HeartCode PALS Online is the online portion of PALS blended learning that will prepare students for hands-on practice and testing of PALS skills. It uses a personalized adaptive algorithm that sets students on the most efficient path to PALS mastery. Students follow a continuously adapting learning path that is personalized by their own inputs: their performance, and their self-reported confidence level related to each probe. The course content is presented in the form of self-directed learning content, probes, and cognitive assessment activities.
