The purpose of the present small-scale study was to investigate the factor structure of an adapted, 13-item subjective English cognitive load scale in a fully online learning context. To serve this purpose, adult online learners enrolled in a fully online graduate program completed the adapted English cognitive load scale at the end of an eight-week academic session. Exploratory factor analyses including a screen plot and eigenvalues introduced two or three factors to be extracted. However, a parallel analysis revealed two factors only that seem to correspond to intrinsic and extraneous loads. A following confirmatory factor analysis using the same sample affirmed the two-factor structure.These results are inline with the recent theoretical assumption that total cognitive load consists of intrinsic and extraneous loads only whereas germane load emanates from mental effort spent on dealing with intrinsic load. Consequently, the current research provides evidence-based insights into a two-factor structure of the cognitive load scale thereby clarifying previous inconclusive findings to some extent.
