This document discusses the Tin Can API, an open standard for tracking learning experiences outside of a learning management system (LMS). It describes how the Tin Can API works by allowing any learning activity to send simple statements to a learning record store, freeing learners' data from the LMS. Examples are given of different types of learning experiences, like watching a YouTube video or completing a mobile app topic, and how student activities could be recorded and statements sent to the LRS. Challenges of using self-reported data are also mentioned. Overall, the document provides an overview of the Tin Can API and how it can be used to track a variety of online learning activities and experiences outside of an LMS.
