Measuring Cognitive Load in eLearning: Can Analytics Detect Overwhelm?
Cognitive load — the mental effort required to process information — is a silent but potent force in eLearning. When cognitive load exceeds a learner's capacity, learning stalls, frustration mounts, and dropout rates rise. But can we measure this invisible burden using learning analytics? More importantly, can we detect cognitive overwhelm before it derails learning ? This article explores how data from LMSs, LRSs, and other platforms can be used to infer cognitive load in digital environments — and what we can do about it. Understanding Cognitive Load in a Digital Learning Context Cognitive Load Theory (CLT) identifies three types of cognitive load: Intrinsic Load : The complexity of the material itself. Extraneous Load : The way information is presented (often a design issue). Germane Load : The mental effort devoted to processing, constructing, and automating schemas. In eLearning, poor instructional design can amplify extraneous load, while interactive or poorl...
