The present research focuses on the use of the relative pronoun que (that/where) in the production of the college students of the Instituto Nacional de Educação de Surdos (INES). Mainly, this paper proposes a workshop based on the referred pronoun in the academic writing of both deaf and listeners, college students of the Institute. In order to do so, the bilingual approach is used and the written Portuguese functions as the second language whereas the Brazilian Sign Language (Libras) functions as the first. Based on the written production of post graduation students of the Pontifícia Universidade Católica from Rio de Janeiro (PUC-Rio), three syntactic functions of the relative pronoun que (that) are selected for analysis, namely, subject, direct object and adjunct. Basically, there is general rise in the production of the pronoun for the three suggested functions. Nonetheless, there is reduction for the direct object and the adjunct in the exercise in which students may put sentences together and for the adjunct in the exercise of completing sentences. The results are properly justified what proves the efficiency of the workshop for both deaf and listeners.
