ABSTRACT
We investigate the use of hints as a form of scaffolding for 4,652 eligible users on a large-scale online learning environment called Isaac, which allows users to answer physics questions with up to five hints. We investigate user behaviour when using hints, users' engagement with fading (the process of gradually becoming less reliant on the hints provided), and hint strategies including Decomposition, Correction, Verification, or Comparison. Finally, we present recommendations for the design and development of online teaching tools that provide open access to hints, including a mechanism that may improve the speed at which users begin fading.

Hints: is it better to give or wait to be asked?
ITS'10: Proceedings of the 10th international conference on Intelligent Tutoring Systems - Volume Part IMany tutoring systems allow students to ask for hints when they need help solving problems, and this has been shown to be helpful. However, many students have trouble knowing when to ask for help or they prefer to guess rather than ask for and read a ...
