Introduction to Iltis: An Interactive, Web-Based System for Teaching Logic

TL;DR

Iltis is a web-based interactive system designed to enhance teaching of propositional, modal, and first-order logic by providing immediate feedback and modeling support, aimed at computer science students learning logic.

Contribution

This paper introduces Iltis, a novel web-based platform that supports logic education with interactive modeling and instant feedback, specifically for propositional logic.

Findings

Initial positive feedback from students using Iltis.

System effectively supports learning propositional logic.

Potential for expansion to other logical formalisms.

Abstract

Logic is a foundation for many modern areas of computer science. In artificial intelligence, as a basis of database query languages, as well as in formal software and hardware verification --- modelling scenarios using logical formalisms and inferring new knowledge are important skills for going-to-be computer scientists. The Iltis project aims at providing a web-based, interactive system that supports teaching logical methods. In particular the system shall (a) support to learn to model knowledge and to infer new knowledge using propositional logic, modal logic and first-order logic, and (b) provide immediate feedback and support to students. This article presents a prototypical system that currently supports the above tasks for propositional logic. First impressions on its use in a second year logic course for computer science students are reported.
