The purpose of this chapter is to describe the use of an electronic learning journal in the portfolio process and the construction of a digital portfolio. The authors discuss the problems that have arisen during the learning and tutoring process of various traditional (paper) learning journals. The problems of traditional learning journals and their tutoring have been the following: (1) low extent of tutoring and evaluation during the process; (2) when the learning journal is the object of external assessment, it is not used as a tool for profound reflection (private vs. public dimensions of the learning journal); and (3) there has been a lack of a user-friendly tools with which to construct a Web-based learning portfolio. In this chapter the authors discuss the basic elements of ONNI–The Learning Journal, as well as how this electronic tool can help in solving the problems mentioned above. ONNI is presently being experimented on at the University of Kuopio, but it will also be developed to become a tool for every Finnish college student and to better support learning from peers as well as lifelong learning.
