have been introduced to analyze users' learning behaviors and help to provide personalized learning guides in traditional Web-based learning systems. However, the explicit and implicit coupled interactions, which means the correlations between user attributes generated from learning actions, are not considered in these…

In free recall learning, taxonomic organization has been studied almost to the exclusion of alternative types of organization. Consequently, little is known about how learning and memory are affected by alternative types of organizations. The present experiments explored the differential effects of two kinds of organization on free recall…

This research studied the effects of instructions on children's recall in a free recall learning task. Also investigated were developmental trends, including expected superiority of older children in recall and spontaneous formation of stable organizational groupings. A third area of study concerned the possibility that younger children benefit…
