ABSTRACT OF DISSERTATION
E-Learning is transforming the delivery method of education. Today, millions of students take self-paced online courses. However, the content and language complexity often hinders comprehension, and that with lack of immediate help from the instructor leads to weaker learning outcomes. Ability to predict difficult content in real time enables eLearning systems to adapt content as per students' level of learning. The recent introduction of low-cost eye trackers has opened a new class of applications based on eye response. Eye tracking devices can record eye response on the visual element or concept in real time. The response and the variations in eye response to the same concept over time may be indicative of the levels of learning. We have analyzed reading patterns using eye tracker and derived eye response features based on psycholinguistics, contextual information processing, anticipatory behavior analysis, recurrence fixation analysis, and pupils' response. We use eye and pupil responses to predict the level of learning of a term/concept for individuals.

The main contribution is the spatio-temporal analysis of the eye response to a term/concept to derive relevant first pass (spatial) and reanalysis (temporal) eye response features. A model, built using these derived features, uses our proposed feature weighted linguistics classifier (FWLC) to achieve a prediction accuracy of 90.54% an increase of 23.62% over baseline and 29.54% over the first-pass variant of baseline (majority voting classifier). On comparing the performance of FWLC with other frequently used machine learning classifiers, FWLC achieves highest true positive rate. This research has applications into adaptive eLearning and learning assessment.
