Cognitive Load Predictor
Estimate cognitive load based on training design parameters, informed by Cognitive Load Theory (Sweller).
Instructional Delivery Method
The instructional delivery method influences cognitive load because different formats place different demands on attention, memory and learner interaction.Select the primary format used to deliver the learning experience.

💻Interactive eLearning
Interactive eLearning combines multimedia, learner interaction and assessments. Well-designed experiences can improve engagement but excessive interaction may increase extraneous cognitive load.
Design parameters
Adjust to see how load shifts in real time.
Training durationTotal time-on-task increases fatigue and depletes working memory. Longer sessions raise extraneous load unless broken into spaced chunks — expect the CL score to climb as duration grows.60min
Video durationVideo occupies both visual and verbal channels. Long unbroken video segments amplify extraneous load; keeping this low or segmenting it lowers the predicted score.20min
InteractionsMeaningful interactions build germane load and schema formation. A moderate number reduces the CL score, but excessive clicks add extraneous load and push it back up.6
AssessmentsLow-stakes assessments trigger retrieval practice — a strong germane-load contributor. Adding assessments typically lowers the overall CL score by strengthening learning.2
Information densityDensity reflects how much new information is packed per screen or minute. High density directly raises intrinsic load and is one of the strongest drivers of the CL score.6/10
Prior knowledgeLearners with more prior knowledge process content via existing schemas, lowering intrinsic load. Higher prior knowledge reduces the CL score for the same material.5/10

Instructional design recommendations
💻 Interactive eLearning- Limit unnecessary interactions.
- Reduce split attention.
- Use progressive disclosure.
- Provide immediate feedback.
- Keep navigation simple.
