- The UBC Math Department makes previous final exams available online
- Since 2012 a large team of volunteers writes free hints and solutions
Math Education Resources
Online solutions to math questions - so what?
Math Education Resources
More than just solutions:
Vision for interactive, smart learning portal
Math Education Resources
"Which questions should I work on next?"
question difficulty (user rating)
question difficulty
(multiple choice answers)
important topics in my course
topics I have mastered / struggle with
find similar questions that are harder / easier
First task: predict topic
Online webapp: www.math-education-resources.com
IPython Notebook: https://github.com/BernhardKonrad/ML-MER-VanPy/blob/master/ML-MER.ipynb
In summary
- We built classifier to predict topics of Math questions
- Next step: Combine difficulty rating, course, etc. to expand classifier into question-recommender
- Results can be put to use on webapp immediately
- MER provides a unique database of problems for data scientists to play with
