Deep learning model assesses cognitive load from EEG for online learning

Researchers have developed a hybrid deep learning model combining CNN, LSTM, and attention mechanisms to assess cognitive load using single-channel EEG data from a consumer-grade device. The model achieved up to 78.5% accuracy in distinguishing between easy and difficult online learning content in a within-subject evaluation. The study emphasizes the need for subject-independent evaluation due to the small sample size and releases a reproducible pipeline and a tool for educators to visualize cognitive load heatmaps over educational videos.

IMPACT This research could lead to tools that help educators identify challenging online learning content, potentially improving educational efficacy.
