Learning labels are a standard representation of expectations for a task or experience, a way to define learning in skills and skill quantifiers. The goal is to get practitioners and/or publishers to create collections of learning labels. Once the labels are in place, use them to achieve higher level goals – like those of a project, lesson plan, course, or job.
With a collection of labels, a practitioner creates a series by connecting them together based on performance, tasks them to learners, projects, or syllabus, and then grades the learners (or lets the system do the grading through a quiz interface). See this video on how this works. Using a separate app / interface a learner then navigates through the series to reach the learning objectives.
