This paper describes a ubiquitous learning log system called SCROLL (System for Capturing and Reminding of Ubiquitous Learning Log). The aim of SCROLL is to aid users to simply capture the learning logs they have learned, review and reflect their old learning logs, reuse the knowledge when in need, be reminded at right time at right place and be recommended others' learning logs properly. Both its functions and architecture are introduced in this paper. © 2012 IEEE.
