How does Blutick’s AI work?

Blutick works as a reactive AI, applying a large number of algorithmic tests to the student’s input and then generating a probabilistic assessment of the best response if the student has made a mistake. It takes into account a wide range of factors, including the question context, the stage of working the student is currently at, and the mathematical working itself. All of the lines of feedback are written by real Maths teachers, and are designed to be encouraging and positive while at the same time pointing the student in the right direction, just as a real teacher would do.

Blutick also stores and processes the millions of lines of working that have been entered into the system, and generates suggestions for scenarios that currently don’t offer intelligent feedback. These are then examined by teachers and appropriate feedback written and built into the system. That way Blutick gets cleverer over time.

Finally, Blutick tracks the ‘success rate’ of each feedback message in terms of how likely the student is to enter a correct line of working after having received the message. It can then test new formulations of the message to see which are most successful, and in which contexts. Just as a human teacher improves their ability to identify students’ mistakes and give them appropriate feedback, Blutick learns what works best and what doesn’t, steadily creating a more effective teaching and feedback platform.
