Resumen
This paper describes implementation guidelines for ubiquitous seamless mobile learning featuring the learning-log system named SCROLL (System for Capturing and Reminding of Learning Log). This system helps users to share and remind ubiquitous learning experiences. We review recent researches on mobile assisted learning in order to set pedagogically-based guidelines for instructors, learning environment designers and the administrative end or decision makers including ICT coordinator, and local authorities. Main foci in our guidelines are for language teachers to practice SROLL-based mobile learning in their classes for both in-class and out-class learning according to their situation or conditions. Our goal is to help educators to implement an effective seamless mobile learning environment with SCROLL.
