Abstract: This paper presents the experiment and consequent evaluation of
introducing the Logic-ITA in a second year tertiary undergraduate class. The
Logic-ITA is a web-based Intelligent Teaching Assistant system, aimed at
alleviating some of the problems caused by large classes or distance learning.
Its domain of application is the construction of formal proofs in logic. The
system acts as an intermediary between teacher and students: on one hand, it
provides students with an environment to practice formal proofs with feedback
and on the other hand it allows teachers to monitor the class's progress
and mistakes. It is complementary in the sense that it does not aim to replace
any of the existing interactions between teachers and students. Since its
introduction, over 600 students have used the tool. Evaluation shows a
significant improvement in students?assessment results with an effect size of
around 1 sigma.
