Subjective Measure of Cognitive Load Depends on Participants’ Content Knowledge Level

Cognitive load theory (CLT) posits the classic view that cognitive (CL) has three-components: intrinsic, extraneous and germane. Prior research shown subjective ratings are valid measures of different CL subtypes. To a lesser degree, how validity these depends on learner characteristics not been studied. In this research, we explored extent to which specific set upon learners’ prior knowledge. Specifically, developed an eight-item survey measure three aforementioned subtypes perceived by participants in testing environment. first experiment ( N = 45) categorized eight items into groups based similarity themes. Most sorted consistent with threefold construct CLT. Interviews subgroup 13) provided verbal evidence corroborating their understanding was second 139) completed twice after taking conceptual test pre/post setting. A principal component analysis (PCA) revealed two-component structure for when content knowledge level initially lower, but three-component improved higher level. The results seem suggest low failed differentiate targeting intrinsic from those measuring load. third 40) consisting problems imposing levels reveals rated each subtype manipulated. Thus, is decently effective types CL. We instructors use instrument have established certain relevant
