The OttoLearn system looks at several factors — such as a learner's assigned Mastery Profiles, their past performance, and current mastery strength — to figure out when to prompt them to engage with their training. Using this information, the system also determines how many Activities it should present to the learner so you don't have to.Although you can't specify the number of Activities you want learners to complete in each Training Session or Training Moment, OttoLearn presents Activities in an personalized way to each learner and tries to keep each Session/Moment under 1-2 minutes.
