A basic problem that must be dealt with in order to build an intelligent tutoring system (ITS) in the domain of foreign language teaching is that of establishing what kind of grammatical knowledge has to be included in the domain expert module. Two basic options are possible: (i) to use a naive or pedagogical grammar, comprising knowledge derived from textbooks and school grammars or (ii) to use one of the formal grammars developed by theoretical and computational linguists. | TEACHING THE ENGLISH TENSE INTEGRATING NAIVE AND FORMAL GRAMMARS IN AN INTELLIGENT TUTOR FOR FOREIGN LANGUAGE TEACHING Danilo Fum Bruno Pani 2 and Carlo Tasso 2 1 Dipartimento di Psicologia - ưniversità di Trieste via dellUniversità 7 1-34123 Trieste Italy - fum@ 2 Laboratorio di Intelligenza Artificiale - ưniversità di Udine via Zanon 6 1-33100 Udine Italy - tasso@ ABSTRACT A basic problem that must be dealt with in order to build an intelligent tutoring system ITS in the domain of foreign language teaching is that of establishing what kind of grammatical knowledge has to be included in the domain expert module. Two basic options are possible i to use a naive or pedagogical grammar comprising knowledge derived from textbooks and school grammars or ii to use one of the formal grammars developed by theoretical and computational linguists. The paper discusses the relationships between naive and formal grammars in foreign language teaching and presents as a case study an attempt to integrate the two approaches within ET English Tutor an ITS aimed at helping Italian students master English verb usage. More particularly the paper focuses on the possibility of integrating a naive grammar into a systemic framework. The reliability of the proposed approach is currently being evaluated by means of a series of computational experiments with the Verb Generation Expert of ET. INTRODUCTION A problem that must be dealt with in order to build an ITS in the domain of foreign language teaching is that of establishing what kind of grammatical knowledge has to be included in the Domain Expert module. At first sight two distinct options are possible a to utilize the knowledge contained in textbooks and school grammars b to adopt one of the formal grammars developed by theoretical and computational linguists. Both these solutions have their shortcomings. Traditional grammar textbooks have serious drawbacks which concern both their content
