Major Scope changes

  • Movement of payment module and discussion board as well as flagging to good to have functions as clients wants to add more specification and for us to focus more on the exam and report module

Schedule Highlights

  • Removing of UAT1 due to it being an internal UAT as advised by Prof Ben during acceptance
  • Renaming of UAT1, UAT2, UAT3, UAT4
  • Rescheduling of UAT1 and UAT2 due to client's availability, as we are utilising Basecamp Learning Centre students.
  • Including A/B testing to check on algorithm effectiveness

Technical Complexity

Scoring Algorithm

  • Overwrite differs from traditional marking systems whereby all students are given fixed timing on a certain set of questions
  • The scoring algorithm aims to accurately measure student’s competency for every question and documents student’s data trail precisely
Nk techD.png
  • As seen from the diagram, the app first gets factors such as time taken, level of difficulty after a student does a question.
  • The app queries the database for information such as average time taken of question by all students and number of questions answered correctly consecutively.
  • Using these 4 factors and the algorithm, a score for that question will be calculated. We will also update an average time taken of the question by all students and update the number of questions answered correctly consecutively.


Reinforcement Learning

  • Using a purely arbitrary scoring algorithm mentioned above is not a comprehensive solution in determining a student’s competency in a certain subject with many topics.
  • A holistic and dynamic testing environment is required to better analyse student’s full capabilities and imitate an examination condition
  • Utilising Multi-Armed Bandit Algorithm to predict student’s weak topics within the shortest number of trials possible
Nk mlD.png
  • Every question answered by student will run the Upper Confidence Bound 1 algorithm.
  • Algorithm would evaluate student’s performance and rank all topics in terms of their growth potential and likely hood of generating the most ‘rewards’ (weakest topic)
  • Machine would then decide between ‘exploration’ vs ‘exploitation’ in determining whether to generate a question of a different topic or proceed with testing the same topic
  • This interactive element between student and machine for each question allows for reinforcement learning to occur as machine would be able to better predict student’s strength and weakness more accurately after each round
