The Rather Intelligent Little Lisper

Abstract

Abstract This paper describes TRILL, a tutoring system which teaches about the basic Lisp datatypes. While the original design of TRILL was addressing a significant subset of Lisp, the first implementation reduced the set of concepts to its basic datastructures. The paper consists of an outline of the TRILL system as it was first designed, its first implementation, and a summary of work currently in progress, both at the Open University and at DID A ∗EL, to extend some of the ideas used in the first version of the TRILL system.
