In the medical field, doctors and researchers should be able to observe and interpret cell samples. The most widely spread method is to observe samples with a microscope. New methods allow for scanning samples into very large and detailed images. These images can be uploaded to the Cytomine web application and doctors can go through the images at ease. The application includes many functionalities, namely the ability to annotate regions of interest. Currently the ULiege MOOC server is open to the general public (see https//www.fun-mooc.fr). Anyone can take part in the MOOC, but it's mostly used for the bene t of the students studying the medical field at the University of Liege. The students study particular images and are then evaluated at the end of the year. Meanwhile, the Cytomine app has been collecting data on the students' time spent on the website. The main objective is to develop IT tools to analyze data collected. The bulk of the data collected consists of where the students decided to look in the images (Gaze data). Consequently, a tool was implemented to find correlations between students' behavior and the results they obtain during exams. Using Machine Learning techniques, the goal is to predict a student's grade based on how they used the application. This allows for the analysis of specific viewing patterns that can give more insight on how the student used Cytomine. Currently, the model contains 395 students' data with over 2000 features. Extra Trees and Random Forest learning techniques have been applied to attempt to predict grades. Otherwise, other tools were implemented to better visualize these patterns. The idea would be to generate Heatmaps of the students' gaze data (Gazemap). These Gazemaps would be included in the application and users can be given access to this information. This could give teachers the ability to keep track of the students' work.
