LiTS - Light Tutoring Systems

 

LiTS is a project for the development of software. It aims to build and evaluate a software prototype of a Light Tutoring System (LiTS).

Learning processes which completion is believed to be well assessed by multiple-choice tests are the target domain of application for LiTS. A LiTS is envisaged to feature a unified set of software tools to set up a course. The course should be set up by stating a course description. In stating the course description, the course's designer assumes a conceptual framework characterised as:

- The knowledge domain of the course will be partitioned into a set of nodes endowed with a relation of learning precedence among nodes; the result is an acyclic graph, or DAG; each node represents a “chunk” of knowledge that the learner is supposed to learn in an “atomic learning act”.

- For each node the designer will provide:

o A presentation of the node.

o A set of conditionally enabled initial learning procedures for the node; a learning procedure is open in content in the sense that it must be understood as a set or sequence of things for the learner to do, not necessarily just to access on-line content.

o A set of sequences of questions, each can be answered through multiple choice, together with the correct pattern of answer for each sequence.

o For each ‘wrong’ answer (or for answer patterns containing “wrong” answers), an error driven learning procedure and / or a (different) selection of initial learning procedure; the default for an error driven learning procedure will be to elicit a contradiction from the false sentence implied by the answer.
