Digital Education: Student Modeling

Student Modeling (BKT) lecture for the Digital Education course on November 11th, 2025.
Instructors: Prof. Tanja Käser, Marta Knežević from the ML4ED Lab

To make the lecture demonstration interactive, we'll run code on EPFL's interactive Jupyter Notebook cluster, Noto! Noto enables everyone to run python code in their browser, without needing an environment set up on your own machine. Here are the steps to get started with Noto.

Setup

Through the following steps, you will log in to Noto, copy the right files you need for the tutorial, and get started running code.

1. Go to the noto.epfl.ch website.
2. You will see a login screen with a big red button called Sign in with Tequila/SWITCHaai. Press this button.
3. You will then see the following loading screen. Wait for less than a minute (usually) until your server spins up!
   
4. Now, you will be presented with a JupyterLab environment. Click on the git symbol (diamond with branches) on the left column.
   
5. Click on the "Clone a Repository" blue button (third one).
   
6. You will see a popup called "Clone a repo". In the space for a URL, copy-paste the following URL: https://github.com/epfl-ml4ed/de_2025.git. Then click the "Clone" button.
   
7. Great! Now you've reached the step where you have all the files you need. Click on the de_2025 folder where all the code is located.
8. If it asks you to "Select Kernel", please select the Python3 Kernel from the dropdown menu. You can also select a kernel by clicking on the top right corner of the notebook.
   

You're all set!
