Does video learning improve learning performance compared to text learning in university students?
An EEG-based machine learning tool can predict student learning performance with 85% precision and identified video as a more efficient learning modality than text.
This study presents a neuroengineering-based machine learning tool developed to predict students' performance under different learning modalities. Neuroengineering tools are used to predict the learning performance obtained through two different modalities: text and video. Electroencephalographic signals were recorded in the two groups during learning tasks, and performance was evaluated with tests. The results show the video group obtained a better performance than the text group. A correlation analysis was implemented to find the most relevant features to predict students' performance, and to design the machine learning tool. This analysis showed a negative correlation between students' performance and the (theta/alpha) ratio, and delta power, which are indicative of mental fatigue and drowsiness, respectively. These results indicate that users in a non-fatigued and well-rested state performed better during learning tasks. The designed tool obtained 85% precision at predicting learning performance, as well as correctly identifying the video group as the most efficient modality.
Ramírez-Moreno et al. (Wed,) conducted a observational in Cognitive performance in learning tasks. Video learning modality vs. Text learning modality was evaluated on Learning performance and prediction precision of the machine learning tool. An EEG-based machine learning tool achieved 85% precision in predicting university students' learning performance and correctly identified video as a more efficient modality than text.
