Abstract

This work develops a method for incorporation into an online
system to provide carefully
targeted guidance and feedback to students. The student answers online
multiple choice questions on
a selected topic, and their responses are sent to a SnapDrift
neural network trained with responses
from past students. Snapdrift
is able to categorise the learner's responses as having a significant level
of similarity with a subset of the students it has previously categorised. Each category is associated
with feedback composed by the lecturer on the basis of the level of understanding and prevalent
misconceptions of that categorygroup
of students. In this way the feedback addresses the level of
knowledge of the individual and guides them towards a greater understanding of particular concepts.
The feedback is conceptbased
rather than tied to any particular question, and so the learner is
encouraged to retake the same test and receives different feedback depending on their evolving state of
knowledge. This approach has been applied to two data sets related to topics from an Introduction to
Computer System module and a Research Skills module.
